Ops. My mistake, wrong answer of the right question :).
Sorry about that.
So I think that you could define your own custom widget that is using
several existing widgets that are looking similar to that you wanna
build.
You could extend the Composite widget and to combine other several
widgets together on it. Here is some example that would make the things
more clear (note that code is not compiled and may contains some
mistakes):
public class MyListBox extends Composite {
private Button showListButton = new Button("");
private MyListBoxListItemsView items = new MyListBoxListItemsView();
private HorizontalPanel container = new HorizontalPanel();
public MyListBox(MyObject[] items) {
initWidget(container);
showListButton.setStyleName("myListBoxButton"); // set background
image and etc
this.items.addAll(items);
showListButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent e) {
if (!items.showed()) {
items.showList();
} else {
items.hideList(); // second button click have to hide list
items
}
}
})
container.add(items);
container.add(showListButton);
}
}
and so on.
Hope this will help you to solve your issue.
Also You can look at the showcase example:
http://gwt.google.com/samples/Showcase/Showcase.html
You could use Basic Popup for showing and hiding list items to the
user.(i.e in my example:showListButton could show and hide the Basic
Popup widget with rendered items)
Another option would be using of existing js widget and binding them
through JSNI, but I think that it's a little bit harder then using GWT's
widget library.

Miroslav
