## java.awt.event
Class TextEvent

    java.lang.Object
      java.util.EventObject
          java.awt.AWTEvent
              java.awt.event.TextEvent

All Implemented Interfaces:
  Serializable

    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.

### TEXT_FIRST

    public static final int TEXT_FIRST

  The first number in the range of ids used for text events.

    Constant Field Values

### TEXT_VALUE_CHANGED

    public static final int TEXT_VALUE_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. This method throws an `IllegalArgumentException` if `source` is `null`.

  Parameters:
    `source` - the (`TextComponent`) object that originated the event
    `id` - an integer that identifies the event type
  Throws:
    `IllegalArgumentException` - if `source` is null

Method Detail

### paramString

    public String paramString()

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