AWTEvent is the root event class for all AWT events in the JDK 1.1 event
model. It supersedes the Event class from JDK 1.0. Subclasses outside of
the java.awt package should have IDs greater than RESERVED_ID_MAX.
Event masks defined here are used by components in
enableEvents
to select event types not selected by registered
listeners. Event masks are appropriately set when registering on
components.

consumed
protected boolean consumed
Indicates if the event has been consumed. False mean it is passed to
the peer, true means it has already been processed. Semantic events
generated by low-level events always have the value true.
See Also:
id
protected int id
The ID of the event.

AWTEvent
public AWTEvent(java.awt.Event event)
Initializes a new AWTEvent from the old Java 1.0 event object.
Parameters:
Throws:
AWTEvent
public AWTEvent(java.lang.Object source, int id)
Create an event on the specified source object and id.
Parameters:
Throws:
consume
protected void consume()
Consumes this event so that it will not be processed in the default
manner.
getID
public int getID()
Returns the event type id.
Returns:
- the id number of this event
isConsumed
protected boolean isConsumed()
Tests whether not not this event has been consumed. A consumed event
is not processed in the default manner.
Returns:
- true if this event has been consumed
paramString
public String paramString()
Returns a string representation of the state of this event. It may be
empty, but must not be null; it is implementation defined.
Returns:
- a string representation of this event
setSource
public void setSource(java.lang.Object source)
Retarget the event, such as converting a heavyweight component to a
lightweight child of the original. This is not for general use, but
is for event targeting systems like KeyboardFocusManager.
Parameters:
toString
public String toString()
Returns a string representation of this event. This is in the format
getClass().getName() + '[' + paramString() + "] on "
+ source
.
Returns:
- a string representation of this event
