+/**
+ The goal of dojo.flash is to make it easy to extend Flash's capabilities
+ into an AJAX/DHTML environment. Robust, performant, reliable
+ JavaScript/Flash communication is harder than most realize when they
+ delve into the topic, especially if you want it
+ to work on Internet Explorer, Firefox, and Safari, and to be able to
+ push around hundreds of K of information quickly. Dojo.flash makes it
+ possible to support these platforms; you have to jump through a few
+ hoops to get its capabilites, but if you are a library writer
+ who wants to bring Flash's storage or streaming sockets ability into
+ DHTML, for example, then dojo.flash is perfect for you.
+
+ Dojo.flash provides an easy object for interacting with the Flash plugin.
+ This object provides methods to determine the current version of the Flash
+ plugin (dojo.flash.info); execute Flash instance methods
+ independent of the Flash version
+ being used (dojo.flash.comm); write out the necessary markup to
+ dynamically insert a Flash object into the page (dojo.flash.Embed; and
+ do dynamic installation and upgrading of the current Flash plugin in
+ use (dojo.flash.Install).
+
+ To use dojo.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.event.connect:
+
+ dojo.event.connect(dojo.flash, "loaded", myInstance, "myCallback");
+
+ Then, while the page is still loading provide the file name
+ and the major version of Flash that will be used for Flash/JavaScript
+ communication (see "Flash Communication" below for information on the
+ different kinds of Flash/JavaScript communication supported and how they
+ depend on the version of Flash installed):
+
+ dojo.flash.setSwf({flash6: "src/storage/storage_flash6.swf",
+ flash8: "src/storage/storage_flash8.swf"});
+
+ This will cause dojo.flash to pick the best way of communicating
+ between Flash and JavaScript based on the platform.
+
+ If no SWF files are specified, then Flash is not initialized.
+
+ Your Flash must use DojoExternalInterface to expose Flash methods and
+ to call JavaScript; see "Flash Communication" below for details.
+
+ setSwf can take an optional 'visible' attribute to control whether
+ the Flash object is visible or not on the page; the default is visible:
+
+ dojo.flash.setSwf({flash6: "src/storage/storage_flash6.swf",
+ flash8: "src/storage/storage_flash8.swf",
+ visible: false});
+
+ Once finished, you can query Flash version information:
+
+ dojo.flash.info.version
+
+ Or can communicate with Flash methods that were exposed:
+
+ var results = dojo.flash.comm.sayHello("Some Message");
+
+ Only string values are currently supported for both arguments and
+ for return results. Everything will be cast to a string on both
+ the JavaScript and Flash sides.
+
+ -------------------
+ Flash Communication
+ -------------------
+
+ dojo.flash allows Flash/JavaScript communication in
+ a way that can pass large amounts of data back and forth reliably and
+ very fast. The dojo.flash
+ framework encapsulates the specific way in which this communication occurs,
+ presenting a common interface to JavaScript irrespective of the underlying
+ Flash version.
+
+ There are currently three major ways to do Flash/JavaScript communication
+ in the Flash community:
+
+ 1) Flash 6+ - Uses Flash methods, such as SetVariable and TCallLabel,
+ and the fscommand handler to do communication. Strengths: Very fast,
+ mature, and can send extremely large amounts of data; can do
+ synchronous method calls. Problems: Does not work on Safari; works on
+ Firefox/Mac OS X only if Flash 8 plugin is installed; cryptic to work with.
+
+ 2) Flash 8+ - Uses ExternalInterface, which provides a way for Flash
+ methods to register themselves for callbacks from JavaScript, and a way
+ for Flash to call JavaScript. Strengths: Works on Safari; elegant to
+ work with; can do synchronous method calls. Problems: Extremely buggy
+ (fails if there are new lines in the data, for example); performance
+ degrades drastically in O(n^2) time as data grows; locks up the browser while
+ it is communicating; does not work in Internet Explorer if Flash
+ object is dynamically added to page with document.writeln, DOM methods,
+ or innerHTML.
+
+ 3) Flash 6+ - Uses two seperate Flash applets, one that we
+ create over and over, passing input data into it using the PARAM tag,
+ which then uses a Flash LocalConnection to pass the data to the main Flash
+ applet; communication back to Flash is accomplished using a getURL
+ call with a javascript protocol handler, such as "javascript:myMethod()".
+ Strengths: the most cross browser, cross platform pre-Flash 8 method
+ of Flash communication known; works on Safari. Problems: Timing issues;
+ clunky and complicated; slow; can only send very small amounts of
+ data (several K); all method calls are asynchronous.
+
+ dojo.flash.comm uses only the first two methods. This framework
+ was created primarily for dojo.storage, which needs to pass very large
+ amounts of data synchronously and reliably across the Flash/JavaScript
+ boundary. We use the first method, the Flash 6 method, on all platforms
+ that support it, while using the Flash 8 ExternalInterface method
+ only on Safari with some special code to help correct ExternalInterface's
+ bugs.
+
+ Since dojo.flash needs to have two versions of the Flash
+ file it wants to generate, a Flash 6 and a Flash 8 version to gain
+ true cross-browser compatibility, several tools are provided to ease
+ development on the Flash side.
