I agree it is a very good solution.  The fact that you get multiple handles
refering to different parts of the form is annoying... and may break API
stuff that sets a windowed controls parent handle to be the parent form's
handle.... but hey this API stuff usually goes on INSIDE components not
applications and components will take some porting.  Besides there is no
reason to expect the API widget routines and handles uses to be nearly
similar to the windows API model.

Err... do child widgets also have a fixed widget attached when they have a
child widget added?  I mean is this TWinControl behaviour or just TForm
behaviour.  I think it should be TWinControl behaviour.

If they are of widget type container.



Does GTK have any z order functions?  Does it even have z order (Surely it
must have...)
Perhaps the order is the gtk-add'd order?
