Re: [GtkGLExt] Multiple view problem

["Jordi Rovira" <caminant gmail com>]

Hi,

  I've found the problem already. I was missing the
gldrawable->gl_begin(get_gl_context()) in the expose event handler!
A copy and paste problem, as i have verified the gears.cc example i
used as reference and it is correct there.

  Thanks.

I would throw some printf statements into your handlers and see whether
the configure and expose events are being received the way you think.
This may be a subtlety of the way the Gtk::Paned widget works, you may
need to experiment with the parameters to the pack1() and pack2()
methods.

Cheers,
Tim
