MrmFetchSetValues -- Fetches the values to be set from literals stored in UID files
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. MrmFetchSetVal-
ues fetches the values to be set from literals stored in UID files.
Specifies the ID of the UID hierarchy that contains the specified literal. The
value of hierarchy_id was returned in a previous call to MrmOpenHierarchyPerDis-
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 val-
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. MrmFetchSet-
Values 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_but-
ton_label in the hierarchy:
args[n].name = XmNlabel;
args[n].value = "OK_button_label";
This function returns one of the following status return constants:
The function executed successfully.
At least one literal was successfully fetched.
The hierarchy ID was invalid.
The function failed.
