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.

public static final ACTION_EVENT_MASK

The event mask for selecting action events.

public static final ADJUSTMENT_EVENT_MASK

The event mask for selecting adjustment events.

public static final COMPONENT_EVENT_MASK

The event mask for selecting component events.

protected 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 CONTAINER_EVENT_MASK

The event mask for selecting container events.

public static final FOCUS_EVENT_MASK

The event mask for selecting focus events.

public static final HIERARCHY_BOUNDS_EVENT_MASK

The event mask for selecting hierarchy bounds events.

public static final HIERARCHY_EVENT_MASK

The event mask for selecting hierarchy events.

protected id

The event's id.

public static final INPUT_METHOD_EVENT_MASK

The event mask for selecting input method events.

public static final INVOCATION_EVENT_MASK

The event mask for selecting invocation events.

public static final ITEM_EVENT_MASK

The event mask for selecting item events.

public static final KEY_EVENT_MASK

The event mask for selecting key events.

public static final MOUSE_EVENT_MASK

The event mask for selecting mouse events.

public static final MOUSE_MOTION_EVENT_MASK

The event mask for selecting mouse motion events.

public static final MOUSE_WHEEL_EVENT_MASK

The event mask for selecting mouse wheel events.

public static final PAINT_EVENT_MASK

The event mask for selecting paint events.

public static final 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 static final TEXT_EVENT_MASK

The event mask for selecting text events.

public static final WINDOW_EVENT_MASK

The event mask for selecting window events.

public static final WINDOW_FOCUS_EVENT_MASK

The event mask for selecting window focus events.

public static final WINDOW_STATE_EVENT_MASK

The event mask for selecting window state events.

public AWTEvent(Event)

Constructs an AWTEvent object from the parameters of a 1.0-style event.

Parameters

Event event: the old-style event

public AWTEvent(Object, int)

Constructs an AWTEvent object with the specified source object and type.

Parameters

Object source: the object where the event originated

int id: the event type

protected void consume()

Consumes this event, if this event can be consumed. Only low-level, system events can be consumed

public int getID()

Returns the event type.

protected boolean isConsumed()

Returns whether this event has been consumed.

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.

public void setSource(Object)

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

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