Python 链接按钮以运行.py文件

我想做的是通过单击main.py上的按钮打开grid.py。最好保持相同的结构（ui文件以及主python文件和网格python文件）。谢谢,

因此，我创建了一个简单的UI界面，其中只包含一个带有Qt设计器的按钮（test open.UI）：

最后，这是我用WxPython创建的一个网格，我想通过点击按钮（Grid.py）打开它

---

您混淆了这些概念，程序不是一组文件，而是基于类创建的对象之间的交互。因此，在实现任何内容之前，我将假设文件具有以下结构：

├── grid.py
├── main.py
└── test-open.ui

另一方面，在应用程序类构造函数中，您正在显示窗口，而这不是您想要的，最初必须关闭窗口，因此我将删除该行。说到这里，您必须在main中导入网格模块才能创建应用程序小部件对象

谢谢@eyllanesc，效果很好。你说的是哪一行显示窗口？最后一个问题，如果我的main.py上有两个按钮，我如何区分单击了哪一个？@CreekBarbara 1）显示窗口的行是.ui中的以下

dlg.button.clicked.connect（w.show）

2）每个按钮都有一个名称：

，因此，如果你有另一个按钮，它将有另一个名称。我在你发布答案的同时计算出了这个名称：）。对于第一个问题，我问的是关于你从我的代码中删除的那一行，我不能把我的手指放在上面。非常感谢。again@CreekBarbara这行代码显示小部件self.Show（）
