Answers
Answer:
In computing, the term button (sometimes known as a command button or push 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.
Explanation:
Overview
A typical button is a rectangle or rounded rectangle, wider than it is tall, with a descriptive caption in its center.[2] The most common method of pressing a button is clicking it with a pointer controlled by a mouse, but other input such as keystrokes can be used to execute the command of a button. A button is not however always restricted to a rectangular shape. The sole requirement of button interaction is that the user can execute a command by a click action. Thus pictures and background areas can be programmed as buttons. When pressed, in addition to performing a predetermined task, buttons often undergo a graphical change to mimic a mechanical button being depressed.
A button often displays a tooltip when a user moves the pointer over it. The tooltip serves as built-in documentation that briefly explains the purpose of the button.
Some very common incarnations of the button widget are:
- An OK button for confirming actions and closing the windows
- A Cancel button for canceling actions and closing the window
- An Apply button for confirming actions without closing the window
- A Close button for closing windows after changes have already been applied
