7f80c96432 Stabilize tst_QApplication::touchEventPropagation
CI metrics show that this test was flaky ~38 time in 3 days.
The problem is old: after we get a surface, a window manager can still
decide to re-position the window.
The fix is to simply send the touch event in a position where it is sure
to hit the window (usually the offset is the title bar height).

The blacklisting seems to not have worked, I could reproduce the failure
on a linux/xcb machine.

e5c0371d18 Fix propagation of locale from widget to its children
Fix the condition in QWidgetPrivate::resolveLocale() to decide whether
to propagate locale: make it match setLocale_helper()'s condition when
deciding whether to propagate to descendants.  This lead to a
QDateTimeEdit's calendar popup not getting told what locale to use
correctly, unless we setLocale() on it overtly, which then blocked
propagation of locale changes to it unless QDateTimeEdit manually
propagated the changes.

Fix the documentation of WA_WindowPropagation to mention locale as
also being propagated (which it was in several places, only neglecting
this one in resolveLocale).

[ChangeLog][QWidget][Qt::WA_WindowPropagation] Propagate locale
consistently, along with font and palette, within the widget
hierarchy.  Previously, locale was propagated on ancestral
setLocale(), but not on creation of the descendant.

75f5e2bef2 Deprecate QString::null
It's a Qt 3 compatibility vehicle, and as such inherits the now-alien
property to distinguish empty and null strings. Particularly worrisome
is the following asymmetry:

   QString("") == QString::null          // false
   QString("") == QString(QString::null) // true

Instead of fixing this behavior, recognize that people might use it as
a weird way to call isNull(), albeit one that once was idiomatic, and
simply deprecate everything that deals with QString::null.

[ChangeLog][QtCore][QString] QString::null is now deprecated. When
used to construct a QString, use QString() instead. When used to
compare to a QString, replace with QString::isNull().

d6330a19b2 Use QT_CONFIG(library) instead of QT_NO_LIBRARY
For the windows file system engine, we add an extra macro to use
library loading if configured to do so, but avoid it on WinRT, as
none of the symbols would be found.

We also QT_REQUIRE_CONFIG(library) in the library headers and
exclude the sources from the build if library loading is disabled.
This, in turn, makes it necessary to clean up some header inclusions.

1d9270ee42 Fix DPI of QWidget with parent on a different screen
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.

qCountTrailingZeroBits() function from QtAlgorithms, making the

dfc338613e Make QPlatformSurface events work with QWindowContainer
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.

b952bd3605 QSizePolicy: make (Policy,Policy) ctor constexpr
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.

Saves a surprising 2K in QtWidgets text size on GCC 4.9, AMD64 Linux
stripped release builds.

626a4d89c2 QFormLayout: take the correct row in takeRow()
I didn't even try to understand what the old code was trying to do;
once you're told by a user that the code is wrong, you see that it is.

Fixed by just using the row as passed to takeRow() instead of trying
to do some storage-index calculations. The m_matrix indexing operator
does it all for us.

Added a test that checks that the expected field widget gets
returned. Fixed expected test data that was wrong, and just checking
that the implementation behaves as implemented, instead of as
documented.

Amends change 8fbae648db.

8b9b27bced QSizePolicy: add a transposed() method
In some situations, this allows for nicer code. It's also possible to
make this constexpr in C++11, whereas the mutable transpose() would
require C++14-style constexpr.

The new function should also be faster, since it just swaps the member
variables.

Because of constexpr-function limitations, the way the return value is
constructed needs to depend on the level of the compiler's C++11 support.
This is not the only class that requires uniform init to provide a fully
constexpr interface (QUuid and QBasicAtomic come to mind), so this should
probably be generalized across Qt at some point.

Added tests.

[ChangeLog][QtWidgets][QSizePolicy] Added transposed() method.

080daae7cd Plug new leaks in tst_QFormLayout
The new takeRow() functions return a pair of pointers to
QLayoutItems and, as the name particle 'take' suggests,
releases ownership of these layout items. Which in turn
means that the caller of the function is supposed to deal
with them.

This was not done here.

To fix, write a RAII class that takes ownership of the
returned layout items, deleting them when it goes out of
scope or gets a new value assigned (only move special
member functions are implemented, making the class move
-only).

Deleting the QLayoutItems is not so easy, though:
QFormLayout has a special function for clearing the
QLayoutItems out, so it appears that just calling their
destructors is not going to fly (though I don't know off
the top of the head why that should be a problem).

Solve this, for now, by adding the layout items back into
a temporary QFormLayout for destruction.

686c44a69b Plug remaining leaks in tests/auto/widgets/kernel
The usual:

- delete return values of QLayout::takeAt(), replaceWidget()
- delete styles
- delete top-level widgets
- delete actions

Either by naked delete, QScopedPointer or allocation on the
stack instead of the heap.

This fixes the remaining errors in GCC 6.1 Linux ASan runs of
tests/auto/widgets/kernel.

dc737fa0d7 tst_QShortcut: Fix UB (invalid cast) in shortcutDestroyed()
The slot is invoked from QObject::destroyed(), which is emitted

Fix by replacing QVector::replaceAll() with the erase-remove idiom,
which does not require the cast, because it can perform mixed-type
lookups.

da2c73ad2b Plug memleaks in tst_QWidget
We need to delete the style returned from QStyleFactory::create()
ourselves, so put them into a QScopedPointer.

The alternative would have been to create this once, as a member
of tst_QWidget, but this is the minimal approach that ensures
behavior just as the old code, but without the leak.

5571d2bf62 tst_QApplication: Fix UBs (invalid cast) in focusMouseClick()
Found by UBSan:

  tst_qapplication.cpp:1754:48: runtime error: member access within address 0x7ffda11f2220 which does not point to an object of type 'SpontaneousEvent'
  0x7ffda11f2220: note: object is of type 'QMouseEvent'

The code attempted to model the layout of a QEvent with another class
that allows public access to the memory location that (hopefully)
corresponds to QEvent::spont, gaining access by casting a QEvent
object to that specifically-crafted class.

Fix by the using the existing QSpontaneKeyEvent::setSpontaneous()
call, which, despite its name, works for all QEvent subclasses, and
which has already been fixed to not invoke UB (in bc087db).

In setMinAndMaxSize(), QLayout::removeItem() doesn't actually delete
the removed item. We have to do that ourselves (RAII not necessary,
since the spacer is owned by the layout until we remove it).

In distributeMultiCell(), allocate the QStyle subclass on the stack so
the compiler cleans it up properly on all exit paths (was:
unconditional leak).

In sizeConstraints(), QLayout::takeAt(), as the name suggests, doesn't

Likewise, in replaceWidget(), QLayout::replaceWidget() also doesn't
delete the affected item, but returns it. That's spectacularly bad API
design, but the leak is easy to fix: just delete the return value.
