This commit fixes a thinko in [8bab2338/lyxgit] causing the warning:
QObject::connect: No such slot lyx::frontend::GuiPreferences::slotApplyRC() in ../../../../src/frontends/qt4/GuiPrefs.cpp:3308
QObject::connect: (sender name: 'applyPB')
QObject::connect: (receiver name: 'PrefsUi')
This fixes the -geometry command line option and restores the
"Use icons from system's theme" checkbox in the preferences.
There is still code addressing Qt4 and xlib that has to be
audited. This code cannot be compiled with Qt5 because the
default backend is now xcb and not xlib. I have marked such
code with a "FIXME QT5" comment.
The listings package employs some dirty tricks internally, therefore it does
not work with utf8 encoding, but requires fixed width encodings. This version
of the fix uses ugly hardcoding instead of a layout file format change, so it
could be backported if needed.
This is needed since src/support calls lots of qt code, and some parts of it
(e.g. QFileInfo) require a running event loop. This fixes bug #4917 which is
a symptom of the problem.
The fix is to create a QCoreApplication for tex2lyx, lyxclient and LyX running
without GUI. In the future this could be extended, i.e. to split up the
frontend Application class in a GUI and a console class, and having the
console class use LyXConsoleApp in the same way as Application now uses
GuiApplication. If that is done, one could also think of moving
support/ConsoleApplication to frontend/console/ConsoleApplication.
* \caption does not need to be protected in general
* the contents of \caption arguments need to be protected, though.
All styles related to caoption inset have been audited and updated.
The special casing of captions in longtables has been removed, since there is no special case.
Fixes bug: #9177
This implement horizontal scrolling of rows to allow editing insets
(math, tabular...) that are larger then the screen. The scrolling happens
as the cursor moves, in order to make sure that the cursor is always visible.
This effectively closes an 11 years old bug.
This feature is the result of the work of Hashini Senaratne as part of
Google Summer of Code 2013. The code has been cleaned-up for inclusion
and remaining bugs have been fixed.
Fixes bug: #1083.
This resolves a dependency of src/support/docstream.cpp on src/TexRow.cpp,
which is the wrong way round. This fixes the linking
src/tests/check_ExternalTransforms with MSVC where the linker is not clever
enough to detect that the whole otexstream class is unused.
* When doing a redraw with drawing disabled (to set inset positions properly), take horizontal scroll offset in account
* reset horizontal scroll offset when it is smaller than the left margin.
* when drawing a paragraph, do not modify x globally, only for the row that is offset.
The new code should feel a bit more natural. It avoids explicit pixel values for the margins and does not scroll in some cases where it is not necessary.
[This commit is the output of the "horizontal scrolling" GSoC 2013
project, by Hashini Senaratne. The code has been cleaned up, some
variables have been renamed and moved from the Cursor class to
BufferView::Private. This is the base from which I (jmarc) will polish
the feature for landing on master.
Below is the original commit log of Hashini, updated to reflect the
changes that have been done.]
This feature also applicable for other insets; graphics and labels.
This implementation is capable of scrolling a single row when reaching
its content which is beyond the screen limits, using left and right
arrow keys.
The attribute 'horiz_scroll_offset_' introduced in the
BufferView::Private class plays a main role in horizontal scrolling of
the wide rows that grow beyond the screen limits. This attribute
represents by how much pixels the current row that the text cursor
lies in should be get scrolled.
The main logic that is responsible for drawing the scrolled rows is
within the BufferView class, BufferView::checkCursorScrollOffset.
* The main logic is called via BufferView::draw.
* What this does is set the horiz_scroll_offset_ attribute in in order to
show the position that the text cursor lies in.
* To make sure that BufferView::draw gets involved when Update flag is
FitCursor, necessary changes are made in BufferView::processUpdateFlags.
Basically what the logic that used to set the horiz_scroll_offset_
does is,
* The row which the text cursor lies in is identified by a
CursorSlice that points to the beginning of the row. This is the
'rowSlice' variable used in BufferView::checkCursorScrollOffset. Acessors
are added to obtain this variable. Here row objects were not used to
identify the current row, because it appears that row objects can
disappear when doing a decoration update for example. This means that
comparing row pointers is not a good idea, because they can change
without notice.
