[Plplot-devel] Testing of latest qt pushes requested

[Alan W. I. <Ala...@gm...>]

Hi António:

I have just pushed your change and my subsequent followup to make the
initQtApp and close QtApp code easier to read and more robust.

Please look carefully at the code changes in my last commit
(plplot-5.14.0-15-g790754f35) and also test those changes to make sure
they work fine for your use case (qt applications using qt devices).

Unless you find something that needs changing with that last commit,
that should complete our joint qt development work until you have
a chance to work on PLplot again in a couple of months.

However, ideally it would be good to not have to wait that long for
the resolution of the occasional segfaults on exit for qt_example that
I encountered when comprehensive testing 5.14.0. So now that I
understand our qt device driver and binding a bit better, I am going
to look at that issue again.  And if I can find a simple fix, I will
commit that, but if I still cannot find such a simple fix (as happened
during the 5.14.0 release because I am still in the early stages of
learning C++ and Qt), I will leave that (more complex?) fix to you in
a couple of months.

Alan
