  • CheckBox header renderer with HierarchicalCollectionView

    - by fumeng
    Hi - I've gotten a checkbox header renderer to work well with flat DPs, but a hierarchical collection view is another story. On click, I want it to select all checkboxes in a given column. Here is my code: var dp:HierarchicalCollectionView = _dataGrid.dataProvider as HierarchicalCollectionView; var testDp:GroupingCollection = dp.source as GroupingCollection; var rawDp:ArrayCollection = testDp.source as ArrayCollection; for(var i:int=0 ; i < rawDp.length ; i++){ rawDp[i][_dataField] = cb.selected; } It selects all checkboxes on the 2nd level of data, but doesn't select the top level of data. What am I missing here? I can't seem to find it. Any tips are greatly appreciated. Thank you.

  • Is html/javascript equivalent to as3/flex?

    - by DJ.
    Hello my fellow coders, As i notice for a while now (like everybody else in the industry), the RIA market is shifting from AS3/Flex to HTML/Javascript. What i would like to know is? Is html/javascript as powerfull as as3/Flex or are they entirely different. With other words can i build the exact same applictions with HTML(4/5) and Javascript as i can do with AS3/Flex? I'm not looking for the speed comparison? or bashing one technology over the other? I just want to know if is good for me to dive into javascript, JQuery...... PS. If there is a nother post on stackoverflow with the exacte question. please share the link. Thanks. Thank you.

  • Create and define Vector

    - by zdmytriv
    I'm looking for method to create Vector and push some values without defining variable Vector. For example: I have function: public function bla(data:Vector.<Object>):void { ... } this function expects Vector as parameter. I can pass parameters this way var newVector:Vector.<Object> = new Vector.<Object>(); newVector.push("bla1"); newVector.push("bla2"); bla(newVector); Can I do it in one line in Flex? I'm looking for something like: bla(new Vector.<Object>().push("bla1").push("bla2")); I've also tried this: bla(function():Vector.<Object> { var result:Vector.<Object> = new Vector.<Object>(2, true); result.push("bla1"); result.push("bla2"); return result; }); But it complains: 1067: Implicit coercion of a value of type Function to an unrelated type __AS3__.vec:Vector.<Object>... Thanks

    - by redn0x
    I have a table with a Screen on it underneath there are 2 mouses I need to determin the position of the table. This will manipulate the content on the screen. I already can get the mouse input using the multipoint SDK from microsoft, I only keep failing at the mathemathics. My question now is, how would you determine the position of the table using 2 mouses?

  • How do I refer to an instance from inside it's own code in Adobe Flash.

    - by matt1024
    In Adobe Flash, I have a movie clip that is added to the stage when the keyboard is pressed. I want it to travel across the screen and disappear once it reaches the edge of the stage. At the moment I use this but the image appears and then stops. Here is my code: addEventListener(Event.ADDED_TO_STAGE,runtime); var c = 0 function runtime(){ while(this.x<800){ this.x += 12; } removeChild(this); } Thanks

  • How do I change the application background color at run-time in a Flex 3.5 application?

    - by Adam Tuttle
    I have a Flex 3.5 application that will serve multiple purposes, and as part of the visual changes that I'd like to make to indicate which mode the application is in, I want to change its background color. Currently, the application tag looks like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:com="ventures.view.component.*" xmlns:views="ventures.view.*" layout="absolute" preinitialize="onPreInitialize()" creationComplete="onCreationComplete()" applicationComplete="onApplicationComplete()" click="onClick(event)" enabled="{(!chainController.generalLocked)}" backgroundGradientColors="[0xFFFFFF, 0xFFFFFF]" > I've tried using a binding, for both the backgroundColor and backgroundGradientColors attributes: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundColor="{app_background_color}" > —and— <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundGradientColors="{app_background_color}" > but for the former binding is not allowed, and for the latter there is a warning that: Data binding will not be able to detect assignments to "app_background_color". I also ran across this page which seems to indicate that I could do it with the setStyle() method, but the documentation seems to indicate that this method is only available for components, not the main canvas. I suppose I could wrap everything in a <mx:Canvas></mx:Canvas> specificially for this purpose, but that seems wasteful—like Div-itis in HTML or something. What's the best way to change the main application background color at run-time?

  • How would you update 100+ variables if something is changed in a different class?

