Hi Oliver, These are pure Producer question, so based asked on the Producer-users mailing list.

Hi, I have two questions concerning closing a window which uses the Producer::RenderSurface. 1. I wrote a class which has a camera, a rendersurface and a render context. Its task is to display images which will be drawn to the render context by using glDrawPixels. I set it up like this: osg::ref_ptr<Producer::Camera> _camera = new Producer::Camera(); osg::ref_ptr<Producer::RenderSurface> _renderSurface = new Producer::RenderSurface(); osg::ref_ptr<ImagePreviewContext> _imagePreviewContext = new ImagePreviewContext(); // _imagePreviewContext inherits the Producer::Camera::SceneHandler and overwrites the draw() method, where glDrawPixels is called. // setup the draw camera _camera->setRenderSurface(_renderSurface.get()); _camera->setSceneHandler(_imagePreviewContext.get()); // set default size (256 x 256) _renderSurface->setWindowRectangle(0, 0, 256, 256); Now my question: How can I close the window without using the close button of the window. I want to destroy my object dynamically by method calls with all variables and I want it to be closed automatically. My destructor looks like this: _camera.release(); _renderSurface.release(); _imagePreviewContext.release(); But the window is still there. It is not updated anymore, but the window with the borders is still there. The last point leads to my 2nd question. 2. What is the best way to delete ref_ptr objects? _camera.release() or _camera.unref() or another way, which I don't know yet? regards, Oliver _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
