Design Summary

By now, you should have a good feel for how to design a Palm application and conduit. We showed you the Palm OS UI objects and a range of applications in which they are implemented. We talked about important placement and performance rules and showed you some well-designed forms, dialog boxes, and alerts. Last of all, we covered the Sales sample application that we will be building over the course of this book. We discussed the design decisions we faced and the choices that we made. We tried wherever possible to remember these important rules for designing for a Palm application:

Keep it clean

Minimize screen clutter by hiding infrequent actions.

Keep it fast

Minimize the number of taps to complete frequent actions (the 80/20 rule).

Make it easy

Provide command buttons for common multistep activities.

Be clever

Take advantage of the unique aspects of your application to make for a better user experience.

Now it’s time to take everything you have learned and apply it. It’s time to write some code.
