+/**
+ * A semantic event which indicates that an item was selected or deselected.
+ * This high-level event is generated by an ItemSelectable object (such as a
+ * List) when an item is selected or deselected by the user.
+ * The event is passed to every <code>ItemListener</code> object which
+ * registered to receive such events using the component's
+ * <code>addItemListener</code> method.
+ * <P>
+ * The object that implements the <code>ItemListener</code> interface gets
+ * this <code>ItemEvent</code> when the event occurs. The listener is
+ * spared the details of processing individual mouse movements and mouse
+ * clicks, and can instead process a "meaningful" (semantic) event like
+ * "item selected" or "item deselected".
+ * <p>
+ * An unspecified behavior will be caused if the {@code id} parameter
+ * of any particular {@code ItemEvent} instance is not
+ * in the range from {@code ITEM_FIRST} to {@code ITEM_LAST}.
+ * <p>
+ * The {@code stateChange} of any {@code ItemEvent} instance takes one of the following
+ * values:
+ *                     <ul>

+/**
+ * An event which indicates that the mouse wheel was rotated in a component.
+ * <P>
+ * A wheel mouse is a mouse which has a wheel in place of the middle button.
+ * This wheel can be rotated towards or away from the user.  Mouse wheels are
+ * most often used for scrolling, though other uses are possible.
+ * <P>
+ * A MouseWheelEvent object is passed to every <code>MouseWheelListener</code>
+ * object which registered to receive the "interesting" mouse events using the
+ * component's <code>addMouseWheelListener</code> method.  Each such listener
+ * object gets a <code>MouseEvent</code> containing the mouse event.
+ * <P>
+ * Due to the mouse wheel's special relationship to scrolling Components,
+ * MouseWheelEvents are delivered somewhat differently than other MouseEvents.
+ * This is because while other MouseEvents usually affect a change on
+ * the Component directly under the mouse
+ * cursor (for instance, when clicking a button), MouseWheelEvents often have
+ * an effect away from the mouse cursor (moving the wheel while
+ * over a Component inside a ScrollPane should scroll one of the
+ * Scrollbars on the ScrollPane).
+ * <P>
+ * MouseWheelEvents start delivery from the Component underneath the
+ * mouse cursor.  If MouseWheelEvents are not enabled on the
+ * Component, the event is delivered to the first ancestor
+ * Container with MouseWheelEvents enabled.  This will usually be
+ * a ScrollPane with wheel scrolling enabled.  The source
+ * Component and x,y coordinates will be relative to the event's
+ * final destination (the ScrollPane).  This allows a complex
+ * GUI to be installed without modification into a ScrollPane, and
+ * for all MouseWheelEvents to be delivered to the ScrollPane for
+ * scrolling.
+ * <P>
+ * Some AWT Components are implemented using native widgets which
+ * display their own scrollbars and handle their own scrolling.
+ * The particular Components for which this is true will vary from
+ * platform to platform.  When the mouse wheel is
+ * moved over one of these Components, the event is delivered straight to
+ * the native widget, and not propagated to ancestors.
+ * <P>
+ * Platforms offer customization of the amount of scrolling that
+ * should take place when the mouse wheel is moved.  The two most
+ * common settings are to scroll a certain number of "units"
+ * (commonly lines of text in a text-based component) or an entire "block"
+ * (similar to page-up/page-down).  The MouseWheelEvent offers
+ * methods for conforming to the underlying platform settings.  These
+ * platform settings can be changed at any time by the user.  MouseWheelEvents
+ * reflect the most recent settings.
+ * <P>
+ * The <code>MouseWheelEvent</code> class includes methods for
+ * getting the number of "clicks" by which the mouse wheel is rotated.
+ * The {@link #getWheelRotation} method returns the integer number
+ * of "clicks" corresponding to the number of notches by which the wheel was
+ * rotated. In addition to this method, the <code>MouseWheelEvent</code>
+ * class provides the {@link #getPreciseWheelRotation} method which returns
+ * a double number of "clicks" in case a partial rotation occurred.
+ * The {@link #getPreciseWheelRotation} method is useful if a mouse supports
+ * a high-resolution wheel, such as a freely rotating wheel with no
+ * notches. Applications can benefit by using this method to process
+ * mouse wheel events more precisely, and thus, making visual perception
+ * smoother.
