* GuiFontMetrics::pos2x, x2pos: add support for inter-word spacing.
* GuiPainter::text: idem
* Row::Element::countSeparators:
Row::countSeparators: new methods that count spaces in strings.
Row::setSeparatorExtraWidth: new method (code lifted from TextMetrics.cpp).
* TextMetrics::computeRowMetrics: rely on the above methods.
* RowPainter::paintMispelledMarked: pass only a Row::Element object reference
RowPainter::paintStringAndSel: idem; do not rely on values returned by
Painter::text (trailing spaces do not honor wordspacing value).
The goal of this commit is to make painting faster by reducing the
number of strings to paint. To this end, it is necessary to include
spaces in row elements.
Also importantly, this commit should fix existing problems with line
breaking in chinese text.
* TextMetrics::breakRow: do not do anything special for word separators.
* Row::add: when adding a character to a row element, keep the string
width updated. If need be, it is possible to tweak this by updating
every 10 characters, for example.
* GuiFontMetrics::breakAt (new): use QTextLayout to break text either
at word boundary or at an arbitrary width.
* Row::Element::breakAt: use the above method.
* Row::shortenIfNeeded: simplify now that because there is no need for
handling separator elements. This will be taken care of by the
improved breakAt.
Two things remain to be done:
* remove all traces of separator row element
* re-implement text justification.
When adding units to the external inset bounding box I overlooked that
InsetGraphics supports only bb, cm, mm and in. Therefore I added too many
units for the external insets. We are not as strict as the graphics inset
and allow all absolute units, but no relative ones.
This brings the external inset on par with the graphics insets as far as the
clipping option is concerned. The graphicxs package supports both: A bounding
box without units (which means that bp ia assumed), and a bounding box with
units, so we can simply output the values including the units.
Being able to compile document with zipped .eps files was a useful feature of
the graphicxs package 20 years ago, but the LyX support is no longer relevant:
- The flag is ignored if preview is on
- If pdflatex is used then uncompressing happens during the compilation anyway
- If set, the flag prevents LyX from issuing proper error messages if
something with the image is wrong
- For hard disk capacities from 20 years ago not uncompressing is a useful
feature, but for current hard disk capacities it does not matter
- The external inset does not have it, and if we want to merge both insets
one day we would need to implement it there, which is even more difficult
than in InsetGraphics
Since commit 7ac70092, lyx::dispatch returns a DispatchResult const &,
which is ignored in the cases below. Nevertheless, the windows
compiler complains that it does not know this type. Gcc and clang can
deal with it without problem.
Now the minibuffer toolbar is "auto" by default. It is opened by
command-execute (M-x) and closed when the command is executed without error.
* make lyx::dispatch return a DispatchResult struct
* there is a new MINIBUFFER type of toolbar, that can be used for this use.
* remove special handling of M-x in minnibuffer; Escape can be used instead. Fix focus in this case.
* when minibuffer toolbar is "auto", make the toolbar close itself after
- a command has been executed without error
- an empty command has been executed
- the Escape key has been used
[this is actually commit fdcff02a, which was later reverted at dd61d8cf]
There is a second solution in the code which uses some undocumented Qt
stuff, but it does not work in some cases. The best is to rely on the
documented way.
There is no need for real-valued line width in painters. Actually, this even leads to uneven dashes for continuous spell checker.
The new code is supposed to be equivalent to the old one, just more readable. From this, we can try to see whether some lines need to be made thicker on HiDPI screens.
This effectively makes the horizontal size policy "minimum", which
makes it clear that there is no advantage for this widget of
increasing the horizontal size past the minimum, allowing other
GUI elements to use the horizontal space if useful.
This change for caseCB is consistent with wordsCB and searchbackCB.
Now the minibuffer toolbar is "auto" by default. It is opened by
command-execute (M-x) and closed when the command is executed without error.
* make lyx::dispatch return a DispatchResult struct
* there is a new MINIBUFFER type of toolbar, that can be used for this use.
* remove special handling of M-x in minnibuffer; Escape can be used instead. Fix focus in this case.
* when minibuffer toolbar is "auto", make the toolbar close itself after
- a command has been executed without error
- an empty command has been executed
- the Escape key has been used
The horizontal size policy is now set to "MinimumExpanding", which
means that sizeHint() is enforced as a minimum, but that the widget
can make use of extra available space.
Before, the size policy was ignored, and often resulted in a
scrunched pane that had to have its size manually increased.
The symptom of the bug is that the preference could be incorrectly
displayed (based on the value of the statusbar preference).
This seems to have been a copy/paste mistake introduced in 214f7ed2.
Actually, the change is done only if the cursor language was the
document language already.
This fixes an trivial but annoying problem: create a new file (in
English), change language to your favourite language, then start to
write. Before this fix, the words come out in English, which does not
make sense.
Fixes bug #9586.
A new preference is introduced for allowing the record of the document
directory path in the saved file. Without explicit consent, it is not saved.
If the origin tag contains an invalid/wrong path or garbage, LyX behaves
exactly as before, i.e., included files are simply not found.
Create new helper class UndoGroupHelper, which simplifies a lot the
handling of undo groups in cases like this one. The class tracks open
undo buffers and allows to switch buffers transparently.
Using the class for advanced search and replace is trivial. THe class
may be useful in some other classes.
