It complicates stuff further down the line and we don't gain much for
it, so work with the rest of the stack rather than work around it.
One of the complications is that if bindir contains both plugins and executable, we will have okular and okular/ in the same folder and that doesn't really work.
We now definitely has std::as_const available and Qt has started nagging
about converting to std::as_const.
Implementation is the same for both functions, and qAsConst was a
stop-gap measure until std::as_const was sufficiently available.
In order to be able to also do this with Qt6 we can't currently rely on
'random distro' to be able to give us an environment sufficient for
running clang and clazy, so use the CI system setup instead
A side effect is that we get a newer clazy and clang-tidy and thus is a
few more issues to either ignore or fix.
Also, ask ninja to continue as long as possible rather than stop at
first error to be able to get succes in as few runs as possible
This bug would cause out-of-memory errors when zoomed in.
There's an equivalent (and therefore redundant) check for if the
normalizedRect is null, so it looks like the normalizedArea != 0 check
was an oversight, if anything.
QTime is quite inefficient and getFreeMemory sometimes gets called quite
frequently. I found that upwards of 10% of CPU time was being spent
inside of QTime in some cases. Besides being the recommended thing for
this use case, QDeadlineTimer is a lot more efficient.
This represents the newly entered data for each keystroke. This is often a single added character, but for cases like pasting text it can be more complex.
The PDF API reference doesn't specify any algorithm to use.
The algorithm used here works by iterating through both strings from the start until the first different character is encountered. Then the rest of the new text is considered the difference.
This doesn't produce the theoretically optimal/minimal diff, but seems to work well enough for practical application.
When text is removed the diff is empty
QLinkedList is deprecated in later Qt5 and gone in Qt6
The 1:1 port is std::list but in this cases all we ever do
is create the lists, push back to them, and pass then around
to be read, for that a QList is more than enough
Make it more similar to how we handle the format event.
We pass the new value to processKeystrokeAction, that calls the script
and sets the new value for the form object according to the result. If
needed the widget is refreshed to reflect the new text
