ExtReact Docs Help

Introduction

The documentation for the ExtReact product diverges somewhat from the documentation of other Sencha products. The sections below describe documentation for all products except where indicated as unique to ExtReact.

Terms, Icons, and Labels

Many classes have shortcut names used when creating (instantiating) a class with a configuration object. The shortcut name is referred to as an alias (or xtype if the class extends Ext.Component). The alias/xtype is listed next to the class name of applicable classes for quick reference.

ExtReact component classes list the configurable name prominently at the top of the API class doc followed by the fully-qualified class name.

Access Levels

Framework classes or their members may be specified as private or protected. Else, the class / member is public. Public, protected, and private are access descriptors used to convey how and when the class or class member should be used.

Member Types

Member Syntax

Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).

lookupComponent ( item ) : Ext.Component
protected

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

Parameters

item :  Object

The config object being added.

Returns
Ext.Component

The component to be added.

Let's look at each part of the member row:

Member Flags

The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Class Icons

- Indicates a framework class

- A singleton framework class. *See the singleton flag for more information

- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)

- Indicates that the class, member, or guide is new in the currently viewed version

Member Icons

- Indicates a class member of type config

Or in the case of an ExtReact component class this indicates a member of type prop

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.

Getter and Setter Methods

Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.

ExtReact component classes do not hoist the getter / setter methods into the prop. All methods will be described in the Methods section

History Bar

Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.

Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.

If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.

Search and Filters

Both API docs and guides can be searched for using the search field at the top of the page.

On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.

The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.

Clicking on an empty search field will show your last 10 searches for quick navigation.

API Doc Class Metadata

Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:

Expanding and Collapsing Examples and Class Members

Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.

Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.

Desktop -vs- Mobile View

Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:

Viewing the Class Source

The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

Defaults to:

'Ext.Base'

$configPrefixed : Boolean
readonly ro private pri

<ExtD3_treemap $configPrefixed="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.$configPrefixed = true;
let $configPrefixed = element.$configPrefixed;

Defaults to:

true

Available since: 5.0.0

$configStrict : Boolean
readonly ro private pri

<ExtD3_treemap $configStrict="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.$configStrict = true;
let $configStrict = element.$configStrict;

The value true instructs the initConfig method to only honor values for properties declared in the config block of a class. When false, properties that are not declared in a config block will be placed on the instance.

Defaults to:

true

Available since: 5.0.0

$configTransforms : Object / Array
readonly ro private pri

<ExtD3_treemap $configTransforms="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.$configTransforms = { };
let $configTransforms = element.$configTransforms;

A prototype-chained object storing transform method names and priorities stored on the class prototype. On first instantiation, this object is converted into an array that is sorted by priority and stored on the constructor.

Defaults to:

{}

$eventOptions

let element = document.body.querySelector('ExtD3_treemap');
element.$vetoClearingPrototypeOnDestroy = 'value';
let $vetoClearingPrototypeOnDestroy = element.$vetoClearingPrototypeOnDestroy;

We don't want the base destructor to clear the prototype because our destroyObservable handler must be called the very last. It will take care of the prototype after completing Observable destruction sequence.

Defaults to:

true

activeAnimation
readonly ro private pri

<ExtD3_treemap activeAnimation="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.activeAnimation = 'value';
let activeAnimation = element.activeAnimation;

let element = document.body.querySelector('ExtD3_treemap');
element.alwaysOnTop = true;
let alwaysOnTop = element.alwaysOnTop;

A flag indicating that this component should be above its floated siblings.

This may be a positive number to prioritize the ordering of multiple visible always on top components.

This may be set to a negative number to prioritize a component to the bottom of the z-index stack.

Defaults to:

false

Available since: 6.2.0

ariaAttributes : Object

<ExtD3_treemap ariaAttributes="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.ariaAttributes = { };
let ariaAttributes = element.ariaAttributes;

An object containing ARIA attributes to be set on this Component's ARIA element. Use this to set the attributes that cannot be determined by the Component's state, such as aria-live, aria-flowto, etc.

Note that this config is only meaningful at the Component rendering time, and setting it after that will do nothing.

Defaults to:

null

ariaDescribedBy : String
immutable imm

<ExtD3_treemap ariaDescribedBy="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.ariaDescribedBy = 'value';
let ariaDescribedBy = element.ariaDescribedBy;

DOM selector for a child element that is to be used as description for this Component, set in aria-describedby attribute. The selector works the same way as ariaLabelledBy.

ariaEl : String
readonly ro private pri

<ExtD3_treemap ariaEl="value" />
let element = document.body.querySelector('ExtD3_treemap');
let ariaEl = element.ariaEl;

The name of the Component property that holds a reference to the Element that serves as that Component's ARIA element. This property will be replaced with the actual Element reference after rendering.

Most of the simple Components will have their main element as ariaEl.

Defaults to:

'el'

Available since: 6.0.0

ariaLabel : String
immutable imm

<ExtD3_treemap ariaLabel="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.ariaLabel = 'value';
let ariaLabel = element.ariaLabel;

ARIA label for this Component. It is best to use ariaLabelledBy option instead, because screen readers prefer aria-labelledby attribute to aria-label. ariaLabel and ariaLabelledBy config options are mutually exclusive.

ariaLabelledBy : String
immutable imm

<ExtD3_treemap ariaLabelledBy="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.ariaLabelledBy = 'value';
let ariaLabelledBy = element.ariaLabelledBy;

DOM selector for a child element that is to be used as label for this Component, set in aria-labelledby attribute. If the selector is by id, the label element can be any existing element, not necessarily a child of the main Component element.

ariaLabelledBy and ariaLabel config options are mutually exclusive, and ariaLabelledBy has the higher precedence.

ariaRenderAttributes : Object
readonly ro private pri

<ExtD3_treemap ariaRenderAttributes="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.ariaRenderAttributes = { };
let ariaRenderAttributes = element.ariaRenderAttributes;

Instance specific ARIA attributes to render into Component's ariaEl. This object is only used during rendering, and is discarded afterwards.

ariaRole : String
readonly ro

<ExtD3_treemap ariaRole="value" />
let element = document.body.querySelector('ExtD3_treemap');
let ariaRole = element.ariaRole;

ARIA role for this Component, defaults to no role. With no role, no other ARIA attributes are set.

autoGenId : Boolean
readonly ro private pri

<ExtD3_treemap autoGenId="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.autoGenId = true;
let autoGenId = element.autoGenId;

true indicates an id was auto-generated rather than provided by configuration.

Defaults to:

false

Available since: 6.7.0

axisLock : Boolean

<ExtD3_treemap axisLock="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.axisLock = true;
let axisLock = element.axisLock;

If true, then, when showBy or alignTo fallback on constraint violation only takes place along the major align axis.

That is, if alignment "l-r" is being used, and axisLock: true is used, then if constraints fail, only fallback to "r-l" is considered.

Defaults to:

null

baseCls
readonly ro protected pro

<ExtD3_treemap baseCls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.baseCls = 'value';
let baseCls = element.baseCls;

The base CSS class to apply to this widget's element. Used as the prefix for ui-specific class names. Defaults to the value of classCls or (x- + the xtype) of the widget if classCls is null

Defaults to:

null

bind : Object / String

<ExtD3_treemap bind="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.bind = 'value';
let bind = element.bind;

Setting this config option adds or removes data bindings for other configs. For example, to bind the title config:

 var panel = Ext.create({
     xtype: 'panel',
     bind: {
         title: 'Hello {user.name}'
     }
 });

To dynamically add bindings:

 panel.setBind({
     title: 'Greetings {user.name}!'
 });

To remove bindings:

 panel.setBind({
     title: null
 });

The bind expressions are presented to Ext.app.ViewModel#bind. The ViewModel instance is determined by lookupViewModel.

Note: If bind is passed as a string, it will use the Ext.Component#property-defaultBindProperty for the binding.

Defaults to:

null

border : Boolean

<ExtD3_treemap border="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.border = true;
let border = element.border;

Enables or disables bordering on this component. The following values are accepted:

  • null or `true (default): Do nothing and allow the border to be specified by the theme.
  • false: suppress the default border provided by the theme.

Please note that enabling bordering via this config will not add a border-color or border-style CSS property to the component; you provide the border-color and border-style via CSS rule or style configuration (if not already provide by the theme).

Using style:

Ext.Viewport.add({
    centered: true,
    width: 100,
    height: 100,

    style: 'border: 1px solid blue;'
    // ...
});

Using CSS:

Ext.Viewport.add({
    centered: true,
    width: 100,
    height: 100,

    cls: 'my-component'
    // ...
});

And your CSS file:

.my-component {
    border: 1px solid red;
}

Defaults to:

null

bottom : Number / String

<ExtD3_treemap bottom="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.bottom = 'value';
let bottom = element.bottom;

The absolute bottom position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

busyLayoutText : String

<ExtD3_treemap busyLayoutText="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.busyLayoutText = 'value';
let busyLayoutText = element.busyLayoutText;

The text to show when the layout is in progress.

Defaults to:

'Layout in progress...'

centered : Boolean

<ExtD3_treemap centered="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.centered = true;
let centered = element.centered;

Configure this as true to have this Component centered within its Container. Setting this value to true will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

false

classCls
readonly ro

<ExtD3_treemap classCls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.classCls = 'value';
let classCls = element.classCls;

A CSS class to apply to the main element that will be inherited down the class hierarchy. Subclasses may override this property on their prototype to add their own CSS class in addition to the CSS classes inherited from ancestor classes via the prototype chain. For example

Ext.define('Foo', {
    extend: 'Ext.Widget',
    classCls: 'foo'
});

Ext.define('Bar', {
    extend: 'Foo',
    classCls: 'bar'
});

var bar = new Bar();

console.log(bar.element.className); // outputs 'foo bar'

Defaults to:

Ext.baseCSSPrefix + 'component'

classClsRoot
readonly ro protected pro

<ExtD3_treemap classClsRoot="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.classClsRoot = 'value';
let classClsRoot = element.classClsRoot;

When set to true during widget class definition, that class will be the "root" for classCls inheritance. Derived classes may set this to true to avoid inheriting a classCls from their superclass.

Defaults to:

true

clearPropertiesOnDestroy : Boolean / "async"
readonly ro protected pro

<ExtD3_treemap clearPropertiesOnDestroy="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.clearPropertiesOnDestroy = true;
let clearPropertiesOnDestroy = element.clearPropertiesOnDestroy;

Setting this property to false will prevent nulling object references on a Class instance after destruction. Setting this to "async" will delay the clearing for approx 50ms.

Defaults to:

true

Available since: 6.2.0

clearPrototypeOnDestroy : Boolean
readonly ro private pri

<ExtD3_treemap clearPrototypeOnDestroy="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.clearPrototypeOnDestroy = true;
let clearPrototypeOnDestroy = element.clearPrototypeOnDestroy;

Setting this property to true will result in setting the object's prototype to null after the destruction sequence is fully completed. After that, most attempts at calling methods on the object instance will result in "method not defined" exception. This can be very helpful with tracking down otherwise hard to find bugs like runaway Ajax requests, timed functions not cleared on destruction, etc.

Note that this option can only work in browsers that support Object.setPrototypeOf method, and is only available in debugging mode.

Defaults to:

false

Available since: 6.2.0

clipScene : Boolean

<ExtD3_treemap clipScene="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.clipScene = true;
let clipScene = element.clipScene;

If the scene elements that go outside the scene and into the padding area should be clipped. Note: stock D3 components are not designed to work with this config set to true.

Defaults to:

false

cls : String / String[]

<ExtD3_treemap cls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.cls = 'value';
let cls = element.cls;

The CSS class to add to this widget's element, in addition to the baseCls. In many cases, this property will be specified by the derived widget class. See userCls for adding additional CSS classes to widget instances (such as items in a <ExtContainer/>).

