title: How to show battery charging status
body: <p>I need to show that my vehicle is being charged. Charging starts when start button is clicked and stops when stop button is clicked on GUI.</p>
  
  <p>i have a GUI for this work where i have to have some kind of image representation to show the status. (Something like our cell phone battery)</p>
  
  <p>I am using SWT.  </p>
  
  <p>Any Suggestion, regarding, how to go about it, will be appreciated.</p>
