Repeater bug?

Hello I have the following basic code:
@import QtQuick 2.0
import QtGraphicalEffects 1.0Item {
id: idRoot
width:800
height:480property real nbrOfOccurences: 10 Item { id: idItem1 Repeater { id: idImagesRepeater model: nbrOfOccurences Image { id: idImage source: "someimage.png" x: Math.ceil(Math.random() * 650) y: Math.ceil(Math.random() * 350) visible: true } } Repeater { model: nbrOfOccurences ColorOverlay { source: idItem1.children[index] anchors.fill: idItem1.children[index] color: Qt.rgba(Math.random(),Math.random(),Math.random()) visible: true } } visible: true }
}
@> i know that source image shall be set to false, I set them to true intentionally.
> running this code, I see 9 images on which a ColorOverlay is applied, and the first image does not have the ColorOverlay effect applied. Anyone can spot my error, or is it a repeater error?

The following code seems to be OK, But I still want to understand what is wrong with the original proposition in the first post?
And yes, I know that source image shall be set to false, I set them to true intentionally.@ import QtQuick 2.0
import QtGraphicalEffects 1.0Item { id: idRoot width:800 height:480 property real nbrOfOccurences: 10 Repeater { id: idImagesRepeater model: nbrOfOccurences Item { id: idItem1 Image { id: idImage source: "someimage.png" x: Math.ceil(Math.random() * 650) y: Math.ceil(Math.random() * 350) visible: true } ColorOverlay { source: idImage anchors.fill: idImage color: Qt.rgba(Math.random(),Math.random(),Math.random()) visible: true } visible: true } } }

Hi,
I guess that would be because the idItem1's first child would be a Repeater. Your second approach is actually the right way to do it.

Hello,
actually I printed out the children and the images are the first children indeed, the repeater is coming after the images in the children list.
The first proposal works fine for the 9 following images, it only fails for the first one. I still would like to understand why? Is there a Qt bug or not?Bill

Try printing it in ColorOverlay since at that point only the First Repeaters Items are popluated.
@
ColorOverlay {
Component.onCompleted: console.log(idItem1.children[index])
}
@

I made additional tests, and the weird thing is the following:
 if I spot the children changes, the result is not the same as when the component has completed. Why?
@import QtQuick 2.0
import QtGraphicalEffects 1.0
Item {
id: idRoot
width:800
height:480property real nbrOfOccurences: 2 Item { id: idItem1 Repeater { id: idImagesRepeater model: nbrOfOccurences Item { id: idImage width: 100 height: width x: width*index } } Repeater { model: nbrOfOccurences ColorOverlay { source: idItem1.children[index] onSourceChanged: { print ("source for index "+index+" is "+source) } } } onChildrenChanged: { print ("children Changed ") var i=0 for (;i< 10;i++) { print("idItem1.children[ "+i+"] "+idItem1.children[i] ) } } } Component.onCompleted: { print ("Component on Completed ") var i=0 for (;i< 10;i++) { print("idItem1.children[ "+i+"] "+idItem1.children[i] ) } }
}
