  • 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?

  • Flex4 Application state in a custom component

    - by itarato
    Hi, I'm porting my Flex3 app to Flex4 (FlashBuilder4). I get the whole new state concept, except one thing. In a custom component (separate mxml file) I'm using the main level Application's state. In Flex3 it was: <mx:State name="only_view_mode"> <mx:RemoveChild target="{myComponent.button1}" /> </mx:State> In Flex4 it should be something like that: <mx:State name="only_view_mode" /> and <mx:LinkButton id="button1" excludeFrom="???" /> My question is: how can I access to an Application state from a component? I checked the official reference (http://www.adobe.com/go/learn_flex4_alldocumentation_en) and Google of course but without any success. Thanks in advance

  • Making a mini paint area in AS3/Flex4

    - by Parris
    So below is the code I have so far. For now I simply want to make it draw a square and have it show up. Right now when I click the area defined in MXML as <components:PaintArea width="100%" height="100%" id="paint-a"></PaintArea> it shows nothing; however, the actionlistener is getting triggered and an element is being added to the group. Not sure exactly what is going on... perhaps for some reason it doesn't think the element is drawable? Anyways thanks for the help! public class PaintArea extends SkinnableContainer { private var canvas:Group; public function PaintArea() { super(); canvas = new Group(); canvas.clipAndEnableScrolling = true; canvas.percentHeight = 100; canvas.percentWidth = 100; canvas.addEventListener(MouseEvent.MOUSE_UP,drawRectangle); this.addElement(canvas); } private function drawRectangle(e:MouseEvent):void{ var r:Rect = new Rect(); r.fill = new SolidColor(0x00ff00,.5); canvas.addElement(r); } }

  • Advantages of Migrating Flex3 App to Flex4

    - by Srirangan
    Hi guys, What are the advantages of migrating a Flex 3 app (Java backend, BlazeDS, Spring, Hibernate) to Flex 4? One of the biggest advantages of Flex 4 is design. Assuming that design / UI isn't a big driver for the business right now as compared to performance, what are the other factors we can highlight? We have implemented Cairngorm and Swiz on the App (with a gradual "roll out" of Cairngorm planned for the future). Any opinions? Thanks, Sri

  • Can't create flex4 project in flexbuilder using remoting or LiveCycle Data Servcies ES

    - by anopres
    I'm trying out the FlasBuilder ide with ColdFusion 8 on OS X. When I try to create a new project, I get stuck at the server setup screen that forces you to validate your paths for your ColdFusion root folder and your webroot. Every combination I try says either "LiveCycle Data Services is not installed at the specified location" or "Invalid root. The WEB-INF/flex folder must contain either flex-config.xml or services-config.xml." The flex-config.xml file is sitting in that directory. Is there some trick to getting this to work?

  • Actionscrips/Flex4: Display cut-off datapoints differently in LineChart

    - by Limited Atonement
    Dear Sirs, The issue arises when the user selects a range on the linechart that cuts off datapoints. When this happens, I would like the chart to tell the user somehow that there are data points three, just outside the range, perhaps by drawing a straight line across the top or bottom of the graph. How can I get Flex to do this for met? Let me know if you understand the question, or if you need more information, and of course, let me know the answer! Thanks! Sincerely, Aaron

  • Flex 4.5 - to long build process

    - by Idob
    We are developing an app using flex 4.5. The app runs just fine (no performance issues at all) but it takes us forever to compile and build it. A minor change, like just add a comment or press enter in an mxml file and rebuild takes about 3 minutes. You just cant work that way. It is a large project with about 1300 files. We also use Parsley as IOC container and a beat of cairngorm navigation. We also use Maven (Flex mojos) but I am talking about a normal eclipse build (Ctrl + B). We separated some of the code to a different SWC and all of our graphics are stored in a different resource SWF. Please, Do you have any suggestions? Regards, Ido

