Cut/Paste Commands

[Jason Cavett]

If I want to setup an application that I am developnig so cut and paste
are able to part of undo/redo, do I need to implement them on my own
within my Command pattern (even though they are already handled by
default) or is there some easier way to do this?


Thanks

When a cut or paste happens, to support undo/redo via the command
pattern, you would only need to store where the cursor was, and what the
contents of the clipboard were at the time the command was issued. So you
could use the existing implementation of cut and paste assuming you can add
hooks to immediately scan the clipboard and cursor position when those
commands are invoked.

Okay, I'll give that a shot. Thanks Oliver.
