Scrolling text w/o scroll bars in iOS

[Randy Hengst]

Steve and Jacque,


Steve I did it using the script below in the text field… no scroll bar shows….

but, Jacque, I'd love to see a specific example of scrolling one text field with the iOS scroller showing. I really haven't been able to organize the overlay deal.

local tScollField
local tStartY

on mouseDown
   put item 2 the clickLoc into tStartY
   put tStartY
   put "yes" into tScollField
end mouseDown

on mouseMove x,y
   if tScollField = "yes" then
      set the vscroll of target to (the vScroll of target) - (y-tStartY)
   end if
end mouseMove

on mouseUp
   put "no" into tScollField
end mouseUp

on mouseRelease
   mouseUp
end mouseRelease



take care,
randy hengst
