    - by Gaurav Saini
    Here is the piece of code that I have used for Java 5.0 TreeSet<Integer> treeSetObj = new TreeSet<Integer>( Collections.reverseOrder() ) ; Collections.reverseOrder() is used to obtain a comparator in order to reverse the way the elements are stored and iterated. Is there a more optimized way of doing it?

  • How to get jQuery draggable elements scroll with mb.imageNavigator

    - by bulltorious
    I am using jQuery mb.imageNavigator (1.8) from http://pupunzi.open-lab.com/mb-jquery-components/mb-imagenavigator/ to implements a Risk type game adjucation system. Using the imageNavigator plugin I am able to scroll around a large game map of the world. My issue is when I declare some elements as draggable and drag them onto the map image, their location does not stay relative to where in the picture I put them. They just stay fixed on the screen no matter where I scroll. Does anyone know how to make the the draggable elements scroll with the image? Matteo posts about "you can add an additional content layer that overlay image and moves with it" and posts an example, but I can't make it work. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> ` <head> <script type="text/jscript" src="lib/jquery/jquery-1.3.2.js"> </script> <script type="text/jscript" src="lib/jquery/jquery-ui-1.7.2.custom.min.js"> </script> <script type="text/jscript" src="lib/utilities/mbImgNav.min.js_0.js"> </script> <script type="text/jscript" src="lib/utilities/start.js"> </script> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> </head> <body> <div id="AdamsAshTray" style="float:right; background-color:red; z-index:999"> test test test </div> <div id="navArea"> <div imageUrl="someimage" navPosition="BR" navWidth="100" style="display:none;" class="imagesContainer"> <span class="title">zuccheriera</span> <div class="description"> <STRONG>description1</STRONG> </div> </div> </div> </body> $(document).ready(function(){ $("#navArea").imageNavigator({ areaWidth:1820, areaHeight:1000, draggerStyle: "1px dotted red", navOpacity: .8 }) $("#AdamsAshTray").draggable({ grid: [20,20] }); })`

  • Sharing elements between Android apps, a question of best practices

    - by Emanuil
    Here's a quote from Android's Dev Guide: A central feature of Android is that one application can make use of elements of other applications (provided those applications permit it). For example, if your application needs to display a scrolling list of images and another application has developed a suitable scroller and made it available to others, you can call upon that scroller to do the work, rather than develop your own. Isn't it a bad practice to make an app dependent on other apps?

  • DOM Elements with same id and jQuery

    - by Steve
    Hi I have multiple elements with the same structure in my application. Second div element's id varies as per the comment id in the db which is unique. There are elements with the id 'vote_up' and 'vote_down'. This gets repeated for each comment.What happens is that, as I mentioned, there are multiple comments. I want to perform an Ajax request. First of this structure functions properly using ajax, but the rest does an http request. Btw I am developing a rails application and I am using jQuery. <div id="post_comment"> john<i> says </i> Comment<br/> <div id="comment_10_div"> **<form action="/comments/vote_up" id="vote_up" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[post_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote up" /> </form> <label id="comment_10">10</label> **<form action="/comments/vote_down" id="vote_down" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[place_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote Down" /> </form> </div> Can you please help me to solve this Thanks

    I used myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS)); to order panels vertically (one under another one). But myPanel defined in the shown way change the included panel. In more details, it tries to set the same hight and width for the included panels. Can it be changed? Can BoxLayout adopt size of the included elements?

  • referencing DOM elements in jQuery

    - by Lyon
    Hi, I would select multiple DOM elements using a typical code such as this: $('#ele1, #ele2, #ele3').click(function () {}); If I have variables of each DOM element, e.g. var domEle1 = $('#ele1'); var domEle2 = $('#ele2'); var domEle3 = $('#ele3'); How can I select them all at once? Instead of individually... domEle1.click(function () {}); Thanks!

  • Extracting Certain XML Elements with PHP SimpleXML

    - by Peter
    I am having some problems parsing this piece of XML using SimpleXML. There is always only one Series element, and a variable number of Episode elements beneath. I want to parse XML so I can store the Series data in one table, and all the Episode data in another table. XML: <Data> <Series> <id>80348</id> <Genre>|Action and Adventure|Comedy|Drama|</Genre> <IMDB_ID>tt0934814</IMDB_ID> <SeriesID>68724</SeriesID> <SeriesName>Chuck</SeriesName> <banner>graphical/80348-g.jpg</banner> </Series> <Episode> <id>935481</id> <Director>Robert Duncan McNeill</Director> <EpisodeName>Chuck Versus the Third Dimension 2D</EpisodeName> <EpisodeNumber>1</EpisodeNumber> <seasonid>27984</seasonid> <seriesid>80348</seriesid> </Episode> <Episode> <id>935483</id> <Director>Robert Duncan McNeill</Director> <EpisodeName>Buy More #15: Employee Health</EpisodeName> <EpisodeNumber>2</EpisodeNumber> <seasonid>27984</seasonid> <seriesid>80348</seriesid> </Episode> </Data> When I attempt to access just the first Series element and child nodes, or iterate through the Episode elements only it does not work. I have also tried to use DOMDocument with SimpleXML, but could not get that to work at all. PHP Code: <?php if(file_exists('en.xml')) { $data = simplexml_load_file('en.xml'); foreach($data as $series) { echo 'id: <br />' . $series->id; echo 'imdb: <br />' . $series->IMDB_ID; } } ?> Output: id:80348 imdb:tt0934814 id:935481 imdb: id:1534641 imdb: Any help would be greatly appreciated.

  • Number of different elements in an array.

    - by AB
    Is it possible to compute the number of different elements in an array in linear time and constant space? Let us say it's an array of long integers, and you can not allocate an array of length sizeof(long). P.S. Not homework, just curious. I've got a book that sort of implies that it is possible.

  • Saving elements to database with $.ajax()

    - by Justin Meltzer
    I'm trying to save dynamically created elements in my application.js file to the database. Would the code look something like this?: $.ajax({ type: "POST", data: { title: 'oembed.title', thumbnail_url: 'oembed.thumbnail_url'} }); Is there anything I'm missing? Assume that oembed.title and oembed.thubnail_url hold the values I want to save, and that title and thumbnail are the database columns.
