Welcome to the forums!
But seriously, it’s because you declared a mouseWatcher pointer but never assigned it to anything. So you’re trying to dereference an uninitialised pointer.
Thanks rdb, I add:
mouseWatcher=new MouseWatcher();
to main(), now I don’t have segfault, but mouseWatcher don’t react on mouse. I need to set mouseWatcher to watch window or something?
Sorry for newbie questions.
You need to use the existing MouseWatcher node, that you can retrieve by calling get_mouse().node() on the WindowFramework object.
I change to:
mouseWatcher = DCAST(MouseWatcher, window->get_mouse().node());
and now all works. Thank you rdb!
