@attribute questions

MIB

Hey everyone,

Another probably easy question for someone who knows how to read the docs... I just can't find the info I need or if I did find it, I don't know that I did :(

Ok, so I have an object for which I would like more than 1 @attribute.

I use the following to setup the args for the inspector:

CLASS_ATTR_LONG(c, "mode", 0, t_MRattrTest, mode);            //adds inspector support and attribute to object
    CLASS_ATTR_STYLE_LABEL(c, "mode", 0, "enumindex", "Mode");    //add text support to inspector
    CLASS_ATTR_ENUMINDEX(c, "mode", 0, ""int" "float"");    // text that is to be used in the inspector
    CLASS_ATTR_FILTER_CLIP(c, "mode", 0, 1);
    CLASS_ATTR_SAVE(c,"mode", 0);                                //if attribute is set in inspector and NOT typed into the object it is saved    

        CLASS_ATTR_LONG(c, "area", 0, t_MRattrTest, area);
    CLASS_ATTR_STYLE_LABEL(c, "area", 0, "enumindex", "Area");
    CLASS_ATTR_ENUMINDEX(c, "area", 0, ""Off" "On"");
    CLASS_ATTR_FILTER_CLIP(c, "area", 0, 1);
    CLASS_ATTR_SAVE(c,"area", 0);

In my _new(...) routine I then use attr_args_process(x, argc, argv);

That seems to work fine for the first attribute, but not the second or third (specially if the arguments are typed in in a different order than they were implemented). How do I implement several @-style attributes? Is there a convenience function or do I have to do it manually?
I thought maybe attr_args_offset() would be of help, but it only gives me the first instance of an @attribute and if arguments and @attributes are mixed that doesn't work anymore...

I did read the "Sending Messages, Calling Methods" part of the docs, but am none-the-wiser... where can I read up on this? any code examples I could study.

Thanks for any pointers!!

Hi vanille,

Thanks so much!! Yours works like a charm. I knew I was missing something simple. By the look of it, the only difference in your code to mine is that in my _new(...) routine I don't do this:

t_flop *x = NULL;

    if (x = (t_flop *)object_alloc (flop_class))
        {
            x->leftOutlet = bangout ((t_object *)x);

            attr_args_process (x, argc, argv);
        }

I allocate the object straight away... once I added the above code it works perfectly. THANKS!!
