  • jsf messed up links

    - by Mateusz
    I'm new to JSF. My application is working, but I'm confused with links in browser when using controller. BTW, there is also PrimeFaces in my app so don't be suprised with p: tags. Let's say I have 'list' and 'show' pages with controller doing redirection between them. First I'm on http://localhost:8080/y/r/conversation/list.xhtml page. There is link created with line <p:commandLink action="#{lazyConversationBean.doShow(conv)}" ajax="false" value="View"/>. lazyConversationBean acts here as my Controller. There is method: public String doShow(Conversation c) { this.setSelectedConversation(c); return "view"; } from which I got redirected to ...... again http://localhost:8080/y/r/conversation/list.xhtml (browser shows it) even when it's correct http://localhost:8080/y/r/conversation/view.xhtml page. There I have link <p:commandButton action="#{lazyConversationBean.doList()}" ajax="false" value="Back to list"/> and again controller has method: public String doList() { return "list"; } from which I got redirected to ... yeah, you guessed right ... http://localhost:8080/y/r/conversation/view.xhtml (that is again what browser shows) even when again it is correct http://localhost:8080/y/r/conversation/list.xhtml page. It seams as browser link area is always one step behind page currently being displayed. I don't even know if it's some incorrect behaviour as I have no idea how to query google for this :D Just for test I did this short tutorial, where netbeans created whole stack of code on one of my entities, and behaviour was the same, so it's not PrimeFaces magic related. Can you tell my why it happens, and how to fix it? Users likes to copy correct links ;)

  • Paypal Encrypted Website payments

    - by John Isaacks
    I am trying to integrate a PayPal Website Payments Standard Cart Upload payment type into my shopping cart. I integrated Google Checkout a while back and I did not find it overly confusing as I do paypal. I am getting info on how to encrypt it from here: https://cms.paypal.com/us/cgi-bin/?&cmd=_render-content&content_ID=developer/e_howto_html_encryptedwebpayments#id08A3I0P017Q Paypal says I need to generate a private key and a public certificate using OpenSSL. I went to OpenSSL and downloaded the latest release, which is just a folder containing various files but I see no application I can use, not sure what to do here. Even if I were to get OpenSSL to generate me a private key and public cert, the next step is to download either an MS or Java command line tool to create the encrypted cart ahead of time with the cart-total, tax, etc. which sounds crazy to me, like I am supposed to manually do this prior to every order?? Obviously I do not know the items in the cart the customer is going to buy before hand so I need this to be done on the fly on my website using PHP. But I am completely lost. There has to be a way to setup dynamic secure cart uploads to paypal. Can someone please point me in the right direction?

  • How do I simulate "In" using Linq2Sql

    - by flipdoubt
    I often find myself with a list of disconnected Linq2Sql objects or keys that I need to re-select from a Linq2Sql data-context to update or delete in the database. If this were SQL, I would use IN in the SQL WHERE clause, but I am stuck with what to do in Linq2Sql. Here is a sample of what I would like to write: public void MarkValidated(IList<int> idsToValidate) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate).ToList(); foreach(var item in items) item.Validated = DateTime.Now; _Db.SubmitChanges(); } // Disposes of DataContext } Or: public void DeleteItems(IList<int> idsToDelete) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate); _Db.Items.DeleteAllOnSubmit(items); _Db.SubmitChanges(); } // Disposes of DataContext } Can I get this done in one trip to the database? If so, how? Is it possible to send all those ints to the database as a list of parameters and is that more efficient than doing a foreach over the list to select each item one at a time?

  • How to take advantage of an auto-property when refactoring this .Net 1.1 sample?

    - by Hamish Grubijan
    I see a lot of legacy .Net 1.1-style code at work like in example below, which I would like to shrink with the help of an auto-property. This will help many classes shrink by 30-40%, which I think would be good. public int MyIntThingy { get { return _myIntThingy; } set { _myIntThingy = value; } } private int _myIntThingy = -1; This would become: public int MyIntThingy { get; set; } And the only question is - where do I set MyIntThingy = -1;? If I wrote the class from the start, then I would have a better idea, but I did not. An obvious answer would be: put it in the constructor. Trouble is: there are many constructors in this class. Watching the initialization to -1 in the debugger, I see it happen (I believe) before the constructor gets called. It is almost as if I need to use a static constructor as described here: http://www.c-sharpcorner.com/uploadfile/cupadhyay/staticconstructors11092005061428am/staticconstructors.aspx except that my variables are not static. Java's static initializer comes to mind, but again - my variables are not static. http://www.glenmccl.com/tip_003.htm I want to make stylistic but not functional changes to this class. As crappy as it is, it has been tested and working for a few years now. breaking the functionality would be bad. So ... I am looking for shorter, sweeter, cuter, and yet EQUIVALENT code. Let me know if you have questions.

