Class JTextComponent.MutableCaretEvent

java.lang.Object
  java.util.EventObject
      javax.swing.event.CaretEvent
          javax.swing.text.JTextComponent.MutableCaretEvent

All Implemented Interfaces:

Enclosing class:

JTextComponent

static class JTextComponent.MutableCaretEvent

extends CaretEvent

implements ChangeListener, FocusListener, MouseListener

Event to use when firing a notification of change to caret position. This is mutable so that the event can be reused since caret events can be fairly high in bandwidth.
