fa93f1aeb0 Fix compile time type normalization code
Use a simpler constexpr to generate type name on gcc This
works around an ICE on gcc in release mode when compiling
with PCH enabled. As the type we're getting from Q_FUNC_INFO is
already in a somewhat normalized form, this requires significanlty
less processing and esp. not a recursive constexpr method which
I suspect triggers the ICE.

Fix integer type conversions to also properly normalize long long
values (to q(u)longlong. Make sure the mapping also works on
MSVC, where long long types get mapped to __int64. Also, normalize
unsigned short and unsigned char to ushort and uchar, respectively, to
follow the convention set by uint and ulong.

Add some test cases to verify the mappings.

ba511b2fa4 Reject overwrites by the same index in QPromise::addResult()
One can call addResult(value, index) twice and consequently set the
value twice by the same index. This seems rather strange and probably
should not be allowed. This commit rejects setting results when there's
already a valid result by that index. Consequently, this fixes memory
leaks caused by N-times-called addResult(..., index)

044231c4d2 Remove timeStep parameter from QAnimationDrive::advanceAnimation
This reverts commit 7544c242cb, which
reverted the first removal of the parameter under the assumption
that it caused flakiness in tests.

The flakiness was instead caused by changes to the wait functions
in QTest, so remove the parameter again.

b83225fcc3 qDebug: Avoid implicit QVariant conversion
This commit restricts operator<<(QDebug lhs, QVariant rhs) to only work
if rhs is actually of type QVariant (instead of any type convertible to
QVariant). This is especially important as
a) we check in QMetaType whether (slightly simplified) QDebug{} <<
   std::declval<T>() is valid, and if so, register a function which
   simply uses the operator.
b) In QVariant, we ask the metatype system for the contained types
   registered debug function and then use it.
If a type now does not have its own operator<< for QDebug, but is
implicitly convertible to QVariant containing itself, this would lead to
an infinite recursion, when trying to use qDebug with that type. The
registered function in a) would just convert the type to QVariant, and
then ask the QVariant to print itself.
Disallowing implicit conversions in qDebug in general was considered
(i.e. adding template<typename T> operator<<(T) = delete in QDebug ),
but discarded as it breaks too much code relying on conversions.

cb0ecd6b6d Check value is in range when setting a QDateTime
Previously, a QDate representing more than about 0.3 gigayears before
or after the epoch would overflow the millisecond count and produce a
"valid" date-time that didn't represent the date and time passed to
its constructor.  Changed to detect such overflow and produce an
invalid date-time instead, if it happens.

Corrected some tests that wrongly expected to be able to represent
extreme date-time values with every time-spec.  The (milli)seconds
since epoch are from UTC's epoch, so converting to another offset,
zone or local time may give a value outside the actual range.  Added
some tests for the actual exact bounds.

e5dc46d966 Allow millisecond-overflow when the result remains valid
Even before adding support for fractional hours, a fraction of a
minute might potentially have represented a whole number of seconds by
a fractional part that, due to rounding, was less than the whole
number of seconds by less than half a millisecond. Previously, the
parsing would have clipped the fractional part at 999 milliseconds, in
the preceding second, instead of correctly rounding it up to the whole
second.

For QTime::fromString(), which can't represent 24:00, and for
TextDate, which doesn't allow 24:00 as a synomym for the next day's
0:0, applying such rounding to 23:59:59.999999 would produce an
invalid result from a string that does represent a valid time, so use
the nearest representable time, as previously.

Added some tests and amended others.

[ChangeLog][QtCore][QDateTime] QDateTime and QTime, in fromString()
with format ISODate or TextDate, now allow a fractional part of the
hour, minute or seconds to round up to the next second (hence
potentially into the next minute, etc.) when this is the closest
representable value to the exact fractional part given. When rounding
up would turn a valid result into an invalid one, however, the old
behavior of clipping to 999 milliseconds is retained.

