In order to fix QTBUG-95552 properly we have to add APIs to
QGraphicsSceneWheelEvent that informs QGraphicsProxyWidget about
whether the event is a high-precision event where Qt grabs the
wheel.
If it is, then the wheel grabber will be the QGraphicsView's viewport,
and any wheel event sent to any widget will be grabbed by it. This
results in infinite recoursion, partly fixed in change
I78400ceae8da7a4e22a988c06ed58f99f1a979f4.
The proper fix is to re-grab the wheel by the embedded widget
if it (or any of its children) accepts the ScrollBegin event (and if
not, return the grab to the QGraphicsView).
This fixes the scenarios that failed in the test case, so now scrolling
through nested widgets and scrolling in nested widgets works as the
user would expect.

For high-precision wheel scrolling sequences, the widget that gets
the first (typically ScrollBegin) event grabs the wheel. Qt directs
all future wheel events within the same sequence (i.e. until ScrollEnd)
to that widget.
QGraphicsView passes wheel events through to the item under the mouse,
and QGraphicsProxyWidget implements wheelEvent to forward a synthesized
QWheelEvent to the embedded widget. Since QGraphicsView's viewport has
already grabbed the wheel, any forwarded event would end up back in
QGraphicsView, resulting in infinite recursion (if the assert doesn't
fail first in debug builds).
The correct fix requires that QGraphicsProxyWidget knows that this is
a high-precision wheel event, allowing it to adjust the wheel grabber
temporarily to the embedded widget. However, QGraphicsSceneWheelEvent
doesn't provide this information.
To fix the infinite recursion, mark the generated event as synthesized
by Qt (but still send it spontaneously to enable propagarion within
the proxy widget hierarchy). In QApplication's notification routine,
interpret such events then to override the wheel grabber.
Add a test case for the various scenarios. This 6.1 compatible fix
does not pass all situations. A follow up commit that introduces the
missing APIs to QGraphicsSceneWheelEvent then fixes those as well.

Input events in Qt are accepted when constructed, and ignored by the
default event handler (so overriding the event handler is enough to
accept an event).
Since we use the same QWheelEvent instance for each propagation step,
we need to reset the event to be accepted before each delivery so that
an earlier child ignoring the event doesn't result in the event being
ignored without explicit acceptance.

The plan for QObject::connect() (perfect) forwarders, such as
QWidget::addAction(), was to just use a variant of the Detection Idiom
to see whether QObject::connect() with the arguments as given would
compile and SFINAE out the forwarder otherwise.
It turns out that the "functor" overload of QObject::connect(), in
particular, is severly underconstrained and accepts e.g. QKeySequence
as a function object, only erroring out via a static_assert() in the
body of the function, and thus at instantiation time and not, as
needed, at overload resolution time.
At the same time, we don't really want QObject::connect() to SFINAE
out on argument mismatches between signal and slot, because the
resulting error messages would be ... unkind to users of the API. We
would like to keep the static_assert()s for easier error reporting.
Reconciling these two contradicting requirements has so far eluded
this author, so for now, to unblock progress, we explicitly black-
and, in one case, white-list possible arguments. Because QKeySequence,
in particular, is implicitly constructible from int(!), and therefore
any enum type(!), incl. Qt::ConnectionType, we need to do way too much
coding in the addAction() constraints. Hopefully, we'll be able to fix
the issue at the root cause, in QObject, before Qt 6.3 is out, but
until then, this is an ok-ish stop-gap measure.
Add thorough overload set checks (positive ones only, for now) to

