How the Sample Applications Are Useful
Some of you may be wondering how useful the Sales application will be to you. Does it show you how to implement all the APIs? Does it contain the essential components of most Palm applications? Here are some answers. The Sales application uses most of the Palm API (except for Category UI) and to that extent offers a broad treatment. Because it isn’t an exact clone of the built-in apps, you also see some new design issues and code. It also covers databases, beaming, menus, dialog boxes, and Find. Another crucial component is the detailed description of its conduit. We hope that much of what is mystifying about conduits is clarified in our descriptions and the code we create.
We also cover some Palm OS features in smaller sample applications. We handle tables, barcoding, serial, and TCP/IP in this manner. The bad news is that the Palm OS is so feature-rich that there are indeed some other areas we don’t cover in this detail. We hope there are no glaring omissions. Our goal was not to cover every topic but only the most difficult or important ones. Our examples are created with this goal in mind. (If we goofed, let us know and we will try to correct it in the future.)