Fixes ticket #8658
Add a new tag HasGuiSupport to language file. Add it for all l10ns
that we currently ship. The po files that are unused are not currently
tagged as available, but this could be done, since the code later
checks that the translation is actually there.
This new information is used in GuiPrefs when populating the language
combox.
The new scheme implies that adding a new language is now a two-step
process:
* the language code has to be added to po/LINGUAS, as before;
* one of the entries of the lib/language file has to be selected as
reference and be given the "HasGuiSupport true" property.
LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the GUI part of bug 9416,
on top of part 1 [59e4d16ab/lyxgit].
There were now 2 entries named "none" in backgroundcolorCO
- delete the fixmes; the LateX name is used as parameter to save unnecessary conversions for the LateX output; please ask me before adding fixmes
stupid me, I used a translatable string as box parameter. Therefore the feature only worked correctly with English locale. Now it works for every locale.
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
The problem was due to the use of the wrong symbol for the slash.
The zero-width symbol for the \not operator was being used.
Using TeX fonts for all symbols gives now a better uniform look.
It is not possible using the alternative code even with Qt 5.4.1
because some glyphs are still missing.
Note that I move the definition of cur up because we need to check if
it changed before the return. I also removed the const because
notifyCursorLeavesOrEnters() requires that.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().
This fixes only part of #6173.
Normally the theBufferList().updatePreviews(); statement would go inside
of PrefDisplay::applyRC. However, that would not work well because
Buffer::updatePreviews() calls loader() which conditions on
(lyxrc.preview == LyXRC::PREVIEW_OFF) but the new RC has not been set at
this point.
Control + Shift + PgDn now moves a tab to the right.
Control + Shift + PgUp now moves a tab to the left.
These keybindings are consistent with Chromium, Firefox,
Nautilus, and gnome-terminal.
Note that I allow for wrapping. This is consistent with
allowing wrapping for buffer-{next,previous}, but there
might be reasons to disable it in the future.
buffer-next and buffer-previous are now only enabled
if there is more than one tab. Note that it does not
matter whether we are at the first or last tab because
we cycle.
Since the logout process still can be canceled here, we should only
check that all dirty buffers are saved and that the session state is
recorded.
Please test, particularly on Windows and OSX, that logging out with LyX
running (both with and without dirty buffers) proceeds sensibly and that
the LyX session is correctly restored when you re-login.
Building on cd8be655, we still allow viewing a produced PDF even if
there were compilation errors. However, now the user must click the
"Show Output Anyway" button in the LaTeX Errors dialog. The reason
is that before, there was a chance that the user would not realize
there was an error (because the PDF would be shown over the error
dialog). The approach in this commit makes it more clear that there
is an error.
A new LFUN is introduced, LFUN_BUFFER_VIEW_CACHE. It is useful not
just for the implementation of the "Show Output Anyway" button, but
also to show the last compiled version of a document, which can save
time if a document takes a long time to compile (e.g. heavy use of
knitr).
* Disable "New Inset" button
* Do not disable line edits, but use setReadOnly instead (this allows copying contents)
Fixes: #9408
Note that some dialogs still need some care.
The computation of length on screen depend in particular of the computation of the size of an em. Many places of the code used to rely on the width of the M character, which is not really correct:
http://en.wikipedia.org/wiki/Em_%28typography%29
In digital typography, the best value to use is the point size of the font.
* Implement FontMetrics::em(), which returns the value in pixels of the EM unit.
Convert code to use it.
* Introduce Length::inPixel(MetricsBase const &), which takes the textwidth and em information from the MetricsBase object. Convert code to use it.
* Fix several places where Length::inPixel is used without a proper em value.
* add mathed_font_em() helper function. It should eventually be removed like some other functions in MathSupport.
* Add dummy implementation of FontMetrics to tex2lyx for linking purposes.
The problem came from the fact that Qt associates Interlingua to locale C.
Now, we do not rely anymore on the Qt locale to set the language. I suspect that the problem will still exist if the system locale is ia_IA.
Fixes bug #9267.
If a compressed svg icon is present, load it instead of a png one.
Also introduce two more sizes (huge and giant icons) that should be
useful when using hires displays, as svg icons automatically scale
to the desired size without loss of quality.
The math icons for the symbol image in the math completer were hardcoded to the
command names. This is wrong for some icons for various reasons, e.g. the case
insensitivity of windows file systems. Therefore we have to use the replacement
list which is also used for the toolbar icons. Bug #3538 is not closed because
of this problem, but IMHO it has nothing to do with this bug, it is a more
general one.
After the str-metrics merge, the kludge for displaying symbols whose
code point corresponds to a soft-hyphen was not working anymore.
The solution is replicating the offending glyphs with index 0x00ad
at a different index. They were replicated at 0x00ac, whose glyph
was missing in all affected fonts.
However, this would not work by alone because, if a system font with
same family name exists, it would be picked up instead of the right one
(at least on non-Windows platforms). For this reason, the style of the
fonts has been changed from "Regular" to "Lyx", so that we can discriminate
the right font. However, this requires using at least Qt 4.8. If an
older Qt is used *and* a system font with same family name is already
available, the affected glyphs will all turn out on screen as the
"logical not" symbol.
I have also set the executable flag on the font files, because on Windows
they are loaded only in this case.
This solves #9229.
