Distinguishing between tap and swipe

Hi BR,

I’ve not used swipe a lot, but here is how I have used it to “erase” from a text field… the app is iOS iPad only. Below is the script of the text field.  It works quickly without a noticeable delay.

local tStartLocX, tEndLocX

on mouseDown
   put the short name of target into tTargetFieldToClear
   put item 1 the mouseLoc into tStartLocX
end mouseDown

on mouseUp
   lock screen

   put item 1 the mouseLoc into tEndLocX

   if tEndLocX + 10 < tStartLocX then
      put empty into target
   end if

   unlock screen
end mouseUp

be well,
