With Qt 5, our code did not correctly detect when icons were
available and thus tried to use nonexistent icons.
QIcon::hasThemeIcon(theme_icon) returns true when theme_icon is
empty. We now rely on the behavior that QIcon::isNull() returns true
if the icon is empty.
The same code is used with Qt 4 and Qt 5.
The old text was incorrect and came from the 2.0 release. LyX works fine if
the default python interpreter is python 3, as long as python 2 is available
as well.
Building LyX does also work with python 3, but since I did not check all
special build steps with both cmake and autotools, I kept a note about
possible problems.
This is used when scaling graphics previews. It is also used on a rare occasion
to scale instant previews when the user's configuration mixes low-dpi and
high-dpi monitors (#10114).
The aim of the tutorial is to explain how to use LyX and not special LaTeX issues with \frontmatter, non-TeX fonts etc. Therefore the preamble should kept clean.
With this change, it becomes possible to run the following commands:
inset-forall Separator:latexpar char-delete-forward
inset-forall Separator:parbreak inset-modify separator plain
The first one deletes all latexpar separators. The second one turns parbreak
separators into plain separators. This is safe, flexible, and avoids adding a
new LFUN.
We ensure that configure.py is called by python2, regardless whether 'python'
is python 2 or 3. Therefore we can simply call TeXFiles.py with the currently
running interpreter. This fixes configuration on systems where 'python' is
python 3.
Lyx files converted from 2.1 to 2.2 contain parbeak and latexpar separators that
would not appear if the lyx file was written in 2.2 from scratch. The script
removes latexpar separators and transforms parbreak separators into plain
separators. Then it displays a diff of the resulting pdf files (requires
diffpdf) for manual control. All lyx files shipped with lyx should be updated in
this way. See #10068.
example usage:
cd lib/doc
../development/tools/separator-convert.sh Math.lyx
The difference has been validated with diffpdf.
The following could not be tested and were left unchanged:
docbook_article.lyx
lilypond.lyx
linguistics.lyx
springer/sv*.lyx
de/linguistics.lyx
es/linguistics.lyx
ja/FeynmanDiagrams.lyx
ja/lilypond.lyx
ja/beamer.lyx
ja/xypic.lyx
The following is the script that I used (in lib/examples):
LYX=../../build/src/lyx
$LYX -E pdf2 $1.old.pdf $1
sed -i "s/^\\\\begin_inset Separator parbreak$/\\\\begin_inset Separator plain/" $1
sed -i "/^\\\\begin_inset Separator latexpar$/ { N; d; }" $1
$LYX -e lyx $1
$LYX -E pdf2 $1.pdf $1
diffpdf $1.old.pdf $1.pdf
The difference has been validated with diffpdf.
The following could not be tested and were left unchanged:
AEA.lyx
IJMPC.lyx
ja_beamer-conference-ornate-20min.lyx
The following is the script that I used (in lib/templates):
LYX=../../build/src/lyx
$LYX -E pdf2 $1.old.pdf $1

sed -i "/^\\\\begin_inset Separator latexpar$/ { N; d; }" $1
$LYX -e lyx $1
