====== GetType ======
All visible controls and even layouts have a GetType() method which returns a string indicating the type of the control.
===== Sample code =====
This sample uses GetType to decide whether an OnTouch handler has been called by a Text or a TextEdit and only shows a pop-up once, either way.
<code JavaScript GetType.js>
function onTouch(ev)
{
    var type=this.GetType();
    if(type=="Text" && ev.action=="Up")
       app.ShowPopup(this.GetText());
    else if(type=="TextEdit")
      app.ShowPopup(this.GetText());
}
