WxPython - 添加新内容时如何调整WxFrame大小？
基本上就是这个意思。我在一个 Wx.Frame 窗口里有一些按钮，这些按钮是动态创建的。我希望当我添加新按钮时，父窗口的高度也能自动增加。现在的做法是根据按钮的总数乘以每个按钮的高度来计算总高度，但我不知道怎么让窗口在添加新按钮时自动调整大小。
另外，我现在更新按钮的方法会导致窗口闪烁，我想知道有没有人能给我一些解决这个问题的建议。

不要在你的方法前面加两个下划线，除非你知道自己在做什么。虽然这和你的问题没有直接关系，但这样做会导致一些你之后无法理解的错误。
可以看看这个 stackoverflow 上的问题，以及 Python 文档，了解一下为什么要这样做。

据我所知，没有办法自动调整框架的大小，但你可以用 SetSize() 手动重设框架的大小。
例如：
w, h = self.GetClientSize()
self.SetSize((w, h + height_of_your_new_button))
不过，如果想要达到理想的效果而又不想麻烦的话，你需要使用布局管理器（sizers）。我觉得没有必要使用绝对定位。还建议使用面板，这样可以在不同的控件之间方便地切换，并且在不同平台上布局的一致性也更好。
