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();
}
