XtDoChangeProc(3X)		 XT FUNCTIONS		    XtDoChangeProc(3X)

NAME
       XtDoChangeProc - procedure used by XtChangeManagedSet to make changes
       to children

SYNTAX
       typedef void (XtDoChangeProc*)(Widget, WidgetList, Cardinal*, Wid‐
       getList, Cardinal*. XtPointer);
	     Widget composite_parent;
	     WidgetList unmanage_children;
	     Cardinal *num_unmanage_children;
	     WidgetList manage_children;
	     Cardinal *num_manage_children;
	     XtPointer client_data;

ARGUMENTS
       composite_parent
		 Passes the composite parent whose managed set is being
		 altered.

       unmanage_children
		 Passes the list of children just removed from the managed
		 set.

       num_unmanage_children
		 Passes the number of entries in the un_manage_children list.

       manage_children
		 Passes the list of children about to be added to the managed
		 set.

       num_manage_children
		 Passes the number of entries in the manage_children list.

       client_data
		 Passes the client data passed to XtChangeManagedSet.

DESCRIPTION
       XtDoChangeProc is used by the caller of XtChangeManagedSet() to make
       changes to one or more children at the point when the managed set con‐
       tains the fewest entries. These changes may involve geometry requests
       and in this case the caller of XtChangeMangedSet may take advantage of
       the fact that the Intrinsics internally grant geometry requests made by
       unmanaged children without invoking the parent's geometry manager. To
       achieve this advantage, if the do_change_proc procedure changes the
       geometry of a child or of a descendent of a child, then that should be
       included in the unmanage_children and manage_children lists.
