Are the calls to qApp->flush() and processEvents necessary at all? I mean
today, maybe you inserted them some major versions back in time, and never tried
again without them after that.
I am porting from Qt 4.8.6 to 5.7 (2X)
I am porting from RHEL 5 to 6 (2X)
My app runs in an X11 environment where the users gets to choose her window
manager. (~3X)
They might be running through VNC or NX (2X)
I also run on Windows (+1)
(2 x 2 x 3 * 2) + 1 = 25.
Can anyone guarantee that I no longer need to call flush() and processEvents()
under all 25 conditions. Even if it tests out, we have seen there is a
certain degree of unpredictability. So, even if it works, I can not be sure why
it works.
FWIW: I just commented out flush(), processEvents() and it worked fine,
but I think it is just toying with me.
