public abstract class MouseAdapter
An abstract adapter class for receiving mouse events. The methods in this class are empty. This class exists as convenience for creating listener objects.
Mouse events let you track when a mouse is pressed, released, clicked,
moved, dragged,
when it enters a component,
and
when it
exits
exits. (To track mouse moves
and
when a
mouse
wheel is moved.
drags, use the MouseMotionAdapter.)
Extend this class to create a MouseEvent
(including drag and motion events) or/and MouseWheelEvent
listener and override the methods for the events of interest. (If you implement the
MouseListener, MouseMotionListener
MouseListener
interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)
Create a listener object using the extended class and then register it with a component using the component's addMouseListener
addMouseMotionListener, addMouseWheelListener methods. The
method. When a mouse button is pressed, released, or clicked (pressed and released), or when the mouse cursor enters or exits the component, the
relevant method in the listener object is invoked and the MouseEvent
or MouseWheelEvent
is passed to
it in following cases:
it.
