Description
Event; broadcast to all registered listeners when the user presses the Enter key in the text box.
This event is a TextInput event that is broadcast only from editable combo boxes. For more
information, see
TextInput.enter.
Using a dispatcher/listener event model, a component instance (
comboBoxInstance)
dispatches an event (in this case,
enter) 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. Each 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
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.
