  • Mouse move panning

    - by Rudy
    Hi all, I'm trying to scroll a series of thumbnails horizontally based on the mouseX position. I can get it to scroll but it's very choppy and for some reason it's not reading my start and end numbers so it will stop scrolling. Can anyone point me in the right direction? Thanks. var thumbBounds:Object = new Object(); thumbBounds = thumbContainer.getBounds(this); thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); private function setScrolling(me:MouseEvent):void { thumbContainer.removeEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.addEventListener(Event.ENTER_FRAME, scrollThumbs); } private function scrollThumbs(e:Event):void { if(mouseX <= thumbBounds.x || mouseX thumbBounds.width || mouseX < thumbBounds.y || mouseX thumbBounds.height) { thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.removeEventListener(Event.ENTER_FRAME, scrollThumbs); } if(thumbContainer.x = 0) { thumbContainer.x = 0; } if(thumbContainer.x <= -842) { thumbContainer.x = -842; } var xdist:Number = new Number(); xdist = mouseX - 382; thumbContainer.x += Math.round(-xdist / 10); }

  • Having trouble plugging jQuery FullCalendar into Squarespace page

    - by ellenchristine
    When I test the fullcalendar widget locally, it works fine. However, when I try to integrate it with Squarespace, it doesn't show up. Here is what is in my head tag: <link rel='stylesheet' type='text/css' href='storage/scripts/fullcalendar.css' /> <script type='text/javascript' src='storage/scripts/jquery.js'></script> <script type='text/javascript' src='storage/scripts/fullcalendar.js'></script> <script type='text/javascript'> $(document).ready(function() { // page is now ready, initialize the calendar... $('#calendar').fullCalendar({ aspectRatio:2 }) }); </script> I have this in my body tag: <div id="calendar" style="width:500px; height:330px; background-color:#CCCCCC;"></div> The div displays but the calendar doesn't appear at all. I can't figure out why this isn't working! The calendar should definitely fit in the div space (at least it does locally). I've used jQuery with Squarespace before, and I don't see where my error is.

  • How can I create an automatically generated alteranate table row color ?

    - by UXdesigner
    Good day, I've been trying to make this CSS code work: table.mytable { margin: 0; padding: 0; border: 0; font-size: 0.8em; border-collapse: collapse; } table.mytable td, table.mytable th { width: auto; padding: 2px 4px; vertical-align: top; } table.mytable th { color: #fff; background:url(images/header-bg.gif); text-align: left; } table.mytable tr.alternateColor { background-color:#E9F3FC; } well, it works, if I do write it manually. But as the tables are going to be generated thru asp.NET (Aspx) , which is not manually created- I'd like my table to generate the alternate rows. I've been trying to make this work with Javascript, but I can't figure it out and I believe this is a good resource site. I've been using a manual table with Adobe Dreamweaver cs4 as a test, but I have to put the class of "alternatecolors" in order to make them appear, and I can't do this normally.: Question is , can someone provide me a good Javascript that I would put in the header of the file, and actually help me out to make this work ? I think I'm burned...or maybe I can't see what others see quickly due to the amount of time I've spent. I just tried posting the code of my table here, but I couldn't get it well formatted and I got to run... I'm not using an 'id' on this table, but the class is 'mytable'. Thank you so much for your good help.

  • Adding a selection box into an ItemsControl?

    - by Jens
    I have a WPF ItemsControl with a Canvas ItemPanel. Drawing from an internal source, it displays lots of automatically generated Rectangles. As of now, it looks like this: <Window // .. NameSpaces > <Window.Resources> <DataTemplate x:Key="binTemplate"> <Rectangle x:Name="Rect" VerticalAlignment="Bottom" Canvas.Left="10" StrokeThickness="0"> // .. Databinding Height, Width, etc </Rectangle> </DataTemplate> </Window.Resources> <DockPanel x:Name="LayoutRoot" LastChildFill="True"> <ItemsControl ItemsSource="{Binding Bins}" ItemTemplate="{StaticResource binTemplate}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Canvas MouseDown="Canvas_MouseDown" MouseMove="Canvas_MouseMove" MouseUp="Canvas_MouseUp"> <Rectangle x:Name="Selection" Canvas.Left="0" Canvas.Top="0" Visibility="Hidden" /> </Canvas> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DockPanel> </Window> I now try to implement a selection box, too.. well.. select my Rectangles. =) I tried just adding the box into the ItemsControl PanelTemplate, and controlling it with the Canvas mouse events, but it appears I am not allowed to do so. The error message is "Cannot explicitly modify Children collection of Panel used as ItemsPanel for ItemsControl. ItemsControl generates child elements for Panel." What is the preferred way to implement such behavior? I thought about overlaying another canvas (using negative Margin) and drawing the selection box in there, but that seems like a bad hack. Thanks in advance!

