How to create a border pane using JavaFX?

JavaFXObject Oriented ProgrammingProgramming

Once you create all the required nodes for your application you can arrange them using a layout. Where a layout is a process of calculating the position of objects in the given space. JavaFX provides various layouts in the javafx.scene.layout package.

Border Pane

In this layout, the nodes are arranged in the top, center, bottom, left, and, right positions. You can create a border pane in your application by instantiating the javafx.scene.layout.BorderPane class.

There are five properties of this class (Node type) specifying the positions in the pane, namely, top, bottom, right, left, center. You can set nodes as values to these properties using the setTop(), setBottom(), setRight(), setleft() and, setCenter().

You can set the size of the border pane using the setPrefSize() method. To add nodes to this pane you can either pass them as arguments of the constructor or, add them to the observable list of the pane as −

getChildren().addAll();

Example

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class BorderPaneExample extends Application {
   public void start(Stage stage) {
      //Creating buttons
      Button left = new Button("Left");
      left.setPrefSize(200, 100);
      Button right = new Button("Right");
      right.setPrefSize(200, 100);
      Button top = new Button("Top");
      top.setPrefSize(595, 100);
      Button bottom = new Button("Buttom");
      bottom.setPrefSize(595, 100);
      Button center = new Button("Center");
      center.setPrefSize(200, 100);
      //Creating the border pane
      BorderPane pane = new BorderPane();
      //Setting the top, bottom, center, right and left nodes to the pane
      pane.setTop(top);
      pane.setBottom(bottom);
      pane.setLeft(left);
      pane.setRight(right);
      pane.setCenter(center);
      //Setting the Scene
      Scene scene = new Scene(pane, 595, 300);
      stage.setTitle("Border Pane");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
