JavaFX: Setting Constraints On Children

This entry is part 8 of 55 in the series JavaFX

In the previous example, we have the label and text overlapping each other.  Stackpane provides a static method to set positioning constraint on its children.

Let’s apply this constraint to the label.

In this example, we set the label to the TOP_CENTER position of the stackpane.

Notice how I have also set the color of the label.

package javafxapplication8;
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.stage.Stage;
public class JavaFXApplication8 extends Application {
    public void start(Stage primaryStage) {
        primaryStage.setTitle("JavaFX Program");
        StackPane stackpane = new StackPane();
        Scene scene = new Scene(stackpane, 300, 250);
        Label lb = new Label();
        lb.setFont(Font.font("Times New Roman", 24));
        lb.setText("Hello World");
        StackPane.setAlignment(lb, Pos.TOP_CENTER);
    public static void main(String[] args) {
