 | Starting with Flex 4.0, Adobe recommends that you use the spark.components.Application class as an alternative to this class. |
Flex defines a default, or Application, container that lets you start adding content to your application without explicitly defining another container. Flex creates this container from the
<mx:Application>
tag, the first tag in an MXML application file.
While you might find it convenient to use the Application container
as the only container in your application, in most cases you explicitly
define at least one more container before you add any controls
to your application.
Applications support a predefined plain style that sets a white background, left alignment, and removes all margins. To use this style, do the following:
<mx:Application styleName="plain" />
This is equivalent to setting the following style attributes:
backgroundColor="0xFFFFFF"
horizontalAlign="left"
paddingLeft="0"
paddingTop="0"
paddingBottom="0"
paddingRight="0"
MXML Syntax

Public Constants
Property Detail
application | property |
application:Object [read-only] Deprecated since 4.0: Please Use FlexGlobals.topLevelApplication
| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A reference to the top-level application.
In general, there can be a hierarchy of Application objects,
because an Application can use a SWFLoader control to dynamically
load another Application.
The parentApplication property of a UIComponent can be
used to access the sub-Application in which that UIComponent lives,
and to walk up the hierarchy to the top-level Application.
This property has been deprecated starting in Flex4. Note that this property will still return applications of type mx.core.Application and mx.core.WindowedApplication as in previous versions. Starting in Flex 4 it will also return applications of type spark.components.Application or spark.components.WindowedApplication.
Implementation
public static function get application():ObjectcontrolBar | property |
public var controlBar:IUIComponent| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The ApplicationControlBar for this Application.
The default value is null.
Related API Elements

public var frameRate:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies the frame rate of the application.
Note: This property cannot be set by ActionScript code; it must be set in MXML code.
The default value is 24.
historyManagementEnabled | property |
public var historyManagementEnabled:Boolean = true| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
If false, the history manager will be disabled.
Setting to false is recommended when using the BrowserManager.
The default value is true.
pageTitle | property |
public var pageTitle:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies a string that appears in the title bar of the browser.
This property provides the same functionality as the
HTML <title> tag.
Note: This property cannot be set by ActionScript code; it must be set in MXML code. The value set in MXML code is designed to be used by a tool to update the HTML templates provided with the SDK.
The default value is "".
parameters | property |
parameters:Object [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The parameters property returns an Object containing name-value pairs representing the parameters provided to this Application.
You can use a for-in loop to extract all the names and values from the parameters Object.
There are two sources of parameters: the query string of the Application's URL, and the value of the FlashVars HTML parameter (this affects only the main Application).
Implementation
public function get parameters():Objectpreloader | property |
public var preloader:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The application container supports an application preloader that uses a download progress bar to show the download and initialization progress of an application SWF file. By default, the application preloader is enabled. The preloader tracks how many bytes have been downloaded and continually updates the progress bar.
Use this property to specify the path of a component that defines a custom progress indicator. To create a custom progress indicator, you typically create a subclass of the DownloadProgressBar class, or create a subclass of the flash.display.Sprite class that implements the mx.preloaders.IPreloaderDisplay interface.
Note: This property cannot be set by ActionScript code; it must be set in MXML code.
Related API Elements
preloaderChromeColor | property |
public var preloaderChromeColor:uint| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies the base color used by the default preloader component. This property
has the same effect as the chromeColor style used by the Spark skins.
Typically this property should be set to the same value as the chromeColor
style used by the application.
Note: This property cannot be set by ActionScript code; it must be set in MXML code.
resetHistory | property |
public var resetHistory:Boolean = true| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
If true, the application's history state is reset
to its initial state whenever the application is reloaded.
Applications are reloaded when any of the following occurs:
- The user clicks the browser's Refresh button.
- The user navigates to another web page, and then clicks the browser's Back button to return to the Flex application.
- The user loads a Flex application from the browser's Favorites or Bookmarks menu.
The default value is true.

public var scriptRecursionLimit:int| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies the maximum depth of Flash Player or AIR call stack before the player stops. This is essentially the stack overflow limit.
Note: This property cannot be set by ActionScript code; it must be set in MXML code.
The default value is 1000.
scriptTimeLimit | property |
public var scriptTimeLimit:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies the maximum duration, in seconds, that an ActionScript event handler can execute before Flash Player or AIR assumes that it is hung, and aborts it. The maximum allowable value that you can set is 60 seconds.
The default value is 60.

URL where the application's source can be viewed. Setting this
property inserts a "View Source" menu item into the application's
default context menu. Selecting the menu item opens the
viewSourceURL in a new window.
You must set the viewSourceURL property
using MXML, not using ActionScript, as the following example shows:
<mx:Application viewSourceURL="http://path/to/source">
...
</mx:Application>

The properties of the event object have the following values:
| Property | Value |
|---|---|

currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
