What is happening though is that when I move onto the language list, and I go past Germany (~50% down the list?), the hover() loses focus and closes the original menu, which closes the language menu. Any idea's what is causing the issue? Any ideas how to fix the issue? I have tried the hoverIntent() plugin as well to no avail.

  • Coding a Tumblr Theme - List posts as list or just a stack of divs?

    - by Trippy
    I'm in the process of coding my own Tumblr Theme. Well I was wondering how should I list the posts? In the basic theme, (the one you get when you sign up) doesn't use list items (<li>). But I saw in another theme that it does use list items. By the way, this is what I mean... <div class="post-text"><div> <div class="post-audio"><div> ... or <ul> <li class="post-text"></li> ... </ul> I'm confused on the way I should go - I want to go to the semantic way of doing it because the theme will be built in HTML5.

  • Apply Alloy UI 1.5 datepicker to multiple instances

    - by MyTitle
    I want to create Alloy UI datapickers on multiple form fields: <div id="date_1_wrapper"> <input type="text" class="datepick" id="date_1" /> </div> <div id="date_2_wrapper"> <input type="text" class="datepick" id="date_2" /> </div> Using JQuery I can do it using following code: $('.datepick').each(function(){ $(this).datepicker(); }); But how to achieve same functionality in Alloy UI? For now I use following code, but this code apply DatePickers by ID, not by CSS class in loop: AUI().use( 'aui-datepicker', function(A) { new A.DatePicker ( { calendar: { dateFormat: '%d/%m/%Y' }, trigger: '#date_1' } ).render('#date_1_wrapper'); new A.DatePicker( { calendar: { dateFormat: '%d/%m/% }, trigger: '#date_2' } ).render('#date_2_wrapper'); } ); I think it this code can be used in beginning, but how to deal with input's and div's ID's? (A.all('.datepcik').each(function() {)

  • C++0x rvalue references - lvalues-rvalue binding

    - by Doug
    This is a follow-on question to http://stackoverflow.com/questions/2748866/c0x-rvalue-references-and-temporaries In the previous question, I asked how this code should work: void f(const std::string &); //less efficient void f(std::string &&); //more efficient void g(const char * arg) { f(arg); } It seems that the move overload should probably be called because of the implicit temporary, and this happens in GCC but not MSVC (or the EDG front-end used in MSVC's Intellisense). What about this code? void f(std::string &&); //NB: No const string & overload supplied void g1(const char * arg) { f(arg); } void g2(const std::string & arg) { f(arg); } It seems that, based on the answers to my previous question that function g1 is legal (and is accepted by GCC 4.3-4.5, but not by MSVC). However, GCC and MSVC both reject g2 because of clause 13.3.3.1.4/3, which prohibits lvalues from binding to rvalue ref arguments. I understand the rationale behind this - it is explained in N2831 "Fixing a safety problem with rvalue references". I also think that GCC is probably implementing this clause as intended by the authors of that paper, because the original patch to GCC was written by one of the authors (Doug Gregor). However, I don't this is quite intuitive. To me, (a) a const string & is conceptually closer to a string && than a const char *, and (b) the compiler could create a temporary string in g2, as if it were written like this: void g2(const std::string & arg) { f(std::string(arg)); } Indeed, sometimes the copy constructor is considered to be an implicit conversion operator. Syntactically, this is suggested by the form of a copy constructor, and the standard even mentions this specifically in clause 13.3.3.1.2/4, where the copy constructor for derived-base conversions is given a higher conversion rank than other implicit conversions: A conversion of an expression of class type to the same class type is given Exact Match rank, and a conversion of an expression of class type to a base class of that type is given Conversion rank, in spite of the fact that a copy/move constructor (i.e., a user-defined conversion function) is called for those cases. (I assume this is used when passing a derived class to a function like void h(Base), which takes a base class by value.) Motivation My motivation for asking this is something like the question asked in http://stackoverflow.com/questions/2696156/how-to-reduce-redundant-code-when-adding-new-c0x-rvalue-reference-operator-over ("How to reduce redundant code when adding new c++0x rvalue reference operator overloads"). If you have a function that accepts a number of potentially-moveable arguments, and would move them if it can (e.g. a factory function/constructor: Object create_object(string, vector<string>, string) or the like), and want to move or copy each argument as appropriate, you quickly start writing a lot of code. If the argument types are movable, then one could just write one version that accepts the arguments by value, as above. But if the arguments are (legacy) non-movable-but-swappable classes a la C++03, and you can't change them, then writing rvalue reference overloads is more efficient. So if lvalues did bind to rvalues via an implicit copy, then you could write just one overload like create_object(legacy_string &&, legacy_vector<legacy_string> &&, legacy_string &&) and it would more or less work like providing all the combinations of rvalue/lvalue reference overloads - actual arguments that were lvalues would get copied and then bound to the arguments, actual arguments that were rvalues would get directly bound. Questions My questions are then: Is this a valid interpretation of the standard? It seems that it's not the conventional or intended one, at any rate. Does it make intuitive sense? Is there a problem with this idea that I"m not seeing? It seems like you could get copies being quietly created when that's not exactly expected, but that's the status quo in places in C++03 anyway. Also, it would make some overloads viable when they're currently not, but I don't see it being a problem in practice. Is this a significant enough improvement that it would be worth making e.g. an experimental patch for GCC?

