Good places for variables when using matrix

Hi

I use the "ultimate custom module" for Cubase in order to dynamically get articulations names.

The matrix i use to get those articulations is set this way in the CM :

ConstruisTaMap().then(cequilmefaut => {
      
        receive('/EDIT', 'matrix_articulations', {'props': `JS{
                var props={}
                let Index=parseInt($)+1
                props.id="b"+Index
         ...
                var labs = ${JSON.stringify(mesArticulations)} 
                var max = labs.length
                props.label= labs[$]
                props.visible = Index <= max                                                   

                props.onCreate = max <= 4 ? "setVar('parent','GT',1)" : "setVar('parent','GT',2)"

                props.address="/note"
                props.preArgs=[1,$]
                props.target="midi:KSCC"
                return props
                }`})

So, the props.onCreate line is used to change the matrix gridTemplate property, using VAR{GT}.
It works :
grid

But, i have this in the console :

So... is the way i set the matrix gridTemplate ok ? I may be still confused on how it works, but if i'm right, here props.onCreate will set the GT variable 50 times if i do have 50 buttons... so... is there a better place / way to set the whole thing ?

Thank you

It doesn't really make sense to set gridTemplate this way, you could simply modify it with the /EDIT command:

var GT = 2 // compute grid template here
receive('/EDIT', 'id', {props: 'JS{...}', gridTemplate: GT}

As for the error, you fell in one of the advanced syntaxes limitations:

  • container widgets can inherit their children's properties only to define dynamic properties

The documentation however doesn't make it very clear that it applies not only to the @{} syntax.

Ok, thank you.

As GT depends on other variables, I finally found that i had to set GT up in the async function definition to get the whole thing working. That's what i was looking for :slight_smile:
