• No such signal... reviewImageReady (const QSize & imgSize, const QByteArray & imgData)

  Hello

  I have 2 questions:

  (Q1), what is the right way to implement the slot for the 'reviewImageReady' of the camera signal?

  Q2) after examination of the image, can the code prevents the image to be saved in the shared folder?

  For Q1, I get the following error log in my Console:

  Object::connect: No such signal bb::cascades::multimedia::QmlCamera::reviewImageReady(const QSize &imgSize, const QByteArray &imgData) in ../src/applicationui.cpp:125
  Object::connect:  (sender name:   'myCameraObj')
  

  In my applicationui.cpp I connect the signal and slot like this

      connectResult = connect(cameraObj,
              SIGNAL(reviewImageReady(const QSize &imgSize, const QByteArray &imgData)),
              this,
              SLOT(onReviewImageReady(const QSize &imgSize, const QByteArray &imgData))
              );
  

  and my onReviewImageReady slot looks like this

  Header:
  
  public slots:
    void onReviewImageReady(const QSize &imgSize, const QByteArray &imgData);
  
  Source file:
  
  void ApplicationUI::onReviewImageReady(const QSize &imgSize, const QByteArray &imgData)
  {
      Q_UNUSED(imgData);
      Q_UNUSED(imgSize);
  }//end onReviewImageReady
  

  Take off the SIGNAL() and SLOT() args arguments names. In other words, delete "imgSize" and 'imgData' and just keep to the types of arguments.

• There is no such thing as PushService createChannelCompleted signal

  Dear BlackBerry developers

  I am building an active push application. So I started with the PushService class to create a session and a channel and other things. Because I need the token server gives to my application, I need to connect with the createChannelCompleted (const bb::network:ushStatus status, const QString & token) signal. This signal is copy pasted from the documentation on here http://developer.blackberry.com/cascades/reference/bb__network__pushservice.html.

  But I always get the following error message

  Object::connect: No such signal PushManager::createChannelCompleted

  I tried all the ways to connect with the signal

  connect(pushService, SIGNAL(createChannelCompleted(const bb::network::PushStatus&, const QString&)), this, SIGNAL(createChannelCompleted(const PushStatus&, const QString&)));
  

  But I can't get it right, apparently.

  Thanks in advance!

  Hello

  This should work:

  QObject::connect(service, SIGNAL(createChannelCompleted(bb::network::PushStatus,QString)),
                       this, SLOT(onCreateChannelCompleted(bb::network::PushStatus,QString)));
  

  Statement of slot: / / upd: fixed a statement of slot

  void onCreateChannelCompleted(const bb::network::PushStatus &status, const QString &token);
  

  Your statement should probably also work if you replace second SIGNAL() SLOT() and use a full PushStatus in the slot. But for const const reference and & can be left inside the SIGNAL() and SLOT() statements. MOC will remove them automatically anyway.

• 500-100 wireless signal keeps dropping out.

  I just bought a brand new office of 500-100 a HP to replace my self built the aging of the desktop machine. The problem I have is that the signal wireless guard stall at random times, could be 3 times in 5 minutes, could be once in 30 minutes. My router is a Wirelss 5953 method.

  I've never had problems in the past with signal dropped, my phone and pad remain connected and the old pc used to be ok. Is that because I bought this machine that things started to go wrong.

  The intensity of such signal indicated by the bar remains at 4 all the time, then no reason (well, I guess that there must be a reason ) a little yellow exclamation point appears above him the connection limited to words. to get the connection works again, the only way is to disconnect and reconnect again.

  Suggestions anyone?

  PS. It happened again I wrote this...

  Thanks for the advice, but I fugured it myself after some trial and error. At HP support online for an hour, they took control of my desktop computer and change a few things, but it was always the same. So, I moved the pc into the room with the router and hard wired it in, no problems for 2 days.

  So I then unplugged and relied on the wireless, once again no problem for 2 days. Hmm.

  Returns the pc in the original piece and it cooled down the signal DESPITE a 4 bars signal and only 5 m away.

