WXPython，无法为包含很长单词的TextCtrl设置自动换行

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        super(MyFrame, self).__init__(parent, title=title, size=(400, 300))
        
        panel = wx.Panel(self)
        text_ctrl = wx.TextCtrl(panel, style=wx.TE_WORDWRAP)
        text_ctrl.SetMinSize((380, 200))
        
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(text_ctrl, 1, wx.EXPAND | wx.ALL, 10)
        panel.SetSizer(sizer)

if __name__ == '__main__':
    app = wx.App(False)
    frame = MyFrame(None, 'WXPython TextCtrl Auto Wrap Example')
    frame.Show()
    app.MainLoop()
