  • How to adjust a JScrollPane to its contained JTree

    - by spuas
    Hello, here I have a swing size question: I have a JTree which is contained inside a JScrollPane (which is contained in a custom component which extends JXPanel from swingx, but I think that has nothing to do with this question). Doesn't matter how many rows the tree has, the scrollpane is always bigger (the tree is dinamic but not designed to have many rows) but what I would like is the JScrollPane to adjust to the tree initial height and then show the vertical scroll when some of the nodes are expanded. I have tried without setting any size at all, setting tree preferred size to null and setting scrollpane preferred size to null as well but nothing changes. I DO NOT WANT to set the size manually... Is there a way to do this? Thanks

  • jQuery .getJSON() Not Parsing All Objects

    - by Brad
    I'm using jQuery's .getJSON function to parse a set of search results from a Google Search Appliance. The search appliance has an xslt stylesheet that returns the results as JSON data, which I validated with both JSONLint and Curious Concept's JSON Formatter. According to FireBug, the full result set is returned from the XMLHTTPRequest, but I tried dumping the data (with jquery.dump.js) and it only ever parses back the first result. It does successfully get all the Google Search Protocol stuff, but it only ever sees one "R" object (or individual result). Has anybody had a similar problem with jQuery's .getJSON? I know it likes to fail silently if the JSON is not valid, but like I said, I validated the results with several validators and it should be good to go. Edit: Clicking this link will show you the JSON results returned for a search for the word "google": http://bigbird.uww.edu/search?client=json_frontend&proxystylesheet=json_frontend&proxyrefresh=1&output=xml_no_dtd&q=google jQuery only retrieves the first "R" object, even though all "R" objects are siblings.

  • mod_rewrite: Different rules on different domains, same www-root

    - by Johan
    I have 8 domainnames that point to the same www-root. If the main domain is accessed, you are pointed to index.php, and from there on, the URL's are like: index.php?p=contact etc. If, however, you access one of the other 7 domains, that point to different units, you are initially pointed to: index_local.php, and from there on it goes like: index_local.php?p=contact etc. As you may see these URL's are very ugly, can I use mod_rewrite in this scenario to make it so that index.php AND index_local.php never show up in URL? Is there any better way to do this than the way I'm pointing the user now with multiple domains in the same www-root?

  • How can I truncate the mangled C++ identifiers shown by GDB's disassemble command?

    - by Rhys Ulerich
    GDB's disassemble command is nice for short C identifiers, e.g. main. For long, mangled C++ identifiers the verbosity is overkill. For example, using icpc I see results like (gdb) disassemble 0x49de2f 0x49de5b Dump of assembler code from 0x49de2f to 0x49de5b: 0x000000000049de2f <_ZN5pecos8suzerain16fftw_multi_array6detail18c2c_buffer_processIPA2_dPKSt7complexIdEilNS2_26complex_copy_differentiateIS4_EEEEvT_T1_T2_T0_SD_SE_RKT3_+167>: mov 0x18(%rsp),%rsi Displays that long are annoying in the CLI. They make GDB's TUI assembly display all but useless. Is there a way to tell GDB to show a truncated identifier? Say clip all but 50 characters?

  • Where should document-related actions for a Cocoa app be implemented?

    - by Adam Preble
    I'm writing a document-based Cocoa app that's basically a graphical editing program. I want the user to be able to show/hide non-modal windows (such as an inspector window). Since these windows would be shown/hidden from menu items, where is the "best" place to implement the actions, such as - (IBAction)toggleInspector:(id)sender? I've seen that in the Sketch example code these are implemented in the app delegate, and the window controller instances are kept there as well, but that feels like more of a convenient place to put it than the most "graceful" place. Additionally, since this inspector would only be relevant when a document is open it feels like it should be associated more with the document's main NSWindowController than the app.

  • WordPress Monthly Archive by Year

    - by PaulDavis
    WordPress extraordinaires, I need your help! I need to be able to list the archives, but in a slightly different way than the WP codex, or an hour of Googling will show me. I need the months of the year, as the generic archive function, but only for one year at a time. So, list all the months in 2007. I'll need to be able to use this multiple times in the same template too, for different years. I've got a feeling query_posts might be the way, but I'm not too sure. Anyone got some ideas?

  • How to store images efficiently (memory-wise) while still being able to process them

    - by Sheeo
    I'm working on a silverlight project where users get to create their own Collages. The problem When loading images into memory, I'm using BitmapImage so that they can be displayed directly with the Image control--but they're locked in afterwards. So I've tried storing them seperately aswell, but that just sucks up huge amounts of RAM. So in short, is there a class that'll let me store JPEG images, be able to show them with the image control, and still be able to export it afterwards? All this needs to be efficient--i.e. I'd rather not want any copying to ARGB arrays or use the WriteableBitmap to copy them over. I require to work with large collections of images, up to 300 at most. Any help apreciated!

