public Class TextEvent

extends AWTEvent
Class Inheritance
Imports
java.awt.AWTEvent, java.io.Serial
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.
