  • Google a-t-il raté son entrée sur le marché des tablettes ? Android connaît une "croissance pénible" d'après DisplaySearch

    Google a-t-il raté son entrée sur le marché des tablettes ? Android connaît une "croissance pénible" d'après DisplaySearch Six mois après le lancement d'Android 3 (alias Honeycomb), force est de constater que les ventes des tablettes qui tournent dessus sont loin de défrayer les chroniques, elles ne semblent pas être en mesure en tout cas de freiner les ventes frénétiques de l'iPad d'Apple. Pour l'analyste Richard Shim de DisplaySearch, l'univers Android connaît une « croissance pénible » avec Honeycomb : « il est clair que les premières tablettes fondées sur Android ne s'écoulent pas aussi bien que ce que beaucoup attendaient, quelques marques avec lesquelles ...

  • how to embed pure as3 bitmap assets with flex4 (worked with flex3)

    - by jedierikb
    In Flex3, I could compile pure as3 code and use "embed" tags to load in images. This was done by Flex making a BitmapAsset class. I can still do this in Flex4. However, there was a trick to fakeout flex3 and use my own mx.core.BitmapAsset class to remove some of the extraneous stuff Flex's BitmapAsset brings in with it. This is described here: http://www.ultrashock.com/forums/flex/embed-flex-assets-without-using-flex-123405.html Unfortunately, I cannot get these tricks to work with Flex4 and get smaller file sizes. I end up with the error "VerifyError: Error #1014: Class mx.core::BitmapAsset could not be found." This error leads me to this forum, and a solution as described there: http://tech.groups.yahoo.com/group/flexcoders/message/148762 Following this advice, I add -static-link-runtime-shared-libraries=true, and my swf loads without an error... but this means I am loading in the pieces of the flex framework I wanted to omit (and the file size says so too). Is there a better way to fake out flex4 when it comes to using Embed?

  • flex tabnavigator skin flicker

    - by Proyb2
    I am try to skin my tabnavigator with PNG, and extend with TabSkin.as and SelectedTabSkin.as, however, when I tried to mouseover, it will caused a flicker into black and load the tab image which I define. What can I do to avoid flicker? TabSkin.as same as SelectedTabSkin.as but different image package { import mx.controls.Image; public class TabSkin extends Image { public function TabSkin():void { super(); } override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); } } } Tab.MXML TabNavigator { tabHeight: 39; tab-width: 108; tabOffset: 1; tabStyleName: "tab"; } .tab { fillColors: #000000, #000000; up-skin: ClassReference("TabSkin"); down-skin: ClassReference("TabSkin"); over-skin: ClassReference("TabSkin"); selected-up-skin: ClassReference("SelectedTabSkin"); selected-down-skin: ClassReference("SelectedTabSkin"); selected-over-skin: ClassReference("SelectedTabSkin"); } .selectedTab { font-weight: bold; corner-radius: 0; } <mx:TabNavigator x="223" y="82" width="100%" height="100%" id="tab2"/>

  • Flex: How to refresh/repaint a chart?

    - by Rob
    I have a chart for which the data is provided asynchronously via a CallResponder (used with a RemoteObject). However, it does not seem possible to update the chart with the data after it has been initially drawn. Here are the relevant snippets of (simplified) code: // code below is in the application MXML <mx:CallResponder id="result" result="resultHandler(event)" /> private function resultHandler(event:ResultEvent):void { // panel is an instance of ChartPanel this.panel.init(event.result); } // invoked when user clicks a button private function displayChart():void { this.currentState = "ShowChart"; result.token = remoteObject.getUrlStatistics(); } // code below is in ChartPanel <mx:BarChart id="chart" /> public function init(value:Object):void { var xml:XMLList = XMLList(value); var data:ArrayCollection = new ArrayCollection(); for each (var element:XML in xml.children()) { // not shown: extract value out of XML, put in ArrayList data.addItem(...); } this.chart.dataProvider = data; } The result is that it draws an empty chart. the resultHandler function or init function in ChartPanel needs to trigger a repaint or something similar. I have tried: Firing a collection modified event after assigning it to chart.dataProvider calling invalidateDisplayList (tried with all components) binding the chart data provider to a variable, and doing the above. changing the view state on the last line of resultHandler. None of them worked. When I fetch the data and cache it locally, then use it to call init synchronously, the chart displays correctly. What am I missing here?

