<ext-d3_partition/> Ext.d3.hierarchy.partition.Partition premium

alignSelf : String

<ext-d3_partition alignSelf="value" />

let element = document.body.querySelector('ext-d3_partition');
element.alignSelf = 'value';
let alignSelf = element.alignSelf;

Specifies the self alignment of this widget in a box layout

Defaults to:

null

alwaysOnTop : Boolean / Number

<ext-d3_partition alwaysOnTop="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition ariaAttributes="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition ariaDescribedBy="value" />

let element = document.body.querySelector('ext-d3_partition');
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.

ariaLabel : String

immutable imm

<ext-d3_partition ariaLabel="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition ariaLabelledBy="value" />

let element = document.body.querySelector('ext-d3_partition');
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.

ariaRole : String

readonly ro

<ext-d3_partition ariaRole="value" />

let element = document.body.querySelector('ext-d3_partition');
let ariaRole = element.ariaRole;

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

axisLock : Boolean

<ext-d3_partition axisLock="true" />

let element = document.body.querySelector('ext-d3_partition');
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

bind : Object / String

<ext-d3_partition bind="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition border="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition bottom="value" />

let element = document.body.querySelector('ext-d3_partition');
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

centered : Boolean

<ext-d3_partition centered="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition classCls="value" />

let element = document.body.querySelector('ext-d3_partition');
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'

clipScene : Boolean

<ext-d3_partition clipScene="true" />

let element = document.body.querySelector('ext-d3_partition');
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[]

<ext-d3_partition cls="value" />

let element = document.body.querySelector('ext-d3_partition');
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 <ext-container/>).

Defaults to:

null

colorAxis : Ext.d3.axis.Color

<ext-d3_partition colorAxis="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition componentCls="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition constrainAlign="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition containsFocus="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition contentEl="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition controller="value" />

let element = document.body.querySelector('ext-d3_partition');
element.controller = 'value';
let controller = element.controller;

    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

<ext-d3_partition data="{ }" />

let element = document.body.querySelector('ext-d3_partition');
element.data = { };
let data = element.data;

Note: Data will be appended to any existing data.

Defaults to:

null

defaultBindProperty : String

readonly ro

<ext-d3_partition defaultBindProperty="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition defaultCls="value" />

let element = document.body.querySelector('ext-d3_partition');
element.defaultCls = 'value';

    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',

    selected: Ext.baseCSSPrefix + 'd3-selected',
    expanded: Ext.baseCSSPrefix + 'd3-expanded'
}

defaultListenerScope : Boolean

<ext-d3_partition defaultListenerScope="true" />

let element = document.body.querySelector('ext-d3_partition');
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

destroyed : Boolean

readonly ro

<ext-d3_partition destroyed="true" />

let element = document.body.querySelector('ext-d3_partition');
element.destroyed = true;
let destroyed = element.destroyed;

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

Defaults to:

false

disabled : Boolean

<ext-d3_partition disabled="true" />

let element = document.body.querySelector('ext-d3_partition');
element.disabled = true;
let disabled = element.disabled;

Whether or not this component is disabled

Defaults to:

null

displayed : Boolean

<ext-d3_partition displayed="true" />

let element = document.body.querySelector('ext-d3_partition');
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

docked : String

<ext-d3_partition docked="value" />

let element = document.body.querySelector('ext-d3_partition');
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>
    <head>
        <title>MY application title</title>
        ...

Defaults to:

null

draggable : Boolean / Object / Ext.drag.Source

<ext-d3_partition draggable="true" />

let element = document.body.querySelector('ext-d3_partition');
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

expandEventName : String / String[]

<ext-d3_partition expandEventName="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition factoryConfig="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition flex="value" />

let element = document.body.querySelector('ext-d3_partition');
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

floated : Boolean

<ext-d3_partition floated="true" />

let element = document.body.querySelector('ext-d3_partition');
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

floatingCls : String

readonly ro

<ext-d3_partition floatingCls="value" />

let element = document.body.querySelector('ext-d3_partition');
element.floatingCls = 'value';
let floatingCls = element.floatingCls;

The CSS class to add to this component when it is floated at the viewport level.