Defaults to:

null

colorAxis : Ext.d3.axis.Color

<ExtD3_treemap colorAxis="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.colorAxis = 'value';
let colorAxis = element.colorAxis;

A Ext.d3.axis.Color config or an instance. By default (if no 'colorAxis' config is given) all nodes are assigned a unique color from the d3.scale.category20c scale (until the colors run out, then we start to reuse them) based on the value of the name field.

Defaults to:

{
    scale: {
        type: 'ordinal',
        // The last 4 colors are shades of gray.
        range: 'd3.schemeCategory20c.slice(0, -4)'
    },
    field: 'name'
}

componentCls : String

<ExtD3_treemap componentCls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.componentCls = 'value';
let componentCls = element.componentCls;

The CSS class used by a subclass of the D3 Component. Normally, the lower-cased name of a subclass.

Defaults to:

''

constrainAlign : String / Ext.util.Region / Ext.dom.Element

<ExtD3_treemap constrainAlign="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.constrainAlign = 'value';
let constrainAlign = element.constrainAlign;

A specification of the constraint to apply when showBy or alignTo is called to align a floated or positioned component.

Defaults to the parent container for positioned components (components which have their top, right, bottom or left set to move them out of their container's layout flow).

Defaults to the viewport for floated components.

May be a Ext.ComponentQuery selector to find an ancestor component to constrain within.

May be false to specify that constraining is not applied.

You may also specify an element, or a Ext.util.Region

Defaults to:

null

containsFocus : Boolean
readonly ro

<ExtD3_treemap containsFocus="true" />
let element = document.body.querySelector('ExtD3_treemap');
let containsFocus = element.containsFocus;

true if this currently focused element is within this Component's or Container's hierarchy. This property is set separately from hasFocus, and can be true when hasFocus is false.

Examples:

  • Text field with input element focused would be: focusable: true, hasFocus: true, containsFocus: true

  • Date field with drop-down picker currently focused would be: focusable: true, hasFocus: false, containsFocus: true

  • Form Panel with a child input field currently focused would be: focusable: false, hasFocus: false, containsFocus: true

See also hasFocus.

Defaults to:

false

contentEl : Ext.dom.Element / HTMLElement / String

<ExtD3_treemap contentEl="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.contentEl = 'value';
let contentEl = element.contentEl;

The configured element will automatically be added as the content of this component. When you pass a string, we expect it to be an element id. If the content element is hidden, we will automatically show it.

Defaults to:

null

controller : String / Object / Ext.app.ViewController

<ExtD3_treemap controller="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.controller = 'value';
let controller = element.controller;

A string alias, a configuration object or an instance of a ViewController for this container. Sample usage:

Ext.define('MyApp.UserController', {
    alias: 'controller.user'
});

Ext.define('UserContainer', {
    extend: 'Ext.container.container',
    controller: 'user'
});
// Or
Ext.define('UserContainer', {
    extend: 'Ext.container.container',
    controller: {
        type: 'user',
        someConfig: true
    }
});

// Can also instance at runtime
var ctrl = new MyApp.UserController();
var view = new UserContainer({
    controller: ctrl
});

Defaults to:

null

data : Object

<ExtD3_treemap data="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.data = { };
let data = element.data;

The initial set of data to apply to the tpl to update the content area of the Component.

Note: Data will be appended to any existing data.

Defaults to:

null

defaultBindProperty : String
readonly ro

<ExtD3_treemap defaultBindProperty="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.defaultBindProperty = 'value';
let defaultBindProperty = element.defaultBindProperty;

This property is used to determine the property of a bind config that is just the value. For example, if defaultBindProperty="value", then this shorthand bind config:

 bind: '{name}'

Is equivalent to this object form:

 bind: {
     value: '{name}'
 }

The defaultBindProperty is set to "value" for form fields and to "store" for grids and trees.

Defaults to:

'html'

defaultCls
readonly ro

<ExtD3_treemap defaultCls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.defaultCls = 'value';
let defaultCls = element.defaultCls;

Class names used by this component. See onClassExtended.

Defaults to:

{
    links: Ext.baseCSSPrefix + 'd3-links',
    nodes: Ext.baseCSSPrefix + 'd3-nodes',
    link: Ext.baseCSSPrefix + 'd3-link',
    node: Ext.baseCSSPrefix + 'd3-node',
    root: Ext.baseCSSPrefix + 'd3-root',
    label: Ext.baseCSSPrefix + 'd3-label',
    parent: Ext.baseCSSPrefix + 'd3-parent',
    leaf: Ext.baseCSSPrefix + 'd3-leaf',
    selected: Ext.baseCSSPrefix + 'd3-selected',
    expanded: Ext.baseCSSPrefix + 'd3-expanded'
}

defaultListenerScope : Boolean

<ExtD3_treemap defaultListenerScope="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.defaultListenerScope = true;
let defaultListenerScope = element.defaultListenerScope;

If true, this component will be the default scope (this pointer) for events specified with string names so that the scope can be dynamically resolved. The component will automatically become the defaultListenerScope if a controller is specified.

See the introductory docs for Ext.container.Container for some sample usages.

NOTE: This value can only be reliably set at construction time. Setting it after that time may not correctly rewire all of the potentially effected listeners.

Defaults to:

false

defs
readonly ro private pri

<ExtD3_treemap defs="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.defs = 'value';
let defs = element.defs;

See getDefs.

Defaults to:

null

destroyed : Boolean
readonly ro

<ExtD3_treemap destroyed="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.destroyed = true;
let destroyed = element.destroyed;

This property is set to true after the destroy method is called.

Defaults to:

false

disabled : Boolean

<ExtD3_treemap disabled="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.disabled = true;
let disabled = element.disabled;

Whether or not this component is disabled

Defaults to:

null

displayed : Boolean

<ExtD3_treemap displayed="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.displayed = true;
let displayed = element.displayed;

Set to true to call show and false to call hide. Unlike the hidden config, changing this config will potentially involve animations to show or hide the component.

Defaults to:

null

Available since: 6.5.0

dockPositions
readonly ro private pri

<ExtD3_treemap dockPositions="value" />
let element = document.body.querySelector('ExtD3_treemap');
let dockPositions = element.dockPositions;

Defaults to:

{
    top: true,
    right: true,
    bottom: true,
    left: true
}

docked : String

<ExtD3_treemap docked="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.docked = 'value';
let docked = element.docked;

The dock position of this component in its container. Can be left, top, right or bottom.

Notes

You must use a HTML5 doctype for docked bottom to work. To do this, simply add the following code to the HTML file:

<!doctype html>

So your index.html file should look a little like this:

<!doctype html>
<html>

draggable : Boolean / Object / Ext.drag.Source

<ExtD3_treemap draggable="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.draggable = true;
let draggable = element.draggable;

Set to true to allow this component to be dragged. This can also be the config object for the Ext.drag.Source that will manage the drag.

Defaults to:

null

element : Object
readonly ro protected pro

<ExtD3_treemap element="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.element = { };
let element = element.element;

A configuration object for Ext.Element.create() that is used to create the Element template. Subclasses should avoid overriding this property and instead add elements using template.

Supports all the standard options of a Ext.Element.create() config and adds 3 additional options:

  1. reference - this option specifies a name for Element references. These references names become properties of the Widget instance and refer to Ext.Element instances that were created using the template:

      element: {
          reference: 'element',
          children: [{
              reference: 'innerElement'
          }]
      }
    

After construction of a widget the reference elements are accessible as follows:

var foo = new FooWidget(),
    innerEl = foo.innerElement; // an Ext.Element that wraps the innerElement

The reference attribute is optional, but all Widgets must have a 'element' reference on some element within the template (usually the outermost one).

  1. listeners - a standard listeners object as specified by Ext.mixin.Observable.

      element: {
          reference: 'element',
          listeners: {
              click: 'onClick'
          },
          children: [{
              reference: 'innerElement',
              listeners: {
                  click: 'onInnerClick'
              }
          }]
      }
    

Since listeners cannot be attached without an Ext.Element reference the reference property MUST be specified in order to use listeners.

The Widget instance is used as the scope for all listeners specified in this way, so it is invalid to use the scope option in the listeners config since it will always be overwritten using this.

  1. uiCls - a suffix to be appended to the ui-specific CSS class for each ui for this widget. These ui classes are constructed by appending the ui to each classCls or baseCls for the widget. As such, uiCls should never be used on the main element reference, as its uiCls is computed automatically.

For example, assume a widget is defined with a ui of 'alt action' and a uiCls of 'inner-el' on its innerElement reference element:

     Ext.define('Doodad', {
         extend: 'Ext.Widget',
         xtype: 'doodad',

         classCls: 'x-doodad',

         ui: 'alt action',

         element: {
             reference: 'element',

             children: [{
                 reference: 'innerElement',
                 cls: 'x-inner-el',
                 uiCls: 'inner-el'
             }]
         }
     });

This would result in the following markup when rendered:

<div class="x-doodad x-doodad-alt x-doodad-action">
    <div class="x-inner-el x-doodad-inner-el x-doodad-alt-inner-el x-doodad-action-inner-el"></div>
</div>

These additional classes can be used to style the reference element for a particular ui; however, use of uiCls is not typically necessary or recommended. Reference elements should usually be styled using simple descendant selectors:

.x-doodad-alt .x-inner-el {
    color: red;
}

When there is a possibility that widgets can be nested it is best to use direct child selectors to avoid the possibility of selecting all descendants instead of just the reference element for the intended widget:

.x-doodad-alt > .x-inner-el {
    color: red;
}

Only use uiCls when there is a possibility of nesting, AND there may be a variable number of elements between the main element and the reference element in question. For example, Ext.Container with docked items has a different number of elements in between its element and its bodyElement than a Container without docked items because of the wrapping elements that are dynamically added to support docking. To ensure it does not style all descendants it must use a uiCls to style its bodyElement:

.x-container-alt-body-el {
    background: #fff;
}

Note that when uiCls is specified it also adds a class name that does not contain the ui using just the classCls and/or baseCls as the prefix. This class name can be used for base-level styling that does not relate to any particular UI:

.x-container-body-el {
    position: relative;
}

Defaults to:

{
    reference: 'element'
}

enterAnimation : String / Mixed
deprecated dep

<ExtD3_treemap enterAnimation="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.enterAnimation = 'value';
let enterAnimation = element.enterAnimation;

Animation effect to apply when the Component is being shown. Typically you want to use an inbound animation type such as 'fadeIn' or 'slideIn'.

Defaults to:

null

Deprecated since version 2.0.0
Please use showAnimation instead.

eventHandlers : Object
deprecated dep private pri

<ExtD3_treemap eventHandlers="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.eventHandlers = { };
let eventHandlers = element.eventHandlers;

A map of event type to the corresponding handler method name. This is used internally by native event handling mechanism.

Defaults to:

{
    focus: 'handleFocusEvent',
    blur: 'handleBlurEvent'
}

Deprecated since version 6.6.0
Inline event handlers are deprecated

eventsSuspended
readonly ro private pri

<ExtD3_treemap eventsSuspended="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.eventsSuspended = 'value';
let eventsSuspended = element.eventsSuspended;

Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.

Defaults to:

0

exitAnimation : String / Mixed
deprecated dep

<ExtD3_treemap exitAnimation="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.exitAnimation = 'value';
let exitAnimation = element.exitAnimation;

Animation effect to apply when the Component is being hidden.

Defaults to:

null

Deprecated since version 2.0.0
Please use hideAnimation instead. Typically you want to use an outbound animation type such as 'fadeOut' or 'slideOut'.

expandEventName : String / String[]

<ExtD3_treemap expandEventName="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.expandEventName = 'value';
let expandEventName = element.expandEventName;

The expand event(s) to listen for on each node. The node in question will be expanded, if collapsed, or collapsed, if expanded. null can be used to prevent listening for the default event.

