• dynamically load the Options in a drop-down list in C++

  Hey guys,.

  I'm trying to dynamically load items Option in a drop-down list by using C++.  I have a function in my class of WorkManager file that does the trick:

  QStringList WorkManager::getListOfItems() {
      int i = 0;
      QStringList taskNames;  // used for debugging mainly, so i can print the list out to debug
      QList  myObjects = m_model->toListOfObjects();
      DropDown * dpList = bb::cascades::Application::instance()->scene()->findChild("scriptListDropDown");
      if (dpList != 0 ) {
          dpList->setSelectedOption(0);
          dpList->removeAll();
          for (i = 0; i < myObjects.size(); i++) {
              Task * myTask = (Task *) myObjects[i];
              taskNames.append(myTask->taskName());
              dpList->add(Option::create().text(myTask->taskName()).value(myTask->command()));
  //          delete myTask;  // do I need to delete the task object?
          }
  //      qDebug() << "WorkManager::getLIstOfItems(), ---> list of tasks is : " << taskNames;
          return taskNames;
      } else  {
          qDebug() << "WorkManager::getListOfItems(), ---> dpList was 0";
          return taskNames;  // empty list
      }
  }
  

  I also found this thread:http://supportforums.blackberry.com/t5/Native-Development/Adding-options-to-a-DropDown-from-c/m-p/21... that helped me get the filled drop-down list when the application starts.

  However, I need to re - fill list from time to time, when the list (a GroupDataModel) changes.  calling the function above a second time anywhere in my application appears to hang the application immediately.

  I think / thought it might have something to do with the slot for the onSelectedValueChanged, but I can't understand it.

  It seems down right when I do dpList-> removeAll().

  I also can't seem to find the right place to call this function to an object of type in my class.  I think it's because the drop-down list is not ready yet as the dpList * is always 0 unless what I call after the line:

  app->setScene(root);
  

  in the applicationui.cpp file.  Calling it works on start-up, but trying to update the list later (by removeAll() and recreate) causes the app crashing.

  is there a better way to do it?  .. and make it safer?  I can't understand how to do this.

  Thank you!

  First, drop the:

  dpList->setSelectedOption(0);
  

  Not only if it is not necessary, but it will explode your application if the function is called when there is already no options in the menu dropdown.

  Also, do NOT delete the task, because it is still owned by the datamodel. I also see that you use type casting C, which just blindly accepts your cast, even if it's a mistake. Instead, if you know for sure what kind it will be this way instead:

  Task* myTask = static_cast(myObjects[i]);
  

  If you are not sure if the type you are casting the is the type you need, use the dynamic_cast instead:

  Task* myTask = dynamic_cast(myObjects[i]);
  

  The advantage of this more static_cast , is that if you try to perform a type cast is not compatible, then myTask will be set to NULL.

  Alternatively, Qt offers a replacement for dynamic_cast which works on platforms where is not regular C++ casts.

  Task* myTask = qobject_cast(myObjects[i]);
  

  It is functionally equivalent to dynamic_cast, but as I said, it works on all platforms that Qt exists, whereas dynamic_cast cannot.

  Once you did get back to us.

• How to load the site down?

  Hi guys!

  Does anyone know how I could get the loading from the bottom instead of top page? I foresee a "backside" parallax page where the user would scroll upward from the bottom instead of from the top down.

  THX

  There are a lot of ways, jQ, js, etc to anchor tags.

  You can use the redirect on the charge, which would be to insert an html tag on the bottom of the page, and then for the body, include.

  Thank you

• HP deskjet 6122 could not load the driver on the CD, he says is no longer supported

  Original title: printer HP Printer driver

  I have an old printer of HP deskjet 6122.  It works very well.

  However, when I plugged in a new desktop computer, I could not load the driver for the CD.  He said that it is more compatible.

  Later, I learned that the driver for HP 990 will work as a substitute.

  When I go to the HP site, there is no help as it attempts to identify my printer before you download the driver.  It identifies my printer 6122 as obsolete and will not load the driver down 6122 or 990.

  Where can I go to download the HP 990 regardless of HP driver?

  It's the HP 990c driver you want?

  If so have you tried selecting the update of Windows while in the Add Printer Wizard?

  It will take more than 5 minutes to get an updated list of printers and the 990c is.