  • Extension methods for encapsulation and reusability

    - by tzaman
    In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself?

  • Android App - disappearance of app GUI

    - by Radek Šimko
    I'm trying to create a simple app, whose main task is to open the browser on defined URL. I've created first Activity: public class MyActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.main); Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://my.url.tld")); startActivity(myIntent); } Here's my AndroidManifest.xml: <manifest ...> <application ...> <activity android:name=".MyActivity" ...> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> This code is fully functional, but before it opens the browser, it displays a black background - blank app GUI. I didn't figured out, how to go directly do the browser (without displaying the GUI). Anyone knows?

  • Messages not forwarded to error queue when exception is thrown in handler (it works on my machine)

    - by darthjit
    e are using NServicebus 4.0.5 with sql server(sql server 2012) as transport. When the handler throws an exception, NSB does not retry or move the message to the error queue. Successful messages make it to the audit queue but the failed/errored ones don't! . Interestingly, all this works on our local machines(windows 7 ,sql server localdb) but not on windows server 2012 (sql server 2012). Here is the config info on the subscriber: <add name="NServiceBus/Transport" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <add name="NServiceBus/Persistence" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <MessageForwardingInCaseOfFaultConfig ErrorQueue="error" /> <UnicastBusConfig ForwardReceivedMessagesTo="audit"> <MessageEndpointMappings> <add Assembly="Services.Section.Messages" Endpoint= "Services.ACL.Worker" /> </MessageEndpointMappings> </UnicastBusConfig> And in code it is configured as follows: public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization { public void Init() { IContainer container = ContainerInstanceProvider. GetContainerInstance(); Configure .Transactions.Enable(); Configure.With() .AutofacBuilder(container) .UseTransport<SqlServer>() .Log4Net() //.Serialization.Json() .UseNHibernateSubscriptionPersister() .UseNHibernateTimeoutPersister() .MessageForwardingInCaseOfFault() .RijndaelEncryptionService() .DefiningCommandsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Commands")) .DefiningEventsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Events")) .UnicastBus(); } } Any ideas on how to fix this? here is the log info (there is a lot there, search for error to see the relevant parts) https://gist.github.com/ranji/7378249

  • Handle order dependence in loops

    - by Matt
    Hey all, I'm making a templating system where I instantiate each tag using a foreach loop. The issue is that some of the tags rely on each other so, I'm wondering how to get around that ordering from the looping. Here's an example: Class A { public $width; __construct() { $this->width = $B->width; // Undefined! Or atleast not set yet.. } } Class B { public $width; __construct() { $this->width = "500px"; } __tostring() { return "Hello World!"; } } Template.php $tags = array("A", "B"); foreach ($tags as $tag) { $TagObj[$tag] = new $tag(); } echo $TagObj['A']->width; // Nadamundo! EDIT: Ok just to clarify.. My main problem is that Class A relies on Class B, but class A is instantiated before class B, so therefore width has not yet been defined in class B. I am looking for a good way to make sure all the classes are loaded for everyone allowing the interdependencies to exist. For the future, please don't consider any syntax errors.. I just made up this example on the spot. Also assume that I have access to class B from class A after class B gets instantiated. I know this has applications elsewhere and I'm sure this has been solved before, if someone could enlighten me or point me in the right direction that'd be great! Thanks! Matt Mueler

  • 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

  • How do I [legally] get the current first responder on the screen on an iPhone?

