Having trouble with the sfplay~ object, I would like to ask separately if there is any way to query my sfplay~ object the same way the playbar object seems to do it.

I cannot seem to intercept anything, so there must be some type of message or callback done in the background, in the Max SDK API. For example, perhaps something of the likes of object_method_typed() is used to query the time.

Can someone shed light on this?
Thanks a lot!

probably the same what is used by grab and attrui (and grab is oooold.)

(maybe even the same what is used to reject illegal connection attempts?)

Yes, but what is the exact symbol passed by object_method_typed()? ...or whatever grab or attrui use for that matter)?

Unless I am missing something obvious, I cannot see what type of message I could send to query the playback position of an sfplay~.

By "illegal connection attempts" you mean if the user intends to connect an integer only outlet to a bang only inlet?

It uses an internal API to achieve that. It used to use another strategy that you can still try for your own externs: your first extern A can send a symbol to the second extern B.

void yourextern_initconnection(t_object *x)

t_symbol *connect_sym = gensym("connect");

outlet_anything(x->out, connect_sym, 0, NULL);

void yoursecondextern_accept_connection(t_object *x, t_symbol *s)

if (s == gensym("connect") && s->s_thing != 0) {

// then you can call object_method* on x->connected_to

You'll probably want to set x->connected_to back to NULL, when object A disappear (so you probably need a disconnect called from object_free.

in extern A, you do something like :
void yourextern_initconnection(t_object *x)
{
    t_symbol *connect_sym = gensym("connect");
    connect_sym->s_thing = x;
    outlet_anything(x->out, connect_sym, 0, NULL);
}

and in your extern B:
void yoursecondextern_accept_connection(t_object *x, t_symbol *s)
{
    if (s == gensym("connect") && s->s_thing != 0) {
        x->connected_to = s->s_thing;
        // then you can call object_method* on x->connected_to
    }
}

thanks a lot! Is this internal API public, so that I could do my own extern to query the sfplay object?

Hi Emmanuel,

How does [playbar] query file position of an [sfplay~]?
