Package java.awt.event

Provides interfaces and classes for dealing with different types of events fired by AWT components. See the java.awt.AWTEvent class for details on the AWT event model. Events are fired by event sources. An event listener registers with an event source to receive notifications about the events of a particular type. This package defines events and event listeners, as well as event listener adapters, which are convenience classes to make easier the process of writing event listeners.

The listener interface for receiving notification of events dispatched to objects that are instances of Component or MenuComponent or their subclasses.

The listener interface for receiving «interesting» mouse events (press, release, click, enter, and exit) on a component.

The listener interface for receiving WindowEvents , including WINDOW_GAINED_FOCUS and WINDOW_LOST_FOCUS events.

A class which extends the EventListenerProxy specifically for adding an AWTEventListener for a specific event mask.

A low-level event which indicates that a component moved, changed size, or changed visibility (also, the root class for the other component-level events).

A low-level event which indicates that a container’s contents changed because a component was added or removed.

An event which executes the run() method on a Runnable when dispatched by the AWT event dispatcher thread.

Awt event class in java

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 Summary

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.

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.

Method Detail

setSource

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.

getID

toString

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 boolean isConsumed()
