From Wikipedia, the free encyclopedia

Example of a dialog box of gedit.
In graphical user interfaces, a dialog (or dialogue) box is a special window, used in user interfaces to display information to the user, or to get a response if needed. They are so-called because they form a dialog between the computer and the user—either informing the user of something, or requesting input from the user, or both. It provides controls that allow you to specify how to carry out an action.
Dialog boxes are classified as modal or modeless, depending on whether they block interaction on the application that triggered the dialog. Different types of dialog boxes are used for different sorts of user interaction.
The simplest type of dialog box is the alert, which displays a message and requires only an acknowledgment (by clicking 'OK' usually) that the message has been read. Alerts are used to provide simple confirmation of an action, or include program termination notices or confirmation due to crashing or intentional closing by user. Though this is a frequent interaction pattern for modal dialogs, it is also criticised by usability experts as being ineffective for its intended use (protection against errors in destructive actions)[1] and for which better alternatives exist.[2]
