the QMetaType is represented as a pointer to a "vtable" in the form of
a QtPrivate::QMetaTypeInterface*
The recomanded use of QMetaType is to construct an object with
QMetaType::fromType. This does not require any registration.
There is still an id() function which will do some registration
for compatibility with Qt5. Also the patch does not really touch
the other extra things that can be registered (data stream operator,
comparison operator, iteratable, ...) and this still uses the previous
system.
This is only the change in QMetaType, other changes to use it in QVariant

Widgets have a default palette and font that is influenced by several
factors: theme, style, QApplication-wide overrides, and the parent's.
If an application sets a font or palette on a parent, then widgets
inherit those settings, no matter when they are added to the parent.
The bug is that this is not true for widgets that have an application-
wide override defined by the platform theme. For those, we need to merge
parent palette and font attributes with the theme, and this is currently
not done correctly, as the respective masks are not merged and inherited.
This change fixes this for fonts and palettes. Children are inheriting
their parent's inheritance masks, combined with the mask for the
attributes set explicitly on the parent. This makes the font and palette
resolving code correctly adopt those attributes that are set explicily,
while leaving everything else as per the theme override.
The test verifies that this works for children and grand children added
to a widget that has a palette or font set, both when themed and
unthemed. Children with own entries don't inherit from parent.
The QFont::resetFont test had to be changed, as it was testing the
wrong behavior. If the child would be added to the parent before the
font property was set, then the test would have failed. Since this
change makes sure that children inherit fonts in the same way, no
matter on when they are added to their parent, the test is now
modified to cover both cases, and ensures that they return identical
results.
[ChangeLog][QtWidgets][QWidget] Fonts and palette settings are inherited
by children from their parents even if the children have application-
wide platform theme overrides.

If a widget backed by a QWindow is moved we need to translate the window
geometry into a position relative to the parent widget. In most cases this
was incidentally working due to widgets backed by QWindows always having
QWindow parents too, so the QWindow position was applicable to the widget
as well. But when Qt::WA_DontCreateNativeAncestors is used this is no
longer the case, and we would end up with a widget geometry that included
the parent positions all the way up to the next native widget.
The updatePos() function has been squashed into handleMoveEvent(), since
we need to ensure the position in the move event sent to the widget is
correct as well.

The logic is now mostly handled in QGuiApplication, with QApplication
only dealing with the widget-specific palettes and interaction between
the style and the palette.
The application now picks up changes to the platform theme and will
re-resolve the current application palette appropriately. This also
works even if an explicit application palette has been set, in which
case any missing roles are filled in by the theme.
The palette can now also be reset back to the default application
palette that's fully based on the theme, by passing in the default
constructed palette (or any palette that doesn't have any roles set).
This is also correctly reflected in the Qt::AA_SetPalette attribute.
Conceptually this means QGuiApplication and QApplication follow the
same behavior as QWidget, where the palette falls back to a base or
inherited palette for roles that are not set, in this case the theme.
Behavior-wise this means that the default application palette of the
application does not have any roles set, but clients should not have
relied on this, nor does QWidget rely on that internally.
It also means that setting a palette on the application and then
getting it back again will not produce the same palette as set,
since the palette was resolved against the theme in the meantime.
This is the same behavior as for QWidget, and although it's a
behavior change it's one towards a more sane behavior, so we
accept it.
[ChangeLog] Application palettes are now resolved against the platform's
theme palette, the same way widget palettes are resolved against their
parents, and the application palette. This means the application palette
reflected through QGuiApplication::palette() may not be exactly the same
palette as set via QGuiApplication::setPalette().

