79f62380f0 QAbstractItemView: Fix IM input starting edit session
Item views can open an editor widget on the first key press, and need to
take special care not to break input methods. The initial key press
starts compositing by the system input method, which is then interrupted
by the focus transfer to the editor.

To solve this problem, the widget needs to keep focus while the initial
composition is ongoing, and only transfer focus to the editor once the
composition is either accepted or cancelled by the user. Add a state flag
that is set during this initial preedit phase.

During this initial composition, the item view will receive all input
method events, and needs to forward these to the open, but not yet focused
editor for the user to get the correct visual feedback during the preedit
phase. The item view also needs to report to input method queries on
behalf of the editor to make sure that the IM UI is correctly positioned
without covering the user input.

Implement a test that simulates the sequences through synthesized
QInputMethodEvents; we can't simulate the entire system input stack.

223066d431 Don't clear focus if setParent doesn't change the parent
QWidget::setParent might be called to change the window flags, without
changing the parent. For those cases, we don't have to clear the focus.

Decouple the newParent state from the wasCreated flag. In most places
where newParent was tested, wasCreated was either tested previously and
can't be false anyway, or the code executed is irrelevant for widgets
that are not yet created (there can't be a paint manager). In the
remaining case, test wasCreated explicitly to maintain existing logic.

Add test for the cases where the previous code broke the focus, both
for QWidget and QDialog.

a5e5943d8a macOS: send enter/leave when a window opens/closes
Since macOS doesn't give us any event when a modal window opens,
we need to do so ourselves explicitly so that the current mouse
window gets a leave event when e.g. a popup opens, and an enter
event when the popup closes again. The case for modal dialogs is
partially handled by QGuiApplication already.

Note: We cannot rely on the transientParent of the opening/closing
window, as it's nullptr for QMenu windows even if the QMenu has
a widget parent.

Add a test for enter/leave events when a secondary window opens,
covering both the dialog and the popup case. For the dialog case,
we sometimes get two Enter events when the dailog closes, which
we have to tolerate for now.
To make the test pass on b2qt platforms, fix the offscreen plugin
to explicitly send enter/leave events in the same way as Cocoa
now does.

0246bfd40a Close QDialog via QWidget::close()
By going via QWidget::close() we ensure that if there's a QWidgetWindow
backing the dialog (which is almost always the case), we will plumb down
to QWindow::close(), resulting in QEvent::Close events to the QWindow.

Since we don't want QDialog subclasses to receive a call to a closeEvent
override that they didn't receive before (and which they might interpret
as rejection or cancellation), install a temporary event filter that
eats the QCloseEvent resulting from the call to close().

bedc588698 Always reset close-status of QWidget when trying to close
Move the status setting and resetting back into handleClose so that we
don't end up with it being set if handleClose is never called in response
to a close attempt. This can happen when QWindow's platform window has
already been destroyed.

Since QWindow::close handles that case gracefully and returns true,
we can safely call it multiple times.

Add test coverage to verify that we get exactly those close event
calls that we want.

dad1e14941 Forward touchEvents to children inside QGraphicsProxyWidget
This reapplies the fix from 1ecf2212fa,
using QApplication::translateRawTouchEvent to dispatch the touch event
received by the QGraphicsProxyWidget to the relevant child widgets
under each touch point.

In addition, limit the implicit grabbing of each touch point before
sending the event to those cases where we have to: touch pads, and
if the target widget comes from a closest-widget matching. And don't
call the QTouchEvent override of QEvent::setAccepted() on QTouchEvent
instances in QGraphicsView classes, as this will override each event
point's acceptance state.

This way, we can identify which touch points have been accepted after
event delivery, any only implicitly grab those points that were.
Otherwise, touch points not accepted by a proxied widget hierarchy
will still be part of an accepted event, and be grabbed by the
viewport of the QGraphicsView. This would then lead to infinite
recursion when the QGraphicsProxyWidget passes the TouchUpdate event
on to each touch point's grabber.

Re-activate the test case, and extend it with more combinations.
Refactor touch-event recording to make it easier to test multi-touch
scenarios.

7ba75d088c QWidget: close the QWindow in QWidget::close
We want to close the window, end full screen mode on macOS, and free
platform resources. This is all done by QWindow::close. QWindow::close
closes the platform window, triggering a closeEvent to QWidgetWindow,
which then calls QWidgetPrivate::close_helper.

This way, closing a window via QWidget::close, QWindow::close, or
interactively by the user are all equivalent.

