    Description

      This is a regression against 6.7.

      With 6.8, emitting dataChanged on indexes does not cause the view to refresh.

      I have attached a small program to test this.

      The steps to reproduce are:

      • run the example
      • scroll a bit down
      • click the button (most of the time it works there)
      • scroll again a bit down
      • click the button

      The data is not refreshed unless you change the current row or scroll again.

       

      I just did a bisect and it is caused by
