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.
https://bugzilla.gnome.org/show_bug.cgi?id=746706
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.
https://bugzilla.gnome.org/show_bug.cgi?id=746706
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.
https://bugzilla.gnome.org/show_bug.cgi?id=746586
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.
The next call to gtk_list_box_get_selection_mode just expected the
GtkListBoxRow's parent to be a GtkListBox and failed when the row was
added to something other than a GtkListBox.
https://bugzilla.gnome.org/show_bug.cgi?id=733782
The signal needs to be emitted after the text insertion as at-spi gets
the text to compute the inserted text due to the AtkText::insert-text
signal not containing it.
Also adjust position to reflect changes to the offsets.
https://bugzilla.gnome.org/show_bug.cgi?id=731429
This way, we don't create lots of cell accessibles when creating the
first one (because surely one is the parent/child of another who again
is a parent/child of another who again....)
Nobody was reffing those related object in the first place and that
was causing random crashes.
And if somebody had reffed those related objects, they'd have caused
reference cycles.
https://bugzilla.gnome.org/show_bug.cgi?id=726838
And let GtkPopover use it as its GtkAccessible implementation, this
accessible sets the POPUP_FOR relationship to the relative-to widget,
and keeps track of changes there.
https://bugzilla.gnome.org/show_bug.cgi?id=725864
Old code assumed that AT-SPI would keep track of references and
therefore tried to only hold weak references. On the other hand it also
tried to keep objects alive so it referenced objects very randomly. All
of that lead to cycles and leaking.
As AT-SPI does not keep track of objects at all, the treeview now does.
The refcounting looks as follows:
GtkTreeViewAccessible
=> creates per row/column
GtkTreeViewAccessibleCellInfo
=> which references 1
GtkCellAccessible
If there is only one cell, this accessible is a
GtkRendererCellAccessible, otherwise a GtkContainerCellAccessible is
created and that accessible holds references to the
GtkRendererCellAccessibles that are created for every cell renderer.
https://bugzilla.gnome.org/show_bug.cgi?id=554618
GtkMenuItemAccessible was assuming that an accel label is
always the immediate child of a menu item. It also did not
deal with manually set accels. Fix both of these.
https://bugzilla.gnome.org/show_bug.cgi?id=721086
Improve the color swatch accessible to set a proper role
depending on whether the swatch is selectable or not, and
set the checked atk state when appropriate.
https://bugzilla.gnome.org/show_bug.cgi?id=721048
GtkModelMenuItem does not emit the ::toggled signal when a radio
item is activated, so listen for property notification for that
property. We still keep the ::toggled signal handler, in order
to not break other uses of check and radio menu items.
https://bugzilla.gnome.org/show_bug.cgi?id=720983
And update the colorchooser a11y test to a) use GtkColorChooser
instead of the deprecated GtkColorSelection and b) match this
change. Pointed out in
https://bugzilla.gnome.org/show_bug.cgi?id=721045
This commit makes the label accessible implement AtkHypertext,
which returns a AtkHyperlink object for each link in the text.
At the same time, add AtkHyperlinkImpl objects as children
to the label accessible.
Also some private API to indicate that links have changed, and
call that from GtkLabel when needed.
Adjust expected output of the affected a11y tests.
https://bugzilla.gnome.org/show_bug.cgi?id=721410https://bugzilla.gnome.org/show_bug.cgi?id=721421
The get_end_index implementation was casting the accessible
to AtkText even though GtkLinkButtonAccessible does not
implement this interface. This did not show up in the a11y
tests because the they were not dumping the affected AtkHyperlinkImpl
properties. Oops.
The button now claims its menu as a child for a11y purposes,
which makes it possible for ATs to see it when the navigate
the tree top-down.
Update the a11y test to match.
With the stock system being deprecated now, we should provide
meaningful accessible names for buttons that are constructed
from icon names or GIcons. This commit reuses the existing
translations.
It is possible that some common icon names are not covered
here because they were not present as stock items. These can
be added to the table later.
GtkFlowBox is a container that its children in a reflowing
grid, which can be oriented horizontally or vertically.
It is similar to GtkListBox in that the children can
be sorted and filtered, and by requiring a dedicated child
widget type, GtkFlowBoxChild. It is similar to GtkTreeView
in that is supports a full set of selection modes, including
rubberband selection.
