[osg-users] delete qwidget & removeView

[Sebastian Schmidt]

How can i safely delete a qwidget and remove the corresponding view from the compositeviewer at runtime?

At creation time i call setAttribute(Qt::WA_DeleteOnClose) and connect the destroyed() event of the widget with a function that just calls removeView().

After closing and opening the window several times it always crashes somewhere inside 
GraphicsWindowQt::swapBuffersImplementation()
where _widget is NULL.