Defaults to:

'dblclick'

factoryConfig : Object
readonly ro

<ExtD3_treemap factoryConfig="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.factoryConfig = { };
let factoryConfig = element.factoryConfig;

If this property is specified by the target class of this mixin its properties are used to configure the created Ext.Factory.

flex : Number / String / Object

<ExtD3_treemap flex="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.flex = 'value';
let flex = element.flex;

The flex of this item if this item item is inside a Ext.layout.HBox or Ext.layout.VBox layout.

You can also update the flex of a component dynamically using the Ext.layout.FlexBox#setItemFlex method.

When supplied as a string or number this option supports the same syntax as CSS flex. For example:

flex: '1 2 auto'

sets flex-grow property to 0, flex-shrink to 2 and flex-basis to 'auto'.

The default flex-shrink value for box layout items is set to 0 in the stylesheet, which is different from the browser's default flex-shrink value of 1. This accommodates the majority use case for applications since where non-flexed components are typically not expected to shrink smaller than their default size.

For convenience when only a single number is supplied it is used as the value for both flex-grow and flex-shrink, for example flex: 3 is the same as flex: '3 3'

An object form is also accepted:

flex: {
    grow: 1,
    shrink: 2,
    basis: 'auto'
}

When the object form is supplied shrink always defaults to 0 regardless of the value of grow.

Although 'auto' is the default value for flex-basis, flex-basis defaults to 0% when flex is supplied as a single numeric or string value (e.g. flex: 1). If this behavior is not desired either explicitly set flex-basis to 'auto' or use the object form to set only grow and/or shrink:

flex: {
    grow: 2
}

Defaults to:

null

floatWrapCls : String
readonly ro private pri

<ExtD3_treemap floatWrapCls="value" />

The CSS class to add to this component's floatWrap when it's created.

Defaults to:

"x-float-wrap"

floated : Boolean

<ExtD3_treemap floated="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.floated = true;
let floated = element.floated;

A Component may be floated above all other components in the application. This means that the component is absolutely positioned, and will move to the front and occlude other sibling floated component if clicked.

A Floated component may have floated descendants. It will bring these decendants to the front with it when brought to the front of its sibling floated components.

By default, descendant floated components are all positioned using the viewport coordinate system. To make a floating component a positioning parent for descendants, and have the ancestors positioned relatively, configure the parent floated component with cfg-relative: true.

Defaults to:

false

Available since: 6.2.0

focusClsEl : Ext.dom.Element
readonly ro

<ExtD3_treemap focusClsEl="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.focusClsEl = 'value';
let focusClsEl = element.focusClsEl;

The element that will have the focusCls applied when component's focusEl is focused.

focusEl : Ext.dom.Element
readonly ro

<ExtD3_treemap focusEl="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.focusEl = 'value';
let focusEl = element.focusEl;

The element that will be focused when focus method is called on this component. Usually this is the same element that receives focus via mouse clicks, taps, and pressing Tab key.

Defaults to:

'el'

focusable : Boolean
readonly ro

<ExtD3_treemap focusable="true" />
let element = document.body.querySelector('ExtD3_treemap');
let focusable = element.focusable;

true for keyboard interactive Components or Widgets, false otherwise. For Containers, this property reflects interactiveness of the Container itself, not its children. See isFocusable.

Note: It is not enough to set this property to true to make a component keyboard interactive. You also need to make sure that the component's focusEl is reachable via Tab key (tabbable). See also tabIndex.

Defaults to:

false

fullscreen : Boolean
immutable imm

<ExtD3_treemap fullscreen="true" />
let element = document.body.querySelector('ExtD3_treemap');

Defaults to:

Ext.emptyFn

Returns

:Object

rect

x :  Number

y :  Number

width :  Number

height :  Number

getViewportRect
readonly ro protected pro

<ExtD3_treemap getViewportRect="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.getViewportRect = 'value';
let getViewportRect = element.getViewportRect;

hasFocus : Boolean
readonly ro

<ExtD3_treemap hasFocus="true" />

true if this component's focusEl is focused. See also containsFocus.

Defaults to:

false

hasListeners : Object
readonly ro

<ExtD3_treemap hasListeners="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
let hasListeners = element.hasListeners;

This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the Ext.app.EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.

The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:

 if (this.hasListeners.foo) {
     this.fireEvent('foo', this, arg1);
 }

height : Number / String

<ExtD3_treemap height="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.height = 'value';
let height = element.height;

The height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. By default, if this is not explicitly set, this Component's element will simply have its own natural size. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

hidden : Boolean

<ExtD3_treemap hidden="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.hidden = true;
let hidden = element.hidden;

Defaults to true for floated Components.

Defaults to:

null

hiddenParentLabels
readonly ro private pri

<ExtD3_treemap hiddenParentLabels="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.hiddenParentLabels = 'value';
let hiddenParentLabels = element.hiddenParentLabels;

A map of the {nodeId: Boolean} format, where the Boolean value controls visibility of the label.

Defaults to:

null

hideAnimation : String / Mixed

<ExtD3_treemap hideAnimation="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.hideAnimation = 'value';
let hideAnimation = element.hideAnimation;

Animation effect to apply when the Component is being hidden. Typically you want to use an outbound animation type such as 'fadeOut' or 'slideOut'. For more animations, check the Ext.fx.Animation#type config.

Defaults to:

null

hideMode : 'clip' / 'display' / 'offsets' / 'opacity' / 'visibility'

<ExtD3_treemap hideMode="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.hideMode = 'value';
let hideMode = element.hideMode;

A String which specifies how this component's DOM element will be hidden. The accepted values are any of these:

Hiding using display results in having no dimensions as well as resetting scroll positions to 0.

The other modes overcome this but may have different trade-offs in certain circumstances.

Defaults to:

'display'

Available since: 6.5.0

hideOnMaskTap : Boolean

<ExtD3_treemap hideOnMaskTap="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.hideOnMaskTap = true;
let hideOnMaskTap = element.hideOnMaskTap;

When using a modal Component, setting this to true will hide the modal mask and the Container when the mask is tapped on.

Defaults to:

null

hierarchyCls : String

<ExtD3_treemap hierarchyCls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.hierarchyCls = 'value';
let hierarchyCls = element.hierarchyCls;

html : String / Ext.dom.Element / HTMLElement

<ExtD3_treemap html="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.html = 'value';

Defaults to:

null

id : String
immutable imm

<ExtD3_treemap id="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.id = 'value';
let id = element.id;

The unique id of this component instance.

It should not be necessary to use this configuration except for singleton objects in your application. Components created with an id may be accessed globally using Ext.getCmp.

Instead of using assigned ids, use the itemId config, and Ext.ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The <ExtContainer/> class contains shortcut methods to query its descendant Components by selector.

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Note: to avoid complications imposed by a unique id also see itemId.

Defaults to an auto-assigned id.

inheritUi : Boolean / String
readonly ro

<ExtD3_treemap inheritUi="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.inheritUi = true;
let inheritUi = element.inheritUi;

Set to true on widgets that should inherit ui from their parent container. This property is typically set on the class body, but can be set on an instance as long as it is set prior to the instance being added to its container. This property is inspected at the moment a widget is added to a container, and any UIs on the container are added to the widget at that time. Inherited UIs are in addition to the widget's own ui, and are updated when the container's UI changes.

Defaults to:

false

initFocusable
readonly ro protected pro

<ExtD3_treemap initFocusable="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.initFocusable = 'value';
let initFocusable = element.initFocusable;

Defaults to:

Ext.emptyFn

instanceCls : String / String[]

interactions

<ExtD3_treemap interactions="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.interactions = 'value';
let interactions = element.interactions;

The list of interaction configs for this D3 component. D3 package interactions are very simular to native D3 behaviors. However, D3 behaviors (and its event system), are incompatible with ExtJS event system. D3 package interactions may also support certain features that D3 behaviors lack, like kinetic scrolling, elastic borders and scroll indicators (see the Ext.d3.interaction.PanZoom interaction for more information).

Defaults to:

[]

isComponent
readonly ro private pri

<ExtD3_treemap isComponent="value" />
let element = document.body.querySelector('ExtD3_treemap');

Defaults to:

false

Available since: 5.0.0

isFirstInstance : Boolean
readonly ro protected pro

<ExtD3_treemap isFirstInstance="true" />
let element = document.body.querySelector('ExtD3_treemap');
let isFirstInstance = element.isFirstInstance;

This property is set to true if this instance is the first of its class.

Defaults to:

false

Available since: 5.0.0

isInner
readonly ro private pri

<ExtD3_treemap isInner="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.isInner = 'value';
let isInner = element.isInner;

Defaults to:

true

isInstance : Boolean
readonly ro protected pro

This value is true and is used to identify plain objects from instances of a defined class.

Defaults to:

true

isLayoutBlocked
readonly ro private pri

<ExtD3_treemap isLayoutBlocked="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.isLayoutBlocked = 'value';
let isLayoutBlocked = element.isLayoutBlocked;

Defaults to:

Ext.emptyFn

isObservable : Boolean
readonly ro

<ExtD3_treemap isObservable="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.isObservable = true;
let isObservable = element.isObservable;

true in this class to identify an object as an instantiated Observable, or subclass thereof.

Defaults to:

true

itemId : String

<ExtD3_treemap itemId="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.itemId = 'value';
let itemId = element.itemId;

An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with Ext#getCmp, use itemId with Ext.Container#getComponent which will retrieve itemId's or ids. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container - avoiding potential conflicts with Ext.ComponentManager which requires a unique id.

Also see id, Ext.Container#query, Ext.Container#down and Ext.Container#child.

Defaults to:

undefined

keyMap : Object

<ExtD3_treemap keyMap="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.keyMap = { };
let keyMap = element.keyMap;

An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.

The handler descriptor can be simply the handler function(either the literal function or the method name), or it can be an object with these properties:

  • handler: The function or its name to call to handle the event.
  • scope: The this pointer context (can be "this" or "controller").
  • event: An optional override of the key event to which to listen.

Important: Calls to setKeyMap do not replace the entire keyMap but instead update the provided mappings. That is, unless null is passed as the value of the keyMap which will clear the keyMap of all entries.

Defaults to:

null

Properties

scope : String

The default scope to apply to key handlers which do not specify a scope. This is processed the same way as the scope of cfg-listeners. It defaults to the "controller", but using 'this' means that an instance method will be used.

keyMapEnabled : Boolean

<ExtD3_treemap keyMapEnabled="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.keyMapEnabled = true;
let keyMapEnabled = element.keyMapEnabled;

Enables or disables processing keys in the keyMap. This value starts as null and if it is null when initKeyMap is called, it will automatically be set to true. Since initKeyMap is called by <ExtComponent/> at the proper time, this is not something application code normally handles.

Defaults to:

null

keyMapTarget : String
immutable imm protected pro

<ExtD3_treemap keyMapTarget="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.keyMapTarget = 'value';
let keyMapTarget = element.keyMapTarget;

The name of the member that should be used to listen for keydown/keypress events. This is intended to be controlled at the class level not per instance.

Defaults to:

'el'

labelQuantizer
readonly ro private pri

The padding used to separate a node’s adjacent children.

Defaults to: 0

label : Object

Child tile label options.

offset :  Number[] (optional)

The offset of the label from the top-left corner of the tile's rect. Defaults to [5, 1].

left : Number / String

<ExtD3_treemap left="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.left = 'value';
let left = element.left;

The absolute left position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

linkKey : Function

<ExtD3_treemap linkKey="function() { }" />
let element = document.body.querySelector('ExtD3_treemap');
element.linkKey(link, index);

The key function for links. Returns the 'id' of the link's target Ext.data.TreeModel by default.

listeners : Object

<ExtD3_treemap listeners="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.listeners = { };
let listeners = element.listeners;

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.

