I'm having a bit of a brain fart here. I have a third-party class I'd like to
use that inherits from QAbstractScrollArea. Qt Designer only knows about a
QScrollArea, though, which inherits QAbstractScrollArea.
How do I use this as a concrete Qt class

You're off by one year. 5.9.0 was released May 29, 2017.
5.9's support ends in May 2019 (probably a bit later because we are able to

The reality is that if your software depends on multiple libraries, your
deadline is the whichever EOL for those libraries

I understand LibreSSL has some advantages, is that worth checking out?
Qt does not work with LibreSSL.

I just learned that Qt 5.9 apparently doesn't build against OpenSSL 1.1 . Does
anyone already have a fix for this?
Which distribution already stopped shipping OpenSSL 1.0?

The problem is not the GCC version. It's the set of libraries provided by
the old distribution.
And I guess he could still build his own packages. The libraries would just
use bundled qt copies if too old. Only the prebuilt packages have

When you use a layout, you do not need to pass a parent when constructing the

QWidget::setParent()) so that they are children of the widget on which the
layout is installed.

I am not 100% sure, it's been a while, but I would assume that the layout is

So... after a full day of debugging, trying to port my Qt4 app to Qt5

Thank you Nils. My question may have have been incomplete. I am looking