The QCloseEvent generated by the widget needs to be spontaneous for
window-system generated events (i.e. the user clicked the close button),
and non-spontaneous if the window closes because of a call to
QWindow::close. To keep track of whether the event originated in an
explicit call to QWindow::close, add a boolean to the QWindowPrivate.

Add a test case that verifies that the window resources is destroyed,
and that events are delivered as they should.

ca69e5aeef Fix QListView assert when the last row is moved in IconMode
After the last row is moved, 0 will be returned when obtaining
row and column data. At this time, QListView::doitemslayout will
not call d->doitemslayout, so the QBspTree data structure will
not be cleaned up, leaving a stale tree structure behind. This
will trigger an assert during paintEvent handling if QListView is
set to IconMode

In QListView::ListMode the test for a valid model index doesn't
use an assert.

Call QListViewPrivate::clear explicitly if the column count is 0
so that the QBspTree and other data structures are cleared.

model that returns a 0 column count for an index after the model
structure was changed through a move of rows.

This reverts commit 1ecf2212fa.

The fix is not correct after all. TouchBegin goes to the correct
widget with the fix, but following TouchUpdate and TouchEnd events
now go to the viewport, as QApplication::translateRawTouchEvent always
gives precedence to the widget that Qt recorded to be the touch
grabber, which is the viewport. This results in infinite recursion,
as the proxy widget trying to send the touch events to the embedded
widget (expecting that translateRawTouchEvent will split it up) ends
up sending the events back to the viewport.

Leave the added test case as QEXPECT_FAIL, reactivate the (never run,
hence unnoticed) test that the fix broke.

a49ba9265f Reactivate QGraphics(Proxy)Widget unit tests
They were de-facto disabled in the qmake build system, and didn't make
it into the cmake build system either. The dependency to the fusion
style is not a build-time dependency since the test uses the
QStyleFactory to create the style, and if that fails, tests can be
skipped at runtime.

As a consequence of not being executed in CI for a long time, many
tests failed. Also, many tests were commented out or skipped as
broken, ambivalent, or nonsensical. Remove that dead code. The
QGraphicsWidget::initialShow test doesn't test anything that initialShow2
doesn't test, but makes incorrect assumptions, so remove it and rename
initialShow2 to initialShow.

Failing tests frequently left QWidget objects undeleted, causing all
subsequent tests to fails as well. Fix that with std::unique_ptr.

using QEXPECT_FAIL. The forwardTouchEvent test fails due to a bug

06235d36ae QGraphicsProxyWidget: fix propagation of high-precision events
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.

4982c872ef Don't crash in high-precision wheel scrolls on a QGraphicsProxyWidget
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.

33f9591e37 Implement missing support for 'em' and 'ex' lengths in style sheet
The Qt style sheet reference claimed that Length properties can be
specified in 'em' or 'ex' units, but that was never implemented.

Add the missing implementation. Since the sizes depend on the size of
the font of the current element, we cannot convert the units in the CSS
parser, but have to do so in the QRenderRule constructor, where we can
make a decision about which font to use if the style sheet itself doesn't
specify a font. Fall back to the widget font if possible; otherwise it
will be the application default font.

The implementation translates em into QFontMetrics.height, identical to
what is already done in the QCssParser. This is in line with the CSS
specification, but contradicts our previous documentation which stated
that 'em' means "width of M". Fix the documentation.

Unlike an acceptable effect in QTableView + QTreeView

bef57b317f testlib: Deprecate QWARN() in favor of qWarning()
The QtTest best practices documentations recommends using output
mechanisms such as qDebug() and qWarning() for diagnostic messages,
and this is also what most of our own tests do.

The QWARN() macro and corresponding internal QTest::qWarn() function
was added when QtTest was first implemented, but was likely meant as
an internal implementation detail, like its cousin QTestLog::info(),
which does not have any corresponding macro.

This theory is backed by our own QtTest self-test (tst_silent)
describing the output from QWARN() as "an internal testlib warning".

The only difference between QWARN() and qWarning(), besides the much
richer feature set of the latter, is that qWarning() will not pass
on file and line number information in release mode, but QWARN() will.
This is an acceptable loss of functionality, considering that the user
can override this behavior by defining QT_MESSAGELOGCONTEXT.

[ChangeLog][QtTest] QWARN() has been deprecated in favor of qWarning()

a7da8e0dab QWidget: cope with QObject::connect()'s incomplete SFINAE-friendliness
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
tst_qwidget and tst_qmenu.

