Question

我用QMainWindow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

我在每个eventtype QEvent \ QPaintEvent \ QHoverEvent \ etc中遇到无穷无尽的错误：

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

我怎样摆脱它？

提前，

Answer 1

eventFilter()不是类方法，因此您还需要传递self：

return QObject.eventFilter(self, obj, event)

PyQt的。类型错误
