Timer Control

This document covers the following topics:


Description

A timer is a dialog element which is invisible to the end user but which allows events to be triggered periodically in the dialog. You can, for example, update the STRING attribute of a text constant control with the Click Event of a timer.

Example:

#TC-1.STRING:= *TIMX 
/* Display the system time in the text-constant
/* control #TC-1 and  update the time (= timer /* control click event) every 1000 milliseconds 
/* (TIMER-INTERVAL attribute).

Note:
It is not recommended to write code that counts clicks in the timer click-event handler, because the click events that occur while the system is busy may get lost.
