@SGaist Thank you, that's what I needed.

@user4592357 Usually a class which emits signals should not know anything about classes which connects to its signals. I suggest you provide an interface in your model to get the actions, then your main window can get these actions and connect to them - your model does not have to care about classes connecting to it.

I found a solution myself. When drawing the image I can get the current screen and its device pixel ratio. This is the current scaling factor Windows is using. With this factor I can scale the image to the current size. regards Oliver

@JoeCFD said in problem in sending a json file to url: void ClassName::postFinished() { std::cout << " error " << qPrintable( m_reply->errorString() ) << std::endl; } the output in slot postFinished() Unknown error This was only an example to explain how-to get in touch when request is done! I just rewrite your code to made it work. A more logical process would be: connect(reply, &QNetworkReply::finished, this, [reply]() { if (reply->error() == QNetworkReply::NoError) { QByteArray data = reply->readAll(); QDebug() << "Success:" << data; } else qDebug() << "Failure: " << qPrintable( reply->errorString() ); });

If you just need something like outerHTML in javascript, you can use QDomNode::save like: QString output; QTextStream stream(&output); node.save(stream, 0);

@tadamo You need to get the exit code AFTER the process finished. Asynchronous (non-blocking) way: QProcess *myProcess = new QProcess(this); connect(myProcess, QOverload<int, QProcess::ExitStatus>::of(&QProcess::finished), this, [=](int exitCode, QProcess::ExitStatus exitStatus){ //use exitCode here directly }); myProcess->start(program, arguments); Synchronous (blocking) way: myProcess->start(program, arguments); myProcess->waitForFinished(); int res = myProcess->exitCode(); Note: you may also need to handle FailedToStart error when "start" or timeout when "waitForFinished"

An example set of properties (some are Windows specific) to set in the .pro file can look like this: QMAKE_TARGET_DESCRIPTION = This is a description of my product QMAKE_TARGET_PRODUCT = SomeProduct QMAKE_TARGET_COMPANY = SomeCompany QMAKE_TARGET_COPYRIGHT = Me! VERSION = 1.2.3.4 For all possible options see qmake variables reference.

Sorry but it is not really any clearer.

That's just a wild guess but you might be able to use Selenium as usual if your application is built for WASM. Otherwise, AFAIK, the reference tool is Squish.

@SGaist Hi. Ok, I changed eventFilter() a little bit: bool MainWindow::eventFilter(QObject *obj, QEvent *event) { if (obj == ui->textEdit) { if (event->type() == QEvent::KeyPress) { QKeyEvent *keyEvent = static_cast<QKeyEvent*>(event); qDebug() << "Ate key press " << keyEvent->text(); } } return QMainWindow::eventFilter(obj, event); } and now it works. Thanks!

Hi, One thing worth trying is the Qt Graphics View Framework. You might be able to apply the transforms you want on the item but I can't guarantee it.

Hi, This is a user forum, there's nothing we can do about that here. If you want to talk design decisions, you should bring this to the interest mailing list.

@jsulm said in QSettings file MIA: @Driftwood Did you read https://doc.qt.io/qt-5/qsettings.html ? On Windows default location for settings is Windows Registry. Just read the doc and see that QSettings defaults to QSettings::NativeFormat, which uses the Windows registry, demonstrated in my first code block. And then settings->sync() "imports changes made by other processes (in addition to writing the changes from this QSettings)." Note to self: Read first :D @jsulm - Thank you.

@JonB I would like to do that with delegate. I also add EDIT in my last post for you. Now I think you understand my last problem :)

@kshegunov @Christian-Ehrlicher Thank you both for all the information. I guess I will just do something like: v.setValue( QByteArray(new_data, 1000) ); and not worry too much about avoiding memory allocations.
