-// ClientView
-//
-//  A ClientView is a View subclass that is used to occupy the "client area"
-//  of a widget. It provides basic information to the widget that contains it
-//  such as non-client hit testing information, sizing etc. Sub-classes of
-//  ClientView are used to create more elaborate contents, e.g.
-//  "DialogClientView".
-class VIEWS_EXPORT ClientView : public View {
- public:
-  // Internal class name
-  static const char kViewClassName[];
-
-  // Constructs a ClientView object for the specified widget with the specified
-  // contents. Since this object is created during the process of creating
-  // |widget|, |contents_view| must be valid if you want the initial size of
-  // the widget to be based on |contents_view|'s preferred size.

-  // Tests to see if the specified point (in view coordinates) is within the
-  // bounds of this view. If so, it returns HTCLIENT in this default
-  // implementation. If it is outside the bounds of this view, this must return
-  // HTNOWHERE to tell the caller to do further processing to determine where
-  // in the non-client area it is (if it is).
-  // Subclasses of ClientView can extend this logic by overriding this method
-  // to detect if regions within the client area count as parts of the "non-
-  // client" area. A good example of this is the size box at the bottom right
-  // corner of resizable dialog boxes.
