Look for notify on the "position" property:

        g_signal_connect( pane, "notify::position",
                G_CALLBACK( pane_notify_position_cb ), NULL );

Took me ages to work this out as well :-( Here's a widget that wraps
up a pane as a side panel that can slide in and out:

http://vips.svn.sourceforge.net/viewvc/vips/nip2/trunk/src/pane.c?revision=121&view=markup

It remembers the position, has a simple hide/reveal animation, and
knows whether it's currently open or closed.