188d739400 Sync default action when checking tool button programmatically
QAbstractButton::setChecked is not virtual, so QToolButton cannot
override to synchronize the default action's checked state. This resulted
in button and default action not being in sync when the checked state
of the button was changed programmatically, while changing the checked
state on the action kept the button in sync.

Connect to the button's own toggled signal instead to keep the state of
the default action in sync. Make it a unique connection to allow multiple
calls to setDefaultAction, which are used by QToolButton to keep the
button updated if properties of the default action change.

Add a test that confirms that button and action are synchronized both
ways, and that we only get single signal emissions when changing either
programmatically.

a1a6e3d21b Support pt units for sizes, as documented
Declaration::lengthValue only supported 'px' sizes, but one can transform
any 'pt' value into 'px' by multiplying with 1.33.

Notes: this ignores display DPI, and instead follows the W3C definition
of 'pt' and 'px' as absolute lengths [1].

[1] https://www.w3.org/TR/css3-values/#absolute-lengths

1pt = 1/72th of 1 inch
1px = 1/96th of 1 inch

so the conversion is px = pt * (72/96).

Add unit test that verifies this using QPushButton's icon-sizes property,
also with changed font in preparation of adding support for 'em' and 'ex'
units in a follow up commit.

26bebd2037 QListView: don't scroll if selected items are removed
For SingleSelection, removing the selected item will select the nearest
item and, if autoScroll is enabled, ensures that the newly selected
item is visible in the viewport. This may result in scrolling.

For Multi- or ExtendedSelection, this should not happen, as having no
selection is perfectly fine in those modes.
However, QListView still tried to scroll to the current item in response
to the currentIndexChanged signal. Since the currentIndex is at this
point already hidden, the rectangle for it became invalid, and the
attempt to scroll resulted in a one-pixel up-movement of the viewport
(since the invalid rectangle has width == height == -1).

Fix this by not scrolling if the rect for the index is invalid. Note that
the index is still valid at this point, so we can't shortcut the call
stack earlier. Add test that exercises the different combinations of
ViewMode and SelectionMode, and demonstrates the one-pixel
movement without the fix.

09d1196281 QMenu/QToolBar: remove addAction() functions
They're now in QWidget itself. Remove them from the API, but not the
ABI.

The QToolBar case is straight-forward. QMenu is a bit more complicated:

Since QT_CONFIG(shortcut) builds changed the signature of an existing
function instead of adding/removing an overload, we have to deal with
two cases: In a QT_CONFIG(shortcut) build, these overloads that take a
trailing QKeySequence parameter have been deprecated and therefore
cannot be removed. In a !QT_CONFIG(shortcut) build, the same functions
are 1:1 copies of QWidget functions and can be removed (from the API).

[ChangeLog][QtWidgets][QMenu/QToolBar] The addAction() functions have
been moved down into QWidget.

d2e88b8094 Fix auto completion in QFileDialog on Windows
Amends c0b3c06a7d.

The QCompleter used by QFileDialog uses starts-with matching of
the path parts, for all parts of the path. It uses the EditRole of the
underlying model for the data to match.

The path parts used for a path on Windows are "C:", "Users", "etc...",
and then finally whatever input has been typed so far. If we try to
match that against a starts-with rule against "Local Disk (C:)", then it
will fail and the completer will never have anything to show.

So, for the EditRole, return just the volume drive letter as we did before
c0b3c06a7d, not the volume name. Neither
can be edited anyway. This happens to then match the native file dialog
behavior, which doesn't complete "L" to "Local Disk (C:)" if the Computer
contents (ie. volumes) are shown.

Augment the QCompleter test case to cover that scenario (it already has
everything set up for this particular combination, even though we are
actually testing QFileSystemModel returning the correct data).

This should reduce the amount of fall-out from DST complications.
Also document the assumptions of QDateTimeParser's two fromString()

Since only QDateTime-returning methods will show the difference, and
it's at least somewhat odd to be using those on QDateEdit or

[ChangeLog][QtCore][Behavior Change] QDateEdit and QTimeEdit now
operate in UTC, to avoid spurious complications arising from time-zone
transitions (e.g. DST) causing the implicit other half to combine with
the part being edited to make an invalid result. Returns from their
dateTime() and other methods returning QDateTime (max/min) shall thus
be in UTC where previously they were in local time. QDateTimeEdit
continues using local time. The default can be over-ridden by
setTimeSpec(), as ever.
