DwtFetchSetValues(3Dwt) DwtFetchSetValues(3Dwt)
Name
DwtFetchSetValues - Fetches the values to be set from literals stored in UID files.
Syntax
#include <X11/DwtAppl.h>
Cardinal DwtFetchSetValues(hierarchy_id, widget, args, num_args)
DRMHierarchy hierarchy_id;
Widget widget;
ArgList args;
Cardinal num_args;
Arguments
hierarchy_id
Specifies the ID of the UID hierarchy that contains the specified literal. The hierarchy_id was returned in a previous call to
DwtOpenHierarchy.
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 DwtN followed
by the name that uniquely identifies this attribute tag. For example, DwtNwidth 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.
Description
The DwtFetchSetValues 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. DwtFetchSetValues fetches the values to be set from literals stored in UID files.
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. DwtFetchSetValues allows a widget to be modified after creation using UID file
values exactly as is done for creation values in DwtFetchWidget.
As in DwtFetchWidget, 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
DwtN. 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 = DwtNlabel;
args[n].value = "OK_button_label";
Return Values
This function returns one of these status return constants:
DRMSuccess The function executed
successfully.
DRMFailure The function failed.
