Qt4.8 assigning a JavaScript function to a property

uroller

I want to pass a JavaScript function to a component through a property. It looks like this is possible in Qt 5.2 with the var type. Is there any solution for Qt 4.8?

I thought this was interesting. While you can't assign a function apparently, you can declare a function when use a component. So below, thing1 will use the somefunc declared in the Thing component. thing2 will use the custom somefunc declared when we declare thing2. Still can't find a better way.

main.qml:
@
import QtQuick 1.0

Item
{
Thing
{
id: thing1
}

Thing
{
    id: thing2;

    function somefunc()
    {
        console.log("custom func")
    }
}

}
@

Thing.qml:
@
import QtQuick 1.0

Item
{
function somefunc()
{
console.log("default")
}

Component.onCompleted:
{
    somefunc();
}

}
