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.
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.
Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions. Public classes and members may safely be extended via a subclass.
Protected class members are stable public members intended to be used by the
owning class or its subclasses. Protected members may safely be extended via a subclass.
Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
static label next to the
method name. *See Static below.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).
Let's look at each part of the member row:
lookupComponent in this example)( item ) in this example)Ext.Component in this case). This may be omitted for methods that do not
return anything other than undefined or may display as multiple possible values
separated by a forward slash / signifying that what is returned may depend on the
results of the method call (i.e. a method may return a Component if a get method calls is
successful or false if unsuccessful which would be displayed as
Ext.Component/Boolean).PROTECTED in
this example - see the Flags section below)Ext.container.Container in this example). The source
class will be displayed as a blue link if the member originates from the current class
and gray if it is inherited from an ancestor or mixed-in class.view source in the example)item : Object in the example).undefined a "Returns" section
will note the type of class or object returned and a description (Ext.Component in the
example)Available since 3.4.0 - not pictured in
the example) just after the member descriptionDefaults to: false)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.
classInstance.method1().method2().etc();false is returned from
an event handler- 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
- Indicates a class member of type config
- Indicates a class member of type property
- Indicates a class member of type

- Indicates a class member of type event
- Indicates a class member of type

- Indicates a class member of type
theme mixin
- Indicates that the class, member, or guide is new in the currently viewed version
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.
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.
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.
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 and inheritance. 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.
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:
Ext.button.Button class has an alternate class name of Ext.Button). Alternate class
names are commonly maintained for backward compatibility.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.
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:
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.
The template used to format the Array of error messages passed to setActiveErrors into a single HTML string. if the msgTarget is title, it defaults to a list separated by new lines. Otherwise, it renders each message as an item in an unordered list.
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
Sets the value of alwaysOnTop
alwaysOnTop : Boolean / Number
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
Sets the value of ariaAttributes
ariaAttributes : Object
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.
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.
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.
True to set the field's DOM element autocapitalize attribute to "on", false to set to "off".
Defaults to: null
Sets the value of autoCapitalize
autoCapitalize : Boolean
True to set the field's DOM element autocomplete attribute to "on", false to set to "off".
Defaults to: null
True to set the field DOM element autocorrect attribute to "on", false to set to "off".
Defaults to: null
Whether to adjust the component's body width to make room for error messages.
Defaults to: true
true to auto select the first value in the store or options when they are changed. Only happens when
the value is set to null.
Defaults to: true
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
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#defaultBindProperty for the binding.
Defaults to: null
The horizontal alignment of this field's component within the body of the field
Defaults to: 'start'
Returns the value of bodyAlign
'start' / 'center' / 'end' / 'stretch'
Sets the value of bodyAlign
bodyAlign : 'start' / 'center' / 'end' / 'stretch'
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).
Ext.Viewport.add({
centered: true,
width: 100,
height: 100,
style: 'border: 1px solid blue;'
// ...
});
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
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
Defaults to: [ 'action' ]
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
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
The element into which floated or positioned items constrain their position.
Defaults to the parent container for positioned components, and to the viewport for floated components.
Defaults to: null
Sets the value of constrainTo
constrainTo : Ext.dom.Element / Ext.util.Region
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
Returns the value of contentEl
Ext.dom.Element / HTMLElement / String
Sets the value of contentEl
contentEl : Ext.dom.Element / HTMLElement / String
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
Returns the Ext.app.ViewController instance associated with this component via the controller config or setController method.
Returns this component's ViewController or null if one was not configured
Sets the value of controller
controller : String / Object / Ext.app.ViewController
The initial set of data to apply to the tpl to update the content area of the Component.
Defaults to: null
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
Sets the value of defaultListenerScope
defaultListenerScope : Boolean
The default configuration for the picker component when you are on a phone.
Defaults to: null
Sets the value of defaultPhonePickerConfig
defaultPhonePickerConfig : Object
The default configuration for the picker component when you are on a tablet.
Defaults to: null
Sets the value of defaultTabletPickerConfig
defaultTabletPickerConfig : Object
