  • Unable to run jQuery Masonry in a Sencha Touch 2 app

    - by torr
    In my ST2 app I have on index.html <script id="jquery" type="text/javascript" src="resources/js/jquery-1.8.2.js"></script> <script id="masonry" type="text/javascript" src="resources/js/masonry-2.1.5.js"></script> as well as <script> $(document).ready(function(){ var $container = $('.x-list-container'); $container.imagesLoaded(function(){ $container.masonry({ itemSelector: '.x-list-item', }); }); }); </script> My front page on the app is a list so it wraps elements as such <div class="x-list-container"> <div class="x-list-item"></div> // 'x-list-item' is the block I want to float <div class="x-list-item"></div> ... </div> However once everything is loaded and I inspect .x-list-item there is no style positioning the div. I am experience with Masonry on regular web app but can;t make it work here. It's like Masonry isn't running at all. It is being loaded (checked on the network tab) and jQuery is being loaded (on network tab and tested using if (jQuery) {alert('hey there');. Any idea what I'm doing wrong? }

  • Has any one used client_side_validations gem with Chosen.js dropdown?

    - by Abid
    I am using chosen.js (http://harvesthq.github.com/chosen/). I was wondering if anyone has been able to use chosen select boxes and client_side_validations together. The issue is that when we use chosen it hides the original select element and renders its own dropdown instead, and when we focus out the validation isn't called and also when the validation message is shown it is shown with the original select element so positioning of the error isnt also correct. What could be a good way to handle this, My be we can change some code inside ActionView::Base.field_error_proc which currently looks something like ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| unless html_tag =~ /^<label/ %{<div class="field_with_errors">#{html_tag}<label for="#{instance.send(:tag_id)}" class="message">#{instance.error_message.first}</label></div>}.html_safe else %{<div class="field_with_errors">#{html_tag}</div>}.html_safe end end Any ideas ? Edit 1: I have the following solution that is working for me now. applied a class "chzn-dropdown" to all my selects that were being displayed by chosen used the following callback provided by client_side_validations Gem clientSideValidations.callbacks.element.fail = function(element, message, callback) { if (element.data('valid') !== false) { if(element.hasClass('dropdown')){ chzn_element = $('#'+element.attr('id')+'_chzn'); console.log(chzn_element); chzn_element.append(""+message+""); } else{ callback(); } } } Thanks

  • GWT Animation final value is not respected

    - by brad
    I have a FlowPanel that I'm trying to animate back and forth like an iphone nav. (See this post for my original question on how to do this) So I have it "working" with the code shown below. I say working in quotes because I'm finding that my final position of my scroller is not precise and always changes when scrolling. The GWT.log always says the actual values I'm looking for, so for instance with the call below to scrollTo, my GWT.log says: ScrollStart: 0 scrollStop: -246 But when I actually analyze the element in fireBug, its css, left position is never exactly -246px. Sometimes it's off by as much as 10px so my panel has just stopped scrolling before being finished. The worst part is that this nav animates back and forth, so subsequent clicks can really throw it off, and I need pixel perfect positioning otherwise the whole things looks off. I don't even know where to start with debugging this other than what I've already done. Any tips are appreciated. Code to call animation scroller = new Scroller(); scroller.scrollTo(-246,400); Animation Code public class Scroller extends Animation { private FlowPanel scroller; private final Element e; public Scroller(){ scroller = new FlowPanel(); e = scroller.getElement(); } public void scrollTo(int position, int milliseconds) { scrollStart = e.getOffsetLeft(); scrollStop = position; GWT.log("ScrollStart: " + scrollStart + " scrollStop: " + scrollStop); run(milliseconds); } @Override protected void onUpdate(double progress) { double position = scrollStart + (progress * (scrollStop - scrollStart)); e.getStyle().setLeft(position, Style.Unit.PX); } }

  • Png image processing in .NET.

