When entering an inset from the keyboard, setCurrentFont()
was not called and thus the cursor retained the font that was set
before. This could create strange behavior that could often go
unnoticed by the user.
It is easy to imagine many other situations similar to #9597 where
the user could trigger this bug.
Fixes bug #9597.
* 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.
Actually photos (i.e. .jpg files) where supported previously, but for pdflatex
output an unneeded conversion to png was done. The RasterImage templates
behaves now exactly as InsetGraphics for these files: If the input format is
jpg, use that for pdflatex, else convert to png.
This is another advantage of the new logo insets: We see in LyX where they are
inserted for the output. In these two cases, the text describes keywords of
the external template configuration file language, so these should not be
typeset as logos.
The difference to bitmap graphics is that these will be included as PDF for
pdflatex, so the vector properties are retained if a suitable conversion path
exists.
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.
In breakRow set left and right margin properly for RTL paragraphs.
Remove corresponding code from ComputeRowMetrics.
In row painter, check the use of left and right margin depending on
context. The problem in the original text is that the various
leftMargin() methods actually represent right margin for RTL
paragraphs. This should be fixed eventually.
This made text in smallcaps+emph display as upright instead of plain
emph. There is no latex font for smallcaps + emph, but it is not a
reason for displaying it wrong.
There are many things that are not necessary anymore:
* remove methods paintText2, paintFromPos, leftMargin, paintInlineCompletion
* Remove use of Bidi class.
* add a Font and a Change parameter to paintInset.
Also remove a comment that describes what we have just done.
The new version of paintText is quite short. Elements are treated one
by one. They are already in the right ordering.
The other changes are:
* a new paintChange method is added (using code lifted from old version)
* in paintLast, the support for end of paragraph markers is removed
(this is already part of the Row object.
This path configuration variable is used for user defined location.
There are other possible places for the thesauri like mythes installers or bundled with LyX.
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
The functions reverseDirectionNeeded() and reverseDirectionNeeded() do
not rely on the Bidi class. The first one is changed into a Cursor
method, and the second one is replaced with explicit code.
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.
The bug workaround added an extra repaint, which can be very bad when
editing large tables.
It turns out that the bug this is trying to fix is due to the handling
of LFUN_LINE_END in InsetMathGrid. Adding the same code as in
InsetMathNest fixes the problem.
The workaround can therefore be removed.
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 mismatch between the way text is tokenized in Row objects
and the way it is shown on screen. When metrics are computed,
continuous spell checking has not been done yet. Yet, the row painter
explicitly breaks words at spell status boundaries. This creates
problem with a text like "PMP," (see bug #9649), where there is a
negative kerning before the comma.
This is solved by not taking in account spell status when drawing
text, and drawing spell underlines separately.
* replace Paragraph::isSameSpellRange with new method getSpellRange.
* merge RowPainter::paintChars into RowPainter::paintFromPos
* move the actual text painting code into the new paintTextAndSel.
* merge some code from paintFromPos to paintMisspelledMark
* in paintMisspelledMark, scan the string which needs to be annotated
and add dashed line below text marked as misspelled.
Fixes bug #9649.
This avoids warnings with windows compiler. It is a pity that even
clang does not give those. Maybe I missed them with the large amount
of boost warnings that it spits.
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.
