In this JavaFX source code example, we will see how to use the JavaFX FlowPane layout with an example.

FlowPane positions nodes in a row or a column, where the nodes are wrapped when they all cannot be shown. The default orientation of a flow pane is horizontal. FlowPane has very limited usage.

JavaFX Layout FlowPane Example

In this example, we place twenty buttons in the FlowPane. The buttons are wrapped into other rows if they cannot be shown all in a single row.

package sample;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Orientation;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage stage) {

        initUI(stage);
    }

    private void initUI(Stage stage) {

        FlowPane root = new FlowPane(Orientation.HORIZONTAL, 5, 5);
        root.setPadding(new Insets(5));

        for (int i=1; i<=20; i++) {
            root.getChildren().add(new Button(String.valueOf(i)));
        }

        Scene scene = new Scene(root, 300, 250);

        stage.setTitle("FlowPane");
        stage.setScene(scene);
        stage.show();
    }

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

Output:
