Instead of plumbing QWidgetWindow close events via handleCloseEvent,
we just implement closeEvent directly. This allows QWindow do save
the state of the window/widget before the close event, so that we
know whether we should trigger lastWindowClosed handling, even if
the window was deleted as a result of the close event.
This also relieves QGuiApplication and QApplication from dealing
with the close logic in their notify functions, so that these
functions can focus on the propagation of events -- not how the
event is handled.

Although the two features are similar (automatic quit under certain

we actually expose them as a single property (automaticQuit e.g.)
The logic for determining whether we can can quit automatically has
been refactored to take both properties into account, on both a Core

Whenever a window was closed, we had logic to check if it was the last
window, and if so emitted lastWindowClosed and then tried to quit the
application. But the automatic quit process also checked if there were
any remaining windows, as this process could be triggered as a result
of a QEventLoopLocker going out of scope. The two paths now share the
same logic for determining if there are any remaining windows.
The docs have been updated to reflect the original intent of the logic,
dealing only with primary windows (top levels without a transient parent).
This was how both the original code paths implemented their logic.
For historical reasons the Qt::WA_QuitOnClose attribute is closely
tied to the lastWindowClosed signal, and isn't merely limited to
controlling whether we try an automatic quit when the last window
closes. For now this behavior has been kept, but the docs have been
updated to clarify how the attribute is handled in practice.

Resize QPlatformWindow on DPI change, so that QWindow
size can stay approximately constant.
For example, a 100x100 QWindow at 100% scaling will

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

Raw pointers are, of course, a no-no in modern code. In particular,

make_shared or QSharedPointer::create() should be used to reduce

Since this is private API, we're free to use std::shared_ptr, which

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

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.

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.

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).

When QWidgetWindow handles a QTouchEvent, it will call

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

XDG_SESSION_TYPE is a non-standard part of systemd, and not set if you
run a compositor from the command line, for instance.
[ChangeLog][Wayland] XDG_SESSION_TYPE is no longer used to determine which
platform plugin to use. Instead, if WAYLAND_DISPLAY is set in the environment,
wayland is used. Similarly, if DISPLAY is set, xcb is used. If both are
detected, wayland will be attempted first, then xcb.
Gnome-shell is still skipped for automatic wayland detection.

Omitting stationary points from touch events is such a marginal
optimization that this code probably isn't worth maintaining.
It wasn't implemented correctly this time either, according to the
tst_QQuickMultiPointTouchArea::stationaryTouchWithChangingPressure()
test.
[ChangeLog][QtGui][QPointerEvent] We no longer attempt to avoid
delivery of stationary points within QTouchEvent: every pressed point
is now included in every TouchUpdate event.

In 4e400369c0 we began to send synth-mouse
events from the touch device, but in the opposite direction it was not
consistent.
Add autotests to prove that it's consistent both ways now.

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.
