Thank you.

I put debug print statement in each of the 'case' statement inside:

bool RenderTheme::paint(RenderObject* o, const
RenderObject::PaintInfo& paintInfo, const IntRect& r)

When I load "www.google.com", the only printfs I see is under
  case MenulistButtonPart:
        case TextFieldPart:
        case TextAreaPart:
        case ListboxPart:
			cout << " Calling MenulistButtonPart, TextFieldPart, TextAreaPart,
ListboxPart " << endl;
            return true;

I assume that is for the search box of www.google.com, but why I don't
see any printf for the input buttons?
I have printf in
        case PushButtonPart:
        case SquareButtonPart:
        case ListButtonPart:
        case DefaultButtonPart:
        case ButtonPart:
	  cout << " Calling paintButton " << endl;
            return paintButton(o, paintInfo, r);
