JavaFX example to set slider to the progress bar

JavaFXObject Oriented ProgrammingProgramming

ProgressBar − A progress bar is an indicator of the advancement of an event (a series of steps). You can create a progress bar by instantiating the javafx.scene.control.ProgressBar class.

Slider − JavaFX provides a class known as Slider, this represents a slider component that displays a continuous range of values. This contains a track on which the numerical values are displayed. Along the track, there is a thumb pointing to the numbers. You can provide the maximum, minimum, and initial values of the slider.

Example

In the following example, we are setting the slider to the ProgressBar.

import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.geometry.Insets;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.ProgressBar;
import javafx.scene.control.ProgressIndicator;
import javafx.scene.control.Slider;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class ProgressBar_Slider extends Application {
   public void start(Stage stage) {
      //Creating a progress bar
      ProgressBar progress = new ProgressBar(0.1);
      //Creating a progress indicator
      ProgressIndicator indicator = new ProgressIndicator(0.1);
      //Setting the size of the progress bar
      progress.setPrefSize(200, 30);
      //Creating a slider
      Slider slider= new Slider(0, 1, 0);
      slider.setShowTickLabels(true);
      slider.setShowTickMarks(true);
      slider.setMajorTickUnit(0.1);
      slider.setBlockIncrement(0.1);
      slider.valueProperty().addListener(new ChangeListener<Number>() {
         public void changed(ObservableValue <?extends Number>observable, Number
         oldValue, Number newValue){
            //Setting the angle for the rotation
            progress.setProgress((double) newValue);
            //Setting value to the indicator
            indicator.setProgress((double) newValue);
         }
      });
      //Creating a hbox to hold the progress bar and progress indicator
      HBox hbox = new HBox(50);
      hbox.setPadding(new Insets(75, 150, 50, 60));
      hbox.getChildren().addAll(slider, progress, indicator);
      //Setting the stage
      Group root = new Group(hbox);
      Scene scene = new Scene(root, 595, 200, Color.BEIGE);
      stage.setTitle("Progress Bar");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