The underlying data value name (or numeric Array index) to bind to this Select control. This resolved value is the visibly rendered value of the available selection options.
Defaults to: 'text'
Sets the value of displayField
displayField : String / Number
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
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.
Sets the value of enterAnimation
enterAnimation : String / Mixed
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' }
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'.
Sets the value of exitAnimation
exitAnimation : String / Mixed
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 with camel-cased names 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
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 relative: true`.
Defaults to: false
Available since: 6.2.0
CSS class that will be added to focused component's focusClsEl, and removed when component blurs.
Defaults to: 'x-focused'
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
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
Sets the value of hideAnimation
hideAnimation : String / Mixed
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
Optional HTML content to render inside this Component, or a reference to an existing element on the page.
Defaults to: null
Returns the value of html
String / Ext.dom.Element / HTMLElement
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.
Retrieves the id of this component. Will autogenerate an id if one has not already been set.
id
Defaults to: 15
The type attribute for input fields -- e.g. text, password, date, url, email, etc.
Defaults to: 'text'
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 itemIds or ids. Since itemIds 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.
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
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
listeners. It defaults to the "controller", but using 'this'
means that an instance method will be used.
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
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'
When value is 'placeholder', the label text will be rendered as placeholder
text inside the empty input and will animated to "top" alignment when the input
is focused or contains text.
The position to render the label
relative to the field input.
Defaults to: 'left'
Returns the value of labelAlign
'top' / 'left' / 'bottom' / 'right' / 'placeholder'
Sets the value of labelAlign
labelAlign : 'top' / 'left' / 'bottom' / 'right' / 'placeholder'
Text alignment of this field's label
Defaults to: 'left'
Returns the value of labelTextAlign
'top' / 'right' / 'bottom' / 'left'
Sets the value of labelTextAlign
labelTextAlign : 'top' / 'right' / 'bottom' / 'left'
true to allow the label to wrap. If set to false, the label will be truncated with
an ellipsis.
Defaults to: false
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
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 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'); }
}
}
});
An alias for addListener. In versions prior to 5.1, listeners had a generated setter which could be called to add listeners. In 5.1 the listeners config is not processed using the config system and has no generated setter, so this method is provided for backward compatibility. The preferred way of adding listeners is to use the on method.
listeners : Object
The listeners
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
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
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
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
Defaults to: null
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
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
[msgTarget="qtip"] The location where the error message text should display. Must be one of the following values:
Defaults to: 'qtip'
The field's HTML name attribute.
Note: this property must be set if this field is to be automatically included with. form submit().
Defaults to: 'picker'
Set to true for this component's name property to be tracked by its containing
nameHolder.
Defaults to: false
An array of select options.
[
{text: 'First Option', value: 'first'},
{text: 'Second Option', value: 'second'},
{text: 'Third Option', value: 'third'}
]
Note: Option object member names should correspond with defined valueField and displayField values. This config will be ignored if a store instance is provided.
Defaults to: null
The padding to use on this Component. Can be specified as a number (in which case all edges get the same padding) or a CSS string like '5 10 10 10'
Defaults to: null
The value for the HTML5 pattern attribute. You can use this to change which keyboard layout will be used.
Ext.define('Ux.field.Pattern', {
extend : 'Ext.field.Text',
xtype : 'patternfield',
config : {
component : {
pattern : '[0-9]*'
}
}
});
Even though it extends Ext.field.Text, it will display the number keyboard.
Defaults to: null
The alignment of text in the picker created by this Select
Defaults to: 'center'
Sets the value of pickerSlotAlign
pickerSlotAlign : String
A string value displayed in the input when the control is empty.
Note This config is deprecated, use lowercase placeholder config.
Defaults to: null
A string value displayed in the input when the control is empty.
Defaults to: null
An object or array of objects that will provide custom functionality for this
component. If a string is provided or a string is one of the elements of the
array, that string is treated as the type alias. For example, "listpaging"
is the type alias for Ext.plugin.ListPaging. The full alias includes the
"plugin." prefix (i.e., 'plugin.listpaging').
Plugins should derive from Ext.plugin.Abstract but this is not required. The
only requirement for a valid plugin is that it contain an init() method that
accepts a reference to the owning component.
When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.
A plugin by alias:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: 'listpaging'
});
Multiple plugins by alias:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: ['listpaging', 'pullrefresh']
});
Single plugin by class name with config options:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: {
type: 'listpaging',
autoPaging: true
}
});
