I originaly asked this question. Thanks to those who gave me clues.
here's how i manage to do that :
static void AppEventLoop(void){
Word error;
EventType event;
do{
EvtGetEvent(&event, evtWaitForever);
if (event.eType == keyDownEvent && (event.data.keyDown.chr ==
autoOffChr || event.data.keyDown.chr == hardPowerChr)){
// do what you want when power off
}
if (! SysHandleEvent(&event)){
if (! MenuHandleEvent(0, &event, &error)){
if (! AppHandleEvent(&event)){
FrmDispatchEvent(&event);
}
}
}
} while (event.eType != appStopEvent);
}
