  • How do I programmatically trigger a mx:Button click event?

    - by knorv
    Consider the following mx:Button: <mx:Button click="doSomething()" id="myButton"/> Is there some way to programmatically emulate the user clicking the button? One obvious way to do it would simply be to call doSomething() which would give the same end result as clicking the button. But I'm specifically looking for ways to emulate the click -- that is something along the lines of myButton.click() (if that should have existed).

  • AS3IsoLib New IsoSprite

    - by KoopaTroopa
    I'm following a guide (http://www.jsparrowhawk.com/blog/?p=75) on how to use the As3IsoLib library. It seems his examples are a little erroneous at times. I'm at the part of creating a sprite, assigning it an image and then rendering. When I test my application I get my box and grid but not the sprite. var mySprite:IsoSprite; mySprite = new IsoSprite(); mySprite.setSize(40, 40, 0); mySprite.moveTo(120, 40, 0); scene.addChild(mySprite); var myImgLoader:Loader = new Loader(); var myImgURL:URLRequest = new URLRequest("http://www.jsparrowhawk.com/blog/wp-content/uploads/2011/10/as3isolib_styling_6b.jpg"); myImgLoader.load(myImgURL); myImgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imgLoadComplete); function imgLoadComplete(e:Event):void { var myImg:Bitmap = new Bitmap(e.target.content.bitmapData); mySprite.sprites = [myImg]; scene.render(); }

  • 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.

  • 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!

  • Single Loader to multiple Sprite Possible?

    - by Jeffrey Chee
    I've looked in various resources regarding this topic, and it seems to me that I need a Loader for every Sprite which contains an image file (png). I'm trying to make a Tile Rendering System, and have created a grid of X by Y sprites, but all of them actually reference the same image file. Is there any other way to do this? (Make the sprite share the same png data file) Some sample code of what I have done. // Create an array of X * Y Loaders var cTileLoaders:Array = new Array( 100 ); // for example 10 by 10 grid var cTiles:Array = new Array( 100 ); var nIndex:int = 0; var nImgLoadCount:int = 0; for ( ; 100 > nIndex; ++nIndex ) { cTileLoaders[ nIndex ] = new Loader(); cTiles[ nIndex ] = new Sprite(); // perform more sprite initialization .... cTileLoaders[ nIndex ].contentLoaderInfo.addEventListener( Event.COMPLETE, ImageLoaded cTileLoaders[ nIndex ].Load( new URLRequest( "some image path" ) ); } // handler for image loaded function ImageLoaded( eEvent:Event ):void { ++nImgLoadCount; // when all 100 sprite data are loaded // assuming there is no i/o error if ( 100 == nImgLoadCount ) { cTiles[ nIndex ].addChild( cTileLoaders[ nIndex ].content ); } }

  • 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?

  • [FLEX] Images won't dynamically refresh

    - by Bridget
    I am writing a Flex application to receive xml from an httpservice. That works because I can populate a datagrid with the information. The xml sends image pathnames. A combobox sends a new HttpService call onChange. This repopulates the datagrid and puts new images in the folder that flex is accessing. I want to dynamically change the image without changing the pathname of the image. <mx:Canvas id="borderCanvas"><mx:Canvas id="dropCanvas"> <mx:Tile id="adTile"><mx:Image></mx:Image> </mx:Tile></mx:Canvas></mx:Canvas> This is my component. I assign my Image sources using this code: var i:Number = 0; while ( i <= dg_conads.rowCount){ var img:Image = new Image(); img.source = null; img.source = imageSource+i+".jpg"; adTile.addChild(img); i++; } My biggest problem is that the images are not refreshing. I get the same image even though I've prevented caching from the HTML wrapper and the ASP.Net website. The image automatically loads in the folder and refreshes in the folder but I can't get the image to refresh in the application. I've tried removeAllChildren(); delete(adTile.getChildAt(0)); and neither worked.

  • What is the proper method to stop loading a Flex Module before it has completely loaded?

    - by Michael Prescott
    I seem to recall that Loader.unload() could once be used to stop loading a swf before it had finished loading. I can no longer find documentation or the blog where I read this. Perhaps it was an unofficial feature. Anyhow, IModuleInfo, returned by ModuleManager.getModule() has an unload() method. If I want to halt loading a Flex Module that is in progress, do I just call iModuleInfo_instance.unload()?

  • How to automatically include a number of images in the SWF file?

    - by Ponty
    Hi, i'm trying to include a number of images in my SWF file not by loading them but by embedding them in the SWF itself. I found the following instruction to do that: [Embed(source="../graphics/images/ss0.png")] private var SS0:Class; Basically, i want to embed a different number of images each time. Is there a way to do that automatically (let's say inside a for loop) or do i have to type manually this instruction for each image i want to include?

  • 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?

  • What encoding uses Flash Builder to send non english data to server?

    - by Ole Jak
    In my site I use Unicode... I hoped when I'll connect Flash Builder to my server (using Data - connect to HTTP ) It will work with my API sending Russian text as UTF-8 but instead it sends Þûõó ïúушúøý to my API and so to DB and so on instead of my favourite UTF-8 &#1056;&#1091;&#1089;&#1089;&#1082;&#1086;&#1077; &#1048;&#1084;&#1103; 2... So what encoding uses flash builder and How to make Flash Application send UTF-8 data to my server or some other readable format?

  • How do I dynamically create Flex 4 AddChild actions for States?

    - by TK Kocheran
    I have an application in which I need to create mx.states.State objects on the fly, as I'm reading external data in order to create the states. Each State only has a single child, so here's my code which I was using to accomplish this: var state:State = new State(); state.name = "a"; state.overrides = [new AddChild(parent, DisplayObject(view))]; this.states.push(state); However, when I actually change a state, I get a runtime error relating to the fact that you can't call addChild on a spark.components.Group component. Is there an equivalent AddElement action for adding elements to a Group during a state change?

  • Keeping the number of objects and event-listeners on stage as low as possible

    - by DevEight
    Hello. I am creating a site with lots of big scrollable text-boxes in it. Each text-box object contained some text, and two buttons to scroll up/down with. The scroll buttons each had an event listener so the text moved when you clicked them. These text-boxes were stacked on-top of each other with all except one having an alpha of 0. If I wanted to change which text-box is active I move it to the front and call a small TweenLite animation. To the left (outside of the text-box objects) I have an object similar to a menu. It also has about 12 or so event-listeners (one for every button). This turns out cause A LOT of lag an it's very troublesome for my laptop to run it. What I need help with doing is to reduce the number of event-listeners on the stage and also the amount of text-boxes. What I was thinking was to add the text-boxes using AS so I only have 1 on the stage at a time but I couldn't figure out how to do it. I also thought it might be better to just use 1 big event-listeners and from mouseX and mouseY decide which button the user is trying to push. Are there any better alternatives to this? And if so, please elaborate on how to do it.
