Question

我试图理解how sizer and sizes work但很明显，我错过了一些至关重要的东西。这就是我得到的：

显然，内部面板（sizer）不适合窗户。我想要的是这个：

是由手动重新设置的。

我该如何实现？

请注意，真实代码有更多不同的wx.StaticBox，因此对我所做错误的一般解释会比仅仅修复更受欢迎。

以下是玩具示例代码：

在这种情况下最简单的方法是给框架一个sizer，添加主面板，然后调用框架的Fit方法。例如，您可以将self.SetSize中的GUIControl.__init__来电替换为：

    frameSizer = wx.BoxSizer()
    frameSizer.Add(panel, 1, wx.EXPAND)
    self.SetSizer(frameSizer)
    self.Fit()

设置最小窗口大小，以便所有大小适合
