Hi,
you can rewrite it to:
this._yourButton.addListener("execute", this._onExecute, this);
and in your class you should create _onExecute member function:
_onExecute: function(ev)
{
// do something useful...
}
or you can of course pass this to inline event handler:
this._yourButton.addListener("execute", function(ev) {
this.thisIsStillValid();
}, this);
Important is third argument - 'this'.
Just forget the way used in other libraries like jQuery, etc. In
qooxdoo you have real object oriented design and you can really
connect objects together:)
