Implements IChildList, IFlexDisplayObject, IFlexModuleFactory, ISystemManager

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The SystemManager class manages an application window. Every application that runs on the desktop or in a browser has an area where the visuals of the application are displayed. It may be a window in the operating system or an area within the browser. That area is an application window and different from an instance of mx.core.Application, which is the main, or top-level, window within an application.

Every application has a SystemManager. The SystemManager sends an event if the size of the application window changes (you cannot change it from within the application, but only through interaction with the operating system window or browser). It parents all displayable things within the application like the main mx.core.Application instance and all popups, tooltips, cursors, and so on. Any object parented by the SystemManager is considered to be a top-level window, even tooltips and cursors.

The SystemManager also switches focus between top-level windows if there are more than one IFocusManagerContainer displayed and users are interacting with components within the IFocusManagerContainers.

All keyboard and mouse activity that is not expressly trapped is seen by the SystemManager, making it a good place to monitor activity should you need to do so.

If an application is loaded into another application, a SystemManager will still be created, but will not manage an application window, depending on security and domain rules. Instead, it will be the content of the Loader that loaded it and simply serve as the parent of the sub-application

The SystemManager maintains multiple lists of children, one each for tooltips, cursors, popup windows. This is how it ensures that popup windows "float" above the main application windows and that tooltips "float" above that and cursors above that. If you simply examine the numChildren property or call the getChildAt() method on the SystemManager, you are accessing the main application window and any other windows that aren't popped up. To get the list of all windows, including popups, tooltips and cursors, use the rawChildren property.

The SystemManager is the first display class created within an application. It is responsible for creating an mx.preloaders.Preloader that displays and mx.preloaders.SparkDownloadProgressBar while the application finishes loading, then creates the mx.core.Application instance.

Property Detail

application

property
application:IUIComponent  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The application parented by this SystemManager. SystemManagers create an instance of an Application even if they are loaded into another Application. Thus, this may not match mx.core.Application.application if the SWF has been loaded into another application.

Note that this property is not typed as mx.core.Application because of load-time performance considerations but can be coerced into an mx.core.Application.



Implementation
    public function get application():IUIComponent

childAllowsParent

property 
childAllowsParent:Boolean  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

An list of the custom cursors being parented by this ISystemManager.

An ISystemManager has various types of children, such as the Application, popups, top-most windows, tooltips, and custom cursors. You can access the custom cursors through the cursorChildren property.

The IChildList object has methods like getChildAt() and properties like numChildren. For example, cursorChildren.numChildren gives the number of custom cursors (which will be either 0 or 1) and, if a custom cursor exists, you can access it as cursorChildren.getChildAt(0).



Implementation
    public function get cursorChildren():IChildList

document

property 
document:Object

Language Version: ActionScript 3.0
Product Version: Flex 3

height

property 
height:Number[override]

Language Version: ActionScript 3.0

Constructor Detail

SystemManager

()Constructor
public function SystemManager()

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Constructor.

This is the starting point for all Flex applications. This class is set to be the root class of a Flex SWF file. Flash Player instantiates an instance of this class, causing this constructor to be called.

Method Detail

allowDomain

()method
public function allowDomain(... domains):void

Calls Security.allowDomain() for the SWF associated with this SystemManager plus all the SWFs assocatiated with RSLs preloaded by this SystemManager.

Parameters

... domains

allowInsecureDomain

()method 
public function allowInsecureDomain(... domains):void

Calls Security.allowInsecureDomain() for the SWF associated with this SystemManager plus all the SWFs assocatiated with RSLs preloaded by this SystemManager.

Parameters

... domains

create

()method 
public function create(... params):Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

A factory method that requests an instance of a definition known to the module. You can provide an optional set of parameters to let building factories change what they create based on the input. Passing null indicates that the default definition is created, if possible. This method is overridden in the autogenerated subclass.

Parameters

... params — An optional list of arguments. You can pass any number of arguments, which are then stored in an Array called parameters.

Returns
Object — An instance of the module, or null.

deployMouseShields

()method 
public function deployMouseShields(deploy:Boolean):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Deploy or remove mouse shields. Mouse shields block mouse input to untrusted applications. The reason you would want to block mouse input is because when you are dragging over an untrusted application you would normally not receive any mouse move events. The Flash Player does not send events across trusted/untrusted boundries due to security concerns. By covering the untrusted application with a mouse shield (assuming you are its parent) you can get mouse move message and the drag operation will work as expected.

Parameters

deploy:Booleantrue to deploy the mouse shields, false to remove the mouse shields.

getDefinitionByName

()method 
public function getDefinitionByName(name:String):Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Converts the given String to a Class or package-level Function. Calls the appropriate ApplicationDomain.getDefinition() method based on whether you are loaded into another application or not.

Parameters

name:String — Name of class, for example "mx.video.VideoManager".

Returns
Object — The Class represented by the name, or null.
