Hi All, I implemented a PointPicker derived from osgGA::GUIEventHandler and overloading:
virtual bool handle(const osgGA::GUIEventAdapter& ea,osgGA::GUIActionAdapter& aa, osg::Object*, osg::NodeVisitor*); in which I handle both osgGA::GUIEventAdapter::PUSH and osgGA::GUIEventAdapter::RELEASE cases and always return false. In my Qt application I have a ViewerWidget that inherits from osgQt::GLWidget and osgViewer::CompositeViewer. All key events ara handled in ViewerWidget by overloading keyPressEvent(QKeyEvent*). Now, I thought to activate the PointPicker by pressing 'C' key. So for "Qt::Key_C" key I call: getView(0)->addEventHandler(pointPicker); Since the point picker must be deactivated after the first pick, then I thought to handle the mouse release event on the ViewerWidget side also, overloading the method mouseReleaseEvent: ViewerWidget::mouseReleaseEvent(QMouseEvent* event) where I call: superclass::mouseReleaseEvent(event); getView(0)->removeEventHandler(pointPicker); The problem is that when removeEventHandler is called the event has not been already processed by PointPiker::handle(...). So osgGA::GUIEventAdapter::RELEASE case never happens. I tryed to call eventTraversal() as follows: superclass::mouseReleaseEvent(event); eventTraversal(); getView(0)->removeEventHandler(pointPicker); but unfortunately it does not solve the problem. I found a workaround but I will appreciate if someone could explain how to solve this case.