    - by N. Lucas
    I have a class Grid which produces a graph paper like grid on in the drawing area. I then have 5 other classes for different shapes to draw with; Line, Polygon, Ellipse, Curve, Arc Now, these 5 classes use an instance of Grid because Grid has a resolution and a scale. Inside Grid I have: public function set resolution(x:Number):void { _gap = (modBy10(x) / 10); _scale = (modBy10(x) / (this.resolution * _scale)); draw(); } public function get resolution():Number { return (_gap * 10); } public function set scale(x:Number):void { _scale = (this.resolution / x); } public function get scale():Number { return _scale; } /**/ public function scaleLength(x:Number):Number { return (x * this.scale); } public function scaleLengthDown(x:Number):Number { return (x / this.scale); } public function scaleArea(x:Number):Number { return (x / Math.pow(this.scale, 2)); } I'm just lost for a solution on how to update every instance of my 5 drawing classes when Grid is changed. For instance, Polygon is made up of multiple instances of Line, Line(length, angle) where "length" is in either in, ft, cm, or m. If the user wishes to change the scale from say 10ft per 100px resolution.. Is there an easier way than re-drawing every Line inside Polygon?

  • trouble with custom 'Text Bubble' component (examples included)

    - by gmoniey
    I'm trying to use a custom Text component to show a series of comments. I got the original idea from: http://www.eonflex.com/?p=40 I've got the base case working but I am stuck with 2 problems I cant seem to figure out: Since I am drawing around the text, the actual height of each bubble is greater than that of the Text field, as a result, the last bubble is always chopped off. I have tried explicitly overriding the height getter, and adding some padding, but I cant seem to get it right. You can see an example here: http://test.lambandtunafish.com/bubbles/CommentTest.swf In my layout, I have 2 VBoxes (one nested inside the other). The first vbox shows a form where the user can enter a comment, and the second box has all the comments. In order to ensure that the scrollbars only show up on the second box, I set minHeight="0" on the nested VBox, but then for some reason, some comments' text is shifted to the right. You can see an example here (look at the first comment): http://test.lambandtunafish.com/bubbles/CommentTest-minHeight.swf Rather than posting the code here, I've provided some links: Container: http://test.lambandtunafish.com/bubbles/CommentTest.mxml Bubble: http://test.lambandtunafish.com/bubbles/CommentBubble.as If anyone has any ideas, I would appreciate it. Thanks!

  • My code gets an argument error, expecting 1 but got 0 - AS3

    - by Louis Cottier
    I've got this code with a variable of platform, which I'm trying to link with the actual object of Platform in my .fla file but I get this error when I run it; ArgumentError: Error #1063: Argument count mismatch on Code(). Expected 1, got 0. In my output window. package { import flash.display.MovieClip; import flash.events.MouseEvent; import flash.events.KeyboardEvent; import flash.events.Event; import flash.ui.Keyboard; public class Code extends MovieClip { var charSpeed:int = 0; var velocity:int = 0; var gravity:Number = 1; var Jump:Boolean = false; public function startGame(){ stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeyDown); stage.addEventListener(KeyboardEvent.KEY_UP, checkKeyUp); stage.addEventListener(Event.ENTER_FRAME, loop); } private var platform:Platform; public function Code(value:Platform) { platform = value; } function checkKeyDown(evt:KeyboardEvent){ if (evt.keyCode == Keyboard.LEFT){ charSpeed -= 10; } if (evt.keyCode == Keyboard.RIGHT){ charSpeed += 10; } if (evt.keyCode == Keyboard.DOWN){ if(!Jump){ velocity -= 14; Jump = true; } } } function checkKeyUp(evt:KeyboardEvent){ if (evt.keyCode == Keyboard.LEFT){ charSpeed = 0; } if (evt.keyCode == Keyboard.RIGHT){ charSpeed = 0; } } function loop(evt:Event){ player.x = velocity; if (player.x < 0){ player.x = 0; } if (player.x > 550){ player.x = 550; } velocity += gravity; var Platform:Array = new Array(platform) if (!Platform.hitTestPoint(player.x, player.y, true)){ player.y += velocity; } for (var i = 0; i < 10; i++){ if (Platform.hitTestPoint(player.x, player.y, true)){ player.y--; velocity = 0; Jump = false; } } } } } The as3 file name is Code, and the fla file name is Game. My objective is to get my player to move around on the platform using the arrow keys. The linkage of my platform is "Platform". If anyone could help that would be great

  • Flash AS3 - Access external swf on the same domain

    - by christinelalala
    Hi, I ran into this problem and could not solve it, so I have a swf file that loads assets from another swf file, everything's fine, until I put them on the server, they are under the same domain, relative path doesnt work nor does absolute path. This is not even a cross domain problem, since both files are on the same server. Did anyone ever have the same problem? Thanks.

