  • _dl_runtime_resolve -- When do the shared objects get loaded in to memory?

    - by windfinder
    We have a message processing system with high performance demands. Recently we have noticed that the first message takes many times longer then subsequent messages. A bunch of transformation and message augmentation happens as this goes through our system, much of it done by way of external lib. I just profiled this issue (using callgrind), comparing a "run" of just one message with a "run" of many messages (providing a baseline of comparison). The main difference I see is the function "do_lookup_x" taking up a huge amount of time. Looking at the various calls to this function, they all seem to be called by the common function: _dl_runtime_resolve. Not sure what this function does, but to me this looks like the first time the various shared libraries are being used, and are then being loaded in to memory by the ld. Is this a correct assumption? That the binary will not load the shared libraries in to memory until they are being prepped for use, therefore we will see a massive slowdown on the first message, but on none of the subsequent? How do we go about avoiding this? Note: We operate on the microsecond scale.

  • Jquery dynamic button : how to bind to exisitng click event by class

    - by omer bach
    I have a click event triggered by the class selector inside the jquery ready scope: $(".testBtn").click(function() { alert("This Works"); }); This works fine for static buttons how ever this doesn't work for dynamic buttons which are added upon clicking the button with "addRowBtn" id. I'm guessing that it has something to do with that the button is created after the event is registered but still the new button has the 'testBtn' class so it makes sense it should work. Any idea what am i doing wrong and how to make the dynamic buttons registered to the class selector click event? Here is the whole code, you can copy and paste into an html, click the 'add button' and try to click the added buttons. you'll see nothing happens. <html> <head> <script src='http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js'></script> <script src='http://ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js'></script> <script> $(function() { $(".addRowBtn").click(function() { $("#mainTable tr:last").after("<tr><td><button class='testBtn'>NotWorking</button></td></tr>"); }); $(".testBtn").click(function() { alert("This Works"); }); }); </script> </head> <body> <table id="mainTable"> <button class="addRowBtn">Add button</button> <tr><th>Testing</th></tr> <tr><td><button class='testBtn'>Working</button></td></tr> </table> </body> </html>

  • Using a php://memory wrapper causes errors...

    - by HorusKol
    I'm trying to extend the PHP mailer class from Worx by adding a method which allows me to add attachments using string data rather than path to the file. I came up with something like this: public function addAttachmentString($string, $name='', $encoding = 'base64', $type = 'application/octet-stream') { $path = 'php://memory/' . md5(microtime()); $file = fopen($path, 'w'); fwrite($file, $string); fclose($file); $this->AddAttachment($path, $name, $encoding, $type); } However, all I get is a PHP warning: PHP Warning: fopen() [<a href='function.fopen'>function.fopen</a>]: Invalid php:// URL specified There aren't any decent examples with the original documentation, but I've found a couple around the internet (including one here on SO), and my usage appears correct according to them. Has anyone had any success with using this? My alternative is to create a temporary file and clean up - but that will mean having to write to disc, and this function will be used as part of a large batch process and I want to avoid slow disc operations (old server) where possible. This is only a short file but has different information for each person the script emails.

  • $.ajax not loading data data everytime from server

    - by Ted
    I have written a simple jQuery.ajax function which loads a user control from the server on click of a button. The first time I click the button, it goes to the server and gets me the user control. But each subsequent click of the same button does not goes to the server to fetch me the user control. Since my user control fetches data from db, I need to reload the user control everytime i hit the button. But if anyhow I get my user control to unload from the page, and re-click the button, it goes to the server and fetches me the user control. Here's the code: $("#btnLoad").click(function() { if ($(this).attr("value") == "Load Control") { $.ajax({ url: "AJAXHandler.ashx", data: { "lt": "loadcontrol" }, dataType: "html", success: function(data) { content.html(data); } }); $(this).attr("value", "Unload Control"); } else { $.ajax({ url: "AJAXHandler.ashx", data: { "lt": "unloadcontrol" }, dataType: "html", success: function(data) { content.html(data); } }); $(this).attr("value", "Load Control"); } }); Please let me know if there is any other way I can get my user control loaded from server everytime I click the button.

