Seems to be the addItem (sp2), there is something wrong with initializeGL
If hasattr (item, 'initializeGL) :
Self. MakeCurrent ()
Try:
Item. InitializeGL ()
Except:
Self. CheckOpenGLVersion (' Error while adding item % s to GLViewWidget. '% STR (item))
For a great god ever encountered similar problems, how to solve? Thank you very much!
