        implicitWidth: parent.width
        implicitHeight: parent.height
        clip: true

        model: ListModel {
            ListElement {
                description: "Wash the car this could be a really long message with some multiline support we will see how it works."
            }
            ListElement {
                description: "Fix the car"
            }

                description: "Sell the car"
            }
            ListElement {
                description: "Wash the car this could be a really long message with some multiline support we will see how it works. This should word wrap quite a lot of times."

                description: "Fix the car"
