@adhn QMqtt is not free for commercial use. if you sell your product, you may want to check the source code of this module or find other example code to learn how to hook mqtt up with qt object. Update of data every 2s seems ok.

Hi, In addition to @Pl45m4, offline installers have been a thing of the past for quite some times now of the OpenSource version of Qt including the one you're after.

I don't see a problem here - even the windows explorer allows resizing a section behind the view.

@cuijg said in layout stretch error?: if stretch setting 1,0,0, it's right；but if setting 0,0,1 it‘s error； What error?

@aha_1980 thank you. Actually this is the first attempt I tried: perhaps I did something wrong, however if I override mousePressEvent with one containing QComboBox::showPopup() nothing happens, also because showPopup should be reimplemented. I fear that for obtaining the behavior I described something more involved should be done, unfortunately. Grazie mille Buona giornata

See also QProcess::startCommand(), which seems to be equivalent to passing the results from splitCommand() into start(). This was introduced in Qt 6.0.

Like previously stated, the only real option you have is to start a separate process from your Qt application. This process loads the DLL and performs the calculations. You can then terminate that process at any time, and the operating system will take care of cleaning up memory, handles, and other resources. The only potential downside is the risk of corrupted files, if the DLL performs file operations. Communication between your main application and the second process can be handled via QSharedMemory, QLocalSocket, or standard input/output piping.

@CJF-the-Elder that's exactly what's written in the docs I linked...

Ah, found this issue right after posting while doing some more thorough review of my overridden methods. Hopefully it helps someone else. For those converting QSqlTableModels to QSqlRelationalTableModels be careful what methods you're calling! In the below code I forgot to update the base function call to QSqlRelationalTableModel so it was still calling QSqlTableModel::insertRowIntoTable(const QSqlRecord &values) which led to these issues. bool PolicyModel::insertRowIntoTable(const QSqlRecord &values) { QSqlRecord rec = values; rec.setGenerated(Policy::DataRole::Id, false); return QSqlRelationalTableModel::insertRowIntoTable(rec); } I had overridden this method because the primary key is an AUTO_INCREMENT field.

Hi - did you manage solve your issue? I'm working on some sort of 3d level editor and will be implementing undo/redo soon, so I may come across the exact same problem...

Your path is to long. Move to a shorter path.

@Christian-Ehrlicher said in QLabel with custom word wrap mode: I would not override the paint event. Don't see why it would be needed. Maybe I miss something, but how then I can make QLabel support wordwrap not only on word-breaks or add elided text support?

A much easier solution is to use a GridLayout instead, with each column having a HBoxLayout of the left, middle and right button groups.

Same situation , any update ?

After I have added to the path the xml.exe that supports the 'sel' argument the Qt 5.15.16 was built correctly

See https://doc.qt.io/qt-6/qcalendar.html#monthName

Not sure if this is the issue, but worth trying... I see you're using the non-Locale overload of QTranslator::load(), which specifically says: Usually, it is better to use the QTranslator::load(const QLocale &, const QString &, const QString &, const QString &, const QString &) function instead, because it uses QLocale::uiLanguages() and not simply the locale name, which refers to the formatting of dates and numbers and not necessarily the UI language. So try using the locale-overload: https://doc.qt.io/qt-6/qtranslator.html#load-1 For example, here's how I do it in one of my projects: const QLocale locale; QTranslator appTranslator; if (appTranslator.load(locale, u"cli"_s, u"/"_s, u":/i18n"_s)) { QCoreApplication::installTranslator(&appTranslator); } ... qCDebug(lc).noquote() << "Locale:" << locale << locale.uiLanguages(); #if (QT_VERSION >= QT_VERSION_CHECK(5, 15, 0)) // QTranslator::filePath() added in Qt 5.15. qCDebug(lc).noquote() << "App translations:" << (appTranslator.filePath().isEmpty() ? u"<none>"_s : appTranslator.filePath()); #else qCDebug(lc).noquote() << "App translations:" << (!appTranslator.isEmpty()); #endif So try something like: const QLocale locale; qDebug().noquote() << "Locale:" << locale << locale.uiLanguages(); QTranslator translator; if (translator.load(locale, ":/qt/....")) { .... } You might also try to calling QmlEngine::retranslate() after the QmlEngine construction?
