How to add accelerators to a menu item?

A menu is a list of options or commands presented to the user, typically menus contains items that perform some action. The contents of a menu are known as menu items and a menu bar holds multiple menus.

In JavaFX a menu is represented by the javafx.scene.control.Menu class, a menu item is represented by the javafx.scene.control.MenuItem class, And, the javafx.scene.control.MenuBar class represents a menu bar.

Adding accelerators to a menu item −

Accelerators are short cuts to menu Items. The MenuItem class contains a property named accelerator (of type KeyCombination), which associates a combination to the action of the current MenuItem.

You can set value to this property using the setAccelerator() method. Therefore, to set accelerator to a particular MenuItem, invoke the setAccelerator() method on it as shown below −

MenuItem item = new MenuItem("Exit", imgView3); item.setAccelerator(KeyCombination.keyCombination("Ctrl+X"));

Example

import javafx.application.Application; import javafx.event.ActionEvent; 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.image.ImageView; import javafx.scene.input.KeyCombination; import javafx.scene.paint.Color; import javafx.stage.Stage; public class MenuItemAccelerators extends Application {    @Override    public void start(Stage stage) {       //Creating image view files       ImageView imgView1 = new ImageView("UIControls/open.png");       imgView1.setFitWidth(20);       imgView1.setFitHeight(20);       ImageView imgView2 = new ImageView("UIControls/Save.png");       imgView2.setFitWidth(20);       imgView2.setFitHeight(20);       ImageView imgView3 = new ImageView("UIControls/Exit.png");       imgView3.setFitWidth(20);       imgView3.setFitHeight(20);       //Creating menu       Menu fileMenu = new Menu("File");       //Creating menu Items       MenuItem item1 = new MenuItem("Open File", imgView1);       MenuItem item2 = new MenuItem("Save file", imgView2);       MenuItem item3 = new MenuItem("Exit", imgView3);       //Setting accelerators to the menu items       item1.setAccelerator(KeyCombination.keyCombination("Ctrl+F"));       item2.setAccelerator(KeyCombination.keyCombination("Ctrl+S"));       item3.setAccelerator(KeyCombination.keyCombination("Ctrl+X"));       //Adding all the menu items to the menu       fileMenu.getItems().addAll(item1, item2, item3);       //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);    } }
