proportional window scale on resize ?

Scripting Forums AppleScript Studio & Xcode
#1

Within Interface Builder I’d like to be able to create a window that allows the user to resize, but will maintain it’s current aspect ratio. How can I lock the proportion without locking the window size itself?

#2

Connect both of the following handlers to the window and add the ‘winProportion’ property to the script’s head…

property winProportion : 0

on awake from nib theObject
	set {winWidth, winHeight} to size of theObject
	set winProportion to (winWidth / winHeight)
end awake from nib

on will resize theObject proposed size proposedSize
	set {tmpWidth, tmpHeight} to proposedSize
	return {tmpWidth, (tmpWidth / winProportion)}
end will resize

Works like a charm. Thanks.
