我有一个对话框，里面有一个 ScrolledWindow，并且该 ScrolledWindow 中有一个动态数量的控件。
该对话框目前还不够大。我可以手动设置宽度和高度，但我不知道它们会是什么，所以我希望 sizer 自动设置大小，我相信这是 wxWidgets 希望你这样做的方式。
ScrolledWindow 有一个 sizer，它似乎可以正确计算尺寸要求。
我已将 ScrolledWindow 添加到 Dialog 的 sizer 中，但 Dialog 的 sizer 似乎没有考虑 ScrolledWindow 的大小来计算它的大小，因此它比 ScrolledWindow 的 sizer 认为的要小。
下面的日志演示了我的问题。为什么 scrolling_window 和 scrolling_window_sizer 认为它们的大小是 (267, 480)，但 dialog_sizer 认为它可以逃脱 (210, 63) ？为什么？

请注意，这是使用 wxPython 的 python，但我希望这是我使用 wxWidgets 而不是 wxPython 的一般问题。这是一大堆代码，但希望它足够简单易读。上面打印日志的行已用#! 标记。
This line: # 这行有问题。没有它，我认为sizer不会自动调整窗口。有了它，窗户就很小了。大小 = dialog_sizer.Fit(self) self.Layout()
我添加自己是为了让 sizer 重新调整对话框的大小。我不确定是否应该在布局前或布局后进行 Fit，但这似乎并不重要，因为如上面的日志所示，sizer 似乎没有考虑按钮，但没有考虑滚动窗户。

代码本身大部分是由 wxFormBuilder 生成的，我自己进行了修改以使其具有动态性。我假设 wxFormBuilder 编写的代码是正确的。但它就在这里，以防你认为它不正确并且以错误的顺序做某事，或者我修改得很糟糕；）