97de53ee8c QUrl::fromLocalFile: accept invalid hostnames
QUrl hostnames must be compliant with STD3, but we must somehow accept
file paths that begin with double slash but aren't valid hostnames.
Because the file URI spec requires us to start with "file://" anyway, we
can represent those with four slashes. Note that on Unix "//X/y" is a
valid but local file path. If given to QUrl::fromLocalFile(), if the
path at the root does parse as a hostname, we will still try to
normalize (the above becomes "file://x/y").

[ChangeLog][QtCore][QUrl] Changed QUrl::fromLocalFile() to accept
Windows UNC paths whose hostname component is not a valid Internet
hostname. This makes QUrl able to accept extended-length paths (\\?\),
device namespace (\\.\),  WSL (\\wsl$), etc.

4e675cb85e Handle trailing cruft consistently in Qt::DateFormat parsing
Previously the ISO time format would tolerate trailing cruft at the
end in various cases even though there might be an offset specifier
after the time, which should *not* be separated from it by anything
(not even the spaces we originally planned to still tolerate).

The RFC date format is forgiving about space, as is suitable for
parsing of RFC-822 headers, but the other formats should match the
handling in QDateTimeParser, which rejects any dangling cruft.

At the same time, since this required a re-write of
fromIsoTimeString() in any case, add support for the ISO format that
gives the hour a fractional part and skips minutes and
seconds. Previously we only had support for fractional minutes (with
no seconds). The hour without even a fractional part is also valid.

Reworked the documentation of Qt::DateFormat as it was wrong in
places, inconsistent in its formatting and incomplete. Adjusted some
tests to match the new behavior. A fraction separator with no
following digits should have been recognized as an error previously
and now is.

[ChangeLog][QtCore][QDateTime] The ISODate and ISODateWithMs formats
now reject trailing cruft (including spaces) at the end of a time
string. They also gain support for parsing hour-only formats,
including the hour-with-fractional-part format.

1c591fd924 Deal with {und,ov}erflow issues in QLine's length handling
Use std::hypot() instead of sqrt() of a sum of squares.
This ensures length() can't be zero when isNull() is false.
Use length() in QLine::setLength() rather than duplicating that.

Clarify and expand some documentation; isNull() never said what
constituted validity, nor did unitVector() mention that is should not
be used on a line for which isNull() is true. Make clear that lines of
denormal length cannot be rescaled accurately.

Given that we use fuzzy comparison to determine equality of
end-points, isNull() can be false for a line with displacements less
than sqrt(numeric_limits<qreal>::denorm_min()) between the coordinates
of its end-points (as long as these are not much bigger); squaring
these would give zero, hence a zero length, where using hypot() avoids
the underflow and gives a non-zero length. Having a zero length for a
line with isNull() false would lead to problems in setLength(), which
uses an isNull() pre-test, protecting a call to unitVector().

(It was already possible for a null line to have non-zero length; this
now arises in more cases.)

Restored QLine::setLength() to the form it had before a recent change
to avoid division by zero (which resulted from underflow in computing
the length of a non-null line) but allow for the possibility that the
unit vector it computes as transient may not have length exactly one.

Add tests against {ov,und}erflow problems in QLine. Reworked the test
added during the divide-by-zero fix to make it part of the existing
test.

We were missing 64-bit signed mul_overflow on 32-bit platforms and in
those where we did have it, the detection was awful (both for signed and
for unsigned). So if one of the parameters is a constant, we can
simplify the code generated.

1e883cf9b5 Prevent endless markDirtyAndNotifyObservers <-> notify loop
Before we had the option of eager evaluation, we were able to use the

in turn will clear the dirty flag.
Introduce a new member to detect that situation, and set the bindings
error state to BindingLoop if we detect that kind of loop.

