Ext.data.ModelExt.grid.property.PropertyMixins
A specific Ext.data.Model type that represents a name/value pair and is made to work with the -Ext.grid.property.Grid. Typically, Properties do not need to be created directly as they can be -created implicitly by simply using the appropriate data configs either via the Ext.grid.property.Grid.source -config property or by calling Ext.grid.property.Grid.setSource. However, if the need arises, these records -can also be created explicitly as shown below. Example usage:
- -var rec = new Ext.grid.property.Property({
- name: 'birthday',
- value: Ext.Date.parse('17/06/1962', 'd/m/Y')
-});
-// Add record to an already populated grid
-grid.store.addSorted(rec);
-The name of the field treated as this Model's unique id (defaults to 'id').
-The name of the field treated as this Model's unique id (defaults to 'id').
-(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'); }
- }
- }
-});

A data object in the format:
- -{
- name: [name],
- value: [value]
-}The specified value's type -will be read automatically by the grid to determine the type of editor to use when displaying it.
-Adds the specified events to the list of events which this Observable may fire.
-Adds the specified events to the list of events which this Observable may fire.
-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.
[additional] Optional additional event names if multiple event names are being passed as separate parameters. -Usage:
- -this.addEvents('storeloaded', 'storecleared');
-Appends an event handler to this object.
-Appends an event handler to this object.
-The name of the event to listen for. May also be an object who's property names are event names. See
-The method the event invokes.
-(optional) The scope (this reference) in which the handler function is executed.
-If omitted, defaults to the object which fired the event.
(optional) An object containing handler configuration. -properties. This may contain any of the following properties:
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
-});

-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');
- }
-}
-});

-Gets all of the data from this Models loaded associations. -It does this recursively - for example if we have a User which -hasMany Orders, and each Order hasMany OrderItems, it will return an object like this: -{

-Generates a sequential id. This method is typically called when a record is created -and no id has been specified. The id will automatically be assigned -to the record. The returned id takes the form: -{PREFIX}-{AUTO_ID}.

-Static. Asynchronously loads a model instance by id. Sample usage:
- - MyApp.User = Ext.define('User', {
- extend: 'Ext.data.Model',
- fields: [
- {name: 'id', type: 'int'},
- {name: 'name', type: 'string'}

- //do something whether the load succeeded or failed
- }
- });

-Optional config object containing success, failure and callback functions, plus optional scope
-Sets observability on the passed class constructor.
- -This makes any event fired on any instance of the passed class also fire a single event through -the class allowing for central handling of events on many instances at once.
- -Usage:
