python中wx将图标显示在右下角的脚本代码

代码如下:
import wx
import images
class DemoTaskBarIcon(wx.TaskBarIcon):
    TBMENU_RESTORE = wx.NewId()
    TBMENU_CLOSE   = wx.NewId()
    TBMENU_CHANGE  = wx.NewId()

        self.frame = frame

        # Set the image
        icon = self.MakeIcon(images.getWXPdemoImage())
        self.SetIcon(icon, "wxPython Demo")
        self.imgidx = 1

        # bind some events
        self.Bind(wx.EVT_TASKBAR_LEFT_DCLICK, self.OnTaskBarActivate)
        self.Bind(wx.EVT_MENU, self.OnTaskBarActivate, id=self.TBMENU_RESTORE)
        self.Bind(wx.EVT_MENU, self.OnTaskBarClose, id=self.TBMENU_CLOSE)
        self.Bind(wx.EVT_MENU, self.OnTaskBarChange, id=self.TBMENU_CHANGE)

    def CreatePopupMenu(self):
        """

        the menu for the default EVT_RIGHT_DOWN event.  Just create

        """
        menu = wx.Menu()
        menu.Append(self.TBMENU_RESTORE, "Restore wxPython Demo")
        menu.Append(self.TBMENU_CLOSE,   "Close wxPython Demo")
        menu.AppendSeparator()
        menu.Append(self.TBMENU_CHANGE, "Change the TB Icon")
        menu.Append(self.TBMENU_REMOVE, "Remove the TB Icon")
        return menu

    def MakeIcon(self, img):
        """
        The various platforms have different requirements for the
        icon size...