  • Python: Getting the attribute name that the created object will be given

    - by cool-RR
    Before I ask this, do note: I want this for debugging purposes. I know that this is going to be some bad black magic, but I want to use it just during debugging so I could identify my objects more easily. It's like this. I have some object from class A that creates a few B instances as attributes: class A(object): def __init__(self) self.vanilla_b = B() self.chocolate_b = B() class B(object): def __init__(self): # ... What I want is that in B.__init__, it will figure out the "vanilla_b" or whatever attribute name it was given, and then put that as the .name attribute to this specific B. Then in debugging when I see some B object floating around, I could know which one it is. Is there any way to do this?

  • Populate properties decorated with an attribute

    - by PUT
    Are there any frameworks that assist me with this: (thinking that perhaps StructureMap can help me) Whenever I create a new instance of "MyClass" or any other class that inherits from IMyInterface I want all properties decorated with [MyPropertyAttribute] to be populated with values from a database or some other data storage using the property Name in the attribute. public class MyClass : IMyInterface { [MyPropertyAttribute("foo")] public string Foo { get; set; } } [AttributeUsage(AttributeTargets.Property)] public sealed class MyPropertyAttribute : System.Attribute { public string Name { get; private set; } public MyPropertyAttribute(string name) { Name = name; } }

  • "partial views" best practices for 'container' divs?

    - by ropstah
    What is the 'best' way to handle the html markup for partial views? (which are also refreshed using AJAX) The biggest issue I run into is where to place the 'container' div... Consider having a masterpage and a partial view. (class="" could be interchanged with id="" depending if the partial is guaranteed to be unique, however this isn't really important to the issue i think) Masterpage: <div id="place1" class="placeholder"> <!-- render partial --> </div> Partial: <div id="partial1" class="partial"> <!-- content --> </div> I feel that something isn't being done right. However I cannot remove the div in the masterpage, because I need that to 'encapsulate' the response from AJAX partial updates. And also I cannot move the div in the partial to the masterpage, because that would require to move 'partial' info to the masterpage... How do you handle this?

  • When to use the Flyweight Pattern

    - by elmt
    So I've just gotten on the boost train and was checking out the flyweight pattern and was interested in implementing it in my project. Obviously, it doesn't make sense to use it on any class that has only has one instance of it. However, say I have 5 instances of an class. Should I be using the flyweight pattern or should it be only used for a class that has at least N instances. I realize that many factors will influence this answer (how many fields there are, the size of the fields, etc.).

