GNOME Accessibility
Accessibility Toolkit (ATK) is an open source software library, part of the GNOME project, which provides application programming interfaces (APIs) for implementing accessibility support in software. One common nomenclature to explain an accessibility framework is a usual client-server architecture. In that way, assistive technologies (ATs) such as screen readers, would be the clients of that framework, and computer applications would be the server. In this architecture the client and server need to communicate with each other, usually using the IPC technology of the platform. Ideally the accessibility framework expose this to the client and server in a transparent way. Usually the API for both client-side and server-side applications are the same, and the accessibility framework provides a client-side and a server-side implementation of that API. In the case of GNOME, there are two different APIs, one for the client-side ( Assistive Technology Service Provider Interface ( ...

GNU LGPL
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the MIT L ...

Header File
An include directive instructs a text file processor to replace the directive text with the content of a specified file. The act of including may be logical in nature. The processor may simply process the include file content at the location of the directive without creating a combined file. Different processors may use different syntax. The C preprocessor (used with C, C++ and in other contexts) defines an include directive as a line that starts #include and is followed by a file specification. COBOL defines an include directive indicated by copy in order to include a copybook. Generally, for C/C++ the include directive is used to include a header file, but can include any file. Although relatively uncommon, it is sometimes used to include a body file such as a .c file. The include directive can support encapsulation and reuse. Different parts of a system can be segregated into logical groupings yet rely on one another via file inclusion. C and C++ are designed to leverag ...

GUADEC
GUADEC, formerly the GNOME Users And Developers European Conference, is an annual developer conference whose prime topic is the development of the GNOME desktop environment and its underlying base software such as GTK, GStreamer GStreamer is a Pipeline (computing), pipeline-based multimedia framework that links together a wide variety of media processing systems to complete complex workflows. For instance, GStreamer can be used to build a system that reads files in one f ..., etc. The first GUADEC was organised by Mathieu Lacage as a one-off event and attracted around seventy GNOME contributors. It was the first time many of them had met in person. The conference was judged a success, and has been held annually in different locations since then, organised by local volunteers. The size has increased five-fold since the first conference. Conference history See also * List of free-software events Libre Application Summit References External links Official web siteMore ...

GUI Widget
A graphical widget (also graphical control element or control) in a graphical user interface is an element of interaction, such as a button or a scroll bar. Controls are software components that a computer user interacts with through direct manipulation to read or edit information about an application. User interface libraries such as Windows Presentation Foundation, Qt, GTK, and Cocoa, contain a collection of controls and the logic to render these. Each widget facilitates a specific type of user-computer interaction, and appears as a visible part of the application's GUI as defined by the theme and rendered by the rendering engine. The theme makes all widgets adhere to a unified aesthetic design and creates a sense of overall cohesion. Some widgets support interaction with the user, for example labels, buttons, and check boxes. Others act as containers that group the widgets added to them, for example windows, panels, and tabs. Structuring a user interface with widget ...

GUI Toolkit
A widget toolkit, widget library, GUI toolkit, or UX library is a library or a collection of libraries containing a set of graphical control elements (called ''widgets'') used to construct the graphical user interface (GUI) of programs. Most widget toolkits additionally include their own rendering engine. This engine can be specific to a certain operating system or windowing system or contain back-ends to interface with multiple ones and also with rendering APIs such as OpenGL, OpenVG, or EGL. The look and feel of the graphical control elements can be hard-coded or decoupled, allowing the graphical control elements to be themed/ skinned. Overview Some toolkits may be used from other languages by employing language bindings. Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup language such as in this case GtkBuilder. The GUI of a program is commonly constructed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assistive Technology Service Provider Interface
Assistive Technology Service Provider Interface (AT-SPI) is a platform-neutral framework for providing bi-directional communication between assistive technologies (AT) and applications. It is the ''de facto'' standard for providing accessibility to free and open desktops, like Linux or OpenBSD, led by the GNOME Project. One common nomenclature to explain an accessibility framework is a usual client-server architecture. In that way, Assistive Technologies (ATs), such as screen readers, would be the clients of that framework, and computer applications would be the server. In this architecture, client and server need to communicate with each other, usually using the IPC technology of the platform. Ideally the accessibility framework exposes this to the client and server in a transparent way. Usually the API for both client-side and server-side applications are the same, and the accessibility framework provides a client-side and a server-side implementation of that API. In the case ...
