toolid	int	An integer by which the tool may be identified in subsequent operations.
label	string	The string to be displayed with the tool.
bitmap1	wx.bitmap	The primary tool bitmap.
bmpDisabled	wx.bitmap	The bitmap used when the tool is disabled.
shortHelp	string	This string is used for the tools tooltip.
longHelp	string	detailed string associated with tool.
clientData	PyUserData	An optional pointer to client data which can be retrieved later using GetToolClientData.

Return Type : wx.ToolBarToolBase

代码示例：

import wx
  
  
class Example(wx.Frame):
    global count
    count = 0;
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
  
        self.InitUI()
  
    def InitUI(self):
        pnl = wx.Panel(self)
        self.toolbar = self.CreateToolBar()
  
        # create check toolusing AddCheckTool() function
        rtool = self.toolbar.AddCheckTool(12, 'CheckTool', 
                   bitmap1 = wx.Bitmap('/Desktop/wxPython/right.png'), 
                   bmpDisabled = wx.Bitmap('/Desktop/wxPython/wrong.png'))
  
        self.toolbar.Realize()
  
        self.SetSize((350, 250))
        self.SetTitle('Simple toolbar')
        self.Centre()
          
  
  
def main():
  
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
