Drag and Drop in ListView - qt

Question

I am trying to drag and drop a ListView row and I am having trouble at the drag stage. Below code doesn't drag anything and name column is not aligned properly. I don't want to specify a size for ListView and I want it to get its size from its content Row with id row. It should be able to because text has size coming from its font size and Rectangle has set width. ListView can get wider as needed to show the name part.
import QtQuick 2.11
import QtQuick.Layouts 1.11
ListView {
id: root
height: scrollview.viewport.height
model: listModel
delegate: dragDelegate
Component {
id: dragDelegate
MouseArea {
id: dragArea
anchors { left: parent.left; right: parent.right }
height: content.height
drag.target: pressed ? content : undefined
drag.axis: Drag.XAndYAxis
Rectangle {
id: content
anchors {
horizontalCenter: parent.horizontalCenter
verticalCenter: parent.verticalCenter
}
height: row.implicitHeight
border.width: 1
border.color: "lightsteelblue"
color: "green"
radius: 2
states: State {
when: dragArea.pressed
ParentChange { target: content; parent: root }
AnchorChanges {
target: content
anchors { horizontalCenter: undefined; verticalCenter: undefined }
}
}
Row {
id: row
Text {
text: name
font.pointSize: 15
}
Rectangle {
height: parent.height
width: 40
color: hexColor
}
}
}
}
}
ListModel {
id: listModel
ListElement {
name: "first-name"
hexColor: "red"
}
ListElement {
name: "second-name"
hexColor: "green"
}
}
}
