Class 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.

    • 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.

      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 Event
      Returns:
      the event type
