Hi!
I've been trying to insert the GtkGlarea widget into code generated by
Glade. I works just fine as long as there isn't any other widgets in the
window for exampel menus or buttons. But when there is i get the
following runtime error message:

** CRITICAL **: file gtkglarea.c: line 184 (gtk_gl_area_make_current):
assertion `GTK_WIDGET_REALIZED(gl_area)' failed.

Gdk-CRITICAL **: file gdkwindow.c: line 716 (gdk_window_ref): assertion
`window != NULL' failed.

Gdk-CRITICAL **: file gdkwindow.c: line 716 (gdk_window_ref): assertion
`window != NULL' failed.

Can somebody please explain this to me?

Thanks!
