javax.swing.table
类 DefaultTableCellRenderer

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JLabel
                  javax.swing.table.DefaultTableCellRenderer

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

直接已知子类：: DefaultTableCellRenderer.UIResource

public class DefaultTableCellRenderer
extends JLabel
implements TableCellRenderer, Serializable

呈现（显示） JTable 中每个单元格的标准类。

实现注意事项：此类继承自一个标准的组件类 JLabel。但是 JTable 为其单元格的呈现使用了特殊的机制，因此要求稍微对其单元格渲染器的行为进行修改。该 table 类定义一个单元格渲染器，并将其用作呈现表中所有单元格的橡皮图章；它呈现第一个单元格、更改该单元格渲染器的内容、将原点移到新的位置、重新进行绘制，等等。标准的 JLabel 组件不是通过此方式使用的，每次绘制单元格时，我们都希望避免触发 revalidate 事件。这会大大降低程序的性能，因为 revalidate 消息会沿容器的层次结构向上传递，以确定任意其他组件是否将受到影响。由于该渲染器是绘制操作生命周期中唯一的父类，类似地，我们也希望避免与为进行绘制操作而遍历容器层次结构相关联的开销。所以此类将 validate、invalidate、revalidate、repaint 和 firePropertyChange 方法重写为无操作，并单独重写 isOpaque 方法以提高性能。如果您编写自己的渲染器，请记住此性能方面的考虑。

警告：此类的已序列化对象与以后的 Swing 版本不兼容。当前的序列化支持适用于短期存储或运行相同 Swing 版本的应用程序之间的 RMI。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。

字段详细信息

noFocusBorder

protected static Border noFocusBorder

一个空 Border。可以不使用此字段。要更改此渲染器所使用的 Border，请重写 getTableCellRendererComponent 方法并直接设置所返回组件的边界。

构造方法详细信息

public DefaultTableCellRenderer()

创建一个默认的表单元格渲染器。

方法详细信息

setForeground

public void setForeground(Color c)

重写 JComponent.setForeground 将未选定单元格的前景色分配为指定颜色。

覆盖：: 类 JComponent 中的 setForeground

参数：: c - 将前景色设置为此值
另请参见：: Component.getForeground()

setBackground

public void setBackground(Color c)

重写 JComponent.setBackground 将未选定单元格的背景色分配为指定颜色。

覆盖：: 类 JComponent 中的 setBackground

参数：: c - 将背景色设置为此值

返回默认的表单元格渲染器。

在打印操作期间，将调用此方法（isSelected 和 hasFocus 为 false）阻止选择和焦点在打印输出中出现。要根据是否打印表进行其他定制，检查 JComponent.isPaintingForPrint() 的返回值。

指定者：: 接口 TableCellRenderer 中的 getTableCellRendererComponent

参数：: table - JTable; value - 分配给 [row, column] 处单元格的值; isSelected - 如果已选定单元格，则为 true; hasFocus - 如果单元格具有焦点，则为 true; row - 要呈现的单元格所在行; column - 要呈现的单元格所在列
