  • AS3 URLRequest in for Loop problem

    - by Adrian
    Hi guys, I read some data from a xml file, everything works great besides urls. I can't figure what's the problem with the "navigateURL" function or with the eventListener... on which square I click it opens the last url from the xml file for(var i:Number = 0; i <= gamesInput.game.length() -1; i++) { var square:square_mc = new square_mc(); //xml values var tGame_name:String = gamesInput.game.name.text()[i];//game name var tGame_id:Number = gamesInput.children()[i].attributes()[2].toXMLString();//game id var tGame_thumbnail:String = thumbPath + gamesInput.game.thumbnail.text()[i];//thumb path var tGame_url:String = gamesInput.game.url.text()[i];//game url addChild(square); square.tgname_txt.text = tGame_name; square.tgurl_txt.text = tGame_url; //load & attach game thumb var getThumb:URLRequest = new URLRequest(tGame_thumbnail); var loadThumb:Loader = new Loader(); loadThumb.load(getThumb); square.addChild(loadThumb); // square.y = squareY; square.x = squareX; squareX += square.width + 10; square.buttonMode = true; this.addEventListener(MouseEvent.CLICK, navigateURL); } function navigateURL(event:MouseEvent):void { var url:URLRequest = new URLRequest(tGame_url); navigateToURL(url, "_blank"); trace(tGame_url); } Many thanks!

  • Javascript API not working for Chrome or Safari on JW Player 5.9

    I am working on a custom interface for the JW Player which displays the current track title and has play/pause, next track, previous track and volume toggle buttons.

  • How do I get textbox to fill the column and autoscroll?

    - by Stephen Price
    I have the following code in my DataGridTemplateColumn: <Controls:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBox Text="{Binding AlternateTeacherName, Mode=TwoWay}" Style="{StaticResource InputTextBox}"/> </StackPanel> </DataTemplate> Style is: <Style x:Key="InputTextBox" TargetType="TextBox" > <Setter Property="Margin" Value="1" /> <Setter Property="MinWidth" Value="30" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Background" Value="Transparent" /> <Setter Property="VerticalAlignment" Value="Center" /> <Setter Property="TextAlignment" Value="Left" /> <Setter Property="HorizontalAlignment" Value="Stretch" /> Problem I'm getting is that the textbox fills the column width correctly (including when you resize it) but if I type into the textbox the cursor is not visible when it reaches the end of the line. I'd like the text to scroll off the left so that the current text is still visible. thanks

  • RichFaces a4j:support parameter passing

    - by Mark Lewis
    Hello I have a number of rich:inplaceInput tags in RichFaces which represent numbers in an array. The validator allows integers only. When a user clicks in an input and changes a value, how can I get the bean to sort the array given the new number and reRender the list of rich:inplaceInput tags so that they're in numerical order? EG <a4j:region> <rich:dataTable value="#{MyBacking.config}" var="feed" cellpadding="0" cellspacing="0" width="100%" border="0" columns="5" id="Admin"> ... <a4j:repeat... <a4j:region id="MsgCon"> <rich:inplaceInput value="#{h.id}" validator="#{MyBacking.validateID}" id="andID" showControls="true"> <a4j:support event="onviewactivated" action="#{MyBacking.sort}" reRender="Admin" /> </rich:inplaceInput> </a4j:region> </a4j:repeat> </data:Table> </a4j:region> Note I do NOT want to use dataTable sort functions. The table is complicated and I've specified id="Admin" (ie the whole table) to reRender as I've not found a way to send more localised values to the backing bean through the inplaceInput. This question is about how to use a4j:support action attribute to call the sort method so that when the reRender rerenders the component, it outputs the list in sorted order. I have the sort method working ok when I click a button to sort, but I want to have the list sorted automatically as soon as a new valid value is entered into the inplaceInput component. Thanks

  • Is there a fast alternative to creating a Texture2D from a Bitmap object in XNA?

    - by Matthew Bowen
    I've looked around a lot and the only methods I've found for creating a Texture2D from a Bitmap are: using (MemoryStream s = new MemoryStream()) { bmp.Save(s, System.Drawing.Imaging.ImageFormat.Png); s.Seek(0, SeekOrigin.Begin); Texture2D tx = Texture2D.FromFile(device, s); } and Texture2D tx = new Texture2D(device, bmp.Width, bmp.Height, 0, TextureUsage.None, SurfaceFormat.Color); tx.SetData<byte>(rgbValues, 0, rgbValues.Length, SetDataOptions.NoOverwrite); Where rgbValues is a byte array containing the bitmap's pixel data in 32-bit ARGB format. My question is, are there any faster approaches that I can try? I am writing a map editor which has to read in custom-format images (map tiles) and convert them into Texture2D textures to display. The previous version of the editor, which was a C++ implementation, converted the images first into bitmaps and then into textures to be drawn using DirectX. I have attempted the same approach here, however both of the above approaches are significantly too slow. To load into memory all of the textures required for a map takes for the first approach ~250 seconds and for the second approach ~110 seconds on a reasonable spec computer. If there is a method to edit the data of a texture directly (such as with the Bitmap class's LockBits method) then I would be able to convert the custom-format images straight into a Texture2D and hopefully save processing time. Any help would be very much appreciated. Thanks

