Creating a continuation with QtFuture::Launch::Async policy does not
work well with the example, because it still needs to update the UI
once the async continuation is finished. If the user decides to
close the application while the async continuation is executed,
the next continuation will be accessing data from the destroyed
Images object.
Fix it by using QtConcurrent::run() to do the "heavy" work in a
separate thread, and use a QFutureWatcher to handle the results of
the async execution. Update the example documentation accordingly.
After this patch the example still shows the usage of continuations
and onCanceled()/onFailed() handlers. However, it now does not
illustrate the usage of different launch policies and continuation
contexts. It might not be a big issue, because the QFuture
documentation describes these topics rather extensively.

Old examples inherited from Qt 4 tend to set some state, such as
enabling the depth test or culling, in initializeGL(). Newer examples
tend not to do this; they rather set the necessary state in paintGL().
This mattered little (or not at all) in the past, but with WebAssembly
and WebGL there are limitations in the GL context management in the
wasm platform plugin. Under certain conditions, esp. when
QOffscreenSurface is involved, it looks like the same native context
gets reused, which means there is a chance of unexpected changes to
the current state between calls to initializeGL() and paintGL(). (and
also between paintGL() calls) See QWasmOpenGLContext for details.
Update the textures example the same way we did for the cube one.
Add a note to the QOpenGLWidget docs about this problem.

A comment said how to do this, so I gave it a try. Added a note to the
instructions to save the next person to look at this from, as I
initially did, thinking the comment in the generated code had the URL
wrong.
It turns out that some of the newer additions to the IANA registry
have semantics elements that spread across several lines. I don't know
the XSLT magic to replace each newline in a value, along with its
preceding and following spacs, by a single space, so adapted the XSLT
to produce C++ raw strings to wrap these multi-line entries. That'll
produce somewhat ugly output, so left a TODO for the better solution.

The tooltip example moves shape items within a QWidget. Shape items are
stored in a QList of objects. When an item is moved, its pointer is
taken from the QList and stored in a member variable. To have the moved
item on the bottom of the list, QList::move() is called. This
operation re-arranges the list objects, and the member variable starts
pointing at a wrong object.
This patch changes the list from a list of objects, to a list of
pointers. Shape items are therefore allocated on the heap.
A destructor is added to free the heap with qDeleteAll.
The example's documentation is adapted accordingly and a snippet for
the destructor is added.
As a drive-by, int is replaced by qsizetype where it was used as an
index of a QList.

3a449bbb69 amended the code to remove

not have a lock associated when waking a condition variable; what I
misunderstood was the scope of the lock, which (and this underlines
the importance of commenting _what exactly_ a lock protects, for
each and ever lock) protected both the buffer as well as the counter
of the buffer. This made my reasoning flawed: it is necessary to keep
the lock while notifying, otherwise the counterpart could verify the
condition isn't satisfied and wait (e.g. see numUsedBytes==0), missing
the wake from the other thread (which could arrive between the check and
the wait).

The lock and unlock of the Android deadlock mutex is now part
of the internal implementation instead of limited to the enum
based permission API. It is unclear why 8bca441b6f added
the guard only to this API and not to the string based API
as well.
The check for isBackgroundLocationApi29 has been removed,
as the logic seemingly resulted in accepting every single
permission type except location permissions if used via
the enum-based API.
Since Android's platform permission API doesn't have an
Undetermined status, we keep a hash of the status for each
permission type, and by default checkPermission() would
return Undetermined, until a requestPermission() call
is done which updates the internal hash, and after that
checkPermission() would return properly Granted/Denied.

When submitting applications to the iOS and macOS AppStore the
application goes through static analysis, which will trigger on
uses of various privacy protected APIs, unless the application
has a corresponding usage description for the permission in the
Info.plist file. This applies even if the application never
requests the given permission, but just links to a Qt library
that has the offending symbols or library dependencies.
To ensure that the application does not have to add usage
descriptions to their Info.plist for permissions they never
plan to use we split up the various permission implementations
into small static libraries that register with the Qt plugin
mechanism as permission backends. We can then inspect the
application's Info.plist at configure time and only add the
relevant static permission libraries.
Furthermore, since some permissions can be checked without any
usage description, we allow the implementation to be split up
into two separate translation units. By putting the request in
its own translation unit we can selectively include it during
linking by telling the linker to look for a special symbol.
This is useful for libraries such as Qt Multimedia who would
like to check the current permission status, but without
needing to request any permission of its own.