    - by Oybek
    I have the following task. Take a base image and overlay on it another one. The base image is 8b png as well as overlay. Here are the base (left) and overlay (right) images. Here is a result and how it must look. The picture in the left is a screenshot when one picture is on top of another (html and positioning) and the second is the result of programmatic merging. As you can see in the screenshot the borders of the text is darker. Also here are the sizes of the images Base image 14.9 KB Overlay image 6.87 KB Result image 34.8 KB The size of the resulting image is also huge Here is my code that I use to merge those pictures /*...*/ public Stream Concatinate(Stream baseStream, params Stream[] overlayStreams) { var @base = Image.FromStream(baseStream); var canvas = new Bitmap(@base.Width, @base.Height); using (var g = canvas.ToGraphics()) { g.DrawImage(@base, 0, 0); foreach (var item in overlayStreams) { using (var overlayImage = Image.FromStream(item)) { try { Overlay(@base, overlayImage, g); } catch { } } } } var ms = new MemoryStream(); canvas.Save(ms, ImageFormat.Png); canvas.Dispose(); @base.Dispose(); return ms; } /*...*/ /*Tograpics extension*/ public static Graphics ToGraphics(this Image image, CompositingQuality compositingQuality = CompositingQuality.HighQuality, SmoothingMode smoothingMode = SmoothingMode.HighQuality, InterpolationMode interpolationMode = InterpolationMode.HighQualityBicubic) { var g = Graphics.FromImage(image); g.CompositingQuality = compositingQuality; g.SmoothingMode = smoothingMode; g.InterpolationMode = interpolationMode; return g; } My questions are What should I do in order to merge images to achieve the result as in the screenshot? How can I lower the size of the result image? Is the System.Drawing a suitable tool for this or is there any better tool for working with png for .NET?

  • Is it bad use "display: table;" to organise a layout into 2 columns?

    - by Colen
    Hello, I am trying to make a 2 column layout, apparently the bane of CSS. I know you shouldn't use tables for layout, but I've settled on this CSS. Note the use of display: table etc. div.container { width: 600px; height: 300px; margin: auto; display: table; table-layout: fixed; } ul { white-space: nowrap; overflow: hidden; display: table-cell; width: 40%; } div.inner { display: table-cell; width: auto; } With this layout: <div class="container"> <ul> <li>First</li> <li>Second</li> <li>Third</li> </ul> <div class="inner"> <p>Hello world</p> </div> </div> This seems to work admirably. However, I can't help wondering - am I obeying the letter of the "don't use tables" rule, but not the spirit? I think it's ok, since there's no positioning markup in the HTML code, but I'm just not sure about the "right" way to do it. I can't use css float, because I want the columns to expand and contract with the available space. Please, stack overflow, help me resolve my existential sense of dread at these pseudo-tables.

  • How to display only one letter in Flex Text Layout Framework ContainerController?

    - by rattkin
    I'm trying to implement dropped initials feature into my Flex application. Since Text Layout Framework does not support floating, the only known solution is to create additional containers that will be linked together, displaying the same textflow. Width and positioning of these containers has to be set in such a way that it will pretend that it's float. I'm using the same solution for dropped initials. Basically, I'm creating three containers, one for the initial letter (first letter in text flow), the other for text floating around, and the 3rd one to display text below these two. All these containers share one textflow. I have big issues with forcing controller to display only one letter from the text flow, and size it accordingly, so that it wont take any unnecessary aditional space and won't get any more text into it. Using ContainerController.getContentBounds() returns me size of whole sprite of the letter (with ascent/descent empty parts), not the height/width of the actual rendered letter. I'm using textFlow.flowComposer.getLineAt(0).getTextLine().getAtomBounds(0), but i think it's still not right. Also, even if I set container for this dimensions, it sometimes display additional text in it, especially for bigger fonts. See screen : Also, if I set width to just 1px less that contentBounds, things are going crazy, containers are moved around, positioned with big margins, etc. How should I solve this? Is it a bug in TLF / Player? Can I fix it somehow? Can I detect the size of the letter, or make containercontroller autosize to fit just one letter only?

