• GUI Design - Roleselection with two lists, selected roles on the right, or left list?

  - by subes

  Hi, image two lists for selecting roles for a new user creation in an administrator frontend. One list has all available roles in it and another has the selected roles in it. Between those lists are buttons to move elements from one list to another. Thus the layout is horizontal with [List] [Buttons] [List]. Now to the question: Should the selected elements be on the left, or the right list? Intuitively some people I asked say, that the selected elements have to be on the right list. But some other people follow some sort of guideline that says, that the more important stuff in a frontend has to be on the left side. Also they think the selected elements are more important than the non-selected and so the selected ones have to be on the left side. Whats your opinion?

• trying to fade out a top div on hover to reveal working links in text below using JQuery

  - by Heath

  I need to fade a div (and image) to reveal a div underneath (text with clickable links) using jQuery. <script> $(document).ready(function(){ $("img.a").hover( function() { $(this).stop().animate({"opacity": "0"}, "slow"); }, function() { $(this).stop().animate({"opacity": "1"}, "slow"); }); }); </script> Used the above code and all worked well, until I went to click the links. Seems the top hidden div is preventing me from doing so. Tried the replaceWith function and that allowed me to click the links too - but couldn't get it to go back to showing original div when I moused out. Also, bossman wants the transition to be gradual - like a fade... Any suggestions? Many thanks! Heath

• Graphics/Vision Interesting Topics

  - by Myx

  Hello: I would like to do an interesting project for a computer graphics course. I know that there is a lot of literature out there (i.e. SIGGRAPH conference papers). I have a very large range of interest with regard to computer graphics (i.e. image processing, 3D modeling, rendering, animation). However, I've only taken computer vision/graphics for 2 semesters and thus don't have too much background experience, except for the class projects that I had to do. I've been looking through SIGGRAPH papers trying to see if there is anything that will be of interest to me but the literature is extremely vast. I was wondering if anyone has any topic suggestions, anything interesting that you ran across that you could recommend. I would prefer to do something fun yet slightly challenging (not really interested in making a shooter game). If this question does not belong here, I apologize and please let me know where I should move it. Thanks!

• TTTabItem in three20 icon not working?

  - by Frank

  I have been trying to get TTTabItem to work with images. And I dug up that you can set the icon to an image file. This is my implemenation: TTTabItem *tab1 = [[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease]; tab1.icon = @"bundle://icon_eat_min.png"; filterBar.tabItems = [NSArray arrayWithObjects: tab1, nil]; [scrollView addSubview:filterBar]; However, my icon doesn't even appear. I even search through this group: http://groups.google.com/group/three20/browse_thread/thread/f879f6643... and override the rounded style. But I am just contemplating why would you have an something you can set and not have it work? or am i doing this badly

• Resizing a UIButton programmatically by maintaining a margin

  - by Oscar Del Ben

  Hello, I'm adding a UIButton to a tableView footer programmatically. This button has a left and right margin that is equal to the tableView margin: UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; deleteButton.frame = CGRectMake(10, 60, 300, 34); deleteButton.autoresizingMask = UIViewAutoresizingFlexibleWidth I'm adding autoresizingMask because I want to support rotation. However, it does not work as I want, as the button stretches all the way down to the right, as shown by the image below. Any idea how to fix it? If I remove the autosizing property then the margin is correct.

• Cinema4D XML scene not rendering texture

  - by George Profenza

  I was playing with the Cinema 4D command line options and ran into a problem that might not be specific to the command line options. I saved a basic scene(a textured cube) in two formats: the original .c4d(binary) format and .xml(Cinema 4D XML via File Export). the .c4d file renders with the texture applied, while the .xml file renders without the texture applied. I had a look at the xml file, and there is a node that holds a reference to the image used as texture, and there is another node which seems to store the pixels in xml. When I opened the .xml document in Cinema 4D, the document did store the material with the texture, but it was not applied to the object. Am I missing something when I export to XML ? How can I export a Cinema 4D XML that can render with the texture applied ?

• UITextView on iPad INCREDIBLY Slow

  - by Sj

  I have an NSMutableArray of custom views (that are pretty much 1 UITextView and 1 UILabel with a custom back ground image), these are created as they are need (I start with 2 (though the first one is only 2 UITextFields and the other is normal) of these). Now my issue here seems to be this: as soon as I try to edit any UITextView past the one in the 2nd view, it starts to run incredibly slow, not the app, just the textview. For example, as I type, the little blinky guy lags behind the text and when I click to copy/paste/cut/etc you can see the little balloon fly in from the upper left corner every time. I have run the static analyzer for leaks and come up with nothing and run it alongside some other the testing software in XCode and it does not appear to have any reason for this. Any help would be greatly appreciated.

• Django: tinyMCE and cross site javascript

  - by pistacchio

  Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

• Imagemagick command line in PHP

  - by charly

  Hello everyone, I've got the following two commands for imagemagick in the command line: convert in.png container-mask.png +matte -compose CopyOpacity -composite out.png composite container.png out.png -compose multiply final.png Those two commands include 3 files: in.png: the file that should be masked container-mask.png: the back/white mask of the areas of container.png where in.png should be visible container.png image that includes the container for in.png, the one that has been masked in black/white with container-mask.png Now the question is how to transpose this commands into PHP calls. I've played around quite a bit, but I can't make sense of the API at http://php.net/manual/en/book.imagick.php Thanks and Bests, Charly

• PHP getimagesize with ampersand in string creates errors

  - by RobHardgood

  I'm using the getimagesize function in PHP, and the path string contains an ampersand, which otherwise is fine. The page gives me errors where getimagesize() is called. Looking at the source code, though, I see the ampersand is being passed through as & rather than just & I presume this is causing errors because PHP doesn't need to convert it to the html tag in order to find the path, right? Here is the error: Warning: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory

• In an ASP.NET Web Site Project, what is the best option to manage modular widgets

  - by Juan Sagasti

  We are creating a modular Web Site Project and all the UI is based on simple html pages with javascript widgets. These widgets obtain the data from a WCF class located in the app_code folder. Each widget has 3 files [ js, css , cs] and an image directory: , and we want all these files to be located under the same directory, say: /widgets/mywidget/ The problem is that the .cs file needs to be in the app_code folder to be compiled dynamically and that would break our widget modularity forcing the installator to distribute the widget code in two places. One of the options is use compiled assemblies instead of .cs files and use Assembly.Load() or smthg similar to load them when needed. What other options do you see?