  • Interrupting Prototype handler, alert() vs event.stop()

    - by lxs
    Here's the test page I'm using. This version works fine, forwarding to #success: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html><head> <script type="text/javascript" src="prototype.js"></script> </head><body> <form id='form' method='POST' action='#fail'> <button id='button'>Oh my giddy aunt!</button> <script type="text/javascript"> var fn = function() { $('form').action = "#success"; $('form').submit(); } $('button').observe('mousedown', fn); </script> </form> </body></html> If I empty the handler: var fn = function() { } The form is submitted, but of course we are sent to #fail this time. With an alert in the handler: var fn = function() { alert("omg!"); } The form is not submitted. This is awfully curious. With event.stop(), which is supposed to prevent the browser taking the default action: var fn = function(event) { event.stop(); } We are sent to #fail. So alert() is more effective at preventing a submission than event.stop(). What gives? I'm using Firefox 3.6.3 and Prototype 1.6.0.3. This behaviour also appears in Prototype 1.6.1.

  • ArrayAccess multidimensional (un)set?

    - by anomareh
    I have a class implementing ArrayAccess and I'm trying to get it to work with a multidimensional array. exists and get work. set and unset are giving me a problem though. class ArrayTest implements ArrayAccess { private $_arr = array( 'test' => array( 'bar' => 1, 'baz' => 2 ) ); public function offsetExists($name) { return isset($this->_arr[$name]); } public function offsetSet($name, $value) { $this->_arr[$name] = $value; } public function offsetGet($name) { return $this->_arr[$name]; } public function offsetUnset($name) { unset($this->_arr[$name]); } } $arrTest = new ArrayTest(); isset($arrTest['test']['bar']); // Returns TRUE echo $arrTest['test']['baz']; // Echo's 2 unset($arrTest['test']['bar']; // Error $arrTest['test']['bar'] = 5; // Error I know $_arr could just be made public so you could access it directly, but for my implementation it's not desired and is private. The last 2 lines throw an error: Notice: Indirect modification of overloaded element. I know ArrayAccess just generally doesn't work with multidimensional arrays, but is there anyway around this or any somewhat clean implementation that will allow the desired functionality? The best idea I could come up with is using a character as a separator and testing for it in set and unset and acting accordingly. Though this gets really ugly really fast if you're dealing with a variable depth. Does anyone know why exists and get work so as to maybe copy over the functionality? Thanks for any help anyone can offer.

  • Highlight image borders with Ajax request.

    - by Tek
    First, some visualization of the code. I have the following images that are dynamically generated from jquery. They're made upon user request: <img id="i13133" src="someimage.jpg" /> <img id="i13232" src="someimage1.jpg" /> <img id="i14432" src="someimage2.jpg" /> <img id="i16432" src="someimage3.jpg" /> <img id="i18422" src="someimage4.jpg" /> I have an AJAX loop that repeats every 15 seconds using jQuery and it contains the following code: Note: The if statement is inside the Ajax loop. Where imgId is the requested ID from the Ajax call. //Passes the IDs retrieved from Ajax, if the IDs exist on the page the animation is triggered. if ( $('#i' + imgId ).length ) { var pickimage = '#i' + imgId; var stop = false; function highlight(pickimage) { $(pickimage).animate({color: "yellow"}, 1000, function () { $(pickimage ).animate({color: "black"}, 1000, function () { if (!stop) highlight(pickimage); }); }); } // Start the loop highlight(pickimage); } It works great, even with multiple images. But I had originally used this with one image. The problem is I need an interrupt. Something like: $(img).click(function () { stop = true; }); There's two problems: 1.)This obviously stops all animations. I can't wrap my head around how I could write something that only stops the animation of the image that's clicked. 2.)The Ajax retrieves IDs, sometimes those IDs appear more than once every few minutes, which means it would repeat the animations on top of each other if the image exists. I could use some help figuring out how to detect if an animation is already running on an image, and do nothing if the animation is already triggered on an image.

