A tag name or DomHelper spec used to create the Element which will encapsulate this Component. ...

A tag name or DomHelper spec used to create the Element which will encapsulate this Component.

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, this defaults to 'div'. The more complex Sencha classes use a more complex DOM structure specified by their own renderTpls.

This is intended to allow the developer to create application-specific utility Components encapsulated by different DOM elements. Example usage:

{
    xtype: 'component',
    autoEl: {
        tag: 'img',
        src: 'http://www.example.com/example.jpg'
    }
}, {
    xtype: 'component',
    autoEl: {
        tag: 'blockquote',
        html: 'autoEl is cool!'
    }
}, {
    xtype: 'container',
    autoEl: 'ul',
    cls: 'ux-unordered-list',
    items: {
        xtype: 'component',
        autoEl: 'li',
        html: 'First list item'
    }
}

An alias for loader config which also allows to specify just a string which will be used as the url that's automatically loaded:

Ext.create('Ext.Component', {
    autoLoad: 'content.html',
    renderTo: Ext.getBody()
});

The above is the same as:

Ext.create('Ext.Component', {
    loader: {
        url: 'content.html',
        autoLoad: true
    },
    renderTo: Ext.getBody()
});

Don't use it together with loader config.

This cfg has been deprected since 4.1.1

Use loader config instead.

This config is intended mainly for non-floating Components which may or may not be shown. Instead of using renderTo in the configuration, and rendering upon construction, this allows a Component to render itself upon first show. If floating is true, the value of this config is omitted as if it is true.

Specify as true to have this Component render to the document body upon first show.

The base CSS class to apply to this component's element. ...

The base CSS class to apply to this component's element. This will also be prepended to elements within this component like Panel's body will get a class x-panel-body. This means that if you create a subclass of Panel, and you want it to get all the Panels styling for the element and the body, you leave the baseCls x-panel and use componentCls to add specific styling for this component.

Defaults to: 'x-component'

Specifies the border size for this component. ...

Specifies the border size for this component. The border can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10' (top, right, bottom, left).

For components that have no border by default, setting this won't make the border appear by itself. You also need to specify border color and style:

border: 5,
style: {
    borderColor: 'red',
    borderStyle: 'solid'
}

To turn off the border, use border: false.

Ext.AbstractComponent
view source
: Object[]
An array describing the child elements of the Component. ...

An array describing the child elements of the Component. Each member of the array is an object with these properties:

  • name - The property name on the Component for the child element.
  • itemId - The id to combine with the Component's id that is the id of the child element.
  • id - The id of the child element.

If the array member is a string, it is equivalent to { name: m, itemId: m }.

For example, a Component which renders a title and body text:

Ext.create('Ext.Component', {
    renderTo: Ext.getBody(),
    renderTpl: [
        '<h1 id="{id}-title">{title}</h1>',
        '<p>{msg}</p>',
    ],
    renderData: {
        title: "Error",
        msg: "Something went wrong"
    },
    childEls: ["title"],
    listeners: {
        afterrender: function(cmp){
            // After rendering the component will have a title property
            cmp.title.setStyle({color: "red"});
        }
    }
});

A more flexible, but somewhat slower, approach is renderSelectors.

The sizing and positioning of a Component's internal Elements is the responsibility of the Component's layout manager which sizes a Component's internal structure in response to the Component being sized.

Generally, developers will not use this configuration as all provided Components which need their internal elements sizing (Such as input fields) come with their own componentLayout managers.

The default layout manager will be used on instances of the base Ext.Component class which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.

Specify an existing HTML element, or the id of an existing HTML element to use as the content for this component. ...

Specify an existing HTML element, or the id of an existing HTML element to use as the content for this component.

This config option is used to take an existing HTML element and place it in the layout element of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.

Notes:

The specified HTML element is appended to the layout element of the component after any configured HTML has been inserted, and so the document will not contain this element at the time the render event is fired.

The specified HTML element used will not participate in any layout scheme that the Component may use. It is just HTML. Layouts operate on child items.

Add either the x-hidden or the x-hide-display CSS class to prevent a brief flicker of the content before it is rendered to the panel.

Create the Component as a floating and use absolute positioning.

The z-index of floating Components is handled by a ZIndexManager. If you simply render a floating Component into the DOM, it will be managed by the global WindowManager.

If you include a floating Component as a child item of a Container, then upon render, Ext JS will seek an ancestor floating Component to house a new ZIndexManager instance to manage its descendant floaters. If no floating ancestor can be found, the global WindowManager will be used.

