A quick check of the documentation turned up gdk_window_get_device_position(), which should work even outside mouse events. (I have not tried it myself.) The caveat here is that this is for GDK windows, not what most people think of as windows (i.e. GTK+ windows). One path from a GTK+ widget to a GDK window is gtk_widget_get_window().
