1869615fc9 QChar: make construction from integral explicit
QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).

David provided the perfect example:

  if (str == 123) { ~~~ }

compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.

Add a macro to revert to the implicit constructors, for backwards
compatibility.

The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

18e8519dcd Win: Choose a suitable font in tst_QTextLayout::textWidthVsWIdth
The default font on Windows 10 (Segoe UI) will return the
wrong minimum right bearing at some sizes, which will cause
us to skip the textWidthVsWIdth() test at some scale factors,
since we cannot trust the layout to be perfect in this case.

Based on experiment, Arial is more accurate, so in order to
avoid skipping the test, we default to this on Windows instead.
(Note: The problem has not been observed with the default fonts
on Linux or macOS, so we only do this for Windows specifically.)

8d6d1d6fea Fix bug in QTextLayout::min/maxWidth for WrapAtWordBoundaryOrAnywhere
In that specific wrapping mode, it will first try a normal word wrap. If
it doesn't fit within the specified line width it will discard the
result of that and try WrapAnywhere by calling layout_helper()
recursively. The problem was that at the point it called itself again it
had already adjusted eng->maxWidth:

        eng->maxWidth += line.textWidth;

This was not restored, but carried on to the recursive call to
layout_helper(), so the end result was that the maximumWidth would
accumulate text widths from parts of the same line twice.

Due to the same recursive behavior the minimumWidth also had a problem:
It always returned the width of the widest word because it took the
qMax() of the minimum widths of the two passes, (WordWrap and then
WrapAnywhere) effectively making the minimum width always be the width
of the widest word (even though it could wrap at finer granularity).

a ligature for "fi", so the test would not actually be testing
what it was supposed to on this platform, and would pass even

To enable the test on Windows, we select a standard font which
has the ligature (Calibri).

af6ac444c9 Fix crash when text contains too many directional chars

The function initScriptAnalysisAndIsolatePairs() collects information of
RTL/LTR chaaracters into vector "isolatePairs". The size of the vector is
capped to 128. Later the function generateDirectionalRuns() iterates
the text again and tries to access items from the previously capped vector
above the upper bound.

65a1d41a09 Fix potential crash when showing line/paragraph separators
When showing line and paragraph separators at an offset from the start
of the string, the end of string pointer would be incorrectly set, and
we would read past the end of the string. If any part of this memory
happened to match the line or paragraph separator, then we would
overwrite it and have a crash.

I couldn't find any reliable way to test this, since the crash depends on
the contents of the memory after the string allocated by the algorithm.
But with an overflow of 100 000 characters, I found that it crashed every
time I ran the test.

It is worth noting that many or most of the usages of

but since it currently works, I have not looked into that, just
replaced the function name mechanically.

d1bab5b1e3 Allow word break wrapping in Korean text
In Korean text, they typically can use both the "Western" style of
word wrapping, i.e. breaking on spaces, as well as the East-Asian
style of potentially breaking between all syllables. However,
the Unicode Line Breaking Algorithm, TR14 defaults to breaks on
syllables and specifies a possible tailoring where Hangul is
mapped to the AL class instead:

"When Korean uses SPACE for line breaking, the classes in rule
LB26, as well as characters of class ID, are often tailored to AL"

When using Qt, the user would expect the WordWrap wrap mode to
break between words in Korean. If you want the syllable-based
text layout, you would use WrapAnywhere, probably accompanied
by line justification.

To avoid breaking QTextBoundaryFinder and other potential clients
of QUnicodeTools which depend on getting the precise Unicode
data from the algorithm, we do this by passing a flag from
QTextEngine when initializing the attributes. This way, it
can also be made optional later on, if we decide there is
a reason to add an additional wrap mode specifically to
handle cases like this.

[ChangeLog][Important Behavioral Change] WrapWord now
correctly prefers line breaks between words in Korean text.
WrapAnywhere can still be used to get breaks between syllables
instead.

9342a8b843 Add QTextOption/QTextEdit/QPlainTextEdit::tabStopDistance property
In Qt, we have QTextOption::tabStop, QTextEdit::tabStopWidth and
QPlainTextEdit::tabStopWidth.

Neither are very good names, since the tab stop is neither a
numerical value as in the former, nor does it have any dimensions
that can be measured, as in the latter. Vertical text advances
may also be supported by Qt at some point in the future, at
which point the name would make even less sense.

At the same time, we expose the actual type of the tab stop
distance as floating point in the QTextEdit and QPlainTextEdit
API instead of always rounding it to an int.

To avoid duplicating either of these APIs in Qt Quick, we
introduce tabStopDistance as the common term instead and deprecate
the old names.

[ChangeLog][Text] Introduced tabStopDistance property in
QTextOption, QTextEdit and QPlainTextEdit as replacement for
the inconsistently named tabStop and tabStopWidth properties.

15414257b3 Don't count no-break spaces as trailing spaces
No-break-spaces should not be counted in the space data, but rather
be treated as any other non-breakable character. We were already
taking care of this in the loop we reach if the item starts with
a character which isn't whitespace, but there is a second loop for
items that begin with whitespace characters.

The result of this was that in certain circumstances where you gave
the nbsp its own format and made the line wrap, the previous line
would count an extra trailing space and it would swallow the first
character in its following line.

sometimes cause the first character of the containing line to not be

After e109b8a0f3, it is possible
that the cache will be flushed as a result of inserting a new
font rather than just when the timer event triggers. When doing
superscript and subscript text layouts, we would first get
a regular font engine, then a scaled one, and then reference
the regular font engine *after* getting the scaled one. If the
regular font engine was deleted as a result of inserting the scaled
one, we would get a dangling pointer and crash.

The situation was improved by 49926bb9ef.
You would now to switch between 256 different fonts in the layout

54dbdc26ba Move min left/right bearing calculations to QFontEngine baseclass
The logic used in the FreeType font engine can be generalized
and move to the QFontEngine baseclass. This allows the CoreText
font engine to correctly report the minimum left/right bearings,
which decreases the chance that an optimization in QTextLayout's
line breaking algorithm will produce wrong results.

The calculation of left and right bearing has been moved to the
glyph_metrics_t type to reduce code duplication. This allows us
to use the with and height of the bounding box to determine if
the glyph has any contours.

ccf50893e8 Skip incompatible QTextLayout tests when dpi-scaling is used
On e.g. Android, the tabs will be scaled by DPI. This breaks the
logic in the QTextLayout tests for tabs. It's not possible to
just scale the expected sizes either, since the whole text layout
will be affected by font sizes and scaling, and it's difficult to
predict where characters will land on different platforms and
resolutions.

To avoid breaking this test on other platforms, we just skip them
when we know they will break. Since the code tested is
cross-platform, this will hopefully not have any significant
impact on our coverage.

b56a42be14 REG: Fix nbsp in QTextLayout
At some point since Qt 4.8, the nbsp character has acquired
the whitespace attribute, causing it to be treated exactly
like an ordinary space. To account for this, we add an extra
check in the layout code to avoid breaking on non-breaking
spaces even if they have the whiteSpace flag set.

This is a temporary fix for the regression. The line breaking
algorithm needs to be refactored and support Unicode tr14
properly, which it currently doesn't.

[ChangeLog][Text] Fixed lines breaking on non-breaking spaces.

7eae50a52d Fix assert on justification of QTextLine with only spaces
In the justification code, we unconditionally subtracted one
from the line_length, but then compared the result to 0 afterwards,
so we did not support when the line_length is 0 initially, which
can happen if it only consists of spaces (in which case
trailingSpaces will be non-zero and line_length will be zero.)
The fix is to bail out for both strings of length 1 and length 0.