  • Show hide DIVs : jQuery

  • Undefined variable error when parsing json

    - by Ben Shelock
    I'm trying to parse the json grabbed from here. Basically what I do is iterate over the items, sort them, then display them. But I get an error saying data.data.children[i] is undefined. I can't think why it's doing it though? var json = 'http://www.reddit.com/reddits/mine/.json'; GM_xmlhttpRequest({ method: "GET", url: json, onload: reddits }); function reddits(response){ var txt = response.responseText; var data; var suggested = document.getElementById('suggested-reddits'); if(window.JSON && JSON.parse){ data = JSON.parse(txt); } else{ data = eval("("+txt+")"); } suggested.innerHTML += '<span>reddits you\'re subscribed to </span> <ul id="rsub"></ul>'; GM_addStyle('#rsub{width: 500px;}'); var reddits = new Array(); var rsub = document.getElementById('rsub'); for(i = 0; i <= data.data.children.length; i++){ var r = data.data.children[i].data.display_name; reddits.push(r); } sort(reddits); for(i = 0; i <= reddits.length; i++){ rsub.innerHTML += '<li><a href="#" onclick="set_sr_name(this); return false">' + reddits[i] + '</a></li>'; } }

  • Strings exported from a module have changed line breaks

    - by Jesse Millikan
    In a DrScheme project, I'm using a MrEd editor-canvas% with text% and inserting a string from a literal in a Scheme file. This results in an extra blank line in the editor for each line of text I'm trying to insert. I've tracked this down to the apparent fact that string literals from outside modules are getting extra line breaks. Here's a full example. The editor is irrelevant at this point, but it displays the result. ; test-literals.ss (module test-literals scheme (provide (all-defined-out)) (define exported-string "From another module with some more line breaks. ")) ; editor-test.ss (module editor-test scheme (require mred "test-literals.ss") (define w (instantiate frame% ("Editor Test" #f) )) (define c (instantiate editor-canvas% (w) (line-count 12) (min-width 400))) (define editor (instantiate text% ())) (send c set-editor editor) (send w show #t) (send editor erase) (send editor insert "Some text with some line breaks. ") (send editor insert exported-string)) And the result in the editor is Some text with some line breaks. From another module with some more line breaks. I've traced in and figured out that it's changing Unix line breaks to Windows line breaks when strings are imported from another module, but these display as double line breaks. Why is this happening and is there a way to stop it other than changing every imported string?

  • How do i make a allocation table?

    - by david
    I have build a grid of div's as playground for some visual experiments. In order to use that grid, i need to know the x and y coordinates of each div. That's why i want to create a table with the X and Y position of each div. X:0 & Y:0 = div:eq(0), X:0 Y:1 = div:eq(1), X:0 Y:2 = div:eq(2), X:0 Y:3 = div:eq(3), X:1 Y:0 = div:eq(4) etc.. What is the best way to do a table like that? Creating a OBJECT like this: { 00: 0, 01: 1, 02: 2, etc.. } or is it better to create a array? position[0][0] = 0 the thing is i need to use the table in multiple way's.. for example the user clicked the div nb: 13 what are the coordinates of this div or what is the eq of the div x: 12 y: 5. Thats how i do it right now: var row = 0 var col = 0 var eq = 0 c.find('div').each(function(i){ // c = $('div#stage') if (i !=0 && $(this).offset().top != $(this).prev().offset().top){ row++ col = 0 } $(this).attr({'row': row, 'col': col }) col++ }) I think it would be faster to build a table with the coordinates, instead of adding them as attr or data to the DOM. but i cant figure out how to do this technically. How would you solve this problem width JS / jQuery?

  • Wordpress display featured posts outside of loop

    - by Thomas
    Im new to WP and Im not real sure how to work with the loop. I am trying to display featured posts in the sidebar with this code: <?php query_posts('cat=5'); $url = get_permalink(); while(have_posts()){ the_post(); $image_tag = wp_get_post_image('return_html=true'); $resized_img = getphpthumburl($image_tag,'h=168&w=168&zc=1'); $title = $post->post_title; echo "<ul class='left_featured'>"; echo "<li><a href='"; echo $url; echo "'><img src='$resized_img' width='168' height='168' "; echo "'/></a></li>"; echo "<li><a href='"; echo $url; echo "'/>"; echo $title; echo "</a></li></ul>"; echo ""; }; ?> This gives me all sorts of crazy outputs, text from random posts, images, etc...Its supposed to output a list of images and titles for all of the posts in a certain category. Any help would be really appreciated. Oh yeah, I am using a plugin that resizes images on the fly, thats what the the wp_get_post_image/getphpthumburl business is.

