It is not a language issue because it prints the umlauts. I do not understand what you mean by "printing the content of this one window". It could be printing the content correctly. If you step with debug, do the variables in the debug window match the correct text? Where does "Forderungen" change into "Fxorderungen"? The placeholder is not a space. 'o' is ascii 111, 0x6F. What is the ascii code for the placeholder? Is it related to 0x6F by flipping a bit? 0x04F='O', 0x02F='/', 0x0F=Shift-In, which might be printed as a place-holder. Obquote: "More information!" - Number 5, Short Circuit.

@Sucharek said in Remove spaces the from QString: I've been trying to remove the first space from a QString variable. The quickest (short and reasonably performant) code to do just this is something like: if (word.startsWith(' ')) word.remove(0, 1); QString::simplified() does quite a bit more than "remove the first space". Up to you. If you have given up on moving a QString over to a std::string, and then back again, to do your work, that is good.

@KroMignon Thanks for reply, i don't really need another thread from the main thread, i'm just asking my self how QT manage all QTIMER when we use many of theme if they have all fast interval ! and maybe in my case if i have one thread manage to refresh data and another that refresh graphic, maybe that will let all the QT APP work well ! again thanks for your help

@J-Hilk thanks for your comment. I put that to read continuously from the buffer, but of course it is not necessary as soon as the signal/slot mechansim works.

@JohannesV oh my goodness, no its not working, because you're not running an event loop in your QThread of course slots aren't executed. QCanBusDevice has signals for void errorOccurred(QCanBusDevice::CanBusError) void framesReceived() void framesWritten(qint64 framesCount) so forcing synchronous behaviour on it to then move it to a thread to get a responsive remaining application is (far from) not ideal. It is true, that overwriting QThread::run is not necessarily wrong, in this case it is. Please revisit QThreads, do you want/need helpful links ? 😅

I finally succeeded,The code I wrote is as follows: MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); m_serialPort=new QSerialPort; m_serialPort->setPortName("COM3"); m_serialPort->open(QIODevice::ReadWrite); m_serialPort->setBaudRate(QSerialPort::Baud9600); m_serialPort->setDataBits(QSerialPort::Data8); m_serialPort->setParity(QSerialPort::NoParity); m_serialPort->setStopBits(QSerialPort::OneStop); m_serialPort->setFlowControl(QSerialPort::NoFlowControl); while(!m_serialPort->isOpen()) m_serialPort->open(QIODevice::ReadWrite); connect(m_serialPort, &QSerialPort::readyRead, this, &MainWindow::handleReadyRead); connect(&m_timer, &QTimer::timeout, this, &MainWindow::handleTimeout); m_timer.start(5000); } void MainWindow::handleReadyRead() { m_readData.append(m_serialPort->readAll()); if (!m_timer.isActive()) m_timer.start(5000); } void MainWindow::handleTimeout() { if (m_readData.isEmpty()) { qDebug()<< "m_readData is empty" <<m_readData; } else { qDebug()<< "m_readData is full" <<m_readData; QJsonDocument jsonDoc = QJsonDocument::fromJson(m_readData); QJsonObject jsonObj = jsonDoc.object(); QJsonValue jsonVal; jsonVal = jsonObj.value(QString("Bat_Temp")); QTextStream textStream(stdout); textStream << QString::number(jsonVal.toInt()) << endl; }

I think MikePelton is long gone but nevertheless I would like to thank him for his contribution. I was caught out by this today. I always use the 'INS' on the numeric pad to toggle insert/overstrike - in other editors at least - so was a bit baffled as to how to get back to insert mode. As noted by Mike, the separate INSERT key does work.

@LISP Basically declare a Qt signals: ... for a C# event, declare a Qt slots: ... for a slot, and use Qt connect() to connect instances of the signal & slot objects. This appends the connection to any existing connections on the signalling object, just like C#'s +=.

@RahibeMeryem said in Dev Setup For Windows CE: I didnt see any information (my bad) for wndows CE qt 6. Support for Windows CE was dropped in Qt 5.0. 3rd party consultants might be able to help you set up an old version of Qt 5: https://www.qt.io/blog/2013/07/30/the-state-of-wince-support-in-qt5 However, there is no way to run Qt 6 on Windows CE. Qt 6 requires a C++17 compiler, while Windows CE is only supported by Visual Studio 2008 or earlier. (Even newer versions of Qt 5 won't work, since they require C++11)

Hi, out of curiosity: I see you commented out using QTextDocument with HTML content - was QTextDocument not handling your data properly? Asking since from my experience QTextDocument handles paging much better and automatically than anything else and getting the print out is just one command.

@ghutchis said in Help debugging translation failure: Do the .qm files depend on the Qt version that generate them? Like if I generate them on Ubuntu GitHub actions, can I use them on a Mac or Windows system? No, the are usually compatible with a very wide range of Qt versions. But as I mentioned in my comment - bugs happen :-)

@IknowQT You can use QAxObject to access the activeX component of MSWord and do something with your file. There are some QAX examples out there how to work with Excel or Word files. https://doc.qt.io/qt-5/qaxobject.html

@mrjj @JoeCFD Thank you

For now, I'm just fudging it - I installed an event filter for QEvent::Enter: Not great, but it works: if (event->type() == QEvent::Enter) { QWidget* target = qobject_cast<QWidget*>(object); QEnterEvent* ee = dynamic_cast<QEnterEvent*>(event); if (target && ee) { QToolTip::showText(ee->globalPos(), target->toolTip(), target); return true; } } return false;

That repo might help you.
