wxPython：第二和第三面板不是 showing/bugging
wxPython: 2nd and 3rd Panels not showing/bugging
我的程序有 3 个面板，我通过隐藏 2 和显示 1 在它们之间切换。但是，只有第 1 个面板。 1 似乎有效，因为当我切换到第 2 或第 3 时，除了左上角的一个小白框外，框架是灰色的。是什么原因造成的？任何帮助，将不胜感激。 （下面提供的代码）

据我所知，BoxSizer 将面板放在单独的单元格中，并使用面板大小来计算单元格大小。尝试在开始时对所有面板使用 Show()，您会同时看到所有面板 - 一个在另一个下面。
当您隐藏第一个面板时，BoxSizer 不会重新计算单元格大小，它仍会显示第一个单元格，但带有隐藏面板，因此您看不到其他面板。您可以使用 self.Layout() 强制所有 window 重新计算大小。
