Re: How to format custom TreeItems with images?

Instead of constructing your TreeItems with html, write your own
custom tree item renderer and pass it in to the TreeItem(Widget)
constructor.

http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/user/client/ui/TreeItem.html

My TreeItemRenderer extends HorizontalPanel, but you can use any
Widget that works for you.
