  • proper way to hide dynamic elements with jQuery

    - by GrandVizier
    I have a div element which my code will fill with a dynamic amount of links. Using jquery, I want to hide all the links except the first one. This is what I came up with and it works, I was just wondering if this is the best way to do it: $("#panelContainer").each(function(n) { $(this).children().hide(); $("#panelContainer a:first").show(); });

  • c++ property class structure

    - by Without me Its just Aweso
    I have a c++ project being developed in QT. The problem I'm running in to is I am wanting to have a single base class that all my property classes inherit from so that I can store them all together. Right now I have: class AbstractProperty { public: AbstractProperty(QString propertyName); virtual QString toString() const = 0; virtual QString getName() = 0; virtual void fromString(QString str) = 0; virtual int toInteger() = 0; virtual bool operator==(const AbstractProperty &rightHand) = 0; virtual bool operator!=(const AbstractProperty &rightHand) = 0; virtual bool operator<(const AbstractProperty &rightHand) = 0; virtual bool operator>(const AbstractProperty &rightHand) = 0; virtual bool operator>=(const AbstractProperty &rightHand) = 0; virtual bool operator<=(const AbstractProperty &rightHand) = 0; protected: QString name; }; then I am implementing classes such as PropertyFloat and PropertyString and providing implementation for the comparator operators based on the assumption that only strings are being compared with strings and so on. However the problem with this is there would be no compiletime error thrown if i did if(propertyfloat a < propertystring b) however my implementation of the operators for each derived class relies on them both being the same derived class. So my problem is I cant figure out how to implement a property structure so that I can have them all inherit from some base type but code like what I have above would throw a compile time error. Any ideas on how this can be done? For those familiar with QT I tried using also a implementation with QVariant however QVariant doesn't have operators < and defined in itself only in some of its derived classes so it didn't work out. What my end goal is, is to be able to generically refer to properties. I have an element class that holds a hashmap of properties with string 'name' as key and the AbstractProperty as value. I want to be able to generically operate on the properties. i.e. if I want to get the max and min values of a property given its string name I have methods that are completely generic that will pull out the associated AbstactProperty from each element and find the max/min no matter what the type is. so properties although initially declared as PropertyFloat/PropertyString they will be held generically.

  • jQuery javascript dynamic menus with mbMenu plugin

    - by lafoaug
    Im using the MbMenu jQuery plugin. http://plugins.jquery.com/project/mbMenu http://pupunzi.open-lab.com/2009/01/18/mbmenu/ I am probably being ridiculously stupid but I wish to have multiple menus on the same page, but not load them from external files (the html structure of the menu already exists on the page). To me the only place you define what menu is linked to the element you call buildMenu on is the 'template' construction which is a external file. Thanks.

  • Twitter api and retweets

    - by Juan Manuel
    I'm trying to get the last tweet from the people I follow using the twitter api (http://api.twitter.com/1/statuses/friends.json&screen_name=[username]), but I noticed that if the user's last tweet is a retweet, the json data does not contain a "status" element. Using the "user timeline" api does not work either, the last tweet is the last non retweeted tweet. Is there a way to get the real last status, even if it's a RT, through the twitter API?

  • Fix elements within objects at their position? (Prevent movement when resizing)

    - by Skadier
    I would like to know if it is possible to fix elements at their absolute position within custom elements in InDesign CS5? I created a kind of speech bubble and I would like to place a stripline within this bubble to separate two content areas. Just a little scheme to show the desired layout as Pseudo-Markup :D <speech-bubble> <textbox>HEADER SECTION</textbox> <stripline> <textbox>Some other text</textbox> </speech-bubble> I created something like this but with two separate elements which aren't connected. So I have to select both of them in order to move the whole bubble. Then I tried to connect them using Object->Paths->Create linked path but then the stripline moves and the HEADER SECTION moves too. All in all I would like to have a speech bubble which can be resized in order to hold more text but it shouldn't make the HEADER_SECTION larger or move the stripline. Hope you understand what I mean :D Thanks in advance!

  • Css For Gridview paging

    - by arunendra
    Hi My question is, can I control the style of the paging element separately of top and bottom, I have set the paging to appear in both top and bottom of the gridview, and I want to see that the top pagination is little high up in the page, to do that I used the cssClass and set margin-top:20px and made the position: absolute, this does change the position of the top paging area and set it rightly for me, but the bottom pagination has also come up as a result and now sits inside the grid data!! Is there any way to solve this? Thanks and regards Arunendra

  • JQuery UI: is it possible to know where an object has been dropped?

    - by Jack Duluoz
    Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

  • Ignoring namespace prefix while parsing xml

    - by Rachel
    If a xhtml file has namespace prefixes in the document and the namespace for the prefixes is not defined, is it possible to ignore the prefixes and still parse the file when using SAX parser. Is there a way to get rid of the error "The prefix for element is not bound." without defining the namespace for the prefixes while parsing?

  • Another void C# question

    - by Jim Jones
    Have a type in the header files I'm working with called VTVOID it is the type of a struct element and a number of parameters. In the header file defining types is the line #define VTVOID void I read in another discussion the void maps to System.Void however when I plug that into the C# code I get the error "System.Void cannot be used in C# -- use typeof(void) to get the void object." So what type do I plug in? Jim

  • Evaluate column value into rows

    - by Hugo Palma
    I have a column whose value is a json array. For example: [{"att1": "1", "att2": "2"}, {"att1": "3", "att2": "4"}, {"att1": "5", "att2": "6"}] What i would like is to provide a view where each element of the json array is transformed into a row and the attributes of each json object into columns. Keep in mind that the json array doesn't have a fixed size. Any ideas on how i can achieve this ?

  • postgres subquery w/ derived column

    - by Wells
    The following query won't work, but it should be clear what I'm trying to do: split the value of 't' on space and use the last element in that array in the subquery (as it will match tl). Any ideas how to do this? Thanks! SELECT t, y, "type", regexp_split_to_array(t, ' ') as t_array, sum(dr), ( select uz from f.tfa where tl = t_array[-1] ) as uz, sc FROM padres.yd_fld WHERE y = 2010 AND pos <> 0 GROUP BY t, y, "type", sc;

  • Generate sample XML from composite hierarchical structure

    - by Jevgenij Nekrasov
    Let's say I have composite hierarchical structure. Each object in the structure has child collection of the same objects. Each object has XPath property, which stores the exact xpath to the element inside XML file. Right now I am trying to create an extension, which can generate XML string from that hierarchical structure, but first I want to make some sort of research what is the most efficient way to do that? ant what is the easiest way?

  • How to set clickable and highlightable a View?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • Simple prolog program. Getting error: >/2: Arguments are not sufficiently instantiated

    - by user1279812
    I made a prolog program posAt(List1,P,List2) that tests whether the element at position P of List1 and List2 are equal: posAt([X|Z],1,[Y|W]) :- X=Y. posAt([Z|X],K,[W|Y]) :- K1, Kr is K - 1, posAt(X,Kr,Y). When testing: ?- posAt([1,2,3],X,[a,2,b]). I expected an output of X=2 but instead I got the following error: ERROR: /2: Arguments are not sufficiently instantiated Why am I getting this error?
