Hi all, my personal things:
Welcome to the era of stagnation and dinosaurs. The new
"revolutioning" Qt6 will be released semi-dead. It will
be overgrowned with mold, moss and fungi in the form of
CMake. This will not be a new life, but it will be an
attempt to prolong the convulsions.

Hi guys,
I need to create a 'static' plugin for the iOS, using qmake.
A problem is that the qmake can't generate a valid XCode project file,

So, I can't use XCode to deliver my application to AppStore.

As we all can see, the CMake loses even QBS. We need to spent a tens of

Hi guys.
Does anybody tried to create and start the Android Service using Qt?
I tried this example:
* https://github.com/bbernhard/qtandroidservices_example ,
and also have read this reccomendations from KDAB:
* https://www.kdab.com/qt-android-create-android-service-using-qt/
But a service do

Hi all,
I tried to make it work from the Android service:
#include
#include
#include
#include
Q_LOGGING_CATEGORY(APP, "bug.svc")
int main(int argc, char *argv[])
{
QAndroidService::setAttribute(Qt::AA_EnableHighDpiScaling);
QAndroidService app(argc, argv);
qCDebug(APP)

Hi developers.
I want to bring up a question of possibility of addition of some base tests
for QtSerialPort. I understand that it is a complex challenge because for
this purpose is desirable existence of at least two serial ports of devices
which are connected by a Null-modem cable.
But this prob

Hi all.
In development of QtSerialPort faced an unpleasant thing - big loading
of CPU in the process of I/O.
A short results can be see here:
https://bugreports.qt-project.org/browse/QTBUG-36684
This loading very big in Linux (up to 30% on 115200 baud) even at using

Ok, thanks. I will try do it as will have a free time.

Hi.
No, as I know, this issue wasn't discussed yet in plans.
But this feature was available at the primogenitor - QSerialDevice library:
https://gitorious.org/qserialdevice/qserialdevice/source/55692a7caf58fba51f859b8e015b2bbd7d92e1b6:src/qserialdeviceenumerator/serialdeviceenumerator.h

Hi all.
I have the question concerning correct treatment of documentation and
implementation of I/O methods, e.g. for QtSerialPort.

For example, regarding to the QIODevice::write() method. Investigating of
Qt5 source codes I see two approaches in classes derived from QIODevice (I

Hi.
My question most likely belongs to the Qt developers from Digia. For
example to maintainers of a "network" subsystem.
I see that in QAbstractSocket::write() in a buffered mode is used the
"deferred" data transmission:

when, the bar() method were called after foo() (with some delay), but
when not all data ("a" and "b") was written (e.g. was in time written
only "a").
then I expected to receive one bytesWrittenSignal(4 byte)
