Design FlowPane on Scene Builder

1. FlowPane Layout

FlowPane is a container. It arranges the consecutive subcomponents on a row, and automatically pushes the subcomponents down to next line if the current row is filled up.

2. FlowPane example

FlowPaneDemo.java

package org.o7planning.javafx.flowpane;

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.CheckBox;
import javafx.scene.control.RadioButton;
import javafx.scene.control.TextField;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;

public class FlowPaneDemo extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        FlowPane root = new FlowPane();
       
        root.setHgap(10);
        root.setVgap(20);
        root.setPadding(new Insets(15,15,15,15));
       
        // Button 1
        Button button1= new Button("Button1");
        root.getChildren().add(button1);
       
       
        // Button 2
        Button button2 = new Button("Button2");
        button2.setPrefSize(100, 100);
        root.getChildren().add(button2);
       
        // TextField
        TextField textField = new TextField("Text Field");
        textField.setPrefWidth(110);
         
       
        root.getChildren().add(textField);
       
        // CheckBox
        CheckBox checkBox = new CheckBox("Check Box");
         
        root.getChildren().add(checkBox);
       
        // RadioButton
        RadioButton radioButton = new RadioButton("Radio Button");
        root.getChildren().add(radioButton);
       
        Scene scene = new Scene(root, 550, 250);

        primaryStage.setTitle("FlowPane Layout Demo");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

   
    public static void main(String[] args) {
        launch(args);
    }
   
}

3. Design FlowPane on Scene Builder

It is easy for you to design the interface by using JavaFX Scane Builder. This below illustration shows the FlowPane design with Scane Builder.
