I think the 'recommended" way to provide the custom behaviour 
of TCanvas is to supply a custom implementation of TCanvasImp 
base class. (see Go4 and ActiveRoot projects for examples)

But if you do want to get a handle to the HWND (at least in win32) I
think
you can cast the TCanvasImp into a TWin32Canvas which has a GetWindow()
method that returns the HWND.

My question is the following.  Can you turn off the menubar and border
for
canvas and then wrap it in a CWnd (MFC) via the HWND?
