Hi Xformers,
Quick mini-snag which someone may have helpful advice about...
I'm using a standard timer with which resets itself at the end of its
own call-back, therefore re-triggering itself (a 'heartbeat').
This works beautifully, except when there is a lot of other stuff
happening grabbing CPU time, then the timer starts piling up
call-backs, which all get serviced in a rush when there is a gap in
the processing time.
I can't seem to lengthen the timer easily when I know this will
happen, and I'm not certain how best to use the X-event queue
manipulation stuff.
Temporarily disabling the timer outside the 'hearbeat' callback also
seems also pretty hard (perhaps I've answered my own question.. use a
global to signify what should happen to the timer delay in the
heatbeat callback?)
Any advice gratefully received,
Thanks, Hugh Gibson