Defaults to:

Ext.baseCSSPrefix + 'floating'

focusCls : String

immutable imm

<ext-d3_partition focusCls="value" />

let element = document.body.querySelector('ext-d3_partition');
element.focusCls = 'value';
let focusCls = element.focusCls;

CSS class that will be added to focused component's focusClsEl, and removed when component blurs.

Defaults to:

'x-focused'

focusClsEl : Ext.dom.Element

readonly ro

<ext-d3_partition focusClsEl="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition focusEl="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition focusable="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition fullscreen="true" />

let element = document.body.querySelector('ext-d3_partition');
element.fullscreen = true;
let fullscreen = element.fullscreen;

Force the component to take up 100% width and height available, by adding it to Ext.Viewport.

hasFocus : Boolean

readonly ro

<ext-d3_partition hasFocus="true" />

let element = document.body.querySelector('ext-d3_partition');
let hasFocus = element.hasFocus;

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

Defaults to:

false

hasListeners : Object

readonly ro

<ext-d3_partition hasListeners="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition height="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition hidden="true" />

let element = document.body.querySelector('ext-d3_partition');
element.hidden = true;
let hidden = element.hidden;

Whether or not this Component is hidden (its CSS display property is set to none).

Defaults to true for floated Components.

Defaults to:

null

hideAnimation : String / Mixed

<ext-d3_partition hideAnimation="value" />

let element = document.body.querySelector('ext-d3_partition');
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'

<ext-d3_partition hideMode="value" />

let element = document.body.querySelector('ext-d3_partition');
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:

• 'clip' : Hide using clip.
• 'display' : Hide using display.
• 'offsets' : Hide using positioning offsets.
• 'opacity' : Hide using opacity.
• 'visibility' : Hide using visibility.

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

<ext-d3_partition hideOnMaskTap="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition hierarchyCls="value" />

let element = document.body.querySelector('ext-d3_partition');
element.hierarchyCls = 'value';
let hierarchyCls = element.hierarchyCls;

The class name added to all hieararchy components (subclasses). See also componentCls.

Defaults to:

'hierarchy'

html : String / Ext.dom.Element / HTMLElement

<ext-d3_partition html="value" />

let element = document.body.querySelector('ext-d3_partition');
element.html = 'value';
let html = element.html;

Optional HTML content to render inside this Component, or a reference to an existing element on the page.

Defaults to:

null

id : String

immutable imm

<ext-d3_partition id="value" />

let element = document.body.querySelector('ext-d3_partition');
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 <ext-container/> 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

<ext-d3_partition inheritUi="true" />

let element = document.body.querySelector('ext-d3_partition');
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

interactions

<ext-d3_partition interactions="value" />

let element = document.body.querySelector('ext-d3_partition');
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:

[]

isObservable : Boolean

readonly ro

<ext-d3_partition isObservable="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition itemId="value" />

let element = document.body.querySelector('ext-d3_partition');
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 id's. 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

<ext-d3_partition keyMap="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition keyMapEnabled="true" />

let element = document.body.querySelector('ext-d3_partition');
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 <ext-component/> at the proper time, this is not something application code normally handles.

Defaults to:

null

lastKeyMapEvent : Ext.event.Event

readonly ro

<ext-d3_partition lastKeyMapEvent="value" />

let element = document.body.querySelector('ext-d3_partition');
element.lastKeyMapEvent = 'value';
let lastKeyMapEvent = element.lastKeyMapEvent;

The last key event processed is cached on the component for use in subsequent event handlers.

Available since: 6.6.0

layoutTransition

readonly ro

<ext-d3_partition layoutTransition="value" />

let element = document.body.querySelector('ext-d3_partition');
element.layoutTransition = 'value';
let layoutTransition = element.layoutTransition;

The current layout transition. Only active for its duration from the time of the renderScene call.

