Class ConfigurableCaret

  • All Implemented Interfaces:
    FocusListener, MouseListener, MouseMotionListener, Shape, Serializable, Cloneable, EventListener, Caret
    public class ConfigurableCaret
extends DefaultCaret
    The caret used by RTextArea. This caret has all of the properties that javax.swing.text.DefaultCaret does, as well as adding the following niceties:
    • This caret can render itself many different ways; see the setStyle(CaretStyle) method and CaretStyle for more information.
    • On Microsoft Windows and other operating systems that do not support system selection (i.e., selecting text, then pasting via the middle mouse button), clicking the middle mouse button will cause a regular paste operation to occur. On systems that support system selection (i.e., all UNIX variants), the middle mouse button will behave normally.
