The GetLastToggle method returns the last toggle button that was touched by the user. This can be useful when you want to use a single callback function for multiple toggle buttons.

app.GetLastToggle();

function OnStart()
{
  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
 
  btn1 = app.CreateToggle( "Button 1" );
  btn1.SetOnTouch( HandleButton );
  lay.AddChild( btn1 );
 
  btn2 = app.CreateToggle( "Button 2" );
  btn2.SetOnTouch( HandleButton );
  lay.AddChild( btn2 );
 
  app.AddLayout( lay );
}
 
function HandleButton()
{
  var btn = app.GetLastToggle();
  app.ShowPopup( btn.GetText() );
}
