Focus Stealing
In computing, focus stealing is a mode error occurring when a program not in focus (e.g. minimized or operating in background) places a window in the foreground and redirects all keyboard input to that window. This is considered to be an annoyance or hazard to some users because the program may steal the focus while the user is typing, causing keystrokes to go to the newly focused window, possibly being lost or causing an unintended effect therein. This may be a few keystrokes due to reaction time, or may be more if the user's attention is not on the computer screen, e.g. typing while looking at the keyboard or while reading copy to the side, or if processor lag causes a delay (sometimes of several seconds) between the focus stealing event and the newly focused window displaying on the screen. Security issues Focus stealing can cause damage, as users may, while typing when their attention is away from the screen, inadvertently agree to a program doing something that causes damage. ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fvwm
The F Virtual Window Manager is a virtual window manager for the X Window System. Originally a twm derivative, FVWM has evolved into a powerful and highly configurable environment for Unix-like systems. History In 1993, during his work analyzing acoustic signatures for the United States Department of Defense, Robert Nation began hacking twm with the intent of simultaneously reducing memory usage and adding support for virtual desktops. Already known for his rxvt terminal emulator, Nation worked on reducing the memory consumption of his new window manager. Deciding to test FVWM's reception, on June 1, 1993, he bundled it with a rxvt release. In 1994 Rob Nation stopped developing FVWM and made Charles Hines the maintainer. Rob Nation's last release of FVWM was fvwm-1.24r. The post-Rob Nation version of FVWM uses a different configuration file format and has a significantly different architecture. Many Linux distributions, as a result, distributed both fvwm-1.24r and later relea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mode (user Interface)
In user interface design, a mode is a distinct setting within a computer program or any physical machine interface, in which the same user input will produce perceived results different from those that it would in other settings. Modal interface components include the Caps lock and Insert keys on the standard computer keyboard, both of which typically put the user's typing into a different mode after being pressed, then return it to the regular mode after being re-pressed. An interface that uses no modes is known as a ''modeless'' interface. Modeless interfaces avoid ''mode errors'', in which the user performs an action appropriate to one mode while in another mode, by making it impossible for the user to commit them. Definition In his book '' The Humane Interface'', Jef Raskin defines modality as follows: "An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface ...

Process Explorer
Process Explorer is a freeware task manager and system monitor for Microsoft Windows created by SysInternals, which has been acquired by Microsoft and re-branded as Windows Sysinternals. It provides the functionality of Windows Task Manager along with a rich set of features for collecting information about processes running on the user's system. It can be used as the first step in debugging software or system problems. Process Explorer can be used to track down problems. For example, it provides a means to list or search for named resources that are held by a process or all processes. This can be used to track down what is holding a file open and preventing its use by another program. As another example, it can show the command lines used to start a program, allowing otherwise identical processes to be distinguished. Like Task Manager, it can show a process that is maxing out the CPU, but unlike Task Manager it can show which thread (with the callstack) is using the CPU – informa ...

Mozilla Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. In November 2017, Firefox began incorporating new technology under the code name "Quantum" to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 and later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser. Firefox was created in 2002 under t ...

IceWM
IceWM is a stacking window manager for the X Window System, originally written by Marko Maček. It was written from scratch in C++ and is released under the terms of the GNU Lesser General Public License. It is customizable, relatively lightweight in terms of memory and CPU usage, and comes with themes that allow it to imitate the GUI of Windows 95, Windows XP, Windows 7, OS/2, Motif, and other graphical user interfaces. IceWM can be configured from plain text files stored in a user's home directory, making it easy to customize and copy settings. IceWM has an optional, built-in taskbar with a dynamic start menu, tasks display, system tray, network and CPU meters, mail check and configurable clock. It features a task list window and an Alt+Tab task switcher. Official support for GNOME and KDE menus used to be available as a separate package. In recent IceWM versions, support for them is built-in as well. External graphical programs for editing the configuration and the menu a ...

Compiz
Compiz () is a compositing window manager for the X Window System, using 3D graphics hardware to create fast compositing desktop effects for window management. Effects, such as a minimization animation or a cube workspace, are implemented as loadable plugins. Because it conforms to the ICCCM conventions, Compiz can be used as a substitute for the default Mutter or Metacity, when using GNOME Panel, or KWin in KDE Plasma Workspaces. Internally Compiz uses the OpenGL library as the interface to the graphics hardware. Hardware requirements Initially, Compiz only worked with 3D hardware supported by Xgl. Most NVIDIA and ATI graphics cards are known to work with Compiz on Xgl. Since May 22, 2006 Compiz works on the standard X.Org Server, by using AIGLX. Besides Intel GMA graphics cards, AIGLX also supports using AMD graphics cards (including R300 and newer cards) using the open-source driver which supports since fall 2006. NVIDIA's binary drivers (since Version 1.0-9629) support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window Manager
A window manager is system software that controls the placement and appearance of 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 bars, program launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
