@Remya How your are installed QT virtual keyboard(English). I want to install on Windows as I am using Qt designer and PyQt5.

Hello all, I think I found the solution I have found another driver for Cassandra on below link: https://github.com/datastax/cpp-driver/tree/master I tried to use it and it is is working with QT

Are you sure that the correct uic version is used ?

@SGaist I have resolved the problem by: following the guide stated in the start slot of QSensor documentation

@Padlock right !

Thanks a lot @mrdebug, that's what I ended up with.

Finally I found a solution. QGuiApplication::allWindows() Is the trick. Code like this solved my problem. for(QWindow * w: QGuiApplication::allWindows()) { if(std::strcmp(w->metaObject()->className(), "QtVirtualKeyboard::InputView") == 0){ if(QObject *keyboard = w->findChild<QObject *>("keyboard")){ QRect r = w->geometry(); r.moveTop(keyboard->property("y").toDouble()); w->setMask(r); return; } } }

Handle keys events in qml. https://doc.qt.io/qt-5/qml-qtquick-keys.html

Thank you! It was useful to me

I have found the solution. First of all: The error message EGL library doesn't support emulator extensions does not come from the eglfs_kms plugin itself, but from the emulator plugin eglfs_emu which is used as a fallback, since the original plugin could not be loaded. So why could eglfs_kms not be loaded in the first place? The answer is that the library, resp. symlink libQt5EglFsKmsSupport.so.5 had not been deployed on my target device; therefore, loading the eglfs_kms plugin failed. Deploying the library with the appropriate symlink fixed the problem, i.e. the filesystem should look like this: ~ # ls -l /usr/lib/libQt5EglFsKmsSupport.so.5* lrwxrwxrwx ... /usr/lib/libQt5EglFsKmsSupport.so.5 -> libQt5EglFsKmsSupport.so.5.12.8 -rwxr-xr-x ... /usr/lib/libQt5EglFsKmsSupport.so.5.12.8 I found this out by doing an strace on one of Qt's example applications: export QT_QPA_EGLFS_INTEGRATION=eglfs_kms strace /usr/lib/qt5/examples/widgets/tutorials/notepad/notepad 2>&1 | tee log.txt and then greping for failed open-statements. @Pablo-J-Rogina Thanks for your time!

Hi, thanks a lot. That looks exactly for what i m searching. I will give it a try.

Thanks. i always learn a lot from you QT chompion~ :) i will be back later with some other REST API problems........

Hi, Qt has nothing to do with mesh WiFi protocol. Here you have a list for mesh related reference that might be of interest.

After set cmake Initial CMake parameters is "-DANDROID_STL:STRING=c++_static", compile ok

The problem is likely the NDK version, which is optimal for Qt 5.12.3, but likely not compatible with 5.15
