+ // summary:
+ // The goal of dojox.flash is to make it easy to extend Flash's capabilities
+ // into an Ajax/DHTML environment.
+ //
+ // dojox.flash provides an easy object for interacting with the Flash plugin.
+ // This object provides methods to determine the current version of the Flash
+ // plugin (dojox.flash.info); write out the necessary markup to
+ // dynamically insert a Flash object into the page (dojox.flash.Embed; and
+ // do dynamic installation and upgrading of the current Flash plugin in
+ // use (dojox.flash.Install). If you want to call methods on the Flash object
+ // embedded into the page it is your responsibility to use Flash's ExternalInterface
+ // API and get a reference to the Flash object yourself.
+ //
+ // To use dojox.flash, you must first wait until Flash is finished loading
+ // and initializing before you attempt communication or interaction.
+ // To know when Flash is finished use dojo.connect:
+ //
+ // dojo.connect(dojox.flash, "loaded", myInstance, "myCallback");
+ //
+ // Then, while the page is still loading provide the file name:
+ //
+ // dojox.flash.setSwf(dojo.moduleUrl("dojox", "_storage/storage.swf"));
+ //
+ // If no SWF files are specified, then Flash is not initialized.
+ //
+ // Your Flash must use Flash's ExternalInterface to expose Flash methods and
+ // to call JavaScript.
+ //
+ // setSwf can take an optional 'visible' attribute to control whether
+ // the Flash object is visible or not on the page; the default is visible:
+ //
+ // dojox.flash.setSwf(dojo.moduleUrl("dojox", "_storage/storage.swf"),
+ // false);
+ //
+ // Once finished, you can query Flash version information:
+ //
+ // dojox.flash.info.version
+ //
+ // Or can communicate with Flash methods that were exposed:
+ //
+ // var f = dojox.flash.get();
+ // var results = f.sayHello("Some Message");
+ //
+ // Your Flash files should use DojoExternalInterface.as to register methods;
+ // this file wraps Flash's normal ExternalInterface but correct various
+ // serialization bugs that ExternalInterface has.
+ //
+ // Note that dojox.flash is not meant to be a generic Flash embedding
+ // mechanism; it is as generic as necessary to make Dojo Storage's
+ // Flash Storage Provider as clean and modular as possible. If you want
+ // a generic Flash embed mechanism see SWFObject
+ // (http://blog.deconcept.com/swfobject/).
+ //
+ // Notes:
+ // Note that dojox.flash can currently only work with one Flash object
+ // on the page; it does not yet support multiple Flash objects on
+ // the same page.
+ //
+ // Your code can detect whether the Flash player is installing or having
+ // its version revved in two ways. First, if dojox.flash detects that
+ // Flash installation needs to occur, it sets dojox.flash.info.installing
+ // to true. Second, you can detect if installation is necessary with the
+ // following callback:
+ //
+ // dojo.connect(dojox.flash, "installing", myInstance, "myCallback");
+ //
+ // You can use this callback to delay further actions that might need Flash;
+ // when installation is finished the full page will be refreshed and the
+ // user will be placed back on your page with Flash installed.
+ //
+ // -------------------
+ // Todo/Known Issues
+ // -------------------
+ // * On Internet Explorer, after doing a basic install, the page is
+ // not refreshed or does not detect that Flash is now available. The way
+ // to fix this is to create a custom small Flash file that is pointed to
+ // during installation; when it is finished loading, it does a callback
+ // that says that Flash installation is complete on IE, and we can proceed
+ // to initialize the dojox.flash subsystem.
+ // * Things aren't super tested for sending complex objects to Flash
+ // methods, since Dojo Storage only needs strings
+ //
