Question

我正在使用TKinter在python上开发此Tennis GUI程序。我在下面的代码中遇到的当前错误是'self.title_frame'甚至没有出现在GUI的row0处。它完全消失了。是什么原因导致此问题？

此外，没有实际的错误消息。仅仅是顶部框架（self.title_frame）没有显示在第0行上的问题。实际上，不仅不显示它，而且位于第0行的标签（self.title_label）也会显示在第0行，而没有显示在它下面的框架。

Answer 1

框架正在显示，因为标签在框架内，因此，如果您看到了，则表明框架已包装好。我认为您遇到的问题是框架不符合您为其指定的宽度和高度。要解决此问题，请关闭网格传播。即。

self.root.grid_propagate(False)

这意味着当将小部件添加到框架时，框架不会调整大小以匹配该小部件。
