Those property features don't seem to be in use anywhere.
They are redundant since the docs cover the same information
and more. They also created unnecessary translation work.
Closes#4904
The swipe gesture forces values in the spin button that are
"impossible" according to the adjustment. This can break things
in creative ways.
Ensure the steps provided are always multiples of the adjustment
step value, and keep the remainder for further interaction.
In the GTK3 days, the spin button was an entry, with buttons on
top, and the swipe gesture affected the input on the entry bits.
Now the spin button is a container, so this gesture in the capture
phase applies to all contained children (incl. buttons).
Attach this gesture to the entry itself, so the buttons are left
outside this business. The gesture is still in the capture phase
in order to prevent text selection/edition/etc to happen.

Remove a boatload of "or %NULL" from nullable parameters
and return values. gi-docgen generates suitable text from
the annotation that we don't need to duplicate.
This adds a few missing nullable annotations too.
Orca ignores events unless the object is inside an object
with role window and states ACTIVE and SHOWING. To arrange
for this, introduce a new ACTIVE platform state, and set it
for windows when they are active.
This gets orca to be a lot more talkative.
The buttons here are not really buttons (the action
is not tied to the "clicked" signal), so triggering
the buttons via a11y does not have the expected effect.
And we expose the Value interface that ATs can use
to set the value.
This copies what was done for GtkEntry: get
the focused state from the GtkText within.
We also add a private getter for the text widget,
which was missing here.
We are adding click gestures on the up/down buttons, but can't let
the GtkButton built-in ones prevent ours to run.
As the saying goes, if you can't beat them, join them. Group the
spinbutton and GtkButton gestures together, so it's irrelevant which
gets called first and ends up winning.

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

We lost this when GtkSpinButton was first ported
to the new editable regime, and then the GtkBoxLayout.
Bring it back, but without text measurement, by overriding
width-chars for the GtkText inside, and only do it if
GtkSpinButton::width-chars is unset (ie -1).
Also adjust the documentation slightly to point out
how auto-sizing can be turned off.
It feels slightly wrong to have GtkOrientable operate on widgets, but at
least what happens when an orientable widget changes orientation should
be part of GtkWidget.
This will allow to add more state changes without accessing widget state
from the outside of gtkwidget.c.
After the :can-focus change in the previous commit, widgets
need to set suitable focus and grab_focus implementations
to implement the desired focus behavior.
This commit does that for all widgets.
Split the focus tracking into a separate
GtkEventControllerFocus, and change the API one more time.
We are back to having ::focus-in and ::focus-out signals.
Update all users.
Instead of relying on gdk's antiquated crossing events,
create a new GtkCrossingData struct that contains the
actual widgets, and a new event controller vfunc that
expects this struct. This also saves us from making sense
of X's crossing modes and details, and makes for a
generally simpler api.
The ::focus-in and ::focus-out signals of GtkEventControllerKey
have been replaced by a single ::focus-change signal that
takes GtkCrossingData as an argument. All callers have
been updated.
