function getUrl(tabId)?

Is it possible to get the URL of the page loaded in a particular tab?



My tabbar is in iframes-href-mode.

You can get it as
    tabbar._hrefs[id]
where id - id of tab in question

Please beware that it will be url set by script, if it was changed later ( by links in iframe ) - you can get actual value as
   
    tabbar.tabWindow(id).document.location.href
