To build a better world sometimes means having to tear the old one down.
-- Alexander Pierce, "Captain America: The Winter Soldier"
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

In 99.9% of all cases, these are just NULL, NULL.
So just do away with these arguments, people can
use the setters for the rare cases where they want
the scrolled window to use a different adjustment.
Use window title, or custom title widget if it's set. Remove 'title'
property.
Update demos and tests to set the title on the window instead of
headerbar.
This makes meson actually parse the individual test
results. Most of the time, it does not make a difference,
but one case where it does is when all the individual
tests of a binary are skipped, meson will mark the
test as skipped.
It is enough to just set the parent (and make the parent
call gtk_native_check_resize in size_allocate).
This commit removes the relative_to argument to the
constructors of GtkPopover and GtkPopoverMenu, and
updates all callers.
All the a11y tests were failing for me with a window state diff
like this:
- state: active enabled resizable sensitive showing visible
+ state: enabled resizable sensitive showing visible
I guess the windows in the CI always gets the focus, but not when
I run it here. Generally focus seems asynchronous and hard to rely
on so I just made the test ignore the active state on toplevels.
This adds a GDK_DEBUG=default-settings flag which disables reads
from xsettings and Xft resources, and enables this for the testsuite.
This is one less way to get different testresults depending on the
environment. In particular, it was failing the css tests for me
due to getting the wrong font size because i have a different dpi.
The calls used old bugzilla URLs and nobody cared about that.
So apparently they are very unused.
There's also a potential conflict between gitlab and bugzilla URLs and
what base bug to use there.
The old usages have been converted to comments.
The position child property is problematic, since it
requires us to emit notification for all children when
inserting a child early in the list of children.
Remove the property from all ui files.
Keep in sync with the current tree.
The changes are mostly caused by updates in the internal hierarchy of
composite widgets, and the fact that the order in which the widget tree
is traversed is not exactly stable.
Instead of having a single massive test running through the a11y
directory, we can split off each individual file into its own unit.
Having individual units has several advantages:
- units are executed in parallel
- it's easier to identify the failing units
- logs for failed units are easier to read
This allows to override the role declared to the atk stack. For
instance,
<accessibility>
<role type="static"/>
</accessibility>
allows to tell the accessibility stack that a label is just a message in
a message box.
Fixes#109
With autotools the schemas were compiled into each test suite directory
and the tests set GSETTINGS_SCHEMA_DIR to the test build directory.
With meson's gnome.compile_schemas() we can not define a target directory
so just make sure it is built in the gtk directory and set GSETTINGS_SCHEMA_DIR
to the gtk build directory when running the tests.
This makes the gtk+:gtk suite pass when no gtk is installed on the system.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_idle() and
gdk_threads_add_idle_full() exist is to allow invoking a callback with
the GDK lock held, in case 3rd party libraries still use the deprecated
gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing idle callbacks.

That is some old code that still uses IOChannels, and the only
pseudouser is at-spi-atk's commented out code that is still using
CORBA types.
So get rid of it now before I need to start adapting it to the new
clipboard.
