a8c6958a87 Add QPlatformTheme::MenuBarFocusOnAltPressRelease
On Windows, pressing and releasing the Alt key moves focus to the
menubar. This is implemented in widgets, but not in Qt Quick.

Add a new theme hint so that we can make Qt behave natively on all
platforms, and make the common style's respective styleHint default to
the theme hint.

c3e2a624fb QApplication: send QHoverEvents with correct scenePosition()
The QHoverEvent ctor takes two points: pos and globalPos; pos is then
passed as both the scene and global pos to the QSinglePointEvent ctor,
which calls QMutableEventPoint::setScenePosition() on the persistent
QEventPoint instance and then detaches befeore setting ephemeral state.
Therefore, we must construct QHoverEvent with scene position first, not
local position, so that the right value is persisted; it's better to set
local position after the detach(), whereas it's too late to fix the
persistent point then.

e2fef733be Replace usages of Q_CLANG_QDOC with Q_QDOC
To allow the user to customize the C++ code that QDoc sees, so as to be
able to work-around some limitations on QDoc itself, QDoc defines two
symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an
entire execution of QDoc.

At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.

The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.

In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.

To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

2d381001da Add missing repaintManager check
This is likely a problem only after the 6.4 changes to move QQuickWidget
composition from OpenGL to QRhi.

Add an extra check to the condition when bailing out.

In QWidgetPrivate (qwidget.cpp) all similar calls into the
repaintManager are guarded by

  if (tlwExtra && tlwExtra->backingStore && tlwExtra->repaintManager)

therefore it makes sense to perform the same check in the other file too.

The assumption is that the check was not added here due to being outside
of qwidget.cpp.

fc76767692 Long live Q_UNREACHABLE_RETURN()!
This is a combination of Q_UNREACHABLE() with a return statement.

ATM, the return statement is unconditionally included. If we notice
that some compilers warn about return after __builtin_unreachable(),
then we can map Q_UNREACHABLE_RETURN(...) to Q_UNREACHABLE() without
having to touch all the code that uses explicit Q_UNREACHABLE() +
return.

The fact that Boost has BOOST_UNREACHABLE_RETURN() indicates that
there are compilers that complain about a lack of return after
Q_UNREACHABLE (we know that MSVC, ICC, and GHS are among them), as
well as compilers that complained about a return being present
(Coverity). Take this opportunity to properly adapt to Coverity, by
leaving out the return statement on this compiler.

Apply the macro around the code base, using a clang-tidy transformer
rule:

    const std::string unr = "unr", val = "val", ret = "ret";
    auto makeUnreachableReturn = cat("Q_UNREACHABLE_RETURN(",
                                    ifBound(val, cat(node(val)), cat("")),
                                    ")");
    auto ignoringSwitchCases = [](auto stmt) {
        return anyOf(stmt, switchCase(subStmt(stmt)));
    };

    makeRule(
       stmt(ignoringSwitchCases(stmt(isExpandedFromMacro("Q_UNREACHABLE")).bind(unr)),
            nextStmt(returnStmt(optionally(hasReturnValue(expr().bind(val)))).bind(ret))),
       {changeTo(node(unr), cat(makeUnreachableReturn,
                                ";")),  // TODO: why is the ; lost w/o this?
        changeTo(node(ret), cat(""))},
       cat("use ", makeUnreachableReturn))
    );

where nextStmt() is copied from some upstream clang-tidy check's
private implementation and subStmt() is a private matcher that gives
access to SwitchCase's SubStmt.

A.k.a. qt-use-unreachable-return.

There were some false positives, suppressed them with NOLINTNEXTLINE.

They're not really false positiives, it's just that Clang sees the
world in one way and if conditonal compilation (#if) differs for other
compilers, Clang doesn't know better. This is an artifact of matching
two consecutive statements.

I haven't figured out how to remove the empty line left by the
deletion of the return statement, if it, indeed, was on a separate
line, so post-processed the patch to remove all the lines matching
^\+ *$ from the diff:

  git commit -am meep
  git reset --hard HEAD^
  git diff HEAD..HEAD@{1} | sed '/^\+ *$/d' | recountdiff - | patch -p1

[ChangeLog][QtCore][QtAssert] Added Q_UNREACHABLE_RETURN() macro.

aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

df0b70eece StyleSheetStyle: Fix color of placeholder texts in text edits
Prior to 5.12, the placeholder text color was hardcoded to be the same
as the text color, but with an alpha of 128, i.e. semi-transparent. In
5.12, it instead got its own ColorRole in QPalette. So behavior
changed (In some cases in 5.12 and later, consistently from Qt 6):
placeholder texts no longer got a "light" (semi-transparent) version
of the css-styled color, but just the default gray/semi-transparent
black. That problem was reported as QTBUG-89815. However, the fix for
that bug did not apply the semi-transparency, but only used the same
color as the text. That caused a confusing visual expression, as
actual and placeholder text would look the same. This commit fixes
that.

