Hi,
I've just started using GTK and GtkGLArea imparticular, and I've got a problem with
signals...
I have a callback that is responsible for redrawing the glarea widget when it receives
an "expose_event" signal, which works fine when just resizing the
window etc. But I also want a mouse motion

Make sure that you're calling
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT )
somewhere before the image is display. Calling this
in the configure_event handler (called when the window is resized,
and also the first time before mapping) seems to work for me.
Good luck,
