The back-end Demonstration

Palm OS App Development C++ - CodeWarrior, GNU Satellite Forms CASL Forms Pendragon Forms Visual Basic (Appforge) Java 2 Micro Edition Misc – nBasic, TinyC, Forth, etc.

POSE Palm OS Emulator Windows, Mac & Linux Uses ROM images Useful for debugging Gremlins CodeWarrior integration

POSE Demonstration

Databases Implemented as a collection of relocatable chunks of memory accessed via handles using Dm functions They have nothing to do with modern relational databases Saved by generic conduit as a .PDB file The developer determines record layout Less than 64k limit to record length Records may be Deleted or Archived

A simple C app Functions Resources Palm Main Application Event Handler Form Event Handler AppStart Message loop AppStop Resources

C app – PalmMain Check ROM version Check launch code Call AppStart Open first form Run the App Event Loop Call AppStop

C app - AppStart Open and/or Create database(s) Load preferences

C app - Message Loop static void AppEventLoop(void) { UInt16 error; EventType event; do EvtGetEvent( &event, evtWaitForever ); if ( ! SysHandleEvent( &event ) ) if ( ! MenuHandleEvent( 0, &event, &error ) ) if ( ! AppHandleEvent( &event ) ) FrmDispatchEvent( &event ); } while ( event.eType != appStopEvent ); }

C app - AppStop Save preferences Close Databases Close all open forms Clean-up

Web Clipping Index vs. Local vs. Remote pages Elaine Tags Tables QAB

Web Clipping – Tags <smallscreenignore> %deviceid %zipcode <META NAME="PalmComputingPlatform" CONTENT="TRUE"> <META NAME="PalmLauncherRevision" CONTENT="X"> <smallscreenignore> %deviceid %zipcode Frames aren’t supported

Web Clipping – Tables Tables are supported Palm OS devices have 160 pixel wide screens, fixed width tables could end up with horizontal scrolling

Web Clipping – QAB Query Application Builder Takes simple HTML and provides framework

QAB - Demo Demonstration
