It's my understanding you shouldn't do this. Only virtual methods you can inline
are void.

You're right, it's in our style guide! Reverted this bit.

 
   // Execute context menu command specified by |command_id|.
   virtual void ExecuteCommand(int command_id) {}
 
  protected:
   virtual ~TextfieldController() {}
 };
 
 }  // namespace views