    - by Anthony D
    I submitted my app a little over a week ago and got the dreaded rejection email today. It reads as follows: Dear -----------, Thank you for submitting --------- to the App Store. Unfortunately it cannot be added to the App Store because it is using a private API. Use of non-public APIs, which as outlined in the iPhone Developer Program License Agreement section 3.3.1 is prohibited: "3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs." The non-public API that is included in your application is firstResponder. Regards, iPhone Developer Program Now, the offending API call is actually a solution I found here on SO: UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow]; UIView *firstResponder = [keyWindow performSelector:@selector(firstResponder)]; So this is my question; How do I get the current first responder on the screen? I'm looking for a legal way that won't get my app rejected. Thanks. I figured this out based on the solution provided by Thomas below. Here is what the final code looks like: @implementation UIView (FindFirstResponder) - (UIView *)findFirstResonder { if (self.isFirstResponder) { return self; } for (UIView *subView in self.subviews) { UIView *firstResponder = [subView findFirstResonder]; if (firstResponder != nil) { return firstResponder; } } return nil; } @end

  • Dynamically added JTable not displaying

    - by Graza
    Java Newbie here. I have a JFrame that I added to my netbeans project, and I've added the following method to it, which creates a JTable. Problem is, for some reason when I call this method, the JTable isn't displayed. Any suggestions? public void showFromVectors(Vector colNames, Vector data) { jt = new javax.swing.JTable(data, colNames); sp = new javax.swing.JScrollPane(jt); //NB: "this" refers to my class DBGridForm, which extends JFrame this.add(sp,java.awt.BorderLayout.CENTER); this.setSize(640,480); } The method is called in the following context: DBGridForm gf = new DBGridForm(); //DBGridForm extends JFrame DBReader.outMatchesTable(gf); gf.setVisible(true); ... where DBReader.outMatchesTable() is defined as static public void outMatchesTable(DBGridForm gf) { DBReader ddb = new DBReader(); ddb.readMatchesTable(null); gf.showFromVectors(ddb.lastRsltColNames, ddb.lastRsltData); } My guess is I'm overlooking something, either about the swing classes I'm using, or about Java. Any ideas?

  • ASP.NET MVC Posted date field comes in as 1/1/0001

    - by engil
    Just started working with .NET and MVC(1). I'm having a problem wherein in my add action the entered date for some reason ends up as 1/1/0001 instead of what is entered thus causing a date overflow. In my model, this field ("Added") is is of type datetime and does not allow nulls. In my controller I have: public ActionResult Add() { Instance instance = new Instance() { Added = DateTime.Now, Active = true }; return View(instance); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Add(Instance instance) { if (ModelState.IsValid) { try { System.Diagnostics.Trace.Write("test"); instanceRepository.Add(instance); instanceRepository.Save(); return RedirectToAction("Details", new { id = instance.InstanceID }); } catch { ModelState.AddRuleViolations(instance.GetRuleViolations()); } } return View(instance); } And in my view I have: <div class="editor-label"> <%= Html.LabelFor(model => model.Added) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Added,String.Format("{0:g}",Model.Added))%> <%= Html.ValidationMessageFor(model => model.Added) %> When I first go to Instances/Add the default value is set correctly, however as soon as I submit the date turns into 1/1/0001 (from my understanding this indicates that it was either null or in an unrecognizable format) When I debug and palce a watch on Request.Form I see the date coming in encoded ie Request.Form {Added=4%2f9%2f2010+8%3a24%3a39+AM} - is this an issue? I know its probably not enough information to make a conlusive determination on why this is failing, but if someone could provide some good debugging tips on how to determine where the submitted date is getting munged I'd really appreciate it.

  • Are MEF's ComposableParts contracts instance-based?

    - by Dave
    I didn't really know how to phrase the title of my questions, so my apologies in advance. I read through parts of the MEF documentation to try to find the answer to my question, but couldn't find it. I'm using ImportMany to allow MEF to create multiple instances of a specific plugin. That plugin Imports several parts, and within calls to a specific instance, it wants these Imports to be singletons. However, what I don't want is for all instances of this plugin to use the same singleton. For example, let's say my application ImportManys Blender appliances. Every time I ask for one, I want a different Blender. However, each Blender Imports a ControlPanel. I want each Blender to have its own ControlPanel. To make things a little more interesting, each Blender can load BlendPrograms, which are also contained within their own assemblies, and MEF takes care of this loading. A BlendProgram might need to access the ControlPanel to get the speed, but I want to ensure that it is accessing the correct ControlPanel (i.e. the one that is associated with the Blender that is associated with the program!) This diagram might clear things up a little bit: As the note shows, I believe that the confusion could come from an inherently-poor design. The BlendProgram shouldn't touch the ControlPanel directly, and instead perhaps the BlendProgram should get the speed via the Blender, which will then delegate the request to its ControlPanel. If this is the case, then I assume the BlendProgram needs to have a reference to a specific Blender. In order to do this, is the right way to leverage MEF and use an ImportingConstructor for BlendProgram, i.e. [ImportingConstructor] public class BlendProgram : IBlendProgram { public BlendProgram( Blender blender) {} } And if this is the case, how do I know that MEF will use the intended Blender plugin?