  • Seemingly simple skinning problem in Flex4; style gives disco effect

    - by Cheradenine
    I'm doing something wrong, but I can't figure out what. Simple project in flex4, whereby I create a skinned combobox (fragments at end). If I turn on the 3 skin references (over-skin, up-skin, down-skin), the combobox appears to simply stop working. If I remove the up-skin, hovering over the combo produces a flickering effect, where it appears to apply the style, then remove it immediately. I get the same thing with a button instead of a combo. I'm sure it's something really simple, but it's evading me. <?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" xmlns:containers="flexlib.containers.*"> <fx:Declarations> <!-- Place non-visual elements (e.g., services, value objects) here --> </fx:Declarations> <fx:Style> @namespace s "library://ns.adobe.com/flex/spark"; @namespace mx "library://ns.adobe.com/flex/mx"; #myCombo { over-skin: ClassReference("nmx.MyComboSkin"); up-skin: ClassReference("nmx.MyComboSkin"); down-skin: ClassReference("nmx.MyComboSkin"); } </fx:Style> <fx:Script> <![CDATA[ [Bindable] public var items:Array = ["A","B","C"]; ]]> </fx:Script> <mx:Canvas backgroundColor="#ff0000" width="726" height="165" x="20" y="41"> <mx:ComboBox id="myCombo" x="10" y="10" prompt="Hospital" dataProvider="{items}"> </mx:ComboBox> </mx:Canvas> </s:Application> Skin Definition: package nmx { import flash.display.GradientType; import flash.display.Graphics; import mx.skins.Border; import mx.skins.ProgrammaticSkin; import mx.skins.halo.ComboBoxArrowSkin; import mx.skins.halo.HaloColors; import mx.utils.ColorUtil; public class MyComboSkin extends ProgrammaticSkin { public function MyComboSkin() { super(); } override protected function updateDisplayList(w:Number, h:Number):void { trace(name); super.updateDisplayList(w, h); var arrowColor:int = 0xffffff; var g:Graphics = graphics; g.clear(); // Draw the border and fill. switch (name) { case "upSkin": case "editableUpSkin": { g.moveTo(0,0); g.lineStyle(1,arrowColor); g.lineTo(w-1,0); g.lineTo(w-1,h-1); g.lineTo(0,h-1); g.lineTo(0,0); } break; case "overSkin": case "editableOverSkin": case "downSkin": case "editableDownSkin": { // border /*drawRoundRect( 0, 0, w, h, cr, [ themeColor, themeColor ], 1); */ g.moveTo(0,0); g.lineStyle(1,arrowColor); g.lineTo(w-1,0); g.lineTo(w-1,h-1); g.lineTo(0,h-1); g.lineTo(0,0); // Draw the triangle. g.beginFill(arrowColor); g.moveTo(w - 11.5, h / 2 + 3); g.lineTo(w - 15, h / 2 - 2); g.lineTo(w - 8, h / 2 - 2); g.lineTo(w - 11.5, h / 2 + 3); g.endFill(); } break; case "disabledSkin": case "editableDisabledSkin": { break; } } } } }

I'm new to RoR, and I think I remember reading somewhere that every method should have a view. I'm just using this method to get info into the Flex 4 app, do I still need to make a view for it? Is that what's causing the error? Any help would be GREATLY appreciated, I've been stuck on this for a few days now! Thanks.

  • Given the presentation model pattern, is the view, presentation model, or model responsible for adding child views to an existing view at runtime?

