wxpython类中的定时器wx.Timer方法不能运行

Question

wxpython类中的定时器wx.Timer方法不能运行，不知缺少了什么命令代码，请求指教，谢谢！

import wx
class MyFrame(wx.Frame):
    eve = 1
    
    def __init__(self):
        super().__init__(parent=None,title="vbox",size=(500,400),pos=(100,100))   #继承wx.Frame类
        self.Center()
        self.panel = wx.Panel(parent=self)   #面板
        vbox = wx.BoxSizer(wx.VERTICAL)
        self.bmps=[wx.Bitmap(f"{i}.png",wx.BITMAP_TYPE_PNG) for i in range(1,6)]
        self.image=wx.StaticBitmap(self.panel,-1,self.bmps[0])
        self.timer=wx.Timer(self.panel)
        b1=wx.Button(self.panel,id=1,label='自动播放')
        self.Bind(wx.EVT_BUTTON,self.on_click,id=1,id2=5)
        self.Bind(wx.EVT_TIMER,self.keep_play,self.timer)
        vbox.Add(b1,1,wx.CENTER)
        vbox.Add(self.image,5,wx.CENTER)
        self.panel.SetSizer(vbox)

    def on_click(self,event):
        event_id = event.GetId()
        if event_id==1:
            self.timer.Start(100)

    def keep_play(self,event):
        if self.eve<5:
            self.image.SetBitmap(self.bmps[self.eve])
        else:
            self.eve=0
            self.image.SetBitmap(self.bmps[self.eve])
        self.eve=self.eve+1
        
class App(wx.App):
    def OnInit(self):    #进入
        frame = MyFrame()
        frame.Show()
        return True
    def OnExit(self):   #退出
        print("tuichu")
        return 0

if __name__ == '__main__':
    app=App()
    app.MainLoop()
