Note that GAIL does automatically create RELATION_LABELLED_BY/RELATION_LABEL_FOR labels and widgets which are attached next to one another in table layouts. Specify relationships between labels and controls and between groups of controls using atk_relation_new() and atk_relation_set_add().Provide names and descriptions of some controls and images using atk_object_set_name and atk_object_set_description() or atk_image_set_description().When using the GTK+ widget set, most accessibility information is built into the widgets by GAIL except for doing the following: The ATK bridge exports ATK to AT-SPI for GTK+ applications.

The ATK library provides all the accessible object classes (based on GObject) and the interfaces the accessible objects implement (based on GInterface).ДЄTK is an in-process accessibility API, written to by applications and implemented for GTK+ widgets by GAIL (GNOME Accessbility Implementation Library), which a GTK application dynamically loads at runtime if the value of the accessibility gconf key (/desktop/gnome/interface/accessibility) is 'true.'ДЄT-SPI is an out-of-process CORBA API implementation used by assistive technologies. The Pango engine and library provides functions for text layout and rendering, with internationalization considerations.

A theme can either be simply a set of colors and pixmaps used by the existing drawing code or it can be a complete replacement of the functions used to draw widgets. Without recompiling either GTK+ or the application, users can choose a new look for their applications by installing a new theme. User-interface customization is accomplished using themes. The GTK+ Object System provides a library and class hierarchy of objects (including widgets, containers, windows) with features that include inheritance, polymorphism and reference counting, signal notification, and attributes.Дrag and drop interfaces support the Motif or Xdnd Drag and Drop protocols.

The GDK library provides an abstraction layer between the GTK+ widgets in an application and the underlying X window system. The GLib library provides portability and convenience functions, generic data structures, and the GLib main loop. The GTK+ accessibility architecture depends on a number of libraries and interfaces for programming a GTK+ application, and for making the objects and interfaces accessible, translatable, and usable: GTK+ and ATK - A Foundation for GNOME AccessibilityДЇIGURE 1.0 GTK+ Accessible Application Architecture
