Q23.java

package Test.Q36;
//importing required file and classes
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Slider;
import javafx.scene.layout.Pane;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;



public class Q23 extends Application {

//    slider object
    Slider slider;
//    rect object
    Rectangle rect;
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) {

        // creating new scene object with createPane , width and height
        Scene scene = new Scene(createPane(),430,150);
//        setting scene to the stage
        stage.setScene(scene);
//        showing the stage
        stage.show();
    }

    public Pane createPane()
    {
//        creating new rect with x, y, width , height
        rect = new Rectangle(20,20,100,100);
//        creating new pane object
        Pane pane = new Pane(rect);

//        creating new slider with min, max value
        slider = new Slider(0,300,20);
//        adding slider to the pane
        pane.getChildren().add(slider);

//        listening to change property of slider then applying new value to rect.setX
        slider.valueProperty().addListener((observable, oldValue, newValue) -> {

//            setting rect.setX
            rect.setX(Double.parseDouble(Double.toString(newValue.intValue())));

        });
//        return pane
        return pane;
    }
