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 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.
The masks are also used to specify to which types of events an AWTEventListener should listen. The masks are bitwise-ORed together and passed to Toolkit.addAWTEventListener.
Component.enableEvents(long), Toolkit.addAWTEventListener(java.awt.event.AWTEventListener, long), ActionEvent, AdjustmentEvent, ComponentEvent, ContainerEvent, FocusEvent, InputMethodEvent, InvocationEvent, ItemEvent, HierarchyEvent, KeyEvent, MouseEvent, MouseWheelEvent, PaintEvent, TextEvent, WindowEvent, Serialized Formprotected int id
The event's id.
getID(), AWTEvent(java.lang.Object, int)
protected boolean consumed
Controls whether or not the event is sent back down to the peer once the source has processed it - false means it's sent to the peer; true means it's not. Semantic events always have a 'true' value since they were generated by the peer in response to a low-level event.

public static final long WINDOW_STATE_EVENT_MASK
The event mask for selecting window state events.
public static final long WINDOW_FOCUS_EVENT_MASK

public static final int RESERVED_ID_MAX
The maximum value for reserved AWT event IDs. Programs defining their own event IDs should use IDs greater than this value.
public AWTEvent(Event event)
Constructs an AWTEvent object from the parameters of a 1.0-style event.
event - the old-style eventpublic AWTEvent(Object source,
int id) Constructs an AWTEvent object with the specified source object and type.
source - the object where the event originatedid - the event typepublic void setSource(Object newSource)
Retargets an event to a new source. This method is typically used to retarget an event to a lightweight child Component of the original heavyweight source.
This method is intended to be used only by event targeting subsystems, such as client-defined KeyboardFocusManagers. It is not for general client use.
newSource - the new Object to which the event should be dispatchedpublic int getID()
Returns the event type.
public String toString()
Returns a String representation of this object.
toString in class EventObject
public String paramString()
Returns a string representing the state of this Event. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.
protected void consume()
Consumes this event, if this event can be consumed. Only low-level, system events can be consumed
protected boolean isConsumed()
Returns whether this event has been consumed.
