How do I access the children of a repeater object in a function?

[dxmachina]

Hi Guys,

Apologize for the newbie-question. I have some text objects in a repeater like this:

Item {
	id: artText
	Repeater {
		id: artTextRepeater
		model: 12

		Text {
			height: 56
			width: 100
			color: "black"
			visible: index > 0 ? false : true
			text: "Hello " + index
			//x: mouse.x
			y: layerA.y + 22
			x: 100

		}
	}
}

I want to be able to change the assigned text of all items in a function. I've tried both of these, but no luck:

function adjustText(){
	for (i = 0; i < 12; i++) { 
		artTextRepeater.itemAt(i).text = "New Text"
	}
}

function adjustText2(){
	for (i = 0; i < 12; i++) { 
		artTextRepeater.children[i].text = "New Text"
	}
}

Sorry if this is really obvious! Thanks for the help.

@dxmachina Don't you need to write var i = 0 in your for loop?

I've been working with your code and I think is correct. Here you have my code:

import QtQuick 2.5
import QtQuick.Window 2.2

Window {
    visible: true

    Item {
        id: artText
        Column {
            Repeater {
                id: artTextRepeater
                model: 12

                Text {
                    height: 56
                    width: 100
                    color: "black"
                    visible: true
                    text: "Hello " + index
                }
            }
        }
    }

    Rectangle {
        id: rect
        x: 100
        y: 100
        width: 100
        height: 100
        color: 'blue'
        MouseArea {
            anchors.fill: parent
            onClicked: { adjustText(artTextRepeater)  }
        }
    }

    function adjustText(element) {
        for (var i = 0; i < 12; i++) {
            element.itemAt(i).text = "New Text"
        }
    }
}

Welcome @dxmachina , Yes you need to define the "var type for i variable in for loop ".
Addition to above answer I will suggest below snippet where you can get rid of hard coding for model count in function

function adjustText(repeaterItem) {
for (var i = 0; i < repeaterItem.count; i++) {
if(repeaterItem.itemAt(i).text === ("Hello"+ i))
{
repeaterItem.itemAt(i).text = "New Text"
}
else{
repeaterItem.itemAt(i).text = "Hello"+ i
}

    }
}

Timer{
    id: timer
    interval: 1000
    running: true
    repeat:true
    onTriggered: {
        root.adjustText(artTextRepeater)
    }
}

Thanks

Thanks very much, guys. Of course you are 100% correct. Whoops... even more newbish than I feared!

@dxmachina Well, that's not true ;) Just a little mistake. Happy coding! :D
