+.SH DESCRIPTION
+The
+.ZN XtManageChildren
+function performs the following:
+.IP \(bu 5
+Issues an error if the children do not all have the same parent or
+if the parent is not a subclass of
+.ZN compositeWidgetClass .
+.IP \(bu 5
+Returns immediately if the common parent is being destroyed;
+otherwise, for each unique child on the list,
+.ZN XtManageChildren
+ignores the child if it already is managed or is being destroyed
+and marks it if not.
+.IP \(bu 5
+If the parent is realized and after all children have been marked,
+it makes some of the newly managed children viewable:
+.RS
+.IP \- 5
+Calls the change_managed routine of the widgets' parent.
+.IP \- 5
+Calls
+.ZN XtRealizeWidget
+on each previously unmanaged child that is unrealized.
+.IP \- 5
+Maps each previously unmanaged child that has map_when_managed
+.ZN True .
+.RE
+.LP
+Managing children is independent of the ordering of children and
+independent of creating and deleting children.
+The layout routine of the parent
+should consider children whose managed field is
+.ZN True
+and should ignore all other children.
+Note that some composite widgets, especially fixed boxes, call
+.ZN XtManageChild
+from their insert_child procedure.
+.LP
+If the parent widget is realized,
+its change_managed procedure is called to notify it
+that its set of managed children has changed.
+The parent can reposition and resize any of its children.
+It moves each child as needed by calling
+.ZN XtMoveWidget ,
+which first updates the x and y fields and then calls
+.ZN XMoveWindow
+if the widget is realized.
+.LP
+The
+.ZN XtManageChild
+function constructs a
+.ZN WidgetList
+of length one and calls
+.ZN XtManageChildren .
+.LP
+The
+.ZN XtUnmanageChildren
+function performs the following:
+.IP \(bu 5
+Issues an error if the children do not all have the same parent
+or if the parent is not a subclass of
+.ZN compositeWidgetClass .
+.IP \(bu 5
+Returns immediately if the common parent is being destroyed;
+otherwise, for each unique child on the list,
+.ZN XtUnmanageChildren
+performs the following:
+.RS
+.IP \- 5
+Ignores the child if it already is unmanaged or is being destroyed
+and marks it if not.
+.IP \- 5
+If the child is realized,
+it makes it nonvisible by unmapping it.
+.RE
+.IP \(bu 5
+Calls the change_managed routine of the widgets' parent
+after all children have been marked
+if the parent is realized.
+.LP
+.ZN XtUnmanageChildren
+does not destroy the children widgets.
+Removing widgets from a parent's managed set is often a temporary banishment,
+and, some time later, you may manage the children again.
+.LP
+The
+.ZN XtUnmanageChild
+function constructs a widget list
+of length one and calls
+.ZN XtUnmanageChildren .
+.LP
+The
+.ZN XtChangeManagedSet
+function performs the following:
+.IP \(bu 5
+Issues an error if the widgets specified in the \fImanage_children\fP
+and the \fIunmanage_children\fP lists to no all have the same parent, or
+if that parent is not a subclass of compositeWidgetClass.
+.IP \(bu 5
+Returns immediately if the common parent is being destroyed.
+.IP \(bu 5
+If no
+.ZN CompositeClassExtension
+is defined, or a
+.ZN CompositeClassExtension
+is defined but with an \fIallows_change_managed_set\fP field with a
+value of
+.ZN False ,
+and
+.ZN XtChangeManagedSet
+was invoked with a non-NULL \fIpost_unmanage_pre_manage_hook\fP procedure
+then
+.ZN XtChangeManagedSet
+performs the following:
+.RS
+.IP \- 5
+Calls
+.ZN XtUnmanageChildren
+(\fIunmanage_children\fP, \fInum_unmanage_children\fP).
+.IP \- 5
+Calls the \fIpost_unmanage_pre_manage_hook\fP specified.
+.IP \- 5
+Calls
+.ZN XtManageChildren
+(\fImanage_children\fP, \fInum_manage_children\fP) and then returns
+immediately.
+.RE
+.IP \(bu 5
+Otherwise, if a
+.ZN CompositeClassExtension
+is defined with an \fIallows_change_managed_set\fP field with a value of
+.ZN True ,
+or if no
+.ZN CompositeClassExtension
+is defined, and
+.ZN XtChangeManagedSet was invoked with a NULL
+\fIpost_unmanage_pre_manage_hook\fP procedure, then the following is
+performed:
+.RS
+.IP \- 5
+For each child on the \fIunmanage_children\fP list; if the child is
+already unmanaged or is being destroyed it is ignored, otherwise it
+is marked as being unmanaged and if it is realized it is made nonvisible
+by being unmapped.
+.IP \- 5
+If the \fIpost_unmanage_pre_manage_hook\fP procdedure is non-NULL then
+it is invoked as specified.
+.IP \- 5
+For each child on the \fImanage_children\fP list; if the child is
+already managed or it is being destroyed it is ignored, otherwise it
+is marked as managed
+.RE
+.IP \(bu 5
+If the parent is realized and after all children have been marked, the
+change_managed method of the parent is invoked and subsequently some
+of the newly managed children are made viewable by:
+.RS
+.IP \- 5
+Calling
+.ZN XtRealizeWidget
+on each of the previously unmanaged child that is unrealized.
+.IP \- 5
+Mapping each previously unmanaged child that has \fImap_when_managed\fP
+.ZN True .
+.RE
+.LP
+The
+.ZN XtIsManaged
+function returns
+.ZN True
+if the specified widget is of class RectObj or any subclass thereof and
+is managed, or
+.ZN False
+otherwise.
