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():Object

preloader

property

public var preloader:Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

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 SparkDownloadProgressBar or 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.

Note: This property cannot be set by ActionScript code; it must be set in MXML code.

resizeForSoftKeyboard

property

resizeForSoftKeyboard:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Some devices do not support a hardware keyboard. Instead, these devices use a keyboard that opens on the screen when necessary. The screen keyboard, also called a soft or virtual keyboard, closes after the user enters the information, or when the user cancels the operation. A value of true means the application is resized when the soft keyboard is open or closed.

To enable application resizing, you must also set the <softKeyboardBehavior> attribute in the application's xml descriptor file to none.

The default value is false.

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

runtimeDPI

property

runtimeDPI:Number [read-only]

Language Version:

ActionScript 3.0

Product Version:

property

splashScreenImage:Class

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

splashScreenImage="@Embed('Default.png')"

Note: The property has effect only when the preloader property is set to spark.preloaders.SplashScreen. The spark.preloaders.SplashScreen class is the default preloader for Mobile Flex applications. This property cannot be set by ActionScript code; it must be set in MXML code.

Note: You must add the frameworks\libs\mobile\mobilecomponents.swc to the library path of the application to support the splash screen in a desktop application.

Implementation
public function get splashScreenImage():Class
public function set splashScreenImage(value:Class):void

splashScreenMinimumDisplayTime

property

public var splashScreenMinimumDisplayTime:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10, AIR 2.5

Minimum amount of time, in milliseconds, to show the splash screen image. Specify the splash screen image by using the splashScreenImage property.

Note: The property has effect only when the splashScreenImage property is set and the preloader property is set to spark.preloaders.SplashScreen. The spark.preloaders.SplashScreen class is the default preloader for Mobile Flex applications. This property cannot be set by ActionScript code; it must be set in MXML code.

Note: You must add the frameworks\libs\mobile\mobilecomponents.swc to the library path of the application to support the splash screen in a desktop application.

The default value is 1000.

splashScreenScaleMode

splashScreenScaleMode

property

public var splashScreenScaleMode:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10, AIR 2.5

The splash screen image scale mode:

A value of none implies that the image size is set to match its intrinsic size.
A value of stretch sets the width and the height of the image to the stage width and height, possibly changing the content aspect ratio.
A value of letterbox sets the width and height of the image as close to the stage width and height as possible while maintaining aspect ratio. The image is stretched to a maximum of the stage bounds, with spacing added inside the stage to maintain the aspect ratio if necessary.
A value of zoom is similar to letterbox, except that zoom stretches the image past the bounds of the stage, to remove the spacing required to maintain aspect ratio. This setting has the effect of using the entire bounds of the stage, but also possibly cropping some of the image.

The portion of the stage that is not covered by the image shows in the Application container's backgroundColor.

Note: You must add the frameworks\libs\mobile\mobilecomponents.swc to the library path of the application to support the splash screen in a desktop application.

The default value is "none".

Event Object Type: mx.events.FlexEvent
property FlexEvent.type = mx.events.FlexEvent.APPLICATION_COMPLETE

Language Version:

ActionScript 3.0

Product Version:

Dispatched after the Application has been initialized, processed by the LayoutManager, and attached to the display list.

The FlexEvent.APPLICATION_COMPLETE constant defines the value of the type property of the event object for a applicationComplete event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`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.
