我是一名Python初学者，试图编写一个应用来测试IDS，防火墙等重要安全软件包的存在.GUI上有4个类别按钮。我只希望显示与该类别相关的文本。例如：如果按下“恶意代码保护”，则只需显示“防火墙”，“入侵检测系统”和“Rootkit扫描程序”，即必须隐藏所有剩余文本。我想出了这个样板代码。我看到文本有时重叠或按钮不隐藏。如何简化此代码并确保分类显示完美运行。

答案 0 :(得分：1)
您的代码无效的原因：
有很多运行时错误，例如“self.bt7”的错误和构造之前使用的btn对象。您可以在控制台中检查这些错误。
出现这些错误，一些代码用于隐藏未调用的按钮。
其他一些建议：
您使用了数百个“_”的StaticText来绘制线条。它让你的应用程序变得非常慢。实际上你可以用“wx.DrawLine”
当您按类别显示信息时，您只需要3个StaticText用于描述，2个按钮用于“安装”。您不需要定义这么多变量（例如btn10，btn11）
我根据您的代码做了一些更改，您可以尝试一下：
