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 everyTextListener
object which registered to receive such events using the component'saddTextListener
method.The object that implements the
TextListener
interface gets thisTextEvent
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 particularTextEvent
instance is not in the range fromTEXT_FIRST
toTEXT_LAST
.- Since:
