Constructor Details

TreeNode

public function TreeNode( Object/String attributes )
Parameters:
  • attributes : Object/String
    The attributes/config for the node or just a string with the text for the node

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
		});