Multiple plugins by type and class name with config options:
var list = Ext.create({
xtype: 'list',
itemTpl: '<div class="item">{title}</div>',
store: 'Items',
plugins: [{
xclass: 'Ext.plugin.PullRefresh',
pullRefreshText: 'Pull to refresh...'
}, {
type: 'listpaging',
autoPaging: true
}]
});
Defaults to: null
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 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 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: null
Available since: 5.0.0
Returns the value of publishes
String / String[] / Object
Sets the value of publishes
publishes : String / String[] / Object
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
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
Only valid when a component is 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
Optional element to render this Component to. Not required if this component is an item of a Container of a Container.
Defaults to: null
true to make this field required.
Note: this only causes a visual indication.
Doesn't prevent user from submitting the form.
Defaults to: false
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
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.horizontal to enable horizontal scrolling onlyvertical to enable vertical scrolling onlyAlso 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
Returns the value of scrollable
Boolean / String / Object
Sets the value of scrollable
scrollable : Boolean / String / Object
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
Returns the value of session
Boolean / Object / Ext.data.Session
Sets the value of session
session : Boolean / Object / Ext.data.Session
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
Only valid when a component is floated
Configure as true for the component to use an <iframe> as an underlay to ensure certain non-standard
browser plugins are occluded by this component.
Defaults to: false
Available since: 6.2.0
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
Sets the value of showAnimation
showAnimation : String / Mixed
The store to provide selection options data. Either a Store instance, configuration object or store ID.
Defaults to: null
Returns the value of store
Ext.data.Store / Object / String
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
The tabIndex for this field. Note this only applies to fields that are rendered,
not those which are built via applyTo.
Defaults to: null
Return the actual tabIndex for this Focusable.
tabIndex attribute value
Set the tabIndex property for this Focusable. If the focusEl is available, set tabIndex attribute on it, too.
newTabIndex : Number
new tabIndex to set
[textAlign='left']. The text alignment of this field.
Defaults to: null
Returns the value of textAlign
'left' / 'center' / 'right'
Sets the value of textAlign
textAlign : 'left' / 'center' / 'right'
True to automatically call toFront when a floated Component is shown.
Defaults to: true
The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or Ext.tip.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
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
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:
panXpanYpinchZoomdoubleTapZoomAll 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
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
Returns the value of tpl
String / String[] / Ext.Template / Ext.XTemplate[]
Sets the value of tpl
tpl : String / String[] / Ext.Template / Ext.XTemplate[]
The Ext.(X)Template method to use when updating the content area of the Component. Valid modes are:
Defaults to: 'overwrite'
Defaults to: null
Defaults to: { expand: { type: 'expand' } }
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
Returns the value of twoWayBindable
String / String[] / Object
Sets the value of twoWayBindable
twoWayBindable : String / String[] / Object
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
true if you want this component to always use a Ext.picker.Picker.
false if you want it to use a popup overlay Ext.List.
auto if you want to show a Ext.picker.Picker only on phones.
Defaults to: 'auto'
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
Defaults to: 'Is in the wrong format'
Sets the value of validationMessage
validationMessage : Object
Defaults to: null
A value to initialize this field with.
Defaults to: null
The underlying data value name (or numeric Array index) to bind to this Select control.
Defaults to: 'value'
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
Returns the value of viewModel
String / Object / Ext.app.ViewModel
Sets the value of viewModel
viewModel : String / Object / Ext.app.ViewModel
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
Only valid when a component is 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
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 by specifying the
alias config option with a prefix of widget. For example:
Ext.define('PressMeButton', {
extend: 'Ext.button.Button',
alias: 'widget.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.
Only valid when a component is 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
The value true causes config values to be stored on instances using a
property name prefixed with an underscore ("_") character. A value of false
stores config values as properties using their exact name (no prefix).
Defaults to: true
Available since: 5.0.0
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
Matches options property names within a listeners specification object - property names which are never used as event names.
Defaults to: { scope: 1, delay: 1, buffer: 1, onFrame: 1, single: 1, args: 1, destroyable: 1, priority: 1, order: 1 }
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
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
Instance specific ARIA attributes to render into Component's ariaEl. This object is only used during rendering, and is discarded afterwards.
ARIA role for this Component, defaults to no role. With no role, no other ARIA attributes are set.
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
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: null
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
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
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
