60c69b4da5 QLayout: add className() to a warning message
Since objectName() isn't always set, the className() makes it slightly
easier to find and fix the issue.

Also unify some wording "produce a warning", which is generic enough to
fit:
print warning in terminal
print warning in logviewer (if you're unlucky and have to use Windows?)
print warning in system journal (if you're unlucky have to use binary
systemd journal logs)

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.

d0eba2449a Create a promise wrapper for C++ and port existing uses
Currently, to use a promise from C++ we either have to use an ASM block
(which does not work well with dynamic linking) or declare exports in
the EMSCRIPTEN_BINDINGS block, which is cumbersome and cannot be chained.
This solution makes it easy to use js promises by introducing the
WebPromiseManager which dispatches callbacks to appropriate callers when
available.
This is a preliminary patch for FileSystem support, which will heavily
use async APIs.

122aa530d6 wasm: add qtwasmtestlib
qtwasmtestlib supports writing asynchronous tests for
the web platform.

Asynchronous test functions differ from normal test
functions in that they allow returning from the test
function before the test has completed:

void TestObject::testTimer()
{
    QTimer::singleShot(100, [](){
        completeTestFunction(); // Test pass if we get here
    });
}

Currently one logging backend is supported which
writes the results to an html element. See the README
file for further documentation.

f814cc6a79 rhi: metal: Switch back to presentDrawable
This convenience should be, according to the Apple docs, equivalent to
calling present from a scheduled handler. (which on its own makes it
unclear why we switched in the first place)

In practice it seems the two approaches are not identical. It looks
like that once a frame is submitted earlier than the next display link
callback, the throttling behavior we implement in beginFrame()
(waiting on the semaphore for the completion of the appropriate
command list etc.) starts exhibiting unexpected behavior, not
correctly throttling the thread to the refresh rate. Changing back to
presentDrawable does not exhibit this at all.

The suspicion is that presentDrawable is probably doing more than what
the docs suggest, and so is not fully equivalent to calling present
manually from a scheduled handler.

Therefore, switch to presentDrawable now, which restores the expected
cross-platform behavior, but make a note of the oddity, and also
prepare the hellominimalcrossgfxtriangle manual test to provide an
easy, self-contained application to allow experimenting in the future,
if needed.

This allows Qt Quick render thread animations to advance at the
expected speed (because the render thread is correctly throttled to
the refresh rate), even if the render thread decides to generate a new
frame right away, without waiting for the next display link update.

Without this patch, attempting to get updates not via requestUpdate(),
but by other means (timer etc.) leads to incorrect throttling, and so
the triangle in the test app is rotating faster than expected - but
only with Metal. Running with OpenGL on macOS or with any API on any
other platform the behavior will be correct. Even if scheduling
updates without display link is not efficient, and should be
discouraged, not doing so cannot break the core contract of vsync
throttling, i.e. the thread cannot run faster just because it renders
a frame not in response to an UpdateRequest.

Amends 98b60450f7 (effectively reverts
but keeps the code and the notes because we might want to clear this
up some day)

The siginfo_t parameter allows us to show what process sent a signal or

crashing signal was indeed sent due to a crash.

dda9c9e2bc moc: fix use of escape sequence of more than one character
We had the code to calculate the length, but were improperly using it
only for the offset, not the length of the string or its containing
array. That resulted in the generated moc output containing:

 QT_MOC_LITERAL(111, 5), // "\xffz"
 QT_MOC_LITERAL(114, 5), // "\0012"
 QT_MOC_LITERAL(117, 23), // "slotWithAReallyLongName"

The two strings are described as occupying 5 bytes (length 4 + null
terminator), which is incorrect. The offset was correct: 114 - 111 = 3
and 117 - 114 = 3. The new output is:

        QT_MOC_LITERAL(111, 2),  // "\xffz"
        QT_MOC_LITERAL(114, 2),  // "\0012"
        QT_MOC_LITERAL(117, 23),  // "slotWithAReallyLongName"

The effect of the array size calculation would only be felt if moc
decided it needed a second string array (for strings over 65535 bytes),
which would cause the offsets in the second array to be all wrong. There
was no such test until now.

Drive-by fixing of the newline, indentation, and the stale comment
referring to QByteArrayData (Qt 5).

2e12479e06 QGraphicsScene: respect that items can override selection changes
QGraphicsItems may override itemChange to prevent certain attribute
changes. Overriding ItemSelectedChange this way is explicitly documented
to be allowed.

However QGraphicsScene::clearSelection did not test whether items were
in fact deselected after the call to setSelection, and always cleared
the stored set of selected items.

Fix this by checking the actual selected state of the item as we iterate
over them, and store those items that are still selected in a set that
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
selectionChanged signal correctly (and does not if all selected items
block being deselected).

122270d6be Long live the ICU-based QStringConverter interface!
This adds support for additional codecs to QStringConverter when ICU is
available.

We store the converter in the state (d[0]), and its canonical name in
d[1]. We need the name there, as in the clear function we close the
UConverter, and set the pointer to null. Consequently, the actual
conversion functions might need to re-open the converter again. The
advantage of this approach is that clear is used in the destructor of
State, and with this approach we properly clean up the state.
There is however a disadvantage: The clear function was so far also used
for resetting the state when QStringConverter::resetState . Discarding
the whole Uconverter for that is however rather costly. For that reason
we modify resetState to call a new function, State::reset. For existing
converters, it behaves the same as clear; for the ICU based converter,
we call the more efficient ucnv_reset. Code compiled against Qt 6.4 can
benefit from this more efficient version; code compiled against older Qt
versions will continue to work, as the conversion functions can just
recretate the converter from the name.
We can distinguish between ICU and non-ICU converters by checking if the
UsesIcu flag is set.

QStringConverter::name is changed to return the name stored in d[1]. The
interface of the ICU converter has a dummy name, so code using the old
name function from QT < 6.4 still returns something, namely a message
asking the user to recompile.
The function is moved out of line, as we need to check for the private
ICU feature, and want to avoid having that check in the public header.

As the QStringConverter ctor taking a name now can allocate memory, it
can no longer be noexcept. Removing the noexceptness is safe, as it was
only added after Qt 6.3.

Note that we cannot extend the API consuming or returning Encoding, as
we use Encoding values to index into an array of converter interfaces in
inline API.

Further API to support getting an ICU converter for HTML will be added
in a future commit.

Currently, the code depending on ICU is enabled at compile time if ICU
is found. However, in the future it could be moved into a plugin to
avoid a hard dependency on ICU in Core.

[ChangeLog][Corelib][Text] QStringConverter and API using it now
supports more text codecs if Qt is compiled with ICU support.

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.

cfcbf38f76 Teach qmake about digit-grouping apostrophes in numeric literals
It was previously understanding them as character literal delimiters,
with unfortunate consequences if a numeric literal contained an odd
number of them. Recognize that an apostrophe with a digit on each side
of it isn't the opening quote of a character literal (unless the digit
before it is preceded by a u). Extend the findMocs test to trigger the
bug, prior to the fix; verified it passes with the fix.

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())
does not result in signals being emitted, because we do not detect the
index change.

This patch uses indexBeforeChange to detect such situation and emit all
necessary signals.

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.

4912903e37 Endian: Remove old special integer bitfields
The only way to use them was to put them in a union and then write all
the members of the union to set the various bit ranges. As only one
member of a union can be active at any time, the compiler is free to
optimize those writes away, though. This has started happening in the
wild now.

As we have a replacement, we can remove the old and broken code now.