DOM events from Ext JS <ExtComponent/>

While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually only done when extra value can be added. For example the DataViews itemclick event passing the node clicked on. To access DOM events directly from a child element of a Component, we need to specify the element option to identify the Component property to add a DOM listener to:

new Ext.panel.Panel({
    width: 400,
    height: 200,
    dockedItems: [{
        xtype: 'toolbar'
    }],
    listeners: {
        click: {
            element: 'el', //bind to the underlying el property on the panel
            fn: function(){ console.log('click el'); }
        },
        dblclick: {
            element: 'body', //bind to the underlying body property on the panel
            fn: function(){ console.log('dblclick body'); }
        }
    }
});

margin : Number / String

<ExtD3_treemap margin="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.margin = 'value';
let margin = element.margin;

The margin to use on this Component. Can be specified as a number (in which case all edges get the same margin) or a CSS string like '5 10 10 10'

Defaults to:

null

maxHeight : Number / String

<ExtD3_treemap maxHeight="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.maxHeight = 'value';
let maxHeight = element.maxHeight;

The maximum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size. Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)

Defaults to:

null

maxWidth : Number / String

<ExtD3_treemap maxWidth="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.maxWidth = 'value';
let maxWidth = element.maxWidth;

The maximum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size. Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)

Defaults to:

null

minHeight : Number / String

<ExtD3_treemap minHeight="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.minHeight = 'value';
let minHeight = element.minHeight;

The minimum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

modal : Boolean

<ExtD3_treemap modal="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.modal = true;
let modal = element.modal;

true to make this Component modal. This will create a mask underneath the Component that covers its parent and does not allow the user to interact with any other Components until this Component is dismissed.

Defaults to:

null

modelValidation : Boolean
immutable imm

<ExtD3_treemap modelValidation="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.modelValidation = true;
let modelValidation = element.modelValidation;

This config enables binding to your Ext.data.Model#validators. This is only processed by form fields (e.g., Ext.field.*) at present, however, this setting is inherited and so can be set on a parent container.

When set to true by a component (or by an ancestor container), the validators of for any {@Ext.data.Model record} fields will be used wherever the value is bound to such data fields.

While this config can be set arbitrarily high in the component hierarchy, doing so can create a lot overhead if most of your form fields do not actually rely on validators in your data model.

Using this setting for a form that is bound to an Ext.data.Model might look like this:

 {
     xtype: 'panel',
     modelValidation: true,
     items: [{
         xtype: 'textfield',
         bind: '{theUser.firstName}'
     },{
         xtype: 'textfield',
         bind: '{theUser.lastName}'
     },{
         xtype: 'textfield',
         bind: '{theUser.phoneNumber}'
     },{
         xtype: 'textfield',
         bind: '{theUser.email}'
     }]
 }

Defaults to:

function(record) {
    return record.isExpanded() ? record.childNodes : null;
}

Parameters

record :  Ext.data.TreeModel

An instance of the TreeModel class.

Returns

:Ext.data.TreeModel[]

nodeClass : Function

<ExtD3_treemap nodeClass="function() { }" />
let element = document.body.querySelector('ExtD3_treemap');

  • x-d3-parent - if a node is a parent node;
  • x-d3-leaf - if a node is a leaf node;
  • x-d3-expanded - if a node is expanded;
  • x-d3-root - if a node is the root node (represents the root of the store);
  • x-d3-layout-root - if a node is the root node of the current layout.

Defaults to:

undefined

Parameters

selection :  d3.selection

nodeClassCfg
readonly ro private pri

<ExtD3_treemap nodeClassCfg="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.nodeClassCfg = 'value';
let nodeClassCfg = element.nodeClassCfg;

Cached config used by defaultNodeClass. For example:

    root: function (node) { return node.data.isRoot(); },
}

Defaults to:

null

nodeKey : Function

<ExtD3_treemap nodeKey="function() { }" />
let element = document.body.querySelector('ExtD3_treemap');
element.nodeKey(node, index);

The key function for nodes. Returns the 'id' of the node's Ext.data.TreeModel by default.

Defaults to:

function(node, index) {
    return node.data.id;
}

Parameters

node :  d3.hierarchy

index :  Number

Returns

:String

nodeText : Function / String / String[]

<ExtD3_treemap nodeText="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.nodeText(component, node);

A function that returns a text string, given a component and node (d3.hierarchy) instance. Alternatively, can be a field name or an array of field names used to fetch the text. If array of field names is given, the first non-empty string will be used. A node holds a reference to the Ext.data.TreeModel instance in its data field. For example, to return the value of the record's field name as node's text the following function can be used:

nodeText: function (component, node) {
    var record = node.data,
        text = record.get('name');

    return text;
}

Or simply:

nodeText: 'name'

To return the value of the title field, if the name field is empty:

nodeText: ['name', 'title']

[
    'name',
    'text'
]

Parameters

component :  Ext.d3.hierarchy.Hierarchy

node :  d3.hierarchy

    });
}

Parameters

selection :  d3.selection

nodeValue : Function / String / Number

<ExtD3_treemap nodeValue="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.nodeValue(record);

The function that receives the node's data (tree store record) and returns the numeric value of the node. This config can also be a field name or a number, in which case it will be converted to a function that returns the value of the specified field, or a function that returns the given number for all nodes. Note: nodeChildren does not have effect on this config, even though only expanded nodes will render by default, the nodeValue function will be called for all nodes.

Defaults to:

1

Parameters

record :  Ext.data.TreeModel

The data of the node (store record).

Returns

:Number

Numeric value of the node used to calculate its area.

            40
        ]
    }
}

Properties

plugins : Array / Ext.enums.Plugin / Object / Ext.plugin.Abstract

<ExtD3_treemap plugins="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.plugins = { };
let plugins = element.plugins;

This config describes one or more plugin config objects used to create plugin instances for this component.

Plugins are a way to bundle and reuse custom functionality. Plugins should extend Ext.plugin.Abstract but technically the only requirement for a valid plugin is that it contain an init method that accepts a reference to its owner. Once a plugin is created, the owner will call the init method, passing a reference to itself. Each plugin can then call methods or respond to events on its owner as needed to provide its functionality.

This config's value can take several different forms.

The value can be a single string with the plugin's Ext.enums.Plugin:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: 'listpaging'
 });

In the above examples, the string "listpaging" is the type alias for listpaging. The full alias includes the "plugin." prefix (i.e., 'plugin.listpaging').

The preferred form for multiple plugins or to configure plugins is the keyed-object form (new in version 6.5):

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: {
         pullrefresh: true,
         listpaging: {
             autoPaging: true,
             weight: 10
         }
     }
 });

The object keys are the id's as well as the default type alias. This form allows the value of the plugins to be merged from base class to derived class and finally with the instance configuration. This allows classes to define a set of plugins that derived classes or instantiators can further configure or disable. This merge behavior is a feature of the config.

The plugins config can also be an array of plugin aliases (arrays are not merged so this form does not respect plugins defined by the class author):

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

An array can also contain elements that are config objects with a type property holding the type alias:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['pullrefresh', {
         type: 'listpaging',
         autoPaging: true
     }]
 });

Defaults to:

null

positioned
readonly ro private pri

<ExtD3_treemap positioned="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.positioned = 'value';
let positioned = element.positioned;

Defaults to:

false

publishes : String / String[] / Object

<ExtD3_treemap publishes="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.publishes = 'value';
let publishes = element.publishes;

One or more names of config properties that this component should publish to its ViewModel. Generally speaking, only properties defined in a class config block (including ancestor config blocks and mixins) are eligible for publishing to the viewModel. Some components override this and publish their most useful configs by default.

Note: We'll discuss publishing properties not found in the config block below.

Values determined to be invalid by component (often form fields and model validations) will not be published to the ViewModel.

This config uses the cfg-reference to determine the name of the data object to place in the ViewModel. If reference is not set then this config is ignored.

By using this config and cfg-reference you can bind configs between components. For example:

 ...
     items: [{
         xtype: 'textfield',
         reference: 'somefield',  // component's name in the ViewModel
         publishes: 'value' // value is not published by default
     },{
         ...
     },{
         xtype: 'displayfield',
         bind: 'You have entered "{somefield.value}"'
     }]
 ...

Classes must provide this config as an Object:

 Ext.define('App.foo.Bar', {
     publishes: {
         foo: true,
         bar: true
     }
 });

This is required for the config system to properly merge values from derived classes.

For instances this value can be specified as a value as show above or an array or object as follows:

 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: [
         'value',
         'rawValue',
         'dirty'
     ]
 }

 // This achieves the same result as the above array form.
 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: {
         value: true,
         rawValue: true,
         dirty: true
     }
 }

In some cases, users may want to publish a property to the viewModel that is not found in a class config block. In these situations, you may utilize publishState if the property has a setter method. Let's use setFieldLabel as an example:

  setFieldLabel: function(fieldLabel) {
      this.callParent(arguments);
      this.publishState('fieldLabel', fieldLabel);
  }

With the above chunk of code, fieldLabel may now be published to the viewModel.

Defaults to:

'selection'

record : Ext.data.Model

<ExtD3_treemap record="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.record = 'value';
let record = element.record;

A model instance which updates the Component's html based on it's tpl. Similar to the data configuration, but tied to to a record to make allow dynamic updates. This must be a model instance and not a configuration of one.

Defaults to:

null

reference : String
immutable imm

<ExtD3_treemap reference="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.reference = 'value';
let reference = element.reference;

Specifies a name for this component inside its component hierarchy. This name must be unique within its view or its Ext.app.ViewController. See the documentation in Ext.container.Container for more information about references.

Note: Valid identifiers start with a letter or underscore and are followed by zero or more additional letters, underscores or digits. References are case sensitive.

Defaults to:

null

relative : Boolean

<ExtD3_treemap relative="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.relative = true;
let relative = element.relative;

Only valid when a component is cfg-floated

Configure this as true if you require descendant floated components to be positioned relative to this component's coordinate space, not the viewport's coordinate space.

Note: The coordinate space is this Component's encapsulating element's area. Not that of the inner element in which static child items are rendered by the layout.

Defaults to:

false

Available since: 6.2.0

rendered : Boolean
readonly ro

<ExtD3_treemap rendered="true" />
let element = document.body.querySelector('ExtD3_treemap');
let rendered = element.rendered;

The rendered flag is set when a widget is inserted into the document for the first time.

Note that this is a one-way operation. The first time a widget is inserted into the document, this flag is set, and it is never unset.

right : Number / String

<ExtD3_treemap right="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.right = 'value';
let right = element.right;

The absolute right position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

ripple : Boolean / Object / String

<ExtD3_treemap ripple="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.ripple = true;
let ripple = element.ripple;

Set to truthy, Color or Object value for the ripple.

Defaults to:

null

Available since: 6.5.0

Properties

color : String

The background color of the ripple.

position : Array

Position for the ripple to start at [x,y]. Determines if a Ripple effect should happen whenever this element is pressed.

For example: { ripple: true }

Or:

 {
     ripple: {
         color: 'red'
     }
 }

For complex components, individual elements can suppress ripples by adding the x-no-ripple class to disable rippling for a tree of elements.

element.scaleLabels = true;
let scaleLabels = element.scaleLabels;

If true the bigger tiles will have (more or less) proportionally bigger labels.

