There are some missing parts in osg::GraphicsContext::WindowingSystemInterface to report the relative position of a screen in relation to the other screens / main screen. Without that information, it's hard to compute a correct window-layout. > 2 - osgGA::GUIEventAdapter::ScrollingMotion > > I'm trying to write my own camera manipulator.

Scrolling-Events with modern input (touchpad, magic mouse) produce SCROLL_2D-events, if you attach a mouse with an old scroll-wheel, you'll get SCROLL_DOWN/_UP-events. The bug/missing feature lies in StandardManipulator not handling SCROLL_2D-events correctly. Feel free to implement them and submit it back to the community. > 3 - osgGA::GUIActionAdapter requestWarpPointer() > > I'm trying to keep the mouse cursor always in the middle of the screen > which works as expected.

Have you tried the suggested fixes in the mentioned thread? Did they work? If so can you prepare a submission for osg-submission? cheers, Stephan _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
