Re: [gtkmm] Is it possible to add widgets to a drawingarea?

[Joonas Kiviharju <satelliittipupu yahoo co uk>]

I've heard about GnomeCanvas, and that it's better
than a plain Gtk::DrawingArea, BUT isn't GnomeCanvas
platform dependant? It seems to me you can only use it
for Linux?

Ofcourse I could drop windows and OS X from being
supported, but... if there's any way of doing it in a
platform independant way?

Well, maybe I'll just drop this whole OpenGL, platform
independant timeline anyway, and do just a standard
Gnome-program, and hope that in the future my app can
be ported...
