Wxpython:未显示多个面板

我正在制作一个预算程序，显示所有用户的费用。我希望这样，当用户单击ListUI时，它会显示关于该类别的所有数据。我可以让程序在两个类别面板之间切换，但是我无法让摘要页面正确显示。它只是一片空白，没有任何信息

（在列表界面旁边放置面板的额外积分，这是我想学习的东西，但我还没有学到。）

几件事：显示面板时不要创建面板。在之前创建并隐藏它。当你需要的时候，用信息填写并显示出来。我强烈建议您使用WxGlade使用wxPython构建图形部件。遗憾的是，您发布的代码片段只为我们提供了一包代码扳手。我不知道这些事情是如何联系在一起的，我怀疑你会得到一个有用的答案。要么发布完整代码，要么
