macOS Changing Scrolling Speed with Applescript - Problem

[Jolly Jimmy]

I'm trying to write an applescript to set the scrolling speed in the trackpad preferences. The script works for setting the tracking and double-click speed but for some reason it won't for the scrolling speed.

Here's what I've got :

----------

tell application "System Preferences"
activate
set current pane to pane "com.apple.preference.trackpad"
end tell
tell application "System Events"
set value of slider "Scrolling Speed" of window "Trackpad" of process "System Preferences" to 2
end tell

----------

Out of the three sliders in the trackpad preferences, "Scrolling speed" is the only one that the script won't work on.

Any help is much appreciated.

Running OS X 10.6.4 on a non-unibody MacBook.

I hate to bump an old thread, but I too was having the same problem. I came across this page on Google looking for the solution. I played around with your script and have solved it through guessing the value of the slider.

tell application "System Preferences"
activate
set current pane to pane "com.apple.preference.trackpad"
end tell
tell application "System Events"
set value of slider 3 of window "Trackpad" of process "System Preferences" to 2
end tell

For some reason it is the third slider and not the second.

set value of slider "Scrolling Speed" of window "Trackpad" of process "System Preferences" to 2

You missed a tab group.
This works for me:

set value of slider "Tracking Speed" of tab group 1 of window "Trackpad" of application process "System Preferences" to 2

Oh, 10.6.4.
My answer was for Lion.

The easiest way I've found to get the correct phrasing for a line like that is to get it from a script like this one:

-- Entire Contents Demo - mini
-- BP ages ago or so

-- This'll get all the controls and structures associated with an App's window and menus
-- In a form which is easily pasteable into your own scripts
-- and show them in the result pane below.
--
-- Copy that into a text editor and change commas to returns to get an easily  readable list.
--
-- The script can take a long time if there are LOTS of window items, such as
-- in the "music" pane of iTunes. It may even time out if you have a huge iTunes library
-- The script'll process most App's UI structures in under a minute

set appname to "System Preferences" -------------------------- Set this to the App you want to look at

set winstuff to "defaultval"
set menustuff to "defaultval"

tell application appname
	activate
end tell

tell application "System Events"
	tell process appname
		set winstuff to entire contents of front window
		set menustuff to entire contents of menu bar 1
	end tell
end tell
--return winstuff & "\r\r\r\r" & menustuff -- comment this out to get just winstuff
return winstuff -- comment this out too to get just menustuff
--return menustuff
