        super(Example, self).__init__(*args, **kwargs) 
  
        self.InitUI() 
  
    def InitUI(self):
  
        self.count = 5
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH) 
        self.toolbar = self.CreateToolBar() 
        tundo = self.toolbar.AddTool(wx.ID_UNDO, '', wx.Bitmap('right.png')) 
        tredo = self.toolbar.AddTool(wx.ID_REDO, '', wx.Bitmap('wrong.png')) 
  
        self.toolbar.Realize() 
        self.Bind(wx.EVT_TOOL, self.OnUndo, tundo) 
        self.Bind(wx.EVT_TOOL, self.OnRedo, tredo) 
  
        print(self.ToolBar.GetToolsCount()) 
        self.SetSize((350, 250)) 
        self.SetTitle('Undo redo') 
        self.Centre() 
  
    def OnUndo(self, e):
        if self.count > 1 and self.count <= 5:
            self.count = self.count - 1
  
        if self.count == 1:
            self.toolbar.EnableTool(wx.ID_UNDO, False) 
  
        if self.count == 4:
            self.toolbar.EnableTool(wx.ID_REDO, True) 
  
    def OnRedo(self, e):
        if self.count < 5 and self.count >= 1:
            self.count = self.count + 1
  
        if self.count == 5:
            self.toolbar.EnableTool(wx.ID_REDO, False) 
  
        if self.count == 2:
            self.toolbar.EnableTool(wx.ID_UNDO, True) 
  
  
    def OnQuit(self, e):
        self.Close() 
  
  
def main():
  
    app = wx.App() 
    ex = Example(None) 
    ex.Show() 
    app.MainLoop()
