How to read a property of a QtObject in list

[johngod]

I have something like:

property var listGraphs: []
QtObject {
        id: graph
        property string xmin: "-20"
        property string xmax: "20"
        property string zmin: "-20"
        property string zmax: "20"
}
--------
listGraphs.push(graph)
--------
listGraphs[0].xmin // error undefined

What should be the correct sintax in the last line to read the properties of the QtObject ?

import QtQuick 2.12
import QtQuick.Window 2.12

Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")

property var listGraphs: []
QtObject {
        id: graph
        property string xmin: "-20"
        property string xmax: "20"
        property string zmin: "-20"
        property string zmax: "20"
}

Component.onCompleted: {
    listGraphs.push(graph)

   console.log( listGraphs[0].xmin)
}

}

@johngod you should put the last 2 statements in a function and call it.you are using the syntax of a property for a function which is wrong

@Ronel_qtmaster I did that, the code I posted was cutted for simplicity. Either way it started to work, maybe it just needed some qmake clean up. Thanks.