  • ExternalInterface issue on loadup with FireFox

    - by Rudy
    Hello, I have an issue with my ExternalInterface. The way it is currently set up is, on the page load up, a boolean is set to true in JavaScript and then checked by ActionScript constructors (using a timer) until it is true. This marks that JavaScript is ready to get calls from AS3. At this point, AS3 will add the callback and do some internal stuff, and at the end of the constructor I call JavaScript. So far so good. JavaScript will at this point call a function in AS3 (that was defined in the callback described above), and this is where it all messes up. On IE this works perfectly fine. On FireFox though, it does not. When I debug it, I see that the javascript function is called but when it tries to call AS3, nothing happens. I also tried to add a timer, but for some reason the function STILL executes straight away (in IE). What is very weird is that a second or two later, that function will work, so it seems that the Flash is not completely loaded in FireFox? But it runs to the last line of my constructor, so I would believe it's loaded. Any idea please, I am really stuck. Thanks a lot, Rudy

  • Trying to draw a dynamic rectangle in SVG

    - by Shaun
    To be more specific, here are the steps I need: onmousedown - set x and y of rect as mouse coordinates onmousemove - using the current x and y mouse coordinates calculate height and width of the rect, set these and append onmouseup - remove the rectangle, and call a function based off some calculations from the rect. Here is what I have but isn't quite working (right now I have it drawing a line to make it simpler): onmousedown: startbox(evt) function startbox(evt) { if(evt.button === 0) { x1 = evt.clientX + div.scrollLeft-5; y1 = evt.clientY + div.scrollTop-30; obj.setAttributeNS(null, "x1", x1); obj.setAttributeNS(null, "y1", y1); Root.setAttributeNS(null, "onmousemove", "updatebox(evt)"); } } onmousemove: updatebox(evt) function updatebox(evt) { if(evt.button === 0) { x2 = evt.clientX + div.scrollLeft-5; y2 = evt.clientY + div.scrollTop-30; Root.appendChild(.obj); w = Math.abs(x2-x1); h = Math.abs(y2-y1); var strokecolor; if(w>20 && h>20) { strokecolor = "green"; validbox = true; } else { strokecolor = "red"; validbox = false; } var Attr={ x2:x2, y2:y2, stroke:strokecolor } assignAttr(obj, Attr); //just loops thru adding multiple attributes } } onmouseup: endbox() function endbox(evt) { if(evt.button===0) { Root.setAttributeNS(null, "onmousemove", ""); Root.removeChild(obj); if(validbox) { //do stuff validbox = !validbox; } } } Some of my problems with this are: Its slow in Chrome making drawing the line/rect feel sluggish. It won't work two times in a row. This is the real problem that I can't fix. Any and all feedback is welcome.

  • How to define a "complicated" ComputedColumn in SQL Server?

    - by Slauma
    SQL Server Beginner question: I'm trying to introduce a computed column in SQL Server (2008). In the table designer of SQL Server Management Studio I can do this, but the designer only offers me one single edit cell to define the expression for this column. Since my computed column will be rather complicated (depending on several database fields and with some case differentiations) I'd like to have a more comfortable and maintainable way to enter the column definition (including line breaks for formatting and so on). I've seen there is an option to define functions in SQL Server (scalar value or table value functions). Is it perhaps better to define such a function and use this function as the column specification? And what kind of function (scalar value, table value)? To make a simplified example: I have two database columns: DateTime1 (smalldatetime, NULL) DateTime2 (smalldatetime, NULL) Now I want to define a computed column "Status" which can have four possible values. In Dummy language: if (DateTime1 IS NULL and DateTime2 IS NULL) set Status = 0 else if (DateTime1 IS NULL and DateTime2 IS NOT NULL) set Status = 1 else if (DateTime1 IS NOT NULL and DateTime2 IS NULL) set Status = 2 else set Status = 3 Ideally I would like to have a function GetStatus() which can access the different column values of the table row which I want to compute the value of "Status" for, and then only define the computed column specification as GetStatus() without parameters. Is that possible at all? Or what is the best way to work with "complicated" computed column definitions? Thank you for tips in advance!

