javax.swing
类 CellRendererPane

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.CellRendererPane

所有已实现的接口：: ImageObserver, MenuContainer, Serializable, Accessible

public class CellRendererPane
extends Container
implements Accessible
extends Container
implements Accessible

此类被插入在单元格渲染器与使用它们的组件之间。它只是为了阻碍 repaint() 和 invalidate() 方法而存在，在配置渲染器时，这些方法将顺着树向上传播。此类用于 JTable、JTree 和 JList 的实现中。例如，以下是绘制 JList 中每个行的代码中使用 CellRendererPane 的方式：

   cellRendererPane = new CellRendererPane();
   ...
   Component rendererComponent = renderer.getListCellRendererComponent();
   renderer.configureListCellRenderer(dataModel.getElementAt(row), row);
   cellRendererPane.paintComponent(g, rendererComponent, this, x, y, w, h);

渲染器组件必须重写 isShowing() 并无条件地返回 true，以便正常运行，因为 Swing paint 在 isShowing 返回 false 时不对组件做任何操作。

警告：此类的已序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储，或适用于在运行相同 Swing 版本的应用程序之间进行 RMI（Remote Method Invocation，远程方法调用）。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeans^TM 长期存储的功能。请参见 XMLEncoder。

嵌套类摘要

构造方法摘要
`CellRendererPane()` 构造一个 CellRendererPane 对象。

方法摘要
`protected void`	`addImpl(Component x, Object constraints, int index)` 如果指定组件已经是此组件的子组件，则不必再操心去做任何事，堆栈顺序对于单元格渲染器组件而言无关紧要（CellRendererPane 不管怎样都不进行绘制）。
`AccessibleContext`	`getAccessibleContext()` 获取与此 CellRendererPane 相关的 AccessibleContext。
`void`	`invalidate()` 重写此方法是为了避免配置单元格渲染器的子级时顺着树向上传播 invalidate。
`void`	`paint(Graphics g)` 不应调用。
`void`	`paintComponent(Graphics g, Component c, Container p, int x, int y, int w, int h)` 调用 this.paintComponent(g, c, p, x, y, w, h, false)。
`void`	`paintComponent(Graphics g, Component c, Container p, int x, int y, int w, int h, boolean shouldValidate)` 在图形对象 g 上绘制一个单元格渲染器组件 c。
`void`	`paintComponent(Graphics g, Component c, Container p, Rectangle r)` 使用矩形的 x、y、width 和 height 字段的调用 this.paintComponent()。
`void`	`update(Graphics g)` 不应调用。

字段详细信息

accessibleContext

protected AccessibleContext accessibleContext

构造方法详细信息

CellRendererPane

public CellRendererPane()

构造一个 CellRendererPane 对象。

方法详细信息

invalidate

public void invalidate()

重写此方法是为了避免配置单元格渲染器的子级时顺着树向上传播 invalidate。

覆盖：: 类 Container 中的 invalidate

另请参见：: Container.validate(), Container.layout(), LayoutManager

paint

public void paint(Graphics g)

不应调用。

覆盖：: 类 Container 中的 paint

参数：: g - 指定的 Graphics 窗口
另请参见：: Component.update(Graphics)

update

public void update(Graphics g)

不应调用。

覆盖：: 类 Container 中的 update

参数：: g - 指定的 Graphics 窗口
另请参见：: Component.update(Graphics)

addImpl

protected void addImpl(Component x,
                       Object constraints,
                       int index)

如果指定组件已经是此组件的子组件，则不必再操心去做任何事，堆栈顺序对于单元格渲染器组件而言无关紧要（CellRendererPane 不管怎样都不进行绘制）。

覆盖：: 类 Container 中的 addImpl

参数：: x - 要添加的组件; constraints - 表示此组件的布局限制的对象
另请参见：: Container.add(Component), Container.add(Component, int), Container.add(Component, java.lang.Object), LayoutManager, LayoutManager2

paintComponent

public void paintComponent(Graphics g,
                           Component c,
                           Container p,
                           int x,
                           int y,
                           int w,
                           int h,
                           boolean shouldValidate)

在图形对象 g 上绘制一个单元格渲染器组件 c。在绘制该组件之前，要对此方法进行 reparent 操作（如有必要），将其边界设置为 w,h 并且将图形对象（有效地）转换成 x,y。如果该对象是一个 JComponent，则暂时关闭双重缓冲。在绘制组件之后，将边界重新设置为 -w, -h, 0, 0。因此，如果该组件是最后一个被绘制的渲染器组件，那么它不会开始使用输入。Container p 是我们实际要绘制的组件，通常它等于 this.getParent()。如果 shouldValidate 为 true，则组件 c 将在绘制之前被验证。

paintComponent

public void paintComponent(Graphics g,
                           Component c,
                           Container p,
                           int x,
                           int y,
                           int w,
                           int h)

调用 this.paintComponent(g, c, p, x, y, w, h, false)。

paintComponent

public void paintComponent(Graphics g,
                           Component c,
                           Container p,
                           Rectangle r)

使用矩形的 x、y、width 和 height 字段的调用 this.paintComponent()。

getAccessibleContext

public AccessibleContext getAccessibleContext()

获取与此 CellRendererPane 相关的 AccessibleContext。对于 CellRendererPanes，AccessibleContext 采用 AccessibleCellRendererPane 的形式。如有必要，可创建一个新的 AccessibleCellRendererPane 实例。

指定者：: 接口 Accessible 中的 getAccessibleContext
覆盖：: 类 Component 中的 getAccessibleContext

返回：: 一个 AccessibleCellRendererPane，它可用作此 CellRendererPane 的 AccessibleContext
