The functionality now lives in QGuiApplication, and is triggered
by QGuiApplication and QApplication after dispatching the close
event to the window.
The slight difference between how a Qt GUI and Qt Widget app
determines if a window should contribute to the close-on-quit
behavior has been abstracted into a QWindowPrivate helper.
The additional checks that were in place for skipping out of
the whole maybeQuitOnLastWindowClosed machinery have been kept.

The {mouse,touch}DoubleXDistance variables were initialized to -1,
which forces them into the DATA segments.
But this value is completely unused, since these variables are also
set in initThemeHints(), called from QGuiApplicationPrivate::init(),
before their only user, QGuiApplicationPrivate::processMouseEvent(),
can possibly execute.
By changing the default value to 0, then, we allow the compiler to
place these variables into the BSS segment.

The major use-case of the now private QX11Info from Qt X11 Extras was
getting hold of the Xlib display and XCB connection, for example in KDE:
https://lxr.kde.org/search?%21v=kf5-qt5&_filestring=&_string=QX11Info
A new native interface for QGuiApplication has now been added that
exposes these two properties, e.g.:
if (auto *x11App = app.nativeInterface<QX11Application>())
qDebug() << x11App->display() << x11App->connection();
To avoid type clashes one of the enum values of QXcbNativeInterface's
ResourceType had to be renamed.

Resize QPlatformWindow on DPI change, so that QWindow
size can stay approximately constant.
For example, a 100x100 QWindow at 100% scaling will
have a 100x100 QPlatformWindow. If the scaling is changed
to 200% then the QPlatformWindow is resized to 200x200,
while the size of the QWindow stays at at 100x100.
In practice the QWindow size will also change slightly,
due to inaccuracies in how we adjust for the size of the
non-client window area. This will be addressed in a later commit.
We can get DPI change independently of screen change,
so no resizing should happen in screen change events.
Disable the resize code in QGuiApplication for Q_OS_WIN,
and remove the WithinDpiChanged flag.
The new flow for handling DPI change is:
1) Send screen change (if any), so that the correct
screen will be used when calculating scale factors
during the following resize.
2) Resize the native window, which will trigger geometry
change events, possibly also for the QWindow.
3) Resize child windows; WM_DPICHANGED is sent to
top-level windows only.

The use of a freestanding function is not needed now that the name
doesn't alias the nativeInterface accessor function, and was just
adding complexity to the machinery.

In QPanGesture this is called delta().
OTOH we have QWheelEvent::pixelDeltas().
Delta is a vector, and there's only one (with two components).
Native gestures hold incremental values: e.g. the pinch gesture event
provides an incremental amount of either zooming or rotation (so most
events have QNativeGestureEvent::value() very close to 0).
It's the same with the pan gesture's delta().
Add better docs for swipe and pan gestures.

... instead of raw pointers or QSharedPointer.
Raw pointers are, of course, a no-no in modern code. In particular,
when the result is then held in shared_ptr or QSharedPointer,
make_shared or QSharedPointer::create() should be used to reduce
number of memory allocations.
Since this is private API, we're free to use std::shared_ptr, which
does only half the atomic operations on copies, compared to
QSharedPointer, so is more efficient.
For either make_shared or QSharedPointer::create(), we need to work
around the private ctor, which we do by inheriting a member-function
local class from QColorTrcLut and make_shared'ing that. As a
member-function-local class, it has access to the otherwise private
parts of QColorTrcLut, including its default constructor. As a public
subclass, shared_ptr has no problem performing the derived-to-base
pointer adjustment in the return statement. This way, we can use
make_shared even though our target's class' ctor is private.

Following the discussion in QTBUG-69452, the resulting change in
cc33dd079796437bafed8f42de7fbf8f17d19ec8, and the documentation of
QAction::shortcutVisibleInContextMenu, the intention is that the
attribute allows the overriding of the platform default.
However, QAction did ask both the attribute and the platform
integration, making the override impossible. Instead, ask only
the attribute, but default the value of the attribute to what the
platform integration provides.
[ChangeLog][QtGui][QAction] The shortcutVisibleInContextMenu property
defaults to the value of the Qt::AA_DontShowShortcutsInContextMenus
attribute, which in turn defaults to the platform integration. To
override the default, set the application attribute after
instantiating QApplication, or override the default for each
QAction instance.

