Mark, 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?

(maybe > also key events for elements like buttons) 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 >) calls into EventHandler::mouseDown >(<http://trac.webkit.org/browser/trunk/WebCore/page/mac/EventHandlerMac.mm?rev=36685#L474 > >), which then calls into the cross-platform EventHandler::handleMousePressEvent (<http://trac.webkit.org/browser/trunk/WebCore/page/EventHandler.cpp?rev=36685#L317 >). EventHandler then takes care of the necessary text selection, dispatch of DOM events, etc. Hope this helps, - Mark
