NAME

       libloginhelper - Login-Helper library for assistive technologies

DESCRIPTION

       An interface for use by assistive technologies by which they can access system information and services on a 'need to know' basis while the
       screen is locked, during user authentication, or during other sensitive operations.

       This interface is intended for use by assistive technologies and related user-enabling services, and by applications  and  utilities  which
       may wish to restrict access to certain system devices and services during security-sensitive states, e.g. when the screen is locked or dur-
       ing authentication into some secure service.

       Such 'applications' (for instance, screen lock dialogs and security-enabled web browsers) use the LoginHelper client  interfaces,  and  the
       bonobo-activation query service, to query for assistive technologies which advertise the LoginHelper service. The client then queries these
       assistive technologies for their device I/O requirements, via the getDeviceReqs call. The client may then issue the advisory  request  set-
       Safe (TRUE), which requests that the LoginHelper -implementing service make a best-effort attempt to make itself more secure (for instance,
       an onscreen keyboard might turn off word prediction, and a screenreader may turn off keyboard echo via speech). The return value of setSafe
       is  an advisory indication of whether this attempt was successful (no specific guarantees are implied). Once the 'security sensitive' state
       is exited, the client should call setSafe (FALSE).

       The return values from getDeviceReqs inform the client of which services the LoginHelper service (e.  g.  assistive  technology)  needs	in
       order  to  do  its  job. The client may use this information to loosen any restrictions on access which it may currently have in place (for
       instance, keyboard grabs, etc.). If it does not do so, the likely outcome is that the end-user will experience loss of access to  the  sys-
       tem.

NAME

       libatk-1.0 - Accessibility Toolkit API

DESCRIPTION

       ATK  (Accessibility  Tool  Kit) is a set of interfaces which, when implemented by applications and user-interface component libraries, sup-
       ports the use of applications by persons with disabilities.  ATK provides a consistent set of in-process interfaces which conforming compo-
       nents implement, either directly or via the use of add-on libraries. These interfaces are in turn exported out-of-process for use by assis-
       tive technologies (see at-spi(3)).

       Using ATK, applications can explicitly provide descriptive information about their components. By using ATK-enabled toolkits such as  GTK+,
       applications obtain built-in accessibility support.

       The  ATK  API  is a queryable, interfaced API for obtaining textual, attribute-based, and coordinate information from user interface compo-
       nents, and also provides a means of activating and interacting with those components without the direct	use  of  the  keyboard	or  system
       pointing device.

       To access the API documentation, you must install the developer version of the package.
