Hi Robert, sorry for my late reply, but your posting didn't make it to the gmane newsgroup which I am using. So I'll give the forum a try :-)
I didn't modify the OSG code because we're using various installations here (windows and linux). The WindowManager has a memeber EventInterface* _lastEvent which tracks the last EventInterface (i.e. Widget) that received a mouse event (ENTER, PUSH, ....). If a new mouse event is received, the WindowManager checks if he should send a mouse LEAVE event to the widget stored in _lastEvent. What I do, is that I initially focus the widgets/menus via mouse, but then use keyboard interaction to select items and that interaction my replace all widgets in the menu list by new ones. So when I after that move the mouse again, WindowManager tries to send a mouse LEAVE to _lastEvent which at that mpoint may be an invalid pointer. So my idea was to just use osg::ref_ptr<EventInterface> _lastEvent instead and do some additional _lastEvent.valid() checks. But since I'm not too familiar with the internals of the WindowManager I don't know exactly what implications this would have. In our own code, we are just forwarding the WindowManagers mouse and keyboard event to our own listener classes, so I just added a ref_ptr there, so that I have a "backup" of the original widget that is stored in WindowManager::_lastEvent so that the WM can call whatever function he wants. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=14805#14805 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
