CommandButton

CommandButton is a common user interface element found in many graphical user interfaces. Its primary purpose is to initiate an action when clicked by the user. This action is typically defined by the application's programming.

Visually, a CommandButton is usually represented as a rectangular area with text or an icon displayed on it. The text commonly describes the action the button will perform, such as "Save," "Cancel," "Submit," or "OK." When a user clicks or taps the button, it often provides visual feedback, such as appearing depressed or changing color, to indicate that the input has been registered.

The functionality of a CommandButton is determined by the software it is part of. For instance, in a web form, a "Submit" button will send the entered data to a server. In a desktop application, a "Save" button will persist changes made to a document. CommandButtons are fundamental building blocks for user interaction, enabling users to control program flow and execute specific operations. They are a straightforward and intuitive way for users to interact with software.