Defaults to:

null

left : Number / String

<ext-d3_partition left="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition linkKey="function() { }" />

let element = document.body.querySelector('ext-d3_partition');
element.linkKey(link, index);

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

Defaults to:

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

Parameters

Returns

listeners : Object

<ext-d3_partition listeners="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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 <ext-component/>

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 DataView's 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

<ext-d3_partition margin="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition maxHeight="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition maxWidth="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition minHeight="value" />

let element = document.body.querySelector('ext-d3_partition');
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

minWidth : Number / String

<ext-d3_partition minWidth="value" />

let element = document.body.querySelector('ext-d3_partition');
element.minWidth = 'value';
let minWidth = element.minWidth;

The minimum 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.

Defaults to:

null

modal : Boolean

<ext-d3_partition modal="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition modelValidation="true" />

let element = document.body.querySelector('ext-d3_partition');
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:

null

Available since: 6.5.0

let element = document.body.querySelector('ext-d3_partition');
element.name = 'value';
let name = element.name;

Name for the widget to be used with Ext.Container#lookupName et al.

Defaults to:

null

nameable : Boolean

<ext-d3_partition nameable="true" />

let element = document.body.querySelector('ext-d3_partition');
element.nameable = true;
let nameable = element.nameable;

Set to true for this component's name property to be tracked by its containing nameHolder.

Defaults to:

false

noParentValue : Boolean

<ext-d3_partition noParentValue="true" />

let element = document.body.querySelector('ext-d3_partition');
element.noParentValue = true;
let noParentValue = element.noParentValue;

If true the nodeValue function will not be called for parent nodes, instead they'll get a value of zero. The nodeChildren function is used to determine if a node is a parent.

Defaults to:

false

nodeChildren : Function

<ext-d3_partition nodeChildren="function() { }" />

let element = document.body.querySelector('ext-d3_partition');
element.nodeChildren(record);

Children accessor function. Defaults to returning node's child nodes, if the node is expanded or null otherwise (meaning children of collapsed nodes are not rendered).

Defaults to:

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

Parameters

Returns

nodeClass : Function

<ext-d3_partition nodeClass="function() { }" />

let element = document.body.querySelector('ext-d3_partition');
element.nodeClass(selection);

A function that updates class attributes of a given selection. By default adds the following classes to node elements:

• 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

nodeKey : Function

<ext-d3_partition nodeKey="function() { }" />

let element = document.body.querySelector('ext-d3_partition');
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

Returns

nodeText : Function / String / String[]

<ext-d3_partition nodeText="value" />

let element = document.body.querySelector('ext-d3_partition');
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']

Defaults to:

[
    'name',
    'text'
]

Parameters

Returns

nodeValue : Function / String / Number

<ext-d3_partition nodeValue="value" />

let element = document.body.querySelector('ext-d3_partition');
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

Returns

padding : Object / String / Number

<ext-d3_partition padding="value" />

let element = document.body.querySelector('ext-d3_partition');
element.padding = 'value';
let padding = element.padding;

The padding of the scene. See Ext.util.Format#parseBox for syntax details, if using a string for this config.

Defaults to:

0

Properties

right : Number

bottom : Number

left : Number

panZoom : Ext.d3.interaction.PanZoom

readonly ro

<ext-d3_partition panZoom="value" />

let element = document.body.querySelector('ext-d3_partition');
element.panZoom = 'value';
let panZoom = element.panZoom;

If the panzoom interaction has been added, a reference to it is saved on the component instance for quick access.

Defaults to:

null

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

<ext-d3_partition plugins="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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

publishes : String / String[] / Object

<ext-d3_partition publishes="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition record="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition reference="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition relative="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition rendered="true" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition right="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition ripple="true" />

let element = document.body.querySelector('ext-d3_partition');
element.ripple = true;
let ripple = element.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.

rootVisible : Boolean

<ext-d3_partition rootVisible="true" />

let element = document.body.querySelector('ext-d3_partition');
element.rootVisible = true;
let rootVisible = element.rootVisible;

Defaults to:

true

scrollable : Boolean / String / Object

<ext-d3_partition scrollable="true" />

let element = document.body.querySelector('ext-d3_partition');
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[]

<ext-d3_partition selectEventName="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition selection="value" />

let element = document.body.querySelector('ext-d3_partition');
element.selection = 'value';
let selection = element.selection;

Defaults to:

null

session : Boolean / Object / Ext.data.Session

<ext-d3_partition session="true" />

let element = document.body.querySelector('ext-d3_partition');
element.session = true;
let session = element.session;

If provided this creates a new Session instance for this component. If this is a Container, this will then be inherited by all child components.

