PYQT5(十一)实现右键菜单

窗体绑定右键事件

        self.window.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
        self.window.customContextMenuRequested.connect(self.rightMenuShow)

设置右键菜单事件，和后续的动作

def rightMenuShow(self):
        try:
            self.contextMenu = QMenu()
            self.actionA = self.contextMenu.addAction(u'动作a')
            self.contextMenu.popup(QCursor.pos())  # 2菜单显示的位置
            self.actionA.triggered.connect(self.actionHandler)
            self.contextMenu.show()
        except Exception as e:
            print(e)
    def actionHandler(self):
        print('action')