Defaults to:

false

Available since: 6.5.0

scene
readonly ro private pri

<ExtD3_treemap scene="value" />
let element = document.body.querySelector('ExtD3_treemap');

scrollable : Boolean / String / Object

<ExtD3_treemap scrollable="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.scrollable = true;
let scrollable = element.scrollable;

Configuration options to make this Component scrollable. Acceptable values are:

  • true to enable auto scrolling.
  • false (or null) to disable scrolling - this is the default.
  • x or horizontal to enable horizontal scrolling only
  • y or vertical to enable vertical scrolling only

Also accepts a configuration object for a Ext.scroll.Scroller if if advanced configuration is needed.

The getter for this config returns the Ext.scroll.Scroller instance. You can use the Scroller API to read or manipulate the scroll position:

// scrolls the component to 5 on the x axis and 10 on the y axis
component.getScrollable().scrollTo(5, 10);

Defaults to:

null

selectEventName : String / String[]

<ExtD3_treemap selectEventName="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.selectEventName = 'value';
let selectEventName = element.selectEventName;

The select event(s) to listen for on each node. The node in question will be selected, selection will be removed from the previously selected node. The select event won't be handled when Ctrl/Cmd is pressed. For example, this allows to expand a node by double-clicking without selecting it. null can be used to prevent listening for the default event.

Defaults to:

'click'

selection : Ext.data.TreeModel

<ExtD3_treemap selection="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.selection = 'value';

<ExtD3_treemap self="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.self = 'value';
let self = element.self;

Get the reference to the current class from which this object was instantiated. Unlike Ext.Base#statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See Ext.Base#statics for a detailed comparison

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); // dependent on 'this'
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
    }

        if (!component.size) {
            // set things up
        } else {
            // handle resize
        }
    }
}

stateful : Boolean / Object / String[]

<ExtD3_treemap stateful="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.stateful = true;
let stateful = element.stateful;

This config specifies the config properties that will be persisted using the Ext.state.Provider. If this config is set to true, the configs specified by statefulDefaults will be assumed.

 stateful: true

Otherwise, this config can be an array of strings of the properties to save:

 stateful: [
     'width',
     'height',
     'collapsed'
 ]

The above is equivalent to:

 stateful: {
     width: true,
     height: true,
     collapsed: true
 }

Note: To be truly stateful, an id or stateId must also be assigned.

A stateful object will save its state when any of these config properties change value.

Defaults to:

false

statefulDefaults : Object / String[]
protected pro

<ExtD3_treemap statefulDefaults="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.statefulDefaults = 'value';
let statefulDefaults = element.statefulDefaults;

The default set of stateful properties. The form of this config is the same as stateful except this config cannot be a Boolean.

This config is intended for classes to specify so that instances can simply enable statefulness using stateful: true.

Defaults to:

null

store : Ext.data.Store

<ExtD3_treemap store="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.store = 'value';

Additional CSS styles that will be rendered into an inline style attribute when the widget is rendered.

You can pass either a string syntax:

style: 'background:red'

Or by using an object:

style: {
    background: 'red'
}

When using the object syntax, you can define CSS Properties by using a string:

style: {
    'border-left': '1px solid red'
}

Although the object syntax is much easier to read, we suggest you to use the string syntax for better performance.

Defaults to:

null

svg
readonly ro private pri

<ExtD3_treemap svg="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.svg = 'value';
let svg = element.svg;

See getSvg.

Defaults to:

null

tabIndex : Number

<ExtD3_treemap tabIndex="10" />
let element = document.body.querySelector('ExtD3_treemap');
element.tabIndex = 10;
let tabIndex = element.tabIndex;

DOM tabIndex attribute for this component's focusEl.

Defaults to:

null

template : Array
readonly ro protected pro

<ExtD3_treemap template="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.template = 'value';
let template = element.template;

An array of child elements to use as the children of the main element in the element template. Only used if "children" are not specified explicitly in the element template.

Defaults to:

Defaults to:

true

tooltip : String / Object

<ExtD3_treemap tooltip="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.tooltip = 'value';
let tooltip = element.tooltip;

The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or <ExtTooltip/> config object.

The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.

To force a unique tooltip instance to be created, specify autoCreate: true on this configuration.

Configuring this with autoHide: false implies autoCreate: true so that the desired persistent behavior can be obtained with other targets still showing the singleton instance.

Defaults to:

null

top : Number / String

<ExtD3_treemap top="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.top = 'value';
let top = element.top;

The absolute top position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

touchAction : Object

<ExtD3_treemap touchAction="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.touchAction = { };
let touchAction = element.touchAction;

Emulates the behavior of the CSS touch-action property in a cross-browser compatible manner.

Keys in this object are touch action names, and values are false to disable a touch action or true to enable it. Accepted keys are:

  • panX
  • panY
  • pinchZoom
  • doubleTapZoom

All touch actions are enabled (true) by default, so it is usually only necessary to specify which touch actions to disable. For example, the following disables only horizontal scrolling and pinch-to-zoom on the component's main element:

touchAction: {
    panX: false,
    pinchZoom: false
}

Touch actions can be specified on reference elements using the reference element name, for example:

// disables horizontal scrolling on the main element, and double-tap-zoom
// on the child element named "body"
touchAction: {
    panY: false
    body: {
        doubleTapZoom: false
    }
}

The primary motivation for setting the touch-action of an element is to prevent the browser's default handling of a gesture such as pinch-to-zoom, or drag-to-scroll, so that the application can implement its own handling of that gesture on the element. Suppose, for example, a component has a custom drag handler on its element and wishes to prevent horizontal scrolling of its container while it is being dragged:

Ext.create('Ext.Widget', {
    touchAction: {
        panX: false
    },
    listeners: {
        drag: function(e) {
            // implement drag logic
        }
    }
});

Defaults to:

null

tpl : String / String[] / Ext.Template / Ext.XTemplate[]

<ExtD3_treemap tpl="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.tpl = 'value';
let tpl = element.tpl;

A String, Ext.Template, Ext.XTemplate or an Array of strings to form an Ext.XTemplate. Used in conjunction with the data and tplWriteMode configurations.

Note The data configuration must be set for any content to be shown in the component when using this configuration.

Defaults to:

null

tplWriteMode : String

<ExtD3_treemap tplWriteMode="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.tplWriteMode = 'value';
let tplWriteMode = element.tplWriteMode;

The Ext.(X)Template method to use when updating the content area of the Component.

Valid modes are:

  • append
  • insertAfter
  • insertBefore
  • insertFirst
  • overwrite

Defaults to:

'overwrite'

transitions

<ExtD3_treemap transitions="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.transitions = 'value';
let transitions = element.transitions;

A map of transition configs. For example:

transitions: {
    select: {
        duration: 500,
        ease: 'cubicInOut'
    },
    zoom: {
        name: 'zoom',
        duration: 1000
    },
    ...
}

A class would define the defaults for its transitions, and a user only needs to set the transitions config of an instance to disable a transition, e.g.:

transitions: {
    // transitions are enabled by default, `true` should never be used here
    select: false
}

or alter its config:

transitions: {
    select: {
        // the `duration` stays the same,
        // only the easing function is altered
        ease: 'bounceOut'
    }
}

The transitions defined this way are merely configs. To create an actual transition from one of these configs, use the createTransition method. For example:

this.createTransition('select')

A transition object can optionally specify a name, if it's different from the key in the transitions config. For example:

transitions: {
    layout: {
        name: 'foo',
        duration: 500
    }
}

Otherwise the name will be set automatically, for example:

transition.name = this.getId() + '-' + key

Transition names (whether explicitly given or not) are prefixed by component ID to prevent transitions with the same name but on a different component from cancelling each other out.

However, transitions with the same name on the same component will still cancel each other out, if created via createTransition on the same selection or with no selection provided.

duration, ease and name properties of transition objects in this config are reserved, and will be used to configure a d3.transition instance. However, transition objects may also have other properties that are related to this transition. For example:

transitions: {
    select: {
        duration: 500,
        ease: 'cubicInOut',
        targetScale: 1.1
    }
}

The targetScale property here won't be consumed by a d3.transition instance; instead a component can make use of it in whichever way it sees fit to animate the selected element.

Defaults to:

{
    layout: {
        duration: 500,
        ease: 'cubicInOut'
    },
    select: {
        duration: 150,
        // 300ms total (scale up + scale down)
        ease: 'cubicInOut',
        sourceScale: 1,
        targetScale: 1.07
    }
}

translatable : Object
private pri

<ExtD3_treemap translatable="{ }" />
let element = document.body.querySelector('ExtD3_treemap');

Defaults to:

null

twoWayBindable : String / String[] / Object

<ExtD3_treemap twoWayBindable="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.twoWayBindable = 'value';
let twoWayBindable = element.twoWayBindable;

This object holds a map of config properties that will update their binding as they are modified. For example, value is a key added by form fields. The form of this config is the same as publishes.

This config is defined so that updaters are not created and added for all bound properties since most cannot be modified by the end-user and hence are not appropriate for two-way binding.

Defaults to:

null

ui : String / String[]

<ExtD3_treemap ui="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.ui = 'value';
let ui = element.ui;

The ui or uis to be used on this Component

When a ui is configured, CSS class names are added to the element, created by appending the ui name(s) to each classCls and/or baseCls.

Defaults to:

null

uiReferences : Object
readonly ro private pri

<ExtD3_treemap uiReferences="{ }" />
let element = document.body.querySelector('ExtD3_treemap');
element.uiReferences = { };
let uiReferences = element.uiReferences;

A map that tracks all reference elements configured with a uiCls. Contains the element reference by default since the element always gets non-suffixed ui-specific CSS class names added to it (see syncUiCls)

updateNodes
readonly ro protected pro

<ExtD3_treemap updateNodes="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.updateNodes(selection);

Defaults to:

Ext.emptyFn

Parameters

selection :  d3.selection

The update selection for nodes.

userCls : String / String[]

<ExtD3_treemap userCls="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.userCls = 'value';
let userCls = element.userCls;

One or more CSS classes to add to the component's primary element. This config is intended solely for use by the component instantiator (the "user"), not by derived classes.

For example:

 items: [{
     xtype: 'button',
     userCls: 'my-button'
 ...
 }]

Defaults to:

null

userSelectable : Boolean / String / Object

<ExtD3_treemap userSelectable="true" />
let element = document.body.querySelector('ExtD3_treemap');
element.userSelectable = true;
let userSelectable = element.userSelectable;

Setting the value to true implies auto, while false implies none. Setting the value to text allows users to select text within this component. The value may also be an object keyed by child element name as seen below.

Can also be any valid value for the CSS3 user-select property.

By default, the user cannot click+drag+select text/elements of the UI. Applications may want to enable user selection for specific DOM elements, such as the bodyElement of a component used as a tab panel. The tab and tab text would not be user selectable in this example, but the content area when the tab is selected would.

 userSelectable: {
     element: true,       // allow the element to be user selectable
     bodyElement: true    // allow the component's body element to be user selectable
 }

Defaults to:

false

Available since: 6.5.1

userSelectableClsMap
readonly ro private pri

<ExtD3_treemap userSelectableClsMap="value" />
let element = document.body.querySelector('ExtD3_treemap');

let userSelectableClsMap = element.userSelectableClsMap;

Defaults to:

{
    "true": Ext.baseCSSPrefix + 'user-selectable-auto',
    "false": Ext.baseCSSPrefix + 'user-selectable-none',
    all: Ext.baseCSSPrefix + 'user-selectable-all',
    auto: Ext.baseCSSPrefix + 'user-selectable-auto',
    text: Ext.baseCSSPrefix + 'user-selectable-text',
    none: Ext.baseCSSPrefix + 'user-selectable-none'
}

readonly ro private pri

<ExtD3_treemap validRefRe="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.validRefRe = 'value';
let validRefRe = element.validRefRe;

Regular expression used for validating reference values.

