title: tkinter Checkbox set value if checked
body: <p>I am using tkinter as a front end for Cisco IOS automation, but the problem i face is i need to have check-boxes available, if checked the text associated to it should be passed to the Cisco IOS.
  I tried to look into tkinter documentation but no luck.</p>
  
  <pre><code>Var = Tkinter.StringVar()
  cv1 = Tkinter.Checkbutton(SecondFrame,text='show cdp neighbor', variable=Var)
  cv1.grid(row=3, column=5, sticky='S', padx=5, pady=2)
  </code></pre>
