Methods
Extends
Override this method to indicate this action extends another action, and can thus be dropped from a sequence of actions.
Parameters:
| action (Action) |
PerformRedo
Redo this action. This is only allowed if the Action.State equals State.Redo.
Parameters:
| doc (Document) |
PerformUndo
Undo this action. This is only allowed if the Action.State equals State.Undo.
Parameters:
| doc (Document) |
PrepareRedo
Run the preperatory work for a redo operation. The Action.PerformRedo(Document) method ought never be called without a preceding call to Action.PrepareRedo(Document), although note that a call to Action.PrepareRedo(Document) is not necessarily followed by a call to Action.PerformRedo(Document).
Parameters:
| doc (Document) |
PrepareUndo
Run the preperatory work for an undo operation. The Action.PerformUndo(Document) method ought never be called without a preceding call to Action.PrepareUndo(Document), although note that a call to Action.PrepareUndo(Document) is not necessarily followed by a call to Action.PerformUndo(Document).
Parameters:
| doc (Document) |