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
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'
This property is set to true after the destroy method is called.
Defaults to: false
Defaults to: { top: true, right: true, bottom: true, left: true }
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:
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).
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.
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 cfg!ui 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' }
Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.
Defaults to: 0
The CSS class to add to this component when it is floated at the viewport level.
Defaults to: "x-floated"
The CSS class to add to this component's floatWrap when it's created.
Defaults to: "x-float-wrap"
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
The element that will have the focusCls applied when component's focusEl is focused.
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'
true if this component's focusEl is focused.
See also containsFocus.
Defaults to: false
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);
}
Template method to do any Focusable related initialization that does not involve event listeners creation.
Defaults to: Ext.emptyFn
This property is set to true during the call to initConfig.
Defaults to: false
Available since: 5.0.0
Set to true on all Ext.field.Field subclasses. This is used by Ext.form.Panel#getValues to determine which
components inside a form are fields.
Defaults to: true
This property is set to true if this instance is the first of its class.
Defaults to: false
Available since: 5.0.0
This value is true and is used to identify plain objects from instances of
a defined class.
Defaults to: true
true in this class to identify an object as an instantiated Observable, or subclass thereof.
Defaults to: true
The label Element associated with this Field.
Map for msg target lookup, if target is not in this map it is assumed to be an element id
Defaults to: { qtip: 1, title: 1, under: 1, side: 1, none: 1 }
The CSS class to add to this component should not have a border.
Defaults to: Ext.baseCSSPrefix + 'noborder-trbl'
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'
}
});
var cat = new My.Cat(); // alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
Defaults to: Base
The CSS class to add to this component when it has a shadow.
Defaults to: Ext.baseCSSPrefix + 'shadow'
The CSS class to add to this component's shim element if enabled.
Defaults to: "x-shim"
The value that the Field had at the time it was last focused. This is the value that is passed to the Ext.field.Text#change event which is fired if the value has been changed when the Field is blurred.
This will be undefined until the Field has been visited. Compare originalValue.
Defaults to: false
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: []
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)
Defaults to: { element: '' }
Regular expression used for validating reference values.
Defaults to: /^[a-z_][a-z0-9_]*$/i
Adds declarative listeners as nested arrays of listener objects.
listeners : Array
true if any listeners were added
Creates a particular plugin type if defined in the plugins configuration.
Available since: 6.2.0
type : String
The type of the plugin.
The plugin that was created.
Ensures that the given property (if it is a Config System config) has a proper "updater" method on this instance to sync changes to the config.
Available since: 5.0.0
property : String
The name of the config property.
Adds a CSS class (or classes) to this Component's rendered element.
cls : String / String[]
The CSS class(es) to add.
prefix : String (optional)
Optional prefix to add to each class.
Defaults to: ""
suffix : String (optional)
Optional suffix to add to each class.
Defaults to: ""
Adds a listeners with the "delegate" event option. Users should not invoke this method directly. Use the "delegate" event option of addListener instead.
eventName : Object
fn : Object
scope : Object
options : Object
order : Object
caller : Object
manager : Object
This method applies a versioned, deprecation declaration to this class. This
is typically called by the deprecated config.
deprecations : Object
Adds an element reference to this Widget instance.
name : String
The name of the reference
domNode : HTMLElement
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.
name : String
The name of the reference
domNode : HTMLElement
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}
});
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 Ext.Component. 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 Ext.Component 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 arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these 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 -100Defaults to: 'current'
order : String (optional)
A shortcut for the order event option. Provided for backward compatibility.
Please use the priority event option instead.
Combining Options
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener.
myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});
Attaching multiple handlers in 1 call
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.
grid.on({
itemclick: 'onItemClick',
itemcontextmenu: grid.onItemContextmenu,
destroy: {
fn: function () {
// function called within the 'altCmp' scope instead of grid
},
scope: altCmp // unique scope for the destroy handler
},
scope: grid // default scope - provided for example clarity
});
Delegate
This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:
var panel = Ext.create({
xtype: 'panel',
renderTo: document.body,
title: 'Delegate Handler Example',
frame: true,
height: 220,
width: 220,
html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});
// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
click: function (e) {
console.log(e.getTarget().innerHTML);
},
element: 'body',
delegate: 'h1.myTitle'
});
Defaults to: 'current'
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();
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.SomeGlobalSharedMenu, '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.
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.
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();

