I think you'll want to make this:

class CONTENT_EXPORT TextSurroundingsDelegate {

You'll need to add the "content/common/content_export.h" include.

Done.

+ public:
+  virtual void OnTextSurroundingSelectionResponse(const base::string16& content,
+                                                  int start_offset,
+                                                  int end_offset) = 0;
+ protected:
+  virtual ~TextSurroundingsDelegate() {}
+};
+
+}  // namespace content

Nit: Newline before the #endif.

Done.
