Here is a minimal program that demonstrates the issue. OSG 3.2: the mouse scroll wheel works in the inset view; all other mouse events "pass through" to the underlying view.
OSG 3.1.4: works as expected. #include <osgViewer/CompositeViewer> #include <osgDB/ReadFile> int main(int argc, char** argv) { osg::ArgumentParser arguments(&argc,argv); osg::Node* node = osgDB::readNodeFiles(arguments); if ( !node ) return -1; osgViewer::CompositeViewer cv( arguments ); osgViewer::View* mainview = new osgViewer::View(); mainview->setUpViewInWindow( 100, 100, 1600, 1024 ); mainview->setSceneData( node ); cv.addView( mainview ); osg::GraphicsContext* gc = mainview->getCamera()->getGraphicsContext(); osg::Camera* camera = new osg::Camera(); camera->setGraphicsContext( gc ); camera->setViewport( 20, 20, 700, 500 ); camera->setProjectionMatrixAsPerspective( 45.0, 7.0/5.0, 1.0, 1e6 ); osgViewer::View* insetview = new osgViewer::View(); insetview->setCamera( camera ); insetview->setSceneData( node ); cv.addView( insetview ); cv.run(); } Glenn Waldron / @glennwaldron On Fri, Nov 1, 2013 at 3:47 PM, Glenn Waldron <gwald...@gmail.com> wrote: > Hi folks, > > I have an app that uses a CompositeViewer with one "Master" View that > fills the window and multiple "inset" Views that sit on top of the main > View.