The problem was made worse since there is no way to specify the
placeholder text color from css, i.e. to style it independently. A
follow up commit will aim to add that.

d46f317c8e Fix native titlebar offset and resizing upon unplugging dock widgets
When a dock widget received a native title bar upon unplugging, the
position of the newly unplugged dock widget was calculated without
taking the title bar's height into consideration.

Furthermore, dock widgets grew by the separator size upon undocking.
That is fixed by 10a143ccd7 by relying
on the assumption that passing a QRect() to the unplugging method
leads to un unchanged dock widget geometry.
However, when more than one dock widgets are docked in the same
main window dock on macOS or Windows, the size is stil increased.

This patch corrects the position offset for native title bars.
It also corrects an unplugged dock widget's geometry by the sparator's
size.

10a143ccd7 Prevent dock widget from resizing upon unplugging from main window
QDockWidgetLayoutState::itemRect() has been used to calculate a dock
widget's size when unplugging from the main window. This method is meant
to calculate the size of the rubber band, showing the dock widget's
dock area.

The rubber band is by QDockAreaLayout::sep wider (top or bottom dock)
or higher (left or right dock) than the respective dock widget. This is
to make sure the rubber band is never fully covered by the dock widget.

By wrongly using itemRect() also for the dock widget's size after
unplugging, the dock widget grows in size each time it is unplugged.

This patch passes an invalid QRect to QDockWidgetPrivate::unplug(), in
order to prevent resizing.

tst_QDockWidget::unplugAndResize() is extended to check size
consistency after unplugging (corrected for frame margins).

accc833e55 QComboBox: Prevent recursion in hidePopup
With styles that want the selected combobox item to flash, QComboBox
runs a modal event loop in hidePopup. This might result in reentrancy if
a mouseReleaseEvent is processed during the 60 ms of flashing.
Since mouseReleaseEvent calls hidePopup again, we end up reentrancy and
possibly undefined behavior which has caused crashes with Qt Creator on
macOS.

Prevent the reentrancy of hidePopup using a boolean flag. Since
QBoolBlocker (or QScopedValueRollback) cannot be used with a bit flag,
use a QScopeGuard to reset the flag reliably.

b646c7b76c add color picking support on wayland using the XDG desktop portal
On wayland applications are not trusted to perform screen grabs by
default, it is however possible to let the user specifically pick the
color of a pixel using the XDG desktop portal (otherwise used for
sandboxing etc.). Try to use this portal on unix systems by default.

To support this use case some extra abstraction is necessary as this
constitutes a platformservice rather than a platform feature. To that
end the QPlatformService has gained a capability system and a pure
virtual helper class to facilitate asynchronous color picking. When
supported the color picking capability takes precedence over the custom
picking code in QColorDialog.

52f4d0b0d2 QAbstractItemDelegate: tolerate that editor gets reparented
An item delegate might override destroyEditor to merely reparent the
existing editor out of the item view for later reuse, rather than
actually destroying the editor.

As of d0dffdfc01, the code calling
closeEditor() - which calls destroyEditor - might explicitly set focus
back to the item view parent of the editor. This needs to handle that
the parent of the editor might no longer be valid after the closeEditor
call returns, and rather store the old parent widget explicitly.

Add a test case that segfaults with nullptr access without the fix.

856bb38eaf Evaluate TranslucentBackground when (re)creating the window
The problem is reported in combination with the new 6.4 way of
handling texture-based widgets, but this looks like something that has
always been missing:

Setting WA_TranslucentBackground changes the QWidgetWindow's format,
and this is done upon calling setAttribute(). That's good for most
cases, but the changes to the QWindow's format are lost when the
window is destroyed and then the widget gets another window
later. This is not that common, but can happen.

For example, if a top-level widget is parented under something else,
and then later it is parented to null again, so that it is toplevel
once again, background transparency can be lost because nothing
re-evaluates the WA_TranslucentBackground flag after the initial
setAttribute(), and so the widget's second QWidgetWindow is not set up
accordingly (because this new QWindow may not have alpha specified in
the QSurfaceFormat which may or may not be a problem, depending on the
platform / windowing system)

The simple solution is to evaluate the attribute not just when setting
it, but also when a new QWidgetWindow is created for the widget.

e44edaac2c QWidget: use WA_InputMethodEnabled when ImEnabled is not implemented
In Qt 6.3, a check for WA_InputMethodEnabled was removed
in QWidget, to support IM queries also for read-only
widgets (7c6e4af48). This caused a regression on iOS, which
made the input panel open for widgets that didn't support
IM at all.

