It's deprecated from Meson 0.64. The replacement, fs.copyfile(),
is not useful here. It only copies from the source directory to
the build directory.

gtk_text_view_get_tabs() returns a copy (transfer full).

Fixes #123

Fixes #126

Required for Gtk::Widget's inheritance diagram.

GtkFileChooserNative is declared G_DECLARE_FINAL_TYPE.

* tools/m4/class_shared.m4: New file. It's a copy of the corresponding
file in glibmm. The copy in gtkmm makes it possible to
use _DO_NOT_DERIVE_GTYPE and _ABI_AS_WITH_DERIVED_GTYPE even if you build
against a version of glibmm where class_shared.m4 has not been updated.
* tools/extra_defs_gen/meson.build:
* tools/m4/filelist.am: Add class_shared.m4.

Meson: Re-structure warnings-related compiler flags for Visual Studio (gtkmm-3-24 branch)

See merge request !69

As Kjell suggested, don't use a for loop as get_supported_arguments() works on
a list and returns a list.

This warning only applies when compiling gendef.cc, when '/utf-8' is also being
used, so only apply that compiler flag there.  Move the '/utf-8' to be with the
other warning-related compiler flags for consistency's sake.

Also, only build gendef.exe if it is really needed, i.e., glibmm's gmmproc is
not able to produce headers that can export gtkmm's symbols via compiler
directives.

These warnings are not ones that we do need to be worried about when building
gtkmm, and we should extend applying them for the (generated) C sources as well

Don't (needlessly) repeat checking for the '/utf-8' compiler flag, and
use the `/wd4267` compiler flag only when building a 64-bit build, since
warning C4267 only applies for 64-bit builds.

Also, add a short description for the warning-related compiler flags for
Visual Studio.

g_object_run_dispose() unrefs a widget only if it has a parent.
Use g_object_unref() on all widgets without a parent.
Fixes #115

New versions of mm-common use the Python scripts doc_postprocess.py
and doc_install.py instead of the Perl scripts doc-postprocess.pl and
doc-install.pl when documentation is built.

The default value will be changed in future Meson releases.

Don't use deprecated python3.path() and execute(..., gui_app: ...).
Let import('python').find_installation() always find the python
installation used to run Meson.
Fixes #111

Avoid warnings from the clang++ compiler.

It's deprecated to implicitly declare a copy constructor, if there
is a user-deleted (=delete) copy assignment operator.

Make these builds distinct frmo the Visual Studio 2019 builds.

and set active items in the combo boxes, so something is shown.

Doxygen in a main project shall not be called before tag files have been
created or updated in subprojects.

* meson.build: If mm-common-get is not found in maintainer-mode
with 'required: false', try with 'required: true'.
Don't try to use tag_file, if documentation is not built.
* docs/reference/meson.build: Don't use variables from modules
that don't define doxytagfile. These are subprojects that don't build
their documentation.

Like the last NMake Makefiles commit, drop the ignores for warnings C4251,
C4273 and C4275 as the code is now free of items that trigger those warnings.

Drop the ignores for warnings C4251, C4273 and C4275 from the warnings that we
want to ignore, as the code is now free of items that trigger those warnings.

Also, reorganize the compiler flags for gtkmm-demo as it is actually the /GL
flag that triggered the internal compiler error when it is used with /EHsc on
32-bit Visual Studio 2015 and 2017 builds.  Likewise, disable the /LTCG linker
option when building Visual Studio 2015 and 2017 32-bit builds.

This class contains a std::vector<GType> member, so don't export this class as
a whole but export its methods individually.

This will eliminate warning C4251 and avoid having the built code depend on a
specific STL and compiler version

The decoration macro should be GTKMM_API, not GDKMM_API

Call add_dist_script() in a subproject, if meson.version() >= 0.58.0.
