Constructor Detail

• InputMethodEvent

  public InputMethodEvent(Component source,
                  int id,
                  long when,
                  AttributedCharacterIterator text,
                  int committedCharacterCount,
                  TextHitInfo caret,
                  TextHitInfo visiblePosition)

  Constructs an InputMethodEvent with the specified source component, type, time, text, caret, and visiblePosition.

  The offsets of caret and visiblePosition are relative to the current composed text; that is, the composed text within text if this is an INPUT_METHOD_TEXT_CHANGED event, the composed text within the text of the preceding INPUT_METHOD_TEXT_CHANGED event otherwise.

  Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.

  Parameters:

  source - the object where the event originated

  id - the event type

  when - a long integer that specifies the time the event occurred

  text - the combined committed and composed text, committed text first; must be null when the event type is CARET_POSITION_CHANGED; may be null for INPUT_METHOD_TEXT_CHANGED if there's no committed or composed text

  committedCharacterCount - the number of committed characters in the text

  caret - the caret (a.k.a. insertion point); null if there's no caret within current composed text

  visiblePosition - the position that's most important to be visible; null if there's no recommendation for a visible position within current composed text

  Throws:

  IllegalArgumentException - if id is not in the range INPUT_METHOD_FIRST..INPUT_METHOD_LAST; or if id is CARET_POSITION_CHANGED and text is not null; or if committedCharacterCount is not in the range 0..(text.getEndIndex() - text.getBeginIndex())

  IllegalArgumentException - if source is null

• InputMethodEvent

  public InputMethodEvent(Component source,
                  int id,
                  AttributedCharacterIterator text,
                  int committedCharacterCount,
                  TextHitInfo caret,
                  TextHitInfo visiblePosition)

  Constructs an InputMethodEvent with the specified source component, type, text, caret, and visiblePosition.

  The offsets of caret and visiblePosition are relative to the current composed text; that is, the composed text within text if this is an INPUT_METHOD_TEXT_CHANGED event, the composed text within the text of the preceding INPUT_METHOD_TEXT_CHANGED event otherwise. The time stamp for this event is initialized by invoking EventQueue.getMostRecentEventTime().

  Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.

  Parameters:

  source - the object where the event originated

  id - the event type

  text - the combined committed and composed text, committed text first; must be null when the event type is CARET_POSITION_CHANGED; may be null for INPUT_METHOD_TEXT_CHANGED if there's no committed or composed text

  committedCharacterCount - the number of committed characters in the text

  caret - the caret (a.k.a. insertion point); null if there's no caret within current composed text

  visiblePosition - the position that's most important to be visible; null if there's no recommendation for a visible position within current composed text

  Throws:

  IllegalArgumentException - if id is not in the range INPUT_METHOD_FIRST..INPUT_METHOD_LAST; or if id is CARET_POSITION_CHANGED and text is not null; or if committedCharacterCount is not in the range 0..(text.getEndIndex() - text.getBeginIndex())

  IllegalArgumentException - if source is null

• InputMethodEvent

  public InputMethodEvent(Component source,
                  int id,
                  TextHitInfo caret,
                  TextHitInfo visiblePosition)

  Constructs an InputMethodEvent with the specified source component, type, caret, and visiblePosition. The text is set to null, committedCharacterCount to 0.

  The offsets of caret and visiblePosition are relative to the current composed text; that is, the composed text within the text of the preceding INPUT_METHOD_TEXT_CHANGED event if the event being constructed as a CARET_POSITION_CHANGED event. For an INPUT_METHOD_TEXT_CHANGED event without text, caret and visiblePosition must be null. The time stamp for this event is initialized by invoking EventQueue.getMostRecentEventTime().

  Note that passing in an invalid id results in unspecified behavior. This method throws an IllegalArgumentException if source is null.

  Parameters:

  source - the object where the event originated

  id - the event type

  caret - the caret (a.k.a. insertion point); null if there's no caret within current composed text

  visiblePosition - the position that's most important to be visible; null if there's no recommendation for a visible position within current composed text

  Throws:

  IllegalArgumentException - if id is not in the range INPUT_METHOD_FIRST..INPUT_METHOD_LAST

  IllegalArgumentException - if source is null

Method Detail

• getText

  public AttributedCharacterIterator getText()

  Gets the combined committed and composed text. Characters from index 0 to index getCommittedCharacterCount() - 1 are committed text, the remaining characters are composed text.

  Returns:

  the text. Always null for CARET_POSITION_CHANGED; may be null for INPUT_METHOD_TEXT_CHANGED if there's no composed or committed text.

• getCommittedCharacterCount

  public int getCommittedCharacterCount()

  Gets the number of committed characters in the text.

• getCaret

  public TextHitInfo getCaret()

  Gets the caret.

  The offset of the caret is relative to the current composed text; that is, the composed text within getText() if this is an INPUT_METHOD_TEXT_CHANGED event, the composed text within getText() of the preceding INPUT_METHOD_TEXT_CHANGED event otherwise.

  Returns:

  the caret (a.k.a. insertion point). Null if there's no caret within current composed text.

• getVisiblePosition

  public TextHitInfo getVisiblePosition()

  Gets the position that's most important to be visible.

  The offset of the visible position is relative to the current composed text; that is, the composed text within getText() if this is an INPUT_METHOD_TEXT_CHANGED event, the composed text within getText() of the preceding INPUT_METHOD_TEXT_CHANGED event otherwise.

  Returns:

  the position that's most important to be visible. Null if there's no recommendation for a visible position within current composed text.

• consume

  public void consume()

  Consumes this event so that it will not be processed in the default manner by the source which originated it.

  Overrides:

  consume in class AWTEvent

• isConsumed

  public boolean isConsumed()

  Returns whether or not this event has been consumed.

  Overrides:

  isConsumed in class AWTEvent

  See Also:

  consume()

• getWhen

  public long getWhen()

  Returns the time stamp of when this event occurred.

  Returns:

  this event's timestamp

  Since:

  1.4

• paramString

  public String paramString()

  Returns a parameter string identifying this event. This method is useful for event-logging and for debugging. It contains the event ID in text form, the characters of the committed and composed text separated by "+", the number of committed characters, the caret, and the visible position.

  Overrides:

  paramString in class AWTEvent

  Returns:

  a string identifying the event and its attributes