  • Colorbox does not refresh its contents when I change URL

    - by Josef Sábl
    I am trying to make use of Colorbox on my webpage. One specific feature does not work as expected, though. In their example (Outside Webpage - Iframe specifically) Google appears in the Colorbox when clicked. When you change href on that link (Using Firebug or JavaScript, e.g.) to, let's say, Yahoo, it works as expected and Yahoo is displayed after click. But not in my case. Once I click the link, I have no way to change the URL. Href, as displayed in browser, changes (to Yahoo), but click always opens the first page (Google). What might be the problem? I almost copy-pasted their example: <script src="/lib/jquery.js"></script> <script src="/lib/jquery.colorbox.js"></script> <p><a class='example7' href="http://yahoo.com">Outside Webpage (Iframe)</a></p> <script> $(document).ready(function(){ $(".example7").colorbox({width:"80%", height:"80%", iframe:true}); }); </script> My jquery version is 1.4.1 but I also tried same version as their example uses (1.3.2)

  • TinyMce imagemanager won't generate image path when used with an iframe

    - by Tom
    I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

  • 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.

  • 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

  • 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?

  • Jquery if statement help

    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.

  • Preserving SCRIPT tags (and more) in CKEditor

    - by Jonathan Sampson
    Update: I'm thinking the solution to this problem is in CKEDITOR.config.protectedSource(), but my regular-expression experience is proving to be too juvenile to handle this issue. How would I go about exempting all tags that contain the 'preserved' class from being touched by CKEditor? Is it possible to create a block of code within the CKEditor that will not be touched by the editor itself, and will be maintained in its intended-state until explicitly changed by the user? I've been attempting to input javascript variables (bound in script tags) and a flash movie following, but CKEditor continues to rewrite my pasted code/markup, and in doing so breaking my code. I'm working with the following setup: <script type="text/javascript"> var editor = CKEDITOR.replace("content", { height : "500px", width : "680px", resize_maxWidth : "680px", resize_minWidth : "680px", toolbar : [ ['Source','-','Save','Preview'], ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'], ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'], ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'], ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'], ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'], ['Link','Unlink','Anchor'], ['Image','Table','HorizontalRule','SpecialChar'] ] }); CKFinder.SetupCKEditor( editor, "<?php print url::base(); ?>assets/ckfinder" ); </script> UPDATE: I suppose the most ideal solution would be to preserve the contents of any tag that contains class="preserve" enabling much more than the limited exclusives.

  • How to disable other touch gestures after adding another tap gesture to the view?

    - by Hudson Duan
    I have a view with some tables and buttons on it, and then I want to add a tap gesture to the entire view, but I only want that gesture recognizer to recognize taps. Ideally, I want to do something when the added gesture recognizer is tapped, then remove that gesture recognizer after so the other buttons and tables can be accessed. Basically a tap to dismiss functionality that replicates something like the facebook notifications window, tap outside to dismiss, but not interfere with the buttons outside of the notifications view. Can anybody help? My current code is: NotificationsWindow *customView = [[[NSBundle mainBundle]loadNibNamed:@"NotificationsWindow" owner:self options:nil]objectAtIndex:0]; customView.frame= CGRectMake(12, 12, customView.frame.size.width, customView.frame.size.height); UITapGestureRecognizer *recognizerForSubView = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehindAgain:)]; [recognizerForSubView setNumberOfTapsRequired:1]; recognizerForSubView.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [customView addGestureRecognizer:recognizerForSubView]; [self.view addSubview:customView]; UITapGestureRecognizer *recognizerForSuperView = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)]; [recognizerForSuperView setNumberOfTapsRequired:1]; recognizerForSuperView.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [customView.superview addGestureRecognizer:recognizerForSuperView]; (void)handleTapBehind:(UITapGestureRecognizer *)sender { NSLog(@"tapped"); [[self.view.subviews lastObject] removeFromSuperview]; [self.view removeGestureRecognizer:sender]; } I want to make it so that the recognizer for the super view dismisses the subview, but not to interfere with the other taps on the super view.

  • 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.

  • Perl+Image::Magick usage: how to assemble several areas in one image into a new image?

    - by Jin
    Hi Everybody, I'm new to ImageMagick and haven't figured out how to assemble several areas into a new image. E.g., I know the "geometry" of words "hello" and "world" respectively in an image, what I need to do is to retrieve the word images and put then into one line image while keep their relative positions. Question1: Suppose I use the perl API, how should I use Composite() or other correct methods to do this? my $geom = sprintf('%dx%x+%d+%d', $word->{width}, $word->{height}, $offsetx, $offsety); $x = $lineimg->Composite($wordimg, $geom); warn "$x" if "$x"; Suppose $lineimg's size is big enough to hold all word images and the geometry has been computed. This code gives out a complain by ImageMagick: Exception 410: composite image required `Image::Magick' @ Magick.xs/XS_Image__Magick_Mogrify/7790 ... Question2: currently I only know how to crop a word image out of the original one and then Clone() method to restore the original image. Is there a way to copy instead of crop a specific area from a image? This way can save the time to copy back and forth the whole image several times. Does anybody know how to write this kind of processing? I appreciate all your help and suggestions! -Jin
