How would I use the arrow keys to move rectangle?

Qt Code: 
  1. Rectangle {
  2.         id:point
  3.         anchors.centerIn: parent
  4.         width: 20
  5.         height: 20
  6.  
  7.         opacity: 0.2
  8.  
  9.         MouseArea {
  10.             anchors.fill: parent
  11.             drag.target: root
  12.             onPositionChanged: {
  13.                 if(drag.active) {
  14.                     dragged()
  15.                 }
  16.             }           
  17.         }
  18.         Keys.onPressed: {
  19.                if (event.key == Qt.Key_Left) {
  20.                     console.log("move left");
  21.                     event.accepted = true;
  22.                     point.x-=1;
  23.                 }
  24.             }
  25.     }
