public abstract class MouseAdapter extends Object implements MouseListener, MouseWheelListener, MouseMotionListener
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, when it exits and when a mouse wheel is moved.
Extend this class to create a
MouseEvent(including drag and motion events) or/andMouseWheelEventlistener and override the methods for the events of interest. (If you implement theMouseListener,MouseMotionListenerinterface, 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
addMouseListeneraddMouseMotionListener,addMouseWheelListenermethods. The relevant method in the listener object is invoked and theMouseEventorMouseWheelEventis 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

Method Detail
-
mouseClicked
public void mouseClicked(MouseEvent e)
Invoked when the mouse button has been clicked (pressed and released) on a component.- Specified by:
mouseClickedin interfaceMouseListener
-
mousePressed
public void mousePressed(MouseEvent e)
Invoked when a mouse button has been pressed on a component.- Specified by:
mousePressedin interfaceMouseListener
-
mouseReleased
public void mouseReleased(MouseEvent e)
Invoked when a mouse button has been released on a component.- Specified by:
mouseReleasedin interfaceMouseListener
-
mouseEntered
public void mouseEntered(MouseEvent e)
Invoked when the mouse enters a component.- Specified by:
mouseEnteredin interfaceMouseListener
-
mouseExited
public void mouseExited(MouseEvent e)
Invoked when the mouse exits a component.- Specified by:
mouseExitedin interfaceMouseListener
-
mouseWheelMoved
public void mouseWheelMoved(MouseWheelEvent e)
Invoked when the mouse wheel is rotated.- Specified by:
mouseWheelMovedin interfaceMouseWheelListener- Since:
- 1.6
- See Also:
MouseWheelEvent
-
mouseDragged
public void mouseDragged(MouseEvent e)
Invoked when a mouse button is pressed on a component and then dragged.MOUSE_DRAGGEDevents 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_DRAGGEDevents may not be delivered during a native Drag&Drop operation.- Specified by:
mouseDraggedin interfaceMouseMotionListener- Since:
- 1.6
-
mouseMoved
public void mouseMoved(MouseEvent e)
Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.- Specified by:
mouseMovedin interfaceMouseMotionListener- Since:
- 1.6
