Re: [osg-users] switch off mouse press events

Hi Sujan, what you are describing is the normal behavior of the Trackball CameraManipulator. There are many ways how you can change processing of mouse events. Either remove the CameraManipulator (view-getCamera()-setCameraManipulator(0)) or inherit from the one CameraMainpulator that most suit
