Edittext - needs function or class

[Anonymous]

I've got a simpleUI here that passes a string from a edit text box to a function.

-- put everything in brackets
(
	local printIt
	
	rollout moveItRollout "" width:230 height:70
	(
		label lbl1 "Enter secret code" pos:[10,10] width:200 height:20
		editText edStr "" pos:[10,40] width:160 height:20
		button btnOK "Okay" pos:[180,40] width:40 height:20

		on btnOK pressed do
		(
			myString = edStr.text as string
			printIt myString
		)
		
		function printIt str =
		(
			print str
		)
	) -- end rollout
	
	createDialog MoveItRollout "" width:230 height:70
)

Only it keeps  the error : >> MAXScript Rollout Handler Exception: -- Type error: Call needs function or class, got: undefined

I don't know why? Any pointers please?

To get around this I've removed the function and but that part of the code within the on button pressed segment.

Probably the order in which things are delared as there's a fairly specific order when dealing with rollouts. This Maxscript help page should give you some clues.

This line is invalid:

printIt myString

It should be:

print myString

[Steve_Curley]

He's trying to call the printIt function just below passing myString as a parameter - that function has a print statement in it to do the actual printing.
As per the help page I linked, functions should come before event handlers which is what's causing the error (probably - I've not actually tested the code).

ah of course. yes as you've suggested if you move the PrintIt function above the button pressed then it will work.

Thanks for that. That's a good reference page as well, which I've managed to overlook because I was searching for "scope" and not "visibility" - which is for object paramaters and Wonder Woman's plane,  that sort of thing.

Not the snappiest title for page I would have to agree, but definitely one to remember 😉
