Sometimes the tips posted here may be a bit intimidating to folks who are
new to LiveCode, so here is a Back-to-Basics one.
A simple stack or card script handler to help smooth field scrolling with
the mouse-wheel...
----------------------------
--| If you already have a rawkeyDown handler in a field, make sure the last
--| line is "pass rawkeyDown" so it is activated higher up the message path
--| in your card or stack script.
on rawkeyDown tKey
constant numOfLines=5 --| Increase/decrease this number as required
if "field" is word 1 of the target then
put (the effective textHeight of the target)*numOfLines into tInc
if tKey=65309 then
set the scroll of (the target to the scroll of the target) - tInc
else if tKey=65308 then
set the scroll of (the target to the scroll of the target) + tInc
else pass rawkeydown
end if
end rawkeyDown
