    Question about the performance of the listeners and the handler


    Hi,

    I like to know, if I need a click event what do I need to use. the listeners or the handler?

    Does the listeners take more performance?

    Thanks,
    Noam

    handler is linked to button//menu
    if you're looking on source code you can found the answer of your "question" :
    PHP Code:
        // private method of Ext.Button = Ext.extend(Ext.BoxComponent,...
        
    onClick : function(e){
                .......
                
    this.fireEvent('click'thise);
                if(
    this.handler){
                    
    //this.el.removeClass('x-btn-over');
                    
    this.handler.call(this.scope || thisthise);
                }
            }
        }, 
    I hope that this source code give to you some comprehension information !
    For me, the only good information that have some interest, is that click event is called before handler method ))

    I'm sorry for the misunderstanding, I have to be sure.
    The example you give is proving that handler is better, right (when we lisen to 'click' event)?
