... child window doesn't hide

[Antonio Coralles <noche suapie reflex at>]

i've a class derived from Gtk::Window, and in this class lies an object 
of a class which is also derived from Gtk::Window. now, when a button in 
my  main window is pressed, show() is called for my child window, and it 
shows up .... the problem is, that it doen't disapear again when i click 
on close, or eaven on a button on this window directly connected with 
hide(). i've allready tried to unset the Gtk::TOPLEVEL flag - but that 
just resulted in lot's of gtk warnings and a subwindow not recognizing 
my desktop theme ... then i've tried Gtk::Window(/Gtk::WINDOW_POPUP/), 
but this is not what i want because it removes the standard buttons (so 
i didn't test it) .

maybe someone can give me a hint ...
