QML TableView simple keyboard navigation

[preiter]

I'm trying to add some simple keyboard navigation to my QML TableView. What I want is:

• Tab makes the input focus move to the right (this one seems to just work out of the box)
• When the user hits Enter, after calling the onEditingFinished callback, move the input focus down one row (this one I can't figure out how to do)
• Ideally implement this in the properties of the TableView widget itself, because I would like to encapsulate this behavior into a custom component.

Any working examples out there? So far my research hasn't turned anything up.

Thanks for reading.

Found part of the answer...

            function updateFocus(row, column) {
                console.log("row " + row + " col " + column);
                if (row >= 0 && row < model.rowCount() && column >= 0 && column < model.columnCount()) {
                    var cellPoint = Qt.point(column, row);
                    datalogTableView.positionViewAtCell(cellPoint, TableView.Visible);
                    datalogTableView.itemAtCell(cellPoint).forceActiveFocus();
                }
                else console.log("skipped");
            }

This lets me set the focus at a given row/column coordinate. I can get the currently focused row/column from within the delegate. But I'm still searching for a way to get the row/column of the currently focused cell from the TableView widget itself.

import QtQuick
import Qt.labs.qmlmodels

Window {
    width: 640
    height: 480
    visible: true

    TableView {
        id: view
        anchors.fill: parent
        focus: true

        property Item currentItem: null

        model: TableModel {
            TableModelColumn { display: "a" }
            TableModelColumn { display: "b" }
            rows: [
                { "a": 1, "b": 2 },
                { "a": 3, "b": 4 }
            ]
        }

        Component.onCompleted: selectionModel.setCurrentIndex(model.index(0,0), ItemSelectionModel.Current)

        selectionModel: ItemSelectionModel {
            onCurrentChanged: (current, previous) => {
                                  var item = view.itemAtIndex(current);
                                  view.currentItem = item;
                                  item.focus = true;
            }
        }

        Rectangle {
            id: highlight
            color: "yellow"
            anchors.fill: view.currentItem ? view.currentItem : null
        }

        delegate: FocusScope {
            implicitHeight: 50
            implicitWidth: 50

            Keys.onReturnPressed: ti.focus = !ti.focus

            onFocusChanged: ti.focus = false

            TextInput {
                id: ti
                text: model.display

                onAccepted: {
                    var nextIndex = view.index((row + 1) % view.model.rowCount, column);
                    view.selectionModel.setCurrentIndex(nextIndex, ItemSelectionModel.Current)
                }
            }
        }
    }
}

I overlooked the portion of the request to separate the index change from the delegate. The current index can be pulled from the view's currentRow and currentColumn properties, or from the selection model. Eg view.selectionModel.currentIndex.row and view.selectionModel.currentIndex.column.
