default-page-height

Arguments: window interior-height scrollbarp

Returns a default page-height to use for window when no page-height has been explicitly specified with either a setf of the page-height function or the :page-height initarg. interior-height is the interior height of the window. scrollbarp is true if the vertical scrollbar was enabled for the window when it was created. The returned value is always in stream units (see cg-coordinates.htm).

The default method returns the interior-height if the scrollbar is not enabled, and otherwise returns the height of the screen. An application may add default-page-height methods to define default page-heights for its own window classes. The method should always return a height and never return nil.
