  • jquery plugin caroufredsel hide next/prev buttons until mouseover carousel

    - by John Magnolia
    I am trying to make the buttons hide by default and they only become visible when the mouse is over. Although I am having problems where the carousel core code seems to be adding display block even if I set display none in the CSS. var $slides = $("#slides"); $slides.find('ul.banners').eq(0).carouFredSel({ height: 360, items: { visible: 1 }, scroll: { easing: "easeInOutSine", duration: 1200 }, auto: { delay: 1000 }, prev: { button: $slides.find('.prev'), items: 1 }, next:{ button: $slides.find('.next'), items: 1 }, pagination: { container: $slides.find(".pagination"), keys: true, anchorBuilder: function(nr) { return '<li><a href="#"><span>'+nr+'</span></a></li>'; } } }); $slideButtons = $slides.find(".next,.prev"); $slides.find('ul.banners').hover(function(){ $slideButtons.fadeIn(); },function(){ $slideButtons.fadeOut(); }); HTML <div id="slides"> <ul class="banners"> <li><img /></li> <li><img /></li> </ul> <ul class="pagination"></ul> <div class="next">Next</div> <div class="prev">Previous</div> </div>

  • How to catch YouTube embed code and turn into URL

    - by Jonathan Vanasco
    I need to strip YouTube embed codes down to their URL only. This is the exact opposite of all but one question on StackOverflow. Most people want to turn the URL into an embed code. This question addresses the usage patttern I want, but is tied to a specific embed code's regex ( Strip YouTube Embed Code Down to URL Only ) I'm not familiar with how YouTube has offered embeds over the years - or how the sizes differ. According to their current site, there are 2 possible embed templates and a variety of options. If that's it, I can handle a regex myself -- but I was hoping someone had more knowledge they could share, so I could write a proper regex pattern that matches them all and not run into endless edge-cases. The full use case scenario : user enters content in web based wysiwig editor backend cleans out youtube & other embed codes; reformats approved embeds into an internal format as the text is all converted to markdown. on display, appropriate current template/code display for youtube or other 3rd party site is generated At a previous company, our tech-team devised a plan where YouTube videos were embedded by listing the URL only. That worked great , but it was in a CMS where everyone was trained. I'm trying to create a similar storage, but for user-generated-content.

  • PHP does not store all variables in session

    - by Flurin Juvalta
    Dear all I'm assigning session variables by filling the $_SESSION - Array throughout my script. My problem is, that for some reason not all variables are available in the session. here is a shortened version of my code for explaining this issue: session_start(); print_r($_SESSION); $_SESSION['lang'] = 'de'; $_SESSION['location_id'] = 11; $_SESSION['region_id'] = 1; $_SESSION['userid'] = 'eccbc87e4b5ce2fe28308fd9f2a7baf3'; $_SESSION['hash'] = 'dce57f1e3bc6fba32afab93b0c38b662'; print_r($_SESSION); first call prints something like this: Array ( ) Array ( [lang] => de [location_id] => 11 [region_id] => 1 [userid] => eccbc87e4b5ce2fe28308fd9f2a7baf3 [hash] => dce57f1e3bc6fba32afab93b0c38b662 ) the second call prints: Array ( [lang] => de [location_id] => 11 [region_id] => 1 ) Array ( [lang] => de [location_id] => 11 [region_id] => 1 [userid] => eccbc87e4b5ce2fe28308fd9f2a7baf3 [hash] => dce57f1e3bc6fba32afab93b0c38b662 ) As you can see, the important login information is not stored in the session. Does anybody has an idea what could be wrong with my session? Thanks for your answers!

  • Accessing Element Count and Values Within a Hidden Div

    - by Tegan Snyder
    I'm having trouble grabbing the TR count in JQuery of a table that inside a DIV set to be hidden. Here is an example: <div id="questions" style="display: none;"> <table id="tbl_questions"> <thead> <tr> <th>Question</th> <th>Weight</th> </tr> </thead> <tbody> <tr id="q0"> <td id="td_question0">Some Question 0</td> <td id="td_wieght0">Some Weight 0</td> </tr> <tr id="q1"> <td id="td_question1">Some Question 1</td> <td id="td_wieght1">Some Weight 1</td> </tr> </tbody> </table> </div> Note the table is within the containing div. It's set to display: none. When I try to run this JQuery code it returns 0. var question_count = $("#tbl_questions> tr").size(); alert(question_count); Any ideas? I'm try to locate the count so I can then build an array of each question and weight in the table. Since the ID's provide me with an index this should be simple, but is the fact that it is contained in a hidden DIV going to be a problem just as the above question? Thanks, Tegan Snyder