When a floating Component which has a ZindexManager managing descendant floaters is destroyed, those descendant floaters will also be destroyed.

This is only necessary when running on outdated, or non standard-compliant browsers such as Microsoft's Internet Explorer prior to version 9 which do not support rounded corners natively.

The extra space taken up by this framing is available from the read only property frameSize.

  • 'visibility' : The Component will be hidden using the visibility: hidden style.
  • 'offsets' : The Component will be hidden by absolutely positioning it out of the visible area of the document. This is useful when a hidden Component must maintain measurable dimensions. Hiding using display results in a Component having zero dimensions.

This content is inserted into the body before any configured contentEl is appended.

Defaults to: ''

Ext.AbstractComponent
view source
: String
The unique id of this component instance. ...

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 ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The 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.

Note: To access the container of a Component see ownerCt.

Defaults to an auto-assigned id.

Available since: 1.1.0

: String
An itemId can be used as an alternative way to get a reference to a component when no object reference is available. ...

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.Container.getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container -- avoiding potential conflicts with Ext.ComponentManager which requires a unique id.

var c = new Ext.panel.Panel({ //
    height: 300,
    renderTo: document.body,
    layout: 'auto',
    items: [
        {
            itemId: 'p1',
            title: 'Panel 1',
            height: 150
        },
        {
            itemId: 'p2',
            title: 'Panel 2',
            height: 150
        }
    ]
})
p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling

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

Note: to access the container of an item see ownerCt.

A config object containing one or more event handlers to be added to this object during initialization. ...

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 Components

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

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

An array of plugins to be added to this component. ...

An array of plugins to be added to this component. Can also be just a single plugin instead of array.

Plugins provide custom functionality for a component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.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.

Plugins can be added to component by either directly referencing the plugin instance:

plugins: [Ext.create('Ext.grid.plugin.CellEditing', {clicksToEdit: 1})],

By using config object with ptype:

plugins: [{ptype: 'cellediting', clicksToEdit: 1}],

Or with just a ptype:

plugins: ['cellediting', 'gridviewdragdrop'],

See Ext.enums.Plugin for list of all ptypes.

An object containing properties specifying DomQuery selectors which identify child elements created by the render process.

After the Component's internal structure is rendered according to the renderTpl, this object is iterated through, and the found Elements are added as properties to the Component using the renderSelector property name.

For example, a Component which renders a title and description into its element:

Ext.create('Ext.Component', {
    renderTo: Ext.getBody(),
    renderTpl: [
        '<h1 class="title">{title}</h1>',
        '<p>{desc}</p>'
    ],
    renderData: {
        title: "Error",
        desc: "Something went wrong"
    },
    renderSelectors: {
        titleEl: 'h1.title',
        descEl: 'p'
    },
    listeners: {
        afterrender: function(cmp){
            // After rendering the component will have a titleEl and descEl properties
            cmp.titleEl.setStyle({color: "red"});
        }
    }
});

For a faster, but less flexible, alternative that achieves the same end result (properties for child elements on the Component after render), see childEls and addChildEls.

Do not use this option if the Component is to be a child item of a Container. It is the responsibility of the Container's layout manager to render and manage its child items.

When using this config, a call to render() is not required.

An XTemplate used to create the internal structure inside this Component's encapsulating Element. ...

An XTemplate used to create the internal structure inside this Component's encapsulating Element.

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, this defaults to null which means that they will be initially rendered with no internal structure; they render their Element empty. The more specialized Ext JS and Sencha Touch classes which use a more complex DOM structure, provide their own template definitions.

This is intended to allow the developer to create application-specific utility Components with customized internal structure.

Upon rendering, any created child elements may be automatically imported into object properties using the renderSelectors and childEls options.

If this property is a number, it is interpreted as follows: 0: Neither width nor height depend on content. ...

If this property is a number, it is interpreted as follows:

  • 0: Neither width nor height depend on content. This is equivalent to false.
  • 1: Width depends on content (shrink wraps), but height does not.
  • 2: Height depends on content (shrink wraps), but width does not. The default.
  • 3: Both width and height depend on content (shrink wrap). This is equivalent to true.

In CSS terms, shrink-wrap width is analogous to an inline-block element as opposed to a block-level element. Some container layouts always shrink-wrap their children, effectively ignoring this property (e.g., Ext.layout.container.HBox, Ext.layout.container.VBox, Ext.layout.component.Dock).

Defaults to: 2

An array of events that, when fired, should trigger this object to save its state. ...

