Panel (computer Software)
A panel is "a particular arrangement of information grouped together for presentation to users in a window or pop-up". In ISPF, a panel is "a predefined display image that you see on a display screen". In modern multiple-document interface software a panel refers to a particular arrangement of information grouped together and presented to users ''docked'' (''by default)'' in the user interface rather than floating in a window, pop-up or dialog box. A panel graphical control element is commonly packaged as part of a widget toolkit (libraries that contain a collection of graphical control elements) for a graphical user interface. See toolbar and dialog box.

ISPF
In computing, Interactive System Productivity Facility (ISPF) is a software product for many historic IBM mainframe operating systems and currently the z/OS and z/VM operating systems that run on IBM mainframes. It includes a screen editor, the user interface of which was emulated by some microcomputer editors sold commercially starting in the late 1980s, including SPF/PC. ISPF primarily provides an IBM 3270 terminal interface with a set of panels. Each panel may include menus and dialogs to run tools on the underlying environment, e.g., Time Sharing Option (TSO). Generally, these panels just provide a convenient interface to do tasks—most of them execute modules of IBM mainframe utility programs to do the actual work. ISPF is frequently used to manipulate z/OS data sets via its Program Development Facility (ISPF/PDF). ISPF is user-extensible and it is often used as an application programming interface. Many vendors have created products for z/OS that use the ISPF interfac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple-document Interface
A multiple-document interface (MDI) is a graphical user interface in which multiple windows reside under a single parent window. Such systems often allow child windows to embed other windows inside them as well, creating complex nested hierarchies. This contrasts with single-document interfaces (SDI) where all windows are independent of each other. Comparison with single-document interface In the usability community, there has been much debate about whether the multiple-document or single-document interface is preferable. Software companies have used both interfaces with mixed responses. For example, Microsoft changed its Office applications from SDI to MDI mode and then back to SDI, although the degree of implementation varies from one component to another. SDI can be more useful in cases where users switch more often between separate applications than among the windows of one application. MDI can be confusing if it has a lack of information about the currently opened windows. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dialog Box
The dialog box (also called dialogue box (non-U.S. English), message box or simply dialog) is a graphical control element in the form of a small window that communicates information to the user and prompts them for a response. Dialog boxes are classified as " modal" or "modeless", depending on whether they block interaction with the software that initiated the dialog. The type of dialog box displayed is dependent upon the desired user interaction. The simplest type of dialog box is the alert, which displays a message and may require an acknowledgment that the message has been read, usually by clicking "OK", or a decision as to whether or not an action should proceed, by clicking "OK" or "Cancel". Alerts are also used to display a "termination notice"—sometimes requesting confirmation that the notice has been read—in the event of either an intentional closing or unintentional closing ("crash") of an application or the operating system. (E.g., "Gedit has encountered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphical Control Element
A graphical widget (also graphical control element or control) in a graphical user interface is an element of interaction, such as a button or a scroll bar. Controls are software components that a computer user interacts with through direct manipulation to read or edit information about an application. User interface libraries such as Windows Presentation Foundation, Qt, GTK, and Cocoa, contain a collection of controls and the logic to render these. Each widget facilitates a specific type of user-computer interaction, and appears as a visible part of the application's GUI as defined by the theme and rendered by the rendering engine. The theme makes all widgets adhere to a unified aesthetic design and creates a sense of overall cohesion. Some widgets support interaction with the user, for example labels, buttons, and check boxes. Others act as containers that group the widgets added to them, for example windows, panels, and tabs. Structuring a user interface with widget to ...

