Friedemann Kleint 1825426187 QtWidgets: Fix warnings about providing function for DESIGNABLE in property declaration

widgets/qgroupbox.h:60: Warning: Providing a function for DESIGNABLE in a property declaration is deprecated and will not be supported in Qt 6 anymore.

The toolbar properties were not caught by the warnings, but it appears
the checks do not work; the properties are designable when parented
on a non-QMainWindow parent.

Langonda Agag 0e0793ca59 Improve QTextDocumentPrivate cursor performance
The cursors in QTextDocumentPrivate are held in a QList.
This becomes a serious performance problem with lots of
extra selections due to a call to
QTextDocumentPrivate::removeCursor() from the QTextCursor
destructor.

Given the following test program:

    QPlainTextEdit *editor = ...
    std::list< QTextCursor> list;
    for(int i = 0; i < 100000; ++i) {
    QTextCursor c(editor->document());
    c.setPosition(std::rand()%100);
    list.push_front(c);
    }
    list.clear(); // <-- clear calls hangs for 3+ seconds
                  // due to time spent in
                  // QTextDocumentPrivate::removeCursor()
                  // due to QList::removeAll() call

Note the push_front because it exacerbates the issue because
the entire list will be traversed.

The change submitted changes the structure to a set,
removing the issue.
In theory, this limits that a cursors cannot be in the
structure twice, but this neither happens nor would it make sense.

Christian Ehrlicher 96c27eb710 QList/Table/TreeWidgetItem: Allow reseting values by passing the default value
The convenience functions setBackground(), setForeground() and
setSizeHint() a default constructed value as 'reset'. This means a

Therefore check if the passed value is a default constructed value and

Eskil Abrahamsen Blomfeldt e193459877 Fix kerning with fractional pixel size
Since most of our APIs for pixel size are integer-based, we
would assume it was when passing it to Harfbuzz. But QRawFont
(and the internal APIs in Qt and Harfbuzz) support floating
point pixel sizes. The result would be that setting e.g.
pixel size 20.25 would give the same glyph positions as 20.75,
but the glyphs would be some fraction of a pixel larger.

Using floats instead should have no impact on the common case
where the pixel size is an integer, but it should also enable
the other case, where QRawFont is used (or potentially future
APIs that do not have the integer limitation.)

[ChangeLog][QtGui][Text] Fixed a problem where pixel sizes
would be truncated before calculating glyph positions.

Thiago Macieira 8e8b50b061 RDRAND test: also disable if RDRAND produced only three samples
It's unlikely, since we do 64-bit RDRAND on 64-bit machines.

Thiago Macieira 737fd5550b Change the QtCore library output to show the plugin path
It's a lot more useful than the include dir. It actually helps debug
problems.

Florian Korsakissok 61def1f6cd HiDPI: Select most fitting pixel ratio when painting QIcon
There is a way to select a better pixel ratio when the QPainter has a
valid pointer to a QPaintDevice than simply getting the global app
pixel ratio.

Christian Ehrlicher 360df2cf74 QComboBox: add property placeholderText
QComboBox had no option to tell the user that he must select an item -
there was no placeholder text like e.g. in QLineEdit. This feature is
widely used in html forms so we should support it also.
Therefore add a new property 'placeholderText' to specify a text which
should be shown when the current selected index is invalid.

[ChangeLog][QtWidgets][QComboBox] QComboBox got a new property
'placeholderText'
