我正在尝试使用Tkinter在Python中构建GUI。我的想法是在根框架内构建几个框架。我可以出现2帧，但第三帧覆盖第二帧。我已经尝试将pack（）和grid（）作为根帧中的布局管理器。
我希望有一个“顶部的东西”框架和一个“底部的东西”框架，其间有1个Cat1框架和1到8个Cat2框架。当应用程序发现它控制的Cat2小部件数量时，GUI需要能够动态重建。
（另一个小问题。由于我介绍了Cat2Frame类并将tkFont变量移动到全局范围，我的12点字体仍然只有9分。）
这是我的清理过的代码段。 （尚未进入底部框架。）

答案 0 :(得分：3)
您的代码的简短答案是您为两个Cat2Frame对象指定了相同的名称。要么给它们唯一的名称，要么不要使用框架的name属性。
另外，我建议你重新考虑一下你的编程风格吗？你编写代码的方式很难阅读。我发现将布局与窗口小部件创建分开有助于实现，并且可能更容易找到这个错误（因为能够一目了然地看到所有布局以确定它是正确的）。
这是一个快速入侵，展示如何重构代码以使其更具可读性。我不是说这是重构代码的最好方法，我只是把它作为思考的食物。
我假设您希望所有行都布置在单个网格中，因此您的每个“帧”（Cat1Frame，Cat2Frame）都不是实际帧，因为很难将单元格对齐小部件。如果不是这种情况（即：如果每个“Frame”真的是一个独立的小部件），代码可以变得更简单。
我没有花时间创建顶行，也没有花时间让所有行和列完全正确调整大小。我还给每个文本小部件一个背景，这样你就可以看到它们是如何布局的。我发现当您可以看到小部件的边界时，解决布局问题会更加简单。
