Hi Harash, Once the view is running its threads it isn't appropriate to dynamically add a new View, so what you need to do is call viewer.stopThreading(), add the view then call startThreading().
There is one proviso though, I haven't actually tried this with CompositeViewer yet, is still a pretty new class. If it doesn't work we'll need to modify the osgmultiplecameras example to do dynamic addition/removal of Views, then I can pick up the case at my end and tweak things so they work, be it modifications to the example or perhaps to the CompositeViewer implementation itself.

Hi Robert, Moving on the lines you had suggested, I have now been able to get a working MFC MDI Application with osgViewer::CompositeViewer. But there is an observation on this issue. The application I am developing requires a window to be dynamically opened / closed. The CompositeViewer class is expecting all the Views to be added before a call to frame() is made. If I make a call to osgViewer::CompositeViewer::frame(), then add a view using osgViewer::CompositeViewer::addView(), and again call frame(), the program hangs. Debugging, I found that this happens in osgViewer::renderingTraversal() .... if ( _startRenderingBarrier.valid()) _startRenderingBarrier->block(); The debugger gives the message: "This process seems to be deadlocked". I don't know if it is a bug or if the class is not supposed to be used in this manner. Please Help. Thanks in Advance. Regards Harash.

Further, as shown in osgMultipleCameras example, the traits structure was filled accordingly. The problem I am now facing is how to attach the MFC Window to the GraphicsContext / osgViewer. OSGMFC achieved this by passing the window handle using GetSafeHwnd() to Producer::RenderSurface. But I could not locate a mechanism of passing any such information to the osgViewer::View or CompositeViewer or Viewer. One Win32WindowingSystemInterface class I could locate, but there too I could not find a way out. I don't have the code to hand, but if your browse through the osg-users email archives for the last week you'll see how to use the osg::GraphicsContext::Traits::inheritedWindowData set to osgViewer::GraphicsWindowWin32::WindowData(hwnd) to tell the viewer to realize a window adopting the passed in window. The approach is roughly the same as done in Producer::RenderSurface previous, only the architecture is a bit different in osgViewer.
