Get Repeater's child

[ixSci]

Kxyu, thanks for the answer!
No options to achieve it without wielding JS?
It is not that I 've something against JS. I just want to have a pure QML solution for this, if any.
There is no way to acquire children from the list, is there?

you can, actually I figured it out) i found the following string in Repeater description:
Items instantiated by the Repeater are inserted, in order, as children of the Repeater's parent

So you can access the children like this:

@import Qt 4.7

Rectangle {
id: screen
width: 1024
height: 600

Row{
id:container
Repeater{
model:3
delegate:Rectangle{
width:100
height:100
color:"red"
}

}
}

Component.onCompleted:container.children[1].color="black"

}
@

it works!

Kxyu, it is exactly what I've searched for. Thank you for the solution.
Though I don't understand why the parent item doesn't keep its children amount. Maybe it should? It seems a bit awkward to retrieve children from a Row and get children number from a Repeater :)

Nevertheless, the question is answered.

Well it keeps, as children is a List, and List does. But as far as I understand in QML it works like javascript array, so you can use it's length property. I don't know why, but it gives amount+1, still you can use it

Well the children array is 0-index. So 0 is the first child. However, a length property will be 1-index.
If you've already accounted for this, it could be that the 0th child is pre-populated (some hidden child?). I haven't tested this though.

Interesting property it should be documented I believe. Because I didn't find any mentions about it neither in documentation nor in the IntelliSense in QtCreator.

[ixSci]

Just tested it: a Repeater is the rightful child of an Item that is why you have amount + 1 result. If you exclude Repeater from the item you will have an actual amount.

IntelliSense needs some updates. It's not mentioned in documentation probably because it isn't related to QML. Just as the Math.functions aren't mentioned. Basically, javascript works in QML.

[ixSci]

But if the QML list is nothing more than JS list why there is not a single word about it? How can user find that he can use length property, for example, if he has no clue about a nature of a QML list?

well, that's correct, but I think it would be better, if list in QML had all QList members and worked the same way, not like javascript array
