Jens, They way I use the widgets, maybe not supported, work perfectly. It is made part of the widget hierarchy. And when I remove the widget, everything is again cleaned up. I did a lot of memory leak investigating and it is just working the way it should. Even if the window close event is triggered, they get properly cleaned up just like the rest of the widget hierarchy.
The wrap methods on Widget assume and do too much and that makes them not usable beyond the scope of wrapping non nested widgets.
