JavaFX FlowPane

FlowPane layout pane organizes the nodes in a flow that are wrapped at the flowpane's boundary. The horizontal flowpane arranges the nodes in a row and wrap them according to the flowpane's width. The vertical flowpane arranges the nodes in a column and wrap them according to the flowpane's height. FlowPane layout is represented by javafx.scene.layout.FlowPane class. We just need to instantiate this class to create the flowpane layout.

Property

There are various properties of the class which are described in the table below.

Property	Description	Setter Methods
alignment	The overall alignment of the flowpane's content.	setAlignment(Pos value)
columnHalignment	The horizontal alignment of nodes within the columns.	setColumnHalignment(HPos Value)
hgap	Horizontal gap between the columns.	setHgap(Double value)
orientation	Orientation of the flowpane	setOrientation(Orientation value)
prefWrapLength	The preferred height or width where content should wrap in the horizontal or vertical flowpane.	setPrefWrapLength(double value)
rowValignment	The vertical alignment of the nodes within the rows.	setRowValignment(VPos value)
vgap	The vertical gap among the rows	setVgap(Double value)

Constructors

There are 8 constructors in the class that are given below.

FlowPane()
FlowPane(Double Hgap, Double Vgap)
FlowPane(Double Hgap, Double Vgap, Node? children)
FlowPane(Node... Children)
FlowPane(Orientation orientation)
FlowPane(Orientation orientation, double Hgap, Double Vgap)
FlowPane(Orientation orientation, double Hgap, Double Vgap, Node? children )
FlowPane(Orientation orientation, Node... Children)

Example

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;

public class FlowPaneTest extends Application {

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("FlowPane Example");
        FlowPane root = new FlowPane();
        root.setVgap(6);
        root.setHgap(5);
        root.setPrefWrapLength(250);
        root.getChildren().add(new Button("Start"));
        root.getChildren().add(new Button("Stop"));
        root.getChildren().add(new Button("Reset"));
        Scene scene = new Scene(root,300,200);
 
        primaryStage.setScene(scene);
        primaryStage.show();
    }
 
    public static void main(String[] args) {
        launch(args);
    }
}
