Multiple Ext.Button handlers

[DavorZ]

is there a way to put multiple handlers on a button, so it starts multiple functions at once??
something like, open all button??

Ext.onReady(function() {

    var myButtonAll = new Ext.Button({

        text       : "OPEN ALL",
        handler    : varname, varname...???
        renderTo   : "buttons",
        scale      : "large",
        iconCls    : "button_two",
        width      : 100,
        height     : 100,
 
    
    });
        

});

Since the "handler" config option just assigns the function to the click event of the button... you can add multiple click events to your button like this:

Ext.onReady(function() {
    var myButtonAll = new Ext.Button({
        text       : "OPEN ALL",
        handler    : varname, varname...???
        renderTo   : "buttons",
        scale      : "large",
        iconCls    : "button_two",
        width      : 100,
        height     : 100,
    });
    myButtonAll.on('click', handler1);
    myButtonAll.on('click', handler2);
    myButtonAll.on('click', handler3);
    myButtonAll.on('click', handler4);
});

Or you can wrap all of them in an anonymous function like this:

Ext.onReady(function() {
    var myButtonAll = new Ext.Button({
        text       : "OPEN ALL",
        handler    : function() {
                        handler1.apply(this, arguments);
                        handler2.apply(this, arguments);
                        handler3.apply(this, arguments);
                        handler4.apply(this, arguments);
                    }
        renderTo   : "buttons",
        scale      : "large",
        iconCls    : "button_two",
        width      : 100,
        height     : 100,
    });
});

And the handlers should have the signature of the button click handler, for example:

handler1 = function(button, event) {...}

You don't need to be an anonymous function. Adding multiple event listeners will affect performance. Best way to do it is have a wrapping function.
