Thanks Kjell!

What I see is, that the hide signal is delegated to some "other"
instance which calls the delete.


window->signal_hide().connect(sigc::bind<Gtk::Window*>(sigc::mem_fun(*this,
     &ExampleApplication::on_window_hide), window));

  void ExampleApplication::on_window_hide(Gtk::Window* window) {
delete window; }

My question still is: Is it safe to delete the "own" window the the
"own" signal handler and which signal handler is best to use for the
call to delete. Is it either on_hide() or on_delete_event( GdkEventAny* );

Thanks!
