Java Swing查看字体和设置全局字体

查看支持的字体

以下代码用于运行时在控制台打印支持的字体

GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
final String AvailableFontFamilyNames[] = gEnv.getAvailableFontFamilyNames();
Stream.of(AvailableFontFamilyNames).forEach(System.out::println);

设置全局字体

private void initGlobalFont(Font font) {
  FontUIResource fontRes = new FontUIResource(font);
    for (Enumeration<Object> keys = UIManager.getDefaults().keys(); keys.hasMoreElements(); ) {
      Object key = keys.nextElement();
      Object value = UIManager.get(key);
      if (value instanceof FontUIResource) {
        UIManager.put(key, fontRes);
      }
   }
}