QVariant similar to the convert family. The new methods are non-const
and expect the original value to stay available during the life time of
the view.

ac7e518a64 [QtCore] Fix QDateTime unit test: time zone of system was used
Test data for QDateTime unit tests was constructed in system's local
time, which made unit test outcome dependent on the time zone of the
system running the tests.
This led to failing unit tests on systems with libc6 version
2.31 or newer. A QDateTime in a timezone, which has daylight saving
time, was created and then used in Hawaii's time zone,which has no
daylight saving time. Newer glibc checks this and returns errors.
This patch changes the behavior to create the test data in a
specified time zone setting.

db3d5a3097 Fix flaky QTimer::remainingTime() test
Before, we used not so accurate QTest::qWait(50)
to measure the accuracy of more precise timer's interval.
In addition, the checked range for remainingTime (50, 200)
was probably wrong, since by definition it couldn't be more than 150,
as we started the timer with interval of 200 and waited at least 50.

In this fix we have additional "tester" timer to measure remainingTime
of "tested" timer. The "tester" is a singleShot timer with interval of
50, and is started together with "tested" timer. Whenever the "tested"
timer timeouts, it restarts the "tester" timer - this is done desired
number of times (2 by default, like in the original test).

The test itself lies now inside tester's lambda. We fix the tested
range (at least 1, no more than 150). The minimum value could in
theory be greater, but it's enough to test that it's not overdue.

Finally, we wait for expected number of test runs. We give it twice
as much time as is in theory needed.

7e93870401 QProcess/Unix: introduce setChildProcessModifier()
[ChangeLog][Source-Incompatible Changes] QProcess::setupChildProcess()
was removed. To execute code in a child process, use
QProcess::setChildProcessModifier()

[ChangeLog][QtCore][QProcess] Added setChildProcessModifier() function
with which one can provide code to be run in the Unix child process
between fork() and execve(). With this function, it is no longer
necessary to derive from QProcess in order to execute actions in the
child process.

Another reason is that we can tell whether the std::function carries a
valid target much more easily than we can tell whether QProcess was
overridden.

The setupChildProcess() virtual function does not need to be marked
final, since no overrider could ever return an inaccessible private
class. This also makes sure the error presented to the user is about the
return type, not about attempting to override a final.

Clang:
 error: virtual function 'f' has a different return type ('void') than the function it overrides (which has return type 'QProcess::Use_setChildProcessModifier_Instead')

GCC:
 error: conflicting return type specified for 'virtual void MyProcess::setupChildProcess()'
 note: overridden function is 'virtual QProcess::Use_setChildProcessModifier_Instead QProcess::setupChildProcess()'

ICC:
 error: return type is neither identical to nor covariant with return type "QProcess::Use_setChildProcessModifier_Instead" of overridden virtual function "QProcess::setupChildProcess"

MSVC is not relevant since it doesn't compile to Unix.

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.

39e07ebf64 Long live QAIM::multiData!
Views / delegates absolutely *adore* hammering data(). A simple
QListView showing a couple of dozens entries can call data()
a hundred of times on the first show.

Back of the hand calculation,

* 2 times per visible item (sizeHint() + paint()),
* times 9 roles used by the default delegate,
* times 20 visible items

= 360 as a bare minimum, assuming the view doesn't redraw twice
accidentally. Move the mouse over the view, and that'll cause
a full update with certain styles: 360 calls to data() per update.

This has an overhead visible in profilers. The model's data()
has to re-fetch the index from its data structure and extract
the requested field every time.

Also, QVariant is used for the data interexchange,
meaning anything that won't fit in one is also a memory allocation.
This problem will likely be gone in Qt6Variant as that
will store sizeof(void*) * 3, meaning QImage/QPixmap and similar
polymorphic classes will fit in a QVariant now...

So I'm trying to to remove part of that overhead by allowing
views to request all the data they need in one go. For now,
one index a a time.

A view might also store the data returned. The idea is that
the same role on different indexes will _very likely_
return variants of the same type. So a model could move-assign
the data into the variant, avoiding the memory allocation
/deallocation for the variant's private.

This patch:

1) Introduces QModelRoleData as a holder for role+data.