Many features of today's devices and operating systems can have
significant privacy, security, and performance implications if
misused. It's therefore increasingly common for platforms to
require explicit consent from the user before accessing these
features.
The Qt permission APIs allow the application to check or request
permission for such features in a cross platform manner.
The check is always synchronous, and can be used in both
library and application code, from any thread.
The request is asynchronous, and should be initiated from
application code on the main thread. The result of the request
can be delivered to lambdas, standalone functions, or
regular member functions such as slots, with an optional
context parameter to manage the lifetime of the request.
Individual permissions are distinct types, not enum values,
and can be added and extended at a later point.

The example was refactored to use the PMF connection syntax.
However this introduced a problem: when connecting a QAbstractButton
to a slot that has a default parameter, the semantics of the connection
change between string-based connections and PMF.
Specifically: when connecting the
QAbstractButton::clicked(bool checked = false)
signal to a slot like
View::zoomIn(int level = 1)
then a string-based connection like
connect(button, SIGNAL(clicked()), this, SLOT(zoomIn()))
would call zoomIn without carrying the signal's parameter over.
In other words, zoomIn's parameter is defaulted. The same connection
using PFM instead is
connect(button, &QAbstractButton::clicked,
this, &View::zoomIn)
which would "connect" the arguments. This makes emissions that pass
false as clicked's parameter result in a zoomIn by 0.
Fix it by avoiding the default parameter of zoomIn -- just split
the function in two (zoomIn and zoomInBy).

QPlatformTextureList holds a QRhiTexture instead of GLuint. A
QPlatformBackingStore now optionally can own a QRhi and a
QRhiSwapChain for the associated window. Non-GL rendering must use
this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still
rely on resource sharing between contexts. A widget tells that it
wants QRhi and the desired configuration in a new virtual function in
QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is
evaluated (among a top-level's all children) upon create() before
creating the repaint manager and the QWidgetWindow.
In QOpenGLWidget what do request is obvious: it will request an
OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget)
will be more interesting: it needs to honor the standard Qt Quick
env.vars. and QQuickWindow APIs (or, in whatever way the user
configured the QRhiWidget), and so will set up the config struct
accordingly.
In addition, the rhiconfig and surface type is (re)evaluated when
(re)parenting a widget to a new tlw. If needed, this will now trigger
a destroy - create on the tlw. This should be be safe to do in
setParent. When multiple child widgets report an enabled rhiconfig,
the first one (the first child encountered) wins. So e.g. attempting
to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same
top-level window will fail one of the widgets (it likely won't
render).
RasterGLSurface is no longer used by widgets. Rather, the appropriate
surface type is chosen.
The rhi support in the backingstore is usable without widgets as well.
To make rhiFlush() functional, one needs to call setRhiConfig() after
creating the QBackingStore. (like QWidget does to top-level windows)
Most of the QT_NO_OPENGL ifdefs are eliminated all over the place.
Everything with QRhi is unconditional code at compile time, except the
actual initialization.
Having to plumb the widget tlw's shareContext (or, now, the QRhi)
through QWindowPrivate is no longer needed. The old approach does not
scale: to implement composeAndFlush (now rhiFlush) we need more than
just a QRhi object, and this way we no longer pollute everything
starting from the widget level (QWidget's topextra -> QWidgetWindow ->
QWindowPrivate) just to send data around.
The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split
is all gone. Instead, there is a QBackingStoreDefaultCompositor in
QtGui which is what the default implementations of composeAndFlush and
toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs
should continue working mostly as-is, apart from adapting to the
texture list changes and getting the native OpenGL texture id out of
the QRhiTexture)
As QQuickWidget is way too complicated to just port as-is, an rhi
manual test (rhiwidget) is introduced as a first step, in ordewr to
exercise a simple, custom render-to-texture widget that does something
using a (not necessarily OpenGL-backed) QRhi and acts as fully
functional QWidget (modeled after QOpenGLWidget). This can also form
the foundation of a potential future QRhiWidget.
It is also possible to force the QRhi-based flushing always,
regardless of the presence of render-to-texture widgets. To exercise
this, set the env.var. QT_WIDGETS_RHI=1. This picks a
platform-specific default, and can be overridden with
QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be
extended to query the platform plugin as well to check if the platform
plugin prefers to always do flushes with a 3D API.
QOpenGLWidget should work like before from the user's perspective, while
internally it has to do some things differently to play nice and prevent
regressions with the new rendering architecture. To exercise this
better, the qopenglwidget example gets a new tab-based view (that could
perhaps replace the example's main window later on?). The openglwidget
manual test is made compatible with Qt 6, and gets a counterpart in form
of the dockedopenglwidget manual test, which is a modified version of
the cube example that features dock widgets. This is relevant in
particular because render-to-texture widgets within a QDockWidget has
its own specific quirks, with logic taking this into account, hence
testing is essential.
For existing applications there are two important consequences with
this patch in place:
- Once the rhi-based composition is enabled, it stays active for the
lifetime of the top-level window.
- Dynamically creating and parenting the first render-to-texture
widget to an already created tlw will destroy and recreate the tlw
(and the underlying window). The visible effects of this depend on the
platform. (e.g. the window may disappear and reappear on some,
whereas with other windowing systems it is not noticeable at all -
this is not really different from similar situtions with reparenting
or when moving windows between screens, so should be acceptable in
practice)
- On iOS raster windows are flushed with Metal (and rhi) from now on
(previously this was through OpenGL by making flush() call
composeAndFlush().

