A pointing device is an input interface that allows a user to input spatial data to a computer. CAD systems and graphical user interfaces (GUI) allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer and other visual changes. Common gestures are point and click and drag and drop.
GNUstep is a free software implementation of the Cocoa Objective-C frameworks, widget toolkit, and application development tools for Unix-like operating systems and Microsoft Windows. It is part of the GNU Project.
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 used to construct the graphical user interface (GUI) of programs.
In computer interface design, a toolbar is a graphical control element on which on-screen buttons, icons, menus, or other input or output elements are placed. Toolbars are seen in many types of software such as office suites, graphics editors and web browsers. Toolbars are usually distinguished from palettes by their integration into the edges of the screen or larger windows, which results in wasted space if too many underpopulated bars are stacked atop each other or interface inefficiency if overloaded bars are placed on small windows.
A control element 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, GTK+, and Cocoa, contain a collection of controls and the logic to render these.
In computing, the term button refers to any graphical control element that provides the user a simple way to trigger an event, like searching for a query at a search engine, or to interact with dialog boxes, like confirming an action.
X Toolkit Intrinsics is a library that implements an API to facilitate the development of programs with a graphical user interface (GUI) for the X Window System. It can be used in the C or C++ languages.
In computing, a mouseover, mouse hover or hover box is a graphical control element that is activated when the user moves or hovers the pointer over a trigger area, usually with a mouse, but also possible with a digital pen. Mouseover control elements are common in web browsers. For example, hovering over a hyperlink triggers the mouseover control element to display a URL pn the status bar. Site designers can define their own mouseover events using JavaScript or Cascading Style Sheets.
A drop-down list is a graphical control element, similar to a list box, that allows the user to choose one value from a list. When a drop-down list is inactive, it displays a single value. When activated, it displays a list of values, from which the user may select one. When the user selects a new value, the control reverts to its inactive state, displaying the selected value. It is often used in the design of graphical user interfaces, including web design.
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".
An infobar is a graphical control element used e.g. by the Internet Explorer, Firefox, Google Chrome and other programs to display non-critical information to a user. It usually appears as a temporary extension of an existing toolbar, and may contain buttons or icons to allow the user to react to the event described in the infobar.
Control-C is a common computer command. It is generated by pressing the C key while holding down the Ctrl key on most computer keyboards.
The graphical control element inspector window is a type of dialog window that shows a list of the current attributes of a selected object and allows these parameters to be changed on the fly. A common use is in Integrated Development Environments, where the window shows the changing values of variables associated to an object during a debugging session.
A label is a graphical control element which displays text on a form. It is usually a static control; having no interactivity. A label is generally used to identify a nearby text box or other widget. Some labels can respond to events such as mouse clicks, allowing the text of the label to be copied, but this is not standard user-interface practice. Labels usually cannot be given the focus.
Words or sentences can be Greyed out in digital or printed texts to indicate less importance, relevance or priority or a change of status such as something being disabled or inaccessible.
A slider or track bar is a graphical control element with which a user may set a value by moving an indicator, usually in a horizontal fashion. In some cases user may also click on a point on the slider to change the setting. It is different from a scrollbar in that it is not continuous but used to adjust a value without changing the format of the display or the other information on the screen.
A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms.
A cycle button or toggle button is a graphical control element that allows the user to choose one from a predefined set of options. It is used as a button the content of which changes with each click and cycles between two or more values; the currently displayed value is the user's choice.
In computing, a pointer or mouse cursor is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place. It can be used in text-based or graphical user interfaces to select and move other elements. It is distinct from the cursor, which responds to keyboard input. The cursor may also be repositioned using the pointer.