+
+ In your Flash file, if you want to expose Flash methods that can be
+ called, use the DojoExternalInterface class to register methods. This
+ class is an exact API clone of the standard ExternalInterface class, but
+ can work in Flash 6+ browsers. Under the covers it uses the best
+ mechanism to do communication:
+
+ class HelloWorld{
+ function HelloWorld(){
+ // Initialize the DojoExternalInterface class
+ DojoExternalInterface.initialize();
+
+ // Expose your methods
+ DojoExternalInterface.addCallback("sayHello", this, this.sayHello);
+
+ // Tell JavaScript that you are ready to have method calls
+ DojoExternalInterface.loaded();
+
+ // Call some JavaScript
+ var resultsReady = function(results){
+ trace("Received the following results from JavaScript: " + results);
+ }
+ DojoExternalInterface.call("someJavaScriptMethod", resultsReady,
+ someParameter);
+ }
+
+ function sayHello(){ ... }
+
+ static main(){ ... }
+ }
+
+ DojoExternalInterface adds two new functions to the ExternalInterface
+ API: initialize() and loaded(). initialize() must be called before
+ any addCallback() or call() methods are run, and loaded() must be
+ called after you are finished adding your callbacks. Calling loaded()
+ will fire the dojo.flash.loaded() event, so that JavaScript can know that
+ Flash has finished loading and adding its callbacks, and can begin to
+ interact with the Flash file.
+
+ To generate your SWF files, use the ant task
+ "buildFlash". You must have the open source Motion Twin ActionScript
+ compiler (mtasc) installed and in your path to use the "buildFlash"
+ ant task; download and install mtasc from http://www.mtasc.org/.
+
+
+
+ buildFlash usage:
+
+ ant buildFlash -Ddojo.flash.file=../tests/flash/HelloWorld.as
+
+ where "dojo.flash.file" is the relative path to your Flash
+ ActionScript file.
+
+ This will generate two SWF files, one ending in _flash6.swf and the other
+ ending in _flash8.swf in the same directory as your ActionScript method:
+
+ HelloWorld_flash6.swf
+ HelloWorld_flash8.swf
+
+ Initialize dojo.flash with the filename and Flash communication version to
+ use during page load; see the documentation for dojo.flash for details:
+
+ dojo.flash.setSwf({flash6: "tests/flash/HelloWorld_flash6.swf",
+ flash8: "tests/flash/HelloWorld_flash8.swf"});
+
+ Now, your Flash methods can be called from JavaScript as if they are native
+ Flash methods, mirrored exactly on the JavaScript side:
+
+ dojo.flash.comm.sayHello();
+
+ Only Strings are supported being passed back and forth currently.
+
+ JavaScript to Flash communication is synchronous; i.e., results are returned
+ directly from the method call:
+
+ var results = dojo.flash.comm.sayHello();
+
+ Flash to JavaScript communication is asynchronous due to limitations in
+ the underlying technologies; you must use a results callback to handle
+ results returned by JavaScript in your Flash AS files:
+
+ var resultsReady = function(results){
+ trace("Received the following results from JavaScript: " + results);
+ }
+ DojoExternalInterface.call("someJavaScriptMethod", resultsReady);
+
+
+
+ -------------------
+ Notes
+ -------------------
+
+ If you have both Flash 6 and Flash 8 versions of your file:
+
+ dojo.flash.setSwf({flash6: "tests/flash/HelloWorld_flash6.swf",
+ flash8: "tests/flash/HelloWorld_flash8.swf"});
+
+ but want to force the browser to use a certain version of Flash for
+ all platforms (for testing, for example), use the djConfig
+ variable 'forceFlashComm' with the version number to force:
+
+ var djConfig = { forceFlashComm: 6 };
+
+ Two values are currently supported, 6 and 8, for the two styles of
+ communication described above. Just because you force dojo.flash
+ to use a particular communication style is no guarantee that it will
+ work; for example, Flash 8 communication doesn't work in Internet
+ Explorer due to bugs in Flash, and Flash 6 communication does not work
+ in Safari. It is best to let dojo.flash determine the best communication
+ mechanism, and to use the value above only for debugging the dojo.flash
+ framework itself.
+
+ Also note that dojo.flash can currently only work with one Flash object
+ on the page; it and the API do not yet support multiple Flash objects on
+ the same page.
+
+ We use some special tricks to get decent, linear performance
+ out of Flash 8's ExternalInterface on Safari; see the blog
+ post
+ http://codinginparadise.org/weblog/2006/02/how-to-speed-up-flash-8s.html
+ for details.
+
+ Your code can detect whether the Flash player is installing or having
+ its version revved in two ways. First, if dojo.flash detects that
+ Flash installation needs to occur, it sets dojo.flash.info.installing
+ to true. Second, you can detect if installation is necessary with the
+ following callback:
+
+ dojo.event.connect(dojo.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.
+
+ Two utility methods exist if you want to add loading and installing
+ listeners without creating dependencies on dojo.event; these are
+ 'addLoadingListener' and 'addInstallingListener'.
+
+ -------------------
+ Todo/Known Issues
+ -------------------
+
+ There are several tasks I was not able to do, or did not need to fix
+ to get dojo.storage out:
+
+ * When using Flash 8 communication, Flash method calls to JavaScript
+ are not working properly; serialization might also be broken for certain
+ invalid characters when it is Flash invoking JavaScript methods.
+ The Flash side needs to have more sophisticated serialization/
+ deserialization mechanisms like JavaScript currently has. The
+ test_flash2.html unit tests should also be updated to have much more
+ sophisticated Flash to JavaScript unit tests, including large
+ amounts of data.
+
+ * 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 dojo.flash subsystem.