  • Clearing input text feilds when clicked on in Flash (AS 2.0)

    - by rickstyphilis
    I have a problem where I want a text field that by default has the word NAME in it, to become empty when a user clicks on it. The text field has the instance name 'nam' and is inside a movie with the instance name 'input_text'. I've searched around and found samples of code where everyone keeps suggesting this: textboxinstancename.onSetFocus = function() { textboxinstancename.text = ""; }; should work. It seems to work for everyone else but me. I've tried using the following on the first frame of the 'input_text' movie with no luck: this.input_text.nam.onSetFocus = function() { this.input_text.nam.text = "" } I've tried putting this on the first frame of the scene, again with no result: _root.input_text.nam.onSetFocus = function() { _root.input_text.nam.text = "" } I've tried this in the same manner as the last respectively with both 'this' on the instance and '_root' on the scene (denoted by x): x.input_text.nam.onSetFocus = function() { if (x.input_text.nam.text == "NAME") { x.input_text.nam.text = ""; } }; Still no luck. Can anyone tell me what I might be doing wrong?

  • jQuery Cycle : Multiple Instances, detect end of each instance

    - by guylabbe.ca
    I am using multiple instances of Cycle for a portfolio; Only one is shown and the others are hidden. Each Cycle is a project with multiple images. The only thing I can't figure out is how to detect the end of the « current » Cycle instance. with after: function, it is triggered for all instances at once, impossible to get « local » events. Here is my code : $('.sldr_closeup').each(function() { var currId = $(this).attr('id'); window['num_'+currId] = 0; $(this).cycle({ timeout:0, speed:500, fx:'fade', next:'.nextimages', prev:'.previmages', fit:1, nowrap:1, autstop:0, after : function(c,n,o,f) { var currId = $(this).parent('div').attr('id'); (f) ? window['num_'+currId] ++ : window['num_'+currId] --; if ((o.slideCount == window['num_'+currId] )) { alert(currId); $('.nextimages').stop().fadeTo(400,0,function(){ if(currId != $('.projectList .projet').last().find('a').attr('rel')) $('.nextproject').stop().fadeTo(400,1); $(this).hide(); }); } } }).cycle('pause'); });

  • What's the boost way to create a functor that binds out an argument

    - by Mordachai
    I have need for a function pointer that takes two arguments and returns a string. I would like to pass an adapter that wraps a function that takes one argument, and returns the string (i.e. discard one of the arguments). I can trivially build my own adapter, that takes the 2 arguments, calls the wrapped function passing just the one argument through. But I'd much rather have a simple way to create an adapter on the fly, if there is an easy way to do so in C++/boost? Here's some details to make this a bit more concrete: typedef boost::function<CString (int,int)> TooltipTextFn; class MyCtrl { public: MyCtrl(TooltipTextFn callback = boost::bind(&MyCtrl::GetCellText, this, _1, _2)) : m_callback(callback) { } // QUESTION: how to trivially wrapper GetRowText to conform to TooltipTextFn by just discarding _2 ?! void UseRowText() { m_callback = boost::bind(&MyCtrl::GetRowText, this, _1, ??); } private: CString GetCellText(int row, int column); CString GetRowText(int row); TooltipTextFn m_callback; } Obviously, I can supply a member that adapts GetRowText to take two arguments and only passes the first to GetRowText() itself. But is there already a boost binder / adapter that lets me do that?

  • Scheme: what are the benefits of letrec?

    - by Ixmatus
    While reading "The Seasoned Schemer" I've begun to learn about letrec. I understand what it does (can be duplicated with a Y-Combinator) but the book is using it in lieu of recurring on the already defined function operating on arguments that remain static. An example of an old function using the defined function recurring on itself (nothing special): (define (substitute new old lat) (cond ((null? l) '()) ((eq? (car l) old) (cons new (substitute new old (cdr l)))) (else (cons (car l) (substitute new old (cdr l)))))) Now for an example of that same function but using letrec: (define (substitute new old lat) (letrec ((replace (lambda (l) (cond ((null? l) '()) ((eq? (car l) old) (cons new (replace (cdr l)))) (else (cons (car l) (replace (cdr l)))))))) (replace lat))) Aside from being slightly longer and more difficult to read I don't know why they are rewriting functions in the book to use letrec. Is there a speed enhancement when recurring over a static variable this way because you don't keep passing it?? Is this standard practice for functions with arguments that remain static but one argument that is reduced (such as recurring down the elements of a list)? Some input from more experienced Schemers/LISPers would help!

