Viktor Arvidsson d9397479e6 QAbstractItemView: Release tab focus when hidden
When hiding a widget that has focus we try to focus the next widget in
the focus chain by running focusNextPrevChild. The abstract item view
overrides this to step the items but does not account for this hide case
which makes focusing not only not work, but also by hiding the widget
the selection in the item view gets changed.

Since the Android emulator on CI is running without hardware accelerated
graphics, showing the widget can take almost the same time as the timeout
for exiting the app with the "wrong" exit code 1. If running on Android,
increase the timeout to 1000 ms to avoid flaky failures. Un-blacklist
tst_QApplication::abortQuitOnShow() since the random failures are
taken care of by this patch.

Tor Arne Vestbø 6fbbbef260 QRhiWidget: Tear down resources before window has changed
We were handling QEvent::WindowChangeInternal, but based on what the
code is doing, what the comments say, and what QQuickWidget does,
the right event should be WindowAboutToChangeInternal.

This fixes a crash when reparenting a QRhiWidget into another widget,
where we could call removeCleanupCallback() on an RHI that was already
gone.

The fact that we have a stale RHI pointer at WindowChangeInternal time
is still problematic, and caused by our call to addCleanupCallback not
happening as it should for the first call to ensureRhi(), but this will
be fixed in a follow up.

Tor Arne Vestbø ea0cf4a9a2 tst_QWidgetRepaintManager::staticContents: Trigger resize via QWindow
QWidgetPrivate::setGeometry_sys wrongly triggers full update, which is
why the test was QEXPECT_FAIL, even on Windows, which does implement
static contents.

We can test the behavior without involving the broken QWidget behavior
by resizing the QWindow instead, which triggers a resize of the platform
window and will be fed back through QWSI, similar to when the user
resizes the window via the window frame.

The QEXPECT_FAIL message for the QWidget resize has been updated to
reflect why it's expected to fail.

tst_QWidget::optimizedResize_topLevel() has similar issues to this
test, and solves it by using Window specific platform code. For now
this test has been left alone, as there are a lot more going on in
that test in terms of workarounds and blacklistings, so it needs
further investigations.

Tor Arne Vestbø 1308f7e0b1 QWidgetWindow: Don't meddle with WA_WState_{Hidden/ExplicitShowHide}
In ccd3bf0871 we introduced code that would
ensure that our call to QWidgetPrivate::setVisible() from QWidgetWindow
would not result in WA_WState_Hidden being set. This code was later
modified in 51300566ff to apply to
widgets that were explicitly shown/hidden.

Unfortunately, the reset of the Hidden and ExplicitShowHide attributes
would in some cases result in the widget having only ExplicitShowHide
after being hidden, which is an invalid state.

It also resulted in the widget having both Visible, Hidden, and
ExplicitShowHide, if first being hidden via QWidget, and then
shown via QWindow, which in turn prevented the widget from being
hidden via QWidget::hide().

As we no longer rely on the adjustments to Hidden/ExplicitShowHide
to fix QTBUG-73021, we can remove the entire logic. Any setVisible
call to QWidgetWindow will either come from outside, in which case
we should respect that and set Visible/Hidden via QWidgetPrivate,
or the setVisible call is a result of QWidget itself (or its parent)
showing the QWidgetWindow, in which case the QWidget visible state
is already up to date and we skip the QWidgetPrivate::setVisible
call.

Tor Arne Vestbø 371d7ea19a Ensure QWidget::destroy() events and attributes match hiding the widget
When destroying a widget via QWidget::destroy(), we clear WA_WState_Created,
and then delete the QWidgetWindow, which in turn hides the widget. But
QWidgetPrivate::setVisible(false) skips hide_helper() if the widget has
not been created, which leaves out important events such as the hide
event, and even more important, fails to clear WA_WState_Visible. As
a result, the widget is left visible (and mapped), even if it has been
destroyed.

This is normally not a big issue for the main use of destroy(), namely
destructing the widget, but for cases where destroy() and create() is
used to recreate the widget this is important.

We now unconditionally call hide_helper() if the widget is not already
hidden. As a result, the widget will correctly be visible=false after a
destroy(). This in turn means we need to re-apply the visible state after
recreating the widget when we detect a mismatch in RHI configuration.

Due to our meddling of the Hidden and ExplicitShowHide attributes in
QWidgetWindow private, a QWidet::show() will not have any effect after
being destroy(). This is okey for now, as destroy() is internal to
a widget, and we make sure to either update WA_WState_Visible and
WA_WState_Hidden (in QWidgetPrivate::setParent_sys), or use the
QWidgetPrivate::setVisible() code path directly, which doesn't
have that issue. The root problem will be fixed in a follow up.

Tor Arne Vestbø 5ba0982b28 Don't set ExplicitShowHide on children when showing parent widget
As a result of using QWidget::setVisible to show the child widgets we
would end up also setting ExplicitShowHide. This is not in line with
the intent of ExplicitShowHide, which is to flag a widget as explicitly
shown/hidden by the developer, which in turn prevents Qt Widgets from
toggling WState_Hidden when the widget is reparented.

