You should have something like this:

gtk_widget_set_events (GTK_WIDGET (gl_area), GDK_EXPOSURE_MASK |
GDK_BUTTON_PRESS_MASK | GDK_BUTTON_RELEASE_MASK |
GDK_POINTER_MOTION_MASK | GDK_POINTER_MOTION_HINT_MASK |
GDK_KEY_PRESS_MASK | GDK_KEY_RELEASE_MASK);

The location might be critical, put it before the
X window is actually created, say immediately after
gtk_gl_area_new ().