  • Overlapping 2 Flash objects and controlling z-index

    - by Magnus Smith
    I have two Flash objects on a webpage (call them A and B), and they overlap so one partially obscures the other. I don't seem to have any control over the z-index, to force B in front of A. Whatever I try, A always 'wins' and stays on the top! I have read many people's posts about problem with getting HTML to show over the top of Flash...but nothing about when your two overlapping items are both Flash objects. I have tried various combinations of wmode=opaque/transparent/window I have tried CSS position:absolute/relative and z-index:0/999 I have tried placing the HTML sections in a different order The problem is the same in IE6 and Firefox 2.0 I do not want to use jQuery in this case In my particular situation B must have position:absolute and wmode=transparent, and sit above A. A needs relative positioning and transparency is not required. However, I have been testing without these restrictions, and I still have no control over the overlap. Are some SWFs (ours are adverts sent by clients) created in such a way as to override any code control of z-index? Thanks for any advice you can give.

  • How do I perform a flip and grow animation like in iPhoto 09?

    - by Austin
    I'm developing a Cocoa application and want to be able to click a button in one of the views in my NSCollectionView and have a details view flip open and position to the middle of the screen like it does in iPhoto 09 when you click the "i" in the bottom-right hand corner of a photo. The photo "flips" and grows, centered on the window to reveal details about the photo. I'm guessing they're using Core Animation to achieve this. I've been looking at the Lemur Flip example, but when I try to modify it to add repositioning code to the animation, it throws off the flip. Here is the positioning code I've added to the - (IBAction)flip:(id)sender; code of LemurFlip: ... [CATransaction begin]; { NSSize supersize = contentView.frame.size; // Size of window content view NSSize subsize = frontView.frame.size; // Size of view we're flipping out if(!frontView.isHidden) { // Move views to middle of the window [[backView animator] setFrameOrigin:NSMakePoint((supersize.width / 2) - (subsize.width / 2), (supersize.height / 2) - (subsize.height / 2))]; [[frontView animator] setFrameOrigin:NSMakePoint((supersize.width / 2) - (subsize.width / 2), (supersize.height / 2) - (subsize.height / 2))]; } else { // Return views to point of origin [[backView animator] setFrameOrigin:NSMakePoint(0, 0)]; [[frontView animator] setFrameOrigin:NSMakePoint(0, 0)]; } [hiddenLayer addAnimation:[self _flipAnimationWithDuration:flipDuration isFront:NO] forKey:@"flipGroup"]; [visibleLayer addAnimation:[self _flipAnimationWithDuration:flipDuration isFront:YES] forKey:@"flipGroup"]; } [CATransaction commit]; ... Is there a good example of how to do this or some rules for combining these sort of animations?

  • Android Compass orientation on unreliable (Low pass filter)

    - by madsleejensen
    Hi all Im creating an application where i need to position a ImageView depending on the Orientation of the device. I use the values from a MagneticField and Accelerometer Sensors to calculate the device orientation with SensorManager.getRotationMatrix(rotationMatrix, null, accelerometerValues, magneticFieldValues) SensorManager.getOrientation(rotationMatrix, values); double degrees = Math.toDegrees(values[0]); My problem is that the positioning of the ImageView is very sensitive to changes in the orientation. Making the imageview constantly jumping around the screen. (because the degrees change) I read that this can be because my device is close to things that can affect the magneticfield readings. But this is not the only reason it seems. I tried downloading some applications and found that the "3D compass" application remains extremely steady in its readings, i would like the same behavior in my application. I read that i can tweak the "noise" of my readings by adding a "Low pass filter", but i have no idea how to implement this (because of my lack of Math). Im hoping someone can help me creating a more steady reading on my device, Where a little movement to the device wont affect the current orientation. Right now i do a small if (Math.abs(lastReadingDegrees - newReadingDegrees) > 1) { updatePosition() } To filter abit of the noise. But its not working very well :)

