When handling the repeat event, I add a constant delay to the event
structure, like this:
event->data.ctlRepeat.time += RepeatDelay;
The delay is defined as 0.2 seconds like this:
#define RepeatDelay (SysTicksPerSecond() / 5) /* 0.2 seconds */

trick was shown in this forum some time ago (see below).

Repeating buttons normally delay for you. It looks like the repeat
interval is 1/2 a second until it starts repeating, then about 10 times per
second (every 9 ticks) after that. ...that does seem sort of fast!
It's easy to slow it down. There's a value in the ctlRepeat event
(ctlRepeat.time) that controls when the next repeat event will be set. So
if you want to change the repeat interval to two times a second, just add
41 to the value stored there. (So it goes from an interval of 9 ticks to
one of 50 ticks.)
Of course, you should probably make these values dependent on the ticks per
second result, just for correctness.
