I’m using this script on iOS directly inside a LC field object in order to get
a "delete button” to appear. (Ya, I know that is pretty ancient UI) But it
requires a swipe on iOS which is what you are after. I don’t think it is
responsive enough to do some of the fancy pushes that differentiate between
showing and sending things. It has been a long time since I worked on this (and
I chopped out a lot of code) so it is possible that I’ve missed something. FYI:
the field is a “List” field.
-- I use these values for swiping
put 40 into gHorizontalSwipeDistance
put 15 into gVerticalSwipeDistance
-- I'm assuming the list behavior of the field needs to be true
-- field script
on touchStart pID
put the mouseV into lMouseStartV
put the mouseH into lMouseStartH
-- some actions night need to go here
end touchStart
on touchMove pTouchID, pTouchH, pTouchV
-- see if there was a swipe for delete
if ((abs(pTouchH - lMouseStartH) > gHorizontalSwipeDistance)) AND\
(abs(pTouchV - lMouseStartV) < gVerticalSwipeDistance) then
-- they swiped
-- unhilite the line
set the hilitedLine of fld "ScrollingList" of cd "ListOfLists" to empty
-- do stuff here
end touchMove
on touchRelease pID
-- unhilite the line
set the hilitedLine of fld "ScrollingList" of cd "ListOfLists" to empty
end touchRelease
