  }
  
  ListView {
       id: p1scores
       model: p1model
       delegate: delegate
       anchors.top: p1name.bottom

  }
  
  ListModel {
       id: p1model
       ListElement { score: "0" }
  }
  
  TextArea {
       id: p1input
       width: units.gu(8)
       height: units.gu(3)
       horizontalAlignment: TextEdit.AlignHCenter
       inputMethodHints: Qt.ImhDigitsOnly
       contentHeight: units.gu(60)

       width: units.gu(8)
       onClicked: {
          p1model.append({"score": p1input.text})
