OpenGL in Gtk# or Windows Forms

Hi! I’m new in using OpenGl as a component of an existing c#-gui (no standalone-window). please can anybody give me a short example, how I can embed an opengl-panel on a gtk#- or windows form-gui? I’m using mono.

Thx, Peter

With default gtk+, this is gtkglext, with gtkmm (C++), this is gtkglextmm. Should be the same if the port has been made.
