wxPython在运行时创建一个带有子列表的巨大的可点击列表？

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="Clickable List", size=(400, 300))
        
        # 创建TreeCtrl控件
        self.tree = wx.TreeCtrl(self)
        
        # 添加根节点
        root = self.tree.AddRoot("Root")
        
        # 添加子节点
        for i in range(1000):
            child = self.tree.AppendItem(root, f"Item {i}")
            
            # 添加子列表
            for j in range(10):
                sub_child = self.tree.AppendItem(child, f"Sub Item {j}")
        
        # 绑定事件处理函数
        self.tree.Bind(wx.EVT_TREE_ITEM_ACTIVATED, self.on_item_activated)
        
    def on_item_activated(self, event):
        item = event.GetItem()
        text = self.tree.GetItemText(item)
        print(f"Clicked: {text}")
        
app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
