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".

Since:
  1.1

Field Summary
`static int` | `TEXT_FIRST` The first number in the range of ids used for text events.
`static int` | `TEXT_LAST` The last number in the range of ids used for text events.
`static int` | `TEXT_VALUE_CHANGED` This event id indicates that object's text changed.

Constructor Detail

### TextEvent

    public TextEvent(Object source,
                     int id)

  Constructs a `TextEvent` object.

  Note that passing in an invalid `id` results in unspecified behavior.

Parameters:
  `source` - the (`TextComponent`) object that originated the event
  `id` - an integer that identifies the event type

Method Detail

### paramString

    public String paramString()

  Returns a parameter string identifying this text event. This method is useful for event-logging and for debugging.
