18 //
19 // A ClientView is a View subclass that is used to occupy the "client area"
20 // of a widget. It provides basic information to the widget that contains it
21 // such as non-client hit testing information, sizing etc. Sub-classes of
22 // ClientView are used to create more elaborate contents, e.g.
23 // "DialogClientView".

26 // Internal class name

29 // Constructs a ClientView object for the specified widget with the specified
30 // contents. Since this object is created during the process of creating
31 // |widget|, |contents_view| must be valid if you want the initial size of
32 // the widget to be based on |contents_view|'s preferred size.

52 // HTNOWHERE to tell the caller to do further processing to determine where
53 // in the non-client area it is (if it is).
54 // Subclasses of ClientView can extend this logic by overriding this method
55 // to detect if regions within the client area count as parts of the "non-
56 // client" area. A good example of this is the size box at the bottom right
