    event - The object providing details of the mouse event.
  - getPreferredScrollableViewportSize
```
public java.awt.Dimension getPreferredScrollableViewportSize()
```
    Returns the preferred size of the viewport for a view component. For example the preferredSize of a JList component is the size required to accommodate all of the cells in its list however the value of preferredScrollableViewportSize is the size required for JList.getVisibleRowCount() rows. A component without any properties that would effect the viewport size should just return getPreferredSize() here.
    
    指定者:
    
    getPreferredScrollableViewportSize 在接口中 javax.swing.Scrollable
    
    返回:
    
    The preferredSize of a JViewport whose view is this Scrollable.
    
    另请参阅:
    
    JComponent.getPreferredSize()
  - getScrollableUnitIncrement
```
public int getScrollableUnitIncrement(java.awt.Rectangle visibleRect,
                                      int orientation,
                                      int direction)
```
    Components that display logical rows or columns should compute the scroll increment that will completely expose one new row or column, depending on the value of orientation. Ideally, components should handle a partially exposed row or column by returning the distance required to completely expose the item.
    Scrolling containers, like JScrollPane, will use this method each time the user requests a unit scroll.
    
    指定者:
    
    getScrollableUnitIncrement 在接口中 javax.swing.Scrollable
    
    参数:
    
    visibleRect - The view area visible within the viewport
    
    orientation - Either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL.
    
    direction - Less than zero to scroll up/left, greater than zero for down/right.
    
    返回:
    
    The "unit" increment for scrolling in the specified direction. This value should always be positive.
  - getScrollableBlockIncrement
```
public int getScrollableBlockIncrement(java.awt.Rectangle visibleRect,
                                       int orientation,
                                       int direction)
```
    Components that display logical rows or columns should compute the scroll increment that will completely expose one block of rows or columns, depending on the value of orientation.
    Scrolling containers, like JScrollPane, will use this method each time the user requests a block scroll.
    
    指定者:
    
    getScrollableBlockIncrement 在接口中 javax.swing.Scrollable
    
    参数:
    
    visibleRect - The view area visible within the viewport
    
    orientation - Either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL.
    
    direction - Less than zero to scroll up/left, greater than zero for down/right.
    
    返回:
    
    The "block" increment for scrolling in the specified direction. This value should always be positive.
  - getScrollableTracksViewportWidth
```
public boolean getScrollableTracksViewportWidth()
```
    Return true if a viewport should always force the width of this Scrollable to match the width of the viewport. For example a normal text view that supported line wrapping would return true here, since it would be undesirable for wrapped lines to disappear beyond the right edge of the viewport. Note that returning true for a Scrollable whose ancestor is a JScrollPane effectively disables horizontal scrolling.
    Scrolling containers, like JViewport, will use this method each time they are validated.
    
    指定者:
    
    getScrollableTracksViewportWidth 在接口中 javax.swing.Scrollable
    
    返回:
    
    true if a viewport should force the Scrollables width to match its own.
  - getScrollableTracksViewportHeight
```
public boolean getScrollableTracksViewportHeight()
```
    Return true if a viewport should always force the height of this Scrollable to match the height of the viewport. For example a columnar text view that flowed text in left to right columns could effectively disable vertical scrolling by returning true here.
    Scrolling containers, like JViewport, will use this method each time they are validated.
    
    指定者:
    
    getScrollableTracksViewportHeight 在接口中 javax.swing.Scrollable
    
    返回:
    
    true if a viewport should force the Scrollables height to match its own.
  - componentResized
```
public void componentResized(java.awt.event.ComponentEvent event)
```
    Invoked when the container's size changes. Un-caches the preferred size.
    
    指定者:
    
    componentResized 在接口中 java.awt.event.ComponentListener
    
    参数:
    
    event - The resize event.
  - componentMoved
```
public void componentMoved(java.awt.event.ComponentEvent event)
```
    Invoked when the component's position changes. Not used.
    
    指定者:
    
    componentMoved 在接口中 java.awt.event.ComponentListener
    
    参数:
    
    event - The component event.
  - componentShown
```
public void componentShown(java.awt.event.ComponentEvent event)
```
    Invoked when the component has been made visible. Not used.
    
    指定者:
    
    componentShown 在接口中 java.awt.event.ComponentListener
    
    参数:
    
    event - The component event.
  - componentHidden
```
public void componentHidden(java.awt.event.ComponentEvent event)
```
    Invoked when the component has been made invisible. Not used.
    
    指定者:
    
    componentHidden 在接口中 java.awt.event.ComponentListener
    
    参数:
    
    event - The component event.
  - hierarchyChanged
```
public void hierarchyChanged(java.awt.event.HierarchyEvent event)
```
    Handles this components ancestor being added to a container. Registers this component as a listener for size changes on the ancestor so that we may un-cache the prefereed size and force a recalculation.
    
    指定者:
    
    hierarchyChanged 在接口中 java.awt.event.HierarchyListener
    
    参数:
    
    event - The heirarchy event.