An array of events that, when fired, should trigger this object to save its state. Defaults to none. stateEvents may be any type of event supported by this object, including browser or custom events (e.g., ['click', 'customerchange']).

See stateful for an explanation of saving and restoring object state.

The unique id for this object to use for state management purposes. ...

The unique id for this object to use for state management purposes.

See stateful for an explanation of saving and restoring state.

A flag which causes the object to attempt to restore the state of internal properties from a saved state on startup. ...

A flag which causes the object to attempt to restore the state of internal properties from a saved state on startup. The object must have a stateId for state to be managed.

Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a object.

For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available.

To set the state provider for the current page:

Ext.state.Manager.setProvider(new Ext.state.CookieProvider({ expires: new Date(new Date().getTime()+(10006060247)), //7 days from now }));

A stateful object attempts to save state when one of the events listed in the stateEvents configuration fires.

To save state, a stateful object first serializes its state by calling getState.

The Component base class implements getState to save its width and height within the state only if they were initially configured, and have changed from the configured value.

The Panel class saves its collapsed state in addition to that.

The Grid class saves its column state in addition to its superclass state.

If there is more application state to be save, the developer must provide an implementation which first calls the superclass method to inherit the above behaviour, and then injects new properties into the returned object.

The value yielded by getState is passed to Ext.state.Manager.set which uses the configured Ext.state.Provider to save the object keyed by the stateId.

During construction, a stateful object attempts to restore its state by calling Ext.state.Manager.get passing the stateId

The resulting object is passed to applyState*. The default implementation of applyState simply copies properties into the object, but a developer may override this to support restoration of more complex application state.

You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events.

A value to control how Components are laid out in a Border layout or as docked items. ...

A value to control how Components are laid out in a Border layout or as docked items.

In a Border layout, this can control how the regions (not the center) region lay out if the west or east take full height or if the north or south region take full width. Also look at the Ext.layout.container.Border.regionWeights on the Border layout. An example to show how you can take control of this is:

Ext.create('Ext.container.Viewport', {
    layout      : 'border',
    defaultType : 'panel',
    items       : [
        {
            region : 'north',
            title  : 'North',
            height : 100
        },
        {
            region : 'south',
            title  : 'South',
            height : 100,
            weight : -25
        },
        {
            region : 'west',
            title  : 'West',
            width  : 200,
            weight : 15
        },
        {
            region : 'east',
            title  : 'East',
            width  : 200
        },
        {
            region : 'center',
            title  : 'center'
        }
    ]
});

If docked items, the weight will order how the items are laid out. Here is an example to put a Ext.toolbar.Toolbar above a Ext.panel.Panel's header:

Ext.create('Ext.panel.Panel', {
    renderTo    : document.body,
    width       : 300,
    height      : 300,
    title       : 'Panel',
    html        : 'Panel Body',
    dockedItems : [

This property provides a shorter alternative to creating objects than using a full class name. ...

This property provides a shorter alternative to creating objects than using a full class name. Using xtype is the most common way to define component instances, especially in a container. For example, the items in a form containing text fields could be created explicitly like so:

 items: [
     Ext.create('Ext.form.field.Text', {
         fieldLabel: 'Foo'
     }),
     Ext.create('Ext.form.field.Text', {
         fieldLabel: 'Bar'
     }),
     Ext.create('Ext.form.field.Number', {
         fieldLabel: 'Num'
     })
 ]

But by using xtype, the above becomes:

 items: [
     {
         xtype: 'textfield',
         fieldLabel: 'Foo'
     },
     {
         xtype: 'textfield',
         fieldLabel: 'Bar'
     },
     {
         xtype: 'numberfield',
         fieldLabel: 'Num'
     }
 ]

When the xtype is common to many items, Ext.container.AbstractContainer.defaultType is another way to specify the xtype for all items that don't have an explicit xtype:

 defaultType: 'textfield',
 items: [
     { fieldLabel: 'Foo' },
     { fieldLabel: 'Bar' },
     { fieldLabel: 'Num', xtype: 'numberfield' }
 ]

Each member of the items array is now just a "configuration object". These objects are used to create and configure component instances. A configuration object can be manually used to instantiate a component using Ext.widget:

 var text1 = Ext.create('Ext.form.field.Text', {
     fieldLabel: 'Foo'
 });

 // or alternatively:

 var text1 = Ext.widget({
     xtype: 'textfield',
     fieldLabel: 'Foo'
 });

This conversion of configuration objects into instantiated components is done when a container is created as part of its {Ext.container.AbstractContainer.initComponent} process. As part of the same process, the items array is converted from its raw array form into a Ext.util.MixedCollection instance.

