DESCRIPTION

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. 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

This function returns one of the following status return constants:

MrmSUCCESS

The function executed successfully.

MrmPARTIAL_SUCCESS

At least one literal was successfully fetched.

MrmBAD_HIERARCHY

The hierarchy ID was invalid.

MrmFAILURE

The function failed.
