-
How you implement this command is totally application dependent, but typical
strategies include:
-
Perform an inverse operation on the last modified piece of
data in the document. When redone, a copy of data stored in command
is pasted back or some operation reapplied. This relies on the fact that
Restore the entire document state (perhaps using document transactioning).
Potentially very inefficient, but possibly easier to code if the user interface
and data are complex, and an 'inverse execute' operation is hard to write.
-
The docview sample uses the first method, to remove or restore segments
in the drawing.
