JavaFX HBox center alignment
JavaFx Layout Management: Exercise-6 with Solution
Write a JavaFX program with an HBox layout, and align its children to the center of the container.
Sample Solution:
JavaFx Code:
//Main.java
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("HBox with Center Alignment");
// Create an HBox layout with center alignment
HBox hbox = new HBox();
hbox.setSpacing(10); // Set spacing between children
// Create buttons and add them to the HBox
Button button1 = new Button("Button 1");
Button button2 = new Button("Button 2");
Button button3 = new Button("Button 3");
hbox.getChildren().addAll(button1, button2, button3);
// Set center alignment for the HBox
hbox.setAlignment(javafx.geometry.Pos.CENTER);
// Create the scene and set it in the stage
Scene scene = new Scene(hbox, 300, 200); // Width and height of the window
primaryStage.setScene(scene);
// Show the window
primaryStage.show();
}
}
In the above exercise, we create an 'HBox' layout and set the center alignment using hbox.setAlignment(javafx.geometry.Pos.CENTER). This aligns its children to the center of the container. The "setSpacing()" method is used to set the spacing between children in the 'HBox'. You can run this application to see the 'HBox' with center alignment.
Sample Output:
Flowchart:
Java Code Editor:
Previous: JavaFX VBox with custom spacing.
Next: JavaFX BorderPane different alignments.
