Easy: As I mentioned the button must be layouted and visible first. At
the moment you call ''getBounds'' it is only a in-memory widget. Nothing
applied to the DOM yet.
You can listen for the resize event as the resize event is the first
time the widget is layouted:
button1.addListener("resize", function(e) {
alert(this.getBounds());
});
