- Class Summary
  Class | Description
  --- | ---
  ActionEvent | A semantic event which indicates that a component-defined action occurred.
  AdjustmentEvent | The adjustment event emitted by Adjustable objects like `Scrollbar` and `ScrollPane`.
  AWTEventListenerProxy | A class which extends the `EventListenerProxy` specifically for adding an `AWTEventListener` for a specific event mask.
  ComponentAdapter | An abstract adapter class for receiving component events.
  ComponentEvent | 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).
  ContainerAdapter | An abstract adapter class for receiving container events.
  ContainerEvent | A low-level event which indicates that a container's contents changed because a component was added or removed.
  FocusAdapter | An abstract adapter class for receiving keyboard focus events.
  FocusEvent | A low-level event which indicates that a Component has gained or lost the input focus.
  HierarchyBoundsAdapter | An abstract adapter class for receiving ancestor moved and resized events.
  HierarchyEvent | An event which indicates a change to the `Component` hierarchy to which `Component` belongs.
  InputEvent | The root event class for all component-level input events.
  InputMethodEvent | Input method events contain information about text that is being composed using an input method.
  InvocationEvent | An event which executes the `run()` method on a `Runnable` when dispatched by the AWT event dispatcher thread.
  ItemEvent | A semantic event which indicates that an item was selected or deselected.
  KeyAdapter | An abstract adapter class for receiving keyboard events.
  KeyEvent | An event which indicates that a keystroke occurred in a component.
  MouseAdapter | An abstract adapter class for receiving mouse events.
  MouseEvent | An event which indicates that a mouse action occurred in a component.
  MouseMotionAdapter | An abstract adapter class for receiving mouse motion events.
  MouseWheelEvent | An event which indicates that the mouse wheel was rotated in a component.
  PaintEvent | The component-level paint event.
  TextEvent | A semantic event which indicates that an object's text changed.
  WindowAdapter | An abstract adapter class for receiving window events.
  WindowEvent | A low-level event that indicates that a window has changed its status.

## Package java.awt.event Description

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.
