Bridge QAccessibleSelectionInterface that was introduced
in commit 9d16d5e224 to
UIA's ISelectionProvider and ISelectionProvider2 interfaces
by extending the existing WindowsUiaSelectionProvider
to make use of the QAccessibleSelectionInterface.
Also make use of that interface to implement handling
for the ISelectionProviderItem interface methods when
an object has a parent that implements the
QAccessibleSelectionInterface.
Sample use from NVDA's Python console [1] with this
commit in place:
1) start NVDA
2) run the interview example (examples\widgets\itemviews\interview\interview.exe)
3) select "Item 1:0", "Item 2:0" and "Item 3:0" by left-clicking
on "Item 1:0" in the left view, then shift+clicking on "Item 3:0".
4) press Numpad_insert+control+z to start the NVDA Python console and
capture snapshot variables
5) query and use the interfaces using NVDA's Python console:
>>> import UIAHandler
>>> selectionpattern2 = focus.parent.UIAElement.GetCurrentPattern(10034).QueryInterface(UIAHandler.IUIAutomationSelectionPattern2)
>>> selectionpattern2.CurrentFirstSelectedItem.CurrentName

0
>>> selectionitempattern.CurrentIsSelected
0
>>> selectionpattern2.CurrentItemCount
2
>>> selectionitempattern.Select()
0
>>> selectionitempattern.CurrentIsSelected
1
(Note that calling selectionitempattern.AddToSelection
in that example would also unselect all other currently
selected entries, because the underlying implementation
has a selection mode of QAbstractItemView::SingleSelection
set in QAccessibleTree::selectRow, which gets called
from QAccessibleTable::select via QAccessibleTableCell::selectCell.)

When converting from an array to a map, we double the number of
elements, spread the old elements out to make one free slot of space
in front of each, and then place Integer values counting from 0 into
the free slots.
The old code contained a loop that would add a strong reference to the
original elements that happen to be containers and thus are
ref-counted in the first place. But this additional strong reference
is not needed: In both cases, detached or in-place, the detach() call
that ensured unique ownership of 'map/dst' will have either directly
or indirectly updated the ref-counts of the elements correctly, and
the following loops just reshuffle the elements in the QList, they
don't create new copies (QtCbor::Elements doesn't by itself manipulate
container->ref, but even if it did, the copy would have increased, and
the assignment of the Integers would have decreased, the ref-count
again). Adding the strong ref without a user then caused the container
members to be leaked.
Fix by removing the loop.

QWidget re-uses backing stores created in QWidgetPrivate::create().
The Android platform plugin creates a new platform window, when a
widget becomes a toplevel window. When it is hidden, the platform
window is deleted. The link between QAndroidPlatformWindow and its
backing store is made in the constructor of
QAndroidPlatformBackingstore. When a new QAndroidPlatformWindow is
constructed and the backing store is re-used, there is no more link
between platform window and platform backing store.
This has lead to screen assets not being painted, when shown more than
once.
This patch forces QWidgetPrivate::create() to construct a new backing
store on Android. This way, toplevel windows always have a backing
store associated with it. It adds an assertion to
QAndroidPlatformScreen::addWindow(). That will make e.g.
tst_QWidget::visible() crash without the fix.

In C++20 std::basic_string_view has gained a range constructor (like
QStringView always had), but that range constructor has been made
explicit. This means we can't just pass a QString(View) to a function
taking a u16string_view. The consensus seems to be that that types that
should implictly convert towards stdlib's string views should do that
via implicit conversion operators. This patch adds them for
* QByteArrayView => std::string_view
* QString(View) => std::u16string_view
* QUtf8StringView => std::string_view or std::u8string_view, depending
on the storage_type
QLatin1StringView doesn't have a matching std:: view so I'm not enabling
its conversion.
QByteArray poses a challenge, in that it already defines a conversion
towards const char *. (One can disable that conversion with a macro.)
That conversion makes it impossible to support:
QByteArray ba;
std::string_view sv1(ba); // 1
std::string_view sv2 = ba; // 2
because:
* if only operator const char *() is defined, then (2) doesn't work
(situation right now);
* if both conversions to const char * and string_view are defined, then
(1) is ambiguous on certain compilers (MSVC, QCC). Interestingly
enough, not on GCC/Clang, but only in C++17 and later modes.
I can't kill the conversion towards const char * (API break, and we use
it *everywhere* in Qt), hence, QByteArray does not get the implicit
conversion, at least not in this patch.

The old code violated the following principles:
- DRY: the same code occurred 3× in the code-base
- SCARY: the vast majority doesn't actually depend on template
arguments, causing template bloat
Solve both with a tiered Extract Method.
We cannot change the order of the operations performed on
QBasicFutureWatcher, in particular not the connect() to the
contination w.r.t. setFuture(), so we cannot leave the connect to the
continuation lambda outside the function, as it would mean to also
leave the setFuture() call outside.
Thanks to Volker's makeCallableObject(), we can, however, type-erase
the lambda using QSlotObjectBase, which is what connect() internally
creates, anyway, therefore bringing the whole function behind the ABI
boundary.
As a non-QObject, non-QMetaObject friend, we're lacking support for
actually doing something useful with a QSlotObjectBase, but that can
be fixed in the implementation now. The interface is stable, which is
what matters for 6.6 now.
This will allow a subsequent commit to drag QBasicFutureWatcher behind
the ABI boundary, unexporting it.
Saves a whopping 8KiB in tst_qfuture text size on optimized C++20
Linux AMD64 GCC9 builds.
Pick-to: 6.6

Extract Method non-template customConstructSharedImpl() to avoid
instantiating std::unique_ptr with a different per-F Deleter over and
over again.
Not picking to 6.5 because the function was confined to the
qvariant.cpp TU in those versions.
Cf. 11791e2a50 and
d783363f60 for similar issues.

The overload taking QDeadlineTimer::ForeverConstant was required,
prior to making it an enum class, because the conversion preferred
'int'. It was made an enum class for 6.6 and most overloads were
removed, including the one for QMutex, but QRecursiveMutex was
missed.
Pick-to: 6.6