  • Setting up multiple channel types (AMF/AMFX) for Flex/BlazeDs

    - by Fergal
    We've configured our Flex client to have two channels for calling our services via BlazeDS. One channel is configured to use AMFChannel and the other for HTTPChannel. Here's the services-config.xml <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/data/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint" /> <properties> <polling-enabled>false</polling-enabled> </properties> </channel-definition> <channel-definition id="my-amfx" class="mx.messaging.channels.HTTPChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/data/messagebroker/amfx" class="flex.messaging.endpoints.HTTPEndpoint" /> <properties> <polling-enabled>false</polling-enabled> </properties> </channel-definition> Our flex client is written to use either AMF or AMFX depending on how we configure it. The problem is that although the client can switch between channels it sends an AMF binary payload when attempting to call services via AMFX (expecting XML). The funny thing is that we can write services-config.xml to use either AMF or AMFX individually but Flex doesn't seem to want to let us use both. Is this a bug in Flex? If not how can we get it to use the correct protocol?

  • Flex: FileReference and Image unhandled IOErrorEvent

    - by deux11
    The following code shows a button that allows you to select a file (should be an image) and display it into an image component. When I select an invalid image (e.g. a word document), I get the following error: "Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type." I know I can pass a FileFilter to the FileReference:browse call, but that's beyond the point. My question is... I want to handle the IOErrorEvent myself, what event listener am I missing? private var file:FileReference = new FileReference(); private function onBrowse():void { file.browse(null); file.addEventListener(Event.SELECT, handleFileSelect); file.addEventListener(Event.COMPLETE, handleFileComplete); } private function handleFileSelect(event:Event):void { file.load(); } private function handleFileComplete(event:Event):void { myImage.source = file.data; } private function handleImageIoError(evt:IOErrorEvent):void { Alert.show("IOErrorEvent"); } <mx:Button click="onBrowse()" label="Browse"/> <mx:Image id="myImage" width="100" height="100" ioError="handleImageIoError(event)"/>

  • Flex: embedded fonts not being applied correctly in Label and DataGrid

    - by lje
    Folks, I am observing a problem with how an embedded font is applied to certain Flex components, namely mx:Label and mx:DataGrid. I have a CSS that declares three variations on an embedded font as follows: @font-face { src:url("buttons.swf"); font-family: "Arial"; } @font-face { src:url("buttons.swf"); font-family: "Arial"; font-weight: bold; } @font-face { src:url("buttons.swf"); font-family: "Arial"; font-style: italic; } And in the style declaration for Label and DataGrid, I have: Label { fontFamily: "Arial"; fontSize: 11; fontFamily: LucidaSans; } and DataGrid { fontFamily: "Arial"; height: 16; } (I've snipped some stuff from both style rules, so if you think there's something that may be causing a conflict I can certainly post the entire definition. It's mostly color, line and padding stuff for the DataGrid.) The problem that is for both Label and cells in the DataGrid the text is being rendered as sort of a times new roman font. The headers in the DataGrid are fine, just the text in the cells is wonky. All other components use the correct font as defined in the CSS/SWF. Any ideas why this is happening?

  • Exponential regression : p-value and F significance

    - by Saravanan K
    I am new to statistics. I have a set of independent data and dependent data (X,Y), where I would like to do an exponential regression to obtain its p-value and significant F (already obtained R2 and also the coefficients through mathematical calculation). What is the natural evolution from the (X,Y) data to mathematically calculate those variables. Spent a week on the internet to study this but unable to find the right answer. Often an exponential data, y=be^(mx) will be converted first to a linear data, ln y = mx + ln b . Then a linear regression will done on the converted data, obtaining its p-value etc. Assume we use a statistical tool such as Excel's Analysis ToolPak: Data Analysis : Regression, it will produce a result such as below, I believe the p-value and Significant F value is representing the converted linear data and not the original exponential data. Questions: What is the approach/steps used by Excel to get the p-value and Significant F value for the converted linear data as shown in the statistic output in the image above? It is not clear in their help page or website. Can the p-value and Significant F could be mathematically calculated for exponential regression without using a statistical tool? Can you assist to point me to the right link if this has been answered before.

  • Creating a framework for ASP.NET web forms similar to Flex states.

    - by Shawn Simon
    I really enjoy the flex states framework. You define a few states for your control, and then can set child controls to only appear in certain states. Check out this code: <s:states> <s:State name="signin"/> <s:State name="register"/> </s:states> <mx:FormItem label="Last name:" includeIn="register" id="lastNameItem" alpha="0.0"> <s:TextInput id="lastName" width="220"/> </mx:FormItem> Now the last name form will only appear in the register screen. This would be really useful I think in .NET where you use the page for views like update / insert. I was considering extending the Page element to have a states property using extension methods, and adding the include in to controls. This way I could auto-hide controls based on the current view at render time. What is even cooler in Flex, is that you can use different handlers / properties based on the current state. <s:Button label="Sign in" label.register="Register" id="loginButton" enabled="true" click.signin="signin()" click.register="register()"/> I'm sure there's a way I could implement something similar to this as well. Do you think this is a good idea? Or does it just add a level of abstraction to framework that already has a poor separation of concerns?

