I am developing some status screen GUIs using QtCreator and am using PyQtGraph widgets in various places (multi-Hz image displays with HIstogramLutWidgets). In this case I am using a GLViewWidget and instantiating a GLSurfacePlotItem in it. If the GLViewWidget is embedded in a QStackedWidget ot QTabWidget it appears in its own separate window when I run the GUI, and its tabbed or stacked widget in the GUI is blank. If I embed the GLViewWidget in a simple QFrame then the GLSurfacePlotItem appears within the QFRame as expected.
Has anyone else experienced this and can provide any help?
