1e4e006c3f QPainter: mark obsolete RenderHints as deprecated
RenderHint::HighQualityAntialiasing and NonCosmeticDefaultPen are
obsolete since Qt5 but not marked as such. Therefore add
Q_DECL_ENUMERATOR_DEPRECATED_X now so those two enumerations can be
removed with Qt6.

[ChangeLog][QtGui][QPainter] HighQualityAntialiasing and
NonCosmeticDefaultPen are marked as deprecated and don't have an effect
anymore

e5ab131c18 tst_QShortcut: Remove test widget and other member variables
Remove the mainW, edit widget member variables from the test and use
widgets instantiated on the stack in the tests.

For the data-driven tests, use a static QScopedPointer, which is
reset by a newly introduced TestEnd action.

The book-keeping logic maintaining a list of shortcuts can then be
removed.

The setupShortcut() helpers are simplified and the special case
TestWidget::SendKeyEvent is replaced by a lambda in
keypressConsumption().

555661b625 Update visible window's alpha when toggling WA_TranslucentBackground
QWidgetPrivate::updateIsTranslucent sets the surface format of the
window with the alpha based on the translucency attribute, so we need
to call this function when the attribute value changes. The test can
confirm that the window's requested surface format has changed, we
can't rely on what is actually set, and don't have to rely on
hard-coded values like 8bit alpha.

While WA_NoSystemBackground needs to be set for WA_TranslucentBackground
to have an effect, we can't clear the attribute when clearing
translucency (as it might have been set explicitly).

  * QDateTime::toTime_t() -> QDateTime::toSecsSinceEpoch().
  * QDateTime::fromTime_t() -> QDateTime::fromSecsSinceEpoch().
  * QDate::shortDayName() -> QLocale::system().dayName().
  * QTime by QElapsedTimer, where the deprecated methods of QTime
    were used.

- Modified the tests for the deprecated methods to be enabled only
  when the corresponding methods are enabled: when the deprecated
  APIs are disabled, the tests will be also disabled, and the
  compilation won't be broken.

0f3f143f6d Fix window shortcuts when a completer popup has focus
The completer popup has focus, making QShortcut direct to it's window
rather than to the window the completer belongs to. As QShortcut handles
the case for Tool windows that have a parent, but doens't do the same
for popups. And they shouldn't be treated the same way, as a context
menu popup for a e.g. text edit should in fact block the text edit's
shortcuts while open.

However, the completer popup is special, in that it explicitly makes the
widget completes for its focusProxy, which is what we can use to fix
this issue.

a7cbb8c639 QWidget: fix setTabOrder for compound widgets
81e298a51d fixed a case where the focus
chain was screwed up when the order was already correct. This worked
correctly in most cases but not when the next focus widget of the first
one had Qt::NoFocus.
The optimization check if lastFocusChildOfFirst is the same as second is
thrown away since it now does not longer screw up the focus chain and
the save would only be four pointer assignments.

b149f5d77a Overload QTextBrowser::setSource() to add optional type argument
Now that it's trying to guess whether the type is markdown based on
the file extension, there needs to be a way to override it. For example
it might be arranged that directory listings will be generated in
markdown format instead of HTML; then when loading a source URL that
is a directory, the application may override the type. The type for
the single-argument setSource(url) is UnknownResource to preserve
the existing behavior, but the user can override the guessing by
setting a specific type.

6492541df3 Support copy-pasting foreground images within same document
When using a texture for foreground color in text and copy-pasting
the text inside the same QTextEdit, the formatting would disappear.

Fixing this in a general way would require implementing some
other carrier format in the mime data than HTML, such as e.g ODF,
but it can quite easily be fixed for the case where the data
is pasted in the same document, or even different documents
as long as they have a reference to the image in the formats.

[ChangeLog][QtWidgets][QTextEdit] Added support for copy-pasting
foreground brushes with textures within same document.

21dcb96ddc QStyleSheetStyle::repolish: only run on direct children
When re-parenting, some widgets change their children. For example
QLabel, when set to rich text, will not update, until receiving a polish
call, at which time getting a list of all children recursively and then
trying to call functions on them will crash, since the children change
in the middle of this operation.

06d753e87b Brush up and stabilize tst_QSizeGrip
- Remove unused dummyWidget and thus empty slots initTestCase(),
  cleanupTestCase().
- Add slot cleanup() checking for an empty top level widgets list
  and introduce QScopedPointer to ensure it passes.
- Use QTRY_VERIFY in hideAndShowOnWindowStateChange().

Flakyness has been observed on openSUSE:

 FAIL!  : tst_QSizeGrip::hideAndShowOnWindowStateChange(Qt::Window) '!sizeGrip->isVisible()' returned FALSE. ()
           Loc: [tst_qsizegrip.cpp(126)]
