[Solved] Iterate through children of a QML Item ?

[serdef]

Hi,

i am trying to extend a qml item (in this case a flickable) with a method that logs a property of its children.
It seems not to work, when I click, the function is executed but I get only one item and it is not one of the children.

Application Output :
qml: item 0
qml: undefined
from the code below:

@
import QtQuick 2.2

..... some qml items.....

Flickable {
    id: flicktest
    x:0
    y:0
    width: 100
    height: 100
    contentWidth: 200
    contentHeight: 200
    function logallitems()
    {
        for (var i = 0; i < children.length; i++)
        {
            console.log("item "+i);
            console.log(children[i].propname);
        }
    }
    Text{
        id: dummy1
        x: 10
        y: 10
        property string propname :"hey1"
        text: propname + " !!"            
    }
    Text{
        id: dummy2
        x: 10
        y: 30
        property string propname :"hey2"
        text: propname + " !!"            
    }
    Text{
        id: dummy3
        x: 10
        y: 50
        property string propname :"hey3"
        text: propname + " !!"          
    }
    MouseArea{
        anchors.fill: parent
        onClicked: { flicktest.logallitems() ;}
    }
}

.... other items

Does any of you experts know how to do this the right way ?

Hi,

Try this:
@
function logallitems()
{
for (var i = 0; i < flicktest.contentItem.children.length; i++)
{
console.log("item "+i);
console.log(flicktest.contentItem.children[i].propname);
}
}

You are Welcome :)
contentItem works because all the items in Flickable are actually childrens of it.

Thanks for explaining, now I also understand why, what a luxury !!
