title: Loading spinning wheel animation
body: <p>I'm doing a search and populating a listview with results as they come. On top there's a bar with the text "Search in progress... " I'd like to add a small spinning wheel animation to the bar in the right corner, to show the user that work is being done.</p>
  
  <p>You can see this spinning wheel in the gallery app in the top right corner when thumbnails are being loaded. Also, the same animation is shown in Astro File Manager, when files are being listed in a directory, (again top right corner).</p>
  
  <p>How do I put it there?</p>