• Examples of networked Flash games

  - by videodnd

  Maybe I am asking the wrong questions, because I don't see any sample projects out there. I know Flash developers have done Kiosks and renovated arcade games. "Come on, we see Flash everywhere." Is there a sample project I could be pointed towards, it would be an ass-saver. Can I prepare my swf files like an image gallery and receive XML commands to load it? Where do I start? Flash/After Effects skills have got me through so far, but I need help!!! It would be fun if it wasn't so stressful. Criteria TCP/IP socket connection Flash package XML commands load swf file in to a container Additional Questions How do I prepare my Flash files and XML sheet to receive commands "any sample out there"? What about e.data, urlLoad, xmlSocket Class, XMLCP/IP XML socket connection to load Is binary or XML method better for loading and reloading swf files? Do I need Red5 or a media server? videoDnd, Ambitious Development Noob

• What's so bad about in-line CSS?

  - by ChessWhiz

  When I see website starter code and examples, the CSS is always in a separate file, named something like "main.css", "default.css", or "Site.css". However, when I'm coding up a page, I'm often tempted to throw the CSS in-line with a DOM element, such as by setting "float: right" on an image. I get the feeling that this is "bad coding", since it's so rarely done in examples. I understand that if the style will be applied to multiple objects, it's wise to follow "Don't Repeat Yourself" (DRY) and assign it to a CSS class to be referenced by each element. However, if I won't be repeating the CSS on another element, why not in-line the CSS as I write the HTML? The question: Is using in-line CSS considered bad, even if it will only be used on that element? If so, why? Example (is this bad?): <img src="myimage.gif" style="float:right" />

• Bitmapfontatlas cocos2d performance issue

  - by meboz

  This question was also asked in the cocos2d forums but they are a little slower than here. Hi, Im trying to resolve a performance issue in my game. I have all of my game images on the one spritesheet. I now have a score label for which i have generated a font file with the Hiero tool. Ideally I'd like to update my score label with the current score on every update. However there seems to be a significant performance hit when doing so, which i believe is the result of the game images texture and the font texture swapping each update. Can anyone suggest a way to avoid this? Possibly by combining the font images with the game images in the one image file to avoid the texture swapping? Cheers

• click li, go to next li

  - by steve

  Can't find a simple solution to this, I know it's easy and I've tried a few things but I can't quite get it to work. I'm currently working with a sidescrolling site and I want every time you click an image (contained in an li) it scrolls to the next li. I have jQuery plugin localscroll so it smoothly goes from one to the next, and that's working. I need to now write a code that triggers jQuery to utilize the localscroll function and go to the next li. Right now I have this, but I know it's not right: $(document).ready(function () { var gallery = $('.wrapper ul li') $(gallery).click(function() { $.localscroll().next(li); }); });

• How does one bind to a List<DataRow> collection in WPF XAML?

  - by Elan

  Using a DataTable or DataView, one can specify the binding in XAML for example as follows: <Image Source="{Binding Thumbnail}" /> In my case I have created a List collection of DataRow objects and the above is not working. This is my data source: List<DataRow> I could of course convert the List< to a DataTable, but I am curious if there was a way to specify the binding in XAML to access the "Thumbnail" column within the DataRow that is stored in a List< collection.

• C# Exception when retrieving rows from a datagrid in virtual mode

  - by JamesM

  Hi all, I keep getting an exception (see below) when I retrieve a list of rows from a Virtual Mode datagrid, this only happens when I have more rows than I can display on screen and it doesn't happen every time. Is there anything I'm missing with regards to virtual mode? Update The image below shows the problem, the index is now outside the list range. The reason for this is say I have 10 items and I hide 5 as they are not needed and I want to run some code on the 5 that are visible, there are now 5 items but the index of some maybe between 5-9, how can I re-index? When I have run some code on the visible 5 I then show the hidden 5 so I don't want to disgard these, I'd need to reindex again when they are all visible. Many thanks.

• transition of x-axis results in overflow

  - by peter

  First of all, no: this question is not about the (yet) ugly transition of the lines (I might open another one for that, though..). I'm displaying data in line charts and the user can select the time horizon. The x-axis then correspondingly transitions so as to fit to the changed time horizon. In attached image, e.g., the time horizon was 1 week and then I switched to 4 weeks. The number of ticks on the x-axis increases from 7 to 28, correspondingly. Question: How can I prevent the x-axis animation to display outside the svg container? As you can see, the additional dates fly in from the left and they are being animated far far outside the container. Any ideas? Right now, the transition works probably in the most simple way it could: // format for x-axis var xAxis = d3.svg.axis() .scale(x) .orient("bottom") .tickFormat(d3.time.format("%d.%m")) .ticks(d3.time.days, 1) .tickSubdivide(0); // Update x-axis svg.select(".x") .transition() .duration(500) .call(xAxis);
