# Class BasicListUI.MouseInputHandler

javax.swing.plaf.basic.BasicListUI.MouseInputHandler

All Implemented Interfaces:
  `MouseListener`, `MouseMotionListener`, `EventListener`, `MouseInputListener`

Enclosing class:
  `BasicListUI`

public class BasicListUI.MouseInputHandler extends Object implements MouseInputListener
Mouse input, and focus handling for JList. An instance of this class is added to the appropriate java.awt.Component lists at installUI() time. Note keyboard input is handled with JComponent KeyboardActions, see installKeyboardActions().

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.

- ## Method Details

  - ### mouseClicked

    public void mouseClicked(MouseEvent e)
    Description copied from interface: `MouseListener`
    Invoked when the mouse button has been clicked (pressed and released) on a component.
    Specified by:
      `mouseClicked` in interface `MouseListener`
    Parameters:
      `e` - the event to be processed

  - ### mouseEntered

    public void mouseEntered(MouseEvent e)
    Description copied from interface: `MouseListener`
    Invoked when the mouse enters a component.
    Specified by:
      `mouseEntered` in interface `MouseListener`
    Parameters:
      `e` - the event to be processed

  - ### mouseExited

    public void mouseExited(MouseEvent e)
    Description copied from interface: `MouseListener`
    Invoked when the mouse exits a component.
    Specified by:
      `mouseExited` in interface `MouseListener`
    Parameters:
      `e` - the event to be processed

  - ### mousePressed

    public void mousePressed(MouseEvent e)
    Description copied from interface: `MouseListener`
    Invoked when a mouse button has been pressed on a component.
    Specified by:
      `mousePressed` in interface `MouseListener`
    Parameters:
      `e` - the event to be processed

  - ### mouseDragged

    public void mouseDragged(MouseEvent e)
    Description copied from interface: `MouseMotionListener`
    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 interface `MouseMotionListener`
    Parameters:
      `e` - the event to be processed

  - ### mouseMoved

    public void mouseMoved(MouseEvent e)
    Description copied from interface: `MouseMotionListener`
    Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.
    Specified by:
      `mouseMoved` in interface `MouseMotionListener`
    Parameters:
      `e` - the event to be processed

  - ### mouseReleased

    public void mouseReleased(MouseEvent e)
    Description copied from interface: `MouseListener`
    Invoked when a mouse button has been released on a component.
    Specified by:
      `mouseReleased` in interface `MouseListener`
    Parameters:
      `e` - the event to be processed
