Description
The System object provides information about, and control over, features of the Flash Player and the system on which it is running. With the exception of showSettings( ) (used to display the Flash Player Settings dialog box) and useCodepage (used to control the character encoding mode), Player and system features are accessed through the Capabilities and Security objects, which themselves are stored as properties of System. The Capabilities object is documented separately as the CapabilitiesObject (under the letter "C") in this Language Reference. The Security object's single method, allowDomain( ), which can permit movies loaded from different domains to access and control each other, is documented under System.security.allowDomain( ).
Note that System is a predefined object, not a class. Its properties and methods are accessed directly, as in:
System.showSettings(0); // Displays the Privacy tab of the Settings dialog box
