An application can set this resource programmatically by creating the compound string using the XmStringCreateLocalized() compound string convenience function.
This function creates a compound string in the encoding of the current locale and automatically sets the font list entry tag to XmFONTLIST_DEFAULT_TAG.
The following code segment shows one way to set the XmNlabelString resource for a push button using a program.
#include <nl_types.h> Widget button; Args args[10]; int n; XmString button_label; nl_msg my_catd; (void)XtSetLanguageProc(NULL,NULL,NULL); . . button_label = XmStringCreateLocalized (catgets(my_catd, 1, 1, "default label"), XmFONTLIST_DEFAULT_TAG); /* Create an argument list for the button */ n = 0; XtSetArg (args[n], XmNlabelString, button_label); n++; /* Create and manage the button */ button = XmCreatePushButton (toplevel, "button", args, n); XtManageChild (button); XmStringFree (button_label);
