示例1: setComponent
import java.awt.Component; //导入方法依赖的package包/类
/**
* Set the cell renderer we will proxy.
*/
public void setComponent (Component jc, JComponent owner) {
Dimension dd = jc.getPreferredSize();
Rectangle currentScreenBounds = Utilities.getUsableScreenBounds();
// get some reasonable limit for the width
int width = Math.min(dd.width, 2 * currentScreenBounds.width);
int height = Math.min(dd.height + 2, 2 * currentScreenBounds.height);
Image nue = !Utilities.isMac() ? owner.createVolatileImage(width, height) :
