638ac41293 CMake: Fix painting examples to build as standalone projects
The examples use an intermediate object library to avoid duplicate
file compilation. The examples worked when built as part of Qt
because the shared directory was always added, and Qt::OpenGL is
available implicitly.

Change each project to add_subdirectory(../shared) if the object
library is not available, thus making the examples build as standalone
projects.

Call find_package inside the shared project, to ensure the Qt packages
are found.

Create an alias called 'painting_shared::painting_shared' and link
against that to ensure that any failure is caught at configure time
rather than build time.

Adapt the pathstroke example to use the object library.

Comment out the code for the OpenGL scopes, because it's handled
by the object library.

Make sure the OpenGL dependency is public.
Make sure to run moc and compile the OpenGL specific files as well.

89f7a2759c Deliver Quit event when calling QCoreApplication::quit()
Instead of QCoreApplication::quit() directly calling exit(0), which would
leave QGuiApplication and client code out of the loop, we now send the
Quit event, and let it pass through event delivery, before finally ending
up in QCoreApplication::event(), where we call exit(0).

This has the advantage that QGuiApplication can ensure all windows are
closed before quitting, and if any of those windows ignore the close
event the quit will be aborted. This aligns the behavior of synthetic
quits via QCoreApplication::quit() with spontaneous quits from the
platform via QGuiApplicationPrivate::processApplicationTermination.

Clients who wish to exit the application without any event delivery or
potential user interaction can call the lower level exit() function
directly.

[ChangeLog][QtGui] Application termination via qApp->quit() will now
deliver Quit events to the application, which in turn will result in
application windows being closed as part of the application quit,
with an option to cancel the application quit by ignoring the close
event. Clients who explicitly want to exit the application without
any user interaction should call QCoreApplication::exit() explicitly.

25351dcc54 Long live QKeyCombination!
C++20 via P1120 is deprecating arithmetic operations between
unrelated enumeration types, and GCC 10 is already complaining.
Hence, these operations might become illegal in C++23 or C++26 at
the latest.

A case of this that affects Qt is in key combinations: a
QKeySequence can be constructed by summing / ORing modifiers and a
key, for instance:

  Qt::CTRL + Qt::Key_A
  Qt::SHIFT | Qt::CTRL | Qt::Key_G (recommended, see below)

The problem is that the modifiers and the key belong to different
enumerations (and there's 2 enumerations for the modifier, and one
for the key).

To solve this: add a dedicated class to represent a combination of
keys, and operators between those enumerations to build instances
of this class.

I would've simply defined operator|, but again docs and pre-existing
code use operator+ as well, so added both to at least tackle simple
cases (modifier + key).

Multiple modifiers create a problem: operator+ between them yields
int, not the corresponding flags type (because operator+ is not
overloaded for this use case):

  Qt::CTRL + Qt::SHIFT + Qt::Key_A
  \__________________/      /
          int              /
           \______________/
                  int

Not only this loses track of the datatypes involved, but it would
also then "add" the key (with NO warnings, now its int + enum, so
it's not mixing enums!) and yielding int again.

I don't want to special-case this; the point of the class is
that int is the wrong datatype. Everything works just fine when
using operator| instead:

  Qt::CTRL | Qt::SHIFT | Qt::Key_A
  \__________________/      /
      Qt::Modifiers        /
           \______________/
            QKeyCombination

So I'm defining operator+ so that the simple cases still work,
but also deprecating it.

Port some code around Qt to the new class. In certain cases,
it's a huge win for clarity. In some others, I've just added
the necessary casts to make it still compile without warnings,
without attempting refactorings.

[ChangeLog][QtCore][QKeyCombination] New class to represent
a combination of a key and zero or more modifiers, to be used
when defining shortcuts or similar.

[ChangeLog][Potentially Source-Incompatible Changes] A keyboard
modifier (such as Qt::CTRL, Qt::AltModifier, etc.) should be
combined with a key (such as Qt::Key_A, Qt::Key_F1, etc.) by using
operator|, not operator+.  The result is now an object of type
QKeyCombination, that stores the key and the modifiers.

c501e09efa Replace QAbstractItemView::viewOptions with initViewItemOption
viewOptions returned a QStyleOptionViewItem object. Such a method
can never support newer versions of the option structure.

Most styleable QWidget classes provide a virtual method
initStyleOption that initializes the option object passed in as a
pointer, e.g QFrame, QAbstractSpinBox, or QComboBox.

Follow that API convention, but name it initViewItemOption, as the
QStyleOptionViewItem struct contains information about the item as
well as the widget itelf.

