These scrollbars are part of the embedded native Browser, they're not available to us the way they are on other controls like Table, List, etc.  What do you want to do with them?  You may be able to achieve what you want via javascript.

Ah I see. I would like to be notified when the user scrolls the browser. Is this possible?

Thank you
Misha

It looks like Javascript's window object offers an onscroll event, so you should be able to add a listener for this on every page load (detect this by ProgressListener.completed()) via Browser.execute(...).

If you want this notification to get out to your java code then you can define a BrowserFunction when your Browser is first instantiated, and have your javascript scroll listener invoke this function.  For a BrowserFunction example see http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet307.java?view=co .

Thank you. That is very helpful.

I have completely re-written my EPL-licensed Web Automation Framework so that we actually get a Java DOM representation of the page.

I hope that it will be useful, and I hope to release in next few days.

Thank you so much for all your help.
