如何从TextCtrl派生wxPython自定义控件

import wx

class MyTextCtrl(wx.TextCtrl):
    def __init__(self, parent, id=wx.ID_ANY, value="", pos=wx.DefaultPosition, size=wx.DefaultSize, style=0):
        super(MyTextCtrl, self).__init__(parent, id, value, pos, size, style)
        self.Bind(wx.EVT_TEXT, self.OnTextChange)

    def OnTextChange(self, event):
        print("Text changed to:", self.GetValue())

# 创建应用程序对象
app = wx.App(False)

# 创建窗口
frame = wx.Frame(None, wx.ID_ANY, "Custom TextCtrl Example")

# 创建自定义TextCtrl实例
my_text_ctrl = MyTextCtrl(frame, wx.ID_ANY, style=wx.TE_PROCESS_ENTER)

# 设置布局
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(my_text_ctrl, 0, wx.ALL, 5)
frame.SetSizer(sizer)

# 显示窗口
frame.Show()

# 启动主循环
app.MainLoop()
