- All Implemented Interfaces:
ImageObserver
,MenuContainer
,Serializable
,Accessible
This class is inserted in between cell renderers and the components that
use them. It just exists to thwart the repaint() and invalidate() methods
which would otherwise propagate up the tree when the renderer was configured.
It's used by the implementations of JTable, JTree, and JList. For example,
here's how CellRendererPane is used in the code the paints each row
in a JList:
cellRendererPane = new CellRendererPane(); ... Component rendererComponent = renderer.getListCellRendererComponent(); renderer.configureListCellRenderer(dataModel.getElementAt(row), row); cellRendererPane.paintComponent(g, rendererComponent, this, x, y, w, h);
A renderer component must override isShowing() and unconditionally return true to work correctly because the Swing paint does nothing for components with isShowing false.
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.