  • CSS: Making two transparent images overlapping

    - by Pierre
    Hi all, I'm trying to make two transparent images (having the same size/dimension ) overlapping into a div at their top left corner. I tried: <html xmlns="http://www.w3.org/1999/xhtml"> <body> <div style="margin:20px;"> <div id="main" style="overflow:hidden;background-color:red;width:400px;height:400px;border:3px solid blue;"> <img src="myimage1.png" style="position:relative;top:0px;left:0px;z-index:0;"/> <img src="myimage2.png" style="position:relative;top:0px;left:0px;z-index:10;"/> </div> </div> </body> </html> but it doesn't work, the two pictures are concatenated into the parent div.

    Hi. I want to know how to correctly write an if statement with jquery. I have a bunch of div's with an anchor in each that when clicked expands the the div's width using toggleClass.

  • QuadTrees - how to update when internal items are moving

    - by egarcia
    I've implemented a working QuadTree. It subdivides 2-d space in order to accomodate items, identified by their bounding box (x,y,width,height) on the smallest possible quad (up to a minimum area). My code is based on this implementation (mine is in Lua instead of C#) : http://www.codeproject.com/KB/recipes/QuadTree.aspx I've been able to successfully implement insertions and deletions successfully. I've turn now my attention to the update() function, since my items' position and dimensions change over time. My first implementation works, but it is quite naïve: function QuadTree:update(item) self:remove(item) return self.root:insert(item) end Yup, I basically remove and reinsert every item every time they move. This works, but I'd like to optimize it a bit more; after all, most of the time, moving items still remain on the same quadTree node most of the iterations. Is there any standard way to deal with this kind of update? In case it helps, my code is here: http://github.com/kikito/passion/blob/master/ai/QuadTree.lua I'm not looking for someone to implement it for me; pointers to an existing working implementation (even in other languages) would suffice.

  • HTML checkbox field is being passed to PHP as checked even when it is not

    - by Ryan
    Hello all, First of all thanks in advance, this has been very frustrating and I'm hoping someone can see something I'm not, I am definitely no php expert. Well here' what is going on. I have a form where I have a checkbox for people to opt in to our newletter. The form element looks like this: <label for=newsletter accesskey=N class="checkbox">Signup for Cloverton's Newsletter</label> <input name="newsletter" type="checkbox" id="newsletter" value="Yes" style="width:20px;" /> That is then submitted to a php file with this code: if (isset($_POST['newsletter']) && $_POST['newsletter'] == 'Yes'){ echo "newletter yes"; $newsletter = 1; }else{ echo "newsletter no"; $newsletter = 0; } $newsletter is then inserted into a database field. The issue is that whether the box is checked or not it is being sent to php as true, so every entry is receiving the newsletter. Any help would be greatly appreciated! Thanks!

  • generating images with php based on css3 gradient settings?

    - by thrice801
    Hi, Does anyone know if there is a php library, or if there isnt, have any input on how one would go about generating an image via php, from basic HTML element input settings, and CSS 3 gradient parameters. To give an example on why this would be useful, I have found as of a couple days ago, that laying out the wireframe for a webpage using basic Css3 gradient styling speeds up my design and development time by, well, alot. I cant design from photoshop, Ill spend hours tweaking stupid little things that only lead to me tweaking more stupid little things to compensate for stupid little changes. -- So, I had an epiphany to stop using photoshop until the end, and just focus on the main styling of elements, text-shadow, and borders for highlights, and I feel I am able to make super clean, more focused layout by being more restricted to the basics of graphic design with just css. Anyways, so Im planning on after I have the layouts done, to then recreate the graphics in photoshop, so that every browser is able to render the images. This wont take long, but as far as repeating it goes, if I could just do it with PHP, that would be incredible. For instance, take this style for example, which renders a clean looking ipad/pod ish menu/button gradient. [code] background: -moz-linear-gradient(top, #808080, #454545 50%, #313131 51%, #333333); background: -webkit-gradient(linear, left top, left bottom, color-stop(0, #808080), color-stop(.5, #454545), color-stop(.5, #313131), to(#333333));[/code] Basically what Im looking to do is take one or more inputs that control rendering the image as you see there. Take a width and a height input, and then render the image gradient accordingly, so I can save it, upload it and then use it in my designs. So ya, I know PHP has some image generation capabilities but I dont know to what extent, any input on the most effective way to go about doing this or whether it already exists, would be appreciated!

