Hello, I'm trying to use the mouse scroll button as if it was the right mouse button. All I want to do is move the camera closer and further with the mouse scroll button... The problem is that I don't receive the events by just moving the scroll. In order to get the event I need to press a button (either keyboard or mouse), once a button is pressed I will get all the events in the queue.
Has anyone done something like this? Here is the code from my modified trackball manipulator: bool handle(const osgGA::GUIEventAdapter& ea,osgGA::GUIActionAdapter& us) { switch(ea.getEventType()) { case(osgGA::GUIEventAdapter::FRAME): if (_thrown) { if (calcMovement()) us.requestRedraw(); } return false; default: break; } if (ea.getHandled()) return false; switch(ea.getEventType()) { case(osgGA::GUIEventAdapter::PUSH): { flushMouseEventStack(); addMouseEvent(ea); if (calcMovement()) us.requestRedraw(); us.requestContinuousUpdate(false); _thrown = false; return true; } case(osgGA::GUIEventAdapter::SCROLL): { int x = 0; //Here I have a brakpoint :) //_distance += 100.0f; return true; } // case(osgGA::GUIEventAdapter::KEYDOWN): if (ea.getKey()== osgGA::GUIEventAdapter::KEY_Space) { flushMouseEventStack(); _thrown = false; home(ea,us); return true; } return false; Thank you very much
