Virtual Desktops
In computing, a virtual desktop is a term used with respect to user interfaces, usually within the WIMP paradigm, to describe ways in which the virtual space of a computer's desktop environment is expanded beyond the physical limits of the screen's display area through the use of software. This compensates limits of the desktop area and is helpful in reducing clutter of running graphical applications. There are two major approaches to expanding the virtual area of the screen. Switchable virtual desktops allow the user to make virtual copies of their desktop view-port and switch between them, with open windows existing on single virtual desktops. Another approach is to expand the size of a single virtual screen beyond the size of the physical viewing device. Typically, scrolling/panning a subsection of the virtual desktop into view is used to navigate an oversized virtual desktop. Overview Switching desktops Switchable desktops were designed and implemented at Xerox PAR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viewport
A viewport is a polygon viewing region in computer graphics. In computer graphics theory, there are two region-like notions of relevance when rendering some objects to an image. In textbook terminology, the '' world coordinate window'' is the area of interest (meaning what the user wants to visualize) in some application-specific coordinates, e.g. miles, centimeters etc. The word ''window'' as used here should not be confused with the GUI window, i.e. the notion used in window managers. Rather it is an analogy with how a window limits what one can see outside a room. In contrast, the ''viewport'' is an area (typically rectangular) expressed in rendering-device-specific coordinates, e.g. pixels for screen coordinates, in which the objects of interest are going to be rendered. Clipping to the world-coordinates window is usually applied to the objects before they are passed through the window-to-viewport transformation. For a 2D object, the latter transformation is simply a combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sawfish (window Manager)
Sawfish is a window manager for the X Window System. It aims to manage windows in the most flexible and attractive manner possible. It is able to match a window by multiple criteria such as application, size or role, and based on this, can change the window's position, appearance, or behavior. This allows for highly customized window handling such as web browser windows opening full-screen without borders on a secondary monitor, a default terminal emulator window displaying full-screen at the desktop level, and all dialog box windows under a certain size opening on the lower right corner of the main monitor while larger ones are centered. Sawfish uses a Lisp-like scripting language, rep, for all of its code and configuration, making it particularly easy to customize, or program many kinds of behavior, responding to window creation, deletion, or any other changes. There is a GUI configuration utility for users who do not wish to edit configuration files directly. History Sawfi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
