Hello,
it works! I'm very happy now. It was another mistake.
I have write my EventHandler and call the handle-method of the manipulator in
the handle method of my handler. That was the first idea of Jean-Sebastien. My
problem was I had define another event handler above and this makes problems
for my second event handler.
bool handle(const osgGA::GUIEventAdapter& ea,osgGA::GUIActionAdapter& us)
{
switch(ea.getEventType())
{
case(osgGA::GUIEventAdapter::FRAME):
_activeViewport = getActiveViewport(ea);
_tm = _viewports[_activeViewport]->getManipulator();
_viewports[_activeViewport]->setViewMatrix(_tm->getInverseMatrix());
}
return _tm->handle(ea,us);
}
That is my solution.
Cheers
Martin
