X Resources
In the X Window System, the X resources are parameters of computer programs such as the name of the font used in the Button (computing), buttons, the background color of Menu (computing), menus, etc. They are used in conjunction with or as an alternative to command line parameters and configuration files. Format At the X protocol level, resources are strings that are stored in the server and have no special meaning. The syntax and meaning of these strings is given by client libraries and applications. Every X resource specifies a parameter for a program or one of its components. A fully specified resource has the following format: :application.component.subcomponent.subcomponent.attribute: value This resource specifies the value of attribute for the component named component.subcomponent.subcomponent of the program application. Resources are often used for specifying the parameters of GUI widget, widgets created by the application. Since these widgets are arranged in a tree (c ...

X Window System
The X Window System (X11, or simply 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. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a networked computer terminal, terminal has the ability to interact with the display with any type of user input device. In its standard distribution it is a complete, albeit simple, display and interface solution which delivers a standard widget toolkit, toolkit and protocol stack for building graphical user interfaces on most Unix-like operating syst ...

X Window Core Protocol
The X Window System core protocolRobert W. Scheifler and James Gettys: ''X Window System: Core and extension protocols, X version 11, releases 6 and 6.1'', Digital Press 1996, RFC 1013Grant EdwardsAn Introduction to X11 User Interfaces is the base protocol of the X Window System, which is a networked windowing system for bitmap displays used to build graphical user interfaces on Unix, Unix-like, and other operating systems. The X Window System is based on a client–server model: a single server controls the input/output hardware, such as the screen, the keyboard, and the mouse; all application programs act as clients, interacting with the user and with the other clients via the server. This interaction is regulated by the X Window System core protocol. Other protocols related to the X Window System exist, both built at the top of the X Window System core protocol or as separate protocols. In the X Window System core protocol, only four kinds of packets are sent, asynchronously, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convenience Function
A convenience function is a non-essential subroutine in a programming library or framework which is intended to ease commonly performed tasks. These convenience functions may be added arbitrarily based on the creator's perception of what these menial tasks will be, or they may be the result of a process of refactoring by the developers and community feedback on what could be made into a convenience function. A convenience function's task may almost always be expressed in terms of other operations, though this will likely have increased verbiage and reduced abstraction and possibly maintainability. From this perspective, any programming language above assembly language is a 'convenience language' to avoid writing machine code In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers, machine code is the binaryOn nonb .... Referen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Directory
A home directory is a directory (file systems), file system directory on a multi-user operating system containing computer file, files for a given user (computing), user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD (Filesystem Hierarchy Standard, FHS) systems use /home/ or /usr/home/, macOS uses /Users/, and Microsoft Windows, Windows systems since Windows Vista use \Users\. Description A user's home directory is intended to contain that user's files; including text documents, music, pictures, videos, etc. It may also include their configuration files of preferred settings for any software they have used there and might have tailored to their liking: web browser bookmark (digital), bookmarks, favorite desktop metaphor, desktop wallpaper (computing), wallpaper and theme (computing), themes, stored passwords to any external services accessed via a given software, etc. The use ...

Xrdb
xrdb (X resource database manager) is a program used for accessing the X resources of a server. Its main use is to read a set of resources from a file and store them in the server at startup. This program can access the resources in both read and write mode. In particular, it can read the resources stored in the server and can store a set of resources on the server, replacing or adding to the previous ones. It can operate either on the general display resources or on the ones specific to a screen. The main use of xrdb is however to load the resources when the X display server is started. For example, the instruction xrdb -load $HOME/.Xresources can be placed in scripts that are executed when the server is started to read the user preferences from the file .Xresources in his home directory. The original version of xrdb was written by Jim Gettys and later rewritten by Bob Scheifler and Phil Karlton. See also * X resources * X Window System The X Window System (X11, or sim ...

Database
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database. Before digital storage and retrieval of data have become widespread, index cards were used for data storage in a wide range of applications and environments: in the home to record and store recipes, shopping lists, contact information and other organizational data; in business to record presentation notes, project research and notes, and contact information; in schools as flash c ...

Xlib
Xlib (also known as libX11) is an X Window System protocol client library (computer science), library written in the C (programming language), C programming language. It contains subroutine, functions for interacting with an X Server (computing), server. These functions allow programmers to write programs without knowing the details of the X Window System protocols and architecture, X protocol. Few applications use Xlib directly; rather, they employ other libraries that use Xlib functions to provide widget toolkits: * X Toolkit Intrinsics (Xt) * X Athena Widgets, Athena widget set (Xaw) * Motif (software), Motif * FLTK * GTK * Qt (software), Qt (X11 version) * Tk (software), Tk * Simple DirectMedia Layer, SDL (Simple DirectMedia Layer) * Simple and Fast Multimedia Library, SFML (Simple and Fast Multimedia Library) Xlib, which was first publicly released in September 1985, is used in GUIs for many Unix-like operating systems. A re-implementation of Xlib was introduced in 2007 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterisk
The asterisk ( ), from Late Latin , from Ancient Greek , , "little star", is a Typography, typographical symbol. It is so called because it resembles a conventional image of a star (heraldry), heraldic star. Computer scientists and Mathematician, mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). An asterisk is usually five- or six-pointed in printing, print and six- or eight-pointed when handwritten, though more complex forms exist. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointer (computer programming), pointers, repetition, or multiplication. History The asterisk was already in use as a symbol in ice age Cave painting, cave paintings. There is also a two-thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeri ...
