java.lang.Object java.awt.Component java.awt.Container javax.swing.CellRendererPane
public class CellRendererPane
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 JavaBeansTM 长期存储的功能。请参见 XMLEncoder

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。 |
