The menu is defined to have only one PULLDOWN and that puldown has only one MENUITEM. This menu is added to the MainForm with the MENUID.

And as usual the identifiers are defined in the helloworld_rcp.h-file:

helloworld_rcp.h
`// Defines for the Hello world application #define MainForm 1000 #define MainHelloButton 1010 #define MainMenuBar 2000 #define HelloAboutMenuItem 2010`

The code to handle menu events is added to the event loop:

helloworld.c
#include "helloworld.h" // Initialises the application Boolean StartApplication(void) { // Start the main form FrmGotoForm(MainForm); return false; } // StartApplication // terminates the application void StopApplication(void) { FrmCloseAllForms(); } // StopApplication // Entry point for palm applications DWord PilotMain(Word cmd, Ptr cmdPBP, Word launchFlags) { // Variable declarations EventType event; Word error; // Check the launch code if (cmd == sysAppLaunchCmdNormalLaunch) { // Initialise the application if (0 == StartApplication()) { do { // Wait until something happens EvtGetEvent(&event, evtWaitForever); // Let the system handle the event if (!SysHandleEvent(&event)) { // Menu events if (!MenuHandleEvent(0, &event, &error)) { // Check if the form was changed if (!ApplicationHandleEvent(&event)) { // Handle events for the current form FrmDispatchEvent(&event); } } } // Quit if we have received an appStopEvent } while (event.eType != appStopEvent); StopApplication(); } } // cmd == sysAppLaunchCmdNormalLaunch return; } // PilotMain

helloworld.c

#include "helloworld.h" // Initialises the application Boolean StartApplication(void) { // Start the main form FrmGotoForm(MainForm); return false; } // StartApplication // terminates the application void StopApplication(void) { FrmCloseAllForms(); } // StopApplication // Entry point for palm applications DWord PilotMain(Word cmd, Ptr cmdPBP, Word launchFlags) { // Variable declarations EventType event; Word error; // Check the launch code if (cmd == sysAppLaunchCmdNormalLaunch) { // Initialise the application if (0 == StartApplication()) { do { // Wait until something happens EvtGetEvent(&event, evtWaitForever); // Let the system handle the event if (!SysHandleEvent(&event)) { // Menu events if (!MenuHandleEvent(0, &event, &error)) { // Check if the form was changed if (!ApplicationHandleEvent(&event)) { // Handle events for the current form FrmDispatchEvent(&event); } } } // Quit if we have received an appStopEvent } while (event.eType != appStopEvent); StopApplication(); } } // cmd == sysAppLaunchCmdNormalLaunch return; } // PilotMain

When the menu in the application is selected, it looks like this:
