Edge Constraint Toggle

Hi guys!

So, I started to make a script that basically shows me on the UI if the edge constraint it ON or OFF on the selected object.

Basically I have it as a button on the UI, and when I have an object selected and I press the button It toggles it and enables Edge constraint to edge and stays lit up. But when I deselect the object the toggle is still on.

Would it be possible for the Toogle button to make the test on the object i select and see if the edge constraint is on and toggle it acordingly.
Obviously if its a group of object it wouldnt do anything, i think.

This is what i have.

macroScript test category:"Tests"
(
	local isOn = false --initialize to false (closed)
 
	on execute do (
		if ( $ != undefined) then (
			if isOn == true then ( --if open, close it
				isOn = false--and lower the flag
				$.constrainType = 0
			) else ( --if closed, open it
				$.constrainType = 1
				isOn = true --and raise the flag
			)
		)
	)
		on isChecked return isOn --return the flag
)

i have both the script as a button and a shortcut, so basically it runs the script on the object and togles the button on or off.

Cheers!
