Class MyUndoManager

  • All Implemented Interfaces:
    java.io.Serializable, java.util.EventListener, javax.swing.event.UndoableEditListener, javax.swing.undo.UndoableEdit
    public class MyUndoManager
extends javax.swing.undo.UndoManager
    An UndoManager that can handle the double undo and redo that is created by a JTextComponent.setText(String) call.
    The double undo is a remove (all) and a insert (all). These are combined by this UndoManager.
    NOTE: The nextUndoIsDouble() method MUST be MANUALLY called before the call to JTextComponent.setText(String)!
    Or the two undos must be executed fast (< 1msec) after each other (and FAST_EDITS_ARE_THE_SAME_EDIT = true).
    Fast like selecting text and then start writing. This is with this UndoManager also only one undo / redo.
