addBlurHandler(handler)

Add a handler for blur events (losing keyboard focus).

Note that you can have multiple handlers for the same event on the same widget. They will be called in the order that they were added to the widget, although ServerHandlers may appear to happen simultaneously.

The handler passes back some information to the server about what happened. This information can be accessed as follows:

 
function doGet() {
   var app = UiApp.createApplication();
   var button = app.createButton("a button");
   var handler = app.createServerHandler("handlerFunction");
   button.addBlurHandler(handler);
   app.add(button);
   return app;
 }

 function handlerFunction(eventInfo) {
   var parameter = eventInfo.parameter;
   // the type of event, in this case "blur".
   var eventType = parameter.eventType;
   // the id of the widget that fired this event.
   var source = parameter.source;
 }
 

Parameters

Return

SimpleRadioButton — the SimpleRadioButton itself, useful for chaining.
