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.
