PyQt。类型错误

Question

我设置过滤器对我的QMainWindow本：

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 

，我让每事件类型的QEvent \ QPaintEvent \ QHoverEvent \等无尽的错误：

line NN, in eventFilter: 
TypeError: QObject.eventFilter(QObject, QEvent): argument 2 has unexpected type 'QPaintEvent' 

我该如何摆脱它？

Thx提前，

eventFilter()是不是一个类的方法，所以你需要通过self还有：

return QObject.eventFilter(self, obj, event)
