Current code would change the color of static endlabel when the
_start_ of line is selected. This is only used with hollywood and
broadway layouts, though.
Change the box endlabel painting code to use Color_selectiontext as needed.
Follow-up to bug #10972.
This is preliminary work, this code still feels too complicated for
its own good.
Let Row::isMarginSelected return false when Row::selection() is false
(the other changes are indentation).
This allows to remove the test for selection() in
setSelectionAndMargins, so that begin/end_margin_sel are always set
correctly.
Add clearSelectionAndMargins() instead of calling directly setSelection
(which is now private) with arguments (-1, -1).
Fixes bug #10972.
A brand new event compressor based on Kuba Ober's cleverly simple
solution: <https://stackoverflow.com/a/21006207>.
Fix#9362, #9461, #9933: Lyx suddenly gets keyboard keys wrong, and
deadlocks
Fix#9790: LyX should perform key event compression (for improving the
remote X connections one would also need to implement
Qt::WA_KeyCompression)
Fix#10516: slowness on repeated arrow keys with IBus and Qt5

This fixes a regression in e64ea357, where a test has been (badly)
tightened to avoid that two consecutive rows may be redrawn to get rid
of caret ghosts. The test prohibited empty rows from being redrawn.
Moreover, improve the test of cursor boundary to avoid the case where
cursor position is already 0.
Fixes bug #10952.
A basic class like Length should not depend on something from
frontend.
This change allows to remove several dummy implementations of
theFontMetrics().
At some time it seemed like a good idea in breakRow() to return early
when the row was bound to be empty. It turns out that this creates two
symptoms:
* empty paragraphs will not have an end of paragraph marker
* since row width is not correctly computed in this case, caret ghosts
can appear in master.
This commit removes the oprimization and replace the do {} while()
construct to a straightforward while() {}.
Related to bug #10952.
It is not good for a support function to depend of anything outside of
it, especially Application.
Here the boolean that indicates that export should be canceled is put
in Systemcall. This allows to remove all the dummy theApp() function
that have been added here and there for linking needs.
Ligating of -- to en dashes occure also in teletype fonts.
With some 8-bit fonts, em and en dashes are not copied
exported from the PDF (but this is not limited to dashes in teletype).
With LatinModern, PDF export works fine
MWE:
\documentclass[]{article}
%\usepackage{lmodern}
\usepackage[T1]{fontenc}
\begin{document}
Hallo \texttt{Welt --Welt ---Welt}
Hallo Welt --Welt ---Welt
This gives a more consistent indication of what belongs to an environment
(and semantically, such paragraphs are synonymous to nested standard
paragraphs)
Addresses part of #9261.
VCS InsetInfos were broken by the switch at 2e934fc5f8 to using
updateBuffer to handle them. But we do not really want to go through
that routine in a clone, not for those insets, whose contents we
want to be the same as in the original Buffer.
Also fixes some issues noted in discussion of this bug: Failure to
update after context menu switch; failure to re-calculate shortcuts,
which can change.
This is complementary to AutoNests: Styles can determine which other
style should auto-nest them. This is particularly useful for modules
that add new styles which should be auto-nested in a given context.
Now layouts can specify other layouts that should be nested in and
after the current one (if the layout is switched from the current one
and if it follows a paragraph in the current one).
This is particularly useful for things such as the beamer frames, where
particular layouts are practically always nested.
These classes come with their own working implementation of table
footnotes, so we are not supposed to use the tablefootnote or
footnote package.
Also add missing outliner name.
This gets rid of the hardcoded latin1 encoding for verbatim. Instead,
verbatim now inherits the encoding from the context, which is what is
actually wanted here.
Fixes: #9012, #9258
While there is code in LyX that handles this, tex2lyx should respect
the format that LyX produces and the Flex: prefix is gone since
cfeddb92 in 2014.
In particular, this prefix is known to cause assertion when undoing a
document setting change.
This had the effect that for file dialogs supposed to use two buttons,
only the second one was displayed, while file dialogs supposed to use
one button did not have a button at all.
Candidate for 2.3.x and 2.2.x.
This spacing was wrongly removed at 361bd53b as part of the
introduction of proper spacing btween elements, but it only introduces
some breathing space around the delimiters. This will not be necessary
anymore when/if we use proper delimiters from the cmex10 font.
By default, inactive math corners are invisible. In practice they are
annoying because they are visible when selecting text, and they can
also overwrite some parts of the equation.
The code in Inset::drawMarkers2, which is only used for maths, is
moved to InsetMathHull. Moreover, the inactive corners are not drawn
when they have the same color as the math background. A better way to
achieve this would be to set the color to transparent, but we do not
support this yet.
Qt on macOS does not respect the Qt::WA_OpaquePaintEvent attribute and
clears the widget backing store at each update. Therefore, we use our
own backing store in this case.
This restores a simplified version of the code that was removed at 24c29908.
Now the helper class contains logic that checks whether buffer are
known before closing them. This avoids potential crashes.
Use it in different places to siplify code. It is not clear at this
point whether it should be used everywhere.
Followup to bug #10847.
When a buffer is in an embedded work area (adv. find&replace), it is
not found by BufferList:::exists(), and therefore the undo group
created in GuiApplication::dispatch and in the handling of
LFUN_COMMAND_SEQUENCE will not be closed.. Crashes can ensue, as
described in Ubuntu bug:
https://bugs.launchpad.net/bugs/1737429
The solution is to introduce BufferList::isInternal and act on it.
Fixes bug #10847.
This is a follow-up to 758de957.
- unify the metrics and drawing of \sqrt and \root using helper
functions mathed_root_metrics and mathed_draw_root.
- compute the vertical spacing above the nucleus of the root following
rule 11 of the TeXbook. In particular, it is different in inline and
display style.
- draw the root glyph without hard-coded pixel values. Make the line
width depend on the zoom.
more work is needed to implement properly rule 11:
- Ideally, we should use sqrt glyphs from the math fonts. Note that
then we would get rule thickness from there.
- The positioning of the root MathData is arbitrary. It should
follow the definition of \root...\of... in The Texbook in
Apprendix B page 360.
Fixes bug #10814.
It may happen that the buffers are visited in order buffer1,
buffer2, buffer1. In this case, we want to have only one undo group
in buffer1. The solution is to replace buffer_ with a set<Buffer*>.
A use case among others is InsetLabel::updateReferences.
The bug is the following: when selecting several paragraphs quickly
enough, some rows do not get selected.This is a consequence of the
removal of row crc, which lead to not taking into account the
selection status of the row in the decision to repaint.
The solution chosen here is to add a Row::change() helper function to
modify row members. This will set the Row changed status whenever the
value of the member changes.