A patch was merged that solved the regression (3b12305575),
but it didn't take the widget attribute into account.
Since not doing so has the potential to cause regressions,
this patch will modify the affected code once more, so that
we instead fall back to test WA_InputMethodEnabled when
ImEnabled is not implemented. This will match closely
to the way ImEnabled was implemented in Qt 6.2.

Since we, with this change, now require that either ImEnabled
or WA_InputMethodEnabled is set, our own input widgets will
fail to support IM text selection when they're read-only, since
they actually don't implement ImEnabled.
This patch will therefore also make sure that we do so.

e1f25b1c8d Make it possible to check the accepted state of touch events in tests
QTouchEventSequence simulates a QPA touch event, potentially containing
multiple points. (Despite the name, it only calls qt_handleTouchEvent()
once, so it cannot really send a sequence of events; however, one event
can contain multiple touchpoints.) Delivery is synchronous, and we keep
return values through the QWindowSystemInterface::handleTouchEvent()
template functions; so the remaining step is to return a bool from
qt_handleTouchEvent(), so that we can return a bool from commit().
This allows tests to see the same perspective as a platform plugin can:
check whether the event was accepted or not, after delivery is complete.
Some tests in Qt Quick need to start doing that, to enforce correct
behavior in QQuickDeliveryAgent.

[ChangeLog][QtTestLib] QTouchEventSequence::commit() now returns a bool
so that tests can check whether the event was accepted during delivery.

dab0ef3670 Harden drag and drop handling in widget window
User code in an event handler can do arbitrary things, including
operations that lead to destroying the QWidgetWindow. An example is
what the autotest does: reparenting the top-level widget to under
another top-level upon the drop. Internally this leads to destroying
the drop target's QWidgetWindow as the widget is now a child, not a
top-level.

In fact some of the existing drag and drop handling code seems to be
prepared to handle the case of having the drag target widget destroyed
in the user's event handler during a drag-move. But none of it is
prepared for having the QWidgetWindow destroyed upon returning from
forwardEvent().

The associated bug report has the same root cause, it is just popping up
now via the new 6.4 behavior: adding a QOpenGLWidget to a widget
hierarchy upon a drop leads to getting a new QWidgetWindow (if the
window only had regular raster widgets before).

To solve this, avoid touching members on 'this' after the
forwardEvent(). It looks like the handlers for mouse events follow
this pattern already, no member data is touched after forwarding events
(not sure if that is intentional or just incidental but it is the safe
solution, even if this is not feasible everywhere, but ideally input
events should take this into account).

3b12305575 IM: Don't let all widgets support IM by default
A new property Qt::ImEnabled was added in Qt 5.3.
Since the already existing widgets with IM support
(3rd party included) didn't implement this property,
QWidget got the fall back logic that if a widget
was queried for Qt::ImEnabled, and the returned QVariant
was invalid (the widget didn't implement it), we
would, for backwards compatibility with Qt 4, return "true"
(meaning that the widget supports IM).

But a side effect from this fallback logic, is that now
any widget that doesn't implement ImEnabled (or input
methods at all) report that they support IM. This will
confuse platforms like iOS, which uses ImEnabled to decide
if the input panel should show, and if text selection tools
should be enabled. The result is therefore that if you click
on a QPushButton, the input panel will open.

This patch will implement a more careful strategy to check if
a widget implements IM, if ImEnabled is missing. Rather than
saying that all widgets that don't implement ImEnabled supports
IM, we now require that the widget also returns a valid QVariant
for Qt::ImSurroundingText. We assume then, that a widget that
doesn't do so will anyway not be in need of input method support
from the platform.

becomes the new selectedItems set (which will be empty if no item
overrides, which is the default).

Add a test that also checks that clearing the selection emits the

20a40035fa QTableView: set correct clip on QPainter when using spans
As it stood, QTableView would sometimes show drawing
artifacts when sections (rows or columns) where
rearranged, in combination with spans.

The reason is that the current code would go through the
currently visible cells in the viewport to check if any of
them where affected by a span. But the stored spans (in
QSpanCollection) is kept in sync with the column layout in
the model, and doesn't know anything about the rearranged
columns in the view. But a column with spans that is moved
to the left of the viewport can affect the painting of
the viewport as well, and needs to be taken into consideration.
For that reason, the current solution that uses
QSpanCollection::spanAt(x, y), will in that case fail.

