The Draw Component is a surface in which sprites can be rendered. The Draw Component manages and holds an Ext.draw.Surface instance where Sprites can be appended.

One way to create a draw component is:

var drawComponent = Ext.create('Ext.draw.Component', {
    viewBox: false,
    items: [{
        type: 'circle',
        fill: '#79BB3F',
        radius: 100,
        x: 100,
        y: 100
    }]
});

Ext.create('Ext.Window', {
    width: 215,
    height: 235,
    layout: 'fit',
    items: [drawComponent]
}).show();

In this case we created a draw component and added a sprite to it. The type of the sprite is circle so if you run this code you'll see a yellow-ish circle in a Window. When setting viewBox to false we are responsible for setting the object's position and dimensions accordingly.

You can also add sprites by using the surface's add method:

drawComponent.surface.add({
    type: 'circle',
    fill: '#79BB3F',
    radius: 100,
    x: 100,
    y: 100
});

Larger example

var drawComponent = Ext.create('Ext.draw.Component', {
    width: 800,
    height: 600,
    renderTo: document.body
}), surface = drawComponent.surface;

surface.add([{
    type: 'circle',
    radius: 10,
    fill: '#f00',
    x: 10,
    y: 10,
    group: 'circles'
}, {
    type: 'circle',
    radius: 10,
    fill: '#0f0',
    x: 50,
    y: 50,
    group: 'circles'
}, {
    type: 'circle',
    radius: 10,
    fill: '#00f',
    x: 100,
    y: 100,
    group: 'circles'
}, {
    type: 'rect',
    width: 20,
    height: 20,
    fill: '#f00',
    x: 10,
    y: 10,
    group: 'rectangles'
}, {
    type: 'rect',
    width: 20,
    height: 20,
    fill: '#0f0',
    x: 50,
    y: 50,
    group: 'rectangles'
}, {
    type: 'rect',
    width: 20,
    height: 20,
    fill: '#00f',
    x: 100,
    y: 100,
    group: 'rectangles'
}]);

// Get references to my groups
circles = surface.getGroup('circles');
rectangles = surface.getGroup('rectangles');

// Animate the circles down
circles.animate({
    duration: 1000,
    to: {
        translate: {
            y: 200
        }
    }
});

// Animate the rectangles across
rectangles.animate({
    duration: 1000,
    to: {
        translate: {
            x: 200
        }
    }
});

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()
});

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.

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.

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"});

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.

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.

Specify as true to float the Component outside of the document flow using CSS absolute positioning.

Components such as Windows and Menus are floating by default.

Floating Components that are programatically rendered will register themselves with the global ZIndexManager

Floating Components as child items of a Container

A floating Component may be used as a child item of a Container. This just allows the floating Component to seek a ZIndexManager by examining the ownerCt chain.

When configured as floating, Components acquire, at render time, a ZIndexManager which manages a stack of related floating Components. The ZIndexManager brings a single floating Component to the top of its stack when the Component's toFront method is called.

The ZIndexManager is found by traversing up the ownerCt chain to find an ancestor which itself is floating. This is so that descendant floating Components of floating Containers (Such as a ComboBox dropdown within a Window) can have its zIndex managed relative to any siblings, but always above that floating ancestor Container.

If no floating ancestor is found, a floating Component registers itself with the default ZIndexManager.

Floating components do not participate in the Container's layout. Because of this, they are not rendered until you explicitly show them.

After rendering, the ownerCt reference is deleted, and the floatParent property is set to the found floating ancestor Container. If no floating ancestor Container was found the floatParent property will not be set.

Defaults to: false

: Object[]
(optional) Define a set of gradients that can be used as fill property in sprites. ...

(optional) Define a set of gradients that can be used as fill property in sprites. The gradients array is an array of objects with the following properties:

  • id - string - The unique name of the gradient.
  • angle - number, optional - The angle of the gradient in degrees.
  • stops - object - An object with numbers as keys (from 0 to 100) and style objects as values

Example

gradients: [{
    id: 'gradientId',
    angle: 45,
    stops: {
        0: {
            color: '#555'
        },
        100: {
            color: '#ddd'
        }
    }
}, {
    id: 'gradientId2',
    angle: 0,
    stops: {
        0: {
            color: '#590'
        },
        20: {

        },
        100: {
            color: '#ddd'
        }
    }
}]

Then the sprites can use gradientId and gradientId2 by setting the fill attributes to those ids, for example:

sprite.setAttributes({
    fill: 'url(#gradientId)'
}, true);

An HTML fragment, or a DomHelper specification to use as the layout element content.

