static and inline are redundant.

This switch statement is not in the proper style.

Why are you creating these CStrings?  You can just return pointers to the string literals.

reinterpret_cast -> static_cast

Please read up on the differences between these two kinds of C++ casts, especially as they related to multi-inheritance.  Using the wrong cast can result is subtle, dangerous bugs!

Fixed (also fixed the other cases of the same issue in this file).

Fixed.

Whoops. My bad. Fixed. Thanks!

This function should probably be static

> Tools/DumpRenderTree/chromium/TestWebPlugin.cpp:99
> +void printTouchList(const WebKit::WebTouchPoint* points, int length)

ditto

> Tools/DumpRenderTree/chromium/TestWebPlugin.cpp:105
> +void printEventDetails(const WebKit::WebInputEvent& event)

ditto
