Hi javaunixsolaris-
I'm not exactly sure what your question is. The "history way" is not
new in GWT 2.0. Read about it here:
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html
If you want to know how to use an <a> element that handles clicks AND
changes history, I believe the @deprecated comment for
Hyperlink.addClickHandler() implies you should extend FocusWidget and
use its addClickHandler(). Something like this:
public class MyHyperlink extends FocusWidget {
public MyHyperlink(String text) {
super(DOM.createAnchor());
// set the text
}
// you should cherry-pick the methods implemented in Hyperlink
// you want, like setTargetHistoryToken(), and impl them here
}
MyHyperlink link = new MyHyperlink("text");
link.addClickHandler(...);
However, I have not tried or tested this, so I'm not sure that's the
best way. A specific use case might help :).
