In the unlikely event, you will encounter the following problems: the QML window is stuck.
Please check if you: import pyside2, and use QmlApplicationEngine().load to load only one qml-vtk window(containing qmlRegisterType class) .
If you have to do this, plus self.createRenderer () to __ init__ function, fboitem class.
Then it works but an error window, vtkoutputwindow, will be displayed.
Then try to close the vtkoutputwindow (maybe call the Win32 API findwindow?)
Recommended solution: import PyQt5 instead of pyside2;
Or using QQuickView().setSource to load qml window;
Or load another independent general qml window before load the qml-vtk window.
