QStateMachine is missed on pyside6 Linux version

Roger Huang

@All,

Used QStateMachine and related classes are not working at pyside6 linux version.
Below is my error messages after running example code " python eventtrans.py" under PySide6/examples/widgets/state-machine folder:

Traceback (most recent call last):
  File "eventtrans.py", line 91, in <module>
    mainWin = MainWindow()
  File "eventtrans.py", line 52, in __init__
    machine = QStateMachine(self)
NameError: name 'QStateMachine' is not defined

Another functions is work fine. e.g. show main window of pyside6.

My OS: Ubuntu 20.04
Python: 3.8.6 with virtual environment

Has any suggestion?

Hi and welcome to devnet,

How are you importing that class in your code ?

@Roger-Huang As I see in the comments of https://www.qt.io/blog/add-on-support-in-qt-6.0-and-beyond:

Maurice Kalinowski[moderator]
The state machine framework has been moved to Qt ScXML, which again will be renamed to Qt State machine, as it incorporates both engines.
From above list, it will be part of 6.1.

So probably when Qt ScXML is implemented in Qt 6.1 then it will be available in PySide6 6.1.0

Thanks your info.

Yes, after upgrade to 6.1.0 the demo code can work correct.
