[REG 4.8.6->5.0.0] QScrollBar emits valueChanged twice if slot takes too much time

XMLWordPrintable

    • 1c1cce67fa1d03a49cdfb6f1ca378b182925ffdb

      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
