f2ab85429d Document the RSS Listing example
Add an image and a QDoc file, remove the (in some cases misleading)
doc comments from the CPP sources, group the slots all together in the
source so as to document them together, group the two private methods
together. Dust the header lightly with comments to classify the class
members and enclose relevant parts in QDoc snippet markers.

3c78f1e96e rsslisting example: rename a slot to reflect what it does
Many slots can be connected to one signal so, unlike a virtual method
that must be named for the situation in which it is called, a slot can
(so should) be named for what it does, rather than naming it to match
the signal it's connected to.

8fa28b0cff Update Cached Table example meta-data
Drop "Example" from the example's title, add SQL instead, and add it
to the Input/Output category of examples. It's a documented example,
does something meaningful, and looks reasonable. Having one SQL example
categorised so that it's easy to see that Qt includes that functionality
seems like a good idea. The other examples are mostly small API
examples that are still good to have as fully-functional apps rather
than just snippets.

1dd8b5ceec rhi: Make it a QPA-style private but semi-public API
qrhi.h, qshader.h, qshaderdescription.h (and qshaderbaker.h from
shadertools; done separately) become "RHI APIs", following the concept
of QPA APIs.

Mirror completely what is done for QPA headers, but using the "rhi"
prefix for the headers. This involves updating syncqt to handle the
new category of headers. (a note on the regex: matching everything
starting with "qrhi" is not acceptable due to incorrectly matching
existing and future headers, hence specifying the four header names
explicitly)

There is going to be one difference to QPA: the documentation for
everything RHI is going to be public and part of the regular docs, not
hidden with \internal.

In addition to the header renaming and adding the comments and
documentation notes and warnings, there is one significant change
here: there is no longer a need to do API-specific includes, such as
qrhid3d11[_p].h, qrhivulkan[_p].h, etc. These are simply merged into a
single header that is then included from qrhi.h. This means that users
within Qt, and any future applications can just do #include
<rhi/qrhi.h> (or rhi/qshader.h if the QRhi stuff is not relevant), no
other headers are needed.

There are no changes to functionality in this patch. Only the
documentation is expanded, quite a lot, to eliminate all qdoc warnings
and make the generated API docs complete. An example, with a quite
extensive doc page is added as well.

d75e772e22 RSS listing example: prefer setDevice() over addData(readAll())
The network reply is a QIODevice, so the QXmlStreamReader can be set
to read from it directly, which it might potentially do incrementally,
rather than by reading all the data in one go.

In the process, change the set-up of the reply to first check that it
got a valid URL, then check it got a reply, before doing things with
that reply.

how to do. And modern applications shouldn't use a (binary) mask to

don't paint pixels that should be fully transparent and use anti-aliased
or semi-opaque painting for pixels that should be translucent.

637e1542cf rsslisting example: fix bug in construction of title string
The correct time to clear titleString and linkString is at the start
of the item element, to avoid not only the left-overs from a previous
item but also any stray titles and links that don't belong to any
item. The channel element, that contains the items, may also have
title and link elements. This, indeed, lead to the first entry in the
displayed table having a "Qt Blog" prefix on its blog-post's title.

Fortunately the link was already being set, usually to empty, due to
the lack of rss:about attributes on item elements.

179b61c85f Update cbordump image to a higher-resolution one
Incidentally using reversed video, too, as that's what came naturally
to the terminal I was using. File is smaller, but text in the new
image is considerably more readable and the image is bigger.

The examples guideline calls for an image giving some idea what the
example is about, with a 4:3 or 5:4 aspect ratio. An image shorter
than its width wasn't practical, and getting a useful amount of
information in a height less than 3/2 of the width would have required
widening into blank space purely to satisfy the aspect ratio.  The
prior image's ratio was about 12:7, the new one's is roughly 2:3.

The old image showed the start of cbordump -a output, which is rather
less illuminating than the default output of formatted data; it's also
rather verbose, so was cut off part way through. It does, however,
illustrate how the annotated form might be useful for debug
purposes. The image also had a lot of blank space to the right of the
text of interest, wasting roughly half of its width; it could easily
have been cropped to 1:1 without loss of information. As example
data-set, it used ../savegame/save.dat, but without any hint to how to
generate that.

I decided to include a hint to how to generate a CBOR data file to
dump, then show the standard output and only the beginnings of the
annotated output, as the latter (even on its own) would make the
aspect ratio considerably taller. In the context of the standard
display, the preamble of the annotated one gives a reasonable feel for
what's going on, without belabouring the point.

5a3ac484db savegame ex.: revamp the way we (de)serialize JSON
JSON, unlike, say, QDataStream, allows building up objects independent
of some central object, and combining them into a QJsonDocument
later. This suggests returning QJsonObjects from a toJson() const
method instead of having the caller supply a QJsonObject. Doing it
this way enables transparent move semantics to kick in, too.

For deserialization, use a fromJson() named constructor for value-like
classes (where identity doesn't matter, only equality). Keep using
read(), too, and add a note to explain when to use which form.

Also, avoid the triple lookup from

   if (json.contains("key") && json["key"].isSoughtType())
      mFoo = json["key"].toSoughtType();

by using C++17 if-with-initializer and showing the trick with
Undefined never being of isSoughtType():

   if (const QJsonValue v = json["key"]; v.isSoughtType())
      mFoo = v.toSoughtType();

Adjust the discussion to match the new code, up the copyright years
and rename some qdoc snippet markers from nondescript [0]/[1] to
[toJson]/[fromJson].

Use e.g. Qt6::Core instead of Qt::Core. This is better matching the
find_package(Qt6 ...) call, and also avoids issues that the versionless
targets have.

5ddb5d1fee Rework imagescaling example to avoid potential crashes
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.

AndroidManifest.xml template was updated in qtbase in:

uses its own AndroidManifest.xml file, it need to be updated separately.

* android:exported="true": because the manifest sets an intent-filter,
and it then has to explicitly to avoid the warning [1].
* android:allowBackup="true": this has to be explicitly set, we set it
to the default value here [2].
* android:fullBackupOnly="false": SDK 23+ use this to deteremine to
user auto backup or not, we set it to the default value here [3].

5ebb9a8bf3 Tune textures example to work with wasm and update docs
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.

bcab157f75 Update table of CBOR tag descriptions in cbordump example
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.

051ba40997 cube example: Switch to a power-of-two texture
Just to make sure it runs with strict WebGL 1 implementations.

This cannot generally be a solution, naturally, so requiring
WebGL 2 is more likely the way to go, but in the case of this
example it seems the only thing we need is to resize the image
file, so we might just as well do that.

The '\meta category' command was used for tagging examples with a
specific category, used in Qt Creators Welcome mode.

As we want to also generate lists of examples belonging to a category
elsewhere in the documentation, replace the command with a macro that
expands to the original \meta command and also adds the example to
a group using the \ingroup command. This way, the category names can
be used as arguments to the \generatelist or \annotatedlist commands.
