我的wxPython代码存在一些大小问题。我有一个StaticText帮助消息，可以显示或隐藏，并且消息需要根据用户模式进行更改。wxPython StaticText在文本更改时不会调整大小
默认情况下会发生的情况是，包含StaticText的BoxSizer在第一次显示StaticText时会正确地假设它的大小，但在StaticText内容更改时不会重新调整大小。
我最初的代码看起来像这样（为背景，完整的代码是在我的帖子的末尾）：
self.msg_text = wx.StaticText(self.panel, label=self.default_msg_text,
style=wx.TE_CENTER | wx.EXPAND,
name='help msg text’)
self.help_msg_boxsizer.Add(self.msg_text, flag=wx.EXPAND)
self.help_msg_boxsizer.ShowItems(False)
然后我尝试手动设置大小：
self.msg_text_size = (500, 100)
self.msg_text = wx.StaticText(self.panel, label=self.default_msg_text,
style=wx.TE_CENTER | wx.EXPAND,
name='help msg text',
size=self.msg_text_size)
self.help_msg_boxsizer.Add(self.msg_text, flag=wx.EXPAND)
self.help_msg_boxsizer.ShowItems(False)
，然后使用：
self.msg_text.SetSize(new_size)
# or
self.help_msg_boxsizer.GetStaticBox.SetSize(new_size)
但无论这些线似乎工作。相反，无论如何，（500,100）的初始尺寸似乎仍然可以使用。
我想设置大小提示可能有帮助，但它似乎没有任何效果：
self.help_msg_boxsizer.SetSizeHints()
最后，是否存在wx.EXPAND似乎没有什么区别。
总结：我想要做的是适当地重新大小self.msg_text到所需的最小尺寸时显示。我怎样才能做到这一点？
以下是完整的代码运行我的例子：
