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

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

Every application has an ISystemManager. The ISystemManager 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 items within the application, such as the main mx.core.Application instance and all popups, tooltips, cursors, an so on. Any object parented by the ISystemManager is considered to be a "top-level" window, even tooltips and cursors.

The ISystemManager 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 ISystemManager, making it a good place to monitor activity should you need to do so.

If an application is loaded into another application, an ISystemManager 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 ISystemManager 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 examine the numChildren property or getChildAt() method on the ISystemManager 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.

Method Detail
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:Boolean — true 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
