Property Detail
AIR-only 

activeWindow

property
activeWindow:NativeWindow  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The active application window.

If the active desktop window does not belong to this application, or there is no active window, activeWindow is null.



Implementation
    public function get activeWindow():NativeWindow
AIR-only 

applicationDescriptor

property 
applicationDescriptor:XML  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The contents of the application descriptor file for this AIR application.



Implementation
    public function get applicationDescriptor():XML

Example  ( How to use this example )
The following example reads the copyright and version elements from the application descriptor file. Note that you must use the default namespace defined in the application descriptor XML.
var appDescriptor:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appDescriptor.namespace();
var appCopyright:String = appDescriptor.ns::copyright;
var appVersion:String = appDescriptor.ns::version;
trace("appId:", appCopyright);
trace("version:", appVersion);
AIR-only 

applicationID

property 
applicationID:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The application ID of this application.

The value of this ID is set in the application descriptor file.



Implementation
    public function get applicationID():String
AIR-only 

autoExit

property 
autoExit:Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Specifies whether the application should automatically terminate when all windows have been closed.

When autoExit is true, which is the default, the application terminates when all windows are closed. Both exiting and exit events are dispatched. When autoExit is false, you must call NativeApplication.nativeApplication.exit() to terminate the application.



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

icon

property 
icon:InteractiveIcon  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The application icon.

Use NativeApplication.supportsDockIcon and NativeApplication.supportsSystemTrayIcon to determine the icon class. The type will be one of the subclasses of InteractiveIcon. On Mac® OS X, NativeApplication.icon is an object of type DockIcon. On Windows®, NativeApplication.icon is an object of type SystemTrayIcon. On Linux, an application icon is not always supported. In this case, the icon property is null.

The icon object is automatically created, but it is not initialized with image data. On some operating systems, such as Mac OS X, a default image is supplied. On others, such as Windows, the icon is not displayed unless image data is assigned to it. To assign an icon image, set the icon.bitmaps property with an array containing at least one BitmapData object. If more than one BitmapData object is included in the array, then the operating system chooses the image that is closest in size to the icon's display dimensions, scaling the image if necessary.



Implementation
    public function get icon():InteractiveIcon

AIR-only 

idleThreshold

property 
idleThreshold:int

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The number of seconds that must elapse without keyboard or mouse input before a userIdle event is dispatched.

By default, the idle threshold is 300 seconds (5 minutes). The acceptable range of values is from 5 (5 seconds) through 86,400 (1 day), inclusive.



Implementation
    public function get idleThreshold():int
    public function set idleThreshold(value:int):void

Throws
ArgumentError — If you attempt to set the property to an invalid value. The acceptable range of values is from 5 (5 seconds) through 86,400 (1 day), inclusive.

AIR-only 

menu

property 
menu:NativeMenu

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The application menu.

Application menus are supported when NativeApplication.nativeApplication.supportsMenu is true. Not all operating systems support application menus. For example, application menus are supported on Mac OS X, but not on Windows or Linux. Assigning a NativeMenu object to this property when NativeApplication.nativeApplication.supportsMenu is false is allowed, but does nothing. Be sure to use the NativeApplication.nativeApplication.supportsMenu property to determine whether the operating system supports application menus. Using other means (such as Capabilities.os) to determine support can lead to programming errors (if some possible target operating systems are not considered).

Note: On Mac OS X, the menu property references the operating-system-supplied default application menu. You can modify the existing menu structure by adding and removing items and submenus, and by adding event listeners. You can also replace the default menus entirely by assigning a new NativeMenu object to this menu property.



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

See also

AIR-only 

nativeApplication

property 
nativeApplication:NativeApplication  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Implementation
    public static function get nativeApplication():NativeApplication

Throws
Error — If accessed by content outside the application security sandbox.
AIR-only 

openedWindows

property 
openedWindows:Array  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

An array containing all the open native windows of this application.



Implementation
    public function get openedWindows():Array
AIR-only 

publisherID

property 
publisherID:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The publisher ID of this application.

The value of this ID is set in the application's publisherid file, which is generated at installation from the certificate chain used to sign the application.



Implementation
    public function get publisherID():String
AIR-only 

runtimePatchLevel

property 
runtimePatchLevel:uint  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The patch level of the runtime hosting this application.



