Have you looked at the xpcom tutorial, WebLock? (http://www.mozilla.org/projects/xpcom/book/cxc/). The example built in the document uses the nsIObserverService to register for events and when certain events occur, say loading a new url, all registered observers are notified. If this won't work for you, there may be a xpcom browser object (probably a service???) that will give you a pointer to the browser which in turn may contain functions for things like getting the current url. I found an object called nsIBrowserHistory that has an attribute of type utf8string called something like getLastUrl, but the interface does not appear to be frozen.... At any rate, take a look at the weblock tutorial. It's very long but helpful.
How will your xpcom object be invoked? Knowing how/when the object is created will help determine possible solutions to your problem. dupes _______________________________________________ Mozilla-xpcom mailing list Mozilla-xpcom@mozilla.org http://mail.mozilla.org/listinfo/mozilla-xpcom
