Creating a Menu with I18N Resources
Problem
You want to internationalize an entire Menu .
Solution
Get the Menu 's label, and each MenuItem 's label, from a ResourceBundle .
Discussion
Fetching a single menu item is the same as fetching a button:
rb = getResourceBundle("Widgets");
try { label = rb.getString("exitMenu.label"); }
catch (MissingResourceException e) { label="Exit"; } // fallback
someMenu.add(new JMenuItem(label));
This is a lot of code, so we typically consolidate it in convenience routines (see Writing In-
ternationalization Convenience Routines ). Here is sample code, using our convenience
routines:
JMenu fm = mkMenu(rb, "file");
fm.add(mkMenuItem(rb, "file", "open"));
fm.add(mkMenuItem(rb, "file", "new"));
fm.add(mkMenuItem(rb, "file", "save"));
fm.add(mkMenuItem(rb, "file", "exit"));
mb.add(fm);
Menu um = mkMenu(rb, "edit");
um.add(mkMenuItem(rb, "edit", "copy"));
um.add(mkMenuItem(rb, "edit", "paste"));
mb.add(um);