By using QWidgetPrivate::setVisible instead, we can show the child
without setting ExplicitShowHide.

As side effect of this is that we no longer reset WA_WState_Hidden
from QWidgetWindowPrivate::setVisible(). This is an issue when the
setVisible call comes as a result of destroying the QWidgetWindow,
as that is an implicit hide, and should not result in the widget
having WA_WState_Hidden. QWidget handles this case in hideChildren
by not calling QWidgetPrivate::setVisible -- instead doing its own
reset of WA_WState_Visible. We don't want to untangle this just yet,
so as a workaround we detect that the widget is already !isVisible(),
thanks to hideChildren having hidden it, and then skip the call
to QWidgetPrivate::setVisible that results from QWindow::destroy().

Tor Arne Vestbø 12203e94f5 QWidget: Clean up state that depends on QWindow from ~QWidgetWindow()
We were assuming that QWidget was in full control of QWidgetWindow
destruction, via deleteTLSysExtra(), and that we could limit any
cleanups to that function.

But in some situations QWidgetWindow is destructed from other code paths,
in which case we were left with dangling pointers to the QWidgetWindow
in both QTLWExtra, as well as the backingstore.

This can happen if there's a child widget hierarchy where there is not
a 1:1 mapping between QWidgets and QWindows, for example if the window
attribute WA_DontCreateNativeAncestors has been set. In this situation
our normal recursion into children in QWidget::destroy() stops at the
first widget without a window handle. When we then delete the top level
QWindow, the QWindow destructor will delete any child QWindows, which
includes our leaf QWidgetWindow.

We should probably fix up QWidget::destroy to continue looking for
children, even if we don't destroy the current child. But independently
of that we should make sure the QWidgetWindow cleans up when it's being
deleted, regardless of how it ended up there.

There's further room to clean up the deleteTLSysExtra() function and
friends, but that's been left for a later time.

Christian Ehrlicher ce8c81555d tst_qmdisubwindow: re-enable setFont() test
This test was disabled during Qt5 porting because it was unstable.
According to the discussion in the bug report, a deprecated function was
used to wait for the window to get exposed. This was later replaced by a
more robust QTest::qWaitForWindowExposed() but the test was not
re-enabled again.

Axel Spoerl 729e23f15f QPlainTextEdit: update viewport, when placeholder text disappears
QPlainTextEditPrivate::updatePlaceholderVisibility() issued a full
viewport update, when the document became empty and the placeholder text
needed to be shown. No update was issued, when the placeholder text was
replaced by a first text character entered.
That relied on the assumption, that the placeholder text would disappear
with the first text line being rendered (even if it has just one char).

When the placeholder text covered multiple line, only the first of them
disappeared.

This patch adds a boolean to remember, that the placeholder text is
shown. If that is the case and the first char is entered, a full update
is issued, to remove all lines of the placeholder text. The boolean flag
is cleared thereafter, to avoid unnecessary viewport updates.

isPlaceHolderTextVisible() is renamed into placeHolderTextToBeShown(),
because the method returns an instruction, rather than a state.

tst_QPlainTextEdit::placeholderVisibility() is adapted to test the
boolean flag, hence the real visibility of the placeholder text.
That extends its scope to the bug at hand.

Volker Hilsheimer 4f95e66f94 QWidget: deliver DragLeave events symmetrically
If a widget received a DragEnter event that it didn't accept, then the
UnderMouse widget attribute gets set. But the drag manager never got a
drag target, so the DragLeave event was never delivered, leaving the
UnderMouse attribute set incorrectly.

We always need to send DragLeave events to the receiver, even if the
DragEnter or DragMove was not accepted. Otherwise we are not in balance,
and the UnderMouse attribute will remain set.

This is a change of behavior and a very old bug, so only fixing this in
unreleased branches. Test case added to verify that explicitly generated
drag events result in the correct enter/leave events.

the widget the mouse is leaving, even if it didn't accept the DragEnter

Axel Spoerl d4f38a3632 QDialogButtonBox: Fix focus chain and default button assignment
QDialogButtonBox::layoutButtons() rebuilds the focus chain based on the
button layout. It relied on the fact that the last button in the layout
would point back to the first button. That is not the case, if
- a focus frame gets inserted in the chain, and
- the default button is not at the layout's first (=left) position.
In that case, the chain stops at the button left of the default button.
The default button can not be reached by tabbing forward. Back-tabbing
still worked.

By not "closing" the focus chain, the focus proxy was set to the first
button found in the layout. That is wrong, whenever the default button
is not at the first layout position. When the box got focus for the
first time, pressing "Enter" could lead to a non-default button being
triggered. A Yes/No message box would have No as its default button.
On Linux, it would pop up with "No" being highlighted, but "Yes" having
focus. Pressing Enter would trigger Yes, instead of No.

tst_QMessageBox::staticSourceCompat() heuristically defines the
button expected to be triggered by Enter. On Linux/KDE, it would pass,
when the wrong button was fired.