* Stop calculations of horiz_scroll_offset_ variable, if metrics have not been
computed yet. Otherwise the calls to TextMetrics::parMetrics, calls
redoParagraph and may change the row heigths. Therefore vertical scrolling
feature may get disturbed. This is avoided.
* Using BufferView::::setCurrentRowSlice resets horiz_scroll_offset_
when changing cursor row. This is done in order to prevent unwanted
scrolling that happens when changing the selected row using up and
down arrow keys.
* Recompute inset positions before checking scoll offset of the row, by
painting the row insets with drawing disabled. This is done because the
position of insets is computed within the drawing procedure.
* Current x position of the text cursor is compared with the
horiz_scroll_offset_ value and the other variables like row.width(),
bv.workWidth(). Compute the new horiz_scroll_offset_ value in order
to show where the text cursor lies in. The basics conditions that we
check before recomputing it are, if the text cursor lies rightward to
the current right screen boundary, if the text cursor lies leftward
to the current left screen boundary, if the text cursor lies within
screen boundaries but the length of the row is less than the left
boundary of the screen (this happens when we delete some content of
the row using delete key or backspace key).
* Change update strategy when scrooll offset has changed. This allows to
redraw the row when no drawing was scheduled. By doing so, it was
possible to redraw a wide row when moving to the leftmost position of the
wide row, from the leftmost position of the row below, using the left
arrow key.
In TextMetrics::drawParagraph it is checked whether the current row is
what is drawing now. If it is so, the value used to the x value of the row
for drawing is adapted according to BufferView::horizScrollOffset.
The method used to pass boundary() was fixed to get row when cursor was in
a nested inset. This matter is considered in Cursor::textRow and it is
modified accordingly.
GuiWorkArea::Private::showCursor() is modified to show the cursor position
in a scrolled row.
This happens when part of the word is selected.
To reproduce:
1. Start a new document
2. Type "af"
3. Select 'a'
4. Observe that the right part of the 'f' is clipped away.
This patch uses QRegion to set a clip region that is everything except
the part that is drawn in another color.
Fixes: #9223.
This is the first part of bug #8553. \textgreek was interpreted as the
polyglossia version even if polyglossia was not used. Now it is not recognized
at all and converted to ERT, but this ensures at least correct LaTeX output.
Actually I wanted to do that in cc87f8100 but forgot to adjust the original
solution completely. Now we do not search for an arbitrary latexkeys instance
which just happens to have the same name as the macro, but we only use the
symbol that was explicitly set for global macros.
Previously tex2lyx did ignore table columns if the column specifier was
unknown. This can lead to data loss, and now it does not ignore these columns,
but assumes that the column specifiers use only once character. This can still
lead to data loss, but less often.
If the user gave the -fixednec argument to tex2lyx then set that encoding as
LaTeX input encoding in the generated LyX file. Otherwise, included .bib files
could be interpreted using a wrong encoding.
It works with gcc >= 4.9.0 and clang (with libc++ or gcc libstdc++ from gcc
>= 4.9.0). The MSVC parg is missing, because I cannot test it, and the
autotools build still link against boost::regex even if it is not needed, but
I don't know how to fix that.
Now we can handle all types of captions defined in layout files or modules.
This does also mean that \captionabove and \captionbelow are only recognized
in KOMA-classes and not always anymore, but this is correct, since these
captions would not work in other document classes anyway.
As discussed on the list. We don't need it anymore, either we have a modern
compiler that supports C++11, or we fall back to boost. I kept and adjusted
the regex #define, since we cannot use std regex completely yet.
This fixes the tex2lyx test test-refstyle-theorems.tex. It seems that the
intent of the fix was to remove a \protect in front of a \caption,
\captionabove or \captionbelow, but the implementation did not really do that.
Furthermore, it is not clear in which cases a \protect in front of a caption
needs to removed, and in which cases it needs to be kept: After looking at the
LyX sources I could not see that caprions are always output with \protect.
All the code that is run before row metrics have been computed should use int arithmetic. After metrics have been computed, we still need doubles because fully justified rows use double for Row::Element::extra.
Rename Row::x to Row::left_margin and change its type to int.
Rename Row::Element::width() to full_width(). In some places of the code, use dim.wid (the int version without the extra separator) because metrics have not been computed.
Let Row::Element::x2pos take a int& argument instead of double&
Let Row::Element::breakAt take a int argument instead of double
This patch fixes a series of warnings like:

3 different strategies have been used:
* in frontend, some functions have been renamed.
