QML: How to select a row in GridLayout


I want when I click or hover over a row in a GridLayout to change its background. How can I do this?

I tried to create a custom row for this action, but got stuck on the fact that I would have to create several such objects for each field (ComboBox, Label, TextInput, Button).

Here is my code for the resulting row:

Rectangle {
    id: root
    width: 200
    height: 20
    color: field.activeFocus ? "#a6a6a6" : (hovered ? "#c0c0c0" : "#eaeaea")
    property bool hovered: false

    MouseArea {
        anchors.fill: parent
        hoverEnabled: true
        onClicked: {
            field.forceActiveFocus()
        }
        onEntered: { hovered = true}
        onExited: { hovered = false}
    }

    GridLayout {
        anchors.fill: parent
        columns: 2
        Label
        {
            id: label
            Layout.row: 0
            Layout.column: 0
            text: "Unknown"
            Layout.minimumWidth: 80
            Layout.fillHeight: true
            Layout.fillWidth: true
            font.weight: field.activeFocus ? Font.Bold : Font.Normal

        }
        Label // ComboBox // TextInput // Button
        {
            id: field
            Layout.row: 0
            Layout.column: 1
            text: "Unknown"
            Layout.minimumWidth: 80
            Layout.minimumHeight: 20
            Layout.fillHeight: true
            Layout.fillWidth: true
        }
    }
}
