wxPython:手动调用事件

import wx

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(MyFrame, self).__init__(*args, **kwargs)

    def on_start(self):
        print("程序已开始")

    def on_stop(self):
        print("程序已停止")

app = wx.App(False)
frame = MyFrame(None, wx.ID_ANY, "")
frame.Show()
app.MainLoop()
