I created this class and it worked:
package ve.com.rapipago.pagueaqui.vista.client.componente;
import com.google.gwt.cell.client.AbstractCell;
import com.google.gwt.cell.client.ValueUpdater;
import com.google.gwt.dom.client.Element;
import com.google.gwt.dom.client.NativeEvent;
import com.google.gwt.resources.client.ImageResource;
import com.google.gwt.safehtml.shared.SafeHtml;
import com.google.gwt.safehtml.shared.SafeHtmlBuilder;
import com.google.gwt.safehtml.shared.SafeHtmlUtils;
import com.google.gwt.user.client.ui.AbstractImagePrototype;
public class ClickableImageResourceCell extends AbstractCell<ImageResource>
{
public ClickableImageResourceCell() {
super("click");
}
@Override
public void render(Context context, ImageResource value,
SafeHtmlBuilder sb) {
if (value != null) {
SafeHtml html =
SafeHtmlUtils.fromTrustedString(AbstractImagePrototype.create(value).getHTML());
sb.append(html);
}
}
@Override
public void onBrowserEvent(Context context, Element parent,
ImageResource resource,
NativeEvent event,
ValueUpdater<ImageResource> valueUpdater) {
super.onBrowserEvent(context, parent, resource, event,
valueUpdater);
if ("click".equals(event.getType())) {
onClick(resource, event);
}
}
public void onClick(ImageResource resource,
NativeEvent event) {
}
}
Hope its useful.
