Hi.
Are you asking if there is a way to make the scroll of a field track the mouseLoc? If so, then you are right to use the "mouseMove" message, and scale the y-value of its included parameter to the vScroll of the field.
Or am I missing it?

To scroll a field on mobile I'm going to try this:
on createQuoteScroller
local tScrollerRect,tContentRect,sScrollerID
if environment() is not
"mobile" then exit createQuoteScroller
mobileControlCreate "scroller",
"quoteScroller"
put the result into sScrollerID
put the rect of fld
"quote" into tScrollerRect
put the topleft of fld "scrollMe" & "," & the
right of fld
"scrollme"&","&( the top of fld "scrollme" + the formattedHeight
of fld
"scrollme") into tContentRect
mobileControlSet "quoteScroller",
"rect", tScrollerRect
mobileControlSet "quoteScroller", "contentRect",
tContentRect
mobileControlSet "quoteScroller", "visible", true
mobileControlSet "quoteScroller", "scrollingEnabled", true
mobileControlSet
"quoteScroller", "vIndicator", true
mobileControlSet "quoteScroller",
"vscroll", 0
end createQuoteScroller
on scrollerDidScroll hOffset, vOffset
// When the user scrolls move the displayed content
set the vScroll of fld
"quote" to vOffset
end scrollerDidScroll
but how do we emulate this with the
mouse?
on mouseMove
end mouseMove
would seem to be our best tool
but
how to translate the mouseloc into vScroll of the field?
on mouseMove
put the mouseloc
end mouseMove
have to sleep on that one... but perhaps
someone else already build
this...