Defaults to:

/^[a-z_][a-z0-9_]*$/i

viewModel : String / Object / Ext.app.ViewModel

<ExtD3_treemap viewModel="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.viewModel = 'value';
let viewModel = element.viewModel;

The ViewModel is a data provider for this component and its children. The data contained in the ViewModel is typically used by adding bind configs to the components that want present or edit this data.

When set, the ViewModel is created and links to any inherited viewModel instance from an ancestor container as the "parent". The ViewModel hierarchy, once established, only supports creation or destruction of children. The parent of a ViewModel cannot be changed on the fly.

If this is a root-level ViewModel, the data model connection is made to this component's associated Ext.data.Session. This is determined by calling getInheritedSession.

Defaults to:

null

weight : Number

<ExtD3_treemap weight="10" />
let element = document.body.querySelector('ExtD3_treemap');
element.weight = 10;
let weight = element.weight;

This value controls this item's order in a weighted <ExtContainer/> (see parent).

Lower values gravitate towards the start of the container - the top in vertical layouts, the locale start side in horizontal layouts.

Defaults to:

0

width : Number / String

<ExtD3_treemap width="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.width = 'value';
let width = element.width;

The width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. By default, if this is not explicitly set, this Component's element will simply have its own natural size. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

wrapper
readonly ro private pri

<ExtD3_treemap wrapper="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.wrapper = 'value';
let wrapper = element.wrapper;

The padding and clipping is applied to the scene's wrapper element, not to the scene itself. See getWrapper.

Defaults to:

null

x : Number

<ExtD3_treemap x="10" />
let element = document.body.querySelector('ExtD3_treemap');
element.x = 10;
let x = element.x;

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Defaults to:

0

xtype : String
immutable imm

<ExtD3_treemap xtype="value" />
let element = document.body.querySelector('ExtD3_treemap');
element.xtype = 'value';
let xtype = element.xtype;

The xtype configuration option can be used to optimize Component creation and rendering. It serves as a shortcut to the full component name. For example, the component Ext.button.Button has an xtype of button.

You can define your own xtype on a custom <ExtComponent/> like so:

Ext.define('PressMeButton', {
    extend: 'Ext.button.Button',
    xtype: 'pressmebutton',
    text: 'Press Me'
});

Any Component can be created implicitly as an object config with an xtype specified, allowing it to be declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources until they are actually needed. In complex, nested layouts containing many Components, this can make a noticeable improvement in performance.

// Explicit creation of contained Components:
var panel = new Ext.Panel({
   // ...
   items: [
      Ext.create('Ext.button.Button', {
         text: 'OK'
      })
   ]
});

// Implicit creation using xtype:
var panel = new Ext.Panel({
   // ...
   items: [{
      xtype: 'button',
      text: 'OK'
   }]
});

In the first example, the button will always be created immediately during the panel's initialization. With many added Components, this approach could potentially slow the rendering of the page. In the second example, the button will not be created or rendered until the panel is actually displayed in the browser. If the panel is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and will never consume any resources whatsoever.

y : Number

<ExtD3_treemap y="10" />
let element = document.body.querySelector('ExtD3_treemap');
element.y = 10;
let y = element.y;

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Defaults to:

0

zIndex : Number

<ExtD3_treemap zIndex="10" />
let element = document.body.querySelector('ExtD3_treemap');
element.zIndex = 10;
let zIndex = element.zIndex;

The z-index to give this Component when it is rendered.

Not valid for cfg-floated Components. The Z ordering of cfg-floated Components is managed by ordering of the DOM elements.

:Ext.dom.Element

addElementReferenceOnDemand ( name, domNode )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.addElementReferenceOnDemand(name, domNode);

Reduces instantiation time for a Widget by lazily instantiating Ext.Element references the first time they are used. This optimization only works for elements with no listeners specified.

Parameters

name :  String

The name of the reference

domNode :  HTMLElement

addListener ( eventName, [fn], [scope], [options], [order] ) : Object
chainable ch

let element = document.body.querySelector('ExtD3_treemap');
let addListener = element.addListener(eventName, fn, scope, options, order);

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  String/Object

The name of the event to listen for. May also be an object who's property names are event names.

fn :  Function/String (optional)

The method the event invokes or the name of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#fireEvent plus the options parameter described below.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

An object containing handler configuration.

Note: The options object will also be passed as the last argument to every event handler.

This object may contain any of the following properties:

scope :  Object

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean

True to add a handler to handle just the next firing of the event, and then remove itself.

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to <ExtComponent/>. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of <ExtComponent/> which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
      title: 'The title',
      listeners: {
          click: this.handlePanelClick,
          element: 'body'
      }
  });

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional set of arguments to pass to the handler function before the actual fired event arguments. For example, if args is set to ['foo', 42], the event handler function will be called with an arguments list like this:

 handler('foo', 42, <actual event arguments>...);

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

Defaults to: 'current'

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners =  = myButton.on({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

addManagedListener ( item, ename, [fn], [scope], [options] ) : Object

let element = document.body.querySelector('ExtD3_treemap');
let addManagedListener = element.addManagedListener(item, ename, fn, scope, options);

The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function/String (optional)

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

options :  Object (optional)

If the ename parameter was an event name, this is the addListener options.

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners = myButton.mon({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

addNodeListener ( eventName, handler )

     type: 'pullrefresh',
     pullRefreshText: 'Pull to refresh...'
 });

Available since: 6.2.0

afterEdit
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.afterEdit();

Used to handle joining of a record to a tpl

afterErase
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.afterErase();

Used to handle joining of a record to a tpl

afterRender
template tpl

let element = document.body.querySelector('ExtD3_treemap');
element.afterRender();

This method is called after the component is initially added to the DOM. If this component <ExtContainer/> other components, the afterRender method for child components is called before the parent's afterRender.

Implementations of this method should avoid reading from the DOM but are free to write to the DOM as needed. To read the DOM, consider implementing onRender instead.

This method is not generally needed because components always have their own DOM element and these are maintained by config property updaters prior to insertion in the DOM. In general, it is always best to manipulate the component's elements outside the DOM where there is no associated reflow or layout cost. This method is useful for situations where the component's elements must be in the DOM in order to be manipulated correctly.

Available since: 6.5.0

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callOverridden();

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

:Object

Returns the result of calling the overridden method

Deprecated since version 4.1.0
Use method-callParent instead.

callParent ( args ) : Object
protected pro

let element = document.body.querySelector('ExtD3_treemap');
let callParent = element.callParent(args);

Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext#define).

 Ext.define('My.Base', {
     constructor: function(x) {
         this.x = x;
     },

     statics: {
         method: function(x) {
             return x;
         }
     }
 });

 Ext.define('My.Derived', {
     extend: 'My.Base',

     constructor: function() {
         this.callParent([21]);
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // alerts 21

This can be used with an override as follows:

 Ext.define('My.DerivedOverride', {
     override: 'My.Derived',

     constructor: function(x) {
         this.callParent([x*2]); // calls original My.Derived constructor
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // now alerts 42

This also works with static and private methods.

 Ext.define('My.Derived2', {
     extend: 'My.Base',

     // privates: {
     statics: {
         method: function(x) {
             return this.callParent([x*2]); // calls My.Base.method
         }
     }
 });

 alert(My.Base.method(10));     // alerts 10
 alert(My.Derived2.method(10)); // alerts 20

Lastly, it also works with overridden static methods.

 Ext.define('My.Derived2Override', {
     override: 'My.Derived2',

     // privates: {
     statics: {
         method: function(x) {
             return this.callParent([x*2]); // calls My.Derived2.method
         }
     }
 });

 alert(My.Derived2.method(10); // now alerts 40

To override a method and replace it and also call the superclass method, use method-callSuper. This is often done to patch a method to fix a bug.

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

:Object

Returns the result of calling the parent method

callSuper ( args ) : Object
protected pro

let element = document.body.querySelector('ExtD3_treemap');
let callSuper = element.callSuper(args);

This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.

Consider:

 Ext.define('Ext.some.Class', {
     method: function() {
         console.log('Good');
     }
 });

 Ext.define('Ext.some.DerivedClass', {
     extend: 'Ext.some.Class',

     method: function() {
         console.log('Bad');

         // ... logic but with a bug ...

         this.callParent();
     }
 });

To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an override:

 Ext.define('App.patches.DerivedClass', {
     override: 'Ext.some.DerivedClass',

     method: function() {
         console.log('Fixed');

         // ... logic but with bug fixed ...

         this.callSuper();
     }
 });

The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callSuper(arguments)

Returns

:Object

Returns the result of calling the superclass method

The selection to create this transition on.

Returns

:d3.transition

destroy

let element = document.body.querySelector('ExtD3_treemap');
element.destroy();

Destroys the Widget. This method should not be overridden in custom Widgets, because it sets the flags and does final cleanup that must go last. Instead, override doDestroy method to add functionality at destruction time.

destroyMembers ( args )

let element = document.body.querySelector('ExtD3_treemap');
element.destroyMembers(args);

Destroys member properties by name.

If a property name is the name of a config, the getter is not invoked, so if the config has not been initialized, nothing will be done.

The property will be destroyed, and the corrected name (if the property is a config and config names are prefixed) will set to null in this object's dictionary.

Parameters

args :  String...

One or more names of the properties to destroy and remove from the object.

destroyPlugin ( plugin ) : Ext.plugin.Abstract

let element = document.body.querySelector('ExtD3_treemap');
let destroyPlugin = element.destroyPlugin(plugin);

Removes and destroys a plugin.

Note: Not all plugins are designed to be removable. Consult the documentation for the specific plugin in question to be sure.

Available since: 6.2.0

Parameters

plugin :  String/Ext.plugin.Abstract

The plugin or its id to remove.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

disable

let element = document.body.querySelector('ExtD3_treemap');
element.disable();

Disables this Component

doAddListener ( name, fn, scope, options, order, caller, manager )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.doAddListener(name, fn, scope, options, order, caller, manager);

Parameters

name :  Object

fn :  Object

scope :  Object

options :  Object

order :  Object

caller :  Object

manager :  Object

doDestroy

let element = document.body.querySelector('ExtD3_treemap');
element.doDestroy();

Perform the actual destruction sequence. This is the method to override in your subclasses to add steps specific to the destruction of custom Component.

If the Component is currently added to a Container it will first be removed from that Container. All Ext.Element references are also deleted and the Component is de-registered from Ext.ComponentManager.

As a rule of thumb, subclasses should destroy their child Components, Elements, and/or other objects before calling parent method. Any object references will be nulled after this method has finished, to prevent the possibility of memory leaks.

Available since: 6.2.0

doFireDelegatedEvent ( eventName, args )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.doFireDelegatedEvent(eventName, args);

Fires a delegated event. Users should not invoke this method directly. It is called automatically by the framework as needed (see the "delegate" event option of addListener for more details.

Parameters

eventName :  Object

args :  Object

doFireEvent ( eventName, args, bubbles )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.doFireEvent(eventName, args, bubbles);

Continue to fire event.

Parameters

eventName :  String

args :  Array

bubbles :  Boolean

doInheritUi
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.doInheritUi();

doUninheritUi
private pri

let element = document.body.querySelector('ExtD3_treemap');

enable

let element = document.body.querySelector('ExtD3_treemap');
element.enable();

Enables this Component

enableBubble ( eventNames )

let element = document.body.querySelector('ExtD3_treemap');
element.enableBubble(eventNames);

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component#getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

Ext.define('Ext.overrides.form.field.Base', {
    override: 'Ext.form.field.Base',

    //  Add functionality to Field's initComponent to enable
    // the change event to bubble
    initComponent: function () {
        this.callParent();
        this.enableBubble('change');
    }
});

var myForm = Ext.create('Ext.form.Panel', {
    title: 'User Details',
    items: [{
        ...
    }],
    listeners: {
        change: function() {
            // Title goes red if form has been modified.
            myForm.header.setStyle('color', 'red');
        }
    }
});

Parameters

eventNames :  String/String[]

The event name to bubble, or an Array of event names.

findFloatParent ( needsShow )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.findFloatParent(needsShow);

The method finds this floated component's floatParent. That means a DOM positioning container which acts as a root element for sibling floated components, and allows allows floated components to be absolutely positioned, and their encapsulating elements to be reordered to produce a visual stacking effect.