    - by Ryan Taylor
    I am building a Flex 4 based application using the presentation model design pattern. This application will have several different components to it as shown in the image below. The MainView and DashboardView will always be visible and they each have corresponding presentation models and models as necessary. These views are easily created by declaring their MXML in the application root. <s:HGroup width="100%" height="100%"> <MainView width="75% height="100%"/> <DashboardView width="25%" height="100%"/> </s:HGroup> There will also be many WidgetViewN views that can be added to the DashboardView by the user at runtime through a simple drop down list. This will need to be accomplished via ActionScript. The drop down list should always show what WidgetViewN has already been added to the DashboardView. Therefore some state about which WidgetViewN's have been created needs to be stored. Since the list of available WidgetViewN and which ones are added to the DashboardView also need to be accessible from other components in the system I think this needs to be stored in a Model object. My understanding of the presentation model design pattern is that the view is very lean. It contains as close to zero logic as is practical. The view communicates/binds to the presentation model which contains all the necessary view logic. The presentation model is effectively an abstract representation of the view which supports low coupling and eases testability. The presentation model may have one or more models injected in in order to display the necessary information. The models themselves contain no view logic whatsoever. So I have a several questions around this design. Who should be responsible for creating the WidgetViewN components and adding these to the DashboardView? Is this the responsibility of the DashboardView, DashboardPresentationModel, DashboardModel or something else entirely? It seems like the DashboardPresentationModel would be responsible for creating/adding/removing any child views from it's display but how do you do this without passing in the DashboardView to the DashboardPresentationModel? The list of available and visible WidgetViewN components needs to be accessible to a few other components as well. Is it okay for a reference to a WidgetViewN to be stored/referenced in a model? Are there any good examples of the presentation model pattern online in Flex that also include creating child views at runtime?

  • How to user unloadStyleDeclarations?

    - by user300675
    I have a flex4 applciation (mx+spark). When I use: FlexGlobals.topLevelApplication.styleManager.loadStyleDeclarations(skinName, true); This works fine: new style is applied. The trouble is when I apply a new style, it mixes both: this happens because I need to Unload style first. I try to unload it with: FlexGlobals.topLevelApplication.styleManager.unloadStyleDeclarations("style/normal.swf",false); And I always got an error: ReferenceError: Error #1069: La property 0 cannot be found on Number and there is no default value. at normal/unloadOverrides()[null/normal-generated.as:721] at normal/unload()[null/normal-generated.as:676] Any idea on how to load/unload swf css in Flex4?

  • Trying to add a skinClass to <mx:Form>

    I'm working with Flex4 and I'm trying to skin a form (add a background and a border to it, etc.) I'm trying to do it the Flex 4 way with skinClass="" <mx:Form skinClass="skins.MyFormSkin" /> but it's not accepting skinClass as a property. How should I do it such that I'm still adhering to the best practices in Flex 4 (decoupling visuals from logic)?

  • Drawing Shapes in Flex 4/AS3 addchild issues

    - by Parris
    Hi All, I am simply trying to draw a rectangle inside of a panel using flex4. I am using spark instead of mx. It complains about addchild being replaced by addelement; however, addelement expects type ivisualcomponent. I think sprite should be of that type; however, it reports an error when trying to use the below code... I have tried a few different ways. I think I am missing something very basic about flex 4. Any enlightenment would be much appreciated! :-D private function drawRectangle(e:MouseEvent):void{ var s:Sprite = new Sprite(); s.graphics.beginFill(0x00ff00, 0.5); s.graphics.drawRect(e.localX,e.localY,50,50); s.graphics.endFill(); canvas.addChild(s); }

  • How can I define custom 'contentGroups' in a custom Flex 4 component?

    - by swidnikk
    The spark panel component for example can be written like this And its skin file will handle layout of the contentGroup, controlBarGroup, and titleDisplay. Notice, however that the contentGroup is doesn't appear in the code above and that the controlBarGroup accepts child mxml components. Now say I want to create a custom component that defines various required and non-required skinparts, such as 'headerGroup', 'navigationGroup', and 'accountPreferencesGroup'. I'd like to write this custom component like this The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to. Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?

  • Programatically enable/disable menuBar buttons in Flex 4

Currently the way that button clicks are detected is by a Switch/Case testing the String result of the MenuEvent [email protected] Maybe this isn't the best way?
