Menu items:
| MenuItem |
 |
| CheckMenuItem |
 |
| RadioMenuItem |
 |
| SeparatorMenuItem |  |
Here is a simple example, create a MenuBar with Menus and MenuItems.
MenuDemo.java
package org.o7planning.javafx.menu;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class MenuDemo extends Application {
@Override
public void start(Stage stage) {
// Create MenuBar
MenuBar menuBar = new MenuBar();
// Create menus
Menu fileMenu = new Menu("File");
Menu editMenu = new Menu("Edit");
Menu helpMenu = new Menu("Help");
// Create MenuItems
MenuItem newItem = new MenuItem("New");
MenuItem openFileItem = new MenuItem("Open File");
MenuItem exitItem = new MenuItem("Exit");
MenuItem copyItem = new MenuItem("Copy");
MenuItem pasteItem = new MenuItem("Paste");
// Add menuItems to the Menus
fileMenu.getItems().addAll(newItem, openFileItem, exitItem);
editMenu.getItems().addAll(copyItem, pasteItem);
// Add Menus to the MenuBar
menuBar.getMenus().addAll(fileMenu, editMenu, helpMenu);
BorderPane root = new BorderPane();
root.setTop(menuBar);
Scene scene = new Scene(root, 350, 200);
stage.setTitle("JavaFX Menu (o7planning.org)");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}
Similarly a Button, you can create a MenuItem with text and Image. A menu can contain MenuItem, CheckMenuItem, RadioMenuItem or SeparatorMenuItem to separate the items.
MenuDemo2.java
package org.o7planning.javafx.menu;
import org.o7planning.javafx.utils.MyImageUtils;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.CheckMenuItem;
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.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class MenuDemo2 extends Application {
@Override
public void start(Stage stage) {
// Create MenuBar
MenuBar menuBar = new MenuBar();
// Create menus
Menu fileMenu = new Menu("File");
Menu editMenu = new Menu("Edit");
Menu projectMenu = new Menu("Project");
Menu helpMenu = new Menu("Help");
// Create MenuItems
MenuItem newItem = new MenuItem("New");
Image newImage = MyImageUtils.getImage("/org/o7planning/javafx/icon/new-16.png");
newItem.setGraphic(new ImageView(newImage));
MenuItem openFileItem = new MenuItem("Open File");
// SeparatorMenuItem.
SeparatorMenuItem separator= new SeparatorMenuItem();
MenuItem exitItem = new MenuItem("Exit");
MenuItem copyItem = new MenuItem("Copy");
MenuItem pasteItem = new MenuItem("Paste");
// CheckMenuItem
CheckMenuItem buildItem = new CheckMenuItem("Build Automatically");
Image buildImage = MyImageUtils.getImage("/org/o7planning/javafx/icon/build-16.png");
buildItem.setGraphic(new ImageView(buildImage));
buildItem.setSelected(true);
// RadioMenuItem
RadioMenuItem updateItem1 = new RadioMenuItem("Auto Update");
RadioMenuItem updateItem2 = new RadioMenuItem("Ask for Update");
ToggleGroup group = new ToggleGroup();
updateItem1.setToggleGroup(group);
updateItem2.setToggleGroup(group);
updateItem1.setSelected(true);
// Add menuItems to the Menus
fileMenu.getItems().addAll(newItem, openFileItem,separator, exitItem);
editMenu.getItems().addAll(copyItem, pasteItem);
projectMenu.getItems().add(buildItem);
helpMenu.getItems().addAll(updateItem1,updateItem2);
// Add Menus to the MenuBar
menuBar.getMenus().addAll(fileMenu, editMenu, projectMenu, helpMenu);
BorderPane root = new BorderPane();
root.setTop(menuBar);
Scene scene = new Scene(root, 350, 200);
stage.setTitle("JavaFX Menu (o7planning.org)");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}
MyImageUtils.java
package org.o7planning.javafx.utils;
import java.io.InputStream;
import javafx.scene.image.Image;
public class MyImageUtils {
// sourcePath: /org/o7planning/javafx/icon/java-16.png
public static Image getImage(String sourcePath) {
InputStream input = null;
try {
Class<?> c = MyImageUtils.class;
input = c.getResourceAsStream(sourcePath);
Image img = new Image(input);
return img;
} finally {
closeQuietly(input);
}
}
private static void closeQuietly(InputStream is) {
try {
if (is != null) {
is.close();
}
} catch (Exception e) {
}
}
}
With Menu Item, you can handle the event when the user clicks on it and set the accelerator for MenuItem. The example below put shortcuts Ctrl + X to "Exit" item. Users can press Ctrl + X to exit the application.
// Set Accelerator for Exit MenuItem.
exitItem.setAccelerator(KeyCombination.keyCombination("Ctrl+X"));
// When user click on the Exit item.
exitItem.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
System.exit(0);
}
});

MenuEventDemo.java
package org.o7planning.javafx.menu;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.scene.input.KeyCombination;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class MenuEventDemo extends Application {
@Override
public void start(Stage stage) {
// Create MenuBar
MenuBar menuBar = new MenuBar();
// Create menus
Menu fileMenu = new Menu("File");
Menu editMenu = new Menu("Edit");
Menu helpMenu = new Menu("Help");
// Create MenuItems
MenuItem newItem = new MenuItem("New");
MenuItem openFileItem = new MenuItem("Open File");
MenuItem exitItem = new MenuItem("Exit");
// Set Accelerator for Exit MenuItem.
exitItem.setAccelerator(KeyCombination.keyCombination("Ctrl+X"));
// When user click on the Exit item.
exitItem.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
System.exit(0);
}
});
// Add menuItems to the Menus
fileMenu.getItems().addAll(newItem, openFileItem, exitItem);
// Add Menus to the MenuBar
menuBar.getMenus().addAll(fileMenu, editMenu, helpMenu);
BorderPane root = new BorderPane();
root.setTop(menuBar);
Scene scene = new Scene(root, 350, 200);
stage.setTitle("JavaFX Menu (o7planning.org)");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}