This component's element is appended to its floatParent.

There is a global floatParent element, created on demand when the first top level floated component is shown. This may be an item child of a container configured with cfg-floated: true, or a free floated component which is programatically shown.

Child items of components inside a floated component may also be configured floated. These are give a floatParent which is created on demand wrapping the nearest floated ancestor. This means that when that ancestor's element is brought to the top of the stack (by moving its element to the end of its own floatParent), the descendant elements will automatically remain above.

Parameters

needsShow :  Object

findFocusTarget Ext.Component
private pri

let element = document.body.querySelector('ExtD3_treemap');
let findFocusTarget = element.findFocusTarget();

Finds an alternate Component to focus if this Component is disabled while focused, or focused while disabled, or otherwise unable to focus.

In both cases, focus must not be lost to document.body, but must move to an intuitively connectible Component, either a sibling, or uncle or nephew.

This is both for the convenience of keyboard users, and also for when focus is tracked within a Component tree such as for ComboBoxes and their dropdowns.

For example, a ComboBox with a PagingToolbar in is BoundList. If the "Next Page" button is hit, the LoadMask shows and focuses, the next page is the last page, so the "Next Page" button is disabled. When the LoadMask hides, it attempt to focus the last focused Component which is the disabled "Next Page" button. In this situation, focus should move to a sibling within the PagingToolbar.

Returns

:Ext.Component

A closely related focusable Component to which focus can move.

findNode ( node, [selection] ) : d3.selection
private pri

let element = document.body.querySelector('ExtD3_treemap');
let findNode = element.findNode(node, selection);

Looks up node in the given selection by node's ID and returns node's element, as a D3 selection. Notes:

  • selection should have DOM elements bound (should consist of rendered nodes);
  • the returned selection can be empty, if the node wasn't found; selection.empty() can be used to check this;
  • in most cases using the selectionFromRecord method is preferable, as it is faster; however this method will find the node's element even if the enter selection was not passed to the onNodesAdd method.

Parameters

node :  d3.hierarchy

selection :  d3.selection (optional)

Defaults to all rendered nodes, if omitted.

Returns

:d3.selection

Node's element, as a D3 selection.

findPlugin ( type ) : Ext.plugin.Abstract

let element = document.body.querySelector('ExtD3_treemap');
let findPlugin = element.findPlugin(type);

Retrieves plugin by its type alias. For example:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

 list.findPlugin('pullrefresh').setPullRefreshText('Pull to refresh...');

Note: See also getPlugin.

Available since: 6.2.0

Parameters

type :  String

The Plugin's type as specified by the class's alias configuration.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

fireAction ( eventName, args, fn, [scope], [options], [order] )
deprecated dep

let element = document.body.querySelector('ExtD3_treemap');
element.fireAction(eventName, args, fn, scope, options, order);

Fires the specified event with the passed parameters and executes a function (action). By default, the action function will be executed after any "before" event handlers (as specified using the order option of addListener), but before any other handlers are fired. This gives the "before" handlers an opportunity to cancel the event by returning false, and prevent the action function from being called.

The action can also be configured to run after normal handlers, but before any "after" handlers (as specified using the order event option) by passing 'after' as the order parameter. This configuration gives any event handlers except for "after" handlers the opportunity to cancel the event and prevent the action function from being called.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function

The action function.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

Event options for the action function. Accepts any of the options of addListener

order :  String (optional)

The order to call the action function relative too the event handlers ('before' or 'after'). Note that this option is simply used to sort the action function relative to the event handlers by "priority". An order of 'before' is equivalent to a priority of 99.5, while an order of 'after' is equivalent to a priority of -99.5. See the priority option of addListener for more details.

Defaults to: 'before'

Deprecated since version 5.5
Use fireEventedAction instead.

fireEvent ( eventName, args ) : Boolean

let element = document.body.querySelector('ExtD3_treemap');
let fireEvent = element.fireEvent(eventName, args);

Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object...

Variable number of parameters are passed to handlers.

Returns

:Boolean

returns false if any of the handlers return false otherwise it returns true.

fireEventArgs ( eventName, args ) : Boolean

let element = document.body.querySelector('ExtD3_treemap');
let fireEventArgs = element.fireEventArgs(eventName, args);

Fires the specified event with the passed parameter list.

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object[]

An array of parameters which are passed to handlers.

Returns

:Boolean

returns false if any of the handlers return false otherwise it returns true.

fireEventedAction ( eventName, args, fn, [scope], [fnArgs] ) : Boolean

let element = document.body.querySelector('ExtD3_treemap');
let fireEventedAction = element.fireEventedAction(eventName, args, fn, scope, fnArgs);

Fires the specified event with the passed parameters and executes a function (action). Evented Actions will automatically dispatch a 'before' event passing. This event will be given a special controller that allows for pausing/resuming of the event flow.

By pausing the controller the updater and events will not run until resumed. Pausing, however, will not stop the processing of any other before events.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function/String

The action function.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

fnArgs :  Array/Boolean (optional)

Optional arguments for the action fn. If not given, the normal args will be used to call fn. If false is passed, the args are used but if the first argument is this instance it will be removed from the args passed to the action function.

Returns

:Boolean

focus ( [selectText] ) : Boolean

let element = document.body.querySelector('ExtD3_treemap');
let focus = element.focus(selectText);

If this component is disabled or otherwise not focusable, a close relation will be targeted for focus instead to keep focus localized for keyboard users.

Parameters

selectText :  Boolean/Number[] (optional)

If applicable, true to also select all the text in this component, or an array consisting of start and end (defaults to start) position of selection.

Returns

:Boolean

true if focus target was found and focusing was attempted, false if no focusing attempt was made.

Pass true to return inheritedStateInner instead of the normal inheritedState object. This is only needed internally and should not be passed by user code.

Defaults to: false

Returns

:Object

The inheritedState object containing inherited properties.

getInheritedConfig ( property, [skipThis] ) : Mixed

let element = document.body.querySelector('ExtD3_treemap');
let getInheritedConfig = element.getInheritedConfig(property, skipThis);

This method returns the value of a config property that may be inherited from some ancestor.

In some cases, a config may be explicitly set on a component with the intent of only being presented to its children while that component should act upon the inherited value (see referenceHolder for example). In these cases the skipThis parameter should be specified as true.

Available since: 5.0.0

Parameters

property :  String

The name of the config property to return.

skipThis :  Boolean (optional)

Pass true if the property should be ignored if found on this instance. In other words, true means the property must be inherited and not explicitly set on this instance.

Defaults to: false

    text: 'Test Button'
});

Calling btn.getInitialConfig() would return an object including the config options passed to the create method:

xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'

Calling btn.getInitialConfig('text')returns 'Test Button'.

This may be overridden by Component authors who implement ownership hierarchies which are not based upon ownerCt, such as BoundLists being owned by Fields or Menus being owned by Buttons.

getRenderTarget Ext.dom.Element
private pri

let element = document.body.querySelector('ExtD3_treemap');
let getRenderTarget = element.getRenderTarget();

Returns the element into which the html content and items should be rendered. This defaults to the bodyElement but derived classes can override this method to use a different element.

getStateBuilder ( [cache] ) : Ext.state.Builder
private pri

let element = document.body.querySelector('ExtD3_treemap');
let getStateBuilder = element.getStateBuilder(cache);

Creates a state builder to access or edit this instance's state object. If this instance has a getStatefulOwner, the returned builder will have a parent reference that owner's state builder. This can be an arbitrarily deep chain but does proceed all the way up to the root instance (with no owner) since that is the instance that determines the ultimate state storage key.

Parameters

cache :  Boolean (optional)

Pass true to return a cached builder.

Defaults to: false

Returns

:Ext.state.Builder

getStatefulOwner Ext.state.Stateful/Array
private pri

let element = document.body.querySelector('ExtD3_treemap');
let getStatefulOwner = element.getStatefulOwner();

This method allows a class to specify an owning stateful object. This is used by Ext.plugin.Abstract to save their state as part of their owning <ExtComponent/>.

The return value can be either a Stateful object or an array whose first element is a Stateful object. This object's state will be stored inside the state object of the returned Stateful object. If an array is returned, the elements beyond the first are sub-keys in the state object.

For example, Ext.plugin.Abstract implement this method like so:

 getStatefulOwner: function() {
     return [ this.cmp, 'plugins' ];
 }

The effect of this is to produce a state object like so:

 {
     plugins: {
         pluginId1: {
             //...
         }
     }
 }

In order for a child object's state to be saved and restored, all of its parents must also be stateful (i.e., have a stateId).

Returns

:Ext.state.Stateful/Array

getTabIndex Number

let element = document.body.querySelector('ExtD3_treemap');
let getTabIndex = element.getTabIndex();

Return the actual tabIndex for this Focusable.

Returns

:Number

tabIndex attribute value

getX : Number

Sets the value of x

getXTypes String

let element = document.body.querySelector('ExtD3_treemap');
let getXTypes = element.getXTypes();

Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the <ExtComponent/> header.

Note: If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

Example usage:

var t = new Ext.field.Text();
alert(t.getXTypes());  // alerts 'component/field/textfield'

Returns

:String

The xtype hierarchy string.

getY : Number

Sets the value of y

initDragConstraints ( draggable )
template tpl

let element = document.body.querySelector('ExtD3_treemap');
element.initDragConstraints(draggable);

This method is called when a drag is initializing. This method should adjust the drag constraints to ensure all drag movements are properly restricted. See Ext.drag.Source#constrain.

Available since: 6.5.0

Parameters

draggable :  Ext.drag.Source

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

initElement
protected pro

let element = document.body.querySelector('ExtD3_treemap');
element.initElement();

Initializes the Element for this Widget instance. If this is the first time a Widget of this type has been instantiated the element config will be processed to create an Element. This Element is then cached on the prototype (see afterCachedConfig) so that future instances can obtain their element by simply cloning the Element that was cached by the first instance.

initElementListeners ( elementConfig )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.initElementListeners(elementConfig);

Called for the first instance of this Widget to create an object that contains the listener configs for all of the element references keyed by reference name. The object is cached on the prototype and has the following shape:

_elementListeners: {
    element: {
        click: 'onClick',
        scope: this
    },
    fooReference: {
        tap: {
            fn: someFunction,
            delay: 100
        }
    }
}

The returned object is prototype chained to the _elementListeners object of its superclass, and each key in the object is prototype chained to object with the corresponding key in the superclass _elementListeners. This allows element listeners to be inherited and overridden when subclassing widgets.

This method is invoked with the prototype object as the scope

Parameters

elementConfig :  Object

initFocusableElement ( force )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.initFocusableElement(force);

Sets up the focus listener on this Component's focusEl if it has one.

Form Components which must implicitly participate in tabbing order usually have a naturally focusable element as their focusEl, and it is the DOM event of that receiving focus which drives the Component's onFocus handling, and the DOM event of it being blurred which drives the onBlur handling.

Parameters

force :  Object

initFocusableEvents ( force )
protected pro

let element = document.body.querySelector('ExtD3_treemap');
element.initFocusableEvents(force);

Template method to do any event listener initialization for a Focusable. This generally happens after the focusEl is available.

Parameters

inheritedState :  Object

initKeyMap
protected pro

let element = document.body.querySelector('ExtD3_treemap');
element.initKeyMap();

initUiReference ( referenceName, uiCls, [isInstance] )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.initUiReference(referenceName, uiCls, isInstance);

Initializes a "uiReference". Ui rerefences are reference elements that have classCls and ui info in their CSS class names.