  • performSelector:withObject:afterDelay: not working from scrollViewDidZoom

    - by oldbeamer
    Hi all, I feel like I should know this but I've been stumped for hours now and I've run out of ideas. The theory is simple, the user manipulates the zoom and positioning in a scrollview using a pinch. If they hold that pinch for a short period of time then the scrollview records the zoom level and content offsets. So I thought I'd start a performSelector:withObject:withDelay on the scrollViewDidZoom delegate method. If it expires then I record the settings. I delete the scheduled call every time scrollViewDidZoom is called and when the pinch gesture finishes. This is what I have: - (void)scrollViewDidZoom:(UIScrollView *)scrollView{ NSLog(@"resetting timer"); [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(positionLock) object:nil]; [self performSelector:@selector(positionLock) withObject:nil afterDelay:0.4]; } -(void)positionLock{ NSLog(@"position locked "); } - (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale{ NSLog(@"deleting timer"); [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(positionLock) object:nil]; } This is the output: 2010-05-19 22:43:01.931 resetting timer 2010-05-19 22:43:01.964 resetting timer 2010-05-19 22:43:02.231 resetting timer 2010-05-19 22:43:02.253 resetting timer 2010-05-19 22:43:02.269 resetting timer 2010-05-19 22:43:02.298 resetting timer 2010-05-19 22:43:05.399 deleting timer As you can see the delay between the last and second last events should have been more than enough for the delayed selector call to execute. If I replace performSelector:withObject:withDelay with plain old performSelector: I get this: 2010-05-19 23:08:30.333 resetting timer 2010-05-19 23:08:30.333 position locked 2010-05-19 23:08:30.366 resetting timer 2010-05-19 23:08:30.367 position locked 2010-05-19 23:08:30.688 deleting timer Which isn't what I want but serves to show that it's only the delay that's causing it to not function, not something to do with the selector not being declared in the header, being misspelt or any other reason. Any ideas as to why it's not working?

  • Inconsistent Frame / Bounds of UIImage and UIScrollView

    - by iFloh
    this one puzzles me. I have an Image with a width of 1600 pixels and height of 1819 pixels. I load the image as UIImageView into an UIScrollView and set the "contentsize parameter" iKarteScrollView.contentSize = CGSizeMake(iKarteImageView.bounds.size.width, iKarteImageView.bounds.size.height); NSLog(@"Frame - width %.6f, height %.6f - Bounds - width %.6f, height %.6f", myImageView.frame.size.width, myView.frame.size.height, myImageView.bounds.size.width, myImageView.bounds.size.height); NSLog(@"Content size width %.6f, height %.6f", myScrollView.contentSize.width, myScrollView.contentSize.height); The NSLog shows the following: Frame - width 1600.000000, height 1819.000000 - Bounds - width 1600.000000, height 1819.000000 Content size width 1600.000000, height 1819.000000 Now comes the miracle, in a subsequent method of the same object I call the same NSLog again. But this time the result is Frame - width 405.000000, height 411.000000 - Bounds - width 1601.510864, height 1625.236938 Content size width 404.617920, height 460.000000 Why is the frame size suddely 405 by 411 pixels? How can the Bounds be 1601 by 1625 where 1625 is roughly 200 pixels less than the original size? When Positioning a further UIImageView at the coordinates of 20 by 1625, the UIImageView is displayed an estimated 200 pixels above the bottom of the content of the UIScrollView. I'm lost ...

