      Attached application simulates some heavy processing by using Sleep(1000) and it causes double valueChanged signal.

      Steps:
      -Build and run the example application
      -Press scrollbar to right once
      -Close the application and check the hit count(printed via qDebug)

      Actual result:
      -Hit count is 2

      Expected result:
      -Hit count is 1