Widget Toolkit
A widget toolkit, widget library, GUI toolkit, or UX library is a library or a collection of libraries containing a set of graphical control elements (called ''widgets'') used to construct the graphical user interface (GUI) of programs. Most widget toolkits additionally include their own rendering engine. This engine can be specific to a certain operating system or windowing system or contain back-ends to interface with more multiple ones and also with rendering APIs such as OpenGL, OpenVG, or EGL. The look and feel of the graphical control elements can be hard-coded or decoupled, allowing the graphical control elements to be themed/ skinned. Overview Some toolkits may be used from other languages by employing language bindings. Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup language such as in this case GtkBuilder. The GUI of a program is commonly constructed in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

Toolbar
The toolbar, also called a bar or standard toolbar (originally known as ribbon) is a graphical control element on which on-screen icons can be used. A toolbar often allows for quick access to functions that are commonly used in the program. Some examples of functions a toolbar might have are open file, save, and change font. Toolbars are usually distinguished from palettes by their integration into the edges of the screen or of other windows. This can result in wasted space if multiple underpopulated bars are stacked atop each other or interface inefficiency if overloaded bars are placed on small windows. Variants There are several user interface elements derived from toolbars: * An address bar, location bar or URL bar is a toolbar that mainly consists of a text box. It typically accepts URLs or file system addresses. They are found in web browsers and file managers. * A breadcrumb or breadcrumb trail allows users to keep track of their locations within a program or a file sys ...

GNOME Panel
GNOME Panel is a highly configurable taskbar for GNOME. It formed a core part of the desktop in GNOME 1 and GNOME 2. It has been replaced in GNOME 3 by default with GNOME Shell, which only works with the Mutter window manager. There are many ''applets'' for GNOME Panel available in one package called ''gnome-applets'' while some applets included with GNOME Panel as built-in, like a traditional start menu. GNOME Panel served as ''Fallback Mode'' until GNOME 3.8 when Mutter could not be executed, then it was replaced with a suite of officially supported GNOME Shell extensions named ''GNOME Classic''. Now it is part of GNOME Flashback, an official session for GNOME 3 which provides a user experience similar to GNOME 2. In GNOME 3, customizing GNOME Panel is done by pressing the key while right-clicking on the panel. Appearance By default, GNOME Flashback contains two panels (one on the top, and one to its opposite on the bottom) spanning the width of the screen. The top panel ...

Kicker (KDE)
Kicker (also referred to as ''KDE Panel'') is the main panel used in KDE 3 and earlier, and also in the TDE desktop. Together with KDesktop, it forms the graphical shell. It can be customized by the user. By default, it has the K Menu, a Desktop Access button, a Home button, a Konqueror button, a Kontact button, and a Help button. It also has the Desktop Preview & Pager, the Taskbar, the System Tray, and the Clock. It was a core part of the KDE desktop, and as such, packaged as part of the kdebase module. Kicker was also ported from Qt3 to Qt4. In KDE Software Compilation 4, Kicker, KDesktop, and SuperKaramba were replaced by KDE Plasma 4. The s KDE Plasma 4 and |
Layout Manager
Layout managers are software components used in widget toolkits which have the ability to lay out graphical control elements by their relative positions without using distance units. It is often more natural to define component layouts in this manner than to define their position in pixels or common distance units, so a number of popular widget toolkits include this ability by default. Widget toolkits that provide this function can generally be classified into two groups: *Those where the layout behavior is coded in special graphic containers. This is the case in XUL and the .NET Framework widget toolkit (both in Windows Forms and in XAML). *Those where the layout behavior is coded in layout managers, that can be applied to any graphic container. This is the case in the Swing widget toolkit that is part of the Java API. Examples XUL In XUL XUL ( ), which stands for XML User Interface Language, is a user interface markup language developed by Mozilla. XUL is an XML dialect fo ...

Control Panel (computer)
Many computer user interfaces use a control panel metaphor to give the user control of software and hardware features. The control panel consists of multiple settings including display settings, network settings, user account settings, and hardware settings. Some control panels require the user to have admin rights or root access. Computer history The term control panel was used for the plugboards in unit record equipment and in the early computers of the 1940s and '50s. In the 1980s, the Xerox Star and the Apple Lisa, which pioneered the first graphical user interface metaphors, controlled user settings by single click selections and variable fields. In 1984 the Apple Macintosh in its initial release made use of fundamental graphic representation of a "control panel board" imitating the operation of slider controls, on/off buttons and radio-select buttons that corresponded to user settings. Functionality There are many tasks grouped in a control panel: Hardware * Color ** ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