  • Drawing an honeycomb with as3

    - by vitto
    Hi, I'm trying to create an honeycomb with as3 but I have some problem on cells positioning. I've already created the cells (not with code) and for cycled them to a funcion and send to it the parameters which what I thought was need (the honeycomb cell is allready on a sprite container in the center of the stage). to see the structure of the cycle and which parameters passes, please see the example below, the only thing i calculate in placeCell is the angle which I should obtain directly inside tha called function Note: the angle is reversed but it isn't important, and the color are useful in example only for visually divide cases. My for cycle calls placeCell and passes cell, current_case, counter (index) and the honeycomb cell_lv (cell level). I thought it was what i needed but I'm not skilled in geometry and trigonometry, so I don't know how to position cells correctly: function placeCell (cell:Sprite, current_case:int, counter:int, cell_lv:int):void { var margin:int = 2; var angle:Number = (360 / (cell_lv * 6)) * (current_case + counter); var radius:Number = (cell.width + margin) * cell_lv; cell.x = radius * Math.cos (angle); cell.y = radius * Math.sin (angle); trace ("LV " + cell_lv + " current_case " + current_case + " counter " + counter + " angle " + angle + " radius " + radius) } how can I do to solve it?

  • Getting element position in IE versus other browsers

    - by Channel72
    We all know IE6 is difficult. But there seems to be disparate behavior in positioning in later versions of IE as well, when compared with Firefox or other browsers. I have a simple pair of javascript functions which finds the position of an element, and then displays another element in relation to the first element. The idea is to get the second element, which is somewhat larger, to appear in front of the first element when the mouse hovers over it. It works fine, except on all versions of Internet Explorer, the position of the second element appears different than in Firefox. The code to get the position of an element is: function getPosition(e) { var left = 0; var top = 0; while (e.offsetParent) { left += e.offsetLeft; top += e.offsetTop; e = e.offsetParent; } left += e.offsetLeft; top += e.offsetTop; return {x:left, y:top}; } And the actual rollover display code is: var pos = getPosition(elem1); elem2.style.top = pos.y - 8; elem2.style.left = pos.x - 6; In Firefox, elem2 appears directly over elem1, as I want it to. But in IE7 or IE8 it appears way off. What is the reason this occurs, and is there a way to fix it?

  • What makes good web form styling for business applications?

    - by ProfK
    Styling forms (form elements) is something that even Eric Meyer prefers to avoid. However, most business forms, and that is where styling is at issue; 'contact us' forms are easy to style, put window estate at a premium, with more 'document level' (e.g. invoice) fields, plus 'detail level' (e.g. invoice line) fields. Factors I often find at play are: At my minimum, at least two horizontally adjacent fieldsets are required. In applications vs. public web pages, fixed positioning vs fluid layout is often better. Quantity of content is important, vs. exaggerated readability. Users know the system, and cues etc. take a back seat. In light of factors like these, is there any available guidence for styling web form based applications? Are there any CSS or JavaScript frameworks that would make my quest to style these applications better than Visual Studios still pathetic 'Auto-format' (what drugs were those people on? I will never take them.)

  • calculate camera up vector after glulookat()?

    - by carrots
    I'm just starting out teaching myself openGL and now adding openAL to the mix. I have some planets scattered around in 3D space and when I touch the screen, I'm assigning a sound to a random planet and then slowly and smoothly flying the "camera" over to look at it and listen to it. The animation/tweening part is working perfectly, but the openAL piece isn't quiet right. I move the camera around by doing a tiny translate() and gluLookAt() for every frame to keep things smooth (tweening the camera position and lookAt coords). The trouble seems to be with the stereo image I'm getting out of the headphones.. it seems like the left/right/up/down is mixed up sometimes after the camera rolls or spins. I am pretty sure the trouble is here: ALfloat listenerPos[]={camera->currentX,camera->currentY,camera->currentZ}; ALfloat listenerOri[]={camera->currentLookX, camera->currentLookY, camera->currentLookZ, 0.0,//Camera Up X <--- here 0.1,//Camera Up Y <--- here 0.0}//Camera Up Z <--- and here alListenerfv(AL_POSITION,listenerPos); alListenerfv(AL_ORIENTATION,listenerOri); I'm thinking I need to recompute the UP vector for the camera after each gluLookAt() to straighten out the audio positioning problem.. but after hours of googling and experimenting I'm stuck in math that suddenly got way over my head. 1) Am I right that I need to recalculate the up vector after each gluLookAt() i do? 2) If so, can someone please walk me though figuring out how to do that?

