[SOLVED] Dynamic instance of Binding Component on array element. Issue.

billouparis

Hello,

I am stuck with an easy one:

*import QtQuick 2.2

Item {
id: idMain
Component {
id: bindingComponent
Binding {

    }
}

property variant list1: ["A", "B", "C", "D", "E"]
property variant list2: ["a", "b", "c", "d", "e"]
property variant list3: list1

Item {
    id: myRepeater
    Repeater {
        model: 5
        Text {
            property alias idText: idText
            id: idText
            text: index
        }
    }

}

property variant objKeyBinding: []
function fnCreateBindings()
{
    var i = 0
    for (i = 0; i < 5; i++)
    {
        objKeyBinding[i] = bindingComponent.createObject( )

        objKeyBinding[i].target = myRepeater.children[i].idText
        objKeyBinding[i].property = "text"
        objKeyBinding[i].value = list3[i]

    }
}

property bool bbool: false
Timer {
    interval: 1000
    repeat: true
    running: true
    onTriggered: {
        if (bbool === true)
        {
            list3 = list1
            console.log("if "+myRepeater.children[0].idText.text)
        }
        else
        {
            list3 = list2
            console.log("else "+myRepeater.children[0].idText.text)
        }
        bbool = ! bbool
    }
}

Component.onCompleted: {
    fnCreateBindings()
}

}

The console output of this code leads to
qml: else A
qml: if A
qml: else A
qml: if A

And I am expecting:
qml: else a
qml: if A
qml: else a
qml: if A

What can I do to have an actual dynamic binding working there?

One colleague found a solution:

objKeyBinding[i].value = Qt.binding(function(){return list3[this]}.bind(i))

That's crazy!
