The code was checking only for particular vertical alignment requests
in order to decide to nest a standard array into a 1x1 ams matrix.
However, also vertical lines are not possible in ams matrices.
Before, we would continually set the selection to the empty string,
to maintain ownership. This causes problems with clipboard managers
GPaste and CopyQ. Further, in theory this should have better
performance since checking ownership should be faster than setting.
A disadvantage of this change is that the timestamp of the selection
will be old at this point in the code. However, when the selection
is requested, we put the selection contents at that point so the
selection timestamp should be accurate then. Further, the selection
contents are not accurate at this point in the code (they are just
the empty string), so it is not clear whether having an accurate
timestamp is beneficial.
Fixes#11715.
Other than issuing a warning on the console, now the LyX window is
raised when in single-instance mode and no files to load are specified.
In this way, the user is aware that something happened after double
clicking the program icon. To support this functionality the new lfun
window-raise has been introduced.
Most of the RtL icons that we provide are simply mirrors of the LtR ones.
Therefore let the code do that by default if no +rtl icon is found.
The only RtL icon left for now is for "layout Enumerate" (notice the
numbers in it).
Also remove useless getPixmap wrapper and several old bidi_xxx icons
that were forgotten in previous patch.
When the cursor in RTL text, icons for "depth-increment" or
"layout-toggle Enumerate" look wrong.
Instead of relying on the clumsy "bidi" lfun of 2898c335, this new
version relies on a new Toobar tag BidiItem that inserts an action
which can have two icons, depending on the direction of the paragraph
containing the caret (or of the direction of the UI when no file is
open).
The alternative icon has the same name as the original one, with a
"+rtl" string appended to the lfun string. The alternative icon is
only active if the file is found. The icon themes `default', `oxygen'
and `classic' have been updated accordingly.
Fixes bug #4451.
There is a chance that this code is still useful for Qt 4. We keep
it around just in case.
For the case of Qt 4, this commit restores the code changed in
f8e40f8a, d255339a, and d4ff3a29.
Use QFontMetrics::boundingRect() instead. QFontMetrics::width() does
not actually calculate the width of the bounding box and is mostly
useful for knowing where to draw text after a string, taking into
account bearings. Indeed, it has been renamed to
QFontMetrics::horizontalAdvance().
For the code touched in this commit, we want to center a string.
Either method would likely be fine, but it is more easy to
understand exactly what QFontMetrics::boundingRect() does.
This commit does change functionality, although it should not be
noticeable.
Setting the family to "family" is already attempted above. A
different case was adapted to be this duplicate case at d4ff3a29,
but it should have just been removed.

This commit fixes the following warning from Qt 5.14:
error: ‘void QTreeWidgetItem::setTextColor(int, const QColor&)’ is deprecated: Use QTreeWidgetItem::setForeground() instead [-Werror=deprecated-declarations]
setForeground was introduced in Qt 4.2 [1].
We have a couple of commented out uses of a setTextColor() method in
GuiDocument.cpp, but the QTextEdit::setTextColor() is not deprecated so no
change is needed.

This commit fixes a few warnings from Qt 5.14 like the following
one:
error: ‘void QComboBox::setAutoCompletion(bool)’ is deprecated: Use setCompleter() instead. [-Werror=deprecated-declarations]
We only generated setAutoCompletion() from setting the property in
the .ui files. There does not seem to be a .ui file property that
generates setCompleter(). However, the default in both Qt5 [1] and
Qt4 [2] is to enable case-insensitive autocompletion, which seems to
be the same type of autocompletion as when we were relying on
setAutoCompletion(true). Thus, we can remove the properties that set
autocomplete to true. There is only one file, SearchUi.ui, where we
were turning off the autocompletion; we now do so using
setCompleter(0) in GuiSearch::GuiSearch().

Using a dialog may trigger a redraw at times where the metrics caches
have not been updated yet. To fix this, do as in paintEvent() and
abort caret blinking if there is an open undo group.
Move the decision to skip the caret painting to showCaret(), closer to
where real work happens. hideCaret () is now an alias for
showCaret(false), which allows some code refactoring.

Fixes bug #11763 (although it does not trigger on master).
This is a mode for includeonly handling that is effective and still outputs
at least mostly correct counters and references. This is intended for non-
final editing work.
File format change.
Fix warnings coming from deprecations of QTextEdit::tabStopWidth()
and QFontMetrics::width(). Regarding tabStopWidth(), the ChangeLog
states the following [1]:
Introduced tabStopDistance property in QTextOption, QTextEdit and
QPlainTextEdit as replacement for the inconsistently named tabStop and
tabStopWidth properties. QTextOption::tabStop, QTextEdit::tabStopWidth and
QPlainTextEdit::tabStopWidth are now deprecated.
Note that QFontMetrics::horizontalAdvance() is what we want here, as
opposed to QFontMetrics::boundingRect(), because we want to know
where to draw the next character after the tab.

Fix the following warning from Qt 5.14.1:
error: ‘static bool QPixmapCache::find(const QString&, QPixmap&)’ is deprecated: Use bool find(const QString &, QPixmap*) instead [-Werror=deprecated-declarations]
Fix the following warning from Qt 5.14.1:
error: ‘static QList<T> QList<T>::fromSet(const QSet<T>&) [with T = QString]’ is deprecated: Use QList<T>(set.begin(), set.end()) instead. [-Werror=deprecated-declarations]
Regarding QList::fromSet(), the documentation now states the
following [1]:
Since Qt 5.14, range constructors are available for Qt's generic
container classes and should be used in place of this method.

Fix the following warning:
error: ‘void QFileDialog::setConfirmOverwrite(bool)’ is deprecated: Use setOption(DontConfirmOverwrite, !enabled) instead [-Werror=deprecated-declarations]
Note in the change that "false" changes to "true" because the option
is *Dont*ConfirmOverwrite.
QFileDialog::setConfirmOverwrite() is obsolete at least since 4.8
and QFileDialog::setOption() is available since 4.5 [1].

Fixes the following warning:
error: ‘void QWidget::getContentsMargins(int*, int*, int*, int*) const’ is deprecated: use contentsMargins() [-Werror=deprecated-declarations]
The new code also has advantages in that 'l' can be set to const and
it is more readable because it is clear that only 'l' is used.
QWidget::getContentsMargins() was deprecated in 5.14.0 [1]. and
QWidget::contentsMargins() is available since 4.6 [2].
