示例1: dispose
import org.eclipse.swt.graphics.Image; //导入方法依赖的package包/类
@Override
public void dispose(TableCell cell) {
// only dispose of image here, this method is reused in other methods
Graphic graphic = cell.getGraphic();
if (graphic instanceof UISWTGraphic)
{
final Image img = ((UISWTGraphic) graphic).getImage();
if (img != null && !img.isDisposed()){
img.dispose();
// see http://forum.vuze.com/thread.jspa?threadID=117243
// could it be that it isn't being marked as disposed after disposal and
// being double-disposed?
((UISWTGraphic) graphic).setImage( null );
