Traversing like DOM

csgib

Hi,

First sorry for my english... i'm french and not very good in english.
I start learning QML and have a simple question :

Imagine a code like this :

@import QtQuick 2.2
import QtQuick.Window 2.1

Window {
id: mywindow

Rectangle{
    id: rect2
    x: 0
    y: 0
}

Rectangle{
    id: rect1
    x: 10
    y: 10
}

Rectangle{
    id: rect3
    x: 20
    y: 20
}

}
@

What i want, is make a function in qml (no c++ via qt) to traverse my window and get all the elements rectangle to get theire x and y positions.

Is it possible ?

Thanks

Stéphane

Hi,

Welcome to Qt Devnet.
You can use "data":http://qt-project.org/doc/qt-5/qml-qtquick-window-window.html#data-prop property to get list of visual childrens and then iterate over the list. Put this logic in a function and call it on Component.onCompleted. Something like
@
function getChilds() {
for(var a=0;a<mywindow.data.length;a++){
console.log(mywindow.data[a].x)
}
}
@

will print all x coordinates of the visual items.

P.S: Your english perfect and completely understandable :)

Hi and thanks....

But now a small complement to my first question....

Is there a solution to retrieve all the elements of a type like this in js/jquery :

$(".myclass").each(...

I understand the possibility with your answer but maybe there is a small hack to be more easy than scan everything just for extract an objectname (for example)

Well I'm not aware of any such inbuilt function but I guess that jquery should be doing the same internally.
