Hi, I was trying to change some preferences in the Exposé panel of the System Preferences via AS, but it’s gotten complicated. What I want to do is change a “Hot Corner”, then execute an app, and then restore it after I quit the app. The disctionary talks about panes, but I don’t know how to handle them…
I tried a few things like:
tell application "System Preferences"
try
set Paneles to get name of every pane
--set Paneles to get localized name of every pane
if "Exposé" is in Paneles then
tell preferences window to open (pane whose localized name is "Exposé")
else if "com.apple.preference.expose" is in Paneles then
tell preferences window to open (pane whose name is "com.apple.preference.expose")
end if
current pane
on error ElError
activate
display dialog ElError
end try
activate me
end tell
(*
tell application "System Events"
tell process "System Preferences"
keystroke "l" using command down -- doesn't work...
end tell
end tell
*)
but since the use of panes is a mistery to me… do you open panes, tell them things…:?:
Then I tried “clicking” the buttons:
-- choose file without invisibles
set BaseX to 30
set BaseY to 50
tell application "Finder" to open alias (((path to "dlib" from system domain) as text) & "PreferencePanes:Expose.prefPane:")
tell application "System Preferences"
set {TopX, TopY, BottomX, BottomY} to get bounds of window 1
set bounds of window 1 to {BaseX, BaseY, BottomX - TopX + BaseX, BottomY - TopY + BaseY}
end tell -- Just to relocate, nothing relevant.
delay 1
tell application "System Events"
tell process "System Preferences"
-- tell application "System Preferences" to activate
-- if "Hot Corner" is set to "Start Screen Saver" then
click at {495 - BaseX, 235 - BaseY} -- {X,Y} according to {0,0} of the window
click at {495 - BaseX, 285 - BaseY} -- This one shouldn't work, read foot note.
delay 1 -- set it to "Do Nothing"
click at {495, 235} -- {X,Y} according to {0,0} of the Mac screen
click at {495, 285} -- This one should work.
-- else if "Hot Corner " is set to "Do Nothing" then
click at {495 - BaseX, 235 - BaseY}
click at {495 - BaseX, 185 - BaseY}
delay 1 -- set it to "Start Screen Saver"
click at {495, 235}
click at {495, 185}
-- end commented if
end tell
end tell
activate me

System Events dictionary, Processes Suite:
click: cause the target process to behave as if the UI element were clicked
click UI element -- The UI element to be clicked.
[at list] -- when sent to a "process" object, the { x, y } location at which to click, in global coordinates
Result: UI element -- the reply for the command

but it doesn’t click, darn!! So I’m running out of options lol 
:?: !!
Anyone have any ideas? I’d appreciate them! Thanks a lot! And Merry Chistmas!