  • HTML5 audio object doesn't play on iPad (when called from a setTimeout)

    - by Dan Halliday
    I have a page with a hidden <audio> object which is being started and stopped using a custom button via javascript. (The reason being I want to customise the button, and that drawing an audio player seems to destroy rendering performance on iPad anyway). A simplified example (in coffeescript): // Works fine on all browsers constructor: (@_button, @_audio) -> @_button.on 'click', @_play // Bind button's click event with jQuery _play: (e) => @_audio[0].play() // Call play() on audio element The audio plays fine when triggered from a function bound to a click event, but I actually want an animation to complete before the file plays so I put .play() inside a setTimeout. However I just can't get this to work: // Will not play on iPad constructor: (@_button, @_audio) -> @_button.on 'click', @_play // Bind button's click event with jQuery _play: (e) => setTimeout (=> // Declare a 300ms timeout @_audio[0].play() // Call play() on audio element ), 300 I've checked that @_audio (this._audio) is in scope and that its play() method exists. Why doesn't this work on iPad?

  • jQuery validation with submit handler

    - by James
    I setup the form validation using jQuery validation plug-in's validate method and I have a submit handler that modifies the input element's value (I use YUI editor and it needs saveHTML() call to copy the iframe's content to the textarea element.). When submitting the form, I want the validator to validate the form after executing my submit handler. But it doesn't execute my submit handler if it is registered after the validate call. For example, <form id="form1" action="/test"> <input type="text" name="txt1" id="txt1" /> <input type="submit" value="submit" /> $(document).ready(function() { $("#form1").submit(function() { $("#txt1").val("123456"); }); $("#form1").validate({ rules: { txt1: { maxlength: 5 } } }); }); The form is validated after my submit handler so submit is canceled. $(document).ready(function() { $("#form1").validate({ rules: { txt1: { maxlength: 5 } } }); $("#form1").submit(function() { $("#txt1").val("123456"); }); }); However if I change the order the form is validated before my submit handler.

  • Python calling class methods with the wrong number of parameters

    - by Hussain
    I'm just beginning to learn python. I wrote an example script to test OOP in python, but something very odd has happened. When I call a class method, Python is calling the function with one more parameter than given. Here is the code: 1. class Bar: 2. num1,num2 = 0,0 3. def __init__(num1,num2): 4. num1,num2 = num1,num2 5. def foo(): 6. if num1 num2: 7. print num1,'is greater than ',num2,'!' 8. elif num1 is num2: 9. print num1,' is equal to ',num2,'!' 10. else: 11. print num1,' is less than ',num2,'!' 12. a,b,t = 42,84,bar(a,b) 13. t.foo 14. 15. t.num1 = t.num1^t.num2 16. t.num2 = t.num2^t.num1 17. t.num1 = t.num1^t.num2 18. 19. t.foo 20. And the error message I get: python test.py Traceback (most recent call last): File "test.py", line 12, in a,b,t = 42,84,bar(a,b) NameError: name 'bar' is not defined Can anyone help?

  • SWIG interface to receive an opaque struct reference in Java through function argument

    - by Beeo
    I am trying to use SWIG in order to use the Spotify API (libspotify) for Android: https://developer.spotify.com/technologies/libspotify/ I am having trouble defining the SWIG interface file to be able to successfully call the following native C function: sp_error sp_session_create(const sp_session_config * config, sp_session ** sess); Which in C would be called like this: //config struct defined previously sp_session *sess; sp_session_create(&config, &sess); But in Java I would need to call it like this: //config object defined previously sp_session javaSess = new sp_session(); sp_session_create(config, javaSess); sp_session is an opaque struct and is only defined in libspotify's API.h file as: typedef struct sp_session sp_session; I'm expecting the libspotify library to create it and give me a reference to it. The only thing I need that reference for then is to pass to other functions in the API. I believe the answer lies within the SWIG interface and typemaps, but I have been unsuccessful in trying to apply the examples I found in the documentation: http://www.swig.org/Doc2.0/SWIGDocumentation.html#Java_struct_pointer_pointer `http://www.swig.org/Doc2.0/SWIGDocumentation.html#Java_using_typemaps_return_arguments Help!

