Name

XtGetSubresources, XtGetApplicationResources − obtain subresources or application resources

Syntax

void XtGetSubresources(w, base, name, class, resources, num_resources, args, num_args)
      Widget w;
      caddr_t base;
      String name;
      String class;
      XtResourceList resources;
      Cardinal num_resources;
      ArgList args;
      Cardinal num_args;

void XtGetApplicationResources(w, base, resources, num_resources, args, num_args)
      Widget w;
      caddr_t base;
      XtResourceList resources;
      Cardinal num_resources;
      ArgList args;
      Cardinal num_args;

Arguments

argsSpecifies the argument list to override resources obtained from the resource database. 

baseSpecifies the base address of the subpart data structure where the resources should be written. 

classSpecifies the class of the subpart. 

nameSpecifies the name of the subpart. 

num_argsSpecifies the number of arguments in the argument list. 

num_resources
Specifies the number of resources in the resource list.

resourcesSpecifies the resource list for the subpart. 

wSpecifies the widget that wants resources for a subpart or that identifies the resource database to search. 

Description

The XtGetSubresources function constructs a name/class list from the application name/class, the name/classes of all its ancestors, and the widget itself. Then, it appends to this list the name/class pair passed in. The resources are fetched from the argument list, the resource database, or the default values in the resource list. Then, they are copied into the subpart record. If args is NULL, num_args must be zero. However, if num_args is zero, the argument list is not referenced.

The XtGetApplicationResources function first uses the passed widget, which is usually an application shell, to construct a resource name and class list, Then, it retrieves the resources from the argument list, the resource database, or the resource list default values. After adding base to each address, XtGetApplicationResources copies the resources into the address given in the resource list. If args is NULL, num_args must be zero. However, if num_args is zero, the argument list is not referenced. The portable way to specify application resources is to declare them as members of a structure and pass the address of the structure as the base argument.
