method object never called

• Method is never triggered.

  I do some indepth BB10 development tutorials as I learn myself. Especially for beginners and for those coming to BB Android/Java Dev.

  In any case, I'm my current tutorial I want to talk about networking and FIO. So far I have not all errors in compiling or running the application however watch console I do not get an expected debug output.

  My code:

  Download.HPP (my class managed file download):

  #ifndef DOWNLOAD_HPP_
  #define DOWNLOAD_HPP_

  #endif /* DOWNLOAD_HPP_ */
  

  The Download.cpp:

  #include "Download.hpp"

    // 5. fileDownload() method is triggered upon compleated download
    // 6. fileDownload() emits a signal to observing classes

  Download::~Download(){}

    // setChanged() and notifyObservers() methods to tell all classes
    // who are registered as listeners that our file has been downloaded
    emit downloaded();
  }
  
  // Simple getter method for received data
  QByteArray Download::downloadedData() const
  {
    return data;
  }
  

  And my applicationui.cpp

  #include "applicationui.hpp"
  
  #include 
  #include 
  #include 
  #include 
  
  // Import our download service class
  #include "Download.hpp"
  
  using namespace bb::cascades;
  
  ApplicationUI::ApplicationUI(bb::cascades::Application *app) :
          QObject(app)
  {
      // prepare the localization
      m_pTranslator = new QTranslator(this);
      m_pLocaleHandler = new LocaleHandler(this);
  
      bool res = QObject::connect(m_pLocaleHandler, SIGNAL(systemLanguageChanged()), this, SLOT(onSystemLanguageChanged()));
      // This is only available in Debug builds
      Q_ASSERT(res);
      // Since the variable is not used in the app, this is added to avoid a
      // compiler warning
      Q_UNUSED(res);
  
      // initial load
      onSystemLanguageChanged();
  
      // Create scene document from main.qml asset, the parent is set
      // to ensure the document gets destroyed properly at shut down.
      QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

      connect(&down, SIGNAL(downloaded()), SLOT(showNotice()));

  // Shows message once Download class emmits a signal
  // that file download has been compleated
  void ApplicationUI::showNotice()
  {
    // Show notice in debug console
    qDebug("FILE DOWNLOAD COMPETE");
  }
  

  And applicationui.hpp

  class ApplicationUI : public QObject
  {
    Q_OBJECT
    public:
      ApplicationUI(bb::cascades::Application *app);
      virtual ~ApplicationUI() { }
  
    private slots:
      void onSystemLanguageChanged();
      // We will treat ApplicationUI as our Main Activity class
      // thus it will be observing our Download class. Once
      // we are notified that our download is complete we want to
      // do something with that data for now just display the message.
      void showNotice();
  

  In my applicationui.cpp in the constructor I create a new instance of download and request a download on successful download showNotice(); method must be triggered despite no error that the showNotice method is never executed because qDebug line is never displayed.

  To expand my question:

  Once a file is downloaded by programming where is the stored file and can we specify our own destenation or is the file stored under downloads folder automatically?

  You represent download like local and end of the function will be thus destroyed as well as the connection.

  Try to declare on the job not the battery. that is of new Download();

  Wherever you get your http response I think that it's already been destroyed.

• Attachment Manager never called

  I need to open and analyze an attachment to the message. But I never have the opportunity to download an attachment.

  Installation program:

  -during the performance in the simulation using Eclipse 1.0 eJDE.

  -J' tried to run in the 4.7.0.46 and the 4.5.0.16 component packages

  -J' use the simulator of the ESS to send emails with attachments to the Simulator.

  -attachment file I tried names "Lists2.iif" and also "x-rimdevice - Lists2.iif.

  -the file is a simple text file, a little less than 10 KB in size.

  Comments:

  -l'email is always received with the attachment.

  -the menu, the option to open the attachment doesn't work or call my attachments Manager

  -None of the members of my call handler.

  Code:

  -J' tried to get this working using the ChapiDemo as a model so that the Attachment Manager old as described in the article DB-00475 Knowledge Base and I get the same result in both cases.

  -I am currently trying to get this to work with the Attachment Manager.

  I walked through my registration code that runs when the system starts successfully.

            // Register an attachment handler to read attachments of iif type.
            AttachmentHandlerManager ahm = AttachmentHandlerManager.getInstance();
            ahm.addAttachmentHandler(new IIFAttachmentHandler());
  

  The handler code is below and none of the methods called;

  public class IIFAttachmentHandler implements AttachmentHandler {
  
    /* (non-Javadoc)
     * @see net.rim.blackberry.api.mail.AttachmentHandler#menuString()
     */
    public String menuString() {

        rc = true;
      }
      return rc;
    }
  
  }
  

  Issues related to the:

  1. it is even possible to get this working in simulation? If so, I'm missing a component any attachment downloader?

