The widget's class can be any number of subclasses +down the chain and need not be an immediate subclass of the specified +class. Composite widgets that need to restrict the class of the items +they contain can use +.ZN XtIsSubclass +to find out if a widget belongs to the desired class of objects. +.LP +The +.ZN XtCheckSubclass +macro determines if the class of the specified widget is equal to +or is a subclass of the specified widget class. +The widget can be any number of subclasses down the chain +and need not be an immediate subclass of the specified widget class. +If the specified widget is not a subclass, +.ZN XtCheckSubclass +constructs an error message from the supplied message, +the widget's actual class, and the expected class and calls +.ZN XtErrorMsg . +.ZN XtCheckSubclass +should be used at the entry point of exported routines to ensure +that the client has passed in a valid widget class for the exported operation. +.LP +.ZN XtCheckSubclass +is only executed when the widget has been compiled with the compiler symbol +DEBUG defined; otherwise, it is defined as the empty string +and generates no code. +.LP +To test if a given widget belongs to a subclass of an Intrinsics-defined +class, the Intrinsics defines macros or functions equivalent to +.ZN XtIsSubclass +for each of the built-in classes.
