Generate JS object with embedded context property generated from text?

fcarney

I have a set of context properties defined by another object. They are contiguous in their naming as xmBtn1 ... xmBtn6. I want to handle these in QML in a similar manner. How do I go about generating an object with a reference to these context properties without explicitly making a list of them: property var objs: [xmBtn1, xmBtn2, ... xmBtn6]?

I tried to generate a JSON object by parsing, but the object lacks context and fails to generate:

                    let buttons = []
                    for(let ind=0; ind<6; ++ind){
                        let str = "{button: %1}".arg("xmBtn%1".arg(ind+1))
                        console.log(str)
                        buttons.append(JSON.parse(str))
                    }

Output:

qml: {button: xmBtn1}
SyntaxError: JSON.parse: Parse error

Pretty sure JSON.parse doesn't know what to do with xmBtn1 as that is not in the context of the parse.

Is there a function in QML I can call that can retrieve a valid object to a symbol that is defined in the context?
Something like: Qt.getproperty("propertyname") ?

Did I just find the one legitimate use for eval?

let buttons = []
for(let ind=0; ind<6; ++ind){
    let obj = {button: eval("xmBtn%1".arg(ind+1))}
    console.log(JSON.stringify(obj))
    buttons.push(obj)
}
statusButtons = buttons
