The crash #9788 would not have happened if this had been done earlier.
Use the function support:truncateWithEllipsis() to shorten a docstring with
... at the end. Actually we use U+2026 HORIZONTAL ELLIPSIS instead of "..." when
automatically shortening strings. This is to be consistent with Qt's own
truncation and is much nicer on the screen.
This includes the bugs #9575 and #9572 regarding broken text elision in the
outliner.
Known issues (non-regressions):
* TocBackend::updateItem() should be rewritten to update all TOCs. (#8386)
* "..." should be replaced with … everywhere else on the interface (including
translation strings).
* We should prefer to rely on QFontMetrics::elidedText() to truncate strings
with an ellipsis whenever possible, or an equivalent for the buffer view
dependent on the font metrics. See the warning in src/support/lstrings.h.
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.
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.
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 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.
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.
FileName::tempName() created a new temp file name by using qt to create a
temporary file with a unique name, and then deleting that file and returning
the name. This was unsafe, since other processes or even other threads of the
running LyX could create files with the same name between deletion and then
using the temp name.
This is fixed by using the TempFile class instead. As a side effect, a few
cases where the temp files were not deleted after usage were fixed as well.
The only place that is still unsafe is createTmpDir().
for possible thread conflicts, of the sort Georg resolved at

and marked cases that looked potentially problematic with the
comment:
// FIXME THREAD
Many of these definitely are vulnerable to concurrent access, such
as the static variables declared at the start of output_latex.cpp.
Suppose, e.g., we were outputting latex and also displaying the
source of a different document.
I'd appreciate it if others could grep for "FIXME THREAD" and see
if some of these are harmless, or what.

When there is a single document open, the tabbar gets hidden. The only and selected tab is still visible though as a break in the line delining the tabwidget. To fix this we paint the tabwidget ourselves and remove the presence of the hidden tab.
If no mask is supplied or the mask is attached to the end of the filename, we end up with unexpected names like
<system-temp-dir>\lyx_tmpdir.qHp780.vcr780_<mask>
instead of a temporary file in the lyx temporary directory like
<system-temp-dir>\lyx_tmpdir.qHp780\<mask>.vcr780.
This option is set to true by default as this is the most widespread use case.

Two things have been fixed here:
1) the selection should not be cleared when the user right clicks a math inset that is part of the selection,
2) the type of context menu should be determined at mouse-press, because that is the moment when the cursor is set. However, we should do it after setting the cursor, because setting the cursor might change the selection status and this influences the choice for the type of context menu.
