In JavaFX, the HBox class is a layout container that arranges its children horizontally in a single row. The HBox layout is useful for arranging buttons, text fields, and other controls in a horizontal row.
Here's an example of how you can use the HBox layout in a JavaFX application:
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Main extends Application {
public void start(Stage stage) {
// create three buttons
Button button1 = new Button("Button 1");
Button button2 = new Button("Button 2");
Button button3 = new Button("Button 3");
// create an hbox layout
HBox hbox = new HBox();
// add the buttons to the hbox layout
hbox.getChildren().addAll(button1, button2, button3);
// set the spacing and padding of the hbox layout
hbox.setSpacing(10);
hbox.setPadding(new Insets(10, 10, 10, 10));
// create a scene and add the hbox layout to it
Scene scene = new Scene(hbox, 300, 100);
// set the title of the stage and show it
stage.setTitle("HBox Example");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}Source:www.lautturi.comThis code creates three buttons and adds them to an HBox layout. It then sets the spacing and padding of the HBox layout and adds it to a Scene. Finally, it sets the title of a Stage and displays the scene.
The HBox layout arranges the buttons in a horizontal row, with the specified spacing and padding between them. You can also use the setAlignment() method to set the alignment of the children within the HBox, and the setFillHeight() method to specify whether the children should be resized to fill the vertical space of the HBox.