Changing anything on a QWindow's QSurfaceFormat has zero and null
effects once the underlying native window has been created. Letting
QWidget update the format is wrong in this case, because we always
expect that the value returned from QWindow::format() reflects
reality.
(reality being the settings with which the underlying native resource
was created, which is typically frozen after QWindow::create(), not
the state of some QWidget attribute. There are certain exceptions to
this, such as when preparing to recreate the underlying native window,
in which case one will want to update all relevant fields of the
format based on the current values of the widget attributes, which is
exactly what QWidgetPrivate::create() implements, and that's good.)
Such a mismatch can have fatal consequences when OpenGL and friends
are involved, but this always depends heavily on the platform and
windowing system. For example, claiming that the alpha buffer size is
0 when the native window was created with 8, or vice versa, can break
OpenGL-related code (both in Qt itself and in applications), that
tries to create a QOpengGLContext configured based on what
QWindow::format() returns. If that format describes settings that are
incompatible with the actual underlying native window, we end up with
the classic Invalid pixel format, EGL_BAD_MATCH, and alike errors.
This is exactly what is happening when a QOpenGLWidget (or
QQuickWidget) is placed in a QDockWidget where one of the ancestors is
forced to native (winId() was called or WA_NativeWindow was set). When
undocking, various code paths in QWidget will try to update the opaque
flag of the widget, which in turn calls updateIsTranslucent. Now, if
this function unconditionally changes the alphaBufferSize in the
QWindow's QSurfaceFormat (even though this is completely futile to do,
it has no visible effect in practice), we get the problem described
above: rendering breaking down due to OpenGL contexts created with a
pixel format incompatible with the native window.
Prevent all this by not touching the format once the QWindow has a
QPlatformWindow. This is the right thing to do, regardless of the bug
in question: a window's (or context's or any other native resource
wrapping class's) format must describe the underlying native resource
and must never deviate, unless we are preparing to create a new native
resource underneath.
When it comes to the autotest, this changes the test added in
555661b625c40f21a6a3e4c73e928a6e8a46db20: the autotest logic is
inverted because what we should test for is that the QSurfaceFormat
stays untouched once the application makes a - futile - attribute
change on the widget.

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.

setTabOrder was not considering the case, when a child widget has
its focus proxy set to its parent widget. This happens, for example,
for the QLineEdit that is nested inside the QAbstractSpinBox.
For such cases the lastFocusChild was calculated incorrectly, and, as
a result, such child widgets were not correctly positioned in the
focus chain. This could lead to an error while backtabbing.
Here is a brief example. Suppose we have 3 widgets arranged like this:
auto spinBoxOne = new QDoubleSpinBox;
auto spinBoxTwo = new QDoubleSpinBox;
auto button = new QPushButton;
Then the default widget focus order is:
- spinBoxOne
- lineedit (from spinBoxOne)
- spinBoxTwo
- lineedit (from spinBoxTwo)
- button
Before this commit setting the explicit tab order changed the focus
order in the following way:
QWidget::setTabOrder(spinBoxOne, spinBoxTwo);
QWidget::setTabOrder(spinBoxTwo, button);
- spinBoxOne
- spinBoxTwo
- button
- lineedit (from spinBoxOne)
- lineedit (from spinBoxTwo)
In this case, backtabbing from spinBoxOne actually leads us to
lineedit (from spinBoxTwo), which refers to spinBoxTwo.
And so we're stuck in a loop.
This commit fixes the issue by handling such special case, and
preserving correct focus order.
Note: the actual unit-test in this patch uses QLineEdit instead of
QPushButton, because one can't tab to buttons on macOS by default.
However the general idea is the same.

We do not unconditionally clear focus_child like the existing comment
said. We only do it if the focus_child was the widget that is clearing
focus. So in many cases we'll end up with the same focus object as
before. We can not report that as a focusObjectChanged to the window,
as that will potentially trigger a reset or cancel of the current
input method for the (unchanged) focus object.
Fixes: QTBUG-86976
Pick-to: 5.15

This allows for potential optimizations in widgets, e.g. no need to for the
input method to query all data when only the cursor position changed.

Prevent recursion: hideTipImmediately() calls QWidget::close(),
which will soon start calling QWindow::close(), which
will send another close event.
Fix this by calling hideTipImmediately() only for Close
events not targeted for the tip label.

Not used anywhere in Qt 6, and if whatever needs this ever comes back,
then we won't implement it like this.
