Re: [gtkmm] Change cursor in Widget (fwd)

[Sergio Pascual <spr astrax fis ucm es>]

Now it works, with the call to Gtk::Window::on_realize() before the call 
to the cursor functions

virtual void on_realize(){
                Gtk::Window::on_realize();
                Gdk::Cursor cursor(Gdk::STAR);
                get_window()->set_cursor(cursor);
}

Thanks

Sergio, if you place
         Gtk::Window::on_realize()
here, your code should work.
