Constructor Detail

InputMethodEvent

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

Suppressed: 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.

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

Since:

1.4

InputMethodEvent

public InputMethodEvent(Component source,
                        int id,
                        java.text.AttributedCharacterIterator text,
                        int committedCharacterCount,
                        java.awt.font.TextHitInfo caret,
                        java.awt.font.TextHitInfo visiblePosition)

Suppressed: 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 java.awt.EventQueue#getMostRecentEventTime().

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

InputMethodEvent

public InputMethodEvent(Component source,
                        int id,
                        java.awt.font.TextHitInfo caret,
                        java.awt.font.TextHitInfo visiblePosition)

Suppressed: 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 java.awt.EventQueue#getMostRecentEventTime().

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

Method Detail

getText

public java.text.AttributedCharacterIterator getText()

Enabled: 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()

Enabled: Gets the number of committed characters in the text.

getCaret

public java.awt.font.TextHitInfo getCaret()

Enabled: 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 java.awt.font.TextHitInfo getVisiblePosition()

Enabled: 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()

Enabled: 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()

Enabled: Returns whether or not this event has been consumed.

paramString

public String paramString()

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

Returns:

a string identifying the event and its attributes
