代码实例1。

import wx
  
  
class Example(wx.Frame):
  
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
  
        self.InitUI()
  
    def InitUI(self):
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
  
        self.menubar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.item = wx.MenuItem(self.fileMenu, 1, '&Check', helpString ="Check Help", kind = wx.ITEM_RADIO)
        self.item.SetBitmap(wx.Bitmap('right.png'))
        self.fileMenu.Append(self.item)
        self.menubar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menubar)
        # kind of menu item
        kind = self.item.GetKind()
        # print kind of menuitem
        print(kind)
        self.SetSize((350, 250))
        self.SetTitle('Icons and shortcuts')
        self.Centre()
  
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()

输出。

2 //2 corresponds to wx.ITEM_RADIO

        self.menubar.Append(self.fileMenu, '&File')
        self.SetMenuBar(self.menubar)
        # kind of menu item
        kind = self.item.GetKind()
        # print kind of menuitem
        print(kind)
        self.SetSize((350, 250))
        self.SetTitle('Icons and shortcuts')
        self.Centre()
  
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()

0 //0 corresponds to wx.ITEM_RADIO
