Is there any way to apply "Fix Width" (Cmd+J or Object>Fix Width) to an object using JavaScript? i need it to measure the width of a text label in a comment object (in its minimal expression) and don't know how to do that using JS.

I think one way is to shorten the length of the comment until it reaches the double of its height (two lines) and then use the previous value, but it would be sort of pain in the ass if there's a shortest way

I have no idea ... but ! u can measure text in JSUI ! there is method for it . U could ommit Comment box and use JSUI for displaying text ! If u have no idea how to deal with JSUI i might find some time for it

Hello !
I have no idea ... but ! u can measure text in JSUI ! there is method for it . U could ommit Comment box and use JSUI for displaying text ! If u have no idea how to deal with JSUI i might find some time for it


I didn't now know JSUI could do that..thank you again DO...WHILE!

just let me know one thing ... will u send text to it or u want to type text too ?

i'll send text to change the content but not by typing like textedit

This works just fine for what i need (1 line comments):

function fix_width(obj)
    {
        var target = this.patcher.getnamed(obj);
        var dims = target.getattr("patching_rect");
        
        var x = dims[0];
        var y = dims[1];
        var height = dims[3];
        var width = dims[2];
        
        var new_width = width-1;
        var new_height = height;
        
        while(height == new_height)
            {
                target.message("patching_rect", x, y, new_width, width);
                
                dims = target.getattr("patching_rect");
                new_height = dims[3];
                new_width = dims[2]-1;
            }
        
        target.message("patching_rect", x, y, new_width+2, height);
    }



function fix_width(obj)
	{
		var target = this.patcher.getnamed(obj);
		var dims = target.getattr("patching_rect");
		
		var x = dims[0];
		var y = dims[1];
		var height = dims[3];
		var width = dims[2];
		
		var new_width = width-1;
		var new_height = height;
		
		while(height == new_height)
			{
				target.message("patching_rect", x, y, new_width, width);
				
				dims = target.getattr("patching_rect");
				new_height = dims[3];
				new_width = dims[2]-1;
			}
		
		target.message("patching_rect", x, y, new_width+2, height);
	}



i need it to measure the width of a text label

Thank you indeed, i'll explore JSUI watching your patch :)

I got a problem with my script while creating objects using JS, why is this??

The problem is not exactly related with the script, the problem is that the 

 seems to be 0...if you see Max Window, the last number is always 0 and 

 is wrong according to Inspector too...am i missing a param in the function?

function test()
    {
        var test = this.patcher.newdefault(100,100, "comment");
        test.message("set", "SUP GUYS, IMA COMMENT BOX");
        
        post(test.getattr("patching_rect"));
        post();
    }

		test.message("set", "SUP GUYS, IMA COMMENT BOX");
		
		post(test.getattr("patching_rect"));
		post();
	}



its because u get the attribute too fast , which is not obvious ... the thing is that the height is set according to the text size . there is some thread confusion on the initialization . When u will call another function that will be responsive for retrieving this attribute , u will get the right value .

 it back to JS in order to update variables :/

Two possibilities : Use Task Class , OR send message out of JS and deferlow it back to JS in order to update variables :/


got it! thank you again...if i use a separated function recalled after the one that creates the object it works well

i deleted what i wrote in JS, but was something like this:

function test()
    {
        var test = this.patcher.newdefault(100,100, "comment");
        test.message("set", "SUP GUYS, IMA COMMENT BOX");
                test.varname = "sup";
    }

function test2(obj)
        {
                var target = this.patcher.getnamed(obj);
                post(target.getattr("patching_rect"));
        }


I called test first and then test2, both of them from outside JS...like 2 message boxes, one 

function test()
	{
		var test = this.patcher.newdefault(100,100, "comment");
		test.message("set", "SUP GUYS, IMA COMMENT BOX");
                test.varname = "sup";
	}

function test2(obj)
        {
                var target = this.patcher.getnamed(obj);
                post(target.getattr("patching_rect"));
        }

all right , good to know . thats smart to lookup for the object at the second call , its thread separated .

Actuallyyyy ! when u call both functions from outside those are queued so perhaps second function wont start until first finishes. u can store reference via first call into variable , and just use it within next function call without the lookup . lookup is expensive if u want to make it often . just check what u prefer best .

 in JS ! just to be aware that u still can do all in one procedure .

Task is your deferlow in JS ! just to be aware that u still can do all in one procedure .


Thank you! i'm running out of time for Max right now, but i will do some test next time, it's been a very helpful topic for me..so Task is the next stop :)

 more than 7 years ago. I need to revisit it and tidy it up, but as far as I know it still works in Max 7, Max 6 and Max 5...

In case it's of any help: I wrote this thing more than 7 years ago. I need to revisit it and tidy it up, but as far as I know it still works in Max 7, Max 6 and Max 5...


Is it possible to deliver a var to a function inside a task? i mean, like:

var tsk = new Task(myshittyfunc(custom_argument), this);
//I want this var instead of:
var tsk = new Task(myshittyfunc, this);
tsk.interval = 5000;
tsk.repeat(20);


i know globals could do the job but i want to try another way if exists

Thanks NICK TOTHWELL / CASSIEL, i'll check it!

 is your function argument ! it can ether be array of arguments or an object . Dont know about the single variable , ive always used 

 as variable container due to reference nature .

Hi !
third argument for task is your function argument ! it can ether be array of arguments or an object . Dont know about the single variable , ive always used object as variable container due to reference nature .


Excellent, third argument works :) thanks again!

The sad part of that even calling a task in the same thread doesn't works to get the correct patching_rect attribute :(

 method with some tiny delay value ? . i never tried to deal with comment label the way you do , it seems that setting text to it is low priority too . dont know how the order actually is provided .

damn , thats bad! .
can u try to use schedule method with some tiny delay value ? . i never tried to deal with comment label the way you do , it seems that setting text to it is low priority too . dont know how the order actually is provided .


This is really a nice discussion and and you can get more content from here :

Thanks JAVA SCRIPT...i neglected this topic (sorry for that) finally i didn't need the fix width for what i was doing.

I saw the link and it uses jquery library...is it available on Max? that would be really cool