  • How do I reliably get the size of my iPhone view taking rotations into consideration?

    - by Sebastian Celis
    My application uses a UITabBarController, multiple UINavigationControllers, and supports autorotation. In order to properly layout the subviews within each UIViewController's main view, I really need to know the size available to the UIViewContoller. I need this size to take the UINavigationBar, the UITabBar, and the status bar all into account, and thus only return the size available to the content view. I thought for sure I could use the following from within the UIViewController's code: CGRect viewControllerBounds = [[self view] bounds]; However, there are a couple of issues with this approach: The first time the view is loaded, viewControllerBounds reports the view as being 320 pixels wide by 460 pixels tall. This is wrong. With a status bar and a navigation bar showing, the height should only be 416 pixels. However, if I rotate the simulator to landscape and then rotate back, the height of viewControllerBounds changes to 416. If I rotate the first view in the navigation controller to landscape mode and then push another view controller onto the stack, viewControllerBounds for the new view reports a width of 300 pixels and a height of 480 pixels. So the view's bounds didn't even take the rotation into account. Is there a better way to do this? I really don't want to have to start hardcoding the widths and heights of all the various UI elements the iPhone OS provides. I have tried setting the autoresizing mask of the UIViewController's view, but that doesn't seem to change anything. The views definitely seem to be displaying properly. When I set a background color that view looks like it takes up all of the space available to it. Any pointers would be greatly appreciated.

  • Scaling Image to multiple sizes for Deep Zoom

    - by AnthonyWJones
    Lets assume I have a bitmap with a square aspect and width of 2048 pixels. In order to create a set of files need by Silverlight's DeepZoomImageTileSource I need to scale this bitmap to 1024 then to 512 then to 256 etc down to 1 pixel image. There are two, I suspect naive, approaches:- For each image required scale the original full size image to the required size. However it seems excessive to be scaling the full image to the very small sizes. Having scaled from one level to the next discard the original image and scale each sucessive scaled image as the source of the next smaller image. However I suspect that this would generate images in the 256-64 range with poor fidelity than using option 1. Note unlike with the Deep Zoom Composer this tool is expected to act in an on-demand fashion hence it needs to complete in a reasonable timeframe (tops 30 seconds). On the pluse side I'm only creating a single multiscale image not a pyramid of mutliple high-res images. I am outside my comfort zone here, any graphics experts got any advice? Am I wrong about point 2? Is point 1 reasonably performant and I'm worrying about nothing? Option 3?

  • initialising a 2-dim Array in Scala

    - by Stefan W.
    (Scala 2.7.7:) I don't get used to 2d-Arrays. Arrays are mutable, but how do I specify a 2d-Array which is - let's say of size 3x4. The dimension (2D) is fixed, but the size per dimension shall be initializable. I tried this: class Field (val rows: Int, val cols: Int, sc: java.util.Scanner) { var field = new Array [Char](rows)(cols) for (r <- (1 to rows)) { val line = sc.nextLine () val spl = line.split (" ") field (r) = spl.map (_.charAt (0)) } def put (val rows: Int, val cols: Int, c: Char) = todo () } I get this error: :11: error: value update is not a member of Char field (r) = spl.map (_.charAt (0)) If it would be Java, it would be much more code, but I would know how to do it, so I show what I mean: public class Field { private char[][] field; public Field (int rows, int cols, java.util.Scanner sc) { field = new char [rows][cols]; for (int r = 0; r < rows; ++r) { String line = sc.nextLine (); String[] spl = line.split (" "); for (int c = 0; c < cols; ++c) field [r][c] = spl[c].charAt (0); } } public static void main (String args[]) { new Field (3, 4, new java.util.Scanner ("fraese.fld")); } } and fraese.fld would look, for example, like that: M M M M . M I get some steps wide with val field = new Array Array [Char] but how would I then implement 'put'? Or is there a better way to implement the 2D-Array. Yes, I could use a one-dim-Array, and work with put (y, x, c) = field (y * width + x) = c but I would prefer a notation which looks more 2d-ish.

