我的程序有3个面板，我通过隐藏2并显示1来切换。但是，只有Panel no。 1似乎工作，因为当我切换到第2或第3时，框架是灰色的，左上角有一个小白框。是什么造成的？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()，同时看到所有面板 - 一个在另一个面板之下。
当您隐藏第一个面板时，BoxSizer不会重新调整单元格大小，它仍然会显示第一个单元格，但隐藏面板，因此您不会看到其他面板。您可以使用self.Layout()强制所有窗口重新计算大小。
def onPanelSwap(self, event):
...
self.Layout()
event.Skip()
顺便说一句：您可以使用wx.Notebook创建的Example来展示多个面板 - {{3}}