To create a new session you can specify true:

 Ext.create({
     xtype: 'viewport',
     session: true,

     items: [{
         ...
     }]
 });

Alternatively, a config object can be provided:

 Ext.create({
     xtype: 'viewport',
     session: {
         ...
     },

     items: [{
         ...
     }]
 });

Defaults to:

null

shadow : Boolean

<ext-d3_partition shadow="true" />

let element = document.body.querySelector('ext-d3_partition');
element.shadow = true;
let shadow = element.shadow;

Configure as true for the component to have a drop shadow. 'false' will suppress any default shadow. By default the theme will determine the presence of a shadow.

Defaults to:

null

Available since: 6.2.0

shareableName : Boolean

immutable imm

<ext-d3_partition shareableName="true" />

let element = document.body.querySelector('ext-d3_partition');
element.shareableName = true;
let shareableName = element.shareableName;

Defaults to:

false

Available since: 6.2.0

showAnimation : String / Mixed

<ext-d3_partition showAnimation="value" />

let element = document.body.querySelector('ext-d3_partition');
element.showAnimation = 'value';
let showAnimation = element.showAnimation;

Animation effect to apply when the Component is being shown. Typically you want to use an inbound animation type such as 'fadeIn' or 'slideIn'. For more animations, check the Ext.fx.Animation#type config.

Defaults to:

null

size : Object

<ext-d3_partition size="{ }" />

let element = document.body.querySelector('ext-d3_partition');
element.size = { };
let size = element.size;

Whether or not the component got its first size. Can be used in the sceneresize event handler to do user-defined setup on first resize, for example:

listeners: {
    sceneresize: function(component, scene, rect) {
        if (!component.size) {
            // set things up
        } else {
            // handle resize
        }
    }
}

stateful : Boolean / Object / String[]

<ext-d3_partition stateful="true" />

let element = document.body.querySelector('ext-d3_partition');
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

store : store

<ext-d3_partition store="value" />

let element = document.body.querySelector('ext-d3_partition');
element.store = 'value';
let store = element.store;

The store with data to render.

Defaults to:

null

style : String / Object

<ext-d3_partition style="value" />

let element = document.body.querySelector('ext-d3_partition');
element.style = 'value';
let style = element.style;

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

tabIndex : Number

<ext-d3_partition tabIndex="10" />

let element = document.body.querySelector('ext-d3_partition');
element.tabIndex = 10;
let tabIndex = element.tabIndex;

DOM tabIndex attribute for this component's focusEl.

Defaults to:

null

toFrontOnShow : Boolean

<ext-d3_partition toFrontOnShow="true" />

let element = document.body.querySelector('ext-d3_partition');
element.toFrontOnShow = true;
let toFrontOnShow = element.toFrontOnShow;

True to automatically call toFront when a cfg-floated Component is shown.

Defaults to:

true

tooltip : String / Object

<ext-d3_partition tooltip="value" />

let element = document.body.querySelector('ext-d3_partition');
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 <ext-tooltip/> 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

<ext-d3_partition top="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition touchAction="{ }" />

let element = document.body.querySelector('ext-d3_partition');
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[]

<ext-d3_partition tpl="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition tplWriteMode="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition transitions="value" />

let element = document.body.querySelector('ext-d3_partition');
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
    }
}

twoWayBindable : String / String[] / Object

<ext-d3_partition twoWayBindable="value" />

let element = document.body.querySelector('ext-d3_partition');
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[]

<ext-d3_partition ui="value" />

let element = document.body.querySelector('ext-d3_partition');
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

userCls : String / String[]

<ext-d3_partition userCls="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition userSelectable="true" />

let element = document.body.querySelector('ext-d3_partition');
element.userSelectable = true;
let userSelectable = element.userSelectable;

Set to true to allow users to select text within this component.

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

A value of true implies auto, while false implies none.

May also be an object keyed by child element name.