You can define your own xtype on a custom component by specifying the xtype property in Ext.define. For example:

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

Care should be taken when naming an xtype in a custom component because there is a single, shared scope for all xtypes. Third part components should consider using a prefix to avoid collisions.

Ext.define('Foo.form.CoolButton', {
    extend: 'Ext.button.Button',
    xtype: 'ux-coolbutton',
    text: 'Cool!'
});

See Ext.enums.Widget for list of all available xtypes.

This object holds a key for any event that has a listener. ...

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 MVC 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);

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

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.

If the focusEl is not naturally focusable, then the listeners are only added if the FocusManager is enabled.

Ext.AbstractComponent
view source
( element, listeners, scope, options ) : Object
Appends an event handler to this object. ...

Appends an event handler to this object. For example:

myGridPanel.on("mouseover", this.onMouseOver, 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,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    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},
    mouseover: {fn: panel.onMouseOver, scope: panel}
});

Names of methods in a specified scope may also be used. Note that scope MUST be specified to use this option:

myGridPanel.on({
    cellClick: {fn: 'onCellClick', scope: this, single: true},
    mouseover: {fn: 'onMouseOver', scope: panel}
});

Parameters

Returns

  • Object

    Only when the destroyable option is specified.

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

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

Overrides: Ext.util.Positionable.afterSetPosition

( element, [position], [offsets], [animate] ) : Ext.util.Positionablechainable
Aligns the element with another element relative to the specified anchor points. ...

Aligns the element with another element relative to the specified anchor points. If the other element is the document it aligns it to the viewport. The position parameter is optional, and can be specified in any one of the following formats:

  • Blank: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").
  • One anchor (deprecated): The passed anchor position is used as the target element's anchor point. The element being aligned will position its top-left corner (tl) to that point. This method has been deprecated in favor of the newer two anchor syntax below.
  • Two anchors: If two values from the table below are passed separated by a dash, the first value is used as the element's anchor point, and the second value is used as the target's anchor point.

In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints. Following are all of the supported anchor positions:

Value  Description
-----  -----------------------------
tl     The top left corner (default)
t      The center of the top edge
tr     The top right corner
l      The center of the left edge
c      In the center of the element
r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner

Example Usage:

// align el to other-el using the default positioning
// ("tl-bl", non-constrained)
el.alignTo("other-el");

// align the top left corner of el with the top right corner of other-el
// (constrained to viewport)
el.alignTo("other-el", "tr?");

// align the bottom right corner of el with the center left edge of other-el
el.alignTo("other-el", "br-l?");

// align the center of el with the bottom left corner of other-el and
// adjust the x position by -6 pixels (and the y position by 0)
el.alignTo("other-el", "c-bl", [-6, 0]);

Parameters

  • element : Ext.util.Positionable/HTMLElement/String

    The Positionable, HTMLElement, or id of the element to align to.

  • position : String (optional)

    The position to align to

    Defaults to: "tl-bl?"

  • offsets : Number[] (optional)

    Offset the positioning by [x, y]

  • animate : Boolean/Object (optional)

    true for the default animation or a standard Element animation config object

Returns

( animObj ) : Object
Performs custom animation on this object. ...

Performs custom animation on this object.

This method is applicable to both the Component class and the Sprite class. It performs animated transitions of certain properties of this object over a specified timeline.

Animating a Component

When animating a Component, the following properties may be specified in from, to, and keyframe objects:

  • x - The Component's page X position in pixels.

  • y - The Component's page Y position in pixels

  • left - The Component's left value in pixels.

  • top - The Component's top value in pixels.

  • width - The Component's width value in pixels.

  • height - The Component's height value in pixels.

  • dynamic - Specify as true to update the Component's layout (if it is a Container) at every frame of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.

For example, to animate a Window to a new size, ensuring that its internal layout and any shadow is correct:

myWindow = Ext.create('Ext.window.Window', {
    title: 'Test Component animation',
    width: 500,
    height: 300,
    layout: {
        type: 'hbox',
        align: 'stretch'
    },
    items: [{
        title: 'Left: 33%',
        margins: '5 0 5 5',
        flex: 1
    }, {
        title: 'Left: 66%',
        margins: '5 5 5 5',
        flex: 2

});
myWindow.show();
myWindow.header.el.on('click', function() {
    myWindow.animate({
        to: {
            width: (myWindow.getWidth() == 500) ? 700 : 500,
            height: (myWindow.getHeight() == 300) ? 400 : 300
        }
    });
});

For performance reasons, by default, the internal layout is only updated when the Window reaches its final "to" size. If dynamic updating of the Window's child Components is required, then configure the animation with dynamic: true and the two child items will maintain their proportions during the animation.

