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 theisSeparator
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 theaddSubmenu()
method of the parent NativeMenu object to create the item and set thesubmenu
property at the same time. - To create a separator, call the NativeMenuItem constructor, passing in an empty
string for the label and
true
for theisSeparator
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 preparing
events to determine when
a menu item is about to be displayed or activated through a key equivalent.

checked | property |
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
enabled | property |
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
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
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 modifier 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

label | property |
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
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
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
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

flash.events.Event
property Event.type =
flash.events.Event.DISPLAYING
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 |
Dispatched by this NativeMenuItem object immediately before the menu containing the item is displayed.
The preparing
event supersedes the displaying
event and provides additional functionality. Listen for the
preparing
event or the displaying
event, but not both.
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:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The object that is about to be displayed. |
preparing | Event |
flash.events.Event
property Event.type =
flash.events.Event.PREPARING
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 2.6 |
Dispatched by this NativeMenuItem object when its key equivalent is pressed and immediately before the containing menu is displayed.
Listen to this event to update the item either before the containing menu is displayed, or when its key
equivalent is pressed by the user. The preparing
event is dispatched before the key equivalent
is fully evaluated. You can enable, disable, or remove the item from the menu in the preparing
event handler
and those changes will be in effect when the key equivalent is processed. For example, if you remove or disable this
menu item, then the sequence of events is effectively canceled
and no select
event is dispatched.
A preparing
event is also dispatched by the other items in a menu.
The preparing
event supersedes the displaying
event and provides additional functionality. Listen for the
preparing
event or the displaying
event, but not both.
Event.PREPARING
constant defines the value of the type
property of a preparing
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:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
currentTarget | The object that dispatched this event. |
target | The object that dispatched this event. |
select | Event |
flash.events.Event
property Event.type =
flash.events.Event.SELECT
Language Version: | ActionScript 3.0 |
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
(stage.displayState == StageDisplayState.FULL_SCREEN
),
the NativeMenuItem object does not dispatch a select
event
when the user enters a keyboard equivalent for a menu item.
Event.SELECT
constant defines the value of the type
property of a select
event object.
This event has the following properties:
Property | Value |
---|---|
bubbles | false |
cancelable | false ; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The object on which an item has been selected. |
