I haven't tried it but this might work
public class BooleanImageColumn extends PropertyColumn<Boolean> {
private static final long serialVersionUID = 1L;
private static final ResourceReference TRUE_IMG = new
ResourceReference(BooleanImageColumn.class, "true.gif");
private static final ResourceReference FALSE_IMG = new
ResourceReference(BooleanImageColumn.class, "false.gif");
public BooleanImageColumn(IModel<String> displayModel, String
propertyExpression) {
super(displayModel, propertyExpression);
}
public BooleanImageColumn(IModel<String> displayModel, String
sortProperty, String propertyExpression) {
super(displayModel, sortProperty, propertyExpression);
}
@Override
public void populateItem(Item<ICellPopulator<Boolean>> item, String
componentId, IModel<Boolean> rowModel) {
if(rowModel.getObject() == null ||
rowModel.getObject().equals(Boolean.FALSE))
item.add(new NonCachingImage(componentId, FALSE_IMG));
else
item.add(new NonCachingImage(componentId, TRUE_IMG));
}
}
Just place a "true.gif" and a "false.gif" on the same package as
BooleanImageColumn.
