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
For more information, see: https://gitlab.gnome.org/GNOME/gtk/-/issues/2833
The differences between the existing properties and the newly added
GtkWidget:focus-on-click property are minimal (different owner_type
in GParamSpec), so it is extremely unlikely that dropping the former
would break anything.

- Passing a NULL ID string should be equivalent to
gtk_combo_box_set_active (combo_box, -1).
- Use g_strcmp0() instead of strcmp() when comparing
ID strings to avoid a crash when an ID is NULL.
- Return a boolean indicating if the ID was found or not.

Based on a patch by Matthias, add an "active-id" property for
GtkComboBox and add some convenience API for GtkComboBoxText.
Also, add a test case to gtk-demo.
This patch adds a GtkComboBox:popup-fixed-width to decide if the
popup's width should be a fixed width matching the combo's allocated width.
The patch includes a kindof hack to work around treeviews currently
not supporting height-for-width geometry (for list-mode only), this
hack can be safely removed once treeviews start reporting natural
widths properly.
GtkComboBox now sports a construct-only "has-entry" property which
decides if it uses a GtkEntry to allow additional user input. Also
it has a new "entry-text-column" to fetch strings for the entry
from the model.
This patch deprecates the GtkComboBoxEntry and updates the rest of GTK+
to use the new semantics on GtkComboBox instead.
GtkComboBoxEntry will be removed altogether before GTK+ 3, in a
later commit.
GtkCellEditable::editing-canceled property was added in 2.19 cycle,
so we should make the code that currently uses entry->editing_canceled
directly go through the property

Bug 382291 – Automatically dim the combobox when the model is empty
* gtk/gtk.symbols:
* gtkcombobox.[hc]: Add a GtkComboBox::button-sensitivity
property with getter and setter to control the sensitity of
empty combo boxes. Patch by Carlos Garnacho, Sven Herzberg,
Christian Dywan and others.
* README.in: Add a note about automatic combobox sensitivity.
svn path=/trunk/; revision=20997
2008-05-28 Michael Natterer <mitch@imendio.com>
* gtk/gtk.h: define __GTK_H_INSIDE__ around including all other
headers.
* gtk/gtktypebuiltins.h.template
* gtk/gtkversion.h.in
* gtk/gtk*.h: add single-include guards that #error out if
GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
included individually.
* gtk/gtkprintbackend.h
* gtk/gtkprinter-private.h
* gtk/gtktextlayout.h
* gtk/gtktexttagprivate.h
* gtk/gtktexttypes.h
* gtk/gtktreedatalist.h: include <gtk/gtk.h> instead of individual
headers in these private or semi-private headers.
* gtk/gtkimmodule.h: also here because it's not in gtk.h.
* gtk/gtkpagesetupunixdialog.h
* gtk/gtkprinter.h
* gtk/gtkprintjob.h
* gtk/gtkprintunixdialog.h: likewise in the gtkunixprint headers.
* gtk/gtkclist.h
* gtk/gtkcombo.h
* gtk/gtkctree.h
* gtk/gtkfilesel.h
* gtk/gtkitemfactory.h
* gtk/gtklist.h
* gtk/gtklistitem.h
* gtk/gtkoldeditable.h
* gtk/gtkoptionmenu.h
* gtk/gtkpixmap.h
* gtk/gtkpreview.h
* gtk/gtksignal.h
* gtk/gtktipsquery.h: whenever possible, include only <gtk/gtk.h>
instead of individual headers in these deprecated headers. They
don't get included at all when GTK_DISABLE_DEPRECATED is defined,
so if an app needs them anyway, it must undef GTK_DISABLE_DEPRECATED
and include them individually, which should continue to work.
* gtk/gtkclist.c: include "gtkctree.h" because of the change
above.

Make gtk_combo_box_get_active_text do the right thing for
GtkComboBoxEntry (#171373, Robert Staudinger)
* gtk/gtkcombobox.h: Add a get_active_text vfunc.
* gtk/gtkcombobox.c (gtk_combo_box_real_get_active_text): And
implement it here.
* gtk/gtkcomboboxentry.c (gtk_combo_box_entry_get_active_text):
Implement get_active_text by always returning the content of
the entry.

Fix#150125:
* gtk/gtkcombobox.[hc]: Add a ::focus-on-click property and
change the default behaviour to focus on click.
* gtk/gtkbutton.c (gtk_button_set_focus_on_click): Typo fix.
2004-07-30 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkcombobox.h:
* gtk/gtkcombobox.c: Change the api for separators to use a
separator function instead of a boolean column.
* tests/testcombo.c: Update to match the api change.

function necessary to make GtkComboBox accessible. (#132847,

Support separators in combo boxes and more generally in tree
views (#135873):
* gtk/gtkcombobox.h:
* gtk/gtkcombobox.c (gtk_combo_box_get_row_separator_column):
* gtk/gtkcombobox.c (gtk_combo_box_set_row_separator_column):
Add a ::row-separator-column property with getter and setter,
which can indicate a boolean model column to determine which
rows are separators.
* gtk/gtkcombobox.c: Display separator rows as separator menu
items in menu mode, and by using the new treeview separator
functionality in list mode.
* gtk/gtktreeview.h:
* gtk/gtktreeview.c (gtk_tree_view_get_row_separator_func):
* gtk/gtktreeview.c (gtk_tree_view_set_row_separator_func):
Add a callback to determine whether a row is a separator.
* gtk/gtktreeview.c (gtk_tree_view_bin_expose):
* gtk/gtktreeview.c (gtk_tree_view_create_row_drag_icon):
* gtk/gtktreeview.c (validate_row): Use the new callback
to determine whether a row is a separator, and draw it
as a separator then. Since separators should take up less
vertical space than regular rows, this requires removing
the redundant MAX(...,expander_size) calls which appear in
many places. Instead, the MAX() is now only done in
validate_row(), and only if the row is not a separator.
To catch possible side effects of this intrusive change,
I have left EXPANDER_MAX() calls in place of the MAX() calls
which will emit a warning if something breaks. They should
be removed before 2.6.
* gtk/gtktreeselection.c (row_is_selectable): Don't let
separator rows be selected.
* tests/testcombo.c (create_blaat): Add a separator column.