  • Why is this linq extension method hit the database twice?

    - by Pure.Krome
    Hi folks, I have an extension method called ToListIfNotNullOrEmpty(), which is hitting the DB twice, instead of once. The first time it returns one result, the second time it returns all the correct results. I'm pretty sure the first time it hits the database, is when the .Any() method is getting called. here's the code. public static IList<T> ToListIfNotNullOrEmpty<T>(this IEnumerable<T> value) { if (value.IsNullOrEmpty()) { return null; } if (value is IList<T>) { return (value as IList<T>); } return new List<T>(value); } public static bool IsNullOrEmpty<T>(this IEnumerable<T> value) { if (value != null) { return !value.Any(); } return true; } I'm hoping to refactor it so that, before the .Any() method is called, it actually enumerates through the entire list. If i do the following, only one DB call is made, because the list is already enumerated. var pewPew = (from x in whatever select x) .ToList() // This enumerates. .ToListIsNotNullOrEmpty(); // This checks the enumerated result. I sorta don't really want to call ToList() then my extension method. Any ideas, folks?

  • [C#] Three System.Drawing methods manifest slow drawing or flickery: Solutions? or Other Options?

    - by Luke Mcneice
    Hi all, I am doing a little graphing via the System.Drawing and im having a few problems. I'm holding data in a Queue and i'm drawing(graphing) out that data onto three picture boxes this method fills the picture box then scrolls the graph across. so not to draw on top of the previous drawings (and graduly looking messier) i found 2 solutions to draw the graph. Call plot.Clear(BACKGOUNDCOLOR) before the draw loop [block commented] although this causes a flicker to appear from the time it takes to do the actual drawing loop. call plot.DrawLine(channelPen[5], j, 140, j, 0); just before each drawline [commented] although this causes the drawing to start ok then slow down very quickly to a crawl as if a wait command had been placed before the draw command. Here is the Code for reference: /*plotx.Clear(BACKGOUNDCOLOR) ploty.Clear(BACKGOUNDCOLOR) plotz.Clear(BACKGOUNDCOLOR)*/ for (int j = 1; j < 599; j++) { if (j > RealTimeBuffer.Count - 1) break; QueueEntity past = RealTimeBuffer.ElementAt(j - 1); QueueEntity current = RealTimeBuffer.ElementAt(j); if (j == 1) { //plotx.DrawLine(channelPen[5], 0, 140, 0, 0); //ploty.DrawLine(channelPen[5], 0, 140, 0, 0); //plotz.DrawLine(channelPen[5], 0, 140, 0, 0); } //plotx.DrawLine(channelPen[5], j, 140, j, 0); plotx.DrawLine(channelPen[0], j - 1, (((past.accdata.X - 0x7FFF) / 256) + 64), j, (((current.accdata.X - 0x7FFF) / 256) + 64)); //ploty.DrawLine(channelPen[5], j, 140, j, 0); ploty.DrawLine(channelPen[1], j - 1, (((past.accdata.Y - 0x7FFF) / 256) + 64), j, (((current.accdata.Y - 0x7FFF) / 256) + 64)); //plotz.DrawLine(markerPen, j, 140, j, 0); plotz.DrawLine(channelPen[2], j - 1, (((past.accdata.Z - 0x7FFF) / 256) + 94), j, (((current.accdata.Z - 0x7FFF) / 256) + 94)); } Is there any tricks to avoid these overheads? If not would there be any other/better solutions?

  • Hyperlink in Silverlight AccordionItem HeaderTemplate

    - by Charlie Brown
    I have created a HeaderTemplate for my accordions where I want to display a text block on one side of the header and a hyperlink on the right side. The display is working correctly, but the click event is not called when the user clicks, I'm guessing b/c the header itself is trapping the click for expand/contract. <layoutToolkit:Accordion> <layoutToolkit:AccordionItem IsSelected="True"> <layoutToolkit:AccordionItem.HeaderTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="20"> <TextBlock Margin="0,0,700,0">Cancel Postcards</TextBlock> <HyperlinkButton Content="Next Call" Foreground="Blue" Click="NextCancel_Click" /> </StackPanel> </DataTemplate> </layoutToolkit:AccordionItem.HeaderTemplate> ..... more code .... Is there a way to get the hyperlink to respond to events without practically creating a new control?

