}
textInputInstance.addEventListener("enter", listenerObject)
Description
Event; notifies listeners that the Enter key has been pressed.
The first usage example uses an
instance. The keyword
component instance. For example, the following code, attached to the instance
sends "_level0.myTextInput" to the Output panel:
on(enter){
trace(this);
}
The second usage example uses a dispatcher/listener event model. A component instance
(
textInputInstance
function, also called a handler, on a listener object (
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
( ) to the listener object method. Each event object has properties that contain
eventObject
information about the event. You can use these properties to write code that handles the event.
Finally, you call the
instance that broadcasts the event to register the listener with the instance. When the instance
dispatches the event, the listener is called.

Example
This example sets a flag in the application that indicates if contents in the TextInput field
have changed:
form.enter = function(eventObj){
// note: eventObj.target refers the component that generated the enter event,
// i.e., the TextInput component.
myFormChanged.visible = true;
// set a change indicator if the user presses Enter;
}
myInput.addEventListener("enter", form);
