title: What is opposite of forceActiveFocus?
body: <p>I have these QML lines:</p>
  
  <pre><code>Item {
      id:container
      Rectangle {
          id:rec1
          width:20; height:20; x:20; y:20
          color:"blue"
          MouseArea {
              onClicked:rec1.forceActiveFocus();
          }
          //bla bla
      }
  
      Rectangle {
          id:rec2
          width:20; height:20; x:200; y:200
          color:"red"
          MouseArea {
              onClicked:rec2.forceActiveFocus();
          }
