Help: Ext.Element on method

[java9394]

From the example on the Manual:Intro:Event Handling page:

var el = Ext.get('somelink');
el.on('click', function(){
alert('you click on a link');
});

I wonder where this "on" method inherited from. I checked the API doc, but I didn't see the "on" there :-?

thnx.

It's a shortcut to Element::addListener method
Element.js line 2681

ep.on = ep.addListener;

actually I believe it comes from Ext.util.Observable;

Not quite, because Ext.Element doesn't inherit from Observable, see:



addListener : function(eventName, fn, scope, options){
Ext.EventManager.on(this.dom, eventName, fn, scope || this, options);
},


Makes a call directly to the event manager.

You are wrong Ext.Element isn't a child of Ext.util.Observable.

Well thats one thing that is very hard to do in the docs; trace inheritance. I tried.
