GWT Places/Activities - what should be used for navigation?

Question

I have a GWT Places/Activities web application. I use Anchor's click event to move user in a new "place", so there's no way user can open any "link" in a new window or tab. The question is - how do I make all these links real?

Answer 1

Maybe instead of using Anchor and listening to the ClickEvent use Hyperlink with the targetHistoryToken set to the Place name.

e.g.

<g:Hyperlink text="Home" targetHistoryToken="home" />

Answer 2

While using a Hyperlink (or InlineHyperlink) works, I'd rather use a ClickHandler on an Anchor, because if any activity returns a non-null value in mayStop the URL wouldn't have changed yet (whereas with a Hyperlink, it would have, even if the user chooses to cancel the navigation).

To set the target (href) on the Anchor, simply use your PlaceHistoryMapper. And to correctly handle the ctrl+click, middle-click and right-click, reuse the HyperlinkImpl:

Anchor anchor = new Anchor("text", "#" + placeHistoryMapper.getToken(targetPlace));
anchor.addClickHandler(new ClickHandler() {
   private static final HyperlinkImpl IMPL = GWT.create(HyperlinkImpl.class);

   @Override
   public void onClick(ClickEvent event) {
      if (IMPL.handleAsClick(event)) {
         placeController.goTo(targetPlace);
         event.preventDefault();
      }
   }
});
