Under PyQt 我在时间上很晚,我想写一个可以读写的人名。 有了PySide2,我只打电话str>,就给我写明了名字,但用PyQt5,则用大体表示:
# PySide2
>>> str(QEvent.KeyPress)
PySide2.QtCore.QEvent.Type.KeyPress
# PyQt5
>>> str(QEvent.KeyPress)
6
是否有办法利用PyQt5获得拼凑的名称? 我可以提出一个解决方案,就启动问题,即这项工作,但想知道是否有直接途径。
http://code>PyQt5和PySide2。 I m 只是通过在<代码>中列举每一类事件而形成一个字典。 QEvent Object. 但我想到的是更多的东西。
class EventTypes:
"""Stores a string name for each event type.
With PySide2 str() on the event type gives a nice string name,
but with PyQt5 it does not. So this method works with both systems.
"""
def __init__(self):
"""Create mapping for all known event types."""
self.string_name = {}
for name in vars(QEvent):
attribute = getattr(QEvent, name)
if type(attribute) == QEvent.Type:
self.string_name[attribute] = name
def as_string(self, event: QEvent.Type) -> str:
"""Return the string name for this event."""
try:
return self.string_name[event]
except KeyError:
return f"UnknownEvent:{event}"
# Example Usage
event_str = EventTypes().as_string(QEvent.UpdateRequest)
assert event_str == "UpdateRequest"
这是我对我的QWidget子阶级所发生事件的记录。 Just made the lookup table from the docs 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)

PyQt5 并没有给出名字:

PySide2确实:

你可以尝试:
print(QEvent.Type(event.type()).name)
