Properties
| RedoStack |
Gets the current entries on the redo stack, ordered most to least recent. |
| UndoStack |
Gets the current entries on the undo stack, ordered most to least recent. |
Methods
| Add(IOleUndoUnit) |
Pushes the specified undo unit onto the undo stack. |
| AddOrMerge(IMergeableUndo) |
Adds an undo unit to the undo stack, potentially merging it with other undo units on the stack or dropping it if it's empty. If it has UndoOption.AddForce then it will always be added even if it is empty. This is handy for compound operations like moving nodes, drag/drop or label editing where you merge a series of undo units into one atomic unit and you need to have a sure way of starting with the Add unit even if it's initially empty. |