Implementation
    public function get runtimePatchLevel():uint
AIR-only 

runtimeVersion

property 
runtimeVersion:String  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

The version number of the runtime hosting this application.



Implementation
    public function get runtimeVersion():String
AIR-only 

startAtLogin

property 
startAtLogin:Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Specifies whether this application is automatically launched whenever the current user logs in.

The startAtLogin property reflects the status of the operating-system-defined mechanism for designating that an application should start automatically when a user logs in. The user can change the status manually by using the operating system user interface. This property reflects the current status, whether the status was last changed by the AIR application or by the operating system.



Implementation
    public function get startAtLogin():Boolean
    public function set startAtLogin(value:Boolean):void

Throws
IllegalOperationError — On Windows when another application with the same name (but with a different path to the executable) is already set to launch when this user logs in.
 
IllegalOperationError — If this application is not installed, which may be the case when launched by the AIR Debug Launcher (ADL).
AIR-only 

supportsDockIcon

property 
supportsDockIcon:Boolean  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Indicates whether AIR supports application dock icons on the current operating system.

If true, the NativeApplication.icon property is of type DockIcon.

Mac OS X and various Linux® user interfaces provide an application "dock" containing icons for applications that are running or are frequently used.

Be sure to use the NativeApplication.supportsDockIcon property to determine whether the operating system supports application dock icons. Using other means (such as Capabilities.os) to determine support can lead to programming errors (if some possible target operating systems are not considered).



Implementation
    public static function get supportsDockIcon():Boolean

See also

AIR-only 

supportsMenu

property 
supportsMenu:Boolean  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Specifies whether the current operating system supports a global application menu bar.

When true, the NativeApplication.menu property can be used to define (or access) a native application menu.

Be sure to use the NativeApplication.supportsMenu property to determine whether the operating system supports the application menu bar. Using other means (such as Capabilities.os) to determine support can lead to programming errors (if some possible target operating systems are not considered).



Implementation
    public static function get supportsMenu():Boolean

See also

AIR-only 

supportsSystemTrayIcon

property 
supportsSystemTrayIcon:Boolean  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Specifies whether AIR supports system tray icons on the current operating system.

If true, the NativeApplication.icon property is of type SystemTrayIcon.

Be sure to use the NativeApplication.supportsSystemTrayIcon property to determine whether the operating system supports system tray icons. Using other means (such as Capabilities.os) to determine support can lead to programming errors (if some possible target operating systems are not considered).

Note: On Windows, the system tray region of the task bar is officially called the Notification Area.



Implementation
    public static function get supportsSystemTrayIcon():Boolean

Method Detail

AIR-only activate

()method
public function activate(window:NativeWindow = null):void

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Activates this application.

Under some circumstances determined by the operating system, this method does not activate an application. Most operating systems restrict the ability of an application to activate itself to prevent it from accidentally or maliciously making it impossible for a user to use other applications.

If the operating system allows activation, then the specified window is activated and brought to the desktop foreground; that is, in front of the windows of other applications. (If the window parameter is null, then a visible window of this application is activated.)

The activate() method has no effect if the application has no visible windows.

The activate operation is synchronous.

Parameters

window:NativeWindow (default = null) — The NativeWindow object of the window to activate along with the application.


Events
activate:Event — Dispatched if the activation state changes.

AIR-only addEventListener

()method 
override public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void

Runtime Versions: AIR 1.0

Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event. You can register event listeners on all nodes in the display list for a specific type of event, phase, and priority.

After you successfully register an event listener, you cannot change its priority through additional calls to addEventListener(). To change a listener's priority, you must first call removeListener(). Then you can register the listener again with the new priority level.

Keep in mind that after the listener is registered, subsequent calls to addEventListener() with a different type or useCapture value result in the creation of a separate listener registration. For example, if you first register a listener with useCapture set to true, it listens only during the capture phase. If you call addEventListener() again using the same listener object, but with useCapture set to false, you have two separate listeners: one that listens during the capture phase and another that listens during the target and bubbling phases.

You cannot register an event listener for only the target phase or the bubbling phase. Those phases are coupled during registration because bubbling applies only to the ancestors of the target node.

