Re-parenting Window Manager
A re-parenting window manager is an X Window System window manager that adopts all other windows. In the X Window System, every window has a parent window, which may be either the root window or another window. Windows that are children of the root window are called ''top-level windows''. When a top-level window is created, a re-parenting window manager changes that window's parent to be a second new window created by the window manager for this purpose. This allows the window manager to decorate the windows with window decorations and title bars as well as allows advanced control over the windows' operation required, for example, by virtual window managers. Technically, a reparenting window manager registers with the X server to be notified when a top-level window is mapped (attempts to become visible). When such an event is generated, the window manager creates a frame window, and in most cases also a title bar window. The frame window then becomes the parent of both the mai ...

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 ...

Window Manager
A window manager is system software that controls the placement and appearance of window (computing), windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment. They work in conjunction with the underlying graphical system that provides required functionality—support for graphics hardware, pointing devices, and a keyboard—and are often written and created using a widget toolkit. Few window managers are designed with a clear distinction between the windowing system and the window manager. Every graphical user interface based on a windows metaphor has some form of window management. In practice, the elements of this functionality vary greatly. Elements usually associated with window managers allow the user to open, close, minimize, maximize, move, resize, and keep track of running windows, including window decorators. Many window managers also come with various utilities and features such as task b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Root Window
In the X Window System, a window is the region of the screen where drawing can occur. The root window covers the entire screen surface. Every window created is contained within it, forming a hierarchy with the root window at the very top. All other windows are either children or descendants of it. Since every window covers the part of its parent it is staying on, all other windows appear to be above the root window. As a result, the root window is visible as the part of the screen that is behind all other windows. In other words, the root window forms the background of the screen. An image can be used as the wallpaper of the screen by setting it as the background image of the root window. This can be done for example using the xsetroot or the xv programs. The direct children of the root window are called ''top-level windows''. These windows are usually drawn with a decorative frame and a title bar (which are actually added by the window manager). The top-level windows are, inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window Decoration
In computing, a window is a graphical control element. It consists of a visual area containing some of the graphical user interface of the program it belongs to and is framed by a window decoration. It usually has a rectangular shape that can overlap with the area of other windows. It displays the ''output'' of and may allow ''input'' to one or more processes. Windows are primarily associated with graphical displays, where they can be manipulated with a pointer by employing some kind of pointing device. Text-only displays can also support windowing, as a way to maintain multiple independent display areas, such as multiple buffers in Emacs. Text windows are usually controlled by keyboard, though some also respond to the mouse. A graphical user interface (GUI) using windows as one of its main "metaphors" is called a windowing system, whose main components are the display server and the window manager. History The idea was developed at the Stanford Research Institute (led by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Event-driven Programming
In computer programming, event-driven programming is a programming paradigm in which the Control flow, flow of the program is determined by external Event (computing), events. User interface, UI events from computer mouse, mice, computer keyboard, keyboards, touchpads and touchscreens, and external sensor inputs are common cases. Events may also be programmatically generated, such as from message passing, messages from other programs, notifications from other thread (computer science), threads, or other Computer network, network events. Event-driven programming is the dominant paradigm used in graphical user interfaces applications and network servers. In an event-driven application, there is generally an event loop that listens for events and then triggers a callback (computer programming), callback function when one of those events is detected. Event-driven programs can be written in any programming language, although the task is easier in languages that provide abstraction (co ...

Ultrix Window Manager
The Ultrix Window Manager (uwm) is a historic standard window manager software for the X Window System from X11R1 through X11R3 releases. In fact, it was the only X11-compatible window manager as of X11R1. History The Ultrix Window Manager was developed by the Digital Equipment Corporation for its Ultrix operating system. It was released in 1985. Shortly thereafter, it became included as part of the base X Window System distribution, beginning with X10R3. Initially, it was distributed alongside two other window managers ( xwm and xnwm). In 1986, the X Window System switched to version 11 of the protocol. Only uwm was ported, so it became the only window manager for X Window System until X11R4 release, where it was replaced by twm. Uwm has never been maintained since, although it has been patched for use in modern UNIX-like operating systems through the pkgsrc package manager. Description Unlike more recent window managers, uwm is not re-parenting, and does not place fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cwm (window Manager)
cwm (Calm Window Manager) is a stacking window manager for the X Window System. While it is primarily developed as a part of OpenBSD's base system, portable versions are available on other Unix-like operating systems. History Development of cwm started from patches to evilwm by Marius Aamodt Eriksen. To ease the implementation of new features, cwm was eventually rewritten using some code from 9wm. The last release by the original author came out in August 2005. In April 2007, cwm was imported into the OpenBSD source tree. By January 2008, a substantial part of the original source code, including all of the 9wm code, was rewritten. cwm has been distributed with OpenBSD since version 4.2, where it replaced wm2. A third-party Linux port also exists. Description cwm is a stacking window manager oriented towards heavy keyboard usage, small footprint and ease of use. While it lacks explicit virtual desktops functionality, it can be emulated by using the window groups mechanis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratpoison
ratpoison is a tiling window manager for the X Window System primarily developed by Shawn Betts. The user interface and much of their functionality are inspired by the GNU Screen terminal multiplexer. While ratpoison is written in C, Betts' StumpWM re-implements a similar window manager in Common Lisp. Overview The name "ratpoison" reflects its major design goal: to let the user manage application windows without using a mouse. Unlike other tiling window managers like Ion, ratpoison completely ignores the mouse (or "rat"), and avoids window decorations as much as possible. The default keybindings are specifically designed to not conflict with Emacs. Usage ratpoison relies on key chords similar to Emacs to control window management, with all window interactions being done through shortcuts. Each window occupies an entire frame and cannot overlap. Windows can be split either horizontally or vertically. Multiple workspaces and session management are supported. An applica ...
