Toggle Menu Items in JavaFX

JavaFX supports three kinds of menu items namely − check menu item, custom menu item, and, radio menu item.

A RadioMenuItem is a special MenuItem that has a checkmark (tick) similar to a checkbox. This has two states selected (with a checkmark) and unselected (without checkmark). It is represented by the javafx.scene.control.RadioMenuItem class.

You can add a bunch of radio-menu-items to a toggle group just like a toggle button or a radio button.

Example

Following JavaFX example demonstrates the creation of a toggled group of radio-menu-items

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.scene.control.RadioMenuItem;
import javafx.scene.control.SeparatorMenuItem;
import javafx.scene.control.ToggleGroup;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class RadioMenuItem_Toggle extends Application {
   @Override
   public void start(Stage stage) {
      //Creating a menu
      Menu fileMenu = new Menu("File");
      //Creating menu Items
      Menu view = new Menu("Align");
      MenuItem edit = new MenuItem("Edit");
      MenuItem exit = new MenuItem("Exit");
      //Creating menu items for the sub item edit
      RadioMenuItem sub1 = new RadioMenuItem("Right");
      RadioMenuItem sub2 = new RadioMenuItem("Left");
      RadioMenuItem sub3 = new RadioMenuItem("Center");
      //Adding the Sub menu items to a toggle group
      ToggleGroup group = new ToggleGroup();
      sub1.setToggleGroup(group);
      sub2.setToggleGroup(group);
      sub3.setToggleGroup(group);
      //Adding toggle group to the view menu item
      view.getItems().addAll(sub1, sub2, sub3);
      //Creating a separator
      SeparatorMenuItem sep = new SeparatorMenuItem();
      //Adding all the menu items to the menu
      fileMenu.getItems().addAll(edit, view, sep, exit);
      //Creating a menu bar and adding menu to it.
      MenuBar menuBar = new MenuBar(fileMenu);
      menuBar.setTranslateX(200);
      menuBar.setTranslateY(20);
      //Setting the stage
      Group root = new Group(menuBar);
      Scene scene = new Scene(root, 595, 200, Color.BEIGE);
      stage.setTitle("Menu Example");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
