[Mono-winforms-list] Howto mix WinForms and Cairo?

[Peter Dennis Bartok]

Yes, the handle that is returned by Control::Handle is of no use for using 
with cairo. There's usually a window right on top of the one this handle 
describes.

As I already answered before, to draw on our MWF windows, for best 
resultsSystem.Drawing should be used. We have no 'safety' locks and such to 
deal with someone outside of MWF drawing on our windows alongside us. If you 
try to own the whole window and do not expect MWF to draw, you'd need to set 
the appropriate styles on Control (AllPaintingInWmPaint and UserPaint), and 
get the Hwnd.Client handle via reflection to have the proper window do muck 
with.

Cheers,
  Peter
