If a floating QWidget has a parent on a different screen, its DPI was
still inherited from the parent instead of taken from the screen.
The only reason we did was in case there is a customDpi set.
(customDpi is a private thing that is only used in designer to change
the appearance of the previewed widget)
So instead of recursing into QWidget::metric for each ancestor, just
use a for loop to find if one parent has a customDpi. If no customDpi
is found, then return the DPI of the right screen.

Embeddeding a QWindow via QWidget::createWindowContainer() fails to
deliver the SurfaceAboutToBeDestroyed event. This breaks any OpenGL
or Vulkan based QWindow that releases resources upon this event, and
is particularly critical with Vulkan where the only way to do properly
ordered swapchain - surface cleanup is via this event.
In the non-embedded case close() eventually ends up in an explicit
destroy() in QWindow. In the embedded case destroy() only gets called
from ~QWindow. This then silently breaks since the subclass' reimplemented
event() virtual is not getting called anymore.
To remedy the problem, simply add an explicit destroy() to
QWindowContainer.

Unfortunately, that ctor also takes a ControlType argument (defaulted),
and calls the non-constexpr, non-inline function setControlType().
In order to make at least the two-arg version constexpr, I added
a use of the ternary operator to check for type == DefaultType,
making all calls of the ctor that use type == DefaultType
constexpr. For init'ing an aggregate type without ctor in the
ctor-init-list, I needed to require uniform initialization, too.
C++11-style constexpr cannot call void functions, so I needed
to extract the transformation part of setControlType() into a
new function that returns the result instead of storing it directly.

Solve this, for now, by adding the layout items back into

There's a conflict between QGtk3Menu and QDbusPlatformMenuBar. The
problem is that on Unity the type of the platform menu instance must
be different depending on whether the menu is in the global menubar or
a standalone context menu.
Since QMenu creates a platform menu instance at construction time, it
does not yet know whether it will be added into a menubar. QMenuBar
checks that the QMenu already has a platform menu instance, and passes
it to the platform menubar. As a result, a QGtk3Menu instance is passed
to QDbusPlatformMenuBar.
Currently, a standalone QMenu does not use the native platform menu
instance. Only menus that are added to a QMenuBar do. Therefore we
don't need to create the platform instance when QMenu is constructed,
but only after it is added to QMenuBar. The platform menu instance
creation is implemented in QMenuBarPrivate::getPlatformMenu(), and
QMenu::setPlatformMenu() calls syncPlatformMenu() to take care of
syncing the QMenu properties and actions to the new platform menu
instance.
The macOS-specific methods QMenu::toNSMenu() and QMenu::setAsDockMenu()
rely on the platform menu instance, and must therefore create it on
demand.
This is a hot fix for the release blocker, not a long term solution.
In the future, if standalone QMenus are made to use native platform
menu instances, the instance must be created lazily when the menu is
about to be made visible.

It might happen that, when pressing Alt+X to trigger a shortcut for an
action in a menubar, that the user releases Alt first, followed by X. When
that happens, QMenuBar gains focus as if the user just pressed and
released Alt (to focus the menu bar). That's counterintuitive, frustating
and not what native Windows seems to do.
Fix this by resetting the "altPressed" state whenever a shortcut gets
triggered with the Alt key pressed.
(In the above discussion, X stands for any key).

Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.
This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

Before commit f1e9076809, mousePressEvent
called the virtual method setSelection(const QRect&, SelectionFlags)
with the 1x1 rectangle which contains only the clicked QPoint, unless
the SelectionFlag "Current" was set because Shift was pressed during
the mouse press.
Since that commit, the behavior has been changed such that the
rectangle is the one that is spanned by the center of the clicked item
and the clicked pixel. In theory, the result should be the same (i.e.,
only the clicked item should be selected), but
* the code path in QListView::setSelection for 1x1 QRects is more
efficient, and
* using a larger QRect can cause problems with custom views, see the
comments in QTBUG-18009
This commit ensures that the 1x1 QRect is used again, unless the
SelectionFlag "Current" is used.

doing this, it set up its display data, which could leave it with a
different time (rather than a different representation of the given
time) than it was asked to use.

The default should be false, meaning the application will prefer to
use a native menubar if the platform supports it. The application
author can set it to true if he wants to always use a Qt-rendered
menubar instead; or, he can call QMenuBar::setNativeMenuBar().
Qt and its plugins should not override the author's wishes.
Instead, if the platform plugin cannot create a native menubar
for whatever reason, createPlatformMenuBar() will return null,
and QMenuBar will fall back to using a Qt menubar instead.
The application can check the result via QMenuBar::isNativeMenuBar().
QMdiArea when maximized inside a QMainWindow with an empty title
does not replace the main window's title if we are using native menus.
This behavior turned out to be the same on Unity as it is on macOS,
so the autotest needed adjustment to expect that behavior whenever
the menubar is native, not only on certain platforms.
tst_QMenuBar::allowActiveAndDisabled() tests a standalone QMenuBar.
In f92f78094 it was disabled on macOS, but on Ubuntu it passes as
long as we force it to be a non-native menubar, so it should pass
that way on macOS too. Removed unused variable RESET to fix warning.
