Please try run my qml and figure out what is wrong. I corrected code and it is still not working, it is as follow:
Qt Code: 
  1. import QtQuick 2.5
  2. import QtQuick.Window 2.2
  3. import QtQuick.Controls 1.4
  4.  
  5. Window {
  6.     visible: true
  7.     title: qsTr("Hello World")
  8.     visibility: Window.Maximized
  9.     Rectangle
  10.  
  11.     {
  12.         id: baza
  13.         x: 0
  14.         y: 0
  15. width: parent.width
  16. height: parent.height
  17.  
  18.         Rectangle
  19.         {
  20.             id: rect1
  21.             x: 0
  22.             y: 0
  23.             width: 9
  24.             height: 100
  25.             radius: width / 2
  26.             color: "blue"
  27.  
  28.             SequentialAnimation on y {
  29.             loops: Animation.Infinite
  30.             running: true
  31.             NumberAnimation { from: 0; to: { baza.height - rect1.heigh; } easing.type: Easing.OutExpo; duration: 3000 }
  32.             }
  33.         }
  34.  
  35.  
  36.  
  37.         MouseArea
  38.  
  39.         {
  40.  
  41.             anchors.fill: baza
  42.  
  43.             onClicked:
  44.  
  45.             {
  46.                 Qt.quit();
  47.  
  48.             }
  49.  
  50.         }
  51.  
  52.     }
  53. }
