Question

I want to switch focus from one field to the next when the user presses Enter: how would I go about it?

The items are arranged in a grid, as follows:

Answer 1

You can do so by using the Key attached property:

Grid {
    x: 5
    y: 3
    rows: 5
    columns: 20
    spacing: 10

    Repeater {
        id: rpt
        model: 50

        TextField {
            width: 28
            height: 50
            color: "green"
            text: "0000"
            font.pixelSize: 12

            Keys.onEnterPressed: rpt.itemAt(index + 1).focus = true

            validator: IntValidator {
                bottom: -256
                top: 256
            }
        }
    }
}
