如何在python中将wxpython Gauge小部件与线程同步？

import wx
import threading
import time

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="Gauge示例")
        
        panel = wx.Panel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        
        self.gauge = wx.Gauge(panel, range=100)
        sizer.Add(self.gauge, 0, wx.EXPAND|wx.ALL, 10)
        
        start_button = wx.Button(panel, label="开始")
        start_button.Bind(wx.EVT_BUTTON, self.start_thread)
        sizer.Add(start_button, 0, wx.ALIGN_CENTER|wx.ALL, 10)
        
        panel.SetSizer(sizer)
        sizer.Fit(self)
    
    def start_thread(self, event):
        thread = threading.Thread(target=self.update_gauge)
        thread.start()
    
    def update_gauge(self):
        for i in range(101):
            time.sleep(0.1)  # 模拟耗时操作
            wx.CallAfter(self.gauge.SetValue, i)  # 使用wx.CallAfter更新Gauge小部件的值

app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
