Hierarchy

Ext.data.AbstractStore
Ext.data.TreeStore

Mixins

The TreeStore is a store implementation that is backed by by an Ext.data.Tree. +It provides convenience methods for loading nodes, as well as the ability to use +the hierarchical tree structure combined with a store. This class is generally used +in conjunction with Ext.tree.Panel. This class also relays many events from +the Tree for convenience.

+ +

Using Models

+ +

If no Model is specified, an implicit model will be created that implements Ext.data.NodeInterface. +The standard Tree fields will also be copied onto the Model for maintaining their state.

+ +

Reading Nested Data

+ +

For the tree to read nested data, the Ext.data.Reader must be configured with a root property, +so the reader can find nested data for each node. If a root is not specified, it will default to +'children'.

This may be used in place of specifying a model configuration. The fields should be a +set of Ext.data.Field configuration objects. The store will automatically create a Ext.data.Model +with these fields. In general this configuration option should be avoided, it exists for the purposes of +backwards compatibility. For anything more complicated, such as specifying a particular id property or +assocations, a Ext.data.Model should be defined and specified for the model config.

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'); }

Sets the updating behavior based on batch synchronization. 'operation' (the default) will update the Store's +internal representation of the data after each operation of the batch has completed, 'complete' will wait until +the entire batch has been completed before updating the Store's data.

+

Adds the specified events to the list of events which this Observable may fire.

+

Parameters

  • o : Object/String

    Either an object with event names as properties with a value of true +or the first event name string if multiple event names are being passed as separate parameters.

    +
  • : String

    [additional] Optional additional event names if multiple event names are being passed as separate parameters. +Usage:

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

Returns

  • void    +
 
addListener( +String eventName, Function handler, [Object scope], [Object options]) + : void

Appends an event handler to this object.

+

Appends an event handler to this object.

+

Parameters

  • eventName : String

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

    +
  • handler : Function

    The method the event invokes.

    +
  • 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. +properties. This 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 : 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'
      +    }
      +});
      +

      + + +

      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
    +});
    +
    . +

    + +

Returns

  • void    +

enableBubble( +String/Array events) + : void
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.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');
+    }
+}
+});
+
+ +

sort( +String|Array sorters, String direction, Object where, Object doSort) + : void
Sorts the data in the Store by one or more of its properties. Example usage: + + +//sort by a single field +myStore.sort(...

Sorts the data in the Store by one or more of its properties. Example usage:

+ + +
//sort by a single field
+myStore.sort('myField', 'DESC');
+
+//sorting by multiple fields
+myStore.sort([
+    {
+        property : 'age',
+        direction: 'ASC'
+    },
+    {
+        property : 'name',
+        direction: 'DESC'
+    }
+]);
+
+ + +

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');
+
+ +

Parameters

  • sorters : String|Array

    Either a string name of one of the fields in this Store's configured Model, +or an Array of sorter configurations.

    +
  • direction : String

    The overall direction to sort the data by. Defaults to "ASC".
