Does your callback routine expect this gpointer as its second or third
argument?  Some signals will pass this back as the 2nd parameter to your
callback, others pass it back as the 3rd.  In the latter case the 2nd arg
is actually a pointer to an GtkEvent  structure so you can tell what event
actually caused the callback to be called.
