Ext.util.AbstractMixedCollectionExt.util.MixedCollectionExt.draw.CompositeSpriteMixins
A composite Sprite handles a group of sprites with common methods to a sprite
-such as hide, show, setAttributes. These methods are applied to the set of sprites
-added to the group.
CompositeSprite extends Ext.util.MixedCollection so you can use the same methods
-in MixedCollection to iterate through sprites, add and remove elements, etc.
In order to create a CompositeSprite, one has to provide a handle to the surface where it is -rendered:
- -var group = Ext.create('Ext.draw.CompositeSprite', {
- surface: drawComponent.surface
-});
-Then just by using MixedCollection methods it's possible to add Ext.draw.Sprites:
group.add(sprite1);
-group.add(sprite2);
-group.add(sprite3);
-And then apply common Sprite methods to them:
- -group.setAttributes({
- fill: '#f00'
-}, true);
-(optional)
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 ExtJs Components
- - -While some ExtJs 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
-click 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'); }
- }
- }
-});
-The default sort direction to use if one is not specified (defaults to "ASC")

Specify true if the addAll -function should add function references to the collection. Defaults to -false.
-A function that can accept an item of the type(s) stored in this MixedCollection -and return the key value for that item. This is used when available to look up the key on items that -were passed without an explicit key parameter to a MixedCollection method. Passing this parameter is -equivalent to providing an implementation for the getKey method.

-Either an object with event names as properties with a value of true

this reference) in which the handler function is executed.
-If omitted, defaults to the object which fired the event.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'
- }
-});
-When added in this way, the options available are the options applicable to Ext.core.Element.addListener
- - -
-Combining Options
-Using the options argument, it is possible to combine different types of listeners:
-
-A delayed, one-time listener.
-
myPanel.on('hide', this.handleClick, this, {
-single: true,
-delay: 100
-});
-Attaching multiple handlers in 1 call
-The method also allows for a single argument to be passed which is a config object containing properties
-which specify multiple events. For example:
-
myGridPanel.on({
- cellClick: this.onCellClick,
- mouseover: this.onMouseOver,
- mouseout: this.onMouseOut,
- scope: this // Important. Ensure "this" is correct during handler execution
-});

Perform custom animation on this object.

This method is applicable to both the the Component class and the Element class. -It performs animated transitions of certain properties of this object over a specified timeline.
-The sole parameter is an object which specifies start property values, end property values, and properties which
-describe the timeline. Of the properties listed below, only to is mandatory.
Properties include

Units must be supplied.height height value. Units must be supplied.scrollLeft scrollLeft value.scrollTop scrollLeft value.opacity opacity value. This must be a value between 0 and 1.Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state -will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to -directly animate certain properties of Components.
-from, to, and keyframe objects:x y left left value in pixels.top top value in pixels.width width value in pixels.width width value in pixels.dynamic 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.
An object containing properties which describe the animation's start and end states, and the timeline of the animation.

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.override(Ext.form.field.Base, {
-// Add functionality to Field's initComponent to enable the change event to bubble
-initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
- this.enableBubble('change');
-}),
-
-// We know that we want Field's events to bubble directly to the FormPanel.
-getBubbleTarget : function() {
- if (!this.formPanel) {
- this.formPanel = this.findParentByType('form');
- }
- return this.formPanel;
-}
-});
-
-var myForm = new Ext.formPanel({
-title: 'User Details',
-items: [{
- ...
-}],
-listeners: {
- change: function() {
- // Title goes red if form has been modified.
- myForm.header.setStyle('color', 'red');
- }
-}
-});
-The event name to bubble, or an Array of event names.
-Filters the objects in this collection by a set of Filters, or by a single -property/value pair with optional parameters for substring matching and case sensitivity. See -Filter for an example of using Filter objects (preferred). Alternatively, -MixedCollection can be easily filtered by property like this:
- - -//create a simple store with a few people defined
-var people = new Ext.util.MixedCollection();
-people.addAll([
- {id: 1, age: 25, name: 'Ed'},
- {id: 2, age: 24, name: 'Tommy'},
- {id: 3, age: 24, name: 'Arne'},
- {id: 4, age: 26, name: 'Aaron'}
-]);
-

-MixedCollection has a generic way to fetch keys if you implement getKey. The default implementation
-simply returns item.id but you can provide your own implementation
-to return a different value as in the following examples:
// normal way
-var mc = new Ext.util.MixedCollection();
-mc.add(someEl.dom.id, someEl);

-Replaces an item in the collection. Fires the replace event when complete.
-The key associated with the item to replace, or the replacement item.

-The Element
-Iterates through all sprites calling

-Sorts the data in the Store by one or more of its properties. Example usage:
- - -//sort by a single field

-Internally, Store converts the passed arguments into an array of Ext.util.Sorter instances, and delegates the actual -sorting to its internal Ext.util.MixedCollection.
- - -When passing a single string argument to sort, Store maintains a ASC/DESC toggler per field, so this code:
- - -store.sort('myField');
-store.sort('myField');
- Is equivalent to this code, because Store handles the toggling automatically:
- - -store.sort('myField', 'ASC');
-store.sort('myField', 'DESC');