2) Introduces QModelRoleDataSpan as a span over QModelRoleData.
The idea of a span type is twofold. First and foremost, we are
in no position to choose which kind of container a view should
use to store the QModelRoleData objects for a multiData() call;
a span abstracts any contiguous sequence, leaving the view free
to do whatever it wants (statically allocate, use a vector, etc.).
It also solves the problem of efficient passing the roles and
gathering the returned variants from multiData().

3) Add multiData(), which populates a span of roles for a given
model index. The main advantage here is that a model can fetch
all the needed information for a given index just once, then
iterate on the span and provide data for each requested role.
Cf. this with data(), where every call has to re-fetch
the information for the index.

A couple of models have been ported to multiData(), as well as
QStyledItemDelegate.

[ChangeLog][QtCore][QModelRoleData] New class.

[ChangeLog][QtCore][QModelRoleDataSpan] New class.

[ChangeLog][QtCore][QAbstractItemModel] Added the multiData()
function.

ad32ac5b4f Make bindings introspectable through moc

where to find the QBindable for the property.

Add a QUntypedBindable base class to QBindable<T> that gives access to

QBindable<T> will still do static checking at compile time.

Add QMetaProperty::isBindable() and QMetaProperty::bindable()

that is bindable inside a QObject or QObjectPrivate. The property
only uses as much space as the data contained, ie. it has no

11b8c46d2a QObject: add a single shot connection flag
If one needed to listen to a signal just once, one had to
store the QMetaObject::Connection object returned by connect()
and use it to disconnect the slot after the first signal
activation.

This has led to a proliferation of using wrappers (and enough
TMP); they usually look like this:

1) create a shared_ptr<QMO::Connection>, allocating its payload;
2) create a lambda, capturing the shared_ptr by value;
3) in the lambda, disconnect the connection (through the shared_ptr),
   and call the actual slot;
4) connect the signal to the lambda, storing the returned
   QMO::Connection into the shared_ptr.

This is expensive, error prone for newcomers, and tricky to
support as a general facility inside one's projects.
We can do better, just support single shot connections right
in QObject.

[ChangeLog][QtCore][QObject] Added the Qt::SingleShotConnection
flag. When a connection is established with this flag set,
the slot is going to be activated at most once; when the signal
is emitted, the connection gets automatically broken by Qt.

2c9529e158 Long live Q{Any,Utf8}StringView!
We need to add these two classes at the same time, because
QAnyStringView makes all QUtf8StringView relational operators moot. We
might want to add some later, esp. for UTF-8/UTf-8 comparisons, to
avoid the pessimization that we can't early-out on size() mismatch in
QAnyStringView equality operators, but that's an optimization, not a
correctness issue, and can be fixed in a source-compatible way even
after Qt 6 is released.

To deal with the char8_t problem in C++20, make QUtf8StringView a
class template out of which two UTF-8 views can be instantiated: the
Qt 7 version, which depends on C++20 char8_t as value_type, and the Qt
6 version where value_type is a char. Use inline namespaces to map the
QUtf8StringView identifier to one or the other, depending on the C++
version used to compile the user code. The inline namespace names must
needs be a bit ugly, as their inline'ness depends on __cpp_char8_t. If
we simply used q_v1/q_v2 we'd be blocking these names for Qt inline
namespaces forever, because it's likely that inline'ness of other
users of inline namespaces in Qt depends on things other than
__cpp_char8_t. While inline'ness of namespaces is, theoretically
speaking, a compile-time-only property, at least Clang warns about
mixed use of inline on a given namespace, so we need to bite the
bullet here. This is also the reason for the QT_BEGIN_..._NAMESPACE
macros: GCC is ok with the first declaration making a namespace
inline, while Clang warns upon re-opening an inline namespace as a
non-inline one.

[ChangeLog][QtCore][QUtf8StringView] New class.

[ChangeLog][QtCore][QAnyStringView] New class.