  • Can I use a string variable to reference a class variable?

    - by rson
    Here's the scenario: I have an external swf file with x number of movieclips in its library that I load into a containing swf. Each MC in the external swf is linked with a class name and referenced on frame 1 as such var unique1:lineSequence1 = new lineSequence1(); the unique1 variable name will match a string variable I create in the containing swf: function initLines():void{ lineLoader = new Loader(); lineLoader.load(new URLRequest("theLines.swf")); //load external swf lineLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, linesLoaded); } function linesLoaded(e:Event):void{ var loadedswf:MovieClip = e.target.content as MovieClip; var initialLines = projects[0].pageid; //projects is an xmllist trace("initialLines: "+initialLines); //returns "initialLines: unique1" lines_holder_mc.addChild(loadedswf.[initialLines]); } I would like to use the initialLines variable as the reference to unique1 instead of hardcoding unique1 into loadedswf.unique1 to reference said variable in the loaded swf.

  • AIR app still running when the iphone is blocked?

    - by nmarti
    I just made a simple game with flash professional 6.0 and adobe AIR sdk 3.4 for iPhone. The problem is this: when I lock the iphone pressing the power button, the screen switches off as usual, but the music of the game still sounds. If I exit the game pressing the home button it exits fine. Is only when locking the phone with the app opened. Also, I opted-out of multitasking for my app, so if I close my app with the home button and I reload it, it loads the main menu. Anyone knows how can I solve this?

  • using html text in as3

    - by vincent
    Hello, i'm having a bit of a question, I have some newspost from my database. But there are tags in it and some tags aswell. My questiion is how i should go about it to get the newspost showing as it should be. The images should get shown instead of the tags etc. I know i'll have to work with a loader to use the images but how would as3 recognize them? Is there anyway i could use htmltext or something so as3 knows automaticly where the imagetags are? Also, if i add the image would it be possible to wrap the text around it? So i dont have an empty space next to the image?

  • How do I retrieve twitter xml for Flash site via php properly

    - by daidai
    Am I using TwitterScript to retrieve Twitter data for inside a Flash site. Due to Twitter's crossdomain policy, I need to setup a php proxy... Firstly I made a simple one <?php $url = $_GET['url']; readfile($url); ?> but I then get this error URL file-access is disabled in the server configuration which is only resolved by getting my host to turn fopen() on, which I don't want to do. Then I found this <?php function get_content($url) { $ch = curl_init(); curl_setopt ($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_HEADER, 0); ob_start(); curl_exec ($ch); curl_close ($ch); $string = ob_get_contents(); ob_end_clean(); return $string; } #usage: $url = $_GET['url']; $content = get_content ($url); var_dump ($content); ?> which solves that problem but the data now is the correct XML but looks like: string(39950) "<?xml version="1.0" encoding="UTF-8"?> <statuses type="array"> <status> ... </statuses>" How do I get the XML data out of that string?

  • [Flex] Using same set of columns in AdvancedDataGrid in a TabBar

    - by user283403
    I have a TabBar control which will show an AdvancedDataGrid with same set of columns on different tabs, i am doing this so that i can show similar data on different tab pages. Column heading will be the same on all grids, is there a way I can put all column headings in an array and set that as columns of data grid? I tried setting the columns property but it doesn't work. Also I need to set ID property for a single column in the grid to set it the treecolumn so one column must have individual id field too.

  • MovieClip changes Stage alignment

    - by Nicholas Cowle
    I am loading a MovieClip using MovieClipLoader. When the MovieClip starts playing, it changes the alignment of my stage to LT, which incorrectly repositions all the other objects on my stage. Is there anyway for me to: Prevent the MovieClip from changing the alignment of my stage? Adding an event handler to an appropriate event, so that I can reset the stage alignment when it gets changed? I have already tried resetting the stage alignment on the onLoadInit event of MovieClipLoader and the onEnterFrame event of MovieClip, but both seem to reset the alignment too soon.

  • Displaying data points in Flex Line chart...

    I have a flex line chart. Instead of the default behavior of having to hover over parts of the line to see the data points, is there a way to change the rendering of each point and have them always displayed? (almost like a connect the dots type view).
