Question

我正在制作闹钟类程序，我需要一种方法让时钟面对特定的字体。我曾多次尝试过多次。如果不可能，请提供另一种解决方案吗？提前谢谢！

public class Menu extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {

    //Frame stuff (works)
    GridPane grid = new GridPane();
    grid.setAlignment(Pos.CENTER);
    grid.setHgap(10);
    grid.setVgap(10);

    //Frame Size
    Scene scene = new Scene(new DigitalClock(),1080, 720);

    //Icon
    primaryStage.getIcons().add(new Image(getClass().getResourceAsStream(("/lib/logo.png"))));
    primaryStage.setTitle("Clock: 140 Edition");

    //Necessities
    primaryStage.setScene(scene);
    primaryStage.show();
}

public static void main(String args[]) {
    launch(args);
}

}

class Util {
    public static String pad(int fieldWidth, char padChar, String s) {
        StringBuilder sb = new StringBuilder();
        for (int i = s.length(); i < fieldWidth; i++) {
          sb.append(padChar);
        }
        sb.append(s);

        return sb.toString();
        }
}

class DigitalClock extends Label {

    public DigitalClock() {
        bindToTime();
        }

    // the digital clock updates once a second.
    private void bindToTime() {
    Timeline timeline = new Timeline(
      new KeyFrame(Duration.seconds(0),
        new EventHandler<ActionEvent>() {
          @Override public void handle(ActionEvent actionEvent) {
            Calendar time = Calendar.getInstance();
            String hourString = Util.pad(2, ' ', time.get(Calendar.HOUR) == 0 ? "12" : time.get(Calendar.HOUR) + "");
            String minuteString = Util.pad(2, '0', time.get(Calendar.MINUTE) + "");
            String secondString = Util.pad(2, '0', time.get(Calendar.SECOND) + "");
            String ampmString = time.get(Calendar.AM_PM) == Calendar.AM ? "AM" : "PM";
            setText(hourString + ":" + minuteString + ":" + secondString + " " + ampmString);
          }
        }
      ),
      new KeyFrame(Duration.seconds(1))
    );
    timeline.setCycleCount(Animation.INDEFINITE);
    timeline.play();
    }

我也知道有些导入没有使用，我宁愿保留它们。再次感谢！

Font与您在示例中使用的Label有关。

必须读：http://www.guigarage.com/2014/10/integrate-custom-fonts-javafx-application-using-css/

＆lt; -----------------做的方法-----------------＆gt;

1）使用外部css ：

/*The font path*/
@font-face{
    src: url("../fonts/Younger than me Bold.ttf");
}

/* An element which has this id*/
#LabelID{
 -fx-font-family:"Younger than me";
 -fx-font-size:18.0;
}

//or for all labels
.label{
  -fx-font-family:"Younger than me";
  -fx-font-size:18.0;
}

2）使用 setStyle（...）：

`label.setStyle("-fx-font-family:monospace; -fx-font-size:16px; -fx-text-fill:black; -fx-border-color:red;");`

3）使用 setFont（...）：

b.setFont(new Font("Arial", 24));

4）棘手且不推荐（不包含在JavaFX文档中）：here
