Qt on BlackBerry and QNX

[quote author="Rondog" date="1385603145"]It sounds like you don't have the variable QNX_TARGET set properly. On my system it is set like this: QNX_TARGET="/Users/ron/bbndk-2.1.0/target/qnx6" ... If you do have it set then maybe the location is wrong?[/quote] Thank you for answer. QNX_TARGET variable in my QNX system sets to /usr/qnx650/target/qnx6 I suggest, that error in file /qt-everywhere-opensource-src-5.1.1/qtbase/mkspecs/common/qcc-base-qnx.conf @... QNX_DIR = $$(QNX_TARGET) isEmpty(QNX_DIR) { error("QNX_TARGET environment variable not set") } QMAKE_INCDIR = $${QNX_DIR}/usr/include $${QNX_DIR}/usr/include/freetype2 QMAKE_LIBDIR = $${QNX_DIR}/$${QNX_CPUDIR}/lib $${QNX_DIR}/$${QNX_CPUDIR}/usr/lib QMAKE_LFLAGS += -Wl,-rpath-link,$${QNX_DIR}/$${QNX_CPUDIR}/lib -Wl,-rpath-link,$${QNX_DIR}/$${QNX_CPUDIR}/usr/lib ...@ Result of this script qcc -Vgcc_ntox86 -o "/qt-src-5.1.1/qtbase/bin/qmake" project.o ... -lang-c++ -Wl,-rpath-link,$(QNX_TARGET)/x86/lib -Wl,-rpath-link,$(QNX_TARGET)/x86/usr/lib looks like a wrong. I suppose, that instead QNX_TARGET variable must be value of QNX_TARGET. Also unknown -rpath-link parameter present. May be typo error? All my attempts to correct script were unsuccessful

Thanks for replying Thomas! "These instructions":http://qt-project.org/wiki/Qt-Creator-with-BlackBerry-10 are pretty recent, updated last monday according to wiki. They cover Qt Creator 3.0 and API level 10.2.0.1155, so they should be fairly up-to-date. I know Momentics itself isn't used, but as far as I can tell the QNX plugin does use the toolchain and precompiled Qt libs from BB. Or not? My menus and settings don't include any BlackBerry stuff. That's the problem.

You will need the includes and the libxxx.a file. In the pro file: LIBS += %path%libXXX.a INCLUDEPATH += %PATHTOTHELIBHEADERS% That should do. Maybe you also could set this up over Momentics, but good luck with that...

So I got a working solution. First the bad part: that isn't possible over the IDE. You will need to add a new buildtarget. First in the pro file, myconfig{ DEFINES += MYDEFINE } will add the define in this configuration. Next thing is to copy the make targets from mk/cs-base.mk (in target/.../include folder). for example: Device-Debug-myconfig:arm/Makefile-myconfig //then copypaste of Device-Debug rule arm/Makefile-myconfig:/* copy paste arm/Makefile rule*/ add CONFIG+=myconfig ... Now, you are setup, last thing is to change the make build target of you build configuration to the new Device-Debug-myconfig rule. Repeat for every build configuration and needed make-target. Thanks to Elena Laskavaia for pointing me at this solution :)

I know that and I've also asked on BB forum...no one knows that!

Add two spaces between the words you want on separate lines. <name>Part1 Part2</name>

So it is not possible to draw text using the Momentics??? That'd be bummer I think my stuff is almost good to go if I could just draw some text on my graphics. I'm drawing on QImage via QPainter it was looking so good until I tried to add some Text, BB10 documentation is pretty poor. SIGSEGV when I tried to call drawText

Cascades is BlackBerry UI toolkit built on Qt Quick. Qt Quick have only primitives like Rectangle, MouseArea, Gradient and etc. Combining those Cascades gives you various buttons, menus and etc. You can still use BB10 APIs from your non-Cascades app.

Hi Fabian, So sad, but seems to be true. Only Cascades apps has the full featured BB10 keyboard. :|

Hi Rondog, thanks for your help, your source code is very interesting, I will try to implement it. My project uses MainWidget, the original version of the project (Symbian) used MainWindow. I tell you that a week ago I heard of Qt for BlackBerry, I want to port my app. The most important functions of the app are: Send and receive SMS automatically (Not ported) Making and accepting requests http automatically (ported) Sqlite data base management (ported) The quality of the graphical interface is secondary. Apparently Qt Creator has limitations, I will try to implement the most important functions (Send and receive SMS automatically). If I solve the problem, I will continue with the GUI, but if I have problems I'll have to start using BlackBerry Native SDK. Thank you very much.

Coldpeace, I did what you said (cleaned the projects, set the right kit). It works (only with new proyects). My proyect (symbian) don't works. Now I will copy-paste the source code, look for the error. Thank you very much to all.

It should be possible to utilize the nokia plugin. If you are using Qt5, there is an OpenStreet maps one afaik. The position plugin for Blackberry is not yet upstream in Qt5 but will probably be available soon.

Hi, are you using QtGui or Cascades and which Qt version? I think there are several ways to do that. Did you already look into the qnx platform plugin? The touch events are sent with QWindowSystemInterface::handleTouchEvent(w, m_touchDevice, pointList); So you could hack it into the platformplugin somehow. Another possibility would be to inject a bps screen touch event into the qt event loop. You might want to have a look at: QQnxBpsEventFilter::nativeEventFilter(const QByteArray &eventType, void *message, long *result) and: http://developer.blackberry.com/native/reference/bb10/screen_libref/topic/function_types.html

I was referring to BB10's Cascades which supposedly is different from the Qt Quick Controls (aka. Qt Desktop Components). I have to admit that I only ever tried to run demo apps shipped with the SDK on BB10 to test the creator integration, so I may be wrong.

Txs Bomb3rman I'll get it.
