Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=793124
This code was doing horrible things, and the atk documentation
for the focus tracking feature says that this is deprecated and
not used anymore. So lets not do it.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=779009
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.
Instead of returning the icon size with them, make
gtk_image_get_icon_name() and gtk_image_get_gicon() only return the icon
itself.
As a benefit, we can turn them into regular getters that return values
instead of requiring out parameters.
Instead, provide gtk_image_get_icon_size() to query the icon size.
A sideeffect is that we don't set the correct parent window on child
widgets anymore, but that is hopefully going to be fixed once we get rid
of child windows completely.
These are no longer used, instead we always covert to surface as
early as possible and drop the pixbuf.
This means we never store both the pixbuf and the surface at
for any longer time, which is wasteful. Also, its one step further
to drop GdkPixbufs from generic use in our APIs.
This drops the pixbuf property and the pixbuf getters. We keep
gtk_image_new/set_from_pixbuf, but these are small helpers that
immediately convert to a surface, and there is no way to later get
back the pixbuf you passed in.
The from file/resource codepaths are also changed to load a surface
instead of a pixbuf.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=784509
This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=774939
This is a problematic struct, and giving direct access to it
has kept us from making improvements to GtkTextView. Drop it
from the public API, together with the auxiliary APIs. If
it turns out that this functionality is needed, we should add
individual getters.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=695375
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.
The code path where we update the tooltip text property doesn't set
the state and value variables, and so doesn't need to call
notify_state_change().
Return early, and move the if block at the beginning of the function for
clarity.
Expose GtkEntry icons as child accessibles of a GtkEntry, and provide
actions to simulate clicking them. Also, refactor the a11y children test
slightly to add a test.
https://bugzilla.gnome.org/show_bug.cgi?id=686347
Move instance fields to a private struct, in preparation
for installing a11y headers.
This also required removing access to GtkWidgetAccessible innards
from several accessible implementations.

I'll add a bunch of fixes for gcc complaining about
-Wmissing-declarations after finding a bunch of cases today where I had
forgotten to make functions static in the CSS code.
A thorn in those patches is G_DEFINE_TYPE() which doesn't allow making
the get_type() function static, so I added definitions for that function
above the G_DEFINE_TYPE().
After those patches, GTK should compile without warnings when this flag
is enabled.
Call _gtk_entry_get_display_text()from gtkentryaccessible.c to make
sure we always consider the actual text being displayed when
implementing the functions from the AtkTet interface.

Some builders using gtk3 outside of the GNOME cycle want an option to
avoid linking to atk-bridge-2.0. Provide that, and at the same time
ensure we're only looking for it on X11 platforms.
https://bugzilla.gnome.org/show_bug.cgi?id=677491
If we use
&item->cell_area
instead of
(GdkRectangle *) item
there is no need anymore to keep the cell_area as the first member of
the the item. And we cget compile-time checks for changes to the item
struct.
use direct access to the RBTree instead of fiddling with the path.
Removes the lat caller of get_index() and with it count_rows(), so those
are gone now.
Refcounting behavior kinda requires that we track of accessibles until
the row goes away. This is necessary for reference handling and for some
assumptions that atk-bridge does.
This reverts commit 0c8ecba7dc.
The change broke Orca completely, and we need a proper fix first.
So we have to live with the bugs intorduced by this until then.
As previously announced, key snooping is something that we should not
support in GTK. In particular because AT-SPI made every key press a
synchronous DBUS call / spawned a nested main loop with the key
snoopers. This breaks responsiveness, order of key presses and internal
consistency when the AT decides to remove key events.
1) always emit signals
Previously, newly constructed cells would be told to not emit events.
However, we can ensure that nothing is connected to the signals, so
they will not actually emit anything.
2) don't return anything
The return value is unused anyway.
No more signal handler is needed, therefore the code can also get rid of
tracking the treemodel. And we use a faster approach for iterating the
changed cellrenderers: We just iterate all columns instead of over all
cell accessibles, as that number is likely quite a bit smaller.
Multiple changes:
- actions are now available unconditionally, but only work in the right
state. This mirrors other actions.
- instead of adding actions manually, they invoke the action on the
GtkCellAccessibleParent interface.
Tests have been updated to reflect the changes
_gtk_tree_view_find_path() was not a name that not really described what
the function does. And I kept forgetting it. Also, it took the tree view
as an argument and that was completely unnecessary.
Various tiny semantic changes in here.
The big fix is that we consider every cell as visible and as showing if
the treeview is mapped.
This was also fixed in the tree dump test.
There was some regressions from the recent display line fix;
while fixing it improve the test coverage and make GtkEntry
and GtkTextView return identical results.
This way, the a11y code knows if a column was reordered, added or
removed and can do the right things instead of trying to guess and
getting it wrong.
Also, this patch finalizes the changes so that only visible columns
exist to the accessibility interface.
In fact, invent our own function get_n_columns() which actually only
counts the visible functions, because that's the only ones we care
about.
The places where it's not used yet will be changed in the coming
patches.
Track the RBNode/RBTree instead of keeping a TreeRowReference. This is a
whole lot faster and less error-prone.
Also, notify the accessible of removal of rows before actually removing
them, so we have a chance to clean up.
Instead of requiring a special functio to be called before just removing
from the hash table. This simplifies code a lot that used to remove from
the hash table.
- Name it properly
- Make it just a set of cell_infos
Currently it's using direct hash, but as long as we don't actually
lookup stuff from it, who cares...
We implement get_cell_index() now, so it's no longer necessary.
As a side effect, we need a different index for our hash table (which
now has a wrong name, but that will soon change).
Ahem.
This is in preparation for future changes and is not meant to stay this
way. But I want to change the hash table's keys and this is way easier
when nobody is using them.
I could have tried to make GtkContainerCellAccessible implement
GtkCellAccessibleParent, but the current implementation of that
interface doesn't make sense for it.
This way, we can include them without accidentally including deprecated
code. Which means we can still use the recently added turning-off tricks
for deprecation warnings.
The following assertion was triggered in model_row_inserted() because
iterate_thru_children() modifies the parameter tree_model before passing it to
traverse_cells().
Gtk-CRITICAL **: gtk_tree_path_compare: assertion `b->depth > 0' failed
The stack with the bug was:
#0 gtk_tree_path_compare at gtktreemodel.c
#1 traverse_cells at gtktreeviewaccessible.c
#2 model_row_inserted at gtktreeviewaccessible.c
This patch calls iterate_thru_children() with a copy of the path so that the
original is not modified.
For god-knows-what reason, at-spi is trying various formats
of strings when registering listeners, triggering g_warnings()
from gailutil code. Stop doing that.
Also, don't leak temporary string arrays that are a side-effect
of passing parameters around as formatted strings.
