Note: Older SWF files created using ActionScript 1 or 2 share global states such as class definitions, singletons, and global
variables if they are loaded into the same window. If such a SWF file relies on untouched global states to work correctly,
it cannot be loaded more than once into the same window, or loaded into the same window as another SWF file using
overlapping class definitions and variables. This content can be loaded into separate windows.
Loading HTML content into a NativeWindow
To load HTML content into a NativeWindow, you can either add an HTMLLoader object to the window stage and
load the HTML content into the HTMLLoader, or create a window that already contains an HTMLLoader object by
using the HTMLLoader.createRootWindow()method. The following example displays HTML content within a 300
by 500 pixel display area on the stage of a native window:
//newWindow is a NativeWindow instance
var htmlView:HTMLLoader = new HTMLLoader();
htmlView.width = 300;
htmlView.height = 500;
//set the stage so display objects are added to the top-left and not scaled
newWindow.stage.align = "TL";
newWindow.stage.scaleMode = "noScale";
newWindow.stage.addChild( htmlView );
//urlString is the URL of the HTML page to load
htmlView.load( new URLRequest(urlString) );
To load an HTML page into a Flex application, you can use the Flex HTML component.
SWF content in an HTML file is not displayed if the window uses transparency (that is the transparent property of
the window is true) unless the wmode parameter of the object or embed tag used to reference the SWF file is set to
either opaque or transparent. Since the default wmode value is window, by default, SWF content is not displayed in
a transparent window. PDF content is not displayed in a transparent window no matter what wmode value is used.
Also, neither SWF nor PDF content is displayed if the HTMLLoader control is scaled, rotated, or if the HTMLLoader
alpha property is set to a value other than 1.0.