Call the original method that was previously overridden with Ext.Base#override
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.callOverridden();
alert("Meeeeoooowwww");
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
args : Array / Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
Deprecated since version 4.1.0
Use #callParent instead.
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 callSuper. This is often done to patch a method to fix a bug.
args : Array / Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
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 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".

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');
}
}
});
eventNames : String / String[]
The event name to bubble, or an Array of event names.
Search from this component up until we find a component with a controller and return the controller.
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 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.
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.
A closely related focusable Component to which focus can move.
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...');

Available since: 6.2.0
type : String
The Plugin's type as specified by the class's
alias configuration.
plugin instance or null if not found.
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.
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.
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.

eventName : String
The name of the event to fire.
args : Object[]
An array of parameters which are passed to handlers.
returns false if any of the handlers return false otherwise it returns true.
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.
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.
Try to focus this component.
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.
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.
true if focus target was found and focusing was attempted,
false if no focusing attempt was made.
Gets the active error message for this component, if any. This does not trigger validation on its own, it merely returns any message that the component may already hold.

For floated components only.
Finds the owning floated component (if any) responsible for the base z-index stack position of this compoonent, and, if that component is relative, for the coordinate system in which this component is positioned.
If this is a top level floated component, this method will return null
The owning floated component or null if this
component is top level floated.
This method returns, or creates on demand the floatWrap element which wraps the passed floated component. It enables that floated component to act as a host for descendant floated components.
The passed component's floatWrap element.
Returns the stack of floated components in which this Component resides. This Component and all siblings at this level are returned.
selector : String / Function
A ComponentQuery selector, or
a selection function which returns true to select a component.
Returns the main focus holder element associated with this Focusable, i.e. the element that will be focused when Focusable's focus method is called. For the most Focusables this will be the focusEl.
This method returns an object containing the inherited properties for this instance.
Available since: 5.0.0
inner : Boolean (optional)
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
The inheritedState object containing inherited properties.
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
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

xtype: 'mybutton',
scale: 'large',
enableToggle: true
});
var btn = Ext.create({
xtype: 'mybutton',
renderTo: Ext.getBody(),
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'.
name : String (optional)
Name of the config option to return.

}
});
list.getPlugin('foo').setPullRefreshText('Pull to refresh...');
Note: See also findPlugin.
Available since: 6.2.0
id : String
The id of the plugin.
plugin instance or null if not found.
Used by Ext.ComponentQuery, and the up method to find the owning Component in the linkage hierarchy.
By default this returns the Container which contains this Component.
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.
Returns the element that the "rootCls" (x-root) should be applied to.
Should always return the component's main element.
Overridden by Ext.viewport.Default to return the page body element
Returns the height and width of the Component.
width : Number
height : Number
Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component 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'
The xtype hierarchy string.
me : Object
width : Object
height : Object
oldWidth : Object
oldHeight : Object
Tells whether the field currently has an active error message. This does not trigger validation on its own, it merely looks for any message that the component may already hold.
Checks to see if this object has any listeners for a specified event, or whether the event bubbles. The answer indicates whether the event needs firing or not.
eventName : String
The name of the event to check for
true if the event is being listened for or bubbles, else false
Returns true if this component has a parent.
true if this component has a parent.
Hides this Component optionally using an animation.
animation : Object / Boolean (optional)
You can specify an animation here or a bool to use the hideAnimation config.
This method triggers the lazy configs and must be called when it is time to fully boot up. The configs that must be initialized are: bind, publishes, session, twoWayBindable and viewModel.
Available since: 5.0.0
Initialize configuration for this class. a typical example:
Ext.define('My.awesome.Class', {
// The default config
config: {
name: 'Awesome',
isAwesome: true
},
constructor: function(config) {
this.initConfig(config);
}
});
var awesome = new My.awesome.Class({
name: 'Super Awesome'
});
alert(awesome.getName()); // 'Super Awesome'
instanceConfig : Object
this
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
elementConfig : Object
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.
force : Object
Template method to do any event listener initialization for a Focusable. This generally happens after the focusEl is available.
force : Object
This method is called to initialize the inheritedState objects for this instance.
This amounts to typically copying certain properties from the instance to the given
object.
Available since: 5.0.0
inheritedState : Object
The state object for this instance.
inheritedStateInner : Object (optional)
This object is only provided for containers.
This method should be called when the instance is ready to start listening for keyboard events. This is called automatically for Ext.Component and derived classes. In Classic Toolkit, this is done after the component is rendered.
This method inserts this floated component's DOM into its owning floatParent.
This method marks the current inherited state as invalid. The next time a call is made to getInherited the objects will be recreated and initialized.
Available since: 5.0.0
Tests whether this Widget matches a Ext.ComponentQuery selector string.
selector : String
The selector string to test against.
true if this Widget matches the selector.
Determines whether this Component is an ancestor of the passed Component.
This will return true if the passed Component is anywhere within the subtree
beneath this Component.
possibleDescendant : Ext.Component
The Component to test for presence within this Component's subtree.
Determines if the passed property name is bound to ViewModel data.
Available since: 7.0.0
name : String (optional)

