• How to connect NotificationDialog finished() signal to a process without a head?

  I tried to get a process in the background to handle the signal in my application without head (because NotificationDialogs are now supported for background process).

  However, whenever I try to connect the signal to a slot, I get the following error:

  QObject::connect: Cannot connect (null): Finish (bb:latform::NotificationResult:Type) at MessageProcessor::dialogFinished (bb:latform::NotificationResult:Type)

  
  
  cpp file:
  
  QObject::connect(pNotificationDialog,SIGNAL(finished(bb::platform::NotificationResult::Type)), this,SLOT(dialogFinished(bb::platform::NotificationResult::Type))); //(for this line I also get the warning below)
  //MessageProcessor::dialogFinished(bb::platform::NotificationResult::Type) has not been //tagged as a Qt member; make sure all parameter types are fully qualified
  
  hpp file:
  
  #include 
  
  class MessageProcessor  : public QObject{
  Q_OBJECT
  
  public slots:
  void dialogFinished(bb::platform::NotificationResult::Type value);
  
  };
  
  Is finished() supported for headless apps?
  

  You are probably not initializing pNotificationDialog

  pNotificationDialog = new bb::platform::NotificationDialog(this);
  

• InvokeTargetReply finished() signal not shooting?

  I have a problem like that in the original post in this thread:

  http://supportforums.BlackBerry.com/T5/native-development/invokation-framework-slot-for-signal-Finis...

  The poster of thread apparently solved their problem for their use case by invoking a card instead of an application, but this solution is not suitable for my use case - I simply invoke a basic application, by using a reusable code taken right out of BlackBerry tutorials, and apparently, so the launch of base app, finished() signal is not emitted.  This seems so basic that I expect others have run across it, and there is a subtle touch that is not sufficiently covered in the tutorials.

  Code:

  void ApplicationUI::launchCoreApp() {
  
      qDebug() << "The launchCoreApp() method was called";
  
      bb::system::InvokeManager invokemanager;
      bb::system::InvokeRequest request;
  
      request.setAction("bb.action.OPEN");
      request.setTarget("sys.browser");
      request.setUri("http://www.blackberry.com");
  
      bb::system::InvokeTargetReply *reply = invokemanager.invoke(request);
  
      if(reply) {
          if(reply->isFinished()) {
              qDebug() << "In launchCoreApp(), reply finished before we could connect signal to handler slot";
          } else {
              qDebug() << "In launchCoreApp(), connecting reply finished signal to handler slot";
              bool ok = connect(reply, SIGNAL(finished()), this, SLOT(onInvokeTargetFinished()));
              Q_ASSERT(ok);
          }
  
      }
  
  }
  
  void ApplicationUI::onInvokeTargetFinished() {
      qDebug() << "The onInvokeTargetFinished() slot was reached";
  }
  

  Note that this is just a test code and I didn't intend to instantiate a new InvokeManager on each call to the launchCoreApp() function - I just need to see how things work.

  So, when I run the above, launches the browser and goes to the provided URI, my debug console told me that the value of reply-> isFinished() is false, so my code takes the branch to connect the finished() signal to the onInvokeTargetFinished() slot.

  However, the slot is apparently never called, not the browser launch and not when I close the browser.

  It's reusable code light directly from the tutorials and docs, but it doesn't seem to work as announced.

  When subtle I'm missing?

  Where in the lifecycle of the invocation request response is the finished() signal is supposed to be issued?  The reference docs are very clear on this - they just say it is issued when the response message is "received", whatever that means (I understand that it is a future model, I'm not clear which is received in the life cycle integer invocation response).

  I am compiling against level API 10.2 BTW.

  I work, the only thing needed is to define the parent for the response, otherwise it will be deleted at the end of the function where it is created.

      bb::system::InvokeTargetReply *reply = invokemanager.invoke(request);
      reply->setParent(this);
  

  The parent is responsible to remove the answer, so be sure to remove it in your home.

  void ApplicationUI::onInvokeTargetFinished() {
      qDebug() << "The onInvokeTargetFinished() slot was reached";
      bb::system::InvokeTargetReply *reply = qobject_cast(sender());
      reply->deleteLater();
  }
  

• How to connect the slot button Cascades

  I am new to waterfalls and QML and yesterday I tried to port native QtWidget app to waterfalls, but it does not. The problem is, I add some buttons to the container in QML main file and coded my custom slot function which should be executed when the user click some button. But I don't know how to connect the clicked() signal to my function from the custom location.

  When using

  Connect (CloseButton, signal(Button::clicked()),this,slot(on_closeButton_clicked()));) or connect (exitButton, SIGNAL (clicked ()), this, SLOT (on_exitButton_clicked ())); I get error "unable to connect SIGNAL (null) to SLOT (on_closeButton_clicked ()) ' on all the buttons.

