OK, I whipped this up for you. It should get you close to what you
want to do. The downside will be that you may have to have a 'visible'
widget (in this case a transparent image) to anchor.
import java.util.HashMap;
import com.google.gwt.user.client.DOM;
import com.google.gwt.user.client.ui.ClickListener;
import com.google.gwt.user.client.ui.Image;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.Widget;
public class AnchorManager {
private HashMap<String, Widget> anchors = new HashMap<String, Widget>
();
public Widget createLink(String text, final String anchorName) {
Label lbl = new Label(text);
lbl.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
try {
showAnchor(anchorName);
} catch (Exception e) {
// TODO: handle Exception
}
}
});
return lbl;
}
public Widget createAnchorWidget(String name) throws Exception {
if (!anchors.containsKey(name)) {
return new Image("pixel.gif"); // really should use
image bundle
} else {
throw new Exception("Anchor already exists");
}
}
public void showAnchor(String name) throws Exception {
if (anchors.containsKey(name)) {
DOM.scrollIntoView(anchors.get(name).getElement());
} else {
throw new Exception("Anchor does not exists");
}
}
}
