"A graphical control element or widget is an element of interaction in a graphical user interface (GUI), 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. ...
Each widget facilitates a specific type of user-computer interaction, and appears as a visible part of the application's GUI as defined by the theme and rendered by the rendering engine. The theme makes all graphical control elements adhere to a unified aesthetic design and creates a sense of overall cohesion. Some widgets support interaction with the user, for example labels, buttons, and check boxes. Others act as containers that group the widgets added to them, for example windows, panels, and tabs."