  Here is my code in app.cpp

  App::App()
  {
      QmlDocument *qml = QmlDocument::create("main.qml");
      qml->setContextProperty("cs", this);
  
      AbstractPane *root = qml->createRootNode();
      Application::setScene(root);
      textHolder = root->findChild("textHolder");
      openButton = root->findChild("openButton");
      saveButton = root->findChild("saveButton");
      saveAsButton = root->findChild("saveAsButton");
      closeButton = root->findChild("closeButton");
      exitButton = root->findChild("exitButton");
  
      connect(openButton,SIGNAL(Button::clicked()),this,SLOT(on_openButton_clicked()));
      connect(saveButton,SIGNAL(Button::clicked()),this,SLOT(on_saveButton_clicked()));
      connect(saveAsButton,SIGNAL(Button::clicked()),this,SLOT(on_saveAsButton_clicked()));
      connect(closeButton,SIGNAL(Button::clicked()),this,SLOT(on_closeButton_clicked()));
      connect(exitButton,SIGNAL(clicked()),this,SLOT(on_exitButton_clicked()));
  }
  
  //one slot function
  
  void App::on_closeButton_clicked()
  {
  //ui->textEdit->clear();
      textHolder->resetText();
  //if(file.open(QIODevice::ReadOnly | QIODevice::Text)){
      file.close();
      fileName.clear();

• How to connect signals Ni SCB - 264 X

  We bought PXI switch 2532 with TB-2641. We also have
  bought burst of SCB-264 X. I have a question about the signal
  connections. SCB-264 X is supplied with only the connections of signals (C0, C1
  etc). But what of the ground for each signal. How to connect the
  mass of each signal signal.

  Thank you

  Kitenge

  Hi Kitenge,

  The connection TB-2641 block creates a configuration of matrix 8 x 64 1-wire for the NI PXI-2532.

  1 - wire configurations are typically used for single-ended signals: when he shared there or return a common ground.  In these configurations, the constant signal line is usually wired externally (not changed).

  If a part of your application requires switching differential signals (2-wire), you can use an additional column for tracking on the ground of each signal.  Similarly, additional lines are required.

  If all your application passes only signals from 2 threads, then the TB-2643 or TB-2644 may be more appropriate than the TB-2641.

  The connection TB-2643 block creates a matrix 4 x 64 2 wires.

  The connection TB-2644 block creates a 8 x 32 2-wire matrix.

  I hope this helps!

• How to speed up my signal for Auntie plu photon strength?

  Original title: problem with Auntie photon more net connection

  How to speed up my signal for Auntie plu photon strength? My net is too slow & very dull.

  Hi shilpadarbar,

  Thank you for writing to Microsoft Communities. From your problem description, I understand that the internet connection is slow. Before you start the troubleshooting steps, I need the required information:

  ·         You get the error message?

  ·         Did you do changes on the computer before the show?

  Follow these methods to the problem of slow internet connectivity.

  Method 1: Follow these steps:

  Step 1: Start the computer in safe mode with network and check if the problem persists.

  Step 2: If the problem does not persist in safe mode with networking, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

  Note: After completing the steps in the clean boot troubleshooting, follow the section How to configure Windows to use a Normal startup state from the link to start the computer to a Normal startupmode.

  After the clean boot used to resolve the problem, you can follow these steps to configure Windows XP to start normally.

  (a) click Start, run.

  (b) type msconfigand click OK.

  (c) the System Configuration Utility dialog box appears.

  (d) click the general tab, click Normal startup - load all services and device drivers and then click OK.

• finished() signal for invoke() on phone app)

  I use bb::system:InvokeManager to start a call using action 'bb.action.DIAL '.

  response of bb::system:InvokeTargetReply * const = invokeMgr.invoke (invokeRequest);

  Invoke() will return an InvokeTargetReply. This response will signal finished(). I use

  Boolean result = QObject::connect (response, SIGNAL (finished (()), this, SLOT (onInvokeResult ()));

  to connect the signal with the slot. However, my CRACK onInvokeResult() is never called. Why is this?

  (1) something wrong with my application?

  (2) signal/slot mechanism only works inside your own application. If this approach can be used when calling invoke() to an external application. Signal/slot isn't an IPC mechanism.

  Documentation says errorType and errorCode is valid after the finished() signal.

  BB::System:InvokeTargetReply * response = qobject_cast(sender());
  BB::System:InvokeReplyError:type errorType = response-> error();
  int errorCode = response-> errorCode();

  If the signal/slot mechanism cannot be used internally within your own application, how can you know if the invoke() on an external application would be successful?

  I wasn't looking to extract the right aways errorType and errorCode after calling invoke()... maybe that can already tell me the result?

  BR, René

  Thanks for sharing this code. My code is almost the same. And I solved the problem. My code now looks like this:

  BB::System:InvokeManager invokeMgr;
  response of BB::System:InvokeTargetReply * = invokeMgr.invoke (invokeRequest);
  If (answer)
  {
  Set the parent for this 'response' otherwise 'response' will be deleted at the end of this function.
  response-> setParent (this);
  Boolean result = QObject::connect (response, SIGNAL (finished (()), this, SLOT (onInvokeResult ()));
  ...

  void controller:nInvokeResult()
  {
  Get the response from the sender object
  BB::System:InvokeTargetReply * response = qobject_cast(sender());
  BB::System:InvokeReplyError:type errorType = response-> error();
  int errorCode = response-> errorCode();

  response-> deleteLater();
  }

  It turns out that it is absolutely essential to add a parent to the response using the line "answer-> setParent (this);" in order to receive the signal finished(). If this line is commented out, then the slot is more will be called.

