gtk_widget_set_visible and gtk_window_present
are better alternatives, and calling gtk_widget_show
on newly created widgets is no longer necessary
anyway.
Move the implementations from gtksnapshot.c to
gtk/deprecated/gtkrender.c and deprecated these
functions. We want to get rid of them.
These functions are still used in some of our widgetry,
so use G_GNUC_BEGIN/END_IGNORE_DEPRECATIONS around
them.
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
We want to find focusable children, so we need to look at
the focusable property, not at can-focus. This is a change
from GTK 3, where can-focus was the correct property to
look at.
Set the SELECTED state to reflect whether the selected
is selected, unselected, or unselectable. This is
enough to make selection changes appear in Accerciser.
While we are at it, also set the multi-selectable
property for the flowbox itself.
Make GdkEvents hold a single GdkDevice. This device is closer to
the logical device conceptually, although it must be sufficient for
device checks (i.e. GdkInputSource), which makes it similar to the
physical devices.
Make the logical devices have a more accurate GdkInputSource where
needed, and conflate the event devices altogether.

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

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.
The api contract for size_allocate() vfuncs is
that they must allocate all the children that are
going to be snapshotted in snapshot(). The flowbox
size_allocate() was just bailing out when the children
request a size of 0x0, leading to an assertion in
snapshot() vfunc later. Just allocate all children
a size of 0x0 in this case.
This was only living in gtkcontainer.c for historic
reasons. Move it closer to where it belongs, and
rename it from 'idle' to 'layout', since it is
really about the layout phase of the frame clock,
nowadays.
Without this, it seems impossible to make cross-section
keynav in the Emoji chooser work. I've tried, but got
lost between the focus, grab_focus, move_cursor and
keynav-failed vfuncs and signals, and their competing
implementations GtkFlowBox and GtkEmojiChooser.
This commit handles complicated cases where we selections.
We handle this by adding extend and modify parameters to
the ::move-cursor signals, and adjust the bindings
accordingly.
Reviewing the existing settings, the only backend with
some differences in the modifier intent settings is OS X,
and we would rather have that implemented by interpreting
the existing modifiers in the appropriate way.

primary ctrl ctrl ctrl mod2
mnemonic alt alt alt alt
context menu - - - ctrl
extend sel shift shift shift shift
modify sel ctrl ctrl ctrl mod2
no text alt|ctrl alt|ctrl alt|ctrl mod2|ctrl
shift group varies - - alt
GTK now uses the following modifiers:
primary ctrl
mnemonic alt
extend sel shift
modify sel ctrl
no text alt|ctrl
The context menu and shift group intents were not used
in GTK at all.
Update tests to no longer expect <Primary> to roundtrip
through the accelerator parsing and formatting code.
