Mobile and Embedded

Thanks for the clue bat, I know it's not a real file, but I wasn't thinking of the implications of that. I started out using a while loop with file.atEnd() as the terminal condition, but that won't work as you pointed out. I'll just have to read til I get a no more data return from readline() . Again, Thanks.

That kind of thing happens :) Happy coding !

@jalomic said: @a.toraby said: JavaVM * _jvm = 0; JNIEnv* _jniENV; qDebug() << "Attaching current thread"; _jvm->AttachCurrentThread(&_jniENV,NULL); As i see here _jvm - is a null pointer.. and you call method from null pointer Yes you are right. I solved it by using a QAndroidJniEnvironment: Here is the working code: class HelloWorldTask : public QRunnable { QAndroidJniEnvironment * _env; void run() { JNIEnv * jniEnv; JavaVM * jvm = _env->javaVM(); qDebug() << "Getting jni environment"; jvm->GetEnv(reinterpret_cast<void**>(&_env), JNI_VERSION_1_6); qDebug() << "Attaching current thread"; jvm->AttachCurrentThread(&jniEnv,NULL); qDebug() << "Creating byte array" ; jbyteArray jBuffer = jniEnv->NewByteArray(10); qDebug() << "byte array created" ; jvm->DetachCurrentThread(); } public: void setPointer(QAndroidJniEnvironment * p){ _env = p; } }; int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); HelloWorldTask * hello = new HelloWorldTask(); QAndroidJniEnvironment * env; hello->setPointer(env); // QThreadPool takes ownership and deletes 'hello' automatically QThreadPool::globalInstance()->start(hello); return a.exec(); }

Thansk a lot. I don't know how many times I saw this "create templates" button and told myself "it can't be this one". So stupid! A.B.

(But who knows what will happen when Windows 10 will be released..)

It think I may have understood your problem. You didn't put your separated widgets in a layout ?

Thank you, everything is ok now :-D

Ok, solved it my self. The stylesheet syntax was wrong. Actually i have little problems to figure out the mechanisms. This works: slider1->setGeometry(50, 370, 900, 140); slider1->setStyleSheet("QSlider::groove:horizontal{border: 20px solid #800040; height: 10px; background: red; margin: 90px 0} QSlider::handle:horizontal{background-color: green; border: 3px solid blue; width: 140px; border-radius: 3px; margin: -65px}");

Hi and welcome to devnet, You should use LIBS += -lopencv_core \ -lopencv_XXX \ -lall_need_libraries here it's a lowercase L, uppercase L is more adding additional search paths for the linker and lowercase L is for telling the linker which lib it should use. From your errors in looks like you are not linking to the genicam libraries

Nice ! @McLion Schöni Platz ! :)

Hi, AFAIK, there's nothing yet but you can try asking on the android-development mailing list.

Thanks for the tip!

Hello garyeholmes, How did your app turn out? I am also using QProcess to call a series of commands (namely, iw, iwlist, wpa_passphrase, wpa_supplicant, and udhcpc). I do have a different way of passing arguments to command lines though, for example: QStringList args; args << ui ->ifaceLine->text(); args << "scan"; scanProcess.setStandardOutputProcess(&grepProcess); scanProcess.start("iwlist", args); grepProcess.start("grep", QStringList() << "ESSID"); grepProcess.waitForFinished(); Whenever I call udhcpc, I get stuck at "Sending discover". I can't get past this message, so any info you learned can really help a long way. Thanks

s.frings74, thank you for sharing your project C++ code with the community. Not everyone who works with Qt mobile dev wants to jump on the Qt Quick bandwagon.
