# Class MenuItem

java.lang.Object
javafx.scene.control.MenuItem

All Implemented Interfaces:
  `Styleable`, `EventTarget`

Direct Known Subclasses:
  `CheckMenuItem`, `CustomMenuItem`, `Menu`, `RadioMenuItem`

@IDProperty("id") public class MenuItem extends Object implements EventTarget, Styleable

MenuItem is intended to be used in conjunction with `Menu` to provide options to users. MenuItem serves as the base class for the bulk of JavaFX menus API. It has a display `text` property, as well as an optional `graphic` node that can be set on it. The `accelerator` property enables accessing the associated action in one keystroke. Also, as with the `Button` control, by using the `setOnAction(javafx.event.EventHandler<javafx.event.ActionEvent>)` method, you can have an instance of MenuItem perform any action you wish.

Note: Whilst any size of graphic can be inserted into a MenuItem, the most commonly used size in most applications is 16x16 pixels. This is the recommended graphic dimension to use if you're using the default style provided by JavaFX.

To create a MenuItem is simple:

    MenuItem menuItem = new MenuItem("Open");
    menuItem.setOnAction(e -> System.out.println("Opening Database Connection..."));
    Circle graphic = new Circle(8);
    graphic.setFill(Color.GREEN);
    menuItem.setGraphic(graphic);

    Menu menu = new Menu("File");
    menu.getItems().add(menuItem);
    MenuBar menuBar = new MenuBar(menu);

  JavaFX 2.0

  - ### fire

    public void fire()

  - ### buildEventDispatchChain

    public EventDispatchChain buildEventDispatchChain(EventDispatchChain tail)
    Description copied from interface: `EventTarget`
    Construct an event dispatch chain for this target. The event dispatch chain contains event dispatchers which might be interested in processing of events targeted at this `EventTarget`. This event target is not automatically added to the chain, so if it wants to process events, it needs to add an `EventDispatcher` for itself to the chain.

    In the case the event target is part of some hierarchy, the chain for it is usually built from event dispatchers collected from the root of the hierarchy to the event target.

    The event dispatch chain is constructed by modifications to the provided initial event dispatch chain. The returned chain should have the initial chain at its end so the dispatchers should be prepended to the initial chain.

    The caller shouldn't assume that the initial chain remains unchanged nor that the returned value will reference a different chain.

    Specified by:
      `buildEventDispatchChain` in interface `EventTarget`
    Parameters:
      `tail` - the initial chain to build from
    Returns:
      the resulting event dispatch chain for this target
