I'm just digging around GWT-EXT, and trying to do something as silly as create a HyperLink, but there is no HyperLink class defined! The Google Web Toolkit extensions seem to define everything from a Button to a Toolbar, but nothing in the realm of the simple HyperLink. Hmmm?
Of course, I'm sure there is something I'm missing here. I spent a silly amount of time trying to figure out how to put a GWT image inside a GWT hyperlink to make the image clickable. Of course, in the end, you just add a ClickHandler to the image - no GWT HtmlLink object is needed at all.