  • Is nested synchronized block necessary?

    - by Dan
    I am writing a multithreaded program and I have a method that has a nested synchronized blocks and I was wondering if I need the inner sync or if just the outer sync is good enough. public class Tester { private BlockingQueue<Ticket> q = new LinkedBlockingQueue<>(); private ArrayList<Long> list = new ArrayList<>(); public void acceptTicket(Ticket p) { try { synchronized (q) { q.put(p); synchronized (list) { if (list.size() < 5) { list.add(p.getSize()); } else { list.remove(0); list.add(p.getSize()); } } } } catch (InterruptedException ex) { Logger.getLogger(Consumer.class.getName()).log(Level.SEVERE, null, ex); } } } EDIT: This isn't a complete class as I am still working on it. But essentially I am trying to emulate a ticket machine. The ticket machine maintains a list of tickets in the BlockingQueue q. Whenever a client adds a ticket to the machine, the machine also keeps track of the price of the last 5 tickets (ArrayList list)

  • Why the composite component fails to parent controls?

    - by lyborko
    Hi, I created my own Component : TPage , which Contains Subcomponent TPaper (TPanel). The problem is, that when I put controls such as TMemo or TButton on the TPaper (which fills up nearly whole area), the controls do not load at all. see example below TPaper = class(TPanel) protected constructor Create(AOwner: TComponent);override; destructor Destroy;override; public procedure Paint; override; end; TPage = class(TCustomControl) private FPaper:TPaper; protected procedure CreateParams(var Params:TCreateParams); override; public constructor Create(AOwner: TComponent);override; destructor Destroy;override; published property Paper: TPaper read FPaper write FPaper; end; constructor TPage.Create(AOwner: TComponent); begin inherited Create(AOwner); PaperOrientation:=poPortrait; PaperSize:=psA4; PaperBrush:=TBrush.Create; PaperBrush.Color:=clWhite; PDFDocument:=Nil; FPaper:=TPaper.Create(Self); FPaper.Parent:=Self; FPaper.SetSubComponent(True); end; ... Memo1 is parented in TPaper (TPanel) at design-time, but after pressing "Run" it does not exist. procedure TForm1.btn1Click(Sender: TObject); begin if not Assigned(Memo1) then ShowMessage('I do not exist'); //Memo1 is nil end; Have you any idea what's wrong? Thanks a lot P.S Delphi 7 When I put TMemo inside TPaper and save the unit (Unit1), after inspection of associated dfm file, there is no trace of TMemo component. (Thats why it can not load to app.)

  • accessing widgets inside a GWT element

    I want to access the text elements inside this textbox in GWT from the main method (where I call it like this) DialogBox aBox = newCandidatePop.buildNewElecPopup(); aBox.center(); aBox.getWidget(); MiscUiTools.newCandidateHandler(aBox.firstName, aBox.surName); in newCandidateHandler i want to attach a click handler to the two text boxes However, the above doesnt quite work - I cant get access to the aBox.firstName elements because they are static methods -- I am wondering what is best practice, how would you code something like this up? static TextBox firstName = new TextBox(); static TextBox surName = new TextBox(); static DialogBox box; // public newCandidatePop() { // box = buildNewElecPopup(); // } static public DialogBox buildNewElecPopup() { DialogBox box = new DialogBox(); box.setAutoHideEnabled(true); box.setText("Add a New Candidate"); box.setAnimationEnabled(true); box.setGlassEnabled(true); Grid dialogGrid = new Grid(2, 3); dialogGrid.setPixelSize(250 , 125); dialogGrid.setCellPadding(10); dialogGrid.setWidget(0, 0, new HTML("<strong>First Name</strong>")); dialogGrid.setWidget(0, 1, firstName); dialogGrid.setWidget(1, 0, new HTML("<strong>Surname</strong>")); dialogGrid.setWidget(1, 1, surName); box.add(dialogGrid); return box; }

  • Unable to step into interface implementation configured by unity application block

