  • QtScript: Passing an array of objects to C++

    - by Plow
    Hi, I want to pass an array of objects from my QtScript to C++ but I have not been able to figure out how to achieve this. As soon as I create an array, the elements inside it are converted to strings before I can access them. This is what I have been trying so far: class myObject : public QObject, public QScriptable { Q_OBJECT public Q_SLOTS: void test(QVariantList list); }; void myObject::test(QVariantList list) { for (QVariantList::const_iterator it = list.begin(); it != list.end(); ++it) { QVariant element = *it; qDebug() << "List element type: " << element.typeName(); if (element.canConvert<QVariantMap>()) { // Not getting here } } } The following script myObject.test([{"foo": 1, "bar": 2}, {"baaz": 3, "baaaz": 4}]); prints List element type: "QString" List element type: "QString" I am using Qt 4.6...

  • Passing an Ajax variable to a Codeigniter function

    - by Matt
    Hello, I think this is a simple one. I have a Codeigniter function which takes the inputs from a form and inserts them into a database. I want to Ajaxify the process. At the moment the first line of the function gets the id field from the form - I need to change this to get the id field from the Ajax post (which references a hidden field in the form containing the necessary value) instead. How do I do this please? My Codeigniter Controller function function add() { $product = $this->products_model->get($this->input->post('id')); $insert = array( 'id' => $this->input->post('id'), 'qty' => 1, 'price' => $product->price, 'size' => $product->size, 'name' => $product->name ); $this->cart->insert($insert); redirect('home'); } And the jQuery Ajax function $("#form").submit(function(){ var dataString = $("input#id") //alert (dataString);return false; $.ajax({ type: "POST", url: "/home/add", data: dataString, success: function() { } }); return false; }); As always, many thanks in advance.

  • Using free function as pseudo-constructors to exploit template parameter deduction

    - by Poita_
    Is it a common pattern/idiom to use free functions as pseudo-constructors to avoid having to explicitly specify template parameters? For example, everyone knows about std::make_pair, which uses its parameters to deduce the pair types: template <class A, class B> std::pair<A, B> make_pair(A a, B b) { return std::pair<A, B>(a, b); } // This allows you to call make_pair(1, 2), // instead of having to type pair<int, int>(1, 2) // as you can't get type deduction from the constructor. I find myself using this quite often, so I was just wondering if many other people use it, and if there is a name for this pattern?

  • Passing in **kwargs from Flex over PyAMF

    - by cookiecaper
    Anyone know if it is easily possible to send **kwargs over PyAMF from NetConnection.call()? I would like it. I could write a wrapper around the actual function and expose that and perform some parsing manually to determine the kwargs to pass in, but I don't want to do that. I will just use a normal argument list in that case.

  • Pass an Event as parameter

    - by dkson
    I have a class which bundles events and registers controls to easily register/unregister them, it's basically used this way: Private Sub MyFocusHandler(ByVal sender As Object, ...) ... End Sub ... Dim b1 = new MyTextBox() Dim b2 = new MyTextBox() .... 'Lot of Controls' Dim cr = new ControlRegistration() cr.RegisterControl(b1) cr.RegisterControl(b2) .... 'Register a lot of controls' cr.RegisterEvent("Focus",New EventHandler(AddressOf MyFocusHandler)) cr.RegisterEvent("Validate",New EventHandler(AddressOf MyValidateHandler)) So I don't have to add the handlers manually for each control. The ControlRegistration-Class will cycle through the list of registered controls and check if a control has a registered event and then attach the eventhandler, something like: ... For Each control in contols Dim ev_info As Reflection.EventInfo = _ control.GetType().GetEvent(.GetType().GetEvent(event_name)) If Not (ev_info Is Nothing) Then ev_info.AddEventHandler ... ... My problem is that i am identifying the event by a string Public Sub RegisterEvent(ByVal eventName As String, ByVal handler As [Delegate]) ... ... cr.RegisterEvent("Focus",New EventHandler(AddressOf MyFocusHandler)) I don't want to depend on the name of the event, since it is possibly that the name changes, and then things will break up. Is there a way I can do this like: Public Sub RegisterEvent(ByVal theEvent As ???, ByVal handler As [Delegate]) ... ... cr.RegisterEvent(IMyControl.MyEvent,New EventHandler(AddressOf MyEventHandler)) I hope it is clear what I want to archive. Anybody any ideas? Thanks

  • Passing variables to callback functions

    - by mickyjtwin
    I am trying to write a jQuery plugin, that can be applied to a selector. Within this plugin, there are multiple calls to webservices, where callback methods are required. The problem I am having is maintaining the current context item in the each loop of the selector. (function($){ $.fn.myMethod = function(){ return this.each(function(){ var c = $(this); $.api.methodToCall("", CallbackFunction); }); }; function CallbackFunction(data, result){ // do stuff based on c } })(jQuery); Normally, you would provide the callback function straight away, which allows me to access c, however within the callback function, there potentially is another api call, so it would start to get messy. Is there any way to do this?

