Property Details

disabled

public Object disabled

true if this component is disabled. Read-only.

This property is defined by Component.

hidden

public Object hidden

true if this component is hidden. Read-only.

This property is defined by Component.

rendered

public Object rendered

true if this component has been rendered. Read-only.

This property is defined by Component.

Constructor Details

DateField

public function DateField( Object config )

Create a new DateField

Parameters:

config : Object

Method Details

addEvents

public function addEvents( Object object )

Used to define events on this Observable

Parameters:

object : Object
The object with the events defined

Returns:

void

This method is defined by Observable.

addListener

public function addListener( String eventName, Function handler, [Object scope], [Object options] )

Appends an event handler to this component

Parameters:

eventName : String
The type of event to listen for
handler : Function
The method the event invokes
scope : Object
(optional) The scope in which to execute the handler function. The handler function's "this" context.
options : Object
(optional) An object containing handler configuration properties. This may contain any of the following properties:
- scope {Object} The scope in which to execute the handler function. The handler function's "this" context.
- delay {Number} The number of milliseconds to delay the invocation of the handler after te 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.
Combining Options
Using the options argument, it is possible to combine different types of listeners:

A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
```
el.on('click', this.onClick, this, {
 			single: true,
    		delay: 100,
    		forumId: 4
		});
```
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 handlers.
```
el.on({
			'click': {
        		fn: this.onClick,
        		scope: this,
        		delay: 100
    		}, 
    		'mouseover': {
        		fn: this.onMouseOver,
        		scope: this
    		},
    		'mouseout': {
        		fn: this.onMouseOut,
        		scope: this
    		}
		});
```
Or a shorthand syntax which passes the same scope object to all handlers:
```
el.on({
			'click': this.onClick,
    		'mouseover': this.onMouseOver,
    		'mouseout': this.onMouseOut,
    		scope: this