  So... in this new pc wireless card isn't obviously a top model of the line.

  Bought a booster wireless D-Link OfficeWorks (cheap) and plugged into a wall outlet in the same room as the pc,... There's been 2 weeks now and not a single drop out...

• Missing VIDEO signals for NOR-5762-(02)

  Hello

  I installed 15.1.1 FlexRIO, and I use it in LabVIEW FPGA 2013.

  

  I am trying to program the 5762 using the multi-sample CLIP: \Shared\FlexRIO\IO Modules\NI 5762\1.0.0\V5\NI5762MultiSampleClip\Ni5762MultiSampleClip.xml.

  By the November 2015 FlexRIO help, I think I'm supposed to use 'data clock/2' for IO nodes:

  

  However, there no such signal in the signal list when I add the CLIP:

  

  So, I followed what are probably mistakes typing in help FlexRIO next to the data signal clock/2 who say, 'IO Module clock 0 must be added to your project in the dialog box properties of the clock of basis of FPGA. The following signals shall be accessible in this area of the clock: I 0 N data, HAVE 0 N-1 data and HAVE 1 N N-1 AI 1 data data. » :

  

  I add IO Module 0 as a base clock clock to the project:

  

  And the dialog box above makes me think that IO Module clock 0 is compiled for 50 MHz, when I expect to be compiled at 250 MHz or 125 MHz.

  Exactly how should I clock AI0 AI1 multi-sample IO nodes in the LabVIEW diagram?

  Thank you

  Steve K

  Hi Steve,.

  Looking at your path to the XML CLIP code, it seems that you are using the 1.0.0 version of the CLIP.  This does not include the "Data Clock" signal and uses only IO Module clock 0/1.  There were a few additions in the latest CLIP who could have incompatible with Labview 2013, so only one can use the 1.0 version.  The CLIP of 1.0 is good to use; Simply use the clocks of Module e/s.

  The clock frequency listed in the IO Module clock 0 properties does not affect the frequency of compilation; the frequency is set by the constraints of the CLIP.  I think that this value is used sometimes when generating constraints for some paths, so I would still recommend the 125 MHz configuration.

  Documentation is really confusing, especially in cases like yours helps newer Flexrio with older Labview.

• emitting signals with QList as parameter?

  Hey developers

  How can I pass a QList as an argument with a signal? He repeats to me

  "No such signal ConnectionService::downloadCompleted (QList, QString) '.

  I'm emitting the signal with a QList object and a QString. It's my signal

  void downloadCompleted(const QList &connections, const QString &error);
  

  And that's how I connect

  connect(&this->connectionService, SIGNAL(downloadCompleted(QList, QString)), this, SLOT(searchCompleted(QList, QString)));
  

  I have allso tried QList SIGNAL signature. But that no longer works.

  Thanks in advance.

  Spend a full type, i.e.

  Connect (& connectionService, SIGNAL (downloadCompleted (const QList&, const QString &)), this, SLOT (searchCompleted (const QList&, const QString &)));)))

  'const' and '&' can be omitted if it should also work:

  Connect (& connectionService, SIGNAL (downloadCompleted (QList, QString)), this, SLOT (searchCompleted (QList QString,)));

  UPD:

  Try saving the type:

  qRegisterMetaType< QList >("QList");
  

• No bb::system:phone:Phone:callUpdated error signal

  I work on a project, use the phone object. It shows error when I connect the signal to a slot.

  bb::system::phone::Phone *ph = new bb::system::phone::Phone(this);
      bool success = connect(ph, SIGNAL(callUpdated(bb::system::phone::Call&)), this, SLOT(onCallUpdated(bb::system::phone::Call&)));
  

  It says: "Object::connect."
  "No such signal bb::system:: callUpdated (bb::system:: call &).

  Someone knows how to fix this?

  Please help me. Thank you

  Declare the slot as:

  void onCallUpdated(const bb::system::phone::Call &call);
  

  const is missing.

