A JavaFX TilePane is a layout component which lays out its child components in a grid of equally sized cells. The JavaFX TilePane layout component is represented by the class javafx.scene.layout.TilePane

Creating a TilePane

You create a JavaFX TilePane via its constructor. Here is a JavaFX TilePane instantiation example:

TilePane tilePane = new TilePane();

Adding Children to a TilePane

You can add children to a TilePane by obtaining its child collection and add adding the components to it you want the TilePane to layout. Here is an example of adding 6 buttons to a TilePane:

primaryStage.setTitle("TilePane Experiment");

Button button1 = new Button("Button 1");
Button button2 = new Button("Button Number 2");
Button button3 = new Button("Button No 3");
Button button4 = new Button("Button No 4");
Button button5 = new Button("Button 5");
Button button6 = new Button("Button Number 6");

TilePane tilePane = new TilePane();

tilePane.getChildren().add(button1);
tilePane.getChildren().add(button2);
tilePane.getChildren().add(button3);
tilePane.getChildren().add(button4);
tilePane.getChildren().add(button5);
tilePane.getChildren().add(button6);

tilePane.setTileAlignment(Pos.TOP_LEFT);

Adding a TilePane to the Scene Graph

To make a TilePane visible you must add it to the JavaFX scene graph. To do so you must add the TilePane instance to a Scene object, or add the TilePane to a layout component which is added to a Scene object.

Here is an example of adding a JavaFX TilePane to the scene graph:

package com.jenkov.javafx.layouts;

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.TilePane;
import javafx.stage.Stage;


public class TilePaneExperiments extends Application  {


    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setTitle("TilePane Experiment");

        Button button1 = new Button("Button 1");
        Button button2 = new Button("Button Number 2");
        Button button3 = new Button("Button No 3");
        Button button4 = new Button("Button No 4");
        Button button5 = new Button("Button 5");
        Button button6 = new Button("Button Number 6");

        TilePane tilePane = new TilePane();

        tilePane.getChildren().add(button1);
        tilePane.getChildren().add(button2);
        tilePane.getChildren().add(button3);
        tilePane.getChildren().add(button4);
        tilePane.getChildren().add(button5);
        tilePane.getChildren().add(button6);

        tilePane.setTileAlignment(Pos.TOP_LEFT);

        Scene scene = new Scene(tilePane, 200, 100);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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

The application resulting from this application looks like the following screen shots.

Horizontal and Vertical Spacing

You can set the horizontal and vertical spacing between the components shown inside a JavaFX TilePane using its setHGap() and setVGap() methods. Here is an example that shows how to set the horizontal and vertical gap between components in a TilePane :

tilePane.setHgap(10);
tilePane.setVgap(10);

When added to the example earlier, the resulting application would look like this:

Notice the horizontal and vertical gaps between the buttons. If there were no gaps set on the TilePane the buttons would have been positioned next to each other.
