【采用Qmessage自定义生成弹窗】

        msgBox = QMessageBox()
        msgBox.setText("The document has been modified.")
        msgBox.setInformativeText("Do you want to save your changes?")
        msgBox.setStandardButtons(QMessageBox.Save | QMessageBox.Discard | QMessageBox.Cancel)
        msgBox.setDefaultButton(QMessageBox.Save)
        ret = msgBox.exec_()
        
        if ret == QMessageBox.Save:
            print('你选择了Save')
        if ret == QMessageBox.Discard:
            print('你选择了Discard')
        if ret == QMessageBox.Cancel:
            print('你选择了Cancel')

弹窗格式：

 

注意：默认的button 是Save

 

 【使用静态方法调用】

【自定义按钮-复杂版】

        ret = QMessageBox.warning(main, "My Application",
                                  "The document has been modified.\n" + \
                                  "Do you want to save your changes?",
                                  QMessageBox.Save | QMessageBox.Discard
                                  | QMessageBox.Cancel,
                                  QMessageBox.Save)
        if ret == QMessageBox.Save:
            print('你选择了Save')
        if ret == QMessageBox.Discard:
            print('你选择了Discard')
        if ret == QMessageBox.Cancel:
            print('你选择了Cancel')