=> Always "close" the focus chain, by linking the last and first
buttons.
=> Make the default button the button box's focus proxy.
=> Change tst_QMessageBox::staticSourceCompat() to always expect No
being fired by Enter in a Yes/No box.

[ChangeLog][QtWidgets][QDialogButtonBox] Default button becomes
focus proxy of a QDialogButtonBox. This ensures that Enter triggers
the default button, instead of the first button in the layout.

Tor Arne Vestbø 5b09d9e6d6 Sync QWindow visible state during QWidget destruction
A call to QWidget::destroy() will end up in QWindow::destroy(), which
calls QWindow::setVisible(false).

A call to QWindow::setVisible(false) on a widget's window will under
normal circumstances end up in QWidgetPrivate::setVisible(), which in
turn recurses back into QWindowPrivate::setVisible(), via
QWidgetPrivate::hide_helper(), ensuring that the QWindow internal
state is updated, visibleChanged emitted, and show/hide events sent.

Durin QWidget::destroy() we end up in QWindow::destroy(), which calls
QWindow::setVisible(false), but in this case the widget no longer has
Qt::WA_WState_Created, so the hide_helper() call is skipped, and the
corresponding QWindow is not kept in the loop.

To work around this we could have checked for windowHandle() instead
of Qt::WA_WState_Created before calling hide_helper(), but that had
many other side effects, so we opt for a more targeted fix.

Tor Arne Vestbø 13074a967f Debounce QDeferredDeleteEvents in QObject::deleteLater()
We used to look through the event queue in QCoreApplication::postEvent,
and if we found an existing DeferredDelete event for the receiver we
would compress the two events into one.

This was changed in 99b89d30fa, as the
logic was causing O(n^2) for deleteLater, by using one of the bits
in QObjectData to track whether the object had already been deleted.

But it kept the logic for tracking this in QCoreApplication::postEvent,
and QCoreApplication::compressEvent would still do the work of deleting
the additional QDeferredDeleteEvents.

To avoid the unnecessary heap allocation of the QDeferredDeleteEvents
we can move the debouncing/compression to QObject::deleteLater().
We use the same mutex as in QCoreApplication::postEvent to guard
concurrent access to deleteLaterCalled.

A note has been added about the (preexisting) issue that the mutex
is not sufficient to prevent data races, as the deleteLaterCalled
flag is part of a bit-field, and we're not guarding any of our
other accesses to other bits.

As QDeferredDeleteEvents is private API, we can rely on no-one else
posting it than QObject::deleteLater(), which should be the case now
that tst_QApplication::sendPostedEvents() was fixed.

The documentation has been clarified as well. It's safe to call
deleteLater() more than once, but that's not _because_ other
pending events for the object are cleared. The latter behavior
is normal ~QObject() behavior. The documentation was probably
written at a point we didn't do any event compression at all
for QDeferredDeleteEvents.

Volker Hilsheimer 0441526448 QAIV: reset state if removing index while editing or committing
If the commit of data to a model index result in that index getting
filtered out, then the editor will be removed as part of committing the
data, and the index that the editor is associated with becomes invalid.
The subsequent call to closeEditor() will find that the index for the
editor is no longer valid.

This should not warn, and it should also not abort the clean-up process
early. Instead, identify that the editor that we want to closed is
already hidden. In that case, skip the warning and most of the cleanup
process, and proceed directly to the EndEditHint handling further down.

Add a test that simulates the two scenarios where this can happen:
either the committing of data results in the index being filtered out
by the existing filter; or the filter changes while editing, and the
index being edited gets removed. In both cases, we don't want to see a
warning, and the state of the item view should be reset correctly.

Axel Spoerl 7835f9e601 QSplashScreen: Enforce visibility by processing events
A splash screen is usually shown during initialization, before the main
window is shown. At that point, an application might not spin an event
loop. The documentation therefore recommends to run processEvents()
periodically, in order to ensure that the splash screen is actually
shown. Async window managers (e.g. XCB) might require more than one call
to processEvents() for the splash screen to be shown. It can't be
guaranteed, that a specific number of calls to processEvents() make the
splash screen visible. Calls to processEvents() are not considered
good practice in application code.

QSplashScreen::finish() uses a copy of QTest::qWaitForWindowExposed(),
to automatically close the splash screen, when the main window is
shown.

=> Re-write the static inline waitForWindowExposed to wait for the
widget's windowHandle()->isVisible(). That ensures visibility to the
window system.
The previous version waited for isExposed() to become true. That
ensured exposure to the application, but not visibility.

=> Intercept QEvent::Show and process events, until the splash screen
becomes visible.

=> Remove references to processEvents() as a requirement to show the
splash screen from the documentation. It remains a requirement for
processing mouse and keyboard events.

=> Re-activate tst_QSplashScreen and test visibility in the constructor
test function.

Drive by:
- implement switch in event override
- factor out paint event handling in a function
- update documentation about calling processEvents() to enable mouse
handling.