true if the passed property receives data from a ViewModel.
Determines whether this component is the descendant of a passed component.
ancestor : Ext.Component
A Component which may contain this Component.
true if the component is the descendant of the passed component, otherwise false.
Returns true if this Component is currently disabled.
true if currently disabled.
Determine if this Focusable can receive focus at this time.
Note that Containers can be non-focusable themselves while delegating focus treatment to a child Component; see Ext.Container for more information.
deep : Boolean (optional)
Optionally determine if the container itself is focusable, or if container's focus is delegated to a child component and that child is focusable.
Defaults to: false
True if component is focusable, false if not.
Returns true if this Component is currently hidden.
deep : Boolean / Ext.Widget (optional)
true to check if this component
is hidden because a parent container is hidden. Alternatively, a reference to the
top-most parent at which to stop climbing.
Defaults to: false
true if currently hidden.
Checks if all events, or a specific event, is suspended.
event : String (optional)
The name of the specific event to check
true if events are suspended
Checks if a particular binding is synchronizing the value.
name : String
The name of the property being bound to.
true if the binding is syncing.
Returns true if this Component is currently visible.
deep : Boolean (optional)
true to check if this component
is visible and all parents are also visible.
Defaults to: false
true if currently visible.
Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended
from the xtype (default) or whether it is directly of the xtype specified (shallow = true).
**If using your own subclasses, be aware that a Component must register its own xtype
to participate in determination of inherited xtypes.__
For a list of all available xtypes, see the Ext.Component header.
Example usage:
var t = new Ext.field.Text();
var isText = t.isXType('textfield'); // true
var isBoxSubclass = t.isXType('field'); // true, descended from Ext.field.Field
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.field.Field instance
xtype : String
The xtype to check for this Component.
shallow : Boolean (optional)
false to check whether this Component is descended from the xtype (this is
the default), or true to check whether this Component is directly of the specified xtype.
true if this component descends from the specified xtype, false otherwise.
Adds a "destroyable" object to an internal list of objects that will be destroyed when this instance is destroyed (via destroy).
name : String
value : Object
The value passed.
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
skipThis : Boolean (optional)
true to not consider the controller directly attached
to this view (if it exists).
Defaults to: false
The controller. null if no controller is found.
Gets the Form or Component that is used as the name holder for this component.
Available since: 7.0.0
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
The name holder.
Gets the Controller or Component that is used as the reference holder for this view.
Available since: 5.0.0
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
The reference holder.
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
skipThis : Boolean (optional)
Pass true to ignore a session configured on
this instance and only consider an inherited session.
Defaults to: false
Gets a named template instance for this class. See Ext.XTemplate#getTpl.
Available since: 6.2.0
name : String
The name of the property that holds the template.
The template, null if not found.
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
skipThis : Boolean (optional)
Pass true to ignore a viewModel configured on
this instance and only consider an inherited view model.
Defaults to: false
Returns an update method for the given Config that will call publishState
to ensure two-way bindings (via bind) as well as any publishes are updated.
This method is cached on the cfg instance for re-use.
Available since: 5.0.0
cfg : Ext.Config
The updater function.
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.SomeGlobalSharedMenu, '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.
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.
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();
Shorthand for removeManagedListener. Removes listeners that were added by the mon method.
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.
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}
});
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 Ext.Component. 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 Ext.Component 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 arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these 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 -100Defaults to: 'current'
order : String (optional)
A shortcut for the order event option. Provided for backward compatibility.
Please use the priority event option instead.
Combining Options
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener.
myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});
Attaching multiple handlers in 1 call
The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.
grid.on({
itemclick: 'onItemClick',
itemcontextmenu: grid.onItemContextmenu,
destroy: {
fn: function () {
// function called within the 'altCmp' scope instead of grid
},
scope: altCmp // unique scope for the destroy handler
},
scope: grid // default scope - provided for example clarity
});
Delegate
This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:
var panel = Ext.create({
xtype: 'panel',
renderTo: document.body,
title: 'Delegate Handler Example',
frame: true,
height: 220,
width: 220,
html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});
// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
click: function (e) {
console.log(e.getTarget().innerHTML);
},
element: 'body',
delegate: 'h1.myTitle'
});
Defaults to: 'current'
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();

