[gtkada] getting window positions

[Stephen Leake]

I'm running GtkAda 1.3.12 on Windows 98.

I'm trying to save some window positions in a file (actually a
Grace.Config_Files (http://savannah.nongnu.org/projects/grace/)), so
they are preserved across sessions.

I can set the window position with Widget.Set_UPosition.

But I can't figure out how to get the current window position.
Currently, I have:

Child_Pos_X : constant Glib.Gint  := Gtk.Widget.Get_Allocation_X (Widget);
Child_Pos_Y : constant Glib.Gint  := Gtk.Widget.Get_Allocation_Y (Widget);

But this always results in Child_Pos_X, Child_Pos_Y being 0. Widget is
a top-level window. Is this a bug? Is there a different function I
should use?

Another issue is what event to capture this in. Currently, I have it
in a handler for "delete_event". However, that is only called if the
user directly closes that window. My windows are children of the main
application window; if the user closes the main application window,
the child window "delete_event" handler is not called. Hmm, I guess I
need to call it directly, from the application window "delete_event".
Yuck; MS Windows does this better :).