  • Windows/C++: how to use a COM dll which is not registered

    - by Albert
    Hi, In our application, we need to use a COM dll (namely msdia100.dll) which was not registered in the system before. Earler, we have just called the DLL by calling its DllRegisterServer via this code: // Register DIA DLL required by Breakpad std::string diaLibPath = "msdia100"; HMODULE diaLib = LoadLibrary(diaLibPath.c_str()); if( diaLib == NULL ) { errors << "Cannot load DLL " << diaLibPath << endl; return; } typedef HRESULT ( __stdcall * regServer_t )(void); regServer_t regServer = (regServer_t)GetProcAddress(diaLib, "DllRegisterServer"); if( regServer == NULL ) { errors << "Cannot get method DllRegisterServer from " << diaLibPath << endl; FreeLibrary(diaLib); return; } if( regServer() != S_OK ) { errors << "Cannot call DllRegisterServer from " << diaLibPath << endl; } FreeLibrary(diaLib); This doesn't work anymore on Windows 7 (maybe also Vista, didn't tried) because to call this function, it needs Administrator privileges. All solutions to this problem I have found where about getting those Admin rights. That is no possible solution for us because our application must also work if the user is not able to get those Admin rights. It is also no solution for us to suddenly need an installer for our application which registeres this DLL. So, what possibilities are there? How can I use this DLL without Admin rights? Do I have to recode COM which works without the need to register a DLL first?

This works fine for me, the Timertask gets all the data I want from the database... Before this TimerTask is triggered I want to "lock" the screen for some seconds that no user(session scoped) can access the database(this I also know how this will work) ... My problem is that I don't know/ cannot find a way/ i am to stupid to call a dialog programatically ... Any tips, hints would be very cool :) Thanks a lot ! UPDATE: I want to set this primefaces dialog: Dialog dialog = new Dialog(); dialog.setAppendToBody(true); dialog.setModal(true); dialog.setVisible(true); dialog.setWidgetVar("generatedDialog"); dialog.setId("fancyDialog"); dialog.setClosable(false); dialog.setHeader("Getting latest information from the database"); dialog.setDynamic(true); dialog.setResizable(false); dialog.setDraggable(false); How can I do that ? :/ How do I display it to my browser ? :o Regards

  • php class scope when calling a non-method function not accessing all class members

    - by Aglystas
    So I'm using a stand alone function from within a class that that uses the class it's being called from. Here's the function function catalogProductLink($product_id,$product_name,$categories=true) { //This is the class that the function is called from global $STATE; if ($categories) { //The $STATE->category_id is the property I want to access, which I can't if (is_array($STATE->category_id)) { foreach($STATE->category_id as $cat_id) { if ($cat_id == 0) continue; $str .= "c$cat_id/"; } } } $str .= catalogUrlKeywords($product_name).'-p'.$product_id.'.html'; return $str; } And here's the function call, which is being made from within the $STATE class. $redirect = catalogProductLink($this->product_id, $tempProd->product_name, true, false); The object that I need access to is the $STATE object that has been declared global. Prior to this function call there are lots of public properties populated, but when I look at the $STATE object within the function scope it loses all the properties but one, product_id. The property that matters for this function is the category_id property, which is an array of category id's. I'm wondering why I don't have access to all the public properties of the $STATE object and how I can get access to them.

  • Deal with undefined values in code or in the template?

    - by David
    I'm writing a web application (in Python, not that it matters). One of the features is that people can leave comments on things. I have a class for comments, basically like so: class Comment: user = ... # other stuff where user is an instance of another class, class User: name = ... # other stuff And of course in my template, I have <div>${comment.user.name}</div> Problem: Let's say I allow people to post comments anonymously. In that case comment.user is None (undefined), and of course accessing comment.user.name is going to raise an error. What's the best way to deal with that? I see three possibilities: Use a conditional in the template to test for that case and display something different. This is the most versatile solution, since I can change the way anonymous comments are displayed to, say, "Posted anonymously" (instead of "Posted by ..."), but I've often been told that templates should be mindless display machines and not include logic like that. Also, other people might wind up writing alternate templates for the same application, and I feel like I should be making things as easy as possible for the template writer. Implement an accessor method for the user property of a Comment that returns a dummy user object when the real user is undefined. This dummy object would have user.name = 'Anonymous' or something like that and so the template could access it and print its name with no error. Put an actual record in my database corresponding to a user with user.name = Anonymous (or something like that), and just assign that user to any comment posted when nobody's logged in. I know I've seen some real-world systems that operate this way. (phpBB?) Is there a prevailing wisdom among people who write these sorts of systems about which of these (or some other solution) is the best? Any pitfalls I should watch out for if I go one way vs. another? Whoever gives the best explanation gets the checkmark.