This is a source incompatible change that will go unnoticed unless
existing subclasses mark their overrides as 'override', or call
the removed QAbstractItemView::viewOption virtual function.

[ChangeLog][QtWidgets][QAbstractItemView] The virtual viewOptions
method that previously returned a QStyleOptionViewItem object has
been renamed to initViewItemOption, and initializes a
QStyleOptionViewItem object that's passed in through a pointer.

1697fbdf05 Deprecate the static int based API in QMetaType
And remove one of the type id to name mapping that still
existed in QMetaType. QMetaTypeInterface can provide that,
so there's no need to have a second copy of the data.

qMetaTypeTypeInternal() can still map all the names of all
builtin types to ids. That functionality is for now still
required by moc and can't be removed yet.

a8028a02df Port the QXmlStream API from QStringRef to QStringView
This gives some source incompatibilities, most of them can be
handled by using auto instead of QStringRef explicitly.

[ChangeLog][Important API changes] QXmlStream now uses QStringView
insteead of QStringRef in it's API. Using auto forvariables returning
a QStringRef in Qt 5 should lead to code that can be used against both
Qt versions.

Fixes: QTBUG-84317

f741a12de1 Disentangle QIODevice dependencies
Move the QIODevice::OpenMode enum into a base class, so that
we can remove the full QIODevice (and thus QObject) dependency
from qdatastream.h and qtextstream.h.

This is required so that we can include QDataStream in qmetatype.h
without getting circular dependencies.

As a nice side effect, QDataStream and QTextStream can now inherit
QIODeviceBase and provide the OpenMode enum directly in their
class scope.

14090760a8 Long Live QMap as a refcounted std::map!
... and QMultiMap as std::multimap.

Just use the implementation from the STL; we can't really claim that
our code is much better than STL's, or does things any differently
(de facto they're both red-black trees).

Decouple QMultiMap from QMap, by making it NOT inherit from
QMap any longer. This completes the deprecation started in 5.15:
QMap now does not store duplicated keys any more.

Something to establish is where to put the
QExplictlySharedDataPointer replcement that is in there as an
ad-hoc solution. There's a number of patches in-flight by Marc
that try to introduce the same (or very similar) functionality.

Miscellanea changes to the Q(Multi)Map code itself:

* consistently use size_type instead of int;
* pass iterators by value;
* drop QT_STRICT_ITERATORS;
* iterators implictly convert to const_iterators, and APIs
  take const_iterators;
* iterators are just bidirectional and not random access;
* added noexcept where it makes sense;
* "inline" dropped (churn);
* qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE);
* operator== on Q(Multi)Map requires operator== on the key type
  (we're checking for equality, not equivalence!).

Very few breakages occur in qtbase.

[ChangeLog][Potentially Source-Incompatible Changes] QMap does not
support multiple equivalent keys any more. Any related functionality
has been removed from QMap, following the deprecation that happened
in Qt 5.15. Use QMultiMap for this use case.

[ChangeLog][Potentially Source-Incompatible Changes] QMap and
QMultiMap iterators random-access API have been removed. Note that
the iterators have always been just bidirectional; moving
an iterator by N positions can still be achieved using std::next
or std::advance, at the same cost as before (O(N)).

[ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does
not inherit from QMap any more. Amongst other things, this means
that iterators on a QMultiMap now belong to the QMultiMap class
(and not to the QMap class); new Java iterators have been added.

a83b2c64a9 Polish the settingseditor example
The example is meant to show an item delegate with a line edit with
QRegularExpression-based validation depending on type.
Unfortunately, this does not work since QSettings mostly
return QString types.

Fix it to a partially working state by
- Making the expressions match from beginning to end which
  was overlooked in the QRegExp->QRegularExpression change.
- Use QCheckBox, QSpinBox for bool/int since it is silly
  to have a user edit a bool value by typing 'true'/'false'.
- Move the expressions out to a separate struct to be
  able to do some guessing of the type when reading
  the QSettings, implement for bool and int.
- Use a fancy Unicode checkmark for displaying bools.
- Fix the garbled display of QByteArray with binary data
  by displaying them with hex characters and setting them
  read-only.

df853fed66 Use qsizetype in QList
The change creates a slight source incompatibility. The main
things to take care of are

* code using printf statements on list.size(). Using qsizetype in
printf statements will always require a cast to work on both 32
and 64 bit.
* A few places where overloads now get ambiguous. One example is
QRandomGenerator::bounded() that has overloads for int, uint and
double, but not int64.
* Streaming list.size() to a QDataStream will change the format
depending on the architecture.

[ChangeLog][QtCore][QList] QList now uses qsizetype to index into
elements.