This is the culmination of work that has happened in the
egg-list-box module, and earlier in libegg. The origins of
this code are the EggSpreadTable in libegg, which was written
by Tristan van Berkom. It was moved to egg-list-box and
renamed EggFlowBox by Jon McCann, and I gave it some finishing
touched in the flowbox-improvements branch of that module.
This reverts commit 7cecc8e524.
It is impossible to use the selection object of the menu while it is
collapsed (collapsed menus deselect everything for a start), so even
though the original patch was correct, the followup issues are too big
to solve this quickly to a release.
https://bugzilla.gnome.org/show_bug.cgi?id=707786
A proper name or label is required. In the same way, if the
widget is labelled, ATs uses to expose both the label and the
name, making the final output not really user-friendly.
https://bugzilla.gnome.org/show_bug.cgi?id=707872
Call gtk_widget_get_mapped() in a couple of places before looking at the
widget's parent, since it might be set to a widget that has been
finalized, causing an invalid read.

Just as for GtkRangeAccessible, we were not even trying to disconnect
the signal handler from the adjustment. The same fix works here:
override the widget_set and widget_unset vfuncs.
https://bugzilla.gnome.org/show_bug.cgi?id=705692
We were only disconnecting the signal in finalize, when
the widget was already unset. Instead, override the widget_set
and widget_unset vfuncs of GtkAccessible, and keep a reference
to the adjustment.
https://bugzilla.gnome.org/show_bug.cgi?id=705692
AtkSelection requires that the immediate children of the object are the
selectable items. The combobox however is implemented with just 1 child:
The popup menu.
The popup menu is implementing the selectable interface.
Test are updated to reflect this change.
To clear the tooltip one is to set the tooltip to NULL. Though
the GtkEntryAccessible expect this tooltip to not be NULL in
gtk_entry_accessible_notify_gtk (already handling this case
in its _init).
Fixes:
** (epiphany:23914): CRITICAL **: atk_object_set_description: assertion
`description != NULL' failed
when epiphany g_object_set the entry icon tooltip to NULL (clear the
tooltip) in its find bar.

When setting new text on the label, the text-changed::delete signal
needs to be emitted before deleting the text (so that atk-bridge can
query the old text) while the text-changed::insert event needs to happen
afterwards (for the same reason). The old code using the notify signal
was only emitted after changing the text.
Update the Visual Studio projects for gtka11y and the completion of the
projects that go along with it. This have been distcheck'ed on my Ubuntu
12.04 system.
We don't want to emit state changes for all the cells in a row, just for
the cell in the expander column. It's the only one that reports EXPANDED
or EXPANDABLE states, after all.
Also, contains refactoring of the affected functions for all the special
cases.
https://bugzilla.gnome.org/show_bug.cgi?id=694059
We weren't checking the removed flag but the added flag for removal
emissions, so what would happen for every state change notification was:
- on state-added, both an "added" and a "removed" event were emitted
- on state-removed, nothing
https://bugzilla.gnome.org/show_bug.cgi?id=694059
The "activate" action here did not do anything.
It is possible we actually want to have some actions here,
like "step-up", "step-down", "page-up", "page-down", etc.
For now, just remove the AtkAction implementation.
https://bugzilla.gnome.org/show_bug.cgi?id=553334
-Rename the "libgail" projects to gtka11y, for consistency with the
autotools builds
-Update the projects completion in gtk/a11y/Makefile.am, as the sources are
now listed under $(libgtka11y_la_SOURCES) instead of $(libgail_la_SOURCES)
An instance of GtkAdjustment may be used by another instance after
the spin button widget is destroyed. In that case, the function
gtk_spin_button_accessible_value_changed() will be called with an
invalid argument. This situation is often caused when one use
GtkCellRendererSpin widget. To avoid invalid call of the function,
the signal handler for the "value-changed" signal should be disconnected
when the spin-button widget is destroyed.
Using g_signal_connect_object achieves just that.
https://bugzilla.gnome.org/show_bug.cgi?id=691592
Since we are going to install these headers soon, we need
to make their mutual includes work in the installed location
as well. Also, avoid including individual gtk headers, to
avoid trouble with single-include guards.
This commit exposes the get_type() functions and standard
headers for accessible implementations. This makes it possible
to derive from the GTK accessible implementations without
GType magic tricks. This is necessary, because we require the
a11y type hierarchy to be parallel to the widget type hierarchy.
So, if you derive a widget and need to adjust its a11y implementation,
you have to be able to derive its accessible implementation.
This commit probably exposes more than is absolutely necessary,
it also exposes accessibles of widgets that are unlikely candidates
for deriving from.
