The GetLastImage method returns the last image control that was touched by the user. This can be useful when you want to use a single callback function for multiple images.

 app.GetLastImage();

function OnStart()
{
  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
 
  img1 = app.CreateImage( "/Sys/Img/Hello.png" );
  img1.SetOnTouch( HandleImage );
  lay.AddChild( img1 );
 
  img2 = app.CreateImage( "/Sys/Img/Droid1.png" );
  img2.SetOnTouch( HandleImage );
  lay.AddChild( img2 );
 
  app.AddLayout( lay );
}
 
function HandleImage()
{
  var img = app.GetLastImage();
  img.Rotate( 180 );
}
