AMS align environment should have some spacing between odd and even columns.
Add a new virtual method displayColSpace() to InsetMathGrid, InsetMathHull and
InsetMathSplit.
A longstanding problem... (related: #1861)
The columns in AMS math environments have a fixed alignment (colAlign() in
InsetMathGrid.cpp). We set this alignment for display (Georg's
displayColAlign()) in InsetMathHull and InsetMathSplit. This is done according
to tests and documentation for the various environments.
There is also some mechanical code factoring via colAlign().
Finally, I disable setting the horizontal alignment in InsetMathSplit, which has
no impact on the LaTeX output, and has no longer any impact on the screen. (As
for vertical alignment I discovered that it was in fact customisable for
\aligned & friends! I hope that the more faithful interface will let other
users discover that too.)
The offending code appears to have been introduced a long time ago. My
understanding is that it is no longer relevant. Notably, it only appears on copy
and not on cut, which tells us that: 1) it should be safe to remove it, 2) we
should remove it for consistency.
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.