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

viewModel : String / Object / Ext.app.ViewModel

<ext-d3_partition viewModel="value" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition weight="10" />

let element = document.body.querySelector('ext-d3_partition');
element.weight = 10;
let weight = element.weight;

This value controls this item's order in a weighted <ext-container/> (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

<ext-d3_partition width="value" />

let element = document.body.querySelector('ext-d3_partition');
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

x : Number

<ext-d3_partition x="10" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition xtype="value" />

let element = document.body.querySelector('ext-d3_partition');
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 <ext-component/> 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

<ext-d3_partition y="10" />

let element = document.body.querySelector('ext-d3_partition');
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

<ext-d3_partition zIndex="10" />

let element = document.body.querySelector('ext-d3_partition');
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.

Defaults to:

null

addAfterListener

let element = document.body.querySelector('ext-d3_partition');
element.addAfterListener();

Alias for onAfter.

addBeforeListener

let element = document.body.querySelector('ext-d3_partition');
element.addBeforeListener();

Alias for onBefore.

addCls ( cls, [prefix], [suffix] )

let element = document.body.querySelector('ext-d3_partition');
element.addCls(cls, prefix, suffix);

Adds a CSS class (or classes) to this Component's rendered element.

Parameters

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

chainable ch

let element = document.body.querySelector('ext-d3_partition');
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

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

 panel.body.un(...)

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

false

'current'

Returns

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

Ext.destroy(this.btnListeners);

this.btnListeners.destroy();

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

let element = document.body.querySelector('ext-d3_partition');
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

Returns

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

Ext.destroy(this.btnListeners);

this.btnListeners.destroy();

addPlugin ( plugin )

let element = document.body.querySelector('ext-d3_partition');
element.addPlugin(plugin);

Adds a plugin. For example:

 list.addPlugin('pullrefresh');

Or:

 list.addPlugin({
     type: 'pullrefresh',
     pullRefreshText: 'Pull to refresh...'
 });

Available since: 6.2.0

Parameters

afterRender

template tpl

let element = document.body.querySelector('ext-d3_partition');
element.afterRender();

This method is called after the component is initially added to the DOM. If this component <ext-container/> 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.

alignContent ( options, [transition] )

let element = document.body.querySelector('ext-d3_partition');
element.alignContent(options, transition);

Aligns rendered content in the scene.

Parameters

bubble ( fn, [scope], [args] )

let element = document.body.querySelector('ext-d3_partition');
element.bubble(fn, scope, args);

Bubbles up the getRefOwner hierarchy, calling the specified function with each component. The scope (this reference) of the function call will be the scope provided or the current component. The arguments to the function will be the args provided or the current component. If the function returns false at any point, the bubble is stopped.

Parameters

center Ext.Component

chainable ch

let element = document.body.querySelector('ext-d3_partition');
let center = element.center();

Center this cfg-floated or positioned Component in its parent.

Returns

clearListeners

let element = document.body.querySelector('ext-d3_partition');
element.clearListeners();

Removes all listeners for this object including the managed listeners

clearManagedListeners

let element = document.body.querySelector('ext-d3_partition');
element.clearManagedListeners();

Removes all managed listeners for this object.

constructor ( config )

let element = document.body.querySelector('ext-d3_partition');
element.constructor(config);

Creates new Component.

Parameters

createTransition ( name, [selection] ) : d3.transition

let element = document.body.querySelector('ext-d3_partition');
let createTransition = element.createTransition(name, selection);

Creates a d3.transition instance from a named object in the transitions config.

Parameters

Returns

destroy

let element = document.body.querySelector('ext-d3_partition');
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('ext-d3_partition');
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

destroyPlugin ( plugin ) : Ext.plugin.Abstract

let element = document.body.querySelector('ext-d3_partition');
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

Returns

disable

let element = document.body.querySelector('ext-d3_partition');
element.disable();

Disables this Component

doDestroy

let element = document.body.querySelector('ext-d3_partition');
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

enable

let element = document.body.querySelector('ext-d3_partition');
element.enable();

Enables this Component

enableBubble ( eventNames )

let element = document.body.querySelector('ext-d3_partition');
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

findPlugin ( type ) : Ext.plugin.Abstract

let element = document.body.querySelector('ext-d3_partition');
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...');
