Depends upon what you need. Do you need the X11 window handle or the graphics
context? The display pointer? The "Handle" property on a control should
work in the Win32 version of pnet winforms to get the HWND, but returns
IntPtr.Zero in the X11 version.
It is possible to get it via a round-about method. "Graphics.Hdc" will return
a GC handle that can be used to access the "Xsharp.Graphics" object
underneath a control (see the code in
System.Drawing.Xsharp/DrawingGraphics.cs for details). From this, you can
get the drawable handle, display pointer, and other X11 details.
The current interface is perhaps a little awkward, and could be improved by
returning the drawable handle from "Control.Handle", if that's what you need.
Cheers,
Rhys.
