• AxesOrientationMode has not been declared?

  I have a project of cascades c ++ which uses QCompass.  I understand the at the top of the hpp file.  I have a compass to level class named m_compass.

  In the pro file, I added the CONFIG += mobility and sensors += MOBILITY

  In the cpp file, I have this:

  // at the top
  using namespace QtMobility;
  //...
  // in the constructor
  m_compass->setAxesOrientationMode(AxesOrientationMode::FixedOrientation);
  

  It gives me the error:

  'AxesOrientationMode' has not been declared
  

  But it seems that its share of the file Compass.  I'm guessing that I'm missing an inclusion, but can't find that one.

  Did not use this API but seems the enum is declared in the QCompass class itself. Try:

  m_compass-> setAxesOrientationMode (QCompass::FixedOrientation);

• Duty slot in my sensor signal connection related problem class.

  I fanned simple class based on the NDK documentation found here - http://developer.blackberry.com/native/documentation/cascades/device_comm/sensors/

  But in my case signals do not plug on slots and returns always false. I was just wondering what I did wrong? Looks all logical.

  Here's the class:

  #include 
  #include "Sensors.h"
  
  Sensors::Sensors(QObject *parent) : QObject(parent) {
      // Create the compass sensor.
      m_CompassSensor = new QCompass(this);
      m_Accelerometer = new QAccelerometer(this);
  
      // Set the orientation mode to fixed so that sensor readings
      // aren't affected by device orientation.
      //m_CompassSensor->setAxesOrientationMode(QCompass::FixedOrientation);
  
      // If any Q_ASSERT statement(s) indicate that the slot failed
      // to connect to the signal, make sure you know exactly why this
      // has happened. This is not normal, and will cause your app
      // to stop working
      bool res = connect(m_Accelerometer,
                         SIGNAL(readingChanged()),
                         this,
                         SLOT(accelReadingChanged()));
  
      res = connect(m_CompassSensor,
                         SIGNAL(readingChanged()),
                         this,
                         SLOT(compassReadingChanged()));
      Q_ASSERT(res);
  
      // Since the variable is not used in the app, this is
      // added to avoid a compiler warning.
      Q_UNUSED(res);
  
      m_CompassSensor->start();
  }
  
  Sensors::~Sensors() {
      m_CompassSensor->stop();
  }
  
  void Sensors::compassReadingChanged()
  {
      QCompassReading *reading = m_CompassSensor->reading();
      qreal azimuth = reading->azimuth();
      qDebug() << "The azimuth is " << azimuth << " degrees.";
  }
  
  void Sensors::accelReadingChanged()
  {
      QAccelerometerReading *reading = m_Accelerometer->reading();
      qreal x = reading->x();
      qreal y = reading->y();
      qreal z = reading->z();
  
      // For debugging purposes
      qDebug() << "x acceleration: " << x;
      qDebug() << "y acceleration: " << y;
      qDebug() << "z acceleration: " << z;
  }

  Please advise!  I was fighting with this for a few days already... I bet I missed something important but s mall

  Thank you

  Hello! Q_OBJECT macro is missing from the top of the class declaration:

  class Sensors : public QObject{  Q_OBJECT
  public:
    Sensors(QObject *parent = 0);
  

  p.s. This line changes, the first could not connect will not be detected. It should probably be & =

  res = connect(m_CompassSensor,
  

• "bb.cascades.multimedia" module is not installed

  Hi, I was wondering why the only thing that seems to be able to import is bb.cascades I'm on the latest sdk

  "bb.cascades.multimedia" module is not installed

  module 'QtMobility.sensors' is not isntalled

  Thank you

  The QML preview does currently support other than extra libraries

  import bb.cascades 1.0
  

  I don't belive it will be possible to use the overview with additional libraries on the road, but so far there if I want to use the preview I just create a new empty project & test this way

• Problem running QtGui / app GraphicsView on Dev Alpha

  Hi guys,.

