求助wxpython创建绑定单击事件一级菜单的方法，wxpython绑定,如题,尝试在一级菜单中绑

如题,尝试在一级菜单中绑定单机事件,但无论如何尝试都以失败告终.

发现在菜单追加的二级菜单是可以正常绑定事件的,但是一级菜单wx.Menu即使是绑定wx.EVTMENUOPEN事件也会导致无法显示,求解决!

编译环境:Eclipse+Pydev+Python2.7

我的代码如下,虽然编译通过了,但是无法正常显示:

#-*- coding: utf-8 -*-import wxclass App(wx.App):    def OnInit(self):        self.frame = rpFrame(parent=None, id=-1)        self.frame.Show()        self.SetTopWindow(self.frame)        return Trueclass rFrame(wx.Frame):    def __init__(self, parent=None, id=-1):        wx.Frame.__init__(self, parent, id,'标题')#状态栏        statusBar = self.CreateStatusBar() #菜单栏        menuBar = wx.MenuBar()        self.SetMenuBar(menuBar)#菜单        menu1 = wx.Menu()        menuBar.Append(menu1, "文件")        menu2 = wx.Menu()        menuBar.Append(menu2, "退出")#绑定事件        self.Bind(wx.EVT_MENU, self.OnCloseMe, menu1)    def OnCloseMe(self, event):        self.Close(True)if __name__ == '__main__':    app = App()    app.MainLoop()
