f5eda09a63 Modify the target Square in the puzzle
targetSquare judges which square the position falls in. The point
scaling calculation method should not be used. The return value of
QPoint operator/ will be rounded up. Modified to separate the x and
y of position to calculate.

9beae46b59 Fix treemodelcompleter example
All nodes in the view were at the top level due to a spurious trimmed()
call.

The condition in the indentation calculation was flipped, leading to a
segfault.  Also, the input data does not contain tabs.  Remove the
condition that checks for tabs altogether.

This amends commit 3fede6cb54.

fb656c036d Remove .qmake.conf from this repository
This file was necessary for the qmake build and the CI.  The qmake
build is history, and the CI does now read .cmake.conf (see
QTQAINFRA-4392).

In addition to being superfluous, the existence of .qmake.conf
triggers QTBUG-76140 when building Qt examples with qmake.  Removing
the file alleviates the symptoms of this bug.

"Interestingly", to make the qmake build of examples work in the CI, we
have to adjust the dbus examples to not use nmake inference rules.  The
absence of .qmake.conf results in a different order of inference rules
in the Makefile, and nmake/jom pick up generated source files from the
source dir.  These are incompatible with the correct generated source
files in the build dir.  See QTBUG-96513 for details.

10eedd175e Doc: Centralize RFC documentation-links in rfc.qdoc
In the effort of repairing broken links as per QTBUG-96127,
a series of RFC links referring to `tools.ietf.org/html/*` were modified
to point to the new address that the site redirected to.

To simplify executing a similar task and to diminish the duplication of
manually inserted urls, the already existing `rfc.qdoc` file, containing
`\externalpage` commands directing to RFC locations, was enhanced with
links to all RFCs that were mentioned in the current documentation, so
as to aggregate this common category of links.

All links pointing to a `ietf` domain inside QDoc documentation blocks
were then changed to use the newly provided external-references.

3c1125d9fe CMake: Create plugin initializers for static user plugins
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.

Amends 91c65dd80c

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.

2b50c8bec0 QObject: optimize the common case of findChildren(QString())
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).

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
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.

92185d417d Fix BASE argument of qt_add_resources
The BASE argument of qt_add_resources now denotes the root point of the
alias of the file.  Before, BASE was merely prepended to every file that
got passed to qt_add_resources.

Old behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "images/button.png")

Alias is "../shared/images/button.png", and pro2cmake generated
QT_RESOURCE_ALIAS assignments to fix this.

New behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "../shared/images/button.png")

The alias is "images/button.png".  No extra QT_RESOURCE_ALIAS assignment
is needed.

The new behavior is in effect for user projects and for Qt repositories
that define QT_USE_FIXED_QT_ADD_RESOURCE_BASE.  Qt repositories will be
ported one by one to this new behavior.  Then the old code path can be
removed.

d4242b8af3 Revise deprecation of countriesForLanguage()
It was originally marked \obsolete without any comment on what was to
be used to replace it, or deprecation markings in the declaration, so
it got missed at 6.0. More recently it's been deprecated in favor of a
territory-based name; but actually it was obsoleted by (iterating the
territory() of each return from) matchingLocales() in Qt 4.8.

So back out of adding territoriesForLanguage to replace it and,
instead, mark it as deprecated in the declaration, in favor of
matchingLocales(). Also rewrite the implementation to be exactly that
replacement. Rewrote the one example using it.

50a7eb8cf7 Add the "Territory" enumerated type for QLocale
The use of "Country" is misleading as some entries in the enumeration
are not countries (eg, HongKong), for all that most are. The Unicode
Consortium's Common Locale Data Repository (CLDR, from which QLocale's
data is taken) calls these territories, so introduce territory-based
names and prepare to deprecate the country-based ones in due course.

[ChangeLog][QtCore][QLocale] QLocale now has Territory as an alias for
its Country enumeration, and associated territory-based names to match
its country-named methods, to better match the usage in relevant
standards. The country-based names shall in due course be deprecated
in favor of the territory-based names.

0e69349f6f Brush up the mandelbrot example
The example refines the image by running a number of passes
with increasing number of iterations, which is not really
visible to the user. Set an informational text string on
the generated image which provides this information
along with the elapsed time.
The idea is to do the same to the corresponding
Qt for Python example to have some sort of speed comparison
for number crunching.

Add a command line option for the number of passes.

Make the window a bit larger to accommodate the
information.
