Effectively, gdk_window is NULL.

Thanks

I think this is a way to hide the cursor:

Glib::RefPtr<Gdk::Window> gdk_window = fenetre.get_window(); if (gdk_window)
   gdk_window->set_cursor(Gdk::Cursor::create(Gdk::BLANK_CURSOR));

A possible complication is that Gtk::Widget::get_window() returns a Gdk::Window pointer only if the widget has been realized, and I don't know when exactly that's done.
