42         
43         self.setGeometry(300,300,280,150)
44         self.setWindowTitle('Click or Move')
45         self.show()
46     
47     def dragEnterEvent(self, e):
48         e.accept()
49         
50     def dropEvent(self, e):
51         position = e.pos()
52         self.button.move(position)
53         
54         e.setDropAction(Qt.MoveAction)
55         e.accept()
56 
57 if __name__ == '__main__':
58     app = QApplication(sys.argv)
59     ex = New_test()
60     sys.exit(app.exec_())
61         
62

在Button上右键拖动时，按钮会跟随鼠标移动，如果是在Button左键时，会在控制台上打印出 "press"