  I'm trying to port a Harmattan on BB10 app with little success. I obviously it changed so that "haptic" uses VibrationController and QMediaPlayer replaced by MediaPlayer. QAccelerometer I used as-is from QtMobility. Other than that, I generated a new project of Cascades in the NDK, copied the source files in the folder source (qml to assets) and followed these instructions: http://www.maemopeople.org/index.php/jaffa/2012/06/20/initial_success_in_porting_harmattan_sym

  My program is compiled, but never reaches int hand (...). This is the beginning of main.cpp:

  #include 
  #include 
  #include 
  #include "mygraphicsscene.h"
  Q_DECL_EXPORT int main(int argc, char **argv)
  {
      fprintf(stdout, "reached this\n");
      fflush(stdout);
      qDebug() << "testing debug\n";
  

  None of the above messages appears when you run the application on the Dev Alpha.

  Here is the .pro (my game using opengl in graphicsview), the Makefile and bardescriptor, if theyre all help:

  APP_NAME = testapp
  
  CONFIG += qt warn_on cascades10 mobility
  QT += core declarative opengl
  MOBILITY += sensors
  LIBS += -lbbsystem -lbbmultimedia -lbbdevice
  INCLUDEPATH += ../src ${QNX_TARGET}/usr/include/qt4/QtCore
  DEPENDPATH += ../src ${QNX_TARGET}/usr/include/qt4/QtCore
  
  include(config.pri)

  PROJECT_DIR   := $(dir $(word $(words $(MAKEFILE_LIST)),$(MAKEFILE_LIST)))

  I know it's hard to fix something like that, but maybe that someone has faced problems with graphicsview?

  Well, got running and have really no idea what I did. Let's see if I can fix the remaining bugs.

  Edit: once I got the correct libraries loaded, I think it's mistakes in qml who crashed the app.

• Using QtConnectivity for Bluetooth

  Bluetooth is QtConnectivity supposed to work? I already use Bluetooth functions (bt_spp_ *) of btapi which work very well, but I really want to use the OBEX support in QBluetoothTransferManager.

  The problem is that from the beginning, when I try to create Bluetooth RFCOMM socket it fails.

  QBluetoothSocket socket = new QBluetoothSocket(QBluetoothSocket::RfcommSocket);
  

  Error:

  c:/bbndk/target_10_2_0_339/qnx6/usr/include/qt4/QtCore/qiodevice.h: In copy constructor 'QtMobility::QBluetoothSocket::QBluetoothSocket(const QtMobility::QBluetoothSocket&)':

  c:/bbndk/target_10_2_0_339/qnx6/usr/include/qt4/QtConnectivity/qbluetoothsocket.h:60:29: error: within this context
  

  Hello

  What is your actual code? socket is not a pointer. new allocates memory and returns pointers.

  Thank you.

• try to use Qt Mobility 1.2 - How to add the correct library?

  Using the QML PositionSource which is part of Qt Mobility 1.2, but continues to receive a 'module 'QtMobility.location' is not installed. At the top of my page main.qml I have "import QtMobility.location 1.2" but don't know what to do at this point.

  Any ideas? I'm a total tower to develop so, more information the better.

  Import QtMobilitySubset.location 1.1 the BB10 Qt Mobility does contain unfortunately full.

  I want to use the class QAccelerometer and QAccelerometerReading in my application. So, what libraries to include for them.

  And where I will get the libs list to include for the use of these classes.

  Kind regards

• Event QtQuick App cannot play the sound on the playbook + other problems

  Hello

  I wore a qtquick running on BB10-based application successfully. My long-term problem, it's that my applications cannot play the .wav sounds. He used the QtMobility on symbian. I am looking for a replacement and trying to adapt with open AL example in BlackBerry Github, but hopeless.

  Here is the source code: https://gist.github.com/fe1fcbbb6753bb7ff06b

  I'm lie the audio to the qtquick with the setcontextproperty method qml file. I checked with console.log () it is called.

  I wonder that the problem between the location of the file or the method is not called.

  my sounds is located under directory

  QML/stem/sounds/from the root.

  I also find that I don't see no output from qDebug.

  I use the Qt Creator for PlayBook. I wonder if I can use the momentics?

  Thanks for help. I expect to release my app before the release of BB10

  I have my solution for this problem. I opened my .pro via momentics IDE. I clicked the right mouse in the project > set up > add libraries > check list all libs > then follow the cheats provided to change the .pro files. Simple and it works.
