Class AWTEvent
- Serializable
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.
AWTEvent(Event event)- Initializes a new AWTEvent from the old Java 1.0 event object.
|
AWTEvent(Object source, int id)- Create an event on the specified source object and id.
|
protected void | consume()- Consumes this event so that it will not be processed in the default
manner.
|
int | getID()- Returns the event type id.
|
protected boolean | isConsumed()- Tests whether not not this event has been consumed.
|
String | paramString()- Returns a string representation of the state of this event.
|
void | setSource(Object source)- Retarget the event, such as converting a heavyweight component to a
lightweight child of the original.
|
String | toString()- Create a string that represents this event in the format
classname[eventstring] on sourcecomponentname.

COMPONENT_EVENT_MASK
public static final long COMPONENT_EVENT_MASK
Mask for selecting component events.
CONTAINER_EVENT_MASK
public static final long CONTAINER_EVENT_MASK
Mask for selecting container events.
FOCUS_EVENT_MASK
public static final long FOCUS_EVENT_MASK
Mask for selecting component focus events.
ITEM_EVENT_MASK
public static final long ITEM_EVENT_MASK
Mask for item events.
KEY_EVENT_MASK
public static final long KEY_EVENT_MASK
Mask for selecting keyboard events.
MOUSE_EVENT_MASK
public static final long MOUSE_EVENT_MASK
Mask for mouse button events.
PAINT_EVENT_MASK
public static final long PAINT_EVENT_MASK
Mask for paint events.
RESERVED_ID_MAX
public static final int RESERVED_ID_MAX
This is the highest number for event ids that are reserved for use by
the AWT system itself. Subclasses outside of java.awt should use higher
ids.
TEXT_EVENT_MASK
public static final long TEXT_EVENT_MASK
Mask for text events.
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.
id
protected int id
The ID of the event.
AWTEvent
public AWTEvent(Event event)
Initializes a new AWTEvent from the old Java 1.0 event object.
event - the old-style event
AWTEvent
public AWTEvent(Object source,
int id) Create an event on the specified source object and id.
source - the object that caused the eventid - the event id
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.
- 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.
- 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.
- a string representation of this event
setSource
public void setSource(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.
toString
public String toString()
Create a string that represents this event in the format
classname[eventstring] on sourcecomponentname.
- toString in interface EventObject
- a string representing this event
AWTEvent.java -- the root event in AWT
