  • Creating a table with an initial element selected

    - by Tony
    I want to create a table which displays in each row a set of data, in addition to a radio button for possible selection. This can be achieved easily by using a simple table model class which extends the DefaultTableModel and a cell renderer and editor class which implements the TableCellRenderer and TableCellEditor interfaces respectively. What I really couldn't manage to do is to make the table to display initially one of the elements (rows) initially selected. It seems straightforward but it isn't...does anybody have a clue about it?

  • When does validation happen in Core Data?

    - by dontWatchMyProfile
    From the docs: If you make changes to managed objects associated with a given context, those changes remain local to that context until you commit the changes by sending the context a save: message. At that point—provided that there are no validation errors—the changes are committed to the store. So does that essentially mean, that validation happens automatically as soon as I call -save?

  • XQuery: Inserting Nodes

    - by CoolGravatar
    I'm reading in an XML file using XQuery and want to insert several nodes/elements and generate a new XML file. How can I accomplish this? I've tried using the replace() function, but, it looks like all my XML tags are being stripped when I call doc() to load my document. So calling replace() isn't any good if my XML tags are being removed. Any help? Are there other technologies I can use?

  • Use OpenOffice to do server-side ppt(x) to swf conversion

    - by Steven Xu
    I'd like to turn Powerpoint presentations to SWF files the same way that OpenOffice does it, except automatically through a command line call. I came across http://stackoverflow.com/questions/886144, which led me to explore PyUNO bridge, which comes with OpenOffice as well as the OpenOffice command line API, but I wasn't able to make anything productive of it. Any guidance is appreciated. If there is a good solution outside of OpenOffice, I would be happy to try it too.

  • How is thread local storage (__thread) implemented on LInux?

    - by anon
    __thread Foo foo; How is "foo" actually resolved? Does the compiler silently replace every instance of "foo" with a function call? Is "foo" stored somewhere relative to the bottom of the stack, and the compiler stores this as "hey, for each thread, have this space near the bottom of the stack, and foo is stored as "offset x from bottom of stack"" ? Insights please.

  • Accessing inbound HTTP headers in meteor?

    - by Alex K
    I'm working on an application that relies on data that the browser sends within the HTTP headers (and there's no way around this). This also happens to be my first time working with something node.js based, so it's very likely I'm completely missing something simple! Basically what I want to be able to do is call a method on the server from the client, and in that method read the HTTP headers that the client sent.

  • Using jQuery's ajax get request with parameters, returning page content

    - by Stevie Jenowski
    Thank you for looking at my question, as I appreciate your time. Okay, so I'm trying to use jQuery's get function to call my php script which ultimately returns a variable which is a built template of the main content of my page minus my static header/footer, for which I would like to replace the "old" page content without the page reloading. Can anyone point me in the right direction as to where I'm going wrong here? My code is as follows... jQuery: function getData(time, type) { $.ajax({ type: "GET", url: "getData.php", data: "time=" + time + "&type=" + type, success: function(data){ $('#pageContent').fadeOut("slow"); $('#pageContent').html(data); $('#pageContent').fadeIn("slow"); } }); return false; } getData.php(paraphrased): .... $time = empty($_GET['time']) ? '' : $_GET['time']; $type = empty($_GET['type']) ? '' : $_GET['type']; echo getData($time, $type); function getData($time, $type) ...... ..... $tmpl = new Template(); $tmpl->time= $time; $tmpl->type = $type; $builtpage = $tmpl->build('index.tmpl'); return $builtpage; ..... ...... jQuery function call: <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Orange")">Orange</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Apple")">Apple</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Banana")">Banana</a> When I click any link, the ajax seems to run fine, and the page does refuse to reload, but the content still remains unchanged... Anyone happen to know what's up?

  • php class extend - run something before running parent function

    - by Patrick
    Hi, say I have this class: class animal { function noise() { print 'woof'; } function move() { print 'moved'; } } class dog extends animal { } What I would like to do is when i run $dog-noise() or $dog-move(), it would run something first prior to calling animal class's noise/move. Is this doable? Like maybe logging the function call. If not with class extend, what else can I use to achieve this? Thank you!

  • Calling pthread_cond_signal without locking mutex

    - by Maysam
    Hi, I read somewhere that we should lock the mutex before calling pthread_cond_signal and unlock the mutext after calling it: The pthread_cond_signal() routine is used to signal (or wake up) another thread which is waiting on the condition variable. It should be called after mutex is locked, and must unlock mutex in order for pthread_cond_wait() routine to complete. My question is: isn't it OK to call pthread_cond_signal or pthread_cond_broadcast methods without locking the mutex?
