As part of eacd58d4e7, a mechanism was
added to prevent posting redundant UpdateRequest events to the top
level widget, managed by QWidgetRepaintManager. The mechanism relied
on a boolean that was set when posting an update request event, and
reset when processing the event for the top level widget, as part
of QWidgetRepaintManager::sync().
However, for paint-on-screen widgets, we don't post an update request
to the top level, we post it to the paint-on-screen widget directly.
And when processing that event, we don't paint the widget though the
normal QWidgetRepaintManager machinery, but instead call the paint
event via QWidgetPrivate::paintOnScreen().
As a result, an update() on a paint-on-screen widget would result
in never receiving updates for non-paint-on-screen widgets, as
we assumed there was no reason to send further update requests.
We could fix this by clearing the updateRequestSent flag as part
of the paintOnScreen() code path, but that's incorrect as the flag
represents whether the top level QWidgetRepaintManager needs an
update request event or not, and would lead to missed updates
to normal widgets until the paint-on-screen widget finishes its
update.
Instead, we only set updateRequestSent if we're posting update
requests for non-paint-on-screen widgets, which in practice
means the top level widget.
The paint on screen logic in QWidgetRepaintManager::markDirty
still takes care of rate-limiting the update requests to the
paint-on-screen widget, by comparing the dirty area of the
widget.
There is definite room for improvement here, especially in the
direction of handling update requests via QWindow::requestUpdate
instead of manually posted events, but for now this will have to
do.

When a QWidget was reparented, we would take care to reparent its
backing QWidgetWindow as well, into the nearest QWindow of the
new QWidget parent.
However we would only do this for the reparented widget itself,
and not any of its child widgets. In the case where the widget
has native children with their own QWindows, the widget itself
may not (yet) be native, e.g. if it hasn't been shown yet, or
if the user has set Qt::WA_DontCreateNativeAncestors.
In these scenarios, we would be left with dangling QWindows,
still hanging off their original QWindow parents, which
would eventually lead to crashes.
We now reparent both the QWindow of the reparented widget (as
long as it's not about to be destroyed), and any QQWindow
children we can reach. For each child hierarchy we can stop
once we reach a QWindow, as the QWindow children of that
window will follow along once we reparent the QWindow.
QWindowContainer widgets don't usually have their own
windowHandle(), but still manage a QWindow inside their
parent widget hierarchy. These will not be reparented
during QWidgetPrivate::setParent_sys(), but instead
do their own reparenting later in QWidget::setParent
via QWindowContainer::parentWasChanged(). The only
exception to this is when the top level is about to
be destroyed, in which case we let the window container
know during QWidgetPrivate::setParent_sys().
Finally, although there should not be any leftover
QWindows in the reparented widget once we have done
the QWidgetWindow and QWindowContainer reparenting,
we still do a pass over any remaining QWindows and
reparent those too, since the original code included
this as a possibility.
We could make further improvements in this areas, such
as moving the QWindowContainer::parentWasChanged() call,
but the goal was to keep this change as minimal as possible
so we can back-port it.

Previously, querying Qt::ImEnabled only returned the value of
isEnabling(), which is incorrect for edit widgets with read-only
properties set, as Qt::ImEnabled indicates whether text can be *input*
through the input method, which results in the IM being able to insert
text into read-only edit widgets.
The fixed version uses both isEnabling() and isReadOnly() values to
determine whether input methods need to be enabled. For some platforms
(like iOS and Android) that rely on IM to select text, a check for
ImReadOnly has been added to their QPA plugins to enable handles on
read-only input boxes.
At the same time, the imEnabledNotImplemented function in the test file
tst_qwidget was modified, since ImEnabling should give a _false_ value

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

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.

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

We were assuming that QWidget was in full control of QWidgetWindow

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.

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.

The tool tip content size uses an incorrect content margin, when it's
constructed. This content margin has been reset to correct value when
tool tip is positioned using placeTip(). But after that, the content
size not been recalculated.
This patch triggers updatesSize() to calculate content size with
updated content margin values.

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.

grabWindow() currently returns a null QPixmap on Android due to even
raster windows being backed up by OpenGL/QRhi. The test case uses
grabWindow() internally to grab contents to a pixmap and comparing
whether the pixmap contents are as expected, leading now to failures
due to null QPixmap being returned.
