Thanks J-S I will be getting to grips with Vista 64bit shortly ... My PC died last week taking the mother board and drive with it, so I took the bullet can still role back to XP if I really dislike it... At the end of the day for windows developers were most of my work is you cannot really avoid for much longer..

Most of the time when testing I will add -- window 50 50 1024 768 so I get a nice window instead of fullscreen. > Also when we come out of full screen with osgViewer we get multiple > windows, we all work with multi-headed PC's, any way to make it single > windowed as the multi-windowed version annoying for us ;), its not > critical as I only use the viewer for some comparison tests You can use OSG_SCREEN x for a single fullscreen viewer on screen x, or if you're using osgViewer::Viewer you can call setUpViewOnSingleScreen(x) to get the same effect, as Paul said. Note that currently, on Vista, when using that method (or OSG_SCREEN), you will get the fullscreen view on screen x, and your other screen(s) will be black. This is a bug resulting from the new Vista driver model, which should be fixed. I'm just waiting to get a bit of time from our tight deadlines to help fix it. On XP it works properly (there is a fullscreen viewer on screen x and nothing on the other screen(s), i.e. you see your other windows and the screen(s) don't turn black). So to summarize: osgviewer with no command line arguments and no env variables is the same as osgViewer::View::setUpViewAcrossAllScreens(). osgviewer with either OSG_WINDOW x y w h in the environment or --window x y w h on the command line is the same as osgViewer::View::setUpViewInWindow(screen, x, y, w, h) where screen will be 0 by default or OSG_SCREEN if set. osgviewer with OSG_SCREEN x in the environment (there should probably be a command line argument for this too) is the same as osgViewer::View::setUpViewOnSingleScreen(x). So if you ever want to do custom window setups for your app, looking at the source of the above methods is a great help. Also note that if you're using osgViewer::CompositeViewer, when you create a new osgViewer::View to add to it you can still call these methods as quick shortcuts to get some standard window setup. It's a good design! A little plug for Paul's book: while typing this up, I was looking up the env vars in the OSG Reference Manual v2.2 :-) Hope this helps, J-S -- ______________________________________________________ Jean-Sébastien Guay [EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
