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.
TextComponent, TextListener, Serialized Formpublic static final int TEXT_FIRST
The first number in the range of ids used for text events.
public static final int TEXT_LAST
The last number in the range of ids used for text events.
public static final int TEXT_VALUE_CHANGED
This event id indicates that object's text changed.
public TextEvent(Object source,
int id) Constructs a TextEvent object.
This method throws an IllegalArgumentException if source is null.
source - The (TextComponent) object that originated the eventid - An integer that identifies the event type. For information on allowable values, see the class description for TextEvent
IllegalArgumentException - if source is nullEventObject.getSource(), AWTEvent.getID()
public String paramString()
Returns a parameter string identifying this text event. This method is useful for event-logging and for debugging.
