well you dont event need to override the onBrowserEvent method :)
MyTreeImages treeimages = GWT.create(MyTreeImages.class);
Tree tree = new Tree(treeimages);
//tree.addOpenHandler(handler);
tree.setAnimationEnabled(true);
TreeNode node = new TreeNode(result.get(i));
node.addClickHandler(SMDesigner_gwt.handler);
TreeItem item = new TreeItem(node);
node.setItemTree(item);
item.addItem("loading...");
tree.addItem(item);
treePanel.add(tree);
MyTreeImages is an interface that override the tree images, it contains the
following:
@Override
@Source("space.png")
public ImageResource treeClosed();
@Override
@Source("space.png")
public ImageResource treeLeaf();
@Override
@Source("space.png")
public ImageResource treeOpen();
where space is 1x1 pixel image.
and TreeNode constructor has the a POJO class as param to pass the name and
image fetched from db
public TreeNode(EntityTree entityTree){
super();
this.entityTree = entityTree;
HTML html = new HTML(entityTree.getName());
this.setWidget(html);
this.getElement().getStyle().setBackgroundImage("url("+entityTree.getIconUrl()+")");
this.getElement().getStyle().setPaddingLeft(20, Unit.PX);
this.setStyleName("treeNode");
}
hope that it is clear enough to get the idea.
