In essence, you want something like the following:
(this assumes a capital Q typed to the card will quit the display. It
could easily be changed to clicking a button - so long as the mouseUp
handler would set the script-local when appropriate).
local sStopRequested
command playShow
local tPhotos
put FALSE into sStopRequested
put randomPhotoList() into tPhotos
repeat for each line L in tPhotos
dispatch "loadImage" with L
wait 5 seconds with messages
if sStopRequested then exit repeat
end repeat
dispatch "loadImage" with "defaultMainImage"
end playShow
on rawKeyUp pKey
if pKey = "Q" then
put TRUE into sStopRequested
else
pass rawKeyUp
end if
end rawKeyUp
NB this has the limitation that there will be a delay of up to 5 seconds
after the user types the 'Q" before it takes effect. If you need to
avoid that and get more immediate response, then you could replace
wait 5 seconds with messages
if sStopRequested then exit repeat
with
repeat 5 times
if sStopRequested then exit repeat
wait 1 second with messages
end repeat -- for the number of seconds
if sStopRequested then exit repeat
or similar (or put that logic into a handler).
And as a bonus, you could easily add more typing options ...
Q for quite the slideshow
SPACE for next photo immediately
arrowkey for next/previous, erc