Parameters

Occurs before componentLayout is run. ...

Occurs before componentLayout is run. In previous releases, this method could return false to prevent its layout but that is not supported in Ext JS 4.1 or higher. This method is simply a notification of the impending layout to give the component a chance to adjust the DOM. Ideally, DOM reads should be avoided at this time to reduce expensive document reflows.

An alternative constraint may be passed.

Parameters

  • constrainTo : String/HTMLElement/Ext.Element/Ext.util.Region (optional)

                          // alerts "Meeeeoooowwww"

This method has been deprected

as of 4.1. Use callParent instead.

Parameters

  • args : Array/Arguments

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

Returns

  • Object

    Returns the result of calling the overridden method

Call the "parent" method of the current method. ...

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 methods.

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

     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',

     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.

Parameters

  • args : Array/Arguments

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

Returns

  • Object

    Returns the result of calling the parent method

This method is used by an override to call the superclass method but bypass any overridden 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', {
     method: function () {
         console.log('Bad');

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

         this.callParent();
     }
 });

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

 Ext.define('App.paches.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".

Parameters

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

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

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

Example:

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

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

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

Parameters

  • eventNames : String/String[]

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

Returns the [X, Y] vector by which this Positionable's element must be translated to make a best attempt to constrain within the passed constraint. Returns false if the element does not need to be moved.

Priority is given to constraining the top and left within the constraint.

The constraint may either be an existing element into which the element is to be constrained, or a Region into which this element is to be constrained.

By default, any extra shadow around the element is not included in the constrain calculations - the edges of the element are used as the element bounds. To constrain the shadow within the constrain region, set the constrainShadow property on this element to true.

Parameters

  • constrainTo : Ext.util.Positionable/HTMLElement/String/Ext.util.Region (optional)

    The Positionable, HTMLElement, element id, or Region into which the element is to be constrained.

  • proposedPosition : Number[] (optional)

    A proposed [X, Y] position to test for validity and to produce a vector for instead of using the element's current position

  • proposedSize : Number[] (optional)

    A proposed [width, height] size to constrain instead of using the element's current size

A component's hierarchyState is used to keep track of aspects of a component's state that affect its descendants hier...

A component's hierarchyState is used to keep track of aspects of a component's state that affect its descendants hierarchically like "collapsed" and "hidden". For example, if this.hierarchyState.hidden == true, it means that either this component, or one of its ancestors is hidden.

Hierarchical state management is implemented by chaining each component's hierarchyState property to its parent container's hierarchyState property via the prototype. The result is such that if a component's hierarchyState does not have it's own property, it inherits the property from the nearest ancestor that does.

To set a hierarchical "hidden" value:

this.getHierarchyState().hidden = true;

It is important to remember when unsetting hierarchyState properties to delete them instead of just setting them to a falsy value. This ensures that the hierarchyState returns to a state of inheriting the value instead of overriding it To unset the hierarchical "hidden" value:

delete this.getHierarchyState().hidden;

IMPORTANT! ALWAYS access hierarchyState using this method, not by accessing this.hierarchyState directly. The hierarchyState property does not exist until the first time getHierarchyState() is called. At that point getHierarchyState() walks up the component tree to establish the hierarchyState prototype chain. Additionally the hierarchyState property should NOT be relied upon even after the initial call to getHierarchyState() because it is possible for the hierarchyState to be invalidated. Invalidation typically happens when a component is moved to a new container. In such a case the hierarchy state remains invalid until the next time getHierarchyState() is called on the component or one of its descendants.

Determines whether this Component is the root of a layout. ...

Determines whether this Component is the root of a layout. This returns true if this component can run its layout without assistance from or impact on its owner. If this component cannot run its layout given these restrictions, false is returned and its owner will be considered as the next candidate for the layout root.

Setting the _isLayoutRoot property to true causes this method to always return true. This may be useful when updating a layout of a Container which shrink wraps content, and you know that it will not change size, and so can safely be the topmost participant in the layout run.

Ext.AbstractComponent

Parameters

  • deep : Boolean (optional)

    Pass true to interrogate the visibility status of all parent Containers to determine whether this Component is truly visible to the user.

