This is better than nothing at all. The wording is taken from Carlos's
commit message when he added this shortly before 3.12 (but skip Since).
Skip the bit from his commit message explaining what this replaced; we
don't need to say all the less good things our convenience API replaces.
as per efd3758f6a strcasecmp() is not a C
standard thing (not that we bothered including any header for it anyway)
and so this test failed to build on Windows with Microsoft Visual C.
This is the excellent explanation from Emmanuele at
https://gitlab.gnome.org/GNOME/gtk/merge_requests/402#note_361210:
"
Every time you instantiate a type, the instance_init() function is called for each
parent type T_p of your type T; to preserve invariants, the class pointer inside
the instance data is set to the parent type before each invocation, until you hit
your type T. This means that calling GET_CLASS() inside an instance_init() function
will give you a pointer to the class vtable for the parent type T_p while you're
iterating over parent types. What if you want to access the actual class vtable of
the type T, though? Well, you can because the actual signature of instance_init() is:
void (* GInstanceInitFunc) (GTypeInstance *instance, gpointer g_class);
i.e. all instance_init() functions get passed the instance they are initialising
and the class vtable of the real type you're instantiating.
This is how GtkToolButton works: it "peeks ahead" at instance initialisation time,
to use the button_type class field of the actual type you're instantiating,
and calls g_object_new() with it to store the resulting object in its own private
data structure.
This whole contrived mechanism is needed to allow out-of-tree tool buttons to just
set the button type on their class init, and have their parent class create the
button they want, instead of asking all tool buttons to do this themselves and have
a virtual function called get_button() for GtkToolButton to call whenever it needs
to operate on the button instance.
Now we're coming to a close: we cannot use the G_DEFINE_TYPE macro because the
instance_init() function it creates internally will not pass the class pointer
to your custom instance_init(). Since we cannot use G_DEFINE_TYPE, we also cannot use
G_ADD_PRIVATE either.
This is the reason why, when I ported GTK 3 to the new private instance data structure
macros, I left GtkToolButton alone. I should have left a comment there, because @matthiasc
tried doing that as well, and then had to revert it in commit 1c4a7bd5. So: my bad,
sorry about that.
If we want to drop the G_TYPE_INSTANCE_GET_PRIVATE and the g_type_class_add_private() calls,
we cannot use G_DEFINE_TYPE, but what we can do is unrolling what the macros do themselves:
- add a global GtkToolButton_private_offset variable
- add a static inline gtk_tool_button_get_instance_private() that does return
(G_STRUCT_MEMBER_P (self, GtkToolButton_private_offset));
- call g_type_add_instance_private (g_define_type_id, sizeof (GtkToolButtonPrivate)) inside
gtk_tool_button_get_type() and store the result in GtkToolButton_private_offset
- replace g_type_class_add_private() inside gtk_tool_button_class_init() with
g_type_class_adjust_private_offset (klass, &GtkToolButton_private_offset)
"
When we decide to fall back because the settings portal
is not present, adhere to that decision elsewhere. And
treat the fontconfig-timestamp like the other special-cased
settings, with G_TYPE_NONE.
Under Wayland, we are currently directly using GSettings
for desktop settings. But in a sandbox, we may not have
access to dconf, so this may fail. Use the new settings
portal instead.
As GSettings now supports session-specific defaults, GNOME Classic
no longer uses a separate schema and the decoration layout is always
determined by the regular schema.
This essentially reverts commit add67b516c (although the code was
moved since then).

By returning a default surface. The situation where there's no
currentContext arises when GtkCSS is trying to determine the
layout sizes so no actual display is necessary.

Do not lie to W32 about the formats that we provide or accept.
Originally the logic behind such lies was that GdkPixbuf allows us to
convert any supported image to BMP or PNG, and therefore we should
announce that we always provide/accept BMP and PNG along with other
formats.
But that's not how it works. GDK has built-in serializers and
deserializers for all pixbuf formats (where it just invokes GdkPixbuf
API) and will use them automatically to read or write GdkTexture
objects (internally wrapping GdkPixbuf objects where necessary). The
encoding and decoding of images is handled
by GdkContent(De)Serializers, backend has nothing to do with it.
Therefore W32 GDK backend should only offer formats that it can
actually do conversion for by itself (such as image/bmp <-> CF_DIB,
or text/uri-list <-> CFSTR_SHELLIDLIST).
and use 150 as natural-width.
Currently there's no way for a GtkEntry to be less
than 150px wide (apart from using "width-chars" property),
this is too much for a default minimum-width, an app
developer may need to have a shorter GtkEntry, for example
when the UI it's been shrunk by the user (see [1]) or when
you want to match the size of another widget (which is less
than 150px) see [2] for Evince bug on using
gtk_combo_box_new_with_model_and_entry() for PDF forms where
GtkEntry of ComboBox is too wide and doesn't match the combo
list width.
Using "width-chars" property may be a workaround to obtain
a short minimum-width for the entry, but is not a proper
solution for the mentioned cases as you may not know how
short your GtkEntry will be, or the fact that using "chars"
as a width unit is not pixel accurate.
Curious note: the commit that introduced the GtkEntry
minimum-width to be 150px is from 20 years ago, see

- Selection mode does not get the special devel styling.
- removed teh last-child() selector for it doesn't work anymore.
Better style all section of the headerbar than none. Proper fix pending.

Instead we just cache the monitor number and get
out of it the nsscreen when it is needed. This is
a requirement since it nsscreen it is not supposed
to be cached.

This was noticed in Firefox and demonstrated using a GtkBuilder ui file.
buildable_add_child() calls set_tab_label(), but the latter did nothing
to update the menu_label corresponding to that tab with the new text.
Using Builder to populate the tab child, only tabs other than last got
the right non-default labels, and even that was mostly coincidental, as
adding the main child called update_labels() via real_insert_page(), so
it took effect when the 2nd last main child is added, updating the rest
but leaving the last with the default label, not that given in Builder.
Fix by factoring out the code from child_reordered() to a new helper
menu_item_recreate() and calling that in set_tab_label(), so that
whenever the tab_label is updated, so is its corresponding menu_label.
This fixes the reported case and presumably others that we could write.

Comments matched to reassure the compiler that fallthrough is
intentional are supposed to precede the case or default keywords, at
least in GCC, so the one here did not suppress the warning with GCC. We
can just the if condition and put the comment at the end to solve that.
