GWT MouseOut event on a Composite

I have:

1. created a Composite,
2. initWidget-ed with an AbsolutePanel
3. added some Widgets to the Composite
4. in the Composite constructor attached a MouseOut handler

What I wanted to reach is detecting when the mouse is out of th开发者_如何学编程e Composite (or AbsolutePanel), but the MouseOut handler is fired whenever the mouse is out of any wideget in the AbsolutePanel.

Is there any clean way I can reach detecting the AbsolutePanel out?

The GWT I'm using is 2.0, with no add-ons (and I don't want to use any).

OK, I've found a solution.

I extended the AbsolutePanel class, so that implements HasMouseoutHandlers. Now, instead of adding MouseHandler to the Composite, I add it to the MyAbsolutePanel only. This works fine.
