...and the answer is:
Make a TreeImages descendant that uses transparent images for the
"knees".
interface NoKneesTreeImages extends TreeImages {
@Resource("dk/ange/gwt/dataqualitybrowser/public/images/
transparent-16x16.gif")
public AbstractImagePrototype treeClosed();
@Resource("dk/ange/gwt/dataqualitybrowser/public/images/
transparent-16x16.gif")
public AbstractImagePrototype treeOpen();
}
Use it when constructing the Tree.
private final TreeImages images = (TreeImages)GWT.create
(NoKneesTreeImages.class);
private final Tree actionsTree = new Tree(images);
You will need a small, transparent gif or png image.
Please remember to modify the paths to the images to reflect you own
package structure.
