Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The NativeMenuItem class represents a single item in a menu.

A menu item can be a command, a submenu, or a separator line:

  • To create a command item, call the NativeMenuItem constructor, passing in a string for the label and false for the isSeparator parameter.
  • To create a submenu, create a command item for the parent menu and assign the NativeMenu object of the submenu to the item's submenu property. You can also call the addSubmenu() method of the parent NativeMenu object to create the item and set the submenu property at the same time.
  • To create a separator, call the NativeMenuItem constructor, passing in an empty string for the label and true for the isSeparator parameter.

Listen for select events on an item or a parent menu to detect when a menu command is selected. Neither submenus nor separators dispatch select events. Listen for displaying events to determine when a menu item is about to be displayed.

Property Detail
AIR-only 

checked

property
checked:Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Controls whether this menu item displays a checkmark.



Implementation
    public function get checked():Boolean
    public function set checked(value:Boolean):void
AIR-only 

data

property 
data:Object

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

An arbitrary data object associated with this menu item.

You can assign any object to this property. The assigned object is not used by the menu system, but is available to event handling code (through the target property of the event object). By default, the value of this property is null.



Implementation
    public function get data():Object
    public function set data(value:Object):void
AIR-only 

enabled

property 
enabled:Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Controls whether this menu item is enabled.



Implementation
    public function get enabled():Boolean
    public function set enabled(value:Boolean):void
AIR-only 

isSeparator

property 
isSeparator:Boolean  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Reports whether this item is a menu separator line.

Create a separator line by setting the isSeparator parameter in the NativeMenuItem constructor to true.



Implementation
    public function get isSeparator():Boolean
AIR-only 

keyEquivalent

property 
keyEquivalent:String

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The key equivalent for this menu item.

Set the keyEquivalent with a lowercase letter to assign a shortcut without a Shift-key modifier. Set with an uppercase letter to assign a shortcut with the Shift-key modifier.

By default, a key equivalent modifier (Ctrl on Windows or Linux and Command on Mac OS X) is included as part of the key equivalent. If you want the key equivalent to be a key with no modifier, set the keyEquivalentModifiers property to an empty array.



Implementation
    public function get keyEquivalent():String
    public function set keyEquivalent(value:String):void
AIR-only 

keyEquivalentModifiers

property 
keyEquivalentModifiers:Array

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The array of key codes for the key equivalent modifiers.

Use the constants defined in the Keyboard class to specify the modifier key codes. Valid modifer keys include:

  • Keyboard.ALTERNATE
  • Keyboard.COMMAND
  • Keyboard.CONTROL

If you do not assign any modifiers, then by default the Keyboard.CONTROL key is assigned on Windows or Linux and the Keyboard.COMMAND key is assigned on Mac OS X. If you do not want the key equivalent to include these modifiers, set this property to an empty array.

If you assign an uppercase letter to the keyEquivalent property, the Shift key is used as a modifier automatically. Setting keyEquivalentModifier to an empty array does not remove the Shift key as a modifier.



Implementation
    public function get keyEquivalentModifiers():Array
    public function set keyEquivalentModifiers(value:Array):void

AIR-only 

label

property 
label:String

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The display string of this menu item.



Implementation
    public function get label():String
    public function set label(value:String):void
AIR-only 

menu

property 
menu:NativeMenu  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The menu that contains this item.



Implementation
    public function get menu():NativeMenu
AIR-only 

mnemonicIndex

property 
mnemonicIndex:int

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The position of the mnemonic character in the menu item label.

The character at the specified position is the mnemonic character for the menu item. The index is zero-based, so the first character has an index of 0.

This property is ignored on operating systems that do not use menu mnemonics.



Implementation
    public function get mnemonicIndex():int
    public function set mnemonicIndex(value:int):void
AIR-only 

name

property 
name:String

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The name of this menu item.

The name value is not displayed and can be used as a locale-independent identifier. A name is not assigned automatically.



Implementation
    public function get name():String
    public function set name(value:String):void
AIR-only 

submenu

property 
submenu:NativeMenu

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The submenu associated with this menu item.

Assigning a NativeMenu object to this property changes the appearance and behavior of the menu item. A submenu item displays the submenu icon and no longer dispatches select events.

Note: Adding a menu as a submenu of itself (in a circular reference) can cause an application to hang.



Implementation
    public function get submenu():NativeMenu
    public function set submenu(value:NativeMenu):void

Event Detail
AIR-only 

displaying

Event
Event Object Type: flash.events.Event
property Event.type = flash.events.Event.DISPLAYING

Runtime Versions: AIR 1.0

Dispatched by this NativeMenuItem object immediately before the menu containing the item is displayed.

The target property of the event object references the NativeMenu object containing this NativeMenuItem object; the currentTarget property references this NativeMenuItem.

The Event.DISPLAYING constant defines the value of the type property of a displaying event object.

Note: This event does not go through a "capture phase" and is dispatched directly to the target, whether the target is on the display list or not.

This event has the following properties:

PropertyValue
bubblesfalse
cancelablefalse
currentTargetThe object that is actively processing the Event object with an event listener.
targetThe object that is about to be displayed.
AIR-only 

select

Event  
Event Object Type: flash.events.Event
property Event.type = flash.events.Event.SELECT

Runtime Versions: AIR 1.0

Dispatched whenever a menu item is selected by the user.

A select event bubbles from this item to its containing menu and on up through the parent menu chain to the root menu object. The target property of the event object references this NativeMenuItem object; the currentTarget property references the dispatching object (either this NativeMenuItem or an ancestral NativeMenu object).

Note: If the window containing the menu is in fullscreen mode, the NativeMenuItem object does not dispatch a select event when the user enters a keyboard equivalent for a menu item. You can, however, listen for a keyDown event dispatched by the stage property of the NativeWindow object.

The Event.SELECT constant defines the value of the type property of a select event object.

This event has the following properties:

PropertyValue
bubblesfalse
cancelablefalse; there is no default behavior to cancel.
currentTargetThe object that is actively processing the Event object with an event listener.
targetThe object on which an item has been selected.
