Applications using any of these widget libraries typically specify the content of the window before entering the main loop and do not need to explicitly handle Expose events and redraw the window content. The XCB library is an alternative to Xlib. Its two main aims are: reduction in library size and direct access to the X11 protocol.
X Toolkit Intrinsics (also known as Xt, for X toolkit) is a library that implements an API to facilitate the development of programs with a graphical user interface (GUI) for the X Window System. It can be used in the C language (or any language that can use the C API, such as C++). Design took place late 1980s to early 1990s. [citation needed]
X11-clients use XCB to communicate with the X server. A more complete view of the Linux graphics stack Programs often use GTK or FLTK or Qt for their GUI widgets. A more complete view of the components of an operating system for home computers. XCB (X protocol C-language Binding) is a library implementing the client-side of the X11 display ...
X.Org Server is the free and open-source implementation of the X Window System (X11) display server stewarded by the X.Org Foundation. Implementations of the client-side X Window System protocol exist in the form of X11 libraries, which serve as helpful APIs for communicating with the X server. [4] Two such major X libraries exist for X11.
The X11 protocol actually uses a single 32-bit unsigned integer - called a pixelvalue - for representing a single color in most graphic operations. When transferring the intensity of primary colors, a 16 bit integer is used for each color component. The following representations of colors exist; not all of them may be supported on a specific ...
The X Window System (X11, or simply X; stylized 𝕏) is a windowing system for bitmap displays, common on Unix-like operating systems. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. [ 3 ]
X Athena Widgets or Xaw is a GUI widget library for the X Window System. Developed as part of Project Athena , Xaw was written under the auspices of the MIT X Consortium as a sample widget set built on X Toolkit Intrinsics (Xt); Xt and Xaw are collectively known as the X Toolkit. [ 1 ]
GDK (GIMP Drawing Kit) is a library that acts as a wrapper around the low-level functions provided by the underlying windowing and graphics systems. GDK lies between the display server and the GTK library, handling basic rendering such as drawing primitives, raster graphics (bitmaps), cursors, fonts, as well as window events and drag-and-drop functionality.
