popup on click for a TableView itemDelegate

[caligoliv]

Lets have following QML code snippet:

@
Component {
Rectangle{
id: delegate
anchors.fill:parent
property var editableWidget;

    Text {
       anchors.fill:parent
        anchors.margins: 3
        anchors.centerIn: parent
        elide: Text.ElideRight
        wrapMode: Text.Wrap 
        text:  styleData.value 
        color: "black"
    }

    MouseArea{
        anchors.fill:parent
        onClicked: {
           editableWidget=Qt.createComponent("MyBigPopup.qml").createObject(delegate)
           // The widget is not displayed outside the item "delegate" even with a higher z-index to the  tableView
        }
    }
}

}
@

I would like to use a larger popup ( editableWidget) than the tableview cell.

The widget "editableWidget" is not displayed outside the item "delegate" even with a higher z-index than the tableView.

To place the item, I would like to use the system of anchors of the parent's widget.
I can of course attach the object directly to the tableView and use mapToItem but in this case, if the value of the scrollbar changed, the widget is not in the right place

Do you have a solution to see the entire popup with anchors system?

P.S.: Sorry if this is a duplicate. I didn’t find a similar thread.