Since it seems sensible that QSpanCollection is kept in sync with
the model (it makes model changes that affect spans easier to
handle), this patch will not change QSpanCollection. Instead, it
will iterate through all the spans (which is assumed to normally be
a limited size), convert them to the column layout of the view
(visual instead of logical), and find the ones that overlap.
Overlapping spans will, like before, be added as clip rects
to the QPainter.

e457aeec38 QBoxLayout: Add assertion that catches out of bounds insertion indices
As of Qt6, QList will assert that an insertion index is in range of
existing values. QBoxLayout interprets negative indices as "append at
the end". That part is covered.
Indices larger than the number of items in the layout would trigger the
assertion in QList, but after the insert method had returned. That would
make it hard to debug. This change asserts the index range before
inserting, thus making it easier to spot the problem.

fa814fcfea Provide overload for Qt::AlignmentFlags in item widget items
Amends 53ee4c8b1f, which deprecated
QListWidgetItem::setTextAlignment(int) etc and provided a typesafe
Qt::Alignment overload instead. However, Qt::AlignLeft by itself is of
type Qt::AlignmentFlag, it only becomes a Qt::Alignment when or'ed
with another alignment flag. So the deprecated int-overload was taken
by the compiler, resulting in a deprecation warning.

Add a Qt::AlignmentFlag overload in addition, and document it as
\internal since it is just a C++ technicality that we need both.

2ed54dedf3 QMainWindow: fix restoreState() for toolbars
Restoring the toolbar state of a QMainWindow could not update
QWidgetPrivate::widgetItem for the QToolBar, because at that point it
was still holding the pointer to the widgetItem of the previous state.
Later on, when the new state was successfully applied, the previous
state was deleted, and the corresponding widgetItem was reset to
nullptr.

This patch explicitly resets the QToolBar's widgetItem while updating
the state, so that it is later correctly updated while creating a
new QWidgetItemV2.

662184ac68 QComboBox: emit currentIndexChanged() and currentTextChanged() when the model is cleared
QComboBox uses QPersistentModelIndex to store the current index of the
underlying model. When the model is cleared, that index is automatically
invalidated, so calling QComboBoxPrivate::setCurrentIndex(QModelIndex())

79a11470f3 Accessibility: don't emit focus change when reason is window activation
If a window becomes active, then the accessibility system gets informed
about that already. Qt puts focus on the focus child of the activated
window afterwards, and if this emits another accessibility event, then
accessibility clients like Windows Narrator will stop reading the
activated window, and instead read about the focused widget.

This makes dialogs like message boxes poorly accessible.

Accessibility clients already know that a window became active, and can
query Qt about the focused child within that window.

Amend test case.

d38118c808 Make rhiFlush() support custom source DPR
The rhiFlush() implementation currently assumes that
QWindow->devicePixelRatio() is the correct scale factor for
transforming device independent window geometry to source geometry.

However, this assumption does not hold if/when we add support
for drawing to a rounded-up DPR, with a downscale later in
the rhiFlush implementation.

Fix this by adding a sourceDevicePixelRatio argument to rhiFlush(),
which is set to either QWindow::devicePixelRatio() or
QWidget::devicePixelRatio(), depending on from where it is used.

Change deviceRect() and friends in qbackingstoredefualtcompositor.cpp
to be scale*() functions instead which take a scale factor instead
of a QWindow. Update call sites to use srouceDevicePixelRatio
where that makes sense.

rect will work fine when there is no scaling, since the coordinates
will snap downwards. When a fractional scaling is applied however, the
main part of the line width will sometimes fall outside the clip rect,

painted.

of the line to the center of the intended pixel.

07d80deeab QtWidgets: restore Qt 5 compatibility for save/restore state
Several classes in QWidget use QDataStream internally in order
to save and restore state. These QDataStream usages were not
versioned, meaning that if Qt changes the serialization for some
datatype, then the data saved between different Qt versions becomes
incompatible. Note that the save/restore API in question just produce
opaque blobs as QByteArrays -- the user has no control over the
QDataStream objects and thus versions.

Fix by version the usages.

In QHeaderView this has caused a regression because QBitArray *did*
change version between Qt 5 and 6. In general, using QDataStream without
explicit versioning is a mistake, so deploy the same fix elsewhere as
well.

QTextEdit was abusing the width 0 to mean "no wrap, width comes from
contents", but since the value -1 means that already in QTextDocument,
QTextEdit now uses a width of -1 for that meaning.