If you no longer need an event listener, remove it by calling removeEventListener(), or memory problems could result. Event listeners are not automatically removed from memory because the garbage collector does not remove the listener as long as the dispatching object exists (unless the useWeakReference parameter is set to true).

Copying an EventDispatcher instance does not copy the event listeners attached to it. (If your newly created node needs an event listener, you must attach the listener after creating the node.) However, if you move an EventDispatcher instance, the event listeners attached to it move along with it.

If the event listener is being registered on a node while an event is being processed on this node, the event listener is not triggered during the current phase but can be triggered during a later phase in the event flow, such as the bubbling phase.

If an event listener is removed from a node while an event is being processed on the node, it is still triggered by the current actions. After it is removed, the event listener is never invoked again (unless registered again for future processing).

Parameters

type:String — The type of event.
 
listener:Function — The listener function that processes the event. This function must accept an Event object as its only parameter and must return nothing, as this example shows:
function(evt:Event):void

The function can have any name.

 
useCapture:Boolean (default = false)Determines whether the listener works in the capture phase or the target and bubbling phases. If useCapture is set to true, the listener processes the event only during the capture phase and not in the target or bubbling phase. If useCapture is false, the listener processes the event only during the target or bubbling phase. To listen for the event in all three phases, call addEventListener twice, once with useCapture set to true, then again with useCapture set to false.
 
priority:int (default = 0) — The priority level of the event listener. The priority is designated by a signed 32-bit integer. The higher the number, the higher the priority. All listeners with priority n are processed before listeners of priority n-1. If two or more listeners share the same priority, they are processed in the order in which they were added. The default priority is 0.
 
useWeakReference:Boolean (default = false) — Determines whether the reference to the listener is strong or weak. A strong reference (the default) prevents your listener from being garbage-collected. A weak reference does not.

Class-level member functions are not subject to garbage collection, so you can set useWeakReference to true for class-level member functions without subjecting them to garbage collection. If you set useWeakReference to true for a listener that is a nested inner function, the function will be garbage-collected and no longer persistent. If you create references to the inner function (save it in another variable) then it is not garbage-collected and stays persistent.

AIR-only clear

()method 
public function clear():Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Invokes an internal delete command on the focused display object.

This function call is ignored if the focused object does not implement the command. Only display objects descending from the TextField or HTMLLoader classes currently implement this command.

Note: The clear() command deletes selected text. If nothing is selected, it does not clear all text.

Returns
Booleantrue.

AIR-only copy

()method 
public function copy():Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Invokes an internal copy command on the focused display object.

This function call is ignored if the component does not implement the command. Only display objects descending from the TextField or HTMLLoader classes currently implement this command.

Returns
Boolean

AIR-only cut

()method 
public function cut():Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Invokes an internal cut command on the focused display object.

This function call is ignored if the component does not implement the command. Only display objects descending from the TextField or HTMLLoader classes currently implement this commands.

Returns
Booleantrue.

AIR-only dispatchEvent

()method 
override public function dispatchEvent(event:Event):Boolean

Runtime Versions: AIR 1.0

Dispatches an event into the event flow. The event target is the EventDispatcher object upon which the dispatchEvent() method is called.

Parameters

event:Event — The Event object that is dispatched into the event flow. If the event is being redispatched, a clone of the event is created automatically. After an event is dispatched, its target property cannot be changed, so you must create a new copy of the event for redispatching to work.

Returns
Boolean — A value of true if the event was successfully dispatched. A value of false indicates failure or that preventDefault() was called on the event.

AIR-only exit

()method 
public function exit(errorCode:int = 0):void

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Terminates this application.

The call to the exit() method will return; the shutdown sequence does not begin until the currently executing code (such as a current event handler) has completed. Pending asynchronous operations are canceled and may or may not complete.

Note that an exiting event is not dispatched. If an exiting event is required by application logic, call NativeApplication.nativeApplication.dispatchEvent(), passing in an Event object of type exiting. Likewise, closing and close events are not dispatched before application windows are closed. If windows should be notified before your application exits, you can dispatch closing events for each open window. If a window close event is required, call the window's close() method before exiting.

Parameters

errorCode:int (default = 0) — The exit code reported to the operating system when this application exits.