  • Why not put all braces inline in C++/C#/Java/javascript etc.?

    - by DanM
    Of all the conventions out there for positioning braces in C++, C#, Java, etc., I don't think I've ever seen anyone try to propose something like this: public void SomeMethod(int someInput, string someOtherInput) { if (someInput > 5) { var addedNumber = someInput + 5; var subtractedNumber = someInput - 5; } else { var addedNumber = someInput + 10; var subtractedNumber = someInput; } } public void SomeOtherMethod(int someInput, string someOtherInput( { ... } But why not? I'm sure it would take some getting used to, but I personally don't have any difficulty following what's going on here. I believe indentation is the dominant factor in being able to see how code is organized into blocks and sub-blocks. Braces are just visual noise to me. They are these ugly things that take up lines where I don't want them. Maybe I just feel that way because I was weened on basic (and later VB), but I just don't like braces taking up lines. If I want a gap between blocks, I can always add an empty line, but I don't like being forced to have gaps simply because the convention says the closing brace needs to be on its own line. I made this a community wiki because I realize this is not a question with a defined answer. I'm just curious what people think. I know that no one does this currently (at least, not that I've seen), and I know that the auto-formatter in my IDE doesn't support it, but are there are any other solid reasons not to format code this way, assuming you are working with a modern IDE that color codes and auto-indents? Are there scenarios where it will become a readability nightmare? Better yet, are you aware of any research on this?

  • asp.net mvc stand alone ascx control how do i link (css and js) most efficiently

    - by Julian
    Hi, I need some advice. I have developed some asp.net mvc web pages. Each page has a master and some ascx controls (between 2 - 6) embedded into it a js and css file. Up to now every thing was fine. In order to improve modularity, flexibility and testability the ascx's are now expected to be able to work as stand alone controls. (Each ascx has also got its own css and js files in some cases it has another control inside it) In order to meet this requirement we call the controller with the relevant parameters and it returns the ascx (partial) directly to the browser without all of the other parts of the original page . In order to get it to display correctly (css) and act correctly (js/jquery) all of the relevant files need to be added (as links or scripts eg. href="<%= ResolveUrl(styleSheet)%>") to the user control. This is "contradicting" the concept of positioning the files at the most logical place (could be the master page for example). How can I overcome this problem? Keep in mind that this is relevant for each "control" ascx file. Any thoughts will be appreciated.

  • Horizontally-centering an absolute position to match a relative position

    - by Chris Vandevelde
    I'm trying to make a div box, containing various elements, fixed at the top of the page once the page has been scrolled so that the box would normally be out of view, but scroll normally until that point (like the behaviour at http://perldoc.perl.org/perl.html). The conditionally-fixed part is pretty simple to implement (set the position to "fixed" once the user has scrolled past a certain point, and "static" once it's scrolled back up), but I'm having trouble with the positioning and dimensions; it screws up if I'm not specifying an absolute position (if I'm using % or "auto", rather than px, em, cm, etc.) or it, confusingly, left-aligns if the box is less than the width of the page. I can understand why, more or less, I'm just trying to fix it. My strategy right now is to have an invisible DIV hold the place of the box and use Prototype's clonePosition() function to hold its position, but it doesn't seem to work for some reason. Neither does copying the margin from one element to the other. Any ideas? Bonus points and eternal gratitude if you can come up with an idea that will adjust itself with the browser window (like auto margins) without setting an onresize event.