• Satellite A300-1EC cannot load the OS and restart just /shuts down

  Can you help me with my problem of A300 PSAG0Elaptop.

  This is the case:
  before that I can still use my laptop normally without plugging the power cord but when plug the source ca the unit restarts all of a sudden. I charge the battery only when the unit is off. And now the worst case gets when I installed the recovery disk hoping would solve the problem. I can no longer load the operating system; It's just loading then it does not load and suddenly shuts down and sometimes simply frozen. I have not tried the safe mode, mode ahci, system recovery, system repair, and stil no chance.
  I brought this already at the center of ASP service and they demanded almost 1 unit brand new laptop for repair of my laptop is not advisable to send them to repair.
  I doubt that my system bios is not compatible with my vista Home premium OS, or perhaps my wife update of the bios that is not compatible in windows update. My current bios I checked is 1.4

  Given that I have no option instead of junking my laptop, I want to update or back to the original settings of the bios that can help to repair my device.
  Can you help me on how to update or revert to the original my system bios? As I can't access the windows can you teach me step by step using the usb port of my camera on system bios update? Or do you have any suggestions?

  Need help bad
  Here are the specs of my unit

  Hey Buddy,

  First of all, the BIOS can only be updated Windows System. There is no other version that you can download on the site Web of Toshiba.

  But I doubt that this problem is caused by the BIOS. It s I knew not that it is possible to change certain values which make impossible Windows installation. With other words BIOS is secure and with all the settings, it should be possible to install Windows.
  An alternative you can press F9 in BIOS to load the default settings. That would be the best option.

  But according to your assignment, if Windows installation of recovery disc doesn t work and you are not able to charge the battery while the laptop is turned on it seems to be a hardware malfunction because seriously it has nothing to do with the software.

  So either come you into contact with the ASP to get the repaired device or you can repair yourself with original spare parts with parts ASP or second-hand on eBay or similar platforms.
  Of course, you can buy a new laptop: in case the motherboard would be defective because the motherboard is very expensive spare part, it would be the best choice in my opinion.

  I hope this helps!

• Once I refreshed, when I go to pull down to a previous visit, it loads the address bar, but will not go on the site.

  Everything was going well until I refreshed Firefox. Since then, the address bar does not work.

• The output on my Macbook Pro is not giving me the drop-down list, & happens either in the port of the helmet or digital port and neither one is what I need. I tried turning off the computer and hold "Shift"' Control', 'Option' with the power-o ".

  The output on the sound output box has no drop downs. The audio output suddenly disappeared and when I went to the 'exit' sound in 'sound preferences' the only thing that would show was the headphones.  After that I tried a couple of things suggest that 'Helping Apple', sometimes in digital form & everything that happens you can't change for something else.  Things I've tried suggested by Apple press help were the "Shift control option buttons & button / stop at the same time."  or press the Option, the command, the P & R key as soon as possible after you have pressed the button On.  Hold down until after the second gong during a manoeuvre.   This did cause the digital option, but none of these 2 is the one I need.  Help

  Perhaps, it would be useful to know what that is exactly the one you need. Are get you an external speaker output or anything like that. Also, it would be useful to know the operating system you are using.

• Old laptop has only WEP in the drop-down list of options wifi, I need to do using WPA2-PSK. How to do it?

  It's an old Toshiba laptop Satellite Pro M10 with an Intel PRO/wireless LAN 2100 3B Mini PCI adapt (whatever that means!), I did all the updates of Windows, but when I try and establish a connection wifi encryption options of data only from the drop-down are 'disabled' and 'WEP '.

  I checked on the Toshiba site and downloaded the latest wifi and internet updates, I even tried Intel Update site, but they have nothing appropriate (something to do with Toshiba, make changes to drivers for Intel do not offer updates).

  It connects to the internet without problem if I use a cable, but it's not really practical, wifi would be much better.

  Can anyone suggest something to make my laptop use/recognize the WPA2-PSK?

  Thank you very much

  I talked to Toshiba, very nice chap called Daniel spent 30 minutes on the phone and found a very old and apparently obscure update for me to download. Once this has been done the phone was able to connect to the router WPA2-PSK using WEP. Not too sure exactly what the update does but at least it will now connect to modern wi - fi, even if it is only at 11 Mbit / s. apparently, it's as much as the material can handle!
