Class java.awt.AWTEvent

- Subclasses:
- ActionEvent, AdjustmentEvent, AncestorEvent, ComponentEvent, InputMethodEvent, InternalFrameEvent, ItemEvent, TextEvent
- public abstract class AWTEvent
- extends EventObject
The root event class for all AWT events.
This class and its subclasses supercede the original
java.awt.Event class.
Subclasses of this root AWTEvent class defined outside of the
java.awt.event package should define event ID values greater than
the value defined by RESERVED_ID_MAX.
The event masks defined in this class are needed ONLY by
component subclasses which are using Component.enableEvents()
to select for event types not selected by registered listeners.
If a listener is registered on a component, the appropriate event
mask is already set internally by the component.
