- Class Summary
  Class | Description
  --- | ---
  AncestorEvent | An event reported to a child component that originated from an ancestor in the component hierarchy.
  CaretEvent | CaretEvent is used to notify interested parties that the text caret has changed in the event source.
  ChangeEvent | ChangeEvent is used to notify interested parties that state has changed in the event source.
  DocumentEvent.EventType | Enumeration for document event types
  EventListenerList | A class that holds a list of EventListeners.
  HyperlinkEvent | HyperlinkEvent is used to notify interested parties that something has happened with respect to a hypertext link.
  HyperlinkEvent.EventType | Defines the ENTERED, EXITED, and ACTIVATED event types, along with their string representations, returned by toString().
  InternalFrameAdapter | An abstract adapter class for receiving internal frame events.
  InternalFrameEvent | An `AWTEvent` that adds support for `JInternalFrame` objects as the event source.
  ListDataEvent | Defines an event that encapsulates changes to a list.
  ListSelectionEvent | An event that characterizes a change in selection.
  MenuDragMouseEvent | MenuDragMouseEvent is used to notify interested parties that the menu element has received a MouseEvent forwarded to it under drag conditions.
  MenuEvent | MenuEvent is used to notify interested parties that the menu which is the event source has been posted, selected, or canceled.
  MenuKeyEvent | MenuKeyEvent is used to notify interested parties that the menu element has received a KeyEvent forwarded to it in a menu tree.
  MouseInputAdapter | An empty implementation of the `MouseInputListener` interface, provided as a convenience to simplify the task of creating listeners, by extending and implementing only the methods of interest.
  PopupMenuEvent | PopupMenuEvent only contains the source of the event which is the JPoupMenu sending the event
  RowSorterEvent | `RowSorterEvent` provides notification of changes to a `RowSorter`.
  SwingPropertyChangeSupport | This subclass of `java.beans.PropertyChangeSupport` is almost identical in functionality.

  TableModelEvent | TableModelEvent is used to notify listeners that a table model has changed.
  TreeExpansionEvent | An event used to identify a single path in a tree.
  TreeModelEvent | Encapsulates information describing changes to a tree model, and used to notify tree model listeners of the change.
  TreeSelectionEvent | An event that characterizes a change in the current selection.
  UndoableEditEvent | An event indicating that an operation which can be undone has occurred.
