It allows to disconnect a signal handler from GObject instance and at the same
time to nullify the signal handler.
Provided also a macro for handler type conversion.
Some of these have a negative master/slave connotation, and they add no
value. Change or drop them.

Those lists were getting very long. We can’t quite entirely automate the
list generation since Meson doesn’t have a range() function, but we can
at least combine three of them into one.

So long, and thanks for everything. We’re a Meson-only shop now.
glib-2-58 will remain the last stable GLib release series which is
buildable using autotools.
We continue to install autoconf macros for autotools-using projects
which depend on GLib; they are stable API.

They should either be generated at build time, or ignored completely,
depending on the presence of --[enable|disable]-man.

The tool was ported to Python, but we should not mention the programming
language used, in case we port it to some other language in the distant
future.
Weak-pointers are currently lacking g_set_object() & g_clear_object()
helpers equivalent. New functions (and macros, both are provided) are
convenient in many case, especially for the property's notify-on-set
pattern:
if (g_set_weak_pointer (...))
g_object_notify (...)
Inspired by Christian Hergert's original implementation for
gnome-builder.

The example code defines an interface with three methods. The preceding text
reads 'This interface defines two methods'. This appears to be because the
example code was changed without updating the surrounding text.

We should show how to properly use glib-mkenums with Autotools, in
the hope that fewer people will be caught cargo-culting rules written
in the late '90s.

By default, only build man pages and gtk-doc if the build-deps were
found. To force-enable, pass -Dwith-docs=yes and -Dwith-man=yes.
Also use a foreach loop for man pages instead of listing them all
manually
We're in the process or rewriting other tools in Python to reduce the
number of dependencies of GLib.
Additionally, making glib-genmarshal a Python script reduces the
complexity when cross-compiling, as we don't need a native build to
generate the marshallers.

It's unnecessary, and only adds visual noise; we have been fairly
inconsistent in the past, but the semi-colon-less version clearly
dominates in the code base.

Currently the doc is incomplete when builddir!=srcdir
(e.g. debian package) because glibconfig.h is generared from
configure.ac and is thus missing from srcdir. This leads to
missing doc for symbols like G_GINT64_FORMAT.

Change it to a running example of a file viewer application with a file
class and various derived classes and related interfaces. Hopefully the
reader can relate to this a little better than to their maman.

Remove some outdated references to an old example, and add a row in the

• Remove copies of function declarations from the explanation — if
people want those, they can follow links to the reference manual.
• Add markup to make C code more defined.
• Remove use of first person and irrelevant name dropping.

So that first-time users don’t fall into the trap of reading about the
gory memory layout details of GType and GObject when all they wanted to
do was derive a class.

Use G_DECLARE_INTERFACE and G_DEFINE_INTERFACE. Fix a couple of typos.
Add some comments to empty functions to make it obvious they’re

Restructure the section of the how-to which covers the header and source
code boilerplate for declaring and defining GObjects to use the new
G_DECLARE_*_TYPE macros. Present both final and derivable types.
Trim various supporting paragraphs.
Rename ‘class functions’ to ‘virtual functions’ to use consistent,
modern terminology.

Make it a little easier to find the GType conventions page, which I
guess should be the canonical guide to how to name things.
This adds a brief mention of the valid characters in a type name to the
conventions page.

Add G_DECLARE_DERIVABLE_TYPE() and G_DECLARE_FINAL_TYPE() to allow
skipping almost all of the typical GObject boilerplate code.
These macros make some assumptions about GObject best practice that mean
that they may not be usable with older classes that have to preserve
API/ABI compatibility with a time before these practices existed.

Along the same lines as g_clear_object(), g_set_object() is a
convenience function to update a GObject pointer, handling reference
counting transparently and correctly.
Specifically, it handles the case where a pointer is set to its current
value. If handled naïvely, that could result in the object instance
being finalised. In the following code, that happens when
(my_obj == new_value) and the object has a single reference:
g_clear_object (&my_obj);
my_obj = g_object_ref (new_value);
It also simplifies boilerplate code such as set_property()
implementations, which are otherwise long and boring.
Test cases included.

Used for the commonly used case (in signal emission) where we
initialize and set a GValue for an instance
Includes a fast-path for GObject
Overall makes it 6 times faster than the previous combination
of g_value_init + g_value_set_instance
Makes signal emission around 10% faster

On initialisation, GObject guarantees to zero-fill
class/object/interface structures. Document this so people don’t spend
forever writing:
my_object->priv->some_member = NULL;
my_object->priv->some_other_member = NULL;
