How to create a scroll pane using JavaFX?
A scroll pane holds a UI element and provides a scrollable view of it. In JavaFX, you can create a scroll pane by instantiating the javafx.scene.control.ScrollPane class. You can set content to the scroll pane using the setContent() method.
To add a scroll pane to a node −
Instantiate the ScrollPane class.
Create the desired node.
Set the node to the scroll pane using the setContent() method.
Set the dimensions of the scroll pane using the setter methods.
Add the scroll pane to the layout pane or group.
Example
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class ScrollPaneActionExample extends Application {
public void start(Stage stage) throws FileNotFoundException {
//creating the image object
InputStream stream = new FileInputStream("D:\\images\\elephant.jpg");
Image image = new Image(stream);
//Creating the image view
ImageView imageView = new ImageView();
//Setting image to the image view
imageView.setImage(image);
//Setting the image view parameters
imageView.setX(5);
imageView.setY(0);
imageView.setFitWidth(595);
imageView.setPreserveRatio(true);
//Creating the scroll pane
ScrollPane scroll = new ScrollPane();
scroll.setPrefSize(595, 200);
//Setting content to the scroll pane
scroll.setContent(imageView);
//Setting the stage
Group root = new Group();
root.getChildren().addAll(scroll);
Scene scene = new Scene(root, 595, 200, Color.BEIGE);
stage.setTitle("Scroll Pane Example");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}Output