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.
Called when the internal stores data has changed.
store : Object
Returns true if the passed element is within the container tree of this component.
For example if a menu's submenu contains an Ext.form.field.Date, that top level menu owns the elements of the date picker. Using this method, you can tell if an event took place within a certain component tree.
element : Object
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.
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
property : String (optional)
The name of the property to update.
value : Object (optional)
The value of property. Only needed if property is given.
component : Object
alignment : Object
options : Object
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).
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'.
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();
Removes the given CSS class(es) from this Component's rendered element.
cls : String / String[]
The class(es) to remove.
prefix : String (optional)
Optional prefix to prepend before each class.
Defaults to: ""

eventName : String
The type of event the handler was associated with.
fn : Function
The handler to remove. This must be a reference to the function passed into the addListener call.
scope : Object (optional)
The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed.
Convenience Syntax
You can use the addListener
destroyable: true config option in place of calling un(). For example:
var listeners = cmp.on({
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide,
destroyable: true
});
// Remove listeners
listeners.destroy();
// or
cmp.un(
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide
);
Exception - DOM event handlers using the element config option
You must go directly through the element to detach an event handler attached using the addListener element option.
panel.on({
element: 'body',
click: 'onBodyCLick'
});
panel.body.un({
click: 'onBodyCLick'
});

Ext.create('Ext.menu.Menu', {
width: 100,
height: 100,
margin: '0 0 10 0',

this
Shows this component by another component. If you specify no alignment, it will automatically position this component relative to the reference component.
For example, say we are aligning a Panel next to a Button, the alignment string would look like this:
[panel-vertical (t/b/c)][panel-horizontal (l/r/c)]-[button-vertical (t/b/c)][button-horizontal (l/r/c)]
where t = top, b = bottom, c = center, l = left, r = right.
tl-tr means top-left corner of the Panel to the top-right corner of the Buttontc-bc means top-center of the Panel to the bottom-center of the ButtonYou can put a '?' at the end of the alignment string to constrain the positioned element to the Ext.Viewport
// 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?");

Shows the picker for the select field, whether that is a Ext.picker.Picker or a simple list.
focusPicker : Object
Get the reference to the class from which this object was instantiated. Note that unlike Ext.Base#self,
this.statics() is scope-independent and it always returns the class from which it was called, regardless of what
this points to during run-time
Ext.define('My.Cat', {
statics: {
totalCreated: 0,
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},
constructor: function() {
var statics = this.statics();
alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to
// equivalent to: My.Cat.speciesName
alert(this.self.speciesName); // dependent on 'this'
statics.totalCreated++;
},
clone: function() {
var cloned = new this.self(); // dependent on 'this'
cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName
return cloned;
}
});
Ext.define('My.SnowLeopard', {
extend: 'My.Cat',
statics: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
},
constructor: function() {
this.callParent();
}
});
var cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
alert(clone.groupName); // alerts 'Cat'
alert(My.Cat.totalCreated); // alerts 3
Suspends firing of the named event(s).

var listeners = cmp.on({
scope: cmp,
afterrender: cmp.onAfterrender,
beforehide: cmp.onBeforeHide,
destroyable: true
});
// Remove listeners
listeners.destroy();
// or
cmp.un(

mixinClass : Object
Override members of this class. Overridden methods can be invoked via Ext.Base#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).
