This is not strictly needed from an introspection perspective, but:
- GTK strictly depends on PangoCairo internally
- we want to integrate the GDK docs with PangoCairo's
So even though we don't have an explicit dependency on PangoCairo types
in our ABI, we do assume that people will be able to use the PangoCairo
API with GTK.
Instead of bending GtkGizmo to the breaking point,
split off a GtkPanedHandle class that just does
what is needed here. Its simpler, and lets us keep
GtkGizmo simpler too. Everybody wins.
Instead of bending GtkGizmo to the breaking point,
split off a GtkPopoverContent class that just does
what is needed here. Its simpler, and lets us keep
GtkGizmo simpler too.
Rearrange our build to create a libgtk.a for the the contents of gtk/,
and build libgtk-4.so from our per-subdirectory static libraries.
This will let us link tests statically for testing internal apis.
This comes complete with animation support. For a good time, try:
@keyframes conic {
100% { background-image: conic-gradient(from 1turn, red, lime, blue, yellow, red); }
}
window {
background-image: conic-gradient(red, lime, blue, yellow, red);
animation: conic infinite linear 5s;
}
We depend on GObject, which already depends on GLib; on older versions
of Meson, this ends up trying to depend on the system copy of GLib,
instead of the sub-project copy, in case the version of GLib we have
installed is too old.
The GtkPlacesOpenFlags enum is only used in private
API, so move it to private headers. Since we still need
a GType for it, add gtkplacessidebarprivate.h to the
headers we use for generating private enum types. In turn,
this registers the other private enums in that header, so
take the opportunity to fix their naming, and use the
generated types for the corresponding sidebarrow properties.
Fixes: #3337
And generate the code for the DBus interfaces.
We don't want the full object manager experience, here, because we're
going to have a single object responding to various interfaces and
remote method calls. For this reason, we're not using the gnome module
in Meson to call gdbus-codegen for us: we need to use the interface info
command line arguments, and those are not available from Meson.
Like we do for GdkX11. We can't use all of the public C API, but we can
expose enough type information to allow non-C developers to actually
check if they are running the Wayland GDK backend or not—plus some
additional Wayland-specific API.
For the various uses of GDK_WINDOWING_QUARTZ, we need to use
alternatives from GDK_WINDOWING_MACOS.
Some minor loss of functionality is here, such as icons sent with
application menus. That can certainly be added back at a future
point.
Use the data files from https://github.com/milesj/emojibase.git
as source for our Emoji data. Slightly change our data format by
adding a group to each item, in both the Emoji data and in the
setting for recent-emoji.
Install translated versions of the data as separate resource
bundles in $prefix/gtk-4.0/emoji, and load them when appropriate.
Currently, we have data for de, en, es, fr, zh, with data taken
from Unicode 13 and CLDR 13.
Fixes: #950#1511
Yielding option means that if pango is built as a subproject, it will
take the value of that option from the parent project (e.g. gst-build).
For that to work it must be of the same type, which is "feature" instead
of "boolean" in all GStreamer modules.
Use the Windows API CryptProtectMemory() to encrypt the data that we want to
secure, and use CryptUnprotectMemory() to de-crypt the secured data that we
want to access, since mmap() and mlock() are not available on Windows.
We have a widget for password and passphrase entries, but we have no way
to handle the data securely. This is usually performed by a separate
GtkEntryBuffer—for instance, the one in GCR. While we have API for
setting a new entry buffer on GtkText, we don't have API for
GtkPasswordEntry, though, so the options are:
- expose additional API for GtkPasswordEntry to allow setting a secure
text buffer on the internal GtkText widget
- provide a secure text buffer out of the box
Given that an insecure-by-default GtkPasswordEntry is basically
pointless, might as well have a secure buffer built in.
We don't really need to make the password entry buffer public out of the
box, but we can re-evaluate at a later date.
Fixes: #2403
Use feature options for things that are optional features,
update the docs.
Visible changes here is that the 'print-backends' option
got renamed to 'print' to go better with 'media', and the
'tracker3' option got renamed to 'tracker'.
For options that have been changed into features, the
syntax now is -Dfeature=enabled or -Dfeature=disabled
or -Dfeature=auto.
We want to test the accessibility API, as well as the implementation
inside each widget. For that, we should expose an API that lets us
verify that a GtkAccessible has a given role, as well as a given
property.
The API follows the pattern of other GTest API:
- a macro to assert that a condition is respected
- a function that prints out the error message in case of failure
While we have split the various attributes for convenience, there's no
reason why we should have specialised data types for the attributes
container object.
The ATContext type is meant to be used as the base class for
implementations of the assistive technology API—the actual mechanism
needed to communicate to components like the screen reader, or any other
AT.
Every time the widget state changes, the ATContext is meant to broadcast
the state change; and every time the AT queries the state of a UI
element, the ATContext is meant to provide that information.
We also have a "test" ATContext implementation, which is meant to be
used to write tests to verify that changes are propagated without
requiring a whole desktop session.
All accessible properties and states may have one of the following
types:
- true/false
- true/false/undefined
- true/false/mixed/undefined
- reference (to another UI element)
- reference list
- integer
- number (real numerical value)
- string
- token (one of a limited set of allowed values)
- token list
See: https://www.w3.org/WAI/PF/aria/states_and_properties#propcharacteristic_value
The GtkAccessibleValue is a simple reference counted type that can be
"subclassed" to implement each value type.
This initial commit adds GtkAccessibleValue and the basic subclasses for
plain boolean, tristate (true/false/undefined), and token types,
including statically allocated values that can be shared instead of
allocated.
GtkAccessible is an interface for accessible UI elements.
Currently, it doesn't do much except exist as a type; in the future, it
will be the entry point for all accessible state in GTK.

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:
- it maps to a very specific implementation, AT-SPI, which is Linux and
Unix specific
- it requires implementing the same functionality in three different
layers of the stack: AT-SPI, ATK, and GTK
- only GTK uses it; every other Linux and Unix toolkit and application
talks to AT-SPI directly, including assistive technologies
Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:
- add an "accessible" interface, implemented by GTK objects directly,
which describe the accessible role and state changes for every UI
element
- add an "assistive technology context" to proxy a native accessibility
API, and assign it to every widget
- implement the AT context depending on the platform

GtkSortKeys is an immutable struct that can be used to manage "sort
keys" for items.
Sort keys are memory that is created specifically for sorting. Because
sorting involves lots of comparisons, it's a good idea to prepare the
data relevant for sorting in advance and sort on that data.
In measurements with a PropertyExpression on a string sorter, it's about
??? faster
