Adding values to a variant holding map of key-value pairs

frankiefrank

I want to use the variant basic type http://doc.qt.nokia.com/4.7-snapshot/qml-variant.html in a dynamic way.
Meaning, rather than initializing it in the declaration

@
property variant attributes: { 'color': 'red', 'width': 100 }
@

I want to be able to initialize it with a string I split and parse later on.

Something like:

@attributes.add('opacity' : 1.0);@

What's the syntax for this?

Hi,

You could possibly do something like this:

@
QtObject {
property variant myobj

Component.onCompleted: {
    var myjsobj = {};
    myjsobj.blah = 6;
    myobj = myjsobj;
    console.log(myobj.blah)
}

}
@

As shown above, for QtQuick 1.x you'll probably need to use a JS var to dynamically create the object map, and then assign it to your variant property.

Alternatively, you could have a look at QDeclarativePropertyMap and see if it fits your needs.

Thanks. In this case I think I'm ok with just iterating through my list (it's not the classical property map usage) BUT I will definitely remember the QDeclarativePropertyMap for another time.
