[paragui-users] SetTitle(), ~ListBox(), ~PG_Window()

[H. C.]

Hi!
Apparently, my last message was "eaten" by the mailing list. Nevertheless,
here's an updated one:
SetTitle() should Update() the titlebar's buttons, since they'll be hidden
as soon as one calls SetTitle().
Finally, I have two questions:
Shouldn't PG_ListBox's destructor contain the same things PG_WidgetList's
does?
Shouldn't the destructor of PG_Window delete all of its buttons?
Many thanks in advance!
