构建一些随机示例我砍掉了这个美丽的窗口。我很遗憾使用QDialog示例而不是QMainWindow。我喜欢QMainWindow及其功能的外观。现在我无法进行转换（纯粹的无知）。代码变得相当长，所以我想我会从QMainWindow调用这段代码，但是当我这样做时，会有一些关闭所有python的灾难。我可以将其转换为QMainWindow还是从QMainWindow打电话给我？将我的Qdialog更改为QMainWindow

小错误，但你的代码为我工作（Python的3.3） – ngulam
的代码工作正常，但我希望改变这个QDialog程序与QMainWindow一起使用。 – user2177088