53ee4c8b1f Item widgets: clean up treatment of Qt::TextAlignmentRole / CheckStateRole
The item widgets all have an API flaw: getters and setters for the text
alignment deal with int instead of Qt::Alignment.

Deprecate the existing setters and introduce others taking
Qt::Alignment. Store the alignment directly into the item widget (now
that views know how to handle it).

We can't change the getters without cluttering the API, so make that a
Qt 7 change. Users can prepare by forcibly casting the return value to
Qt::Alignment; this is going to work in Qt 6 and 7.

While at it: streamline the handling of Qt::CheckStateRole as well,
avoiding to rely on a pointless Qt::CheckState to int conversion
through QVariant (the setter stores a Qt::CheckState, but the getter
retrieves an int and converts it to a Qt::CheckState).

d9be9fedfb Add a clear action to QKeySequenceEdit
This can be really helpful for deleting shortcuts that one may never
intend to use so that they do not accidentally get in the way while
interacting with the user interface.

The workaround is to try to find the QLineEdit child of the
QKeySequenceEdit widget, but it is suboptimal. Some first-class citizen
API for this would be a more stable and cleaner solution as opposed to
poking implementation details as a user of the QKeySequenceEdit API.

The clear action would be configurable and opt-in as not everyone may
potentially want this to be turned on. Or at least, not by default
anyway. Also, not to suddenly change existing QKeySequenceEdit uses with
surprising UI changes after a Qt upgrade, this needs to be opt-in.

Moreover, some customers may have already used findChild<QLineEdit *>()
to add actions to QKeySequenceEdit in this way on the client side. So,
if it was enabled by default, they would suddenly get multiple actions
potentially for the same clear action. This would be certainly
undesirable.

The new clear property is based on the corresponding QLineEdit API for
consistency.

[ChangeLog][QtWidgets][QKeySequenceEdit] Added a clear action to
QKeySequenceEdit to be able to remove existing hotkey configurations.

741afd6752 QAbstractItemDelegate: fix rect given to tooltip handing
* The rect passed to QToolTip::showText() is in view coordinates,
not in global coordinates.

* Determining this rect in the first place doesn't need calling view->visualRect(index)
The view already did this before calling this method, and stored it in
option.rect, so just use that.

* The widget passed to QToolTip::showText() should be the viewport,
that's what option.rect is relative to (thanks Giuseppe!).

Found these issues when implementing my own tooltip handing (for a subrect

2b99a71b22 Stylesheet: Don't ignore item check indicator styling
Amends cf52d725156811754cd4e094b0984864795d1d58, after which most
indicator styling was no longer taken into account unless some other
item aspects were styled. Calling the baseStyle to draw the entire item
doesn't call back into the style sheet style for the indicator itself.

The QCommonStyle code that breaks the item up into individual sub
elements cannot be called for each element. E.g. turning off the check
indicator feature changes the layout of the item.

So if the indicator is styled, then we have to draw an otherwise empty
item with the style sheet style, and then clip the already painted rect
before calling the base style to draw text and highlighting with the
correct palette.

Add baseline test for QTreeView with different style sheets.

because the dock area becomes ambigous.

changes, and instead sometimes get stuck as e.g QPalette::Inactive
after application startup.

5d8a7652b9 QProxyStyle: reimplement event() handling
There is no use case for QProxyStyle to forward events to its base
style. QApplication does not send events to it; a style using e.g.
timers or so will have them active on *itself*, not on the proxy.

Moreover, forwarding *all* events is broken: QTBUG-96213 has been
triggered by forwarding DeferredDelete events sent to the proxy (thus
accidentally deleting the base style). But one can concoct many other
similarly broken situations; for instance, setting a proxy onto a base
style will make the style a child of the proxy.  That sends a
QChildEvent to the proxy (ChildAdded), and that event is then passed on
the base style, resulting in the base style receiving an event saying
"you have yourself as a child".

QStyle (which is QObject's descendent). So for the style to be deleted

means QObject::event, since neither QCommonStyle nor QStyle override

same area with the background color. However, under fractional DPR
scaling, the scaled version of the dirty rect may end up covering only

enabled, such pixels will be only partially filled with the background
color, leaving the clear color partially visible as glitches. This can
be seen in the dragdroprobot example.

Fix by disabling AA during background filling, as it has no purpose
then anyway.

71b3d18ea7 Notify about focus object changes upon widget destruction
If the active QWidget gets destroyed, then QWidgetWindow::focusObject
will return nullptr. If then no other object takes focus, then we'd
never emit change signals, and QGuiApplication's _q_updateFocusObject
(which then informs the input context and emits signals) didn't get
called. This left the input context with a dangling focus object
pointer, which resulted in crashes.