  • Align 3 images in a div , left-centre-right, uneven margin

    - by Adrian
    I could find a work around for this if I wanted but it seems wrong and am trying to learn to code in a neater way. Basically I have a div with 3 images in it, the div is 700px, and each image is 220px, So thats 660px with two 20px gaps left and right of the centre image, and the outside images going all the way to their end of the div. Is there a quicker way of doing this without setting up seperate ids for each image? .contentpictureblock { float:left; } .contentpictureblock img { margin-right:20px; } <div class="contentpictureblock"> <img src="http://..."> <img src="http://..."> <img src="http://..."> </div> Doing the above^ pushes the third image to the next line, which is understandable. I know I could always make seperate divs for each image, and adjust the margins for each one but Im just wondering is there a quicker one off overflow type command that I could apply to the above? It would mean the right margin would be on all the images but would have no effect on its positioning in the last image. Thanks for the help.

  • Algorithm for assigning a unique series of bits for each user?

    - by Mark
    The problem seems simple at first: just assign an id and represent that in binary. The issue arises because the user is capable of changing as many 0 bits to a 1 bit. To clarify, the hash could go from 0011 to 0111 or 1111 but never 1010. Each bit has an equal chance of being changed and is independent of other changes. What would you have to store in order to go from hash - user assuming a low percentage of bit tampering by the user? I also assume failure in some cases so the correct solution should have an acceptable error rate. I would an estimate the maximum number of bits tampered with would be about 30% of the total set. I guess the acceptable error rate would depend on the number of hashes needed and the number of bits being set per hash. I'm worried with enough manipulation the id can not be reconstructed from the hash. The question I am asking I guess is what safe guards or unique positioning systems can I use to ensure this happens.

  • How do I toggle CSS with jQuery?

    - by marcamillion
    I have the following code: $('#bc' + $.trim($this) + ' span.dashed-circle').css({ 'border' : '5px solid #000'}); That is triggered by a click.function(). I would like that to be a toggle - so when I click the element, it changes the border to what I have above...but when it is clicked again it disappears or rather sets the border to ' '. Thoughts? Edit: I should have been explicit...but I don't want to create a CSS class. The reason being is because when I do that, it messes up the formatting of the element being styled. I am sure that it is some small quirk somewhere that would fix it, but I am not interested in wading through the entire code base to fix little positioning issues with a new class. I would much rather just edit the css attribute directly - because it doesn't interfere with the layout. Edit2: Here is the jsfiddle of the code I am trying to edit. If you notice, I have the CSS attributes last. But how do I let that be toggled ? Edit3: If anyone is interested...the UI that this will be used in is for my webapp - http://www.compversions.com

  • DataGridView not displaying data in ToolStripControlHost

    - by jblaske
    I'm utilizing the code posted by Jesper Palm here: http://stackoverflow.com/questions/280891/make-user-control-display-outside-of-form-boundry /// <summary> /// A simple popup window that can host any System.Windows.Forms.Control /// </summary> public class PopupWindow : System.Windows.Forms.ToolStripDropDown { private System.Windows.Forms.Control _content; private System.Windows.Forms.ToolStripControlHost _host; public PopupWindow(System.Windows.Forms.Control content) { //Basic setup... this.AutoSize = false; this.DoubleBuffered = true; this.ResizeRedraw = true; this._content = content; this._host = new System.Windows.Forms.ToolStripControlHost(content); //Positioning and Sizing this.MinimumSize = content.MinimumSize; this.MaximumSize = content.Size; this.Size = content.Size; content.Location = Point.Empty; //Add the host to the list this.Items.Add(this._host); } } I've translated it to VB: Public Class PopupWindow Inherits System.Windows.Forms.ToolStripDropDown Private _content As System.Windows.Forms.Control Private _host As System.Windows.Forms.ToolStripControlHost Public Sub New(ByVal content As System.Windows.Forms.Control) Me.AutoSize = False Me.DoubleBuffered = True Me.ResizeRedraw = True Me._content = content Me._host = New System.Windows.Forms.ToolStripControlHost(content) Me.MinimumSize = content.MinimumSize Me.MaximumSize = content.MaximumSize Me.Size = content.Size content.Location = Point.Empty Me.Items.Add(Me._host) End Sub End Class It works great with a PictureBox showing its information. But for some reason I cannot get the DataGridView to display anything when it is in the popup. If I pull the grid out of the popup it displays all of its information fine. If I pause during debug, the grid shows that it has all the data in it. It's just not displaying anything. Does anybody have any ideas?

