pyqt - 如何在 PyQt5 中获取 QEvent 的字符串名称

Question

在 PyQt 下，我正在为 Qt Events 计时，我想用时间写一个人类可读的字符串名称。使用 PySide2 时，只需调用 str() 即可获得字符串名称，但使用 PyQt5 时，它会返回一个作为枚举值的字符串:

# PySide2
>>> str(QEvent.KeyPress)
'PySide2.QtCore.QEvent.Type.KeyPress'

# PyQt5
>>> str(QEvent.KeyPress)
'6'

有没有办法使用 PyQt5 获取字符串名称？我可以发布一个在启动时构建查找表的解决方案，这可行，但想知道是否有直接的方法。

这就是我用来记录发生在我的 QWidget 子类上的事件的方法。刚刚从文档中制作了查找表 https://doc.qt.io/qt-5/qevent.html

def event(self, event: QtCore.QEvent) -> bool:
    print(event_lookup[str(event.type())])
    return super().event(event)

event_lookup = {"0": "QEvent::None",
                "114": "QEvent::ActionAdded",
                "113": "QEvent::ActionChanged",
