how to use intload()

Mar 22 2013 | 11:54 pm


I’d like to know how I can use intload to create a toplevel-patcher with arguments.
The problem is that I don’t really understand the method signature.

void *intload(C74_CONST char *name, short volume, t_symbol *s, short ac, t_atom *av, short couldedit);

I tried:

short couldedit = 0;
    t_atom *av[9];
    atom_setlong(av[0], 0);
    atom_setlong(av[1], 0);
    atom_setlong(av[2], 0);
    atom_setlong(av[3], 0);
    atom_setlong(av[4], 0);
    atom_setlong(av[5], 0);
    atom_setlong(av[6], 0);
    atom_setlong(av[7], 0);
    atom_setlong(av[8], 0);

    t_object* opened_patch = intload("my_patcher", 1, gensym(""), 9, av, couldedit);

I don’t understand what the volume is (or how to get it) and what symbol is expected.

thanks Nicolas, that code example was quite helpful!

Now I’m able to create the patcher with arguments
but somehow if I use intload, fileload or jpatcher_load
there’s no patcherview created(and no max window opened) for the patcher I specified with the string.

But subpatches contained in the opened top-level-patcher appear
(when the top-level patcher was saved with open subpatchers) with a window and are having correct arguments.

Here’s the code:

/*–––––––––––works correctly––––––––––––––––*/
    char filename[MAX_FILENAME_CHARS];
    strncpy_zero(filename,"new.maxpat", MAX_FILENAME_CHARS);

    t_uint32  type_searched_for = 'JSON';
    t_uint32  type_found;

    short path_id = 0;
    int res = locatefile_extended(filename,&path_id, &type_found ,&type_searched_for, 1);

    if(res == 0 && path_id != 0)    {post("filename found");}
    else if(res != 0)               {post("filename not found"); return;}

    short couldedit = 0;
    t_atom av[9];
    atom_setlong(&av[0], 99); //#1
    atom_setsym(&av[1], gensym("aaa")); //#2
    atom_setlong(&av[2], 0); //#3
    atom_setlong(&av[3], 0);
    atom_setlong(&av[4], 0);
    atom_setlong(&av[5], 0);
    atom_setlong(&av[6], 0);
    atom_setlong(&av[7], 0);
    atom_setlong(&av[8], 0);

    t_object* opened_patch = NULL;
    opened_patch = intload("new.maxpat", path_id, NULL, 9, av, couldedit);
//    opened_patch = jpatcher_load("new.maxpat", path_id, 9, av);

    if(opened_patch != NULL)
        {post("opened_patch found adress is %i", opened_patch);}
    else if(opened_patch == NULL)
        {post("opened_patch not found : %i", opened_patch);return;}

    t_object* open_p_topview = NULL;
    open_p_topview = jpatcher_get_firstview(opened_patch);

    if(open_p_topview != NULL)
        {post("open_p_topview found adress is %i", open_p_topview);}
    else if(open_p_topview == NULL)
        {post("open_p_topview not found : %i", open_p_topview);}

While everything else is found, the last branch states "open_p_topview not found".
jpatcher_get_firstview(opened_patch) returns NULL. (If intload, fileload or jpatcher_load was used)
From what is documented in the headers at least fileload should open a window what it doesn’t.

…maybe someone from cycling can give me a hand on this…?

…hopefully not

Best case would be if someone could explain it with: jpatcher_load_fromdictionary
I’d like to do like this:

//...code like above

t_dictionary *rd;
rd = dictionary_sprintf("@hidden 1"); // to hide the patcher when opened
opened_patch = jpatcher_load_fromdictionary("empty_track.maxpat", path_id, rd, 9, av);

Without having the slightest experience with patcher window management, I am convinced that anything that has jpatcher in its name is definitely not Max 4-related. As far as I remember, JUCE was introduced in Max 5.

Hope that helps,

good to know, this gives some hope, thanks!
