Qt on BlackBerry and QNX

@portoist Would be possible to get compiled Qt4.8.4 package for QNX 6.5.0 SP1 for x86 platform? I am trying to build it and getting many missing header files errors.

Hi and welcome to devnet,

Did you already saw that Wiki article ? It might contain some additional information.

Hope it helps

I've uploaded the overlay to my server.

Hope it is not too late for you guys.

Hi and welcome to devnet,

Your question is not completely clear.

Which port are you referring to ? What IPC mechanism are you using ?

Has no one managed to sign a Qt 5.2 app on Blackberry 10 yet?

thanks for your reply !
I have pressed "update" that link to blackberry develop website !
but then I know that is notice ! I still deploy the app without that notice..! :D

Is already deprecated even when Qt is in Nokia hand but in this link http://qt-project.org/doc/qt-4.8/phonon-module.html phonon seems still to be supported in Qt4.8.Try have a look.

please give the code for login and access that store in another page my id ch.narender.reddi@gmail.com

C++ has similarities with Java. So if you are experienced with Java, it should be quite easy to learn C++.

Have no idea how to link the algorithm to the qml files.[/quote]However, your question is too vague for us to answer properly. Please give us some details of what you want to do, and what you have already tried.

You can start by reading these pages:

http://qt-project.org/doc/qt-5/qtqml-cppintegration-topic.html http://qt-project.org/doc/qt-5/qtqml-cppintegration-interactqmlfromcpp.html

A new snapshot (Qt 5.2.1) is available for BB "here":http://qt-project.org/wiki/Qt5-on-BlackBerry10

For those who need to work this job out, you can just use:
@
int idle = inhibit ? SCREEN_IDLE_MODE_KEEP_AWAKE : SCREEN_IDLE_MODE_NORMAL;

screen_set_window_property_iv((screen_window_t)myWinId, SCREEN_PROPERTY_IDLE_MODE, &idle);
@

myWinId is just a QWindow's function (inherited by QQuickWindow, QmlApplicationViewer and so on...)

I reintsalled Qt 5.1 version as well as Qt Creator 3.1, now it is compiling.
Thanks for the replies.

Bonjour et bienvenue sur devnet,

La langue officielle de ce forum est l'anglais, vous aurez plus de chance d'obtenir une réponse en reformulant votre question dans cette langue.

You don't check that your image is successfully loaded and I'd be surprised that you can access /tmp on qnx.

Any reason to use a pointer to a QImage ? It's an implicitly shared class so you should save the trouble.

Vladimir, I have attached audio clip to this already opened bug:
"here":https://bugreports.qt-project.org/browse/QTBUG-37626

There is a bug, I don't if in QtCreator or BB Qt, but when I deploy a package to a device, no one delete *.bar file instead its final size is append to the old one!
When I wasn't aware of that, my bar file was about 626mb!!!

Can you elaborate on your problems? I would like to update the wiki page.

I don't think you are supposed to use visual studio to cross-compile Qt to blackberry. Instead you should use the build tools from the blackberry SDK.

The multimedia stuff for Blackberry/QNX was as far as I know never released for Qt4.
Is there any way to use Qt5.2 on your hardware?

So if you want this to work while using Qt4, look at the native APIs. Maybe gstreamer is available on your device.
