Description
Event; broadcast to all registered listeners when the mouse is clicked (pressed and released)
over the radio button or if the radio button is selected by means of the arrow keys. The event
is also broadcast if the Spacebar or arrow keys are pressed when a radio button group has
focus, but none of the radio buttons in the group are selected.
The first usage example uses a dispatcher/listener event model. A component instance
(
radioButtonInstance) dispatches an event (in this case, click) and the event is handled by
a function, also called a handler, on a listener object (
listenerObject) that you create. You
define a method with the same name as the event on the listener object; the method is called
when the event is triggered. When the event is triggered, it automatically passes an event
object (
eventObject) to the listener object method. The event object has properties that
contain information about the event. You can use these properties to write code that handles
the event. Finally, you call the
EventDispatcher.addEventListener() method on the
component instance that broadcasts the event to register the listener with the instance. When
the instance dispatches the event, the listener is called.