• There is no ContactPicker Signal for several ContactSelectionMode

  When I try to connect the signal "contactsSelected" of the ContactPicker to my own slot, I get:

  "Object::connect: no such signal bb::cascades:ickers::ContactPicker:contactsSelected(QList_ _&).

  QObject::connect(_contactPicker,
             SIGNAL(contactsSelected(QList &)),
             this,
             SLOT(onContactsSelected(QList &)));
  

  However, when I change the ContactPicker ContactSelectionMode "Single" and connect the signal "contactSelected" to my crack, it works very well (Contact is not the plural in this signal).

  It's the reference I used:

  http://developer.BlackBerry.com/Cascades/reference/bb__cascades__pickers__contactpicker.html#functio...

  Is it possible that the documentation for the signal name is incorrect?

  Hello

  Try declaring the slot as

      void onContactsSelected(const QList &contactIds);
  

  Change the connection to:

     QObject::connect(_contactPicker, SIGNAL(contactsSelected(QList)),
                       this, SLOT(onContactsSelected(QList)));
  

• Drop-down list of signal problem?

  DropDown *currency_dropdown = mSettings->findChild("dropdown_currency"); Q_ASSERT(currency_dropdown); bool ss = connect(currency_dropdown,SIGNAL(selectedValueChanged(const QVariant& selectedValue)), this, SLOT(onSettingsCurrencyChanged(const QVariant& selectedValue))); Q_ASSERT(ss);
  

  I'm on 10.1.0.1020

  When demand lanuch I

  Object::connect: No such signal bb::cascades::DropDown::selectedValueChanged(const QVariant& selectedValue) in ../src/applicationui.cpp:276
  

  is there a any error on my code?

  Thank you

  bool ss = QObject::connect(currency_dropdown, SIGNAL(selectedValueChanged(QVariant)), this,
   SLOT(onSettingsCurrencyChanged(QVariant)));
  

  This one should work.

  Do not specify a parameter names in SIGNAL() and SLOT(). Const and & can also be omitted when used together, MOC will reject them anyway. But it should work with them also.

• Contact SIGNAL not found

  I keep having problems with the alarm button of VisualNode. I connect to it as follows:

  QObject::connect(m_Title, SIGNAL(touch(TouchEvent *)),
                  this, SLOT(onTitleTouched(TouchEvent *)));
  

  The console spits the following error each time that you press the label:

  Object::connect: No such signal bb::cascades:Label:touch(TouchEvent_*) in... /SRC/xxxxxxx.cpp:121

  The objective here is to have a list where each item has more than one hitbox and performs a different action when everyone is hit.

  First, however, I must be able to connect to a key for a label in C++ event. Any ideas how this can be done successfully?

  For some reason any explicitly adding namespace (in spite of having included it in my source file) solved the problem:

      QObject::connect(m_Title, SIGNAL(touch(bb::cascades::TouchEvent*)),
                  this, SLOT(onTitleTouched(bb::cascades::TouchEvent*)));
  

• Signal connect problem

  Hi all

  I have a problem strange connection of signals to the slot machines. I have the following code:

  Container container = root->findChild ("timeline_container");
  m_pForeignWindow = (ForeignWindowControl *) (container-> at (0));

  m_pForeingWindow is not null here

  Boolean success = connect (m_pForeignWindow,
  SIGNAL (windowAttached (screen_window_t, const QString &, const QString &)),.
  This,
  SLOT (onWindowAttached (screen_window_t, const QString &, const QString &)));))

  success is true here

  success = QObject::connect (m_pForeignWindow,
  SIGNAL (touch(TouchEvent *)),
  m_timeline,
  CRACK (onTouch(TouchEvent *)));

  success is false here

  Research with the debugger, I got the following message:

  Object::connect: No such signal bb::cascades:ForeignWindowControl:touch(TouchEvent_*)

  but this signal exists for all objects in VisualNode... What I am doing wrong?

  Kind regards.

  See if it actually compiles.  FDI in the current beta version is infamous for being reported wrong these errors, so I suggest to turn them off.

