Re: [GtkGLExt] gtkglext cannot draw geometries (jiangtengfei)

    Hi,
        You need to tell GTK that the draw rectangle is 'dirty' (has 
been updated) after your "gdk_gl_drawable_gl_end (gldrawable)" with this 
function call:

gdk_window_invalidate_rect (gtk_widget_get_parent_window (widget), 
&widget->allocation, TRUE);


Regards,
            Jose.
