GtkContainerCellAccessible wasn't unsetting accessible
parents. Fix that.
By itself, this doesn't help for freeing a memory leak,
since AtkObject keeps a ref on its parent, so we never
free the GtkContainerCellAccessible as long as it has children.
When the notebook page does not have a label, it should not fallback to
asking its child accessible for extent, since the child might be asking
exactly the converse when it is a socket, thus getting in an infinite
loop. When the page does not have a label, is does not really make sense to
give it an extent anyway.
Fixes atk#18
When a plug is embedded in a socket, we need to also plug the at-spi
tree, so that screen readers can find the at-spi content of the plugged
widgets.
This change does this plugging automatically: on the plug widget, an
additional _XEMBED_AT_SPI_PATH property is set to provide the at-spi path
(just like we have _XEMBED_INFO for other X11 information), and when
embedding it, the socket reads it, and makes it as its only child.
Since GtkPlugAccessible can not inherit both from AtkPlug (a child of
AtkObject) and from GtkContainerAccessible (a child of AtkObject), we
actually make GtkPlugAccessible a child of an AtkPlug, and that's what
will be embedded (in at-spi terms) into an AtkSocket.
Similarly, GtkSocketAccessible can not inherit both from AtkSocket and
GtkContainerAccessible, so we make it a parent of the AtkSocket that
embeds the AtkPlug.
This change depends on atk 2.35.1 which implements the at-spi technical
details.
This separates out atk-bridge-2.0 dependency, which is not part of atk,
but of at-spi2-atk.
This implementation is based on gtk_text_view_scroll_to_iter() and
thus shares its limitations for the sake of simplicity.
A single offset is opportunistically picked to build the iterator
needed for gtk_text_view_scroll_to_iter(). That means that substrings
spanning over multiple lines or larger than the current window might
not be displayed optimally after scrolling.
Partially closes#1625, the toPoint() variant has been discarded.
In the unlikely case that GTK is "embedded" with other toolkits
(hi, Mutter), GTK will clobber the embedder's AtkUtil implementation,
leaving its own a11y in a broken state.
AtkUtil is not meant to be overridden by multiple toolkits within a
single client, so the most sensible thing to do is stay away from it
if that is the case. This helps the embedder's a11y to win.
Fixes Clutter a11y in Mutter after xwayland-on-demand, process
startup used to be in a fixed order so that Clutter's a11y would
eventually win, but x11/gtk startup is now asynchronous and able to
happen at a later point.

including when the control modifier is present, i.e. when one is typing
control-I for instance.
Orca would convert them back to the corresponding ASCII letter anyway, and
when pressing control-tab, we do want to pass "tab", not pass "\t" that Orca
would erroneously convert to "control-I".
Fixes#1743
...since one of the "fixes" there was wrong, at least cosmetically:
.get_position() is declared as returning a gboolean, which is in fact an
int in practice, but we should say what we mean, like we already did.
Make sure that the return types of the vfuncs match the ones that are
specified for post-atk-2.11.x AtkTableCellIface, since we already
require atk-2.15.1 and later.
Calling the accessibility function `grab_focus()` on a `GtkCell` under
Wayland will cause the client to crash.
This is another case of `gdk_x11_get_server_time()` being called
regardless of the actual windowing backend used.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1507
`gtk_widget_accessible_grab_focus()` code checks that X11 isenabled at
build time and uses X11 specific functions such as
`gdk_x11_get_server_time()` regardless of the actual backend being used.
Check that we are using an X11 display when X11 is backend enabled, so
we do not crash when running on Wayland
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1507
The else case was wrongly resetting the accessible description on the
primary icon, which might not exist and can therefore cause a crash.

Use g_signal_connect_data() instead of g_signal_connect_object()
to make sure the callback gets disconnected when the data object
is destroyed. This avoids problems in garbage-collected bindings.

delete_range_cb is set to be called before the text suppression done by
the gtktextlayout (otherwise it does not work properly). But at that
point the cursor position is not yet up to date. We thus need to move
the accessibility cursor notification to after the actual text
suppression, by using another callback.
This fixes cursor position in brltty screen reading.
The second parameter of the text-changed::delete event is to be the length,
not the end position. This fixes spurious text removals in brltty
screen reading.
We need to notify ATK the description changed when the tooltip text associated
with the widget changes and gtk_widget_accessible_get_description() would use
it as the description.

What is missing is the "allocation" part of x/y coordinates. Since
gtk_entry_realize doesn't call gtk_widget_set_window(priv->text_area),
the coordinates returned by gdk_window_get_origin don't include it.
This patch fixes this.

Since at-spi-atk commit 96621a5e95 fixed PropertyChange notifications
for AccessibleParent, setting the parent will result in a call to
ref_state_set() which assumes that the object is fully initialized.

This is a workaround for atspi-atk behaviour.
atspi-atk uses signal emission hooks. So it to already catches
signal emissions on creation of objects, before anyone could even
think of g_signal_connect()ing.

Put the equality check in front. This allows better detection of when an
insert or delete needs to be emitted.
Also, only emit text-changed:delete if the deleted text is not the empty
string. Only emit text-changed:insert if the inserted text is not the
empty string.
https://bugzilla.gnome.org/show_bug.cgi?id=746706
Compute the new text and its length in advance. This way those
computations will not confuse us when they happen in the middle of the
actual action.

If the widget has been destroyed since a DBus message had been sent,
we could be in a condition that the widget pointer exists but it does
not have a window.
This bails as if the widget didn't exist if there is no available
GdkWindow.
We also set the extents to 0 to be defensive since this is a vfunc
implementation.

Rework the way we assign an accessible name to menu buttons,
to make sure we pick up a label, should the button contain
one, and only override the name with "Menu" as a fallback.
Gtk_container_cell_widget_set should chain up to its parent's set
function, not its parent's unset function. This was resulting in
accessibles being erroneously marked defunct after being created.