Parameters

referenceName :  String

uiCls :  String

isInstance :  Boolean (optional)

pass false if this is not an instance-level reference

Defaults to: false

:Boolean

true if this component descends from the specified xtype, false otherwise.

labelSizer ( node, element )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.labelSizer(node, element);

Parameters

node :  Object

element :  Object

loadState ( state, stateful ) : Object
private pri

let element = document.body.querySelector('ExtD3_treemap');
let loadState = element.loadState(state, stateful);

This method is called to load state from the provided state builder. This method should return the config properties loaded from state.

This method, like saveState, can be overridden by derived classes:

 loadState: function(state) {
     var ret = this.callParent([ state ]);

     if (ret.foo) {
         // use custom data...

         delete ret.foo;  // remove it since it isn't a config
     }

     return ret;
 }

When overriding this method, it is also likely necessary to override saveState.

Parameters

state :  Ext.state.Builder

stateful :  Object

The stateful properties as an object keyed by config name.

Returns

:Object

lookupController ( [skipThis] ) : Ext.app.ViewController

let element = document.body.querySelector('ExtD3_treemap');
let lookupController = element.lookupController(skipThis);

Gets the controller that controls this view. May be a controller that belongs to a view higher in the hierarchy.

Available since: 5.0.1

Parameters

skipThis :  Boolean (optional)

true to not consider the controller directly attached to this view (if it exists).

Defaults to: false

Returns

:Ext.app.ViewController

The controller. null if no controller is found.

lookupNameHolder ( [skipThis] ) : Ext.Component
private pri

let element = document.body.querySelector('ExtD3_treemap');
let lookupNameHolder = element.lookupNameHolder(skipThis);

Gets the Form or Component that is used as the name holder for this component.

Available since: 6.5.0

Parameters

skipThis :  Boolean (optional)

false to return this as the name holder if this instance has set nameHolder. Unlike getInheritedConfig this method defaults to true because it is possible that a name property set by the owner of a component that is also a nameHolder itself. In this case, the name connects not to this component but to the parent nameHolder.

Defaults to: true

Returns

:Ext.Component

The name holder.

lookupReferenceHolder ( [skipThis] ) : Ext.app.ViewController/Ext.Container
private pri

let element = document.body.querySelector('ExtD3_treemap');
let lookupReferenceHolder = element.lookupReferenceHolder(skipThis);

Gets the Controller or Component that is used as the reference holder for this view.

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

false to return this as the reference holder if this instance has set referenceHolder. Unlike getInheritedConfig this method defaults to true because it is possible that a reference property set by the owner of a component that is also a referenceHolder itself. In this case, the reference connects not to this component but to the parent referenceHolder.

Defaults to: true

Returns

:Ext.app.ViewController/Ext.Container

The reference holder.

lookupSession ( [skipThis] ) : Ext.data.Session

let element = document.body.querySelector('ExtD3_treemap');
let lookupSession = element.lookupSession(skipThis);

Returns the Ext.data.Session for this instance. This property may come from this instance's session or be inherited from this object's parent.

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

Pass true to ignore a session configured on this instance and only consider an inherited session.

Defaults to: false

Returns

:Ext.data.Session

lookupTpl ( name ) : Ext.XTemplate

let element = document.body.querySelector('ExtD3_treemap');
let lookupTpl = element.lookupTpl(name);

Gets a named template instance for this class. See Ext.XTemplate#getTpl.

Available since: 6.2.0

Parameters

name :  String

The name of the property that holds the template.

Returns

:Ext.XTemplate

The template, null if not found.

lookupViewModel ( [skipThis] ) : Ext.app.ViewModel

let element = document.body.querySelector('ExtD3_treemap');
let lookupViewModel = element.lookupViewModel(skipThis);

Returns the Ext.app.ViewModel for this instance. This property may come from this this instance's viewModel or be inherited from this object's parent.

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

Pass true to ignore a viewModel configured on this instance and only consider an inherited view model.

Defaults to: false

Returns

:Ext.app.ViewModel

mon ( item, ename, [fn], [scope], [options] ) : Object

let element = document.body.querySelector('ExtD3_treemap');
let mon = element.mon(item, ename, fn, scope, options);

Shorthand for addManagedListener. The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function/String (optional)

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

options :  Object (optional)

If the ename parameter was an event name, this is the addListener options.

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners = myButton.mon({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

mun ( item, ename, [fn], [scope] )

let element = document.body.querySelector('ExtD3_treemap');
element.mun(item, ename, fn, scope);

Shorthand for removeManagedListener. Removes listeners that were added by the mon method.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item from which to remove a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the ename parameter was an event name, this is the handler function.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

nodeFromRecord ( record ) : d3.hierarchy

let element = document.body.querySelector('ExtD3_treemap');
let nodeFromRecord = element.nodeFromRecord(record);

Returns the associated rendered node. The returned value can be null, if the given record doesn't have a DOM representation.

Parameters

record :  Ext.data.TreeModel

Returns

:d3.hierarchy

d3.hierarchy instance or null, if the node wasn't found.

nodeSizeFn ( selection )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.nodeSizeFn(selection);

Parameters

selection :  Object

on ( eventName, [fn], [scope], [options], [order] ) : Object

let element = document.body.querySelector('ExtD3_treemap');
let on = element.on(eventName, fn, scope, options, order);

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  String/Object

The name of the event to listen for. May also be an object who's property names are event names.

fn :  Function/String (optional)

The method the event invokes or the name of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#fireEvent plus the options parameter described below.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

An object containing handler configuration.

Note: The options object will also be passed as the last argument to every event handler.

This object may contain any of the following properties:

scope :  Object

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean

True to add a handler to handle just the next firing of the event, and then remove itself.

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to <ExtComponent/>. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of <ExtComponent/> which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
      title: 'The title',
      listeners: {
          click: this.handlePanelClick,
          element: 'body'
      }
  });

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional set of arguments to pass to the handler function before the actual fired event arguments. For example, if args is set to ['foo', 42], the event handler function will be called with an arguments list like this:

 handler('foo', 42, <actual event arguments>...);

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

Defaults to: 'current'

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners =  = myButton.on({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

onRender
template tpl

let element = document.body.querySelector('ExtD3_treemap');
element.onRender();

This method is called the first time a component is inserted into the DOM. If this component <ExtContainer/> other components, the onRender method for child components is called after the parent's onRender.

Implementations of this method should avoid modifying the DOM but are free to read from and measure elements as needed. To adjust the DOM, consider implementing afterRender instead.

If this method is overridden, be sure to use callParent to call the base class version.

 onRender: function() {
     this.callParent();

     // custom actions
 }

This method is not generally needed because components always have their own DOM element and these are maintained by config property updaters prior to insertion in the DOM. In general, it is always best to interrogate the component's elements outside the DOM where there is no associated reflow or layout cost. This method is useful for situations where the component's elements must be in the DOM. For example to be measured correctly.

Parameters

component :  Object

alignment :  Object

options :  Object

processElementConfig Object
private pri

let element = document.body.querySelector('ExtD3_treemap');
let processElementConfig = element.processElementConfig();

Recursively processes the element templates for this class and its superclasses, ascending the hierarchy until it reaches a superclass whose element template has already been processed. This method is invoked using the prototype as the scope.

Returns

:Object

publishState ( [property], [value] )
protected pro

let element = document.body.querySelector('ExtD3_treemap');
element.publishState(property, value);

Publish this components state to the ViewModel. If no arguments are given (or if this is the first call), the entire state is published. This state is determined by the publishes property.

This method is called only by component authors.

Available since: 5.0.0

Parameters

property :  String (optional)

The name of the property to update.

value :  Object (optional)

The value of property. Only needed if property is given.

readStateObject Object
private pri

realign ( component, alignment, options )
private pri

let element = document.body.querySelector('ExtD3_treemap');
element.realign(component, alignment, options);

Parameters

component :  Object

alignment :  Object

options :  Object

relayEvents ( origin, events, [prefix] ) : Object

let element = document.body.querySelector('ExtD3_treemap');
let relayEvents = element.relayEvents(origin, events, prefix);

Relays selected events from the specified Observable as if the events were fired by this.

For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:

this.relayEvents(this.getStore(), ['load']);

The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword (unless the event is handled by a controller's control/listen event listener in which case 'this' will be the controller rather than the grid).

Parameters

origin :  Object

The Observable whose events this object is to relay.

events :  String[]/Object

Array of event names to relay or an Object with key/value pairs translating to ActualEventName/NewEventName respectively. For example: this.relayEvents(this, {add:'push', remove:'pop'});

Would now redispatch the add event of this as a push event and the remove event as a pop event.

prefix :  String (optional)

A common prefix to prepend to the event names. For example:

this.relayEvents(this.getStore(), ['load', 'clear'], 'store');

Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

Returns

:Object

A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:

this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');

Can be undone by calling

Ext.destroy(this.storeRelayers);

or this.store.relayers.destroy();

newCls :  String/String[]

The class(es) to add.

prefix :  String (optional)

Optional prefix to prepend before each class.

showBy ( component, [alignment], [options] )

let element = document.body.querySelector('ExtD3_treemap');
element.showBy(component, alignment, options);

Shows this component by another component. If you specify no alignment, it will automatically position this component relative to the reference component depending upon the alignment parameter.

The alignment parameter describes the edge-to-edge alignment of this component with the target. It can be specified thus:

  • Blank: Defaults to positioning where the component will fit trying 'l-r?', 'r-l?', 'b-t?' then 't-b?' in that order.
  • Two anchors: If two values from the table below are passed separated by a dash, the first value is used as the element's anchor point, and the second value is used as the target's anchor point.
  • Two edge/offset descriptors: An edge/offset descriptor is an edge initial (t/r/b/l) followed by a percentage along that side. This describes a point to align with a similar point in the target. So 't0-b0' would be the same as 'tl-bl', 'l0-r50' would place the top left corner of this item halfway down the right edge of the target item. This allows more flexibility and also describes which two edges are considered adjacent when positioning a tip pointer.

Following are all of the supported predefined anchor positions:

 Value  Description
 -----  -----------------------------
 tl     The top left corner
 t      The center of the top edge
 tr     The top right corner
 l      The center of the left edge
 c      The center
 r      The center of the right edge
 bl     The bottom left corner
 b      The center of the bottom edge
 br     The bottom right corner

You can put a '?' at the end of the alignment string to constrain the positioned element to the Ext.Viewport. The element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints.

Example Usage:

// show `panel` by `button` using the default positioning (auto fit)
panel.showBy(button);

// align the top left corner of `panel` with the top right corner of `button`
// (constrained to viewport)
panel.showBy(button, "tl-tr?");

// align the bottom right corner of `panel` with the center left edge of `button`
// (not constrained by viewport)
panel.showBy(button, "br-cl");

// align the center of panel with the bottom left corner of button and
// adjust the x position by -6 pixels (and the y position by 0)
panel.showBy(button, "c-bl", [-6, 0]);

// align the 25% point on the bottom edge of this panel
// with the 75% point on the top edge of button.
panel.showBy(button, 'b25-t75');

Parameters

component :  Ext.Component

The target component to show this component by.

alignment :  String (optional)

The alignment string, eg: 'tl-bl'.

options :  Object/Array (optional)

An object containing options for the Ext.util.Region#alignTo method, if an Array is used, it will be assumed to be the offset.

    statics: {
        totalCreated: 0,
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'

Override members of this class. Overridden methods can be invoked via callParent.

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Direct use of this method should be rare. Use Ext.define instead:

Ext.define('My.CatOverride', {
    override: 'My.Cat',
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
