Hi Nicolas,

in fact i wanted to hide/show the bpatcher object itself. In consequence, the bpatcher's content is also hidden/shown. It works perfectly for normal max objects. But if the obejct is a bpatcher, then it doesn't work

Here is some more code:

long getnamed_maxbox_iteration(t_myobject *x, t_object *box) { t_symbol *foundname = object_attr_getsym(box, gensym("varname")); if (!strcmp(foundname->s_name,x->findstring)) { x->found_maxbox = box; return 0; } return 0; }

t_object *getnamed_maxbox(t_myobject *x, t_object *obj, char *findstring) { long result = 0; x->found_maxbox=NULL; strcpy(x->findstring,findstring); object_method(obj, gensym("iterate"), (method)getnamed_maxbox_iteration, x, PI_WANTBOX, &result); if (x->found_maxbox) { return(jbox_get_object(x->found_maxbox)); } }

and then somewhere i execute

t_object *voice_parameters = getnamed_maxbox(x,x->orchestra_patcher,varname ); jbox_set_hidden(voice_parameters ,offon); //max bug: doesn't work for bpatchers

Thanks Thomas

Hi Nicolas,

thank you very much, it works now. For bpatchers and patcher, i had to use

return(x->found_maxbox);

instead of

return(jbox_get_object(x->found_maxbox));