Previously we only created object library static plugin initializers
for Qt plugins only, not user-project plugins.
The reason was that if a user tried to install the plugin target via
an export set, CMake would error out saying that the _init library is
not part of the same export set.
Introduce an OUTPUT_TARGETS option that would allow projects to get
the name of the generated _init target, so they can install it if
needed.
This was already done for qt6_add_qml_module, so we just introduce the
same option for qt6_add_plugin.
Now user static plugins will have an _init target created, which will
be propagated to consumers whenever the consumers link against the
plugin itself.
We also need an internal option to disable this propagation, because
it's handled a bit differently for Qt plugins which can be linked
either via finalizers or via usage requirements.

As a result of the implementation change, cleanup example projects
to ensure that they build successfully (the important part is
specifying the CLASS_NAME).
Only plugandpaint works properly with both shared and static Qt
builds.
echoplugin works with a shared Qt build, but not a static one due to
some assumptions in the C++ code about shared plugins.
styleplugin doesn't seem to work properly neither with shared Qt
builds nor static Qt builds, at least on macOS. But it builds fine.
For some reason even if the plugin is found, the style is not applied.

Outside tests, all in-tree callers of QObject::findChildren() pass no
name to match, and in my experience that is also true for the vast
majority of out-of-tree users.
Avoid the temporary QString creation in the caller and the repeated
QString::isNull() checks in the implementation by overloading
findChildren() without a name argument and checking for name.isNull()
only once, forking off into separate helper functions.
Adjust in-tree callers that used an explicit `QString()` argument in
order to pass options, which goes to show that `name` should never
have been the first argument of findChilden() in the first place, even
though I appreciate the symmetry with findChild() (the use-cases of
which, however, are radically different).
Change a `findChildren().size() == 0` call found while scanning for
findChildren() calls to `!findChild()` as a drive-by.
Modernize loops in the various qt_qFindChild{,ren}_helper() overloads
to match how the new code looks.
[ChangeLog][QtCore][QObject] Added findChildren() overload taking no
name (thus optimizing this common case).

Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.
Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.
The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.