A previous change to fix QTBUG-85431 has caused this issue by emulating
the behavior of the non-enhanced mouse event handler in a particular
case, where mouse move events that did not change position were ignored.
However, some of these events seem to be involved in the dock drag&drop
implementation. This issue is also reproduced in pre-5.15 releases,
predating the QTBUG-85431 fix, by disabling the enhanced mouse event
handler by setting the QT_QPA_DISABLE_ENHANCED_MOUSE env var. However,
the ignored events in the current issue seem to be non-client events
only, while the QTBUG-85431 issue was related to client mouse events.
So we can restrict the test added in the QTBUG-85431 fix and have both
issues fixed.

The initial approach for providing public access to native
interfaces via T::nativeInteface<I>() was based on the template
not being defined, and then having explicit instantiations of
the supported types in a source file, so that the accessors
were exported and available to the user.
This worked fine for "simple" types such as QOpenGLContext
and QOffscreenSurface, but presented a problem in the context
of classes with subclasses, such as Q{Core,Gui}Application.
To ensure that a native interface for QCoreApplication was
accessible both from QCoreApplication and its subclasses,
while at the same time preventing a native interface for
QGuiApplication to be accessible for QCoreApplication, the
nativeInterface() template function had to be declared in
each subclass. Which in turn meant specializing each native
interface once for each subclass it was available in.
This quickly became tedious to manage, and the requirements
for exposing a new native interface wasn't very clear with
all these template specializations and explicit instantiations
spread around.
To improve on this situation, while also squashing a few
other birds at the same time, we change the approach to
use type erasure. The definition of T::nativeInteface<I>()
is now inline, passing on the requested interface to a per
type (T, not I) helper function, with the interface type
flattened to a std::type_info.
The type_info requested by the user is then compared to the
available types in a single per-type (T) "switch statement",
which is a lot easier to follow for someone trying to trace
the logic of how a native interface is resolved.
We can safely rely on type_info being stable between the user
application and the Qt library as a result of exporting the
type info for each native interface, by explicitly ensuring
they have a key function. This is the same mechanism that
ensures we can safely dynamic_cast these interfaces, even
across library boundaries.
The use of a free standing templated helper function instead
of a member function in the type T, is to avoid shadowing issues,
and to not pollute the class namespace of T with the helper
function.
Since we are already changing the plumbing for how a user
resolves a native interface for a type T, we take the opportunity
to add a few extra safeguards to the machinery.
First, we add a static assert in the T::nativeInteface<I>()
definition, that ensures that only compatible interfaces,
as declared by the interface themselves, are allowed.
This ensures a compile time error when an incompatible
interface is requested, which improves on the link time
errors we had prior to this patch, and also offsets the
one downside of type erasure, namely that errors are only
caught at runtime.
Secondly, each interface meant for public consumption through
T::nativeInteface<I>() is declared with a revision, which
is checked when requesting the interface. This allows us
to bump the revision when we make breaking changes to the
interface that would have otherwise been binary incompatible.
Since the user will never see this interface due to the
revision check, they will not end up calling methods that
have been removed or renamed.
One advantage of moving to a type-erased approach for the
plumbing is that we're not longer exposing the native
interface types as part of the T::nativeInteface symbols.
This means that if we ever want to rename a native interface,
the only exported symbol that the user code relies on is
the type info. Renaming is then possible by just exporting
the type info for the old interface, but leaving it empty.
Since no class in Qt implements the old native interface,
the user will just get a nullptr back, similarly to bumping
the revision of an interface.

QHighDpiScaling has two init/update functions:
- initHighDpiScaling(): called once during QGuiApplication construction
- updateHighDpiScaling(): called whenever (relevant) screen configuration changes
Currently the calls to updateHighDpiScaling() are made from
multiple places including platform code. Simplify by calling
it from two locations:
- QWindowSystemInterface::handleScreenAdded()
- QGuiApplicationPrivate::processScreenLogicalDotsPerInchChange()
Replace comment about early calls to qt_defaultDpi with a
test which calls qt_defaultDpiX/Y with no screens attached.
(Looking at the qt_defaultDpiX() implementation, it is unlikely
that there will be a problem as long as updateHighDpiScaling()
is called before QGuiApplication::primaryScreen() starts returning
a non-null value.)

