- .Evolving an Application: Data Entry Dialog, Application level
-
- COMMENTS
- --------
- This series of demos takes a Vision object from Application level to
- an encapsulated, independent object.
-
-
- UPSIDE
- ------
- We've got a dialog on the screen, which can be modified with
- the Dialog Editor. The record commands don't interfere, should we
- want to add History Lists later. And, we've got a hint for each field
- in the dialog.
-
- DOWNSIDE
- --------
- "Edit" mode is always active; the user could accidentally type some
- keys and over-write data. Also, all the action (events) is handled
- by the Application; they really should be encapsulated into the
- object.
