you can try this:

focusscope{     height: 500;     width:500;     focus: true;     rectangle {         id:ex1         color:"red"         focus: ex1.visible;         visible:true;         anchors.fill: parent;         keys.onenterpressed: {             locktimer.restart();         }         keys.onreturnpressed:{             locktimer.restart();         }     }     rectangle {         id:ex2         color:"blue";         focus: !ex1.visible;         visible: !ex1.visible;         anchors.fill: parent;         keys.onreturnpressed:{             password.opacity=1;         }         text {             id: password;             anchors.centerin: parent             opacity: 0;             text: "enter password"         }     }  timer{     id:locktimer;     repeat: false;     ontriggered: {         ex2.visible=true;         ex1.visible=false;     } }  function settimer(val){     locktimer.interval=60000*val; }  component.oncompleted: {     settimer(2);     locktimer.start(); }
