Re: [gtk-win32] Object Handle

[Jerome Haltom <wasabi larvalstage net>]

I have managed to successfully put a Windows .Net
System.Windows.Forms.Control into a Gtk# top level window. It wasn't
really that hard.

Basically I created a Gtk# widget, grabbed it's hWnd, the reparented the
WinForm control into it. It really wasn't hard. This works when using a
Gtk main loop as it draws from the Win32 message pump. For the reverse,
I'm not so sure.

I doubt the experience would be much different using Win32 instead
of .Net.

What is hard is getting layout to work, and propagating size changes to
the control in a meaningful manner.