  • UISearchBar in UINavigationBar with ScopeBar

    - by ncipollina
    I am trying to put a UISearchBar inside of the UINavigationBar, which I am able to do without much problem. The problem is that I have logic when editing to show the Scope Bar. This all works fine, with one exception. The navigation bar tries to center the UISearchBar inside of the title view. This causes the search bar to move up above the navigation bar. I tried adding some logic to set the frame of the search bar so that it just draws overtop of my main view, which is fine. I can only set the height, which causes the search bar to draw over the view just fine, but it isn't wide enough to cover the whole screen. If I set the width on the frame, it goes back to the same behavior of trying to center the UISearchBar on the navigation bar. Anyone know how I can accomplish this? Thanks, Nick

  • Fire only one Custom Validator at a time

    - by Lijo
    I have two Custom Validators attached to a textbox. The textbox is to enter comma separated list of emails. The first validator checks that there is not duplicate email address. The second custom validator checks that all the email addresses are in valid format. I have following code and it works fine. However, when both the failure criteria is met both of them are firing and I get two * at the right side of my textbox. What is the best approach to show only one * at a time? CODE <asp:CustomValidator ID="valEmailRecipients" runat="server" ControlToValidate="txtEmailRecipients" ClientValidationFunction="isUniqueElements" OnServerValidate="IsUniqueEmail_Validate" Text="*" ErrorMessage="There should be no duplicate email address for a report" ValidationGroup="Save"> </asp:CustomValidator> <asp:CustomValidator ID="valEmailFormat" runat="server" ControlToValidate="txtEmailRecipients" ClientValidationFunction="checkEmailFormat" OnServerValidate="IsValidEmailFormat_Validate" Text="*" ErrorMessage="Entries should be valid email addresses separated by comma" ValidationGroup="Save"> </asp:CustomValidator> REFERENCES: Validating with a Custom Function for ASP.NET Server Controls

  • How to use FBJS to get the language preference of the user?

    - by ed.talmadge
    I'm modifying an existing FaceBook application. The FaceBook application is generated by another application, so I don't have much control over it. I can only add html/javascript. My goal is to use FBJS to detect the current language setting of the user and display a different message depending on their language. For example, if the user has their language setting set to Spanish, then I would like to show a message in Spanish on my FaceBook application. How can I do this?

  • How to make a form using ajax, onchange event, reload to SAME page

    - by user1348220
    I've been studying this for a while and I'm not sure if I'm going about this the right way because every form I setup according to examples, it doesn't do what I need. I need to setup a form that will: set session when you select from dropdown menu not reload/refresh page (i've read that using AJAX solves this) submit and stay on SAME page (confused because most AJAX examples send it to different process.php page which is supposedly "invisible" but it doesn't "stay" on the same page, it redirects. Basically, client selects quantity of 1 to 10. If they select "2"... it does NOT reload the page.. but it DOES set a session[quantity]=2. Should be simple... but do I POST to same page as form? or POST to different page and it somehow redirects? Also, one test I did it kept pasting my "echo session[quantity]" down the page like 7, 2, 3, 5, etc. etc. each time instead of replacing it. I would paste code but it's all over the place and I'm hoping for direction on which methods to use. Feel I need to start all over again. Edit: trying to add code below but can't seem to paste it properly. <? ob_start();?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <?php session_start(); ?> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Submit Form with out refreshing page Tutorial</title> <!-- JavaScript --> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script> <script type="text/javascript" > $(function() { $(".submit").click(function() { var gender = $("#gender").val(); var dataString = '&gender=' + gender; if(gender=='') { $('.success').fadeOut(200).hide(); $('.error').fadeOut(200).show(); } else { $.ajax({ type: "POST", url: "join.php", data: dataString, success: function(){ $('.success').fadeIn(200).show(); $('.error').fadeOut(200).hide(); } }); } return false; }); }); </script> <style type="text/css"> body{ } .error{ color:#d12f19; font-size:12px; } .success{ color:#006600; font-size:12px; } </style> </head> <body id="public"> <div style="height:30px"></div> <div id="container"> <div style="height:30px"></div> <form method="post" name="form"> <select id="gender" name="gender"> <option value="">Gender</option> <option value="male">Male</option> <option value="female">Female</option> </select> <div> <input type="submit" value="Submit" class="submit"/> <span class="error" style="display:none"> Please Enter Valid Data</span> <span class="success" style="display:none"> Your gender is <?php echo $_SESSION['gender'];?></span> </div> </form> <div style="height:20px"></div> </div><!--container--> </body> </html> <? ob_flush(); ?> and here is my page where the POST goes called join.php (called that in example so I went with it for now) <?php session_start(); if($_POST) { $gender = $_POST['gender']; $_SESSION['gender'] = $gender; } else { } ?>

  • VB.NET: Force user to use the topmost form

    - by SiliconCelery
    I'm programming a Minesweeper clone in Visual Studio 2010, with VB.NET, as a Windows Form Application, and I'm having trouble with the Game Won and Game Lost forms. When I show those forms, I want the game form to still be visible, so that the player can see where the mines were, but I don't want the game form to be enabled until the Game Won or Game Lost form is closed. Exactly like Windows Minesweeper does when you win or lose. There aren't any obvious properties for this, as far as I can see, and I've had no luck Googling, I don't know what terms to search. Any help is appreciated, thanks.

IE correctly shows PDFs generated by other websites, though. Don't know if it matters but the page is accessed through HTTPS. My controller does the following: renders the source page through mako converts the html to pdf using pisa adds these headers to the response: Content-type: application/pdf and Content-disposition: inline; filename=file.pdf Do you have any suggestion? I seem to be stuck and cannot think of anything else to try.

  • Export Failed Element Log(s) after deliver?

    - by cogmios
    When a deliver has been performed I can rightlick an entry in the GUI version/element log and it displays me a popup with the element log. Quite handy. I now have a delivery with about 25 failed ones and a couple of hundred OK's. Sadly I can not sort on the column "status" so I have to make screenshots wherever I find a [!] to sit together with the specific team to find out if it is really ok to not deliver those. It would however be handy to have this list of element logs from a deliver so that I do not have to make screenshots or copy the contents of the popup box one by one but just have a list of the failed ones with the element log. Is there a way to export the element logs from a deliver (so the the ones that show up when you rightclick and choose "Display Element Log") and/or only the ones that gave failures?
