PyQt。类型错误
我在 QMainWindow 上设置过滤器：
keyPressFilter = keypressfilter.KeyPressFilter(self)
self.installEventFilter(keyPressFilter)
KeyPressFilter 本身：
class KeyPressFilter(QObject):
def __init__(self, parent=None):
super(KeyPressFilter, self).__init__(parent)
def eventFilter(self, obj, event):
if event.type() == QEvent.KeyPress:
print "key press %d" % event.key()
return True
else:
return QObject.eventFilter(obj, event) <- line NN
并且每个事件类型 QEvent\QPaintEvent\QHoverEvent\etc 都会出现无尽的错误：
line NN, in eventFilter:
TypeError: QObject.eventFilter(QObject, QEvent): argument 2 has unexpected type 'QPaintEvent'
我怎样才能摆脱它？
提前致谢，

I set filter on my QMainWindow with this:
keyPressFilter = keypressfilter.KeyPressFilter(self)
self.installEventFilter(keyPressFilter)
KeyPressFilter itself:
class KeyPressFilter(QObject):
def __init__(self, parent=None):
super(KeyPressFilter, self).__init__(parent)
def eventFilter(self, obj, event):
if event.type() == QEvent.KeyPress:
print "key press %d" % event.key()
return True
else:
return QObject.eventFilter(obj, event) <- line NN
and i getting endless errors with every eventtype QEvent\QPaintEvent\QHoverEvent\etc:
line NN, in eventFilter:
TypeError: QObject.eventFilter(QObject, QEvent): argument 2 has unexpected type 'QPaintEvent'
How can i get rid of it?
Thx in advance,
Serge

eventFilter()不是类方法，因此您还需要传递self：eventFilter()is not a class method, so you need to passselfas well:
