我有javafx应用程序显示一些信息。
我是javafx的新手，在尝试进行一些测试时试图理解它。
我想在应用程序之上添加时钟，我找到next source
如何在同一屏幕（屏幕顶部）上将此时钟（从源）添加到当前应用程序？我的应用程序使用main.java上的下一个代码（我也使用FXML文件并通过“场景”构建器进行编辑）：
package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.stage.Stage;
import net.sourceforge.zmanim.hebrewcalendar.JewishCalendar;
import net.sourceforge.zmanim.hebrewcalendar.HebrewDateFormatter;
import net.sourceforge.zmanim.hebrewcalendar.JewishCalendar;
import net.sourceforge.zmanim.util.GeoLocation;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
Label lblShabat = (Label) root.lookup("#shabat");
Label lbldateHeb = (Label) root.lookup("#dateHeb");
JewishCalendar israelCalendar = new JewishCalendar();
israelCalendar.setInIsrael(true); //set the calendar to Israel
JewishCalendar chutsLaaretzCalendar = new JewishCalendar();
chutsLaaretzCalendar.setInIsrael(false); //not really needed since the API defaults to false
JewishCalendar jd = new JewishCalendar();
HebrewDateFormatter hdf = new HebrewDateFormatter();
hdf.setHebrewFormat(true);
for(int i = 0; i < 14; i++){
israelCalendar.forward(); //roll the date forward a day
// chutsLaaretzCalendar.forward(); //roll the date forward a day
if(israelCalendar.getDayOfWeek() == 7){ //ignore weekdays
if (lblShabat!=null) lblShabat.setText(hdf.formatYomTov(jd)); //hdf.formatParsha(israelCalendar)
//hdf.formatYomTov(jd)
}
}
String cholHamoedSuccos = "חול המועד סוכות";
if(hdf.formatYomTov(jd) == cholHamoedSuccos) {
String image = Main.class.getResource("Dollarphotoclub_91486993.jpg").toExternalForm();
root.setStyle("-fx-background-image: url('" + image + "'); " +
"-fx-background-position: center center; " +
"-fx-background-repeat: stretch;");
}
if (lbldateHeb!=null) lbldateHeb.setText(hdf.format(jd));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.setFullScreen(true);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
答案 0 :(得分：1)
TheStageOfthesource.getScene().getRoot();//will give you the root pane
就是你想要的？然后将其添加到Pane

也许有一种更好的方法不需要那么多的重构，但我重构了Clock，所以函数createLayout（）与Clock的start（）函数分开。在SceneBuilder中添加一个子场景，您可以在其中放置时钟并为其设置ID，我使用了node file.js --data { "name": "Dave" }。在控制器中，initialize（）函数创建布局并将clocksubscene的根设置为布局。还将clock.css添加到主场景的样式中。
Refactored Clock.java（省略的部分未更改）：
clocksubscene新的Controller初始化代码：
public void start(final Stage stage) throws Exception {
Parent layout = createLayout();
final Scene scene = new Scene(layout, Color.TRANSPARENT);
scene.getStylesheets().add(getResource("clock.css"));
// show the scene.
stage.initStyle(StageStyle.TRANSPARENT);
stage.setScene(scene);
stage.show();
}
public Parent createLayout() {
// construct the analogueClock pieces.
final Circle face = new Circle(100, 100, 100);
face.setId("face");
final Label brand = new Label("Splotch");
brand.setId("brand");
brand.layoutXProperty().bind(face.centerXProperty().subtract(brand.widthProperty().divide(2)));
brand.layoutYProperty().bind(face.centerYProperty().add(face.radiusProperty().divide(2)));
final Line hourHand = new Line(0, 0, 0, -50);
hourHand.setTranslateX(100);
hourHand.setTranslateY(100);
hourHand.setId("hourHand");
final Line minuteHand = new Line(0, 0, 0, -75);
minuteHand.setTranslateX(100);
minuteHand.setTranslateY(100);
minuteHand.setId("minuteHand");
final Line secondHand = new Line(0, 15, 0, -88);
secondHand.setTranslateX(100);
secondHand.setTranslateY(100);
secondHand.setId("secondHand");
final Circle spindle = new Circle(100, 100, 5);
spindle.setId("spindle");
Group ticks = new Group();
for (int i = 0; i < 12; i++) {
Line tick = new Line(0, -83, 0, -93);
tick.setTranslateX(100);
tick.setTranslateY(100);
tick.getStyleClass().add("tick");
tick.getTransforms().add(new Rotate(i * (360 / 12)));
ticks.getChildren().add(tick);
}
final Group analogueClock = new Group(face, brand, ticks, spindle, hourHand, minuteHand, secondHand);
// construct the digitalClock pieces.
final Label digitalClock = new Label();
digitalClock.setId("digitalClock");
// determine the starting time.
Calendar calendar = GregorianCalendar.getInstance();
final double seedSecondDegrees = calendar.get(Calendar.SECOND) * (360 / 60);
final double seedMinuteDegrees = (calendar.get(Calendar.MINUTE) + seedSecondDegrees / 360.0) * (360 / 60);
final double seedHourDegrees = (calendar.get(Calendar.HOUR) + seedMinuteDegrees / 360.0) * (360 / 12);
// define rotations to map the analogueClock to the current time.
final Rotate hourRotate = new Rotate(seedHourDegrees);
final Rotate minuteRotate = new Rotate(seedMinuteDegrees);
final Rotate secondRotate = new Rotate(seedSecondDegrees);
hourHand.getTransforms().add(hourRotate);
minuteHand.getTransforms().add(minuteRotate);
secondHand.getTransforms().add(secondRotate);
// the hour hand rotates twice a day.
final Timeline hourTime = new Timeline(
new KeyFrame(
Duration.hours(12),
new KeyValue(
hourRotate.angleProperty(),
360 + seedHourDegrees,
Interpolator.LINEAR
)
)
);
// the minute hand rotates once an hour.
final Timeline minuteTime = new Timeline(
new KeyFrame(
Duration.minutes(60),
new KeyValue(
minuteRotate.angleProperty(),
360 + seedMinuteDegrees,
Interpolator.LINEAR
)
)
);
// move second hand rotates once a minute.
final Timeline secondTime = new Timeline(
new KeyFrame(
Duration.seconds(60),
new KeyValue(
secondRotate.angleProperty(),
360 + seedSecondDegrees,
Interpolator.LINEAR
)
)
);
// the digital clock updates once a second.
final Timeline digitalTime = new Timeline(
new KeyFrame(Duration.seconds(0),
new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent actionEvent) {
Calendar calendar = GregorianCalendar.getInstance();
String hourString = pad(2, '0', calendar.get(Calendar.HOUR) == 0 ? "12" : calendar.get(Calendar.HOUR) + "");
String minuteString = pad(2, '0', calendar.get(Calendar.MINUTE) + "");
String secondString = pad(2, '0', calendar.get(Calendar.SECOND) + "");
String ampmString = calendar.get(Calendar.AM_PM) == Calendar.AM ? "AM" : "PM";
digitalClock.setText(hourString + ":" + minuteString + ":" + secondString + " " + ampmString);
}
}
),
new KeyFrame(Duration.seconds(1))
);
// time never ends.
hourTime.setCycleCount(Animation.INDEFINITE);
minuteTime.setCycleCount(Animation.INDEFINITE);
secondTime.setCycleCount(Animation.INDEFINITE);
digitalTime.setCycleCount(Animation.INDEFINITE);
// start the analogueClock.
digitalTime.play();
secondTime.play();
minuteTime.play();
hourTime.play();
// add a glow effect whenever the mouse is positioned over the clock.
final Glow glow = new Glow();
analogueClock.setOnMouseEntered(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent mouseEvent) {
analogueClock.setEffect(glow);
}
});
analogueClock.setOnMouseExited(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent mouseEvent) {
analogueClock.setEffect(null);
}
});
// layout the scene.
final VBox layout = new VBox();
layout.getChildren().addAll(analogueClock, digitalClock);
layout.setAlignment(Pos.CENTER);
return layout;
}
在主开始例行程序中：
@Override
public void initialize(URL url, ResourceBundle rb) {
Clock clock = new Clock();
clocksubscene.setRoot(clock.createLayout());
}
