Dear All,I need to switch off the camera manipulator in one of the views in
composite viewer. Setting the view->setCameraManipulator(NULL); doesn't work
in my case, setting camera manipulator to the 0 value doesn't help also.
Furthermore, having calling the
view->getCamera()->setProjectionMatrixAsOrtho2D(-newx,newx,-newy,newy);in each
scrolling doesn't cause any wreak havoc or any performance penalty, right?
case ( osgGA::GUIEventAdapter::MOVE): { newx
= ea.getX(); newy = ea.getY(); break; }
case (osgGA::GUIEventAdapter::SCROLL): {
osgGA::GUIEventAdapter::ScrollingMotion sm = ea.getScrollingMotion();
switch (sm) { case
osgGA::GUIEventAdapter::SCROLL_UP : {
newx -=5; newy -=5;
view->getCamera()->setProjectionMatrixAsOrtho2D(-newx,newx,-newy,newy);
break;
}
case(osgGA::GUIEventAdapter::SCROLL_DOWN): {
newx += 5; newy +=5;
view->getCamera()->setProjectionMatrixAsOrtho2D(-newx,newx,-newy,newy);
break; } }
//
view->getCamera()->setProjectionMatrixAsOrtho2D(-newx,newx,-newy,newy);
