Interface elements known as graphical control elements, controls or widgets 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 user-computer interaction.
A graphical user interface, or GUI [a], is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs , which are based on typed command labels or text navigation.
User interface libraries such as Windows Presentation Foundation, Qt, GTK, and Cocoa, contain a collection of controls and the logic to render these.

Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup language such as in this case GtkBuilder. The GUI of a program is commonly constructed in a cascading manner, with graphical control elements being added directly to on top of one another.
The view component of a Swing JComponent is the object used to graphically represent the conceptual GUI control. A distinction of Swing, as a GUI framework, is in its reliance on programmatically rendered GUI controls (as opposed to the use of the native host OS's GUI controls).
An integration tree (or GUI tree) is a graph that visualises all the GUI components of a software. Each node of the tree show the GUI components used in this software. The components on the leaves of the tree are modeless GUI elements, those on the nodes are modal GUI elements. GUIs are highly involved entities.
