- Sub: MacApp Undo model
-
- It seems to me that the MacApp model of undoable commands is inconsistent
- from the user's point of view: How do you explain in the user manual how
- Undo works?
- It is clear that only commands that modify a document are undoable.
- It is also clear that a second command that modifies the document
- commits the first one. What if the second command does not
- modify the document? Sometimes (e.g. Select All), Undo still works.
- Some other times (e.g. Print or Save) it does not.
- I understand that calling gLastCommand.Commit before printing or
- saving to disk is a great simplification for the developer, but
- should we not consider consistency of the interface before ease
- of programming?