  • Passing Info From One View to Another

    - by 01010011
    EDIT 1. The results of a query from my database are displayed on my view page. Next to each unique result is a button: // first_view.php <?php echo form_open('controller/method'); ?> <?php foreach($results_found as $item): ?> <p><?php echo $item->name ?></p> <p><?php form_submit('buy','Buy This'); ?></p> When a user clicks on one of these buttons (lets say button 4), I would like to display the user's choice from the array onto another view. I've tried using this: // first_view.php <?php echo $this->session->set_userdata('choice',$item); ?> immediately before // first_view.php <?php echo form_close(); ?> thinking that the user's final choice would be stored there so I can display it on another view like this: // second_controller.php $c = $this->session->userdata('choice'); // second_view.php echo 'Your Choose: '. $c; However, what actually displays is the last result displayed on first_view.php, not what the user choose. My question is, if the user clicked on button 4, how do I get that particular choice displayed onto another view? END OF EDIT1 ORIGINAL QUESTION My view page (CodeIgniter) displays the contents of an array in the form of several links. If a user clicks on a link, I want the user to be taken to another view page (via a controller) that gives more information concerning that particular link (which is stored in that particular position in the array) My question is, how do I access and display the contents of that particular location within the array on the second view file without getting a "Undefined variable error" on the second view? Here is what I am trying to do in code form // my_controller.php $array_name['variable_name']; $this->load->view('first_view.php'); // first_view.php <?php foreach($variable_name as $vn): ?> <?php echo anchor('controller_name' $vn->info ?> // if user clicks on 3rd link <?php endforeach ?> // I want to beable to access // index 2 of the array in the // second view file so I can // display more info // second_view.php <?php $vn[2]->info ?>

  • passing groups of properties from 1 class to another

    - by insanepaul
    I have a group of 13 properties in a class. I created a struct for these properties and passed it to another class. I need to add another 10 groups of these 13 properties. So thats 130 properties in total. What do I do? I could add all 130 properties to the struct. Will this affect performance and readability I could create a list of structs but don't know how to access an item eg. to add to the list: listRowItems.Add(new RowItems(){a=1, b=1, c=1, d=1...}); listRowItems.Add(new RowItems(){a=2, b=2, c=2, d=2...}); How do I access the second group item b? is it Could I use just a dictionary with 130 items Should I use a list of dictionaries (again I don't know how to access a particular item) Should I pass in a class of 130 properties Just for your interest the properties are css parameters used for a composite control. The control displays 13 elements in each row and there are 10 rows and each row is customisable.

  • Why does using Collections.emptySet() with generics work in assignment but not as a method parameter

    - by Karl von L
    So, I have a class with a constructor like this: public FilterList(Set<Integer> labels) { ... } and I want to construct a new FilterList object with an empty set. Following Joshua Bloch's advice in his book Effective Java, I don't want to create a new object for the empty set; I'll just use Collections.emptySet() instead: FilterList emptyList = new FilterList(Collections.emptySet()); This gives me an error, complaining that java.util.Set<java.lang.Object> is not a java.util.Set<java.lang.Integer>. OK, how about this: FilterList emptyList = new FilterList((Set<Integer>)Collections.emptySet()); This also gives me an error! Ok, how about this: Set<Integer> empty = Collections.emptySet(); FilterList emptyList = new FilterList(empty); Hey, it works! But why? After all, Java doesn't have type inference, which is why you get an unchecked conversion warning if you do Set<Integer> foo = new TreeSet() instead of Set<Integer> foo = new TreeSet<Integer>(). But Set<Integer> empty = Collections.emptySet(); works without even a warning. Why is that?

  • Trouble passing JSP values to ActionForm (Struts)

    - by tacotime
    Hi, I am a newbie to Struts and have inherited a problem. I am trying to pass 3 values contained in the same table cell from a JSP to my ActionForm class. The first value (and others in the JSP) work fine, but for some reason the other two do not. I have the appropriate getters and setters, but only the first (newrecnum) shows up, the other two are null. Is there a limitation to only pass the first value? Or is there something else wrong? Here is the JSP code: <td> <html:text size="10" maxlength="10" property="newrecnum"/><br> <html:text size="5" maxlength="5" property="newrectime"/> <html:select property="newreccode" disabled="true"> <html:option value="YES">YES</html:option> <html:option value="NO">NO</html:option></html:select> </td> I can include the ActionForm code as well if needed. Thanks!