If the QWidget clears its focus, but the corresponding window doesn't
know that it had focus, then fall back to the widget's focus widget
to see if we have a change in focus, so that signals get emitted.

Add a test case that shows that we didn't call _q_updateFocusObject
by counting emissions of the QGuiApplication::focusObjectChanged
signal, which we emit in this function. The signal is emitted more
than once both when showing a widget, and now also when destroying
a widget that has a focus child. The former is a previous issue,
the latter is an improvement to not emitting the signal at all.

6880b7c39b Itemviews: start fixing mixups of int/enum for Qt's item roles
A model is supposed to return a Qt::CheckState for a CheckStateRole,
and a Qt::Alignment for a Qt::TextAlignmentRole. This is what the
documentation says (and what makes sense), but unfortunately
Qt's default delegate expected a plain `int` instead.
This sometimes worked (via QVariant conversions, e.g. when using a plain
enum) and sometimes didn't (e.g. when using a flag type).

This is confusing for end-users (and type unsafe, killing the whole
point of using enums and flags in the first place).

Adding some automatic flags<->int conversions through QVariant is
frowned upon, so I don't want to go there. Instead, add some private
convenience functions that extract either the right type from a variant,
or try to extract an `int` and convert it to the expected type.

Use these from within itemviews code.

4ac00ca901 QTabBar: let styles draw tab text with foreground role
QTabBar::setTabTextColor's documentation and implementation suggests
that the set color will always be used unless invalid, and that the
foreground role is used otherwise. QTabBar then sets the foregroundRole
palette entry to the specified color before calling the style. The intent
is evidently that the tabTextColor is used no matter the foregroundRole
(which by default is the role that contrasts with the background role).

If the styles always paint the text with WindowText, then the tabTextColor
gets ignored if the foregroundRole is not WindowText (perhaps because
the backgroundRole is set to Base).

Fix this by respecting the widget's foregroundRole when painting the tab
label in the common style (which is the only style that implements
drawControl for CE_TabBarTabLabel). QMacStyle and QStyleSheetStyle
need to be adjusted to prepare the palette consistently with the logic
in QTabBar.

78073f8ab6 Restore C++20-deprecated mixed-enum bitwise operators
C++20 deprecated arithmetic on enum types. For enums used on QFlags<>,
these operators have always been user-defined, but when the two enums
are of different type, such as QFrame::Shape and QFrame::Shadow, the
deprecation warning pops up.

We have in the past fixed these in our headers by manual casts, but
that doesn't help our users when our API requires them to OR together
enums of different type.

Until we can rework these APIs to use a variadic QFlags type, we need
to fix it in an SC and BC way, which is what this patch sets out to
do.

The idea is simply to mark pairs of enums that are designed to be ORed
together and replace the deprecated built-in bitwise operators with
user-defined ones in C++20. To ensure SC and BC, we pass an explicit
result type and use that to check, in C++17 builds, that it matches
the decltype of the result of the built-in operator.

This patch is the first in a series of similar patches. It introduces
said markup macro and applies it to all enum pairs that create
warnings on (my) Linux GCC 11.3 and Clang 10.0.0 builds. It is
expected that more such markups are needed, for other modules, and for
symmetry.

Even with this patch, there is one mixed-enum warning left, in
qxcbwindow.cpp. This appears to be a genuine bug (cf. QTBUG-101306),
so this patch doesn't mark the enums involved in it as designed to be
used together.

This patch also unearthed that QT_TYPESAFE_FLAGS, possibly
unsurprisingly so, breaks several mixed bitwise flags-enum operations
(QTBUG-101344).

68a4c5da9a Compose render-to-texture widgets through QRhi
QPlatformTextureList holds a QRhiTexture instead of GLuint. A
QPlatformBackingStore now optionally can own a QRhi and a
QRhiSwapChain for the associated window.  Non-GL rendering must use
this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still
rely on resource sharing between contexts. A widget tells that it
wants QRhi and the desired configuration in a new virtual function in
QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is
evaluated (among a top-level's all children) upon create() before
creating the repaint manager and the QWidgetWindow.

In QOpenGLWidget what do request is obvious: it will request an
OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget)
will be more interesting: it needs to honor the standard Qt Quick
env.vars. and QQuickWindow APIs (or, in whatever way the user
configured the QRhiWidget), and so will set up the config struct
accordingly.