* in InsetMath.h, Inset::write has been explicitly imported too
* in InsetMathNest.h, since a comment said that hiding Inset::metrics is intended, a special trick has bee used to silence the warning.
This is needed since all formats are stored in a global list which is shared
between threads, but never modfified except from the main thread.
The only missing bit is extension_list_, which is not so easy to do.
If we compile in C++11 mode, do not use the boost replacements for bind,
functional and shared_ptr. regex is excluded, since it misses match_partial, and
gcc does not provide a usable one in versions less than 4.9.0.
I also removed the #define for match_partial, since this is dangerous. Now you
get a compile error instead of subtle runtime differences.
The old detection did only work if CFLAGS contained -std=c++11, since ciso646
was only included for __cplusplus > 199711.
Thanks to Koernel for the cmake part.
Now all const methods may be called without additional locking.
This is assumed by the threaded LaTeX export, which always useses a globally
unique instance for each encoding.
Read-only access to these classes is now threadsafe, with one exception:
The encoding neds to be already initialized (i.e. init() must not be called).
This makes bug 9336 unreproducable on my machine, although it is not completely
fixed yet.
The interface is now 100% unit tested, and the typedefs depend on the new
STD_STRING_USES_COW configuration variable. The only missing bit is to detect
clang and disable STD_STRING_USES_COW for clang.
As discused on the list. This is not used yet, but it is intended to provide
thread-safe read-access without the need for synchronization if the used STL
implementation does not provide it for std::basic_string. This is the case for
all implementations using copy-on-write.
docstring is already defined in strfwd.h (which is included from docstring.h).
There are only two possible cases:
Either the typedef in docstring.h defines an identical type (then it is not
needed), or it defines a different type (then it generates a compilation error)
=> it is not needed.
The reason being that the TEXINPUTS path list was not quoted on Windows.
This was no problem with spaces but some special characters are
interpreted by the shell and can cause problems. In this particular
case, the '&' character was being interpreted as a command separator.
Thanks to Enrico, who noticed that the previous fix did not take into account
the case of nonempty length argument + the next line beginning with [.
Now the parsing is exactly the inverse of InsetMathGrid::eolString().
These are now in version.cpp. The build machinery should therefore make sure
that version.cpp is recompiled at every compilation.
These variables are now referred to by the other places that made use of __DATE__ and __TIME__.
This allows to address two main issues
* \thanks does only accept one paragraph, while \footnote allows several (ticket #2666)
* footnotes in titling environments were not numbered on screen.
Moreover, the code reduces hardcoding of features, which is always a good thing.
There are several pieces in this commit:
* new numbering type \fnsymbol for counters
* the Foot inset changes its layoutName() to Foot:InTitle when inside a paragraph with InTitle property. This is set when running updateBuffer.
* Foot:intitle uses the \thanks command, does not allow multiple paragraphs and marks its contents as moving argument.
* The InsetLayouts for Foot now have properLaTeXName/Type, so that InsetFoot::latex can be removed; further code simplification is probably possible.
Fixes: #2666
There was an unsymmetry between reading and writing: InsetMathGrid::eolString()
adds curly braces if the first cell of the next line starts with [ to prevent
misparsing as optional argument of \\. These braces were not removed on reading.
Some applications do not accept forward slashes, so call external viewers
and editors with backward slashes which is the usual convention under windows.
The many occurances of the mutable keyword in LyX sources make it quite
difficult to understand what is really const and what not, and to debug
multithreading memory problems. In this particular case it is not needed
at all to have a mutable member, so make it non-mutable.
The advantage is that the buffer will no longer be
marked as dirty when converting to the same type.
A quick break here is done instead of disabling the
LFUN because disabling the LFUN would lead to a greyed out
entry, which might confuse users. In the future, we might
want to have a radio button for switching between notes.
The assignment name = sub.str(1) reads from the first argument given to
regex_match(), but previously this was a temporary object which was already
out of scope. This did probably not matter much in practice, but invoked
undefined behaviour, and as we all know this is allowed ton format your hard
disk or kill to your cat, so better fix this.
One declaration of doExport() was not used, and the other one was only used by
Buffer, so make it private since returning the exported file name is a bit
strange if it can also appear as input argument.