  You may not use a local variable for the answer, but a member of the class. That also seems to work.

  Thanks for the help!

  You can use two cables to connect your laptop to the TV. It s according to the interfaces on the laptop and the TV, but in both cases, it of the same:
  Connect the cable to the laptop and TV, turn on your TV and select the right channel, then turn on your laptop. After the clean boot procedure, you can switch between monitors with FN + F5.

  If you use S-Video cable make sure you are using the coding system good TV, e.g. PAL or NTSC.

  How to connect 2 monitors to a HPE-210y PC? I have 2 monitors HP2010i . Behind the PC, there is a VGA - DVI input and an HDMI input. I have connected a monitor to the PC with a VGA - DVI adapter. I saw a VGA input which was covered with a plastic plate "DO NOT REMOVE" black screwed attached. I removed the plate and the second monitor connected.

  The second monitor keeps saying "No Signal" and goes to sleep. I tried the monitor plugs around switching, but I keep getting the same results. Only the monitor connected to the VGA - DVI input works.

  How can I connect two monitors to this PC?

  Thank you

  You must also use the HDMI port. To do this, you need an adapter DVI HDMI and a DVI cable.

  The other VGA port has been covered for a reason, to keep you to try what you did. When a graphics card is used, the video port of the motherboard is disabled.

  See you soon,.

• How to connect his computer without HDM to Toshiba 40LV933G

  Hello

  I have a Dimension 5150 desctop computer and want to connect to my Toshiba 40LV933G TV.

  The computer has no HDMI output.
  I am able to get the help of VGA video cables.

  But I'm not able to get sound.
  I tried Mini RCA cable but still no sound. (cables are fine, I checked it on the installer of my friend).

  Mini is it to RCA installation cable supported in the 40LV933G of Toshiba?

  Any ideas?

  Thanks in advance.

  Hello

  First, he must know that VGA port (on your computer) does not transmit the audio signal. The VGA (RGB) port supports only the video signal.
  So if you wish to receive the sound on your TV, you must connect an additional audio cable Y from a port like jack SPDIF or headphones to your computer audio output to the TV audio IN (L, R) port.

  Find a TV manual where you can check how to connect an external equipment:

  Hey guys please help

  I can't connect my PS3 to the Qosmio G30-201. I tried with the HDMI cable but do not know how to connect.

  Can any 1 advise me how to connect?

  Thanks in advance

  > I use the hdmi cable to receive brillaint image quality and I tried with the Qosmio player with hdmi cable but couldn't make any image what so ever.

  Dear TV, have you read what other people write here. To send the video signal to the laptop, you use VIDEO IN port. HDMI port on your laptop is probably VIDEO OUT port. Also, it cannot work.
  Read it please user manuals to see which ports are video in ports. This port allows to transfer the video signal in your laptop.

• Q. G20-117: how to connect to a digital antenna (DVB - T decoder)

  Hi everyone, hope you can help me with some tips and tricks to connect the Qosmio G20-117 computer to a digital antenna (DVD-T set-top box) from Samsung.

  The problem is that the connection with the coaxial cable is really very bad, so I'm wondering how to connect this receiver with a cable SCART original...

  Thank you!

  Erik

  Hello

  As far as I know original SCART cable can be used just for the signal and not the signals in. In my opinion, you must connect the external device to your Qosmio use composite cable. Check it with Qosmio player. Scan of the channels and a single channel should be based.

  Good luck!

• How to connect satellite Pro L40-15 has to my TV?

  Hello

  I would use the laptop connected to my TV to watch movies. Can be connected using the TV as a monitor and what kind of cable would you use?

  Thank you
  Malc

  To connect the laptop to the TV is very easy. If you look at the user s manuals document you will find exact explanation how proceed.

  If I remember well your laptop should have S-Video output and video signal transfer port, you must use S-video cable. I hope your TV's S-Video IN port. If this isn't the case, you can use different cards.

  Please check this thread and read carefully reading written by Miro. He explained very detailed how to connect the laptop to the TV.

  If you have any other questions please post again.

  How can I connect a satellite receiver to my Qosmio g30-188? I need to connect the AV signal (SCART) on the receiver to the laptop.
  can someone help me?

  Thanks in advance!

  Hello

  I didn't test it with cable SCART, but I presume that you need adapter SCART to connect to your satellite receiver. Here is the image what it looks like.

  On this map, you can connect S-video cable to transfer the picture to your Qosmio. You will find on the right side for laptop S-video PORT. For sound, you can use the audio cable (red/white) with proper adapter

  As I said I n t test it until now. In any case please check manuals s user document. Maybe, you can find some useful information.
