+In prototype versions of the \*(tk
+each widget class
+implemented an Xt<\^\fIWidget\fP\^>Create (for example,
+.PN XtLabelCreate )
+function, in which most of the code was identical from widget to widget.
+In the \*(xI, a single generic
+.PN XtCreateWidget
+performs most of the common work and then calls the initialize procedure
+implemented for the particular widget class.
+.LP
+Each Composite class also implemented the procedures
+Xt<\^\fIWidget\fP\^>Add and an Xt<\^\fIWidget\fP\^>Delete (for example,
+.PN XtButtonBoxAddButton
+and
+.PN XtButtonBoxDeleteButton ).
+In the \*(xI, the Composite generic procedures
+.PN XtManageChildren
+and
+.PN XtUnmanageChildren
+perform error checking and screening out of certain children.
+Then they call the change_managed procedure
+implemented for the widget's Composite class.
+If the widget's parent has not yet been realized,
+the call to the change_managed procedure is delayed until realization time.
+.LP
+Old-style calls can be implemented in the \*(tk by defining
+one-line procedures or macros that invoke a generic routine. For example,
+you could define the macro
+.PN XtLabelCreate
+as:
