Applescript script for toggling applications in and out of fullscreen mode.

makeFullScreen.applescript

on run argv
  (*
    Toggle an application from full screen to non full screen (or the reverse).
    Parameters:
      1: application name(ie, Chrome)
      2: boolean (true/false).
         When true ensure that the application is in full screen mode (if not, make it so)
         When false ensure that the application is NOT in full screen mode (if not, make it so)
  *)
  set theapp to item 1 of argv
	if item 2 of argv is "false"
    set toggleOnFull to true
	else
    set toggleOnFull to false
	end if

  tell application theapp
    activate
    delay 2

    *)
    set isfullscreen to false
    tell application "System Events" to tell process theapp
      set isfullscreen to value of attribute "AXFullScreen" of window 1
    end tell
    --display dialog "var " & isfullscreen

    if isfullscreen is toggleOnFull then
      tell application "System Events" to keystroke "f" using { command down, control down }
      delay 2
    end if
  end tell
end run

Requires enabling "Enable access for assistive devices". In Mountain Lion that can be found in the Accessibility System Preference item.

Hi there, I am using this in Mavericks - and use QuickSilver trigger to run the script from keyboard shortcut.

It works fine when I run it from the AppleScript Editor, but from the keyboard trigger i randomly (it seems) get this error:

26/04/2014 9:58:37.126 am Quicksilver[15188]: Run Script: System Events got an error: Can’t get window 1 of process "Terminal". Invalid index.

My script I have used, changing your slightly is:

on run argv

set toggleOnFull to false

set myList to {"Google Chrome", "Safari", "Firefox", "Mail", "Skype", "Terminal", "Sublime Text", "Calendar"}
repeat with theItem in myList

    tell application theItem
        activate
        delay 3
        (* 
  Initially from http://stackoverflow.com/questions/8215501/applescript-use-lion-fullscreen
*)
        set isfullscreen to false
        tell application "System Events" to tell process theItem
            set isfullscreen to value of attribute "AXFullScreen" of window 1
        end tell
        --display dialog "var " & isfullscreen

        if isfullscreen is toggleOnFull then
            tell application "System Events" to keystroke "f" using {command down, control down}
            delay 4
        end if
    end tell

end repeat

end run

Any ideas on why this message appears?

Kind regards, Steve