  I want to set up a SystemListDialog but I get an error message

  Object::connect: No such signal bb::system:ystemListDialog::finished (SystemUiResult::Type) in... /SRC/CarsLogger.cpp:511

  Anyone have an example of using SystemListDialog?

  Hello! Use display names for the signals and slots:

  SIGNAL(finished(bb::system::SystemUiResult::Type))
  

  SLOT(onPromptFinished(bb::system::SystemUiResult::Type))
  

  p.s. It is not recommended to use "using namespace" in the .h files. This will pollute the namespace of each .cpp file that contains this header. It is better to use full names in the .h files and call "using namespace" in .cpp only.

• Try to get ListScrollStateHandler::onAtBeginningChanged (bool) to work.

  I use the SDK 10.1.0.1020

  What I'm trying to do, is to have an infinite scroll together so I need to detect when im trying to go beyond the bottom current and high current.  I tried to adjust the onAtBeginningChanged signal, but in the file log it says this:

  WARNING: Object::connect: no such signal bb::cascades:ListScrollStateHandler:nAtBeginningChanged (bool)

  If there is no why it compiles without errors?

  All other signals I've tried work well, I have them in the code like this:

  ListScrollStateHandler::create (myListView) .onAtEndChanged (this, SLOT (myListAtEnd (bool)));
  ListScrollStateHandler::create (myListView) .onAtBeginningChanged (this, SLOT (myListAtStart (bool)));
  ListScrollStateHandler::create (myListView) .onScrollingChanged (this, SLOT (myListScrolling (bool)));
  ListScrollStateHandler::create (myListView) .onFirstVisibleItemChanged (this, SLOT (myListFirstItem (QVariantList)));

  In addition, (slightly related) what is the difference with the following:

  LIstView * myList = LilstView:: create();

  and

  ListView * myList = new ListView;

  Yes, your second attempt is right: signals are indicated by the ListScrollStateHandler object. This is why you don't see more warnings.
  Now try the following code:

  ListScrollStateHandler *lssh = new ListScrollStateHandler(myListView);
  
  connect (lssh, SIGNAL (atEndChanged(bool)), this, SLOT (myListAtEnd(bool)));
  connect (lssh, SIGNAL (atBeginningChanged(bool)), this, SLOT (myListAtStart(bool)));
  

• SMS listening by using Cascades SmsTransport

  I'm having some trouble with the SmsTransport api. The listeners for phone and email are simple and work great, but when I try and listen for sms I get this runtime warning:
  
  Warning: Object::connect: No such signal bb::pim::message::SmsTransport::messageReceived(unsigned int, const
  bb::pim::message::Message&) in ../src/App.cpp:58
  
  and this is the code that is the problem:
  
       mSmsTransport->registerPort(0);
       connect(mSmsTransport, SIGNAL(messageReceived(unsigned int, const bb::pim::message::Message&)), SLOT(handleSms(unsigned int, const bb::pim::message::Message&)));
  
  Maybe the method signature has changed from what is listed here?
  https://developer.blackberry.com/cascades/reference/bb__pim__message__smstransport.html
  
  Also related to this.. is 0 the correct port to register on to listen for SMS's? It worked this way on Java BB but I'm not sure about BB10.
  

  Patch the SDK to C:\devel\bbndk\target_10_0_9_2318\qnx6\usr\include\bb\pim\message\MessageUpdate.hpp and adding the line to the bottom of the file solves the problem. Not sure how it works for you, unless you have this line.

• Your special SPA122, if the caller hangs up

  Hello

  I'm new to the SPA122 and have a problem. If a call is active, and the caller hangs up, I don't get a tone as I expect, he just hangs up and replay the tone.

  I expect as a tone - tut-tut-tut-tut-that stops that, if I hang up the call also.

  I can't find a tone in the locale, where I can change this.

  You have any ideas?

  Concerning

  Manual

  It seems that you have set up a CPC, but phone is not honor such signal.

  The configuration of SPA122 must match all of the features supported by phone.

  Disable the CPC ( CPC duration to zeroset), and then try again.