  • OSMF seek with Amazon Cloudfront

    - by giorrrgio
    I've written a little OSMF player that streams via RTMP from Amazon Cloudfront. There's a known issue, the mp3 duration is not correctly readed from metadata and thus the seek function is not working. I know there's a workaround implying the use of getStreamLength function of NetConnection, which I successfully implemented in a previous non-OSMF player, but now I don't know how and when to call it, in terms of OSMF Events and Traits. This code is not working: protected function initApp():void { //the pointer to the media var resource:URLResource = new URLResource( STREAMING_PATH ); // Create a mediafactory instance mediaFactory = new DefaultMediaFactory(); //creates and sets the MediaElement (generic) with a resource and path element = mediaFactory.createMediaElement( resource ); var loadTrait:NetStreamLoadTrait = element.getTrait(MediaTraitType.LOAD) as NetStreamLoadTrait; loadTrait.addEventListener(LoaderEvent.LOAD_STATE_CHANGE, _onLoaded); player = new MediaPlayer( element ); //Marker 5: Add MediaPlayer listeners for media size and current time change player.addEventListener( DisplayObjectEvent.MEDIA_SIZE_CHANGE, _onSizeChange ); player.addEventListener( TimeEvent.CURRENT_TIME_CHANGE, _onProgress ); initControlBar(); } private function onGetStreamLength(result:Object):void { Alert.show("The stream length is " + result + " seconds"); duration = Number(result); } private function _onLoaded(e:LoaderEvent):void { if (e.newState == LoadState.READY) { var loadTrait:NetStreamLoadTrait = player.media.getTrait(MediaTraitType.LOAD) as NetStreamLoadTrait; if (loadTrait && loadTrait.netStream) { var responder:Responder = new Responder(onGetStreamLength); loadTrait.connection.call("getStreamLength", responder, STREAMING_PATH); } } }

  • Stuggling with webkit-transition in javascript

    - by Mungbeans
    I've tried a few variations of using webkit-transition that I've found from googling but I've not been able to get any to work. I have some audio controls that I make appear on a click event, they appear suddenly and jerky so I want to fade them in. The target browser is iOS so I am trying webkit extensions. This is what I currently have: <div id = "controls"> <audio id = "audio" controls></audio> </div> #controls { position:absolute; top: 35px; left:73px; height: 20px; width: 180px; display:none; } #audio { opacity:0.0; } audio.src = clip; audio.addEventListener('pause', onPauseOrStop, false); audio.addEventListener('ended', onPauseOrStop, false); audio.play(); audioControls.style.display = 'block'; audio.style.setProperty("-webkit-transition", "opacity 0.4s"); audio.style.opacity = 0.7; The documentation for webkit-transition says it takes effect on a change in the property, so I was assuming changing style.opacity in the last line would kick it off. The controls appear with an opacity of 0.7 but I want it to fade in and that animation isn't happening. I also tried this: #audio { opacity:0.0; -webkit-transition-property: opacity; -webkit-transition-duration: 1s; -webkit-timing-function: ease-in; } Also tried audio.style.webkitTransition = "opacity 1.4s"; from this posting How to set CSS3 transition using javascript? I can't get anything to work, I'm testing on iOS, Safari desktop and Chrome. Same non result on all of them.

