Thanks a lot. I'm still wondering how the Mouse/Key events are associated with the Render Tree? i.e, how thoses events are routed to every render node?
I saw there is a "Widget" class implemented for different platforms, and also RenderWidget. seems there is something (specific to mouse events) happening while building up the render tree?

WebCore doesn't register for mouse events, the WebKit layer takes care
of passing mouse events down to WebCore when needed. For example,
when a button is pressed WebKit on Mac (<http://trac.webkit.org/browser/trunk/WebKit/mac/WebView/WebHTMLView.mm?rev=36685#L3132

dispatch of DOM events, etc.
Hope this helps,
