class:AWTEvent [NONE]
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
ActionEvent, AdjustmentEvent, AncestorEvent, ComponentEvent, HierarchyEvent, InputMethodEvent, InternalFrameEvent, InvocationEvent, ItemEvent, TextEvent
public abstract class AWTEventextends EventObject
The root event class for all AWT events. This class and its subclasses supersede 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.

field:id [NONE]

  • id

    protected int id
    The event's id.
    See Also:

    • field:consumed [NONE]

    consumed

    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.

  • AWTEvent

    @Deprecated(since="9") public AWTEvent (Event event)
    Deprecated.
    It is recommended that AWTEvent(Object, int) be used instead
    Constructs an AWTEvent object from the parameters of a 1.0-style event.

    id - the event type

    method:setSource(java.lang.Object) [NONE]

  • setSource

    public 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.

    Parameters:
    newSource - the new Object to which the event should be dispatched