  • Calling jQuery method from onClick attribute in HTML

    - by Russell
    I am relatively new to implementing JQuery throughout an entire system, and I am enjoying the opportunity. I have come across one issue I would love to find the correct resolve for. Here is a simple case example of what I want to do: I have a button on a page, and on the click event I want to call a jquery function I have defined. Here is the code I have used to define my method (Page.js): (function($) { $.fn.MessageBox = function(msg) { alert(msg); }; }); And here is my HTML page: <HTML> <head> <script type="text/javascript" src="C:\Sandpit\jQueryTest\jquery-1.3.2.js"></script> <script language="javascript" src="Page.js"></script> </head> <body> <div class="Title">Welcome!</div> <input type="button" value="ahaha" onclick="$().MessageBox('msg');" /> </body> </HTML> (The above code displays the button, but clicking does nothing.) I am aware I could add the click event in the document ready event, however it seems more maintainable to put events in the HTML element instead. However I have not found a way to do this. Is there a way to call a jquery function on a button element (or any input element)? Or is there a better way to do this? Thanks

  • Vertically Aligning Elements

    - by Naz
    I'm trying to understand how to center elements within a div. I have this basic code I am working with and am trying to get the 'This is a button' element to be in the center <body> <div style="width:960px;background-color:#d7d7d7;"> <div style=" width:400px; padding:10px; height:auto; background-color:#006699; display:inline-block; "> <p> Vivamus vel sapien. Praesent nisl tortor, laoreet eu, dapibus quis, egestas non, mauris. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Vivamus vel sapien. Praesent nisl tortor, laoreet eu, dapibus quis, egestas non, mauris. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.</p> </div> <div style=" width:100px; padding:10px; height:auto; background-color:#b1b1b1; float:right; display:inline-block; margin:auto!important; vertical-align:middle; "> <p>This is a button</p> </div> </div> </body> It's essentially 1 div, divided into 2 with text on the left hand side and a 'This is a button' label to be in the center of the right side, but I can;t figure out how to get it to center, I've tried all sorts of methods. All help/advice is appreciated.

  • How can I keep an event from being delivered to the GUI until my code finished running?

    - by Frerich Raabe
    I installed a global mouse hook function like this: mouseEventHook = ::SetWindowsHookEx( WH_MOUSE_LL, mouseEventHookFn, thisModule, 0 ); The hook function looks like this: RESULT CALLBACK mouseEventHookFn( int code, WPARAM wParam, LPARAM lParam ) { if ( code == HC_ACTION ) { PMSLLHOOKSTRUCT mi = (PMSLLHOOKSTRUCT)lParam; // .. do interesting stuff .. } return ::CallNextHookEx( mouseEventHook, code, wParam, lParam ); } Now, my problem is that I cannot control how long the 'do interesting stuff' part takes exactly. In particular, it might take longer than the LowLevelHooksTimeout defined in the Windows registry. This means that, at least on Windows XP, the system no longer delivers mouse events to my hook function. I'd like to avoid this, but at the same time I need the 'do interesting stuff' part to happen before the target GUI receives the event. I attempted to solve this by doing the 'interesting stuff' work in a separate thread so that the mouseEventHookFn above can post a message to the worker thread and then do a return 1; immediately (which ends the hook function but avoids that the event is handed to the GUI). The idea was that the worker thread, when finished, performs the CallNextHookEx call itself. However, this causes a crash inside of CallNextHookEx (in fact, the crash occurs inside an internal function called PhkNextValid. I assume it's not safe to call CallNextHookEx from outside a hook function, is this true? If so, does anybody else know how I can run code (which needs to interact with the GUI thread of an application) before the GUI receives the event and avoid that my hook function blocks too long?

  • Flash - Http service bound to a button can be used only once ?

    - by SAKIROGLU Koray
    I have a flex project, in one of the screen of my UI, I create a HTTP service that call a "doGet" J2EE servlet through the GET method; and I bind the service call to a button. The service print log to system.out so I know when it is run. The problem I have is, when I click said button the first time, the servlets do what it is supposed to do, and print the stack to system.out, but if I click another time, nothing happens. Any idea what might be the cause ? Here's the flex code (code and service has been generated by Eclipse flex plugin) <mx:Script> <![CDATA[ protected function button_clickHandler(event:MouseEvent):void { LaunchSimulResult.token = simulation.LaunchSimul(); } ]]> </mx:Script> <mx:Canvas> ... <mx:Button label="Simulation" id="button" click="button_clickHandler(event)"/> .. </mx:Canvas> <mx:CallResponder id="LaunchSimulResult"/> <simulation:Simulation id="simulation" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/>