78cf89c07d Use checked string iteration in case conversions
The Unicode table code can only be safely called on valid code-points.
So code that calls it must only pass it valid Unicode data. The string
iterator's Unchecked Unchecked methods only provide this guarantee
when the string being iterated is guaranteed to be valid UTF-16; while
client code should only use QString, QStringView and friends on valid
UTF-16 data, we have no way to be sure they have respected that.

So take the few extra cycles to actually check validity in the course
of iterating strings, when the resulting code-points are to be passed
to the Unicode table look-ups. Add tests that case mapping doesn't
access Unicode tables out of range (it'll trigger the new assertion).
Added some comments to qchar.h that helped me understand surrogates.

growing (e.g. reserve/squeeze)

when reallocation is preferable over just using the insert-like
operation. This comes up later on when GrowsBackwards policy is
properly supported in operations

are introduced here. The last one being a generalized data move that
is done instead of reallocation when existing free space is not enough

9d36032370 Implement QMetaType::canConvert() and use it in QVariant
Use the fact that we return the conversion function as a lambda
to find out reliably whether a conversion between two types
can be done.

This requires some minor adjustments to our tests:

* Nothing can convert to an unknown type and vice versa
* Adjust results to the fact that we don't convert from char
  to QString anymore (where the old method was incorrect)
* QStringList->QString requires some adjustments, as we only
  convert if the string list has exactly one element. For now
  we return true in canConvert(), but the conversion behavior
  in this case is something we should rethink, as it is very
  surprising.

1df02b5f98 Fix conversions to JSON from QVariant
After reimplementing Qt JSON support on top of CBOR, there were
unintended behavior changes when converting QVariant{, List, Map} to
QJson{Value, Array, List} due to reusing the code for converting
QVariant* types to CBOR types, and from CBOR types to corresponding JSON
types. In particular, conversions from QVariant containing QByteArray to
JSON has been affected: according to RFC 7049, when converting from
CBOR to JSON, raw byte array data must be encoded in base64url when
converting to a JSON string. As a result QVariant* types containing
QByteArray data ended up base64url-encoded when converted to JSON,
instead of converting using QString::fromUtf8() as before.

There were also differences when converting QRegularExpression.

Reverted the behavior changes by adding a flag to internal methods for
converting CBOR to JSON, to distinguish whether the conversion is done
from QVariant* or CBOR types. These methods now will fall back to the old
behavior, if the conversion is done using QJson*::fromVariant*().

Additionally fixed QJsonValue::fromVariant conversion for NaN and
infinities: they should always convert to QJsonValue::Null. This works
correctly when converting from variant to QJsonArray/QJsonObject, but has
been wrong for QJsonValue.

Added more tests to verify the expected behavior.

[ChangeLog][Important Behavior Changes] Restored pre-5.15.0 behavior
when converting from QVariant* to QJson* types. Unforeseen consequences
of changes in 5.15.0 caused QByteArray data to be base64url-encoded; the
handling of QRegularExpression was also unintentionally changed. These
conversions are now reverted to the prior behavior. Additionally fixed
QJsonValue::fromVariant conversions for NaN and infinities: they should
always convert to QJsonValue::Null.

isNull() would forward to the contained type and check that type's
isNull() method for some of the builtin types. Remove that behavior
and only return true in isNull(), if the variant is invalid, doesn't

In addition, implement more consistent behavior when constructing
a QVariant using the internal API taking a copy from a void *.
isNull() should return true in both cases. This mainly changes behavior
for some corner cases and when using our internal API.

[ChangeLog][Important Behavior Changes] QVariant::isNull()
no longer returns true when the variant contains an object of some
type with an isNull() method, that returns true for the object;
QVariant::isNull() now only returns true when the variant contains
no object or a null pointer.

will not compare equal, with two exceptions: If both types are numeric
types they will get compared according to C++ type promotion rules. If

from the string to the numeric tpye will be attempted.

92ee9bd6b8 CMake: Properly handle CONFIG += thread aka Threads::Threads
mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.

To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.

We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.

For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).

As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.

Receiving an rvalue still requires to check whether the parameter
is detached, otherwise we can't steal its backing std::map.

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.
