Well these are two separate concepts; what the OP was asking about would 
be done with SetWindowRgn() and family on Windows. There is an example 
of that, as mentioned before, in the wheelbarrow demo. For gtkmm: 
http://www.gtkmm.org/gtkmm2/examples/window/wheelbarrow.cc. I assume 
that with 'owner drawn' controls you mean 'custom controls with their 
own WndProc that handle all messages themselves, including WM_PAINT'. 
That can be done in gtk/gtkmm with 'custom controls', see the gtkmm 
documentation.
