Qt Parsing and comparing the value in qt - json

Question

I have json format like this->
{
"id": 7,
"sort_decs": "Identity",
"last_name": "Lawson",
},
{
"id": 8,
"sort_decs": "Identity",
"last_name": "Ferguson",
},
{
"id": 9,
"sort_decs": "Identity",
"last_name": "Funke",
},
{
"id": 10,
"sort_decs": "Identity",
"last_name": "Fields",
},
{
"id": 11,
"sort_decs": "Identity",
"last_name": "Edwards",
}
In qtreewidget how can I get sort_desc value for parent1 and last_name in its childs. if the sort_decs value is repeated how can get it only once in parent1 and last_name 's in childs .
I am gettting if the sort_decs value is == "Identity" manually.

You may not even need to use TreeView. If I understand your data correctly you could use a ListView with section.property: "sort_decs":
import QtQuick
import QtQuick.Controls
Page {
ListView {
id: listview
anchors.fill: parent
model: [
{ "id": 1, "sort_decs": "Griffindor", "last_name": "Potter", },
{ "id": 2, "sort_decs": "Griffindor", "last_name": "Weasley", },
{ "id": 3, "sort_decs": "Griffindor", "last_name": "Granger", },
{ "id": 4, "sort_decs": "Slytherin", "last_name": "Malfoy", },
{ "id": 5, "sort_decs": "Slytherin", "last_name": "Crabbe", },
{ "id": 6, "sort_decs": "Slytherin", "last_name": "Goyle", },
{ "id": 7, "sort_decs": "Identity", "last_name": "Lawson", },
{ "id": 8, "sort_decs": "Identity", "last_name": "Ferguson", },
{ "id": 9, "sort_decs": "Identity", "last_name": "Funke", },
{ "id": 10, "sort_decs": "Identity", "last_name": "Fields", },
{ "id": 11, "sort_decs": "Identity", "last_name": "Edwards", }
]
delegate: ItemDelegate {
width: ListView.view.width - 20
background: Item { }
text: modelData.last_name
padding: 0
icon.source: "Tree.svg"
}
section.property: "sort_decs"
section.criteria: ViewSection.FullString
section.delegate: ItemDelegate {
//width: ListView.view.width - 20
padding: 2
background: Rectangle { border.color: "#888" }
text: section; font.pointSize: 14
}
ScrollBar.vertical: ScrollBar {
width: 20
policy: ScrollBar.AlwaysOn
}
}
}
// Tree.svg
<svg width="32" height="32">
<path d="M16 0 16 32 M16 16 32 16" stroke="black" fill="none"/>
</svg>