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

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.

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'

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:

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"});
        }
    }
});

Specify the id of the element, a DOM element or an existing Element that this component will be rendered into.

Notes:

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).

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.

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:

Only present for floating Components which were inserted as child items of Containers, and which have a floating Container in their containment ancestry.

For floating Components which are child items of a Container, the zIndexParent will be a floating ancestor Container which is responsible for the base z-index value of all its floating descendants. It provides a ZIndexManager which provides z-indexing services for all its descendant floating Components.

Floating Components that are programatically rendered will not have a zIndexParent property.

For example, the dropdown BoundList of a ComboBox which is in a Window will have the Window as its zIndexParent, and will always show above that Window, wherever the Window is placed in the z-index stack.

          Either an object with event names as properties with a value of true. For example:

          this.addEvents({
              storeloaded: true,
              storecleared: true
          });
          

          Or any number of event names as separate parameters. For example:

          this.addEvents('storeloaded', 'storecleared');
          
        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.

        Fires

          ( 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'); }
            });

                            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

                                  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.

                                          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.

                                                      By default, this Positionable is constrained to be within the container it was added to, or the element it was rendered to.

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

                                                      An alternative constraint may be passed.

                                                      Parameters

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

                                                        The Element or Region into which this Component is to be constrained. Defaults to the element into which this Positionable was rendered, or this Component's {@link Ext.Component.constrainTo.

                                                      • proposedPosition : Number[] (optional)

                                                        A proposed [X, Y] position to test for validity and to coerce into constraints instead of using this Positionable's current position.

                                                      • local : Boolean (optional)

                                                        The proposedPosition is local (relative to floatParent if a floating Component)

                                                      • proposedSize : Number[] (optional)

                                                        A proposed [width, height] size to use when calculating constraints instead of using this Positionable's current size.

                                                      Returns

                                                      • Number[]

                                                        If the element needs to be translated, the new [X, Y] position within constraints if possible, giving priority to keeping the top and left edge in the constrain region. Otherwise, false.

                                                        • Object

                                                          Returns the result of calling the overridden method

                                                             extend: 'My.Base',

                                                                 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.

                                                          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 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".

                                                              string or config object containing a ptype property.

                                                              Constructs a plugin according to the passed config object/ptype string.

                                                              Ensures that the constructed plugin always has a cmp reference back to this component. The setting up of this is done in PluginManager. The PluginManager ensures that a reference to this component is passed to the constructor. It also ensures that the plugin's setCmp method (if any) is called.

                                                            Returns an array of fully constructed plugin instances. ...

                                                            Returns an array of fully constructed plugin instances. This converts any configs into their appropriate instances.

                                                            It does not mutate the plugins array. It creates a new array.

This information is memoized based upon the CSS class name of this Component's element. Because child Components are rendered as textual HTML as part of the topmost Container, a dummy div is inserted into the document to receive the document element's CSS class name, and therefore style attributes.

                                                                                                            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.

It is intended to be implemented by each subclass of Ext.Component to provide any needed constructor logic. The initComponent method of the class being created is called first, with each initComponent method up the hierarchy to Ext.Component being called thereafter. This makes it easy to implement and, if needed, override the constructor logic of the Component at any step in the hierarchy.

                                                                                                                                  The initComponent method must contain a call to callParent in order to ensure that the parent class' initComponent method is also called.

                                                                                                                                  All config options passed to the constructor are applied to this before initComponent is called, so you can simply access them with this.someOption.

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.

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.

For normal components this equates to the value of isParentRtl(). Floaters are a bit different because a floater's element can be a childNode of something other than its parent component's element. For floaters we have to read the dom to see if the component's element's parentNode has a css direction value of "rtl".

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.

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.

                                                                                                                                                                                      Available since: 2.3.0

                                                                                                                                                                                                    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.

The x/y overflow values can be any valid CSS overflow (e.g., 'auto' or 'scroll'). By default, the value is 'hidden'. Passing null for one of the values will erase the inline style. Passing undefined will preserve the current value.
