NAME

XmuWnInitializeNodes − initialize an array of widget nodes. 

SYNOPSIS

#include <X11/Xmu/WidgetNode.h>

void XmuWnInitializeNodes(node_array, num_nodes)
    XmuWidgeNode ∗node_array;
    int num_nodes;

Inputs

node_array
Specifies an array of widget nodes in alphabetical order.

num_nodesSpecifies the number of nodes in the array. 

AVAILABILITY

Release 5 and later. 

DESCRIPTION

XmuWnInitializeNodes() initializes an array of XmuWidgetNode.  It must be called before any of the other Xmu widget node functions.  The node_array argument is typically a statically initialized array of XmuWidgetNode (shown below) in which only the first two fields of each node are specified.  XmuWnInitializeNodes() initializes the superclass and subclass links in each XmuWidgetNode structure, and sets the resource fields to NULL.  These resource list fields are filled in by the function XmuWnFetchResources().  Note that the array of widget nodes must be in alphabetical order by the value of the label field, which needn’t be the same as the widget class name. 

USAGE

The XmuWn functions were developed for the specific needs of the viewres client, and may not be of general utility.
