Can a mouseclick simultaneously send a message as it ends a "repeat until the mouseclick" loop?

Hi Mark,

While I'm not using RunRev for multimedia purposes,
let's see what I can come up with...

First of all, let's redo the repeat loop and make it a
'send' loop. This should probably go in the card
script or somewhere similar:

local sTheSlideSendID
on doSlideThing
  global gMyWords, gTheTicks
  put word the random of gMyWords into fld myField
  -- other stuff
  -- ...
  -- now instead of 'wait' we use 'send ... in time'
  if "doSlideThing is not in the pendingMessages \
  then
    send "doSlideThing" to me in gTheTicks ticks
    put the result into sTheSlideSendID
  end if
end doSlideThing

on endSlideThing
  cancel sTheSlideSendID
end endSlideThing

This last handler will allow us to easily stop the
slide show loop from within another handler. Now we
rescipt the buttons so that they halt the slide show
and do something else.

on mouseUp
  if "doSlideThing" is in the pendingMessages then
    send "endSlideThing" to this card
  end if
  -- start something else
end mouseUp

This way the engine can return CPU-time to the OS in
between the showing of slides, unlike when you're
using the 'wait' command.
This tactic also avoids the 'repeat until mouseClick'
which would have similar effects ; plus, you don't run
the risk of the mouse having mopved to a different
spot in between your detecting the click and checking
where it is at that time.

Hope this helped,

Jan Schenkel.