    Generally, to determine whether a Component is hidden, the no argument form is needed. For example when creating dynamically laid out UIs in a hidden Container before showing them.

    Defaults to: false

Returns

  • Boolean

    true if this component is visible, false otherwise.

Ext.AbstractComponent

( xtype, [shallow] ) : Boolean
Tests whether or not this Component is of a specific xtype. ...

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.form.field.Text();
var isText = t.isXType('textfield');        // true
var isBoxSubclass = t.isXType('field');       // true, descended from Ext.form.field.Base
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.form.field.Base instance

Available since: 2.3.0

Parameters

  • xtype : String

    The xtype to check for this Component

  • shallow : Boolean (optional)

    true to check whether this Component is directly of the specified xtype, false to check whether this Component is descended from the xtype.

    Defaults to: false

Returns

  • Boolean

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

Returns the next node in the Component tree in tree traversal order.

Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with nextSibling.

Parameters

Returns

  • Ext.Component

    The next node (or the next node which matches the selector). Returns null if there is no matching node.

Ext.AbstractComponent
view source
( [selector] ) : Ext.Component
Returns the next sibling of this Component. ...

Returns the next sibling of this Component.

Optionally selects the next sibling which matches the passed ComponentQuery selector.

May also be referred to as next()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with nextNode

Parameters

Returns

  • Ext.Component

    The next sibling (or the next sibling which matches the selector). Returns null if there is no matching sibling.

( eventName, [fn], [scope], [options] ) : Object
Shorthand for addListener. ...

Shorthand for addListener.

Parameters

  • eventName : String/Object

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

  • fn : Function (optional)

    The method the event invokes, or if scope is specified, 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: Unlike in ExtJS 3.x, 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.

    • 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 Components. The name of a Component property which references an element to add a listener to.

      This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

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

      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 handers 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.

      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
      });
      

Returns

  • Object

    Only when the destroyable option is specified.

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

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

    And when those listeners need to be removed:

    Ext.destroy(this.btnListeners);
    

    or

    this.btnListeners.destroy();

Called by Component#doAutoRender

Register a Container configured floating: true with this Component's ZIndexManager.

Components added in this way will not participate in any layout, but will be rendered upon first show in the way that Windows are.

Parameters

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

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.

Parameters

  • origin : Object

    The Observable whose events this object is to relay.

  • events : String[]

    Array of event names to relay.

  • prefix : String (optional)

    A common prefix to prepend to the event names. For example:

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

    Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

Returns

  • Object

    A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:

    this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
    

    Can be undone by calling

    Ext.destroy(this.storeRelayers);
    

    or this.store.relayers.destroy();

Remove any anchor to this element. ...

Remove any anchor to this element. See anchorTo.

Returns

Removes items in the childEls array based on the return value of a supplied test function. ...

( ui )
Method which removes a specified UI + uiCls from the components element. ...

Method which removes a specified UI + uiCls from the components element. The cls which is added to the element will be: this.baseCls + '-' + ui.

Parameters

  • ui : String

    The UI to add to the element.

Ext.AbstractComponent
view source
( )private
Method which removes a specified UI from the components element. ...

Method which removes a specified UI from the components element.

( [container], [position] )
Renders the Component into the passed HTML element. ...

Renders the Component into the passed HTML element.

If you are using a Container object to house this Component, then do not use the render method.

A Container's child Components are rendered by that Container's layout manager when the Container is first rendered.

If the Container is already rendered when a new child Component is added, you may need to call the Container's doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once.

When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must configure the Container with a layout manager which creates and manages the type of layout you have in mind.

Omitting the Container's layout config means that a basic layout manager is used which does nothing but render child components sequentially into the Container. No sizing or positioning will be performed in this situation.

Parameters

  • container : Ext.Element/HTMLElement/String (optional)

    The element this Component should be rendered into. If it is being created from existing markup, this should be omitted.

  • position : String/Number (optional)

    The element ID or DOM node index within the container before which this component will be inserted (defaults to appending to the end of the container)

Note that if the suspendEvent method is called multiple times for a certain event, this converse method will have to be called the same number of times for it to resume firing.

Parameters

  • eventName : String...

    Multiple event names to resume.

Resumes firing events (see suspendEvents). ...

Resumes firing events (see suspendEvents).

If events were suspended using the queueSuspended parameter, then all events fired during event suspension will be sent to any listeners now.

                          // alerts "Meeeeoooowwww"

As of 4.1, direct use of this method is deprecated. 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).

This method has been deprected since 4.1.0