  • Validating age field

    Hi people, I'm trying to validate an age field in a form but I'm having some problem. First I tried to make sure that the field will not be send empty. I don't know JavaScript so I searched some scripts and adapted them to this: function isInteger (s) { var i; if (isEmpty(s)) if (isInteger.arguments.length == 1) return 0; else return (isInteger.arguments[1] == true); for (i = 0; i < s.length; i++) { var c = s.charAt(i); if (!isDigit(c)) return false; } return true; } function isEmpty(s) { return ((s == null) || (s.length == 0)) } function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt);return false; } else { return true; } } } function validate_form(thisform) { with (thisform) { if ((validate_required(age,"Age must be filled out!")==false) || isInteger(age,"Age must be and int number")==false)) {email.focus();return false;} } } //html part <form action="doador.php" onsubmit="return validate_form(this)" method="post"> It's working fine for empty fields, but if I type any letters or characters in age field, it'll be sent and saved a 0 in my database.

  • PEAR mail not sending to .eu email addresses

    - by andy-score
    I have a PEAR mailing script that is used to send newsletters from a clients website. I've used the same code before to produce another newsletter system and it has worked well and been used to send emails to various addresses, however our latest client has email addresses ending .eu and this seems to cause a problem. When the newsletter is sent from the site to the various subscribers, including gmail, hotmail, yahoo and our own company emails, the emails are received correctly by all but the clients email addresses, the ones ending in .eu. As there is nothing different between their mailing system and our own, which is run from the same hosting company, I have to conclude that it is something to do with the domain name. The emails are being sent to the addresses from the system, as I have a log file storing the email addresses when the mail out function is called, but the newsletter never appears in the inbox. I have created a new email account for the domain and that too isn't receiving the emails. It's not going into a spam folder as the webmail system marks spam by adding SPAM into the subject. I've tried to log if there are any errors using the following foreach($subscribers as $recipient) { $send_newsletter = $mail->send($recipient, $headers, $body); // LOG INFO $message = $recipient; if($send_newsletter) { $message .= ' SENT'; } elseif(PEAR::isError($send_newsletter)) { $message .= ' ERROR: '.$send_newsletter->getMessage(); } $message .= ' | '; fwrite($log_file,$message); } However this simple returns SENT for all recipients, so in theory there isn't anything wrong with the mailing function. I don't know a great deal about PEAR or the mailing function so I may be missing something important, but I'd have thought seeing the last thing to happen is sending the email out, and that seems to work, then it should reach the clients inbox. Is this something to do with the PEAR mailing function not liking .eu addresses or is it more likely to be something wrong in my code or with their domain? Any help is greatly appreciated as the client and myself are getting both confused and frustrated by the whole thing. Cheers

  • Get reference to all instances of jquery ui widget?

    - by Hailwood
    I am writing a jquery UI widget that simply wraps the bootstrap popover plugin, In the widget you can pass in the option 'singular', if this is passed in then it should call a function of all other instances of the plugin. something like $('#one').myWidget(); $('#two').myWidget(); $('#three').myWidget(); $('#four').myWidget(); $('#one').myWidget('show'); //stuff from widget one is now visible $('#two').myWidget('show'); //stuff from widget one and two are now visible $('#three').myWidget('show'); //stuff from widget one, two and three are now visible $('#two').myWidget('hide'); //stuff from widget one and three are now visible $('#four').myWidget('show', {singular:true}); //stuff from widget four is now visible So, I imagine the show function looking like: show: function(options){ options = options || {}; if(options.singular){ var instances = '????'; // how do I get all instances? $.each(instances, function(i, o){ o.myWidget('hide'); }); } this.element.popover('show'); } So, question being, how would I get a reference to all elements that have the myWidget widget on them?

  • jQuery $.getJSON - How do I parse a flickr.photos.search REST API call?

    - by Chad
    Trying to adapt the $.getJSON Flickr example: $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?", function(data){ $.each(data.items, function(i,item){ $("<img/>").attr("src", item.media.m).appendTo("#images"); if ( i == 3 ) return false; }); }); to read from the flickr.photos.search REST API method, but the JSON response is different for this call. Click here to see the JSON response. This is what I've done so far: var url = "http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=9322c53dde3b36bda33f79c16bb99104&tags=yokota+air+base&safe_search=1&per_page=20"; var src; $.getJSON(url + "&format=json&jsoncallback=?", function(data){ $.each(data.photos, function(i,item){ src = "http://farm"+ item.photo.farm +".static.flickr.com/"+ item.photo.server +"/"+ item.photo.id +"_"+ item.photo.secret +"_m.jpg"; $("<img/>").attr("src", src).appendTo("#images"); if ( i == 3 ) return false; }); }); I guess I'm not building the image src correctly.