AIR-only getDefaultApplication

()method 
public function getDefaultApplication(extension:String):String

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0

Gets the default application for opening files with the specified extension.

Note: This method can only be used with file types declared in the fileTypes statement of the application descriptor.

Parameters

extension:String — A String containing the extension of the file type of interest (without the ".").

Returns
String — The path of the default application.

Throws
Error — If the extension parameter does not contain one of the file extensions declared in the application descriptor.

Event Detail
AIR-only 

activate

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

Runtime Versions: AIR 1.0

Dispatched when this application becomes the active desktop application.

The ACTIVATE constant defines the value of the type property of an activate event object.

Note: This event has neither a "capture phase" nor a "bubble phase", which means that event listeners must be added directly to any potential targets, whether the target is on the display list or not.

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.
targetAny DisplayObject instance with a listener registered for the activate event.
AIR-only 

browserInvoke

Event  
Event Object Type: flash.events.BrowserInvokeEvent
property BrowserInvokeEvent.type = flash.events.BrowserInvokeEvent.Browser_INVOKE

Runtime Versions: AIR 1.0

Dispatched when an application is invoked by a SWF file running in the user's browser.

Browser invocation is permitted only if an application specifies the following in the application descriptor file:

<allowBrowserInvocation>true</allowBrowserInvocation>

AIR-only 

deactivate

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

Runtime Versions: AIR 1.0

Dispatched when the desktop focus is switched to a different application.

The Event.DEACTIVATE constant defines the value of the type property of a deactivate event object.

Note: This event has neither a "capture phase" nor a "bubble phase", which means that event listeners must be added directly to any potential targets, whether the target is on the display list or not.

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.
targetAny DisplayObject instance with a listener registered for the deactivate event.
AIR-only 

exiting

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

Runtime Versions: AIR 1.0

Dispatched when the application exit sequence is started.

The exiting event is dispatched when application exit is initiated by the operating system; for example, when a user issues the Cmd-Q key sequence on Mac OS X, or when the autoExit property of the NativeApplication object is true and the last application window is closed. Canceling this event prevents the application from exiting.

Note: Calling the NativeApplication exit() method does not cause an exiting event to be dispatched. To warn components of an impending exit, dispatch the exiting event before calling exit()

The Event.EXITING constant defines the value of the type property of an exiting event object.

This event has the following properties:

PropertyValue
bubblesfalse
cancelabletrue; canceling this event object stops the exit operation.
currentTargetThe NativeApplication object.
targetThe NativeApplication object.
AIR-only 

invoke

Event  
Event Object Type: flash.events.InvokeEvent
property InvokeEvent.type = flash.events.InvokeEvent.INVOKE

Runtime Versions: AIR 1.0

Dispatched when an application is invoked.

When an application is invoked a second time, another instance of the application is not started. Instead, the first instance receives an additional invoke event. It is the responsibility of the application to handle subsequent invoke events appropriately.

Note: All invoke events are queued. When a listener for this event is registered, it receives all events in the queue as well as any new events. Queued events may be delivered before or after any new invoke events.

The InvokeEvent.INVOKE constant defines the value of the type property of an InvokeEvent object.

The InvokeEvent object has the following properties:

PropertiesValues
argumentsThe array of string arguments passed during this invocation.
currentDirectorya File object representing the directory that should be used to resolve any relative paths in the arguments array.
reasona code indicating whether the invoke event was dispatched because the application started automatically at login (InvokeEventReason.LOGIN), or for another reason (InvokeEventReason.STANDARD). Available as of AIR version 1.5.1.
bubblesfalse.
cancelablefalse; there is no default behavior to cancel.
currentTargetIndicates the object that is actively processing this InvokeEvent object with an event listener.
targetAlways the NativeApplication object.
AIR-only 

networkChange

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

Dispatched when either a new network connection becomes available or an existing network connection is lost.

A networkChange event does not necessarily mean that the host computer has gone online or offline; it may just be transitioning from one type of connection to another. Applications can use this event to help optimize the task of monitoring remote resource availability. The dispatch of a networkChange event is often a good time to verify the availability of any remote resources.

Note: There may be a short delay between a network change and the delivery of this event.