We include WA_DontShowOnScreen so that widgets that are proxied via

There's still some divergence between closeAllWindows and the logic
in QApplication::event's quit handling, but aligning that requires
more work than this particular fix, and should probably also be

QObjectPrivate::threadData used to be a QThreadData *, and was
read and written from multiple threads without proper synchronization.
As an example, it was read from QCoreApplication::postEvent and
written from QObject::moveToThread, therefore causing UB.
Port threadData to a proper atomic, removing the races. Fix all usage
points.
In general, QObject is documented to be simply reentrant,
not thread-safe, and certain bits (e.g. timers, moveToThread)
are not even reentrant. The reasoning therefore is that a given
QObject's threadData is not supposed to be touched by multiple
threads without some synchronization happening elsewhere, and
therefore relaxed loads should be sufficient.
As drive-by change: refactor QCoreApplication::postEvent.
It was particularly subtle, because it had a loop using a volatile
to cope with the possibility of the receiver object switching thread
while we tried to lock its thread's event queue.
However, volatile does not achieve any synchronization, so drop it,
and refactor the algorithm using better locking primitives.
Put this algorithm in a common place, and also reuse it from
removePostedEvents, which was lacking any synchronization.

Simply moving QAction to QtGui was not deemed possible since
it operates on a set of controls of some kind. The approach to
extract a base class was taken instead, named QGuiAction
following the QGuiApplication scheme. QAction remains in
widgets, but changes base class.
For QActionGroup, the functions addAction(text/icon), which
create an action, cannot be implemented in QtGui, hence a base
class is needed, too (unless they are deprecated and removed).

Instead of having each platform plugin deal with application termination
in their own weird ways, we now have a QPA API to signal that the system
requested the application to terminate.
On the QGuiApplication side this results in a Quit event being sent to
the application, which triggers the default behavior of closing all app
windows, and then finally calling QCoreApplication::quit().
The quit event replaces the misuse of a close event being sent to the
application. Close events are documented as being sent to windows.
The close events that are sent to individual windows as part of the
quit process can be ignored. This will skip the final quit() of
the application, and also inform the platform that the quit was
not accepted, in case that should be propagated further.
In the future the logic for closing windows should be unified
between the various approaches in closeAllWindows, shouldQuit,
and friends.

this complicated the code quite a bit.
Aggregate by value instead (it's just one of three such vectors now).
Drive-by fixes:
- use QVector::removeAll() instead of rolling your own
- port two indexed loops to ranged ones. In the first case, it's safe,
as the loop body clearly doesn't touch the iteratee (it's just a
std::accumulate). In the second, the question no longer applies, as

QApplicationPrivate::focus_widget became a dangling pointer
in the following scenario:
A widget first gets focus and later on gets a focus proxy.
QApplicationPrivate::focus_widget was still pointing to the initial widget.
Upon destruction, QWidget::hasFocus() [which follows to the focus proxy
and then compares with focus_widget] was therefore false for both
widgets. So QWidget::clearFocus() didn't call
QApplicationPrivate::setFocusWidget(0) for either of them. As a
result, focus_widget remained set, and became dangling.
In real life, this happened with a QWebEngineView, which the application
gave focus to upon creation. At that time it doesn't have a focus proxy
yet. That happens later, in QWebEngineViewPrivate::widgetChanged.

This is to support rare setups involving an X11 server with multiple
independent displays ("zaphod heads" on which the DISPLAY env var
is different), possibly with multiple outputs forming a virtual desktop
on each display.
QMenu::popup() has been assuming that it should show on the screen where
the mouse cursor is. That's good most of the time; but with multiple
independent screens, QGuiApplication::screenAt(pos) cannot tell us which
screen to use (it's ambiguous), but rather will choose the first screen
that _could_ contain that position (as documented). In the example in
QTBUG-76162, the QMenu has been constructed with a QDesktopScreenWidget
as its parent specifically for the purpose of telling it which screen to
pop up on; so we need to respect that. But QWidgetPrivate::init() sets
the QObject::parent() to null (because the widget isn't actually shown
as a child of the QDesktopScreenWidget), and QWidgetPrivate::create_sys()
sets initialScreenIndex back to -1 to provide freedom to change the
screen later; so QMenu has to remember the screen index for itself.
QMenuBarPrivate::popupAction() searches the siblings of the screen on
which the menubar is claiming to be (rather than all screens on all
displays), to find the screen containing the point at the middle of the
bottom edge of the clicked menubar item. It then sets initialScreenIndex
so that QMenu::popup() will respect it rather than trying to decide for
itself.
