Mouse events let you track when a mouse is pressed, released, clicked, moved, dragged, when it enters a component, when it exits and when a mouse wheel is moved.
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
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 relevant method in the listener object is invoked and the MouseEvent
or MouseWheelEvent
is passed to it in following cases:
- when a mouse button is pressed, released, or clicked (pressed and released)
- when the mouse cursor enters or exits the component
- when the mouse wheel rotated, or mouse moved or dragged
- Since:
- 1.1

e
- the event to be processed
-
mousePressed
Invoked when a mouse button has been pressed on a component.- Specified by:
mousePressed
in interfaceMouseListener
- Parameters:
e
- the event to be processed
-
mouseReleased
Invoked when a mouse button has been released on a component.- Specified by:
mouseReleased
in interfaceMouseListener
- Parameters:
e
- the event to be processed
-
mouseEntered
Invoked when the mouse enters a component.- Specified by:
mouseEntered
in interfaceMouseListener

-
mouseExited
Invoked when the mouse exits a component.- Specified by:
mouseExited
in interfaceMouseListener

-
mouseDragged
Invoked when a mouse button is pressed on a component and then dragged.MOUSE_DRAGGED
events will continue to be delivered to the component where the drag originated until the mouse button is released (regardless of whether the mouse position is within the bounds of the component).Due to platform-dependent Drag&Drop implementations,
MOUSE_DRAGGED
events may not be delivered during a native Drag&Drop operation.- Specified by:
mouseDragged
in interfaceMouseMotionListener
- Parameters:
e
- the event to be processed- Since:
- 1.6
-
mouseMoved
Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.- Specified by:
mouseMoved
in interfaceMouseMotionListener
- Parameters:
e
