 NAME    [Toc]    [Back]
      MrmFetchSetValues - Fetches the values to be set from literals stored
      in UID files

 SYNOPSIS    [Toc]    [Back]
      #include <Mrm/MrmPublic.h>
      Cardinal MrmFetchSetValues(
      MrmHierarchy hierarchy_id,
      Widget widget,
      ArgList args,
      Cardinal num_args);

 DESCRIPTION    [Toc]    [Back]
      The MrmFetchSetValues function is similar to XtSetValues, except that
      the values to be set are defined by the UIL named values that are
      stored in the UID hierarchy.  MrmFetchSetValues fetches the values to
      be set from literals stored in UID files.

      hierarchy_id
                Specifies the ID of the UID hierarchy that contains the
                specified literal.  The value of hierarchy_id was returned
                in a previous call to MrmOpenHierarchyPerDisplay.

      widget    Specifies the widget that is modified.

      args      Specifies an argument list that identifies the widget
                arguments to be modified as well as the index (UIL name) of
                the literal that defines the value for that argument.  The
                name part of each argument (args[n].name) must begin with
                the string XmN followed by the name that uniquely identifies
                this attribute tag.  For example, XmNwidth is the attribute
                name associated with the core argument width.  The value
                part (args[n].value) must be a string that gives the index
                (UIL name) of the literal.  You must define all literals in
                UIL as exported values.

      num_args  Specifies the number of entries in args.

      This function sets the values on a widget, evaluating the values as
      public literal resource references resolvable from a UID hierarchy.
      Each literal is fetched from the hierarchy, and its value is modified
      and converted as required.  This value is then placed in the argument
      list and used as the actual value for an XtSetValues call.
      MrmFetchSetValues allows a widget to be modified after creation using
      UID file values the same way creation values are used in
      MrmFetchWidget.

      As in MrmFetchWidget, each argument whose value can be evaluated from
      the UID hierarchy is set in the widget.  Values that are not found or
      values in which conversion errors occur are not modified.

      Each entry in the argument list identifies an argument to be modified
      in the widget.  The name part identifies the tag, which begins with
      XmN.  The value part must be a string whose value is the index of the
      literal.  Thus, the following code would modify the label resource of
      the widget to have the value of the literal accessed by the index
      OK_button_label in the hierarchy:

      args[n].name = XmNlabel;
      args[n].value = "OK_button_label";

 RETURN VALUE    [Toc]    [Back]
      This function returns one of the following status return constants:

      MrmSUCCESS    [Toc]    [Back]
                The function executed successfully.

      MrmPARTIAL_SUCCESS    [Toc]    [Back]
                At least one literal was successfully fetched.

      MrmBAD_HIERARCHY    [Toc]    [Back]
                The hierarchy ID was invalid.

      MrmFAILURE    [Toc]    [Back]
                The function failed.
