Class MenuBar

  • All Implemented Interfaces:
    Styleable, EventTarget, Skinnable
    @DefaultProperty("menus")
public class MenuBar
extends Control

    A MenuBar control traditionally is placed at the very top of the user interface, and embedded within it are Menus. To add a menu to a menubar, you add it to the menus ObservableList. By default, for each menu added to the menubar, it will be represented as a button with the Menu text value displayed.

    MenuBar sets focusTraversable to false.

    To create and populate a MenuBar, you may do what is shown below. Please refer to the Menu API page for more information on how to configure it. 
    
 final Menu menu1 = new Menu("File");
 final Menu menu2 = new Menu("Options");
 final Menu menu3 = new Menu("Help");

 MenuBar menuBar = new MenuBar();
 menuBar.getMenus().addAll(menu1, menu2, menu3);

      • useSystemMenuBar

        public final BooleanProperty useSystemMenuBarProperty
        Use the system menu bar if the current platform supports it. This should not be set on more than one MenuBar instance per Stage. If this property is set to true on more than one MenuBar in the same Stage, then the last menu set is allowed to modify the system menu bar, and if there is an existing installed system menu it is unset and removed from the system menu bar. Note that trying to uni-directionally bind to this property will throw a RuntimeException. Please use bi-directional binding to this property instead.
