I think what you need is to use the macro:


Note that you will need to wrap the macro in a C function, and p/invoke
to it. Then, from C#/Gtk#, you can write code like:

Window window = ...;
int id = gdk_drawable_xid(window);

I would guess you will also need the xdisplay, even if you system
handles the GLContext. Use the macro:


You can take a look in the CVS of GtkGL# (module "gtkgl-sharp", password


(btw, you need to export CVS_RSH=SSH).
