Hi Stephan, thank you for your suggestion. I tried to create windata by passing the app's window, set the traits to what I need, but I get 'noise' in the window area outside the intended viewer's view.
Instead, if I pass a custom UIView object then the viewer's view is created as described earlier (and no noise in the window's area not covered by the view). But in this case the viewer's view is not added to the window's subviews, and it is not added even to the UIView I passed when creating the windata object. Instead it is added to the parent of the UIView object I intended to use. Now, I can try to think about a way to safely get a reference to the view object created by OSG, it could be useful to have a way(method) to do it straight from OSG's APIs. What do you think? Cheers.
