클래스 MainWindow에는 이미지와 함께 작동하는 메뉴와 기능이 포함되어 있습니다. 선택한 그림을 보유하는 변수 self.image = QtGui.QImage()이 있습니다. QPixmap을 MainWindow에 사용하면 그림이 표시됩니다. 하지만 Splitter(QtGui.QWidget)과 QGraphicsView이 있는데 이것에 대한 그림을 표시하고 싶습니다. 을 Splitter 클래스 안에 선언하고 이것을 시도했습니다 : Splitter.scene.addPixmap(QtGui.QPixmap.fromImage(image)) MainWindow 클래스 내부에서 작동하지만 작동하지 않습니다. - AttributeError: type object 'Splitter' has no attribute 'scene'. 어떻게해야합니까?PyQt4 - 위젯에서 이미지 표시가 작동하지 않습니다.
