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.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()
  
  
if __name__ == '__main__':