It's not clear now whether trackpad gestures on Windows will need to be
so different than on macOS; however, any reasonable int value can be
stored in a qreal, and in Qt Quick we like to use floating-point numbers
for all "real" values and measurements. So since we need to add more
storage, and quint64 m_intValue has never been used, we now replace it
with a QVector2D, which should have the same size. The intended use
is that PanNativeGesture will include a displacement, probably in
pixels, by which the viewport or some target item should be panned or
moved. The naming of deltas() is flexible enough to support any gesture
with some incremental 2D valuators, though, just as value() has
gesture-dependent semantics.
fingerCount() will be useful for Qt Quick pointer handlers to filter
out events that have the wrong number of fingers, e.g. to require that
either a 3-finger pan gesture or 3 individual touchpoints are required
to activate DragHandler { minimumPointCount: 3 } (assuming we implement
pan gesture support in DragHandler).

On Gnome, we will not default to Wayland at the moment, even
if the desktop is run in Wayland mode. In this case, we warn
users that they can still select Wayland manually using
QT_QPA_PLATFORM.
Problem was: We never checked if they had actually explicitly
selected Wayland, so even in the cases where we would end up
using that QPA plugin, people would still see the warning.
This moves the check to the end of the platform selection
algorithm, after we have collected all the information.

mouse events
When QWidgetWindow handles a QTouchEvent, it will call
updateTouchPointsForWidget() for each widget it tries
to deliver the touch event to. This will make sure that
the point's position() is updated to be local to the
widget being processed.
The problem is that we never reset this overwriting of
local positions in the event after we're done. So if we
later try to synthesize a mouse event from it, the local
position in the fake mouse event will be based on the local
position inside a random widget, and not the original local
position sent from QPA.
Rather than trying to store all the original local
positions inside the event before going through this delivery
logic, and reset it afterwards, we base the local position of
the synthesized mouse event on the (unmodified) global
position instead.

QGuiApplicationPrivate::processMouseEvent() sends a
QWindowSystemInterfacePrivate::TouchEvent if the mouse event is not
accepted and AA_SynthesizeTouchForUnhandledMouseEvents is enabled.
A QPA TouchEvent always contains native touch points, which is why
it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to
translate the QMouseEvent's device-independent position back to the
raw position that it would have had if it came from a real touchscreen.
Therefore we must give that function touchpoints that are actually in
native coordinates.
It may be that some of this transformation could be avoided entirely,
but here we prove that the existing way works correctly, by adding
coordinate checking to the tst_QWindow::mouseToTouchTranslation() test.

requested a window-system mouse grab. It's better to assume that any
residual velocity stored in the persistent QEventPoint instance (in
QPointingDevicePrivate::activePoints) is inaccurate, and just start over
from zero. Especially for the sake of autotest sanity.

The mouse event that is sent to QPlatformCursor is in native pixels,
but the QSinglePointEvent constructor sets QEventPoint::globalLastPosition
every time, and velocity is calculated by delta from globalLastPosition
to globalPosition. We plan to rely on this velocity being correct
in Qt Quick, in Flickable for example. So globalLastPosition and
globalPosition need to be in the same coordinate system at the time
QPointerEvent::setTimestamp() is called.

During delivery of a TouchBegin event, if no widget accepts it,
we begin treating the first touchpoint as a synth-mouse, as before.
If a second touchpoint is pressed or released in any order, it's
irrelevant: the fake mouse button is released as soon as the first
touchpoint is released. This fixes the bug that such a scenario
caused the mouse release not to be sent, so that a widget could get
"stuck" in pressed state.