In addition, the rhiconfig and surface type is (re)evaluated when
(re)parenting a widget to a new tlw. If needed, this will now trigger
a destroy - create on the tlw. This should be be safe to do in
setParent. When multiple child widgets report an enabled rhiconfig,
the first one (the first child encountered) wins. So e.g. attempting
to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same
top-level window will fail one of the widgets (it likely won't
render).

RasterGLSurface is no longer used by widgets. Rather, the appropriate
surface type is chosen.

The rhi support in the backingstore is usable without widgets as well.
To make rhiFlush() functional, one needs to call setRhiConfig() after
creating the QBackingStore. (like QWidget does to top-level windows)

Most of the QT_NO_OPENGL ifdefs are eliminated all over the place.
Everything with QRhi is unconditional code at compile time, except the
actual initialization.

Having to plumb the widget tlw's shareContext (or, now, the QRhi)
through QWindowPrivate is no longer needed.  The old approach does not
scale: to implement composeAndFlush (now rhiFlush) we need more than
just a QRhi object, and this way we no longer pollute everything
starting from the widget level (QWidget's topextra -> QWidgetWindow ->
QWindowPrivate) just to send data around.

The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split
is all gone. Instead, there is a QBackingStoreDefaultCompositor in
QtGui which is what the default implementations of composeAndFlush and
toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs
should continue working mostly as-is, apart from adapting to the
texture list changes and getting the native OpenGL texture id out of
the QRhiTexture)

As QQuickWidget is way too complicated to just port as-is, an rhi
manual test (rhiwidget) is introduced as a first step, in ordewr to
exercise a simple, custom render-to-texture widget that does something
using a (not necessarily OpenGL-backed) QRhi and acts as fully
functional QWidget (modeled after QOpenGLWidget). This can also form
the foundation of a potential future QRhiWidget.

It is also possible to force the QRhi-based flushing always,
regardless of the presence of render-to-texture widgets. To exercise
this, set the env.var. QT_WIDGETS_RHI=1. This picks a
platform-specific default, and can be overridden with
QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be
extended to query the platform plugin as well to check if the platform
plugin prefers to always do flushes with a 3D API.

QOpenGLWidget should work like before from the user's perspective, while
internally it has to do some things differently to play nice and prevent
regressions with the new rendering architecture. To exercise this
better, the qopenglwidget example gets a new tab-based view (that could
perhaps replace the example's main window later on?). The openglwidget
manual test is made compatible with Qt 6, and gets a counterpart in form
of the dockedopenglwidget manual test, which is a modified version of
the cube example that features dock widgets. This is relevant in
particular because render-to-texture widgets within a QDockWidget has
its own specific quirks, with logic taking this into account, hence
testing is essential.

For existing applications there are two important consequences with
this patch in place:

- Once the rhi-based composition is enabled, it stays active for the
lifetime of the top-level window.

- Dynamically creating and parenting the first render-to-texture
widget to an already created tlw will destroy and recreate the tlw
(and the underlying window). The visible effects of this depend on the
platform.  (e.g. the window may disappear and reappear on some,
whereas with other windowing systems it is not noticeable at all -
this is not really different from similar situtions with reparenting
or when moving windows between screens, so should be acceptable in
practice)

- On iOS raster windows are flushed with Metal (and rhi) from now on
(previously this was through OpenGL by making flush() call
composeAndFlush().

dfe5f99120 Fix QDockWidget's dock area permissions after hovering
When a QDockWidget's dock areas are restricted by setAllowedAreas(...)
and a second QDockWidget is hovered over it, the first QDockWidget can
be docked to any dock area of the main window. Area restrictions will
be ignored.
That is due to the first QDockWidget being implicitely mutated into a
QDockWidgetGroupWindow upon hovering. By definition, the latter has no
docking restricitons.
This fix adds a check if a QDockWidgetGroupWindow has a single QDockWidget child.
In that case, the single child's area permissions will restrict docking.

b20cf7feee QLabel::setPixmap(): remove the no-op self-masking
When calling QLabel::setPixmap() with a 1bpp pixmap (i.e. a bitmap), and
that pixmap didn't have a mask set, QLabel would then set the pixmap as
its own mask.

This seems to be a no-op due to how QPixmap::setMask is coded:

  void QPixmap::setMask(const QBitmap &mask) {

    // ...

    if (static_cast<const QPixmap &>(mask).data == data) // trying to selfmask
      return;

  }

Moreover, in order to convert the pixmap to a QBitmap, the code would just
straight downcast it, triggering UB (if the input to setPixmap wasn't a
QBitmap to begin with).

