LIBRARY CALL
int xvw_check_subclass(
xvobject object,
xvclass wclass)
INPUT
object - object for which to check the subclass
class - the class to be checked for
OUTPUT
none
RETURN VALUE
TRUE if the object has the specified subclass,
FALSE otherwise
DESCRIPTION
Checks if the object has the specified subclass.
Example1: if the object passed in was a zoom object,
and the class given was ImageClass, the routine
would return TRUE since the zoom object is subclassed
off the image object. Example2: if the object passed
in was a zoom object, and the class given was ColorClass,
the routine would return TRUE, since the zoom object
is subclassed off the image object and the image object
is subclassed off the color object. Example3: if the
object passed in was a zoom object, and the class given
was PanIconClass, the routine would return FALSE, since
the PanIconClass does not appear in the inheritance tree
of the zoom object.
