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.

The constructor from a raw pointer should be
1) constexpr,
2) explicit, and
3) *private*.
We can do 1) without too much trouble.
2) is a (easy to fix) SIC in case of implicit conversions accidentally
relied upon from somewhere.
3) cannot be "easily" fixed by user code (they have to refactor), and
also, it's a BIC on Windows which encodes class members' access in
symbols. Someone may have been exporting some QList subclass, in turn
exporting the iterator classes, and therefore that someone now has the
constructors' symbols with a given access.
So, don't do 2+3 _just yet_ for user code, but set a deadline: Qt 6.5 is
the last that will support this. On Qt 6.6, we switch. All of this on
non-Windows, againt to avoid an ABI break. One can opt-in at any time
via a suitable define.
Given we have this define, use it to guard the other way around as well:
conversions from an iterator to a raw pointer should never be explicit
(there's std::to_address for this).
[ChangeLog][QtCore][QList] Converting a QList's iterator from and to a
raw pointer is deprecated, and will get removed in Qt 6.6. User code can

QList<T>::(const_)iterator both feature an implicit operator T*.
This operator exists in order to keep compatibility with Qt 5 code,
where QVector<T>::iterator _was_ indeed a T*. However, iterators are
not proxy objects and should not convert to T* (at least, not
implictly). In fact we've already seen compilers complain about
ambiguous calls when e.g. moving an iterator through an arithmetic
operation (say, operator+).
For instance, if one does
it + number
and the numeric argument of that call is not precisely qsizetype
(but, say, int), then the call is ambiguous between
operator+(iterator, int promoted to qsizetype)
operator+(pointer (converted from iterator), int)
One can imagine similar failures in generic code. In short: let's
deprecate (not remove) the implicit conversion, and let people use
iterators for what they are.

On systems that asynchronously resize the window to maximized or full
screen state, the window will become visible in its normal geometry
before it gets the final size by the windowing system. This might cause
multiple resize events, to each of which the widget's layout responds
with a call to its setGeometry implementation.
The QMainWindowLayout is special in that it will shrink dock widgets if
there is not enough space for them, but it doesn't grow them back once
there is. With the initial resize event being for a smaller size than
what was restored, the state is not restored correctly, but remains in
the state that fit into the smallest size with which setGeometry got
called.
To fix this, we have to keep the restored state around until the window
either gets a size that is large enough for it to fit, or until we can
be reasonably certain that the windowing system is done resizing the
window while transitioning it to the maximized or full screen state.
Since across the various platforms and windowing systems there is no
reliable way to know when the window reaches its final size, we have
to use a timer that we (re)start for each call to setGeometry with a
size that's not large enough. Once the timer times out, we have to
give up; then the last layout state calculated is the final state.
To calculate the size of the layout, introduce a function to the
QDockAreaLayout that returns the size required for the current sizes
of the docks. Refactor sizeHint and minimumSize (which were identical)
into a helper template that takes member-function pointers to call the
respective method from the dock area layout's content items.
Add a test case for various permutations of the scenario. The timeout
of 150ms is based on running this test case repeatedly on various
desktop platforms and X11 window managers.

This is a workaround for a problem in TextEdit.
The symptom is that when the user places the cursor inside
of a word and hits backspace, the last letter of the word
is removed instead of the letter just before the cursor.
The reason is as follows.
When stopping composing, the current cursor position has to
be maintained. To that end, QAndroidInputContext sends an
event containing the text to be committed and the cursor position
to the editor. But the resulting cursor position is wrong.
This patch adapts QAndroidInputContext to send two events:
One to commit the text, the second to place the cursor.
A real fix would fix the editor to correctly
handle the event containing both the committed text and
the cursor position.
