Right, HyperlinkImpl should be made somehow public so it would be safe
to use it with Anchor (safe meaning here forwards-compatible; it could
be a public static method of Anchor for instance, hiding the use of
HyperlinkImpl). (may I suggest you file an issue ;-) )
Anchor tagCloud = ...;
tagCloud.addClickHandler(new ClickHandler() {
HyperlinkImpl impl = GWT.create(HyperlinkImpl.class);
public void onClick(ClickEvent event) {
if (impl.handleAsClick(event.getNativeEvent().cast())) {
TagPopup.this.hide();
History.newItem("tagcloudToken");
}
}
});
The above works right now, and with a public static method, it would
turn into:
...
if (Anchor.handleAsClick(event)) {
...
which is much more readable ;-)
