Re: [osg-users] How to capture Keyboard event in OpenSceneGraph

Hi Dat, I recommend you to peruse the osgkeyboard.cpp file that comes with the source code examples (specifically the classes KeyboardEventHandler and osgGA::GUIEventHandler), and to upgrade to a more recent OSG version (at least 2.6.0). Regards, Alberto El Miércoles 21 Enero 2009ES
