All Qt enums have been declared as classes inheriting from enum.Enum . This covers many of the use cases of using Qt enums in python, but fails one (from typing point of view) : getting the enum value.

For example, I have some code like this :

def some_func() -> int;

    ret: int

    p = QProcess()

    [run qprocess] 

    if p.exitStatus() != QProcess.ExitStatus.NormalExit:

        ret = p.exitStatus().value

    else:

        ret = p.exitCode()

    return ret

Getting the value of p.exitStatus() will not type correctly because it enum.Enum values have not type specified.

Proposition: instead of using Enum as your base class for Qt enum, use IntEnum . This will reflect the practical reality, all Qt enum are actually int enum. And this will type correctly.

I tested it successfully in PySide6-stubs:

    class ExitStatus(enum.IntEnum):

        NormalExit              = 0x0
        CrashExit                = 0x1

Note that contrary to my title, using IntEnum is not sufficient. You have to actually provide a value or declare explicitely the enum as int :

    class ExitStatus(enum.IntEnum):

        NormalExit   : int     = ... # 0x0
        CrashExit      : int     = ... # 0x1