  • div with absolute position behind the normal flow

    - by vasion
    i am trying to get a div to be my background and am using absolute positioning to achieve it. everything works fine except for the fact that it appears above anything in the normal flow and fiddling with z-indexes does absolutely nothing. <div id="blind"> <div id="blindbackground"></div> <div id="blindcontainer"><div class="loader"><img class='loader' src="/img/loader.gif"/></div></div> <div id="blindclosecontainer"><img id='blindclose' src="/img/close.gif"/></div> </div> and this is the css: #blind{ position :absolute; width:100%; z-index: 2; border-bottom: 1px silver solid; } #blindclosecontainer{ text-align: right; } #blindbackground{ position:absolute; top:0; width:100%; height:100%; background-color: white; filter:alpha(opacity=60); opacity:0.6; } #blindcontainer{ margin:auto; width:500px; background-color: white; padding:10px; } .loader{ margin: auto; width:18px; margin-top:10px; margin-bottom: 5px; }

  • Tying in .addClass() with other functions?

    - by Anders H
    Assuming an accordion dropdown with the standard form of: <ul> <li> <a href="#">Main Element</a> <ul> <li> <a href="#">Dropdown Element</a> </li> </ul> </li> </ul> I'm using jQuery to expand when the parent element link is clicked: var $j = jQuery.noConflict(); function initMenus() { $j('ul.menu ul').hide(); $j.each($j('ul.menu'), function(){ $j('#' + this.id + '.expandfirst ul:first').show(); }); $j('ul.menu li a').click( function() { var checkElement = $j(this).next(); var parent = this.parentNode.parentNode.id; if($j('#' + parent).hasClass('noaccordion')) { $j(this).next().slideToggle('normal'); return false; } if((checkElement.is('ul')) && (checkElement.is(':visible'))) { if($j('#' + parent).hasClass('collapsible')) { $j('#' + parent + ' ul:visible').slideUp('normal'); } return false; } if((checkElement.is('ul')) && (!checkElement.is(':visible'))) { $j('#' + parent + ' ul:visible').slideUp('normal'); checkElement.slideDown('normal'); return false; } } ); } $j(document).ready(function() {initMenus();}); To add a class to the Main Element when clicked (aka the class is enabled anytime the dropdown is expanded) I'm trying to use .toggleClass(className) without luck, most likely to my positioning. Where can I add this element to get the desired effect?

  • JApplet behaving unexpectedly

    - by JohnW
    import java.awt.Graphics; import java.awt.Image; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JApplet; import javax.swing.Timer; public class CountingSheep extends JApplet { private Image sheepImage; private Image backgroundImage; private GameBoard gameBoard; private scoreBoard scoreBoard; public void init() { loadImages(); gameBoard = new GameBoard(sheepImage, backgroundImage); scoreBoard = new scoreBoard(); getContentPane().add(gameBoard); getContentPane().add(scoreBoard); } public void loadImages() { sheepImage = getImage(getDocumentBase(), "sheep.png"); backgroundImage = getImage(getDocumentBase(), "bg.jpg"); } } Update guys: Alright, first of all, thank you very much for all the help you've given so far (specifically creemam and Hovercraft Full of Eels), and your persistence. You've helped me out a lot as this is incredibly important (i.e. me passing my degree). The problem now is: The program works correctly when nothing but the GameBoard class is added to the JApplet, however, when I try to add the ScoreBoard class, both Panel classes do not show on the Applet. I'm guessing this is now down to positioning? Any ideas? EDIT: Gone back to the previously asked question Hovercraft, and found it was due to the layout of the contentPane and the order at with the components were added. Thanks to all of you so much. People like you make the development community a bit of alright.