QQuickEventPoint instances were very long-lived and got reused from one
event to the next. That was initially done because they were "heavy"
QObjects; but it also became useful to store state in them between
events. But this is in conflict with the ubiquitous event replay
code that assumes it's OK to hold an event instance (especially
a QMouseEvent) for any length of time, and then send it to some widget,
item or window. Clearly QEventPoints must be stored in the QPointerEvent,
if we are to avoid the need for workarounds to keep such old code working.
And now they have d-pointers, so copying is cheap. But replay code
will need to detach() their QEventPoints now.
QEventPoint is useful as an object to hold state, but we now store
the truly persistent state separately in an EventPointData struct,
in QPointingDevicePrivate::activePoints. Incoming events merely
update the persistent points, then we deliver those instead.
Thus when event handler code modifies state, it will be remembered
even when the delivery is done and the QPA event is destroyed.
This gets us a step closer to supporting multiple simultaneous mice.
Within pointer events, the points are moved up to QPointerEvent itself:
QList<QEventPoint> m_points;
This means pointCount(), point(int i) and points() can be non-virtual.
However in any QSinglePointEvent, the list only contains one point.
We hope that pessimization is worthwhile for the sake of removing
virtual functions, simplifying code in event classes themselves, and
enabling the use of the range-for loop over points() with any kind of
QPointerEvent, not just QTouchEvent. points() is a nicer API for the
sake of range-for looping; but point() is more suited to being
non-const.
In QML it's expected to be OK to emit a signal with a QPointerEvent
by value: that will involve copying the event. But QEventPoint
instances are explicitly shared, so calling setAccepted() modifies
the instance in activePoints (EventPointData.eventPoint.d->accept);
and the grabbers are stored separately and thus preserved between events.
In code such as MouseArea { onPressed: mouse.accepted = false }
we can either continue to emit the QQuickMouseEvent wrapper
or perhaps QEvent::setAccepted() could become virtual and set
the eventpoint's accepted flag instead, so that it will survive
after the event copy that QML sees is discarded.
The grabChanged() signal is useful to keep QQuickWindow informed
when items or handlers change exclusive or passive grabbers.
When a release happens at a different location than the last move event,
Qt synthesizes an additional move. But it would be "boring" if
QEventPoint::lastXPosition() accessors in any released eventpoint always
returned the same as the current QEventPoint::xPosition()s just because
of that; and it would mean that the velocity() must always be zero on
release, which would make it hard to use the final velocity to drive an
animation. So now we expect the lastPositions to be different than
current positions in a released eventpoint.
De-inline some functions whose implementations might be subject to
change later on. Improve documentation.
Since we have an accessor for pressTimestamp(), we might as well add one for
timestamp() too. That way users get enough information to calculate
instantaneous velocity, since the plan is for velocity() to be somewhat
smoothed.

If we have a platform plugin we ask the platform to quit, and if
not we fall back to the base implementation of QCoreApplication
that sends Quit events directly.
This allows the platform to involve the rest of the system in the
process. The platform will then come back with a spontaneous quit
via QWSI::handleApplicationTermination(), which will then send
the corresponding Quit even from QGuiApplication like normal.

With the Qt6 compatibility break, it can finally be removed.
Closing windows (which might quit the application with
quitOnLastWindowClosed() true, the default) acted contrary to the
documentation of the commitDataRequest() signal, which could have
been a hint.
This removes the workaround API from the fix for QTBUG-49667 and
also removes the problematic feature that it worked around.

Set HighDpiScaleFactorRoundingPolicy to PassThough
by default. This makes Qt track the system UI setting
accurately, and is overall the least confusing option.
Historically, Qt has rounded the scale factor (for example,
Windows 175% -> DPR 2) due to faulty handling of fractional
scale factors in Qt Widgets and with the native Windows
style.
Other areas of Qt such as Qt Quick have had few issues
with fractional scale factors and support this well.
Qt has never rounded the scale factor on the Android
platform.
Support for fractional scale factors in Qt Widgets and
the windows style has improved, which makes changing
the default for Qt 6 viable.

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.

Having three methods with the same name doing different things is
unnecessarily confusing, so follow the standard naming convention in
Qt and call the getter of the resolve mask resolveMask, and the setter
setResolveMask. These methods were all documented as internal.
The publicly documented resolve() method that merges two fonts and
palettes based on the respective masks remains as it is, even though
'merge' would perhaps be a better name.

QtQuickTest synthetized events can have modifiers, but those modifiers
were not accessible globally, from QGuiApplication::keyboardModifiers
for instance.
eg. calling QML's TestCase::mouseClick with modifiers triggering a call
to QGuiApplication::keyboardModifiers did not give the expected result.
QtTest synthesised events can also have modifiers and those were
correctly handled by QApplication to set modifiers globally.
This fix moves the handling code from QApplication::notify to
QGuiApplicationPrivate::maybeSimulateModifiers and calls this function
from QGuiApplication::notify too.
The definite fix would be to do as suggested in the comment attached to
the moved code:
> Qt Test should not call qapp->notify(), but rather route the events
> through the proper QPA interface. This is required to properly
> generate all other events such as enter/leave etc.