  2. given the code above suggestions on how to fix or debug code? As I say it's having saved ok, but never called.

  3. If I come back to try to get this to work using the approach of the JSR 175 ChapiDemo, would it even work for a defined application as CLDC or the app should be defined as a MOPED.

  Thanks in advance.

  I changed the file name of 'x-rimdevice' - Lists2.iif to "x - rimdeviceLists2.iif" and now my media method is called. It has a bug in the way if calculates press it, but it is a different matter.

  I have this will mark it as resolved, but if someone can always answer to question 3 to see if the application has a moped or not not to use Manager JSR175 of content, that would be greatly appreciated because my preference is to use this approach.

• extend ListField, how to get a valid result of getSelectedIndex inside the method object?

  Hi all

  I have replace the method object to extend ListField to create my own color ListField.

  I need to avoid the double drawRow between the method object

  and the drawFocus() method.

  inside the method object, I always get the 'bad' selectedIndex (previous)

  (or rectangular previous on getFocusRect()).

  my questions are:

  1. how to get current selectedIndex (or FocusRect) inside the method object when we extend ListField?

  2. is there any other method called before object, the method which returns SelectedIndex valid?

  3. how to avoid the double drawing between object and drawFocus()?

  Thank you.

  If everything you do is add your own color, and then you can do this by using a fillRect in the drawListRow method.  In there.  I have the code that did this, but only for lines not targeted, as it detects with:

  If (listField.getSelectedIndex ()! = index) {}

  //

  }

• PSSigValGetAPLabelProc callback is never called, why?

  I understand DigSig example and I'm going to convert it to a proper dig signature plugin. So far I got the creation of GIS to dig, the validation and the creation of GIS satisfactory appearance, but what I don't understand is why my registered PubSec (Acrobat 9 sdk example) both call of the plugin back are never called.

  They are: PSSigValGetAPLabelProc and PSGetLogoProc. In fact, I need to be able to update the n1 and n3 layers according to the validation of signature whenever a PDF file is opened. Documentation, I learned that the reminders above is where should I put my code.

  In SigCreateAPNXObj callback, there is a comment:

  You must have generated if you want your PSSigValGetAPLabelProc callback called n1 and n3

  From there, I figured I should at least specify n1 or n3. So I added the layer no. 1 in this method, as follows:

  xObjArray [0] = DigSigAPXObjectFromLogo (cosDoc, stmUnknownData, 0, stmUnknownBBox & bboxRec);

  but still PSSigValGetAPLabelProc is not called (I m debugging plugin btw). I checked that this call back is in record time as well.

  Well want to, help me.

  Therefore #5 is not an option - you'll need to have this deleted requirement given that you cannot accomplish.  I would also delete #6 as well as it's a BAD IDEA for many reasons.   All the others are fine.

• DSHandler::GetLogo never called in DocSign

  Hi all

  I noticed a small problem with the plugin DocSign example comes from the 9.1 SDK: custom signature logos (respectively the green check, Red Cross and the yellow question mark) are never displayed and are instead replaced by... a yellow question mark. I have first if it was the question of the status of 'unknown' signature mark, but after investigation, it seems that the method DSHandler::GetLogo is, in fact, never called at all.

  As I change anything to the code source DocSign, and since then he has worked well with other users, I guess it must be some sort of bug in the current version of adobe acrobat.

  "Build" the plugin on Windows XP with VS9, and I tested it on Windows Vista with the trial versions of Adobe Acrobat Pro and Acrobat Pro Extended Adobe updated.

  Anyone know a work around?

  Thank you
  M.H.

  No, you can't wait for that.

• What happens when ClearTask is never called?

  I use a NOR-6259 with the C API of Linux. What happens when a task program is interrupted and the ClearTask function is never called? Is it possible to query the driver for all running tasks, or better yet, is it possible I can assure that the device reset to a base state?

  In particular in the development, it is nice to be able to simply CTRL-C or something like that to kill a program bug.

  I don't think there is a good way to do it using our C API. If it was on a Windows machine, we have a program called MAX which will allow you to reset the device from there, but I don't think it is available on Linux. I think the only way is to reset the device.

• MenuItems run() method that is called from the thread eventdispatching?

  Hello

  is it? I know that MenuItem itself extends thread, but I wonder why this method is called run() and finally and above all it would'nt be worse if this method would be called from a Thread.

