Choose expansion level from Absolute/Relative list Thread Tools Search this Thread Display Modes
Prev Previous Post   Next Post Next
A variant of the expand & collapse scripts in an earlier post which offers a list of expansion options for the front document.

Options are listed in both relative and absolute terms.

(The default selection shows the deepest current level of expansion).

Can also be used through LaunchBar. Choose the script with a LaunchBar abbreviation, and tap the space-bar to pass arguments like 1, 2, 3 etc. to increase the level of expansion by one two or three levels, or -1, -2, -3 etc to collapse by some degree.

property pTitle : "Expand / Collapse Outline"
property pVer : "Ver .03"

-- For use from LaunchBar to increase or decrease expansion level
on handle_string(strChange) -- e.g.  1, 2, 3 or -1, -2 -3 etc
		set lngDelta to strChange as integer
	on error
	end try
end handle_string

-- For use through a dialogue
on run
end run

on GetDelta()
	tell application id "OOut"
		set oDoc to front document
		set lngDeepest to (my DeepestLevel(oDoc, false))
		set lngDeepestExpanded to (my DeepestLevel(oDoc, true))
		set lstOptions to {}
		repeat with i from 1 to (lngDeepest)
			set lngDelta to (i - lngDeepestExpanded) - 1
			set strDelta to lngDelta as string
			if lngDelta > 0 then
				set strOption to ("+" & strDelta & "    (Level " & i as string) & ")"
			else if lngDelta = 0 then
				set strOption to ("0      (Level " & i as string) & ")"
				set strDefault to strOption
				set strOption to (strDelta & "    (Level " & i as string) & ")"
			end if
			set end of lstOptions to strOption
		end repeat
		set varChoice to choose from list lstOptions with title pTitle & "  " & pVer with prompt "Choose level of expansion" default items {strDefault}
		if varChoice is false then return 0
		set my text item delimiters to space
		(first text item of (first item of varChoice)) as integer
	end tell
end GetDelta

on AdjustExpansion(lngDelta)
	tell application id "OOut"
		if (count of documents) < 1 then return
		set oDoc to front document
		set lngNewMax to (my DeepestLevel(oDoc, true)) + lngDelta
		tell oDoc
			set expanded of (rows where level ≤ lngNewMax) to true
			set expanded of (rows where level > lngNewMax) to false
		end tell
	end tell
end AdjustExpansion

on DeepestLevel(oDoc, blnExpandedOnly)
	set lngMax to 0
	tell application id "OOut"

			set lstLevel to level of rows of oDoc
