> Anyone know how to display a clock in a custom app? This is indeed not a trivial problem, if one is new to the PalmOS platform. I've had to solve a related problem myself (not displaying a timer, but doing something else "in parallel" while handling the controls of the form), so I have researched the issue.
Basically, the idea is the following: 1) In the event loop of your application, instead of EvtGetEvent (&event, evtWaitForever); use EvtGetEvent (&event, eventTimeout); where eventTimeout is a global variable, initialized with evtWaitForever. 2) As soon as the handler of your form that has to display the timer receives control, set eventTimeout to something small - e.g., SysTicksPerSecond() or less. Don't forget to set it back to evtWaitForever when you leave the form (i.e., on frmCloseEvent), or you'll drain batteries unnecessarily. Setting this variable to something small will force the OS to send you a nilEvent at least as often as the number of ticks specified in the eventTimeout. You might (and probably will) get them more often that that, though. 3) In the event handler of the form that has to display the timer, intercept the nilEvent event. Every time you get it, check how much time has passed since the last time you updated the timer. If the time passed is sufficient to mandate updating of the timer (e.g., one second), you update the timer; otherwise you do nothing. That's it. For further tips, see, for instance, this http://www.pikesoft.com/tips/how_to_do_regular_timed_events.htm or look at the OpenSource application TikTok; it displays various timers on a form.