This is the javascript <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script type="text/javascript" src="/js/jquery.hoverIntent.min.js"></script> <script type="text/javascript"> $(document).ready(function () { function megaHoverOver() { $(this).find(".menu_content").stop().fadeTo('fast', 1).show(); } function megaHoverOut() { $(this).find(".menu_content").stop().fadeTo('fast', 0, function () { $(this).hide(); }); } var config = { sensitivity: 2, interval: 50, over: megaHoverOver, timeout: 300, out: megaHoverOut }; $("#menu ul li").not(".parenttocurrent").not(".current").find(".menu_content").css({ 'opacity': '0' }); $("#menu ul li").not(".parenttocurrent").not(".current").hoverIntent(config); }); </script>

  • Is there a way to implement Caliburn-like co-routines in VB.NET since there's no yield keyword

    - by Miroslav Popovic
    Note that I'm aware of other yield in vb.net questions here on SO. I'm playing around with Caliburn lately. Bunch of great stuff there, including co-routines implementation. Most of the work I'm doing is C# based, but now I'm also creating an architecture guideline for a VB.NET only shop, based on Rob's small MVVM framework. Everything looks very well except using co-routines from VB. Since VB 10 is used, we can try something like Bill McCarthy's suggestion: Public Function Lines(ByVal rdr as TextReader) As IEnumerable(Of String) Return New GenericIterator(Of String) (Function(ByRef nextItem As String) As Boolean nextItem = rdr.ReadLine Return nextItem IsNot Nothing End Function) End Function I'm just failing to comprehend how a little more complex co-routine method like the one below (taken from Rob's GameLibrary) could be written in VB: public IEnumerable<IResult> ExecuteSearch() { var search = new SearchGames { SearchText = SearchText }.AsResult(); yield return Show.Busy(); yield return search; var resultCount = search.Response.Count(); if (resultCount == 0) SearchResults = _noResults.WithTitle(SearchText); else if (resultCount == 1 && search.Response.First().Title == SearchText) { var getGame = new GetGame { Id = search.Response.First().Id }.AsResult(); yield return getGame; yield return Show.Screen<ExploreGameViewModel>() .Configured(x => x.WithGame(getGame.Response)); } else SearchResults = _results.With(search.Response); yield return Show.NotBusy(); } Any idea how to achieve that, or any thoughts on using Caliburn co-routines in VB?

  • How do you parse the XDG/gnome/kde menu/desktop item structure in c++??

    - by Joe Soul-bringer
    I would like to parse the menu structure for Gnome Panels (the standard Gnome Desktop application launcher) and it's KDE equivalent using c/c++ function calls. That is, I'd like a list of what the base menu categories and submenu are installed in a given machine. I would like to do with using fairly simple c/c++ function calls (with NO shelling out please). I understand that these menus are in the standard xdg format. I understand that this menu structure is stored in xml files such as: /home/user/.config/menus/applications.menu I've look here: http://www.freedesktop.org/wiki/Specifications/menu-spec?action=show&redirect=Standards%2Fmenu-spec but all they offer is the standard and some shell files to insert item entries (I don't want shell scripts, I don't want installation, I definitely don't want to create a c-library from the XDG specification. I want to find the existing menu structure). I've looked here: http://library.gnome.org/admin/system-admin-guide/stable/menustructure-13.html.en for more notes on these structures. None of this gives me a good idea of how determine the menu structures using a c/c++ program. The actual gnome menu structures seem to be a horrifically hairy things - they don't seem to show the menu structure but to give an XML-coded description of all the changes that the menus have gone through since installation. I assume gnome panels parses these file so there's a function buried somewhere to do this but I've yet to find where that function is after scanning library.gnome.org for a couple of days. I've scanned the Nautilus source code as well but Panels seem to exist elsewhere or are burried well. Thanks in advance
