RedoAction

Inside Macintosh: OpenDoc Class Reference /: Part 1 - Classes and Methods / ODPart

RedoAction
The RedoAction method should redo the specified action.
void RedoAction (in ODActionData actionState);
actionState
A byte array whose buffer contains the data previously logged by this part to allow it to redo the action.

DISCUSSION
A part may need to give the user the capability of repeating the effects of recently undone commands. OpenDoc calls this method when the user chooses to redo an action of this part.
Your part is responsible for notifying the clipboard whenever a Cut, Copy, or Paste operation is done, undone, or redone. If your part's RedoAction method is called, it should remove the object from its content model and notify the clipboard that the cut was redone.

OVERRIDING
When you subclass ODPart, you can override this method. Your override method must not call its inherited method; that is, your override method must implement this method's functionality completely.

EXCEPTIONS

kODErrDoesNotUndo
