36 Timers documentation
\r
38 Call setTimer to set a timer.... cancelTimer to delete a running timer.
\r
39 Derive your object from TimerReceiver (timerreceiver.h), implement timercall() in your class
\r
40 and supply your 'this' pointer to setTimer.
\r
42 Once a timer has fired it does not exist anymore, you have to keep creating them if you want
\r
45 clientReference is any int of your choice. It will be supplied back to you in the timercall()
\r
46 so you can identify which timer has fired if you have more than one.
\r
48 You can reset a timer by calling setTimer again. This will not create 2 timers, it will overwrite the first one.
\r
50 You must not allow a timer to fire on an object that has been deleted already, unless you want