  • Sending an array of complex objects in the get string in C# ASP.NET MVC

    - by Mr Snuffle
    Hi, I want to send an array of objects in the get request string. I know this isn't the optimal solution, but I really just want to get this up and running. If I have a class, something like this public class Data { public int a { get; set; } public int b { get; set; } } public class RequestViewData { public IList<Data> MyData { get; set; } } I thought I could bind the MVC route to a web request like this http://localhost:8080/Request?MyData[0].a=1&MyData[0].b=2&MyData[1].a=3&[MyData[1].b=4 But all this does is create an array of two data objects without populating the values 1,2, 3 or 4. Is there a way to bind complex objects arrays?

  • Eclipse doesn't see my new junit test

    - by morgancodes
    I'm using eclipse to run the tests in a single junit(4) test class. The tests in the class all run just fine. Then I add an additional test and run the class through the test running in ecplise again. Only the old tests are run. The new test isn't seen by eclipse. There's no error or anything, it's just as if eclipse is looking at an old version of the test. If I run the tests using maven, everything works fine. Additionally, after I run the tests in maven, ecplipse can see and run the new test correctly. Any ideas what's going on? Any ideas how to get ecplipse's test runner to see my new test cases?

  • Django: Geocoding an address on form submission?

    - by User
    Trying to wrap my head around django forms and the django way of doing things. I want to create a basic web form that allows a user to input an address and have that address geocoded and saved to a database. I created a Location model: class Location(models.Model): address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) postal_code = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100) latitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) longitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) And defined a form: class LocationForm(forms.ModelForm): class Meta: model = models.Location exclude = ('latitude','longitude') In my view I'm using form.save() to save the form. This works and saves an address to the database. I created a module to geocode an address. I'm not sure what the django way of doing things is, but I guess in my view, before I save the form, I need to geocode the address and set the lat and long. How do I set the latitude and longitude before saving?

  • HQL join after output of subquery

    - by user350374
    Hey, Say I have 3 classes class foo1 { List prop1;} class foo2 { foo3 prop2;} class foo3{ int Id;} now I want to select distinct foo2's from foo1 and get Id of foo3. I need to write a HQL stmt for the same. I tried the following select c.Id from (select distinct(a.prop1) from foo1.prop1 as a ) as b inner join b.prop2 as c This throws an 'Antlr.Runtime.NoViableAltException How do you suggest I should go about the same. Please note the inner subquery is working fine. So if I have made some mistakes in there please ignore that. I need a method to do the latter. Thanks in Advance.

  • Android: Using MediaRecorder to crop an existing audio file?

    - by user141146
    Hi, I'd like to take an existing mp3 file located on an SD card and arbitrarily crop it (e.g. crop from 0:12 to 1:14 in a 3 minute song). The only class that I've seen that seems remotely relevant to do this is the MediaRecorder class. My 'hope' would be to "record" an existing file like this: MediaRecorder recorder = new MediaRecorder(); recorder.setAudioSource(###some magical way of specifying an existing file??###); But this obviously doesn't work (setAudioSource() takes an int and seems to default to the phone's microphone). Is there a class or an approach that can be used to crop audio on the phone itself? TKS!!

  • Uses for static generic classes?

    What are the key uses of a Static Generic Class in C#? When should they be used?

  • How to declare a generic constraint that is a generic type

    - by HackedByChinese
    I have a two generic abstract types: Entity and Association. Let's say Entity looks like this: public class Entity<TId> { //... } and Association looks like this: public class Association<TEntity, TEntity2> { //... } How do I constrain Association so they can be of any Entity? I can accomplish it by the following: public class Association<TEntity, TId, TEntity2, TId2> where TEntity : Entity<TId> where TEntity2: Entity<TId2> { //... } This gets very tedious as more types derive from Association, because I have to keep passing down TId and TId2. Is there a simpler way to do this, besides just removing the constraint?

  • Anyone using ASP.NET MembershipProvider with Nhibernate?

