Is there a way to pass arguments to a ui object when it's created? (i.e. [myslider 450])

It looks like the _new routine for a ui object hijacks the normal use of arc and argv for a dictionary. Are arguments completely ignored, or can they be accessed in the _new routine as well?

Bumping up this thread. I am new to max and just started recently on building a custom external UI component using min. In the constructor I am getting an array of atoms. If I cout args[0], I get the word “dictionary” printed. I am however not able to figure out how to convert this atom into a usable dict object.

Bumping up this thread. I am new to max and just started recently on building a custom external UI component using min. In the constructor I am getting an array of atoms. If I cout << args[0], I get the word “dictionary” printed. I am however not able to figure out how to convert this atom into a usable dict object. I read somewhere else on this forum that UI objects use dictionary based constructors. Any examples of how to extract argument values in these? I have tried the object_dictionaryarg() method. As per documentation, this seems to be the method to be used with constructors using dictionary. I am however not sure how to use it in this context. Not sure how to pass the pointer to the first atom in the atoms array. object_dictionaryarg(args.size, args) or object_dictionaryarg(args.size, args[0]) does not compile.

Apologies if this is due to my basic misunderstanding of C/C++ pointers and objects.

args to UI objects can be passed as attributes, so make your args attributes.

Thanks for the reply. Strangely, even arguments does not seem to work. I have defined my argument as:

argument<int> defIndex_arg{ this, "Index", "Default key index to initialise this key",

cout << "in argument setter " << arg << endl;

This method is not triggered when passing arguments in the object box. I noticed 2 things:

I am not sure if it is relevant, but I went through the topic at

 I dont think the steps there are relevant to me as I could not trace out the folder names mentioned in that. Not sure what I am doing wrong.

I am working on Win10, MAX 8.2.1 and just cloned the min-dev repository today to ensure I have the latest.

Hello Rob,

Thanks for the reply. Strangely, even arguments does not seem to work. I have defined my argument as:

argument<int> defIndex_arg{ this, "Index", "Default key index to initialise this key",
        true,
        MIN_ARGUMENT_FUNCTION {
            cout << "in argument setter " << arg << endl;
        }
 }; 
 

This method is not triggered when passing arguments in the object box. I noticed 2 things: 

The argument name is NOT listed in the popup that displays all the arguments / attributes when we type them in the new object box

The argument gets listed properly in the reference view of the patcher window.

, this way users can provide a value using attribute syntax (@defIndex_arg 0) when creating the object.

Ok. attributes work. I have a bunch of other attributes I am already using. Thanks.

Is it then safe to assume UI OBjects don’t yet support arguments in min? Just frustrated as I spent quite a while trying to figure out what I was doing wrong.

My next battle is going to be with dict object.
