Thank you Trevor for making this available. After testing your library i
realize what an improvement it is.
And I agree that "ideally any engine improvents would tap into the scroll wheel
values provided by the OS"
I don't see any difference regarding lineSize. Maybe
"ObjC_NSEventHasPreciseScrollingDeltas" is true.
Anyway in the comments of the LCB file you mention "row height"
Do you mean "effectiv lineSize" (synonym of borderSize) or "effective
textHeight"?
I added hScroll to your script (again this is Mac only and needs Trevor's
library installed)
-------------------------------------------
on rawKeyDown pKey
-- if the optionKey is down then pass rawKeyDown -- just to test scrolling
of LC and library
if pKey = "65308" or pKey = "65309" then
set the vscroll of me to the vscroll of me \
- item 2 of macCurrentEventScrollValues(the effective linesize of me)
else if pKey is in "65310,65311" and the hScrollbar of me then
set the hscroll of me to the hscroll of me \
- item 1 of macCurrentEventScrollValues(the effective linesize of me)
else
pass rawKeyDown
end if
end rawKeyDown
--------------------------------------------
Kind regards
Bernd
