default-page-width

Arguments: window interior-width scrollbarp

Returns a default page-width to use for window when no page-width has been explicitly specified with either a setf of the page-width function or the :page-width initarg. interior-width is the interior width of the window. scrollbarp is true if the horizontal 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-width if the scrollbar is not enabled, and otherwise returns the width of the screen. An application may add default-page-width methods to define default page-widths for its own window classes. The method should always return a width and never return nil.