  • Run a flash movie in flex application.

    - by Irwin
    I've a flash movie that I would like to use inside of a flex application, very similar to a preloader. Looking at this tutorial, http://www.flexer.info/2008/02/07/very-first-flex-preloader-customization/, I expected it would be a matter of not extending "Preloader" and extending "Sprite" and using the class i created wherever i needed. Alas, the movie I created, is not being shown. This is the code for my class containing the movie, made based on the tutorial above: package { import mx.preloaders.DownloadProgressBar; import flash.display.Sprite; import flash.events.ProgressEvent; import flash.events.Event; import mx.events.FlexEvent; import flash.display.MovieClip; public class PlayerAnimation extends Sprite { [Embed("Player.swf")] public var PlayerGraphic:Class; public var mc:MovieClip; public function PlayerAnimation():void { super(); mc = new PlayerGraphic(); addChild(mc); } public function Play():void { mc.gotoAndStop(2); } } }

  • How to add namespaces to a flex AIR project in Flash Builder 4?

  • Flex/Actionscript image display problem.

    - by IanH
    I'm trying to extend the Image class but hit a problem that I can't get past. I have a private image (img) that loads an image and a function that takes that image and copies it onto the parent. The debug function "copyit2" displays the image fine (so I know it's loaded OK). But the function "copyit" doesn't work - it just displays a white rectangle. I can't see how to make copyit work so that the original image is copied to the BitmapData and then subsequenty copied onto the parent? (The idea is to do some processing on the Bitmap data before it is displayed, although this isn't shown here to keep the example simple.) I suspect it is something to do with the security of loading images, but I'm loading it from the same server as the application is run from - so this shouldn't be a problem? Thanks for any help anyone can provide. Ian package zoomapackage { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Sprite; import flash.events.MouseEvent; import flash.geom.Matrix; import flash.geom.Point; import flash.geom.Rectangle; import flash.net.*; import mx.controls.Image; import mx.events.FlexEvent; public dynamic class Zooma extends Image { private var img:Image; public function copyit():void { var imgObj:BitmapData = new BitmapData(img.content.width, img.content.height, false); imgObj.draw(img); var matrix:Matrix = new Matrix(); this.graphics.beginBitmapFill(imgObj, matrix, false,true); this.graphics.drawRect(0, 0, this.width , this.height); this.graphics.endFill(); } public function copyit2():void { this.source = img.source; } public function Zooma() { super(); img = new Image(); img.load("http://localhost/Koala.jpg"); } } }

  • flex 4 release changes to application are not showing up.

    - by guacamoly
    I just took over a clients flex project and I can't get the app to reflect even a simple trace statement. Before I took over, the project was last successfully built using the Flash Builder Beta 2 environment/sdk. I have the latest release version of Flash Builder 4. Upon importing the project into FB4, I got a ton of errors. Most of them mostly because of the changes made to the sdk from beta2 to release. Some of the things I corrected: - mx namespace from library://ns.adobe.com/flex/halo to library://ns.adobe.com/flex/mx - video player skinning: a lot of the state names for the video player component had been changed, more required states had been added. also there were other video related component and property names that had to be updated. But I fixed all that and the application was finally able to compile (although with some warnings mostly of the duplicate variable type) The only thing now is that whatever change I make to the project doesn't get reflected in the build (debug or release). I changed existing traces, added additional traces. Nothing shows up. I even removed the applicationComplete property in the main.mxml. Everything still ran like nothing changed. Also I can't seem to debug the app. Whenever I try to debug.. flash builder says.. "Swf Application doesn't contain the required debugging information ... " Anyone have any idea how I need to even begin tackling all this? Any help or pointers would be greatly appreciated.

But, there are two problems, first, when slope approaches infinity the range of what the L1Sensor1 should "react" to (it "reacts" by changing its image) becomes smaller. Also, the code that should handle infinity is not working. Thanks for the help in advanced.

