f51b690e91 Remove timeStep parameter from QAnimationDrive::advanceAnimation
Addresses ### Qt 6 comment, and documentation pointing out that the parameter
value is ignored. It wasn't ignored in the code, but that's the kind of change
we can make now.

With this change, QUnifiedTimer::updateAnimationTimers is only called with -1
as the currentTick input parameter, also from Qt Declarative. Make it default,
so that leaf modules can be fixed. Once that it done, the parameter can be
removed completely.

0e0149c64d Ignore weight in .ui files instead of converting it
In 3558704ed5, we added code to
support old .ui files which used the old integer scale for font
weights by checking for a special attribute which would help
separate new and old files.

Since then, it has become apparent that the weight element in
.ui is not actually used for anything, since it is only emitted
when the bold flag is set and always has to match QFont::Bold
in these cases.

So instead of converting, we simply ignore it now, and respect
the bold flag instead.

This also reverts the changes to ui4.* in uic, since the
scale attribute is no longer needed.

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.

QBindingStorage is a class that can store a set of binding objects

The binding storage has a pointer to the TLS entry containing the
currently evaluating binding. Like that we avoid repeated TLS
lookups and reduce the overhead of the property system to one
pointer lookup and one compare for the case that properties
aren't being used.

Each QObject now owns one binding storage object, that can be used to
store binding data for properties that members of the QObject.

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.

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).

Updated QPodArrayOps::reallocate to be aware of growing

rather close and similar to what Qt6 QList is doing when not
growing (e.g. reserve/squeeze)

Added initial QCommonArrayOps with helper function that tells
when reallocation is preferable over just using the insert-like
operation. This comes up later on when GrowsBackwards policy is
properly supported in operations

Essentially, 2/3 main data management blocks for prepend optimization
are introduced here. The last one being a generalized data move that
is done instead of reallocation when existing free space is not enough

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.

b5f972361a Introduce QWindow::paintEvent with QPA plumbing
The explicit paint event on QtGui and QPA level allows us to untangle
the expose event, which today has at least 3 different meanings.

It also allows us to follow the platform more closely in its semantics
of when painting can happen. On some platforms a paint can come in
before a window is exposed, e.g. to prepare the first frame. On others
a paint can come in after a window has been de-exposed, to save a
snapshot of the window for use in an application switcher or similar.

The expose keeps its semantics of being a barrier signaling that the
application can now render at will, for example in a threaded render
loop.

There are two compatibility code paths in this patch:

  1. For platform plugins that do not yet report the PaintEvents
     capability, QtGui will synthesize paint events on the platform's
     behalf, based on the existing expose events coming from the platform.

  2. For applications that do not yet implement paintEvent, QtGui will
     send expose events instead, ensuring the same behavior as before.

For now none of the platform plugins deliver paint events natively,
so the first compatibility code path is always active.

Second, make sure that if the target already exists that it is a

that belongs to another user, it can be changed to point to another
place, which we won't like.

And as a bonus, we're printing more information to the user in case
something went wrong. Sample outputs:

Implemented in a similar way as d1111632e2.

fb9ec8ad44 Move QFileSystemModel into QtGui
This requires a QAbstractFileIconProvider in QtGui, as the standard
QFileIconProvider depends on QStyle, and cannot be moved out of
QtWidgets.

QAbstractFileIconProvider returns strings for file types, but returns
no icons yet. Support for a default icon set might be added in a
follow-up commit.

556a7e7318 QIODevicePrivate: rearrange class members
As this class is a subject of the library hook data, there must be a
solid understanding of the member's alignment and padding across
different architectures. By reordering the layout, this patch provides
a clearer way of adding new members to the class.

Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.

When you bind more values than the query has placeholders,

38806273e5 Remove QEventPoint::event() in favor of device()
event()->device() was the most common use case anyway.

The idea that the "parent" of a QEventPoint is the QPointerEvent
interferes with the ability to copy and move event objects: the parent
pointers are dangling unless we use the QPointerEvent subclass
destructors to set the points' parents to null.  Since there is no move
constructor, even returning a QEventPoint from a function by value
results in destroying the temporary instance and copying it to the
caller's space.  So the parent pointer is often useless, unless we do
even more work to maintain it when the event moves.

If we optimize to avoid copying QEventPoints too much (and perhaps
enable exposing _mutable_ points to QML) by storing reusable instances in
QPointingDevice (which is the current plan), then the actual parent will
no longer be the event.  Events are usually stack-allocated, thus
temporary and intended to be movable.

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.

Add some special handling for long/ulong, as these types could be

through QDataStream.

[ChangeLog][QtCore][QMetaType] The QMetaType::registerStreamOperators()
and QMetaType::registerDebugStreamOperator() methods have been
removed. The streaming operators for a type are now automatically
registered together with the type registration.  This implies that the
operators should be visible wherever the type is visible and being used.

[ChangeLog][Behavior Incompatible Changes] Because the QDataStream and
QDebug serialization operators are automatically registered with
QMetaType, the declarations of those functions must be present at any
point where the type is used with QMetaType and QVariant.
