补充一下，就是怎么才能看见我的Windows窗体？

[thy38]

在#End后面贴上

def main(args):  
    app = QApplication(args)  
    win = Ui_MainWindow()  
    win.show()  
    app.exec_loop()  
  
if __name__ == "__main__":  
    main(sys.argv)

谢谢了，但是我还是弄不出来啊。。我是才学的。看看错误再给我改改行吗？？

不会qt，不过按lz的设计应该先得到一个窗口当参数后呼叫setupUi，而2楼给的方式嘛，你的类要改写得要继承某个qt类，并定义__init__函数，不然是跑不起来的。觉得初学直接用rad工具算了，然后学习自动生成的代码...

[Quote=引用 5 楼 thy38 的回复:]
对啊，我当时就想问的，最后忘了，你的代码不全吧？连构造函数都没有？你是PyQT的新手还是Python的新手？

我是python新手。不过我想整点好看的界面的应用程序。没办法了。。只有发帖子求救了。。

[dichaofeng]

顺便说一下 class Ui_MainWindow(object): 中（object）是什么啊？？？