    I have configured a set of interface implementations with EntLib. unity block. The constructor of implementation classes work fine as soon as I run the application: 1. The interface to implement when I run the application the cctor runs fine, which shows that unity resolution was successful: But when I try to call a method of this class, the code just passes through without actually invoking the function of the implemented class: Edit: Added on June 11, 2012 Following is the Unity Configuration I have. (This is all the unity configuration I am doing) public class UnityControllerFactory : DefaultControllerFactory { private static readonly IUnityContainer container; private static UnityControllerFactory factory = null; static UnityControllerFactory() { container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Configure(container); factory = new UnityControllerFactory(); } public static UnityControllerFactory GetControllerFactory() { return factory; } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { return container.Resolve(controllerType) as IController; } } I am unable to step into this code and the implementation simply skips out without executing anything. What is wrong here?

  • How to update a property using Type.GetProperties() method?

    - by Richard77
    Hello, I've a collection of a class' properties and would like to update each one's value by iterating over the collection through the index. 1) I create the collection of properties this way private PropertyInfo[] GetPropertiesOfMyClass() { Type myType = (typeof(myClass)); PropertyInfo[] PropertyInfoArray = myType.GetProperties( BindingFlags.Public | BindingFlags.Instance); return PropertyInfoArray; } 2)Now, I'd like to set up the value of each one depending on the index this way public void UpdateProperty(MyClass instanceOfMyClass, string valueToUpdate, int index) { //TODO: //1. Get an individual property from the GetPropertyOfMyClass() using index //2. Update the value of an individual property of the instanceOfMyClass } I'd like to be able to call UpdateProperty from a Controller like this: UpdateProperty(instanceOfMyClass, valueToUpdate, indexOfTheProperty); Honestly, I do not know how to involve the instanceOfMyClass in the game as GetProperty only plays with myClass. Since I saw that I can use Name, PropertyType, ... to get information on the property. So, I've tried also GetPropertyOfMyClass()[index].SetValue(...), but I was lost in the arguments of its constructor, so I abandoned. What I want is to be able to update the value of a property in my collection just by using the index. Thanks for helping

  • Trouble bringing a Blackberry App to Foreground

    - by Luis Armando
    I have an app that is listening in background and when the user clicks "send" it displays a dialogue. However I need to bring my app to foreground so the user answers some questions before letting the message go. but I haven't been able to do this, this is the code in my SendListener: SendListener sl = new SendListener(){ public boolean sendMessage(Message msg){ Dialog myDialog = new Dialog(Dialog.D_OK, "message from within SendListener", Dialog.OK,Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION), Dialog.GLOBAL_STATUS) { //Override inHolster to prevent the Dialog from being dismissed //when a user holsters their BlackBerry. This can //cause a deadlock situation as the Messages //application tries to save a draft of the message //while the SendListener is waiting for the user to //dismiss the Dialog. public void inHolster() { } }; //Obtain the application triggering the SendListener. Application currentApp = Application.getApplication(); //Detect if the application is a UiApplication (has a GUI). if( currentApp instanceof UiApplication ) { //The sendMessage method is being triggered from //within a UiApplication. //Display the dialog using is show method. myDialog.show(); App.requestForeground(); } else { //The sendMessage method is being triggered from // within an application (background application). Ui.getUiEngine().pushGlobalScreen( myDialog, 1, UiEngine.GLOBAL_MODAL ); } return true; } }; store.addSendListener(sl); App is an object I created above: Application App = Application.getApplication(); I have also tried to invoke the App to foreground using its processID but so far no luck.

  • Swig C++ Lua Pass class by reference

    - by Jeremy
    I don't know why I'm having a hard time with this. All I want to do is this: class foo { public: foo(){} ~foo(){} float a,b; }; class foo2 { public: foo2(){} foo2(const foo &f){*this = f;} ~foo2(){} void operator=(const foo& f){ x = f.a; y = f.b; } float x,y; }; /* Usage(cpp): foo f; foo2 f2(f); //or using the = operator f2 = f; */ The problem I'm having is that, after swigging this code, I can't figure out how to make the lua script play nice. /* Usage(lua) f = example.foo() f2 = example.foo2(f) --error */ The error I get is "Wrong arguments for overloaded function 'new_Foo2'": Possible c/c++ prototypes are: foo2() foo2(foo const &) The same thing happens if I try and use do f2 = f. As I understand it everything is stored as a pointer so I did try adding an additional constructor that took a pointer to foo but to no avail.
