can't create print object with object_new_typed
Hi.
I need to create a print object from within my external, and I’m trying to do it with object_new_typed.
What I found out is that if I try to instantiate it after a print has been created in a Max patch (because I typed it in, or because I have loaded a patch containing one) everything is fine. But if no print object has been instantiated before, then object_new_typed returns NULL.
I suspect this has to do with print being an internal object, and somehow its class not being correctly initialized by object_new_typed – I think I had already met this problem before…
… what can I do???
Thanks!

I just found this

in fact, instantiating my print object with newinstance() seems to work. I’m not sure this won’t generate problems, though… any advice?

Hi Tim.
Thank you for the link.
What I’m not sure of is why you need to instantiate the object with newinstance, then free it, and then re-instantiate it with object_new_typed. It is not that important, as long as things work ;) , but I’d like to understand more…
Thank you!

To be honest, I wrote that code 10 years ago and I don’t really remember why it is like that. I vaguely recall that I had to do that to make it work, but I was pretty inexperienced and wasn’t really sure what I was doing at that point. Sorry for the less-than-substantial answer on this one. At any rate, I do know that the code works and I haven’t had any problems with it.