I *guess* this was done this way to avoid a QBitmap::fromPixmap call,
which however is not expensive at all if the pixmap is already 1bpp,
which QLabel::setPixmap checks explicitly (before attempting to mask the
pixmap). I don't know the historical reasons for the code to have the
shape it had (and the code history is from before open governance).

So get two birds with one stone: remove the no-op and also the UB.

a74cdf778c Implement QFormLayout::set/isRowVisible
Hiding a row in a form layout is inconvenient to do as access to the
widgets in each row is cumbersome. In addition, a row might include a
layout for the label or the field column, and we can't hide layouts and
instead need to navigate to the widgets inside the layout. And even if
an application developer does all that, the spacing calculation doesn't
ignore hidden rows.

Add setRowVisible and isRowVisible APIs with the usual overloads.
Implement the logic to traverse a layout item to its contained widgets,
so that they are explicitly hidden when a row is hidden, and skip hidden
rows in the spacing calculation.

Note that as long as the completer popup is a toplevel widget not parented

453f469216 QAbstractItemView: do not access invalid model indices (3/N)
The slots connected to rowsAboutToBeRemoved and columnsAboutToBeRemoved
attempt to find a new current index by scanning the model around the
existing current index -- in case that index is indeed about to be
removed.

The problem is that the scanning was done without any sorts of bounds
checking; instead it was relying on the model's index() to return an
invalid index for an out of bounds request.

Fix that by adding bounds checking. Since models are not supposed
to return invalid indices for in-bounds index() calls, added some
warnings if that happens.

For some reason, the code handling rows and columns isn't perfectly
symmetrical. Rows are searched both forwards and backwards, while
columns only backwards, and the related code is slightly different.
Filed QTBUG-100273 to try and understand what's going on.

0d9f4e7526 Make one QT_REMOVED_SINCE/QT_BUILD_REMOVED_API per module
A single global QT_REMOVED_SINCE will start hurting us once more
modules downstream of QtCore start using the mechanism.

With every use of feature, the set of code that needs to compile under
QT_BUILD_REMOVED_API increases. Since we use QT_REMOVED_SINCE in
situations where overloading the new and the old function don't work
in general, this means all code included by any removed_api.cpp needs
to be very carefully written to ensure that any calls to the overload
set formed by the combination of old and new function(s) don't create
ambiguities.

Likewise, the set of APIs that change semantics under
QT_BUILD_REMOVED_API also increases. At some point, the combination of
removed_api.cpp including almost every module header and almost every
header exposing source-incompatibilities when included in
removed_api.cpp will make maintenance a headache.

By making QT_REMOVED_SINCE and QT_BUILD_REMOVED_API per-module
(QT_CORE_REMOVED_SINCE, ...), easy now that we generate the export
macros using CMake, we limit the scope of this problem to the module
using the feature. Downstream modules (say, QtWidgets) will now see
the QtCore API like every other user, even in the
widgets/compat/removed_api.cpp TU.

cb27ed30f7 QCSS: Support Qt 5-style integer property selectors
In Qt 5 style sheets, objects could be selected by an enum-type property
using the integer value of the enum value, e.g

QToolButton[popupMode="1"] { ... }

In Qt 6, the the new meta type system and QVariant implementation enabled
QVariant::toString to return the string representation of the enum value
instead for a property containing an enum. Since QStyleSheetStyle's
attribute matching is string based, this breaks the Qt 5 style selector,
and QCSS code instead needs to use e.g.

QToolButton[popupMode=MenuButtonPopup] { ... }

While the new syntax is arguably preferable, this is an unintentional
change that silently breaks style sheet code (no error or warning at
compile- or run-time).

To support Qt 5-style selectors, we have to change the StyleSelector
interface of the QCssParser API so that we can pass through what type
of value the attribute extractor should return; if an integer string "1"
is provided, then we need to compare the enum integer value; if the
string provided does not represent a number, then we need to compare the
name of the enum value.

Since the pure virtual attribute() method that needs to be implemented
to extract the attribute value of the node is implemented in modules
outside qtbase, add a second virtual method that takes the entire
QCss::AttributeSelector, which includes the value to match. Extractor
implementations can use it to evaluate which type of data to return for
an exact match. The default implementation calls the old attribute()
method so that existing StyleSelector implementations continue to work.

Make the respective change in the QStyleSheetStyleSelector, and simplify
the surrounding code. Adjust other StyleSelector implemnentations in
qtbase. As a drive-by, remove the superfluous virtual declaration from
those overrides.

Once submodules are adjusted to override this virtual function instead
of the (now no longer pure) virtual attribute() method, that method can
be removed.
