abstract class Component extends UIElement

Base class for all UI elements that can be displayed in a window. Components are publishers that fire the following event classes: ComponentEvent, FocusEvent, FontChanged, ForegroundChanged, BackgroundChanged.

Note

[Java Swing] Unlike in Java Swing, not all components are also containers.