  THX

  In fact the menu items are run on the thread of the event. You can see this by creating a menu item long-term. The menu will not close and will not refresh the screen.

• Error caused by the overrided method object build

  Hello world

  When I build my Active blackberry Setup, I get the error:

  I/O Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specifiedrapc executed for the project MyApplication
  

  This happens when I have this code:

  LabelField lblTitle = new LabelField(title) {
      protected void paint(Graphics graphics) {
          graphics.setColor(0x00FFFFFF);
          graphics.clear();
          super.paint(graphics);
      }
  };
  LabelField lblSubTitle = new LabelField(releaseYear + ", " + rating) {
      protected void paint(Graphics graphics) {
          graphics.setColor(0x00FFFFFF);
          graphics.clear();
          super.paint(graphics);
      }
  };
  
  vfmHeader.add(lblTitle);
  vfmHeader.add(lblSubTitle);
  screen.add(vfmHeader);
  

  If I had to remove the method object overrided in the LabelField lblSubTitle, however, the build error does not. I tried to change a LabelField to a RichTextField lblSubTitle, and I still get the same error.

  Very strange. Anyone know why this is happening? Thank you!

  I found the solution to my problem here:

  http://www.BlackBerryForums.com/rim-software/79668-JDE-build-all-problem.html

  Basically, I removed all older versions of Java that I had and I installed this following:

  J2SDK-1_4_2_15-windows-i586 - p.exe (JDK 1.4.2 version 15)
  JDK-1_5_0_12-windows-i586 - p.exe (JDK 1.5.0 version 12)

  JDK 1.5.0 is necessary because otherwise the JDE Eclipse plug-in will not start with 1.4.2.

  Without having the JDK 1.6, however, the MDS - CS will organize not (within Eclipse). I had to manually download "BlackBerry email and MDS 4.14 Service simulators", start it and then run my application.

  I hope this can help someone down the line...

• g.clear () call to the method object refuses the development of drawing for checkbox

  Hello

  I have this custom field extend the CheckboxField, with him object method is overloaded as follows:

  protected void paint (Graphics g)
  {
  int bgColor = _fontStyle.getBackgroundColor ();
  If (bgColor! = - 1).
  {
  g.setBackgroundColor (_fontStyle.getBackgroundColor ());
  g.Clear ();
  }
  g.setColor (_fontStyle.getForegroundColor ());
  Super.Paint (g);
  }

  the _fontSytle is defined by the user and transmitted as a reference of custom style, everything works fine in a first time without g.clear (), but I soon found out when the background color is black, while the foreground is white, paint reverse color. So I added this g.clear () and the problem was solved.

  However, the compensation seems to graphics here refuses the development of drawing and I was not able to trace which is cleaned and what is the indicator for the development of design. BTW, the "g.isDrawingStyleSet (Graphics.DRAWSTYLE_FOCUS)" returns true.

  So I was wondering if anyone here can provide a diagnosis on what could be the cause and how to fix it. Thanks in advance.

  Christian

  Nope, the g.clear () must be called to display the colors correctly. As I said, it can work in some cases, but just mess up from time to time.

  So what I do now is take a workaround to override the drawFocus() as default

  protected void drawFocus(Graphics g, boolean on)
      {
          refreshFooter(on ? getLabel() : "");
          // customize draw focus logic here as the default one conflicts with the paint method
          XYRect rec = new XYRect();
          getFocusRect(rec);
          g.invert(rec);
      }
  

  Thus the development of drawing must rely on paint and so don't mess the color.

  In any case, thanks much for the reply!

  We see this code in your constructor?.

  I guess you really want to say this thread is 'start '.  Don't forget that

  does not run a Thread, it executes the run() method in the Thread.  To start a separate Thread, you must use

  . Shart().

• Microsoft never call their users? I just got a call from someone who said they were from Microsoft and he wanted me to run something.

  I just got a call from someone who said they were from Microsoft. It was obviously of the India. In any case, he said that there are problems with my computer and it asked me to do something, I would not.  He hung up. He told me to click the button of windows on my keyboard. Then he told me type something in and running. But I refused. I said, how end I call Microsoft and give them your name... HE HUNG UP.

  Hello DianeMcGettigan,

  It is simply one of the many scams that are doing the tour.

  Unless you have a prepaid support contract with Microsoft, then Microsoft will never contact you by phone, mail or e-mail about problems with your PC. You did while refusing to allow him access to your PC. All they want to do is to have access to your PC, so they can steal personal data (banking etc.) on your part.

  This forum post is my own opinion and does not necessarily reflect the opinion or the opinion of Microsoft, its employees or other MVPS.
