Class Roo.ViewPanel

Parameters:

Object object

The object with the events defined

Parameters:

String eventName

The type of event to listen for

Function handler

The method the event invokes

Object scope

(optional) The scope in which to execute the handler
function. The handler function's "this" context.

Object options

(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 {link Roo.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
		});
		

layout.addxtype({
       xtype : 'Form',
       items: [ .... ]
   }
);

Parameters:

Object/String/Function url

The url for this request or a function to call to get the url or a config object containing any of the following options:

panel.load({
    url: "your-url.php",
    params: {param1: "foo", param2: "bar"}, // or a URL encoded string
    callback: yourFunction,
    scope: yourObject, //(optional scope)
    discardUrl: false,
    nocache: false,
    text: "Loading...",
    timeout: 30,

are shorthand for disableCaching, indicatorText and loadScripts and are used to set their associated property on this panel UpdateManager instance.
