javafx.event.Event

javafx.scene.input.InputEvent

javafx.scene.input.InputMethodEvent

All Implemented Interfaces:

Serializable, Cloneable

public final class InputMethodEvent
extends InputEvent

An event which indicates that the underlying input method notifies its text change in a Node.

This event is delivered to the Node object that extends TextInputControl, when the text under composition (composed text) is generated/changed/removed, the input method commits the result text, or the input method caret position changes.

On receiving this event, the application is supposed to display the composed text with any visual feedback attributes to the user.

Note: this is a conditional feature. See ConditionalFeature.INPUT_METHOD for more information.

JavaFX 2.0

source - the source of the event. Can be null.

target - the target of the event. Can be null.

eventType - The type of the event.

composed - the text under composition

committed - the text that is committed as a result of composition

caretPosition - the current position of the caret.

Since:

JavaFX 8.0

InputMethodEvent

public InputMethodEvent(EventType<InputMethodEvent> eventType,
List<InputMethodTextRun> composed,
String committed,
int caretPosition)

Constructs new InputMethodEvent event with empty source and target.

Parameters:

eventType - The type of the event.

composed - the text under composition

committed - the text that is committed as a result of composition

caretPosition - the current position of the caret.

Since:

JavaFX 8.0

Method Details

getComposed

public final ObservableList<InputMethodTextRun> getComposed()

Gets the text under composition. This text should be displayed with the appropriate visual feedback that represents the InputMethodHighlights attached to each run.

Returns:

The text under composition

getCommitted

public final String getCommitted()

Gets the text that is committed by the input method as the result of the composition.

Returns:

The committed text

getCaretPosition

public final int getCaretPosition()

The input method caret position within the composed text. If the position is -1, the caret should be invisible.

Returns:

The input method caret position within the composed text

toString

public String toString()

Returns a string representation of this InputMethodEvent object.

Overrides:

toString in class EventObject

Returns:

a string representation of this InputMethodEvent object.

copyFor

public InputMethodEvent copyFor(Object newSource,
EventTarget newTarget)

Description copied from class: Event

Creates and returns a copy of this event with the specified event source and target. If the source or target is set to null, it is replaced by the NULL_SOURCE_TARGET value.

Overrides:

copyFor in class Event

Parameters:

newSource - the new source of the copied event

newTarget - the new target of the copied event

Returns:

the event copy with the new source and target

getEventType

public EventType<InputMethodEvent> getEventType()

Description copied from class: Event

Gets the event type of this event. Objects of the same Event class can have different event types. These event types further specify what kind of event occurred.

Overrides:

getEventType in class InputEvent

Returns:

the event type
