Those overloads have been documented as obsolete, but never been deprecated.
Add the deprecation macros to trigger warnings as of Qt 6.2.
The overloads taking a single StandardButton should not be deprecated until
Qt 7, as otherwise porting from old to new API will require an unnecessary
cast to StandardButtons for calls with only a single enum value.
The unit test explicitly tests the deprecated members, so disable warnings
there.

C++20 via P1120 is deprecating arithmetic operations between
unrelated enumeration types, and GCC 10 is already complaining.
Hence, these operations might become illegal in C++23 or C++26 at
the latest.
A case of this that affects Qt is in key combinations: a
QKeySequence can be constructed by summing / ORing modifiers and a
key, for instance:
Qt::CTRL + Qt::Key_A
Qt::SHIFT | Qt::CTRL | Qt::Key_G (recommended, see below)
The problem is that the modifiers and the key belong to different
enumerations (and there's 2 enumerations for the modifier, and one
for the key).
To solve this: add a dedicated class to represent a combination of
keys, and operators between those enumerations to build instances
of this class.
I would've simply defined operator|, but again docs and pre-existing
code use operator+ as well, so added both to at least tackle simple
cases (modifier + key).
Multiple modifiers create a problem: operator+ between them yields
int, not the corresponding flags type (because operator+ is not
overloaded for this use case):
Qt::CTRL + Qt::SHIFT + Qt::Key_A
\__________________/ /
int /
\______________/
int
Not only this loses track of the datatypes involved, but it would
also then "add" the key (with NO warnings, now its int + enum, so
it's not mixing enums!) and yielding int again.
I don't want to special-case this; the point of the class is
that int is the wrong datatype. Everything works just fine when
using operator| instead:
Qt::CTRL | Qt::SHIFT | Qt::Key_A
\__________________/ /
Qt::Modifiers /
\______________/
QKeyCombination
So I'm defining operator+ so that the simple cases still work,
but also deprecating it.
Port some code around Qt to the new class. In certain cases,
it's a huge win for clarity. In some others, I've just added
the necessary casts to make it still compile without warnings,
without attempting refactorings.
[ChangeLog][QtCore][QKeyCombination] New class to represent
a combination of a key and zero or more modifiers, to be used

[ChangeLog][Potentially Source-Incompatible Changes] A keyboard
modifier (such as Qt::CTRL, Qt::AltModifier, etc.) should be

operator|, not operator+. The result is now an object of type
QKeyCombination, that stores the key and the modifiers.

This allows us to remove some usage of the QWidget pointer

we don't have a painter.

Call QGuiApplication and QScreen APIs directly to get geometries, and
make use of QScreen::grabWindow grabbing the screen it's called on when
called with WId == 0.
This assumes that QGuiApplication::screen and QWidget::screen never
return nullptr, which is already assumed in other places.
In QSplashScreen, simplify the code to operate on the screen of the
QSplashScreen itself. Remove the case that handles a QDesktopWidget
parent - QSplashScreen doesn't have a constructor that takes a
QWidget* parent anymore.
In the QEffect implementation, we can rely on the widget pointer
not being nullptr (it's tested in the free functions client code
uses).
Includes a few drive-by changes to coding style and logic in
qtooltip.cpp, where the tip label placement now prefers the screen
of the widget the label is created for, and uses the position only
as a fallback.
What remains is the special handling of QDesktopWidget and the
Qt::Desktop type in QWidget and QApplication.

Remove QDestopWidget public header, simplify the implementation that
maintains a Qt::Desktop type QWidget for each QScreen, and turn
QWidget's initial target screen into a QScreen pointer.
QApplication::desktop() now takes an optional QScreen pointer, and
returns a QWidget pointer, so that applications and widgets can get
access to the root widget for a specific screen without having to
resort to private APIs.
QDesktopWidgetPrivate implementations to look up a screen for an index,
widget, or point are now all inline functions that thinly wrap
QGuiApplication::screens/screenAt calls. We should consider adding those
as convenience APIs to QScreen instead.
Note that QWidget::screen is assumed to return a valid pointer; there is
code that handles the case that it returns nullptr (but also code that
trusts that it never is nullptr), so this needs to be defined, verified
with tests, and asserted. We can then simplify the code further.
