    ui.setupUi(window) 
    window.show() 
    sys.exit(app.exec_())

我想actionExit - > programExit（），但是这个代码不工作错误：类型错误：参数不匹配任何重载呼叫请解决这个问题的PyQt的QAction连接到退出弹出

考虑[如何创建一个最小的，完整的，并且可验证的示例]（https://stackoverflow.com/help/mcve），代码中引发了以下错误：'导入错误：没有模块名为iconresource'。 – Matho

即外部图标py文件。除了那个和重试 –

好，继续出现错误信息：

... 
QMessageBox.question(QWidget, QString, QString, QMessageBox.StandardButtons 
buttons=QMessageBox.Ok, QMessageBox.StandardButton defaultButton=QMessageBox.NoButton): 
argument 1 has unexpected type 'Ui_MainWindow' 
...

你self不是QWidget而是Ui_MainWindow。将self更改为self.centralwidget，它应该可以工作。

def programExit(self): 
    quit_msg = "Are you sure you want to exit the program?" 
    reply = QtGui.QMessageBox.question(self.centralwidget, 'Message', quit_msg, QtGui.QMessageBox.Yes, QtGui.QMessageBox.No) 
    if reply == QtGui.QMessageBox.Yes: 
     sys.exit() 
    else: 
     pass