This makes the script usable on windows and speeds it up by an order of
magnitude, since no new process needs to be forked for each layout file.
It also does not conevrt .old files again.
This is different from bug #8999, since in this case a new macro instance is
created. You still get a TeX capacity exceeded error if you try to typeset the
exported document, but this is the same as for bug #8999 and better than a
crash.
This is a patch I originally sent to lyx-devel in 2012 with subject
'Load footmisc.sty instead of using copied code from obsolete stblftnt.sty'.
It now takes all comments into account: It works also if the user loads the
package herself, it can be disabled by providing the footmisc feature in a
layout, and it does not use the ugly \AtBeginDocument{}.
The symptoms are the same as the original #9224, but the reason is different. In the new code, the width of justified rows includes the Row::separator value. Therefore the CRC computed in ParagrahMetrics::computeRowSignature is not updated in some cases.
The fix is to add Row::separator as one of the elements of the row crc.
Fix a crash reported in #7727. This happened because cur.pos() was reset before cur.pit(). In this case, cur.lastpos() will usually be wrong.
Fix bad behaviour when selecting at top level with several paragraphs.
Update documentation.
BufferParams::setDocumentClass() deletes the old document class of the buffer
and creates a copy of the new one. Therefore, the stored layout pointers in
the paragraphs (actually only one paragraph exists) are dangling afterwards.
Resetting them before setting the document class helps here.
In the long term we need to get rid of BufferParams::setDocumentClass()
completely, this is very ugly.
Invoking a computer algebra system program for computing a selected
subformula has never worked (checked with all LyX versions back to 1.3)
and, moreover, in the presence of a selection things go awry.
This commit allows this computation by replacing the selected
subformula with the result of the computation.
A similar fix was reverted (453ce611) because of crashes.
The crashes occurred simply because of a failed check that
we have a buffer view before using it. That is now done in
this commit.
The below commit description is copied from the original
commit (fb05011a):
Empty selections can cause confusing behavior for a few reasons:
(1) some functions behave differently depending on whether there is a
selection. If I press delete, nothing happens (where I expect the
character or inset before the cusor to be deleted). If I toggle bold or
emphasize nothing happens (where if there is no selection the entire
word is toggled). There are other LyX functions that depend on whether
there is a selection or not. Further, I wonder if any part of LyX's code
assumes that if there is a selection it is non-empty.
(2) menu options are incorrectly set. For example, the scissors icon.
For remaining empty selection issues, see #9222.
For more information, see:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg184758.html
Our TempFile class uses QTemporaryFile internally, and, on Windows,
this keeps the file locked so that we cannot rename it. So we have
to release the lock.
There are 3 possible actions (in order)
* select current cell
* select all calls of inset
* select the inset from outside (in the containing inset)
This fixes completely #7727.
The shape of the parbreak separator is slightly changed in order to
better distinguish it from the forced newline. This allows using the
same color of the plain version without risk of confusion.
The problem was that some parts of the code assume that the right margin is part of the width of the row. This is not the case, only the left margin (Row::x) is counted.
The code has been fixed and documented to reflect this.
Add display_pixel_ratio to buffer params to use it for displays with high resolution.
It holds the highest ratio between physical pixels and device-independent pixels of the LyX application.
Preview snippets will be generated using this value to get high resolution preview.
Add pixel_ratio to graphics params to use it for displays with high resolution.
It holds the ratio between physical pixels and device-independent pixels of the graphics.
Introduce the concept of pixel ratio: the ratio of physical and device independent pixels.
This is useful for rendering of content on Retina-displays of Mac hardware with high resolution.
Qt has real support for this starting with Qt5 - therefore it has to be compiled conditionally.
This change uses some work of Marcelo Galvão Póvoa, thank you.
What a selection spans several cells in mathed, and a deletion occurs though LFUN_CHAR_DELETE_FORWARD for example, only the case of a proper grid was handled. When no such grid exists, all cells between the first and the last index are cleared now.
If there is only one row, a new line should not be appended. If
there is more than one row, the new line should not be appended for
the last row.
For example, if in LyX there was "as you can see in $x$ there..." a
copy/paste would lead to a newline after "x".
lyxfind.cpp(findNextChange, findPreviousChange, findChange, selectChange): factor the change-selection part out of the change-finding part
Text.cpp (acceptOrRejectChanges): call only selectChange
