Check Box

Definition

A check box is a square graphical control element in a dialog box or user interface that allows users to make a binary choice. It can be clicked with the mouse to turn an option on (checked) or off (unchecked). Check boxes are typically used for settings where multiple options can be selected simultaneously, unlike radio buttons, which are used for settings where only one option is selectable within a group.

Examples

  1. Font Formatting Dialog: A typical example is a font formatting dialog where a user can enable multiple formatting options such as italic, boldface, and superscript by ticking the corresponding check boxes.
  2. Preferences Settings: In software preference settings, users can enable or disable various features like auto-save, dark mode, or notifications by clicking the appropriate check boxes.

Frequently Asked Questions (FAQs)

What is the primary function of a check box?

A check box allows users to select or deselect one or multiple options independently of others in the user interface.
