public class TextEvent extends AWTEvent
A semantic event which indicates that an object's text changed. This high-level event is generated by an object (such as a TextComponent) when its text changes. The event is passed to every TextListener
object which registered to receive such events using the component's addTextListener
method.
The object that implements the TextListener
interface gets this TextEvent
when the event occurs. The listener is spared the details of processing individual mouse movements and key strokes Instead, it can process a "meaningful" (semantic) event like "text changed".
An unspecified behavior will be caused if the id
parameter of any particular TextEvent
instance is not in the range from TEXT_FIRST
to TEXT_LAST
.