If I try to execute it via JMX using a proxy object, I get an Exception: Caused by: javax.management.ReflectionException at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:231) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:668) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) Caused by: java.lang.IllegalArgumentException: Unable to find operation updateProperties(java.util.HashMap) It appears that it attempts to use the actual implementation class rather than the interface, and doesn't check if this is a child of the required interface. The same thing happens for extended classes (for example declare HashMap, pass in LinkedHashMap). Does this mean it's impossible to use an interface for such methods? At the moment I'm getting around it by changing the method signature to accept a HashMap, but it seems odd that I wouldn't be able to use interfaces (or extended classes) in my MBeans. Edit: The proxy object is being created by an in-house utility class called JmxInvocationHandler. The (hopefully) relevant parts of it are as follows: public class JmxInvocationHandler implements InvocationHandler { ... public static <T> T createMBean(final Class<T> iface, SFSTestProperties properties, String mbean, int shHostID) { T newProxyInstance = (T) Proxy.newProxyInstance(iface.getClassLoader(), new Class[] { iface }, (InvocationHandler) new JmxInvocationHandler(properties, mbean, shHostID)); return newProxyInstance; } ... private JmxInvocationHandler(SFSTestProperties properties, String mbean, int shHostID) { this.mbeanName = mbean + MBEAN_SUFFIX + shHostID; msConfig = new MsConfiguration(properties.getHost(0), properties.getMSAdminPort(), properties.getMSUser(), properties.getMSPassword()); } ... public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { if (management == null) { management = ManagementClientStore.getInstance().getManagementClient(msConfig.getHost(), msConfig.getAdminPort(), msConfig.getUser(), msConfig.getPassword(), false); } final Object result = management.methodCall(mbeanName, method.getName(), args == null? new Object[] {} : args); return result; } }

  • Flex Tree Properties, Null Reference?

    - by mvrak
    I am pulling down a large XML file and I have no control over it's structure. I used a custom function to use the tag name to view the tree structure as a flex tree, but then it breaks. I am guessing it has something to do with my other function, one that calls attribute values from the selected node. See code. <mx:Tree x="254" y="21" width="498" height="579" id="xmllisttree" labelFunction="namer" dataProvider="{treeData}" showRoot="false" change="treeChanged(event)" /> //and the Cdata import mx.rpc.events.ResultEvent; [Bindable] private var fullXML:XMLList; private function contentHandler(evt:ResultEvent):void{ fullXML = evt.result.page; } [Bindable] public var selectedNode:Object; public function treeChanged(event:Event):void { selectedNode=Tree(event.target).selectedItem; } public function namer(item:Object):String { var node:XML = XML(item); var nodeName:QName = node.name(); var stringtest:String ="bunny"; return nodeName.localName; } The error is TypeError: Error #1009: Cannot access a property or method of a null object reference. Where is the null reference?

  • flex using tweenmax library

    - by Nishant
    Hello, I am currently using flex transition effects on state change. Is there a way I can use tweenmax library for that? Update: In the code below, I have transitions from state one to state two. I would like to replace that code tweenermax library. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <s:states> <s:State name="one" /> <s:State name="two" /> </s:states> <s:transitions> <s:Transition fromState="one" toState="two"> <s:Parallel targets="{one, two}"> <s:Fade /> </s:Parallel> </s:Transition> <s:Transition fromState="two" toState="one"> <s:Parallel targets="{one, two}"> <s:Fade /> </s:Parallel> </s:Transition> </s:transitions> <component:one id="one" /> <component:one id="two" /> </s:Application>

  • Need some help setting up subdomains for my site

    - by KarimSaNet
    I'm setting up my website and want to have it so all subdomain requests are rewritten to the appropriate subdirectory. For example http://projects.karimsa.net/ -> http://karimsa.net/projects/ But I want to use the Apache rewrite mod to do this so that the URL in the browser stays the same. Here is what my config looks like at the moment: ## rewrite subdomains RewriteEngine On RewriteCond %{HTTP_HOST} ^(.*).karimsa.net RewriteCond %{HTTP_HOST} !^www.karimsa.net [NC] RewriteRule ^(.*)$ http://karimsa.net/%1/$1 [R=301,L] And my CNAME records on 'projects.karimsa.net': Domain TTL Data Type projects.karimsa.net 14400 karimsa.net CNAME Theoretically, I feel this should work. But when I go to the URL, it gives me a server misconfiguration error, my provider's default webpage. What I should see is the index.php under /projects/. What am I doing wrong? Any help would be appreciated, thanks for reading. Addition: I realized I forgot to mention some of the problem. The domain 'karimsa.net' is parked at 'karimsa.x10.mx'. If I set up the same configuration on 'projects.karimsa.x10.mx', the rewrite and CNAME work. But on the parked domain I still get the default webpage.
