pyqt4怎么给菜单里的选项添加事件啊?

Question

RT怎么添加事件啊？

Answer 1

以常见的Help菜单下的About项目为例，通过self.actionAbout.triggered.connect(self.onAbout)方法，绑定onAbout函数为响应事件函数。

// 添加菜单动作，绑定事件
self.actionAbout = QtGui.QAction(MainWindow)
self.actionAbout.setText(_fromUtf8("About"))
self.actionAbout.setIconText(_fromUtf8("About"))
self.actionAbout.setToolTip(_fromUtf8("About"))
self.actionAbout.setStatusTip(_fromUtf8("About"))
self.actionAbout.setObjectName(_fromUtf8("actionAbout"))
self.menuHelp.addAction(self.actionAbout)
self.actionAbout.triggered.connect(self.onAbout)

// 响应事件
def onAbout(self):
    QMessageBox.about(self, "About", "This is a about")