    - by JLago
    Hi, I'm trying to implement Membership controls in a mvc 2 application and i'm having trouble dealing with the MembershipUser class. I have my own data store (in Postgresql) and I'm using Nhibernate to deal with it from C#. The thing is, I have my own user class, but I can't use it with any provider I found that implements Membership, because all the functions return the predefined MembershipUser class and cannot return my own. I'm losing my mind here, is there any way i can work with this, or should I implement everything myself? thanks in advance!

  • Java generics: Illegal forward reference

    - by Arian
    Given a generic interface interface Foo<A, B> { } I want to write an implementation that requires A to be a subclass of B. So I want to do class Bar<A, B super A> implements Foo<A, B> { } // --> Syntax error or class Bar<A extends B, B> implements Foo<A, B> { } // --> illegal forward reference But the only solution that seems to work is this: class Bar<B, A extends B> implements Foo<A, B> { } which is kind of ugly, because it reverses the order of the generic parameters. Are there any solutions or workarounds to this problem?

  • How can I create a collection of references in C#

    - by Jonathan Kaufman
    Ok I am having a cross language hiccup. In C# with it's great collections like List and I have: a Map class with properties of: List<byte[]> Images; List<Tile> Tiles; a Tile Class of: byte[] ImageData; int X; int Y; Now I want to add an image to the Map class and have the ImageData property of the Tile Classes to "reference" it. I have discovered I can't just assign it Images[0]. You can't have a reference to an object of a List. My fix was to create a Dictionary. Is this the best way or can I somehow have a "pointer" to a collection of objects?

  • Django 1.5 custom User model error. "Manager isn't available; User has been swapped"

    I extend the django user model as described in the dev doc. I wan't to keep most of the original User model features so I extend the AbstractUser class. I've defined in settings.py: AUTH_USER_MODEL = 'myapp.CustomUser' My user class: class CustomUser(AbstractUser): custom_field = models.ForeignKey('OtherModel') objects = UserManager() Everything seems to work fine but when I try to make it managed by the admin site: admin.site.register(CustomUser, UserAdmin) I get this error on the admin CustomUser creation page (after validation of the password confirmation form): AttributeError: Manager isn't available; User has been swapped for 'myapp.CustomUser' The point is that I need this model managed by the admin site in order to have the same creation process as with the original User model (two step process with password validation). Thanks for any reply

  • INotifyPropertyChange ~ PropertyChanged not firing when property is a collection and a new item is a

    - by eponymous23
    I have a class that implements the INotifyPropertyChanged interface. Some of the properties of the class are of type List. For example: public List<string> Answers { get { return _answers; } set { _answers = value; onPropertyChanged("Answers") } } ... private void onPropertyChanged(string propertyName) { if(this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } If I assign a new List<string> to Answer, then the PropertyChanged event fires as expected; but if I add a string string to the Answer list using the List Add method, then PropertyChanged event doesn't fire. I was considering adding an AddAnswer() method to my class, which would handle calling the lists's Add method and would call onPropertyChanged() from there, but is that the right way to do it? Is there a more elegant way of doing it? Cheers, KT

  • JavaScript socket vs. Flash socket?

    - by Dr.Dredel
    Steve Jobs just posted this article on why Apple rejects Flash... http://www.apple.com/hotnews/thoughts-on-flash/ I agree that javascript and css can be used to replicate some of Flash's animation, though Flash does all sorts of scaling and tweening that is incredibly powerful, and I'm not sure that there's anything comparable in javascript, if there is, I certainly haven't seen it. However, my question is about the socket. Flash has an incredibly powerful openSocket class that allows you to connect to a server and have the server and the client talk back and forth to one another. As far as I know there is no equivalent class in Javascript. Am I mistaken? Is there some secret mystery Ajax class that replicates the openSocket? If not, then that feature alone makes Flash an invaluable tool. I'm interested in all answers though... and yes this IS a programming question! :)