  • jQuery.post() issues with passing data to jQuery UI

    - by solefald
    Hello, I am trying to get jQuery.post() to run my php script and then open a jQuery UI dialog with the data that php script returns. Its supposed to come back as a form with a table and a textarea in it. It works great with alert(data); and i get a pop-up with all my data. The problem starts if i turn off alert(). Now it opens 2 dialogs. One containing only the table, without textarea, and the second one absolutely empty. What am i doing wrong here? How come all my data shows up in the alert(), but not in dialog? What do i need to do to fix it? Oh, and do i need to also include $.ajax() before the $.post()? Thank you. $.post("/path/to/script.php", { id: this.id, value: value }, function(data){ // THIS WORKS //alert(data); // THIS DOES NOT WORK $(data).dialog({ autoOpen: true, width: 400, modal: true, position: 'center', resizable: false, draggable: true, title: 'Pending Changes' }); } );

  • "Link" against a SWC in Flex

    - by ggambett
    I'm trying to do a very simple app in Flash/Flex, that loads an image embedded in the swf itself and then shows it. The thing is I'm trying to do it using the command line only (mxmlc and compc) and without using @Embed, and failing miserably. I have a very simple Main.as : package { import flash.display.*; import flash.utils.*; public class Main extends Sprite { public function Main () : void { var pDef:Class = getDefinitionByName("icon_big.png") as Class; var _image:BitmapData = new pDef(0, 0); var pSprite:Sprite = new Sprite(); pSprite.graphics.beginBitmapFill(_image); pSprite.graphics.drawRect(0, 0, _image.width, _image.height); pSprite.graphics.endFill(); addChild(pSprite); } } } This works fine if I add icon_big.png to the Library using the Flash IDE, but I can't figure out how to do it from the command line. I'm using compc to put the png inside a swc : compc --include-file icon_big.png icon_big.png -output assets.swc This generates a 17 kb assets.swf, slightly bigger than icon_big.png. Then I try to compile and link Main.as : mxmlc -include-libraries+=assets.swc Main.as This produces a 944 byte Main.swf, which clearly doesn't include the asset, and fails at runtime. According to the mxmlc docs I found, -include-libraries should link with every class, including the ones not directly referenced by code (as is the case here, since I'm getting the class from code), and it unsurprisingly fails at runtime. Note that this same code (or, more precisely, quite equivalent code) works when used within a Flash project - I'm not looking to fix the code, but how to do in the command line whatever Flash does internally. I feel I'm just "not getting" something... any clues?

  • In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track

    - by Tony
    I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") }); FB.ensureInit(function () { FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback); }); However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error - FB.ApiClient is undefined I am also using the FBML fan tag to display the "become a fan" button: <fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan> And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan. The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.

  • Making alpha PNGs with PHP GD

    - by WiseDonkey
    Hello, I've got a problem making alpha PNGs with PHP GD. I don't have imageMagik etc. Though the images load perfectly well in-browser and in GFX programs, I'm getting problems with Flash AS3 (actionscript) understanding the files. It complains of being an unknown type. But, exporting these files from Fireworks to the same spec works fine. So I'm suggesting it's something wrong with the formatting in PHP GD. There seems to be a number of ways of doing this, with several similar functions; so maybe this isn't right? $image_p = imagecreatetruecolor($width_orig, $height_orig); $image = imagecreatefrompng($filename); imagealphablending($image_p, false); ImageSaveAlpha($image_p, true); ImageFill($image_p, 0, 0, IMG_COLOR_TRANSPARENT); imagealphablending($image_p, true); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width_orig, $height_orig, $width_orig, $height_orig); imagepng($image_p, "new2/".$filename, 0); imagedestroy($image_p); This just takes files it's given and puts them into new files with a specified width/height - for this example it's same as original but in production it resizes, which is why I'm resampling.

  • Why setPreferredSize does not change the size of the button?

    - by Roman
    Here is the code: import javax.swing.*; import java.awt.event.*; import java.awt.*; public class TestGrid { public static void main(String[] args) { JFrame frame = new JFrame("Colored Trails"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); JPanel panel = new JPanel(); panel.setLayout(new GridLayout(4, 9)); panel.setMaximumSize(new Dimension(9*30-20,4*30)); JButton btn; for (int i=1; i<=4; i++) { for (int j=1; j<=4; j++) { btn = new JButton(); btn.setPreferredSize(new Dimension(30, 30)); panel.add(btn); } btn = new JButton(); btn.setPreferredSize(new Dimension(30, 10)); panel.add(btn); for (int j=1; j<=4; j++) { btn = new JButton(); btn.setPreferredSize(new Dimension(30, 30)); panel.add(btn); } } mainPanel.add(panel); frame.add(mainPanel); frame.setSize(450,950); frame.setVisible(true); } } I suppose to have a table of buttons with 4 rows and 9 columns. And the middle column should be narrower that other columns. I tried Dimension(30, 10) and Dimension(30, 10) both have no effect on the width of the middle column. Why?
