General and Desktop

@Christian-Ehrlicher Done, Sir :-) I was just not sure, whether the fix happened in 5.15 or 6.2. The latter it is.

@kkoehne said in CMake +Qt6 +lupdate: cool - sounds to become easier and more flexible in 6.7. will test with beta2 And the NATIVE_TS_FILE option only will actually appear in Qt 6.7: https://doc-snapshots.qt.io/qt6-dev/qtlinguist-cmake-qt-add-translations.html I'm developing always in english, where in most cases german is used by customers. Because I'm writing code in 'developer-english' it may happen, that customer requests to change a translation. for these cases and to handle plural forms I always also add an en ts file, so I'm using .ts / _de.ts / _en.ts / _fr.ts ... this is working well because translations not found in _en.ts will come from .ts seems that in this case I don't have to set the NATIVE_TS_FILE, because _en.ts not only contains plural forms ? if setting QT_I18N_LANGUAGES will this work if my (from Qt 5.15 ported) .ts files are in project_dir/translations ? BTW: the lrelease command is executed automatically if building in QtCreator ? In 5.15 my workflow was: lupdate, Linguist, lrelease Now in 6.7 I can do lupdate automatically with add_dependencies(...lupdate) or execute manually with CMD-K cm ...lupdate and lrelease is always done automagically ?

@TomNow99 Not sure about Windows, but on Linux it's just: nm myApp | grep Qt_6 > /dev/null echo $? If it prints 0, it's a Qt 6 program, 1 otherwise.

@MartinD Did you solve it? I've got the same problem on Rpi CM4...

@Long-Vu-Ngoc I know, I saw it. Stick to that, you won't get any more help from here.

@Rozerchik Start by Googling for: qt.network.ssl: No functional TLS backend was found. There are quite a few topics. Have a read, see if any of them apply to your situation?

@whatabout said in Qt6 QImage never loads image but Qt5 worked: Was this the case with qt5? Maybe, maybe not - it depends on how you installed your Qt. Qt5 was modularized already in the Qt installer but Qt6 gets even more splitted to reduce the installation footprint so yes it might be the case.

@whatabout "because what you say is illogical." Well, then don't read the source if you don't believe me. I can just tell you that Liviu do it exactly like I wrote (and like it is also written in the Qt documentaion). When you think it is illogical, then don't do it and code only for Qt5 (or Qt6) - like you want. We code Qt 5 and Qt6 at the same time. It is easy.

@SiGa you can just use the topic tools and set the whole topic to solved

@jsulm Oh, this is stupid mistake. I'm tired and I can't see anything in front of me. Very grateful to you!

@tilz0R Yeah, tableView/treeView are notoriously slow in this area. In a case similar to yours, https://forum.qt.io/post/551198 I used a timer to update the view only a few times per second, not each time some data arrived: // constructeur DumpTreeModel(QTreeView* tree) : TreeItemModel(), _treeView(tree) { connect(this, &QAbstractItemModel::rowsInserted,this, &DumpTreeModel::rowsInserted); /** https://bugreports.qt.io/browse/QTBUG-61763 * QTreeView updates slow down with increasing delay if scrollToBottom is used */ _timer.setInterval(200); _timer.start(); connect(&_timer, &QTimer::timeout, [this] () { static int count=0; int rows=rowCount(QModelIndex()); if(count<rows AND _scrollToBottom) _treeView->scrollToBottom(); count=rows; }); } Don't get me wrong, it doesn't solve the problem, it only postpone it.

@jeremy_k Hi again Thanks everyone for helping me. I did manage to make it work by installing pip and setting the correct python executable as a parameter to the QProcess::start() function. My mistake was linking the wrong python (specifically, Microsoft's Python) For anyone wondering here is my working code QProcess process; process.start("C:/Users/boyan/AppData/Local/Programs/Python/Python312/python.exe", QStringList() << "C:/Users/boyan/Desktop/sd.py"); if (!process.waitForFinished()) { qDebug() << "Error: " << process.errorString(); } else { qDebug() << "Process finished successfully."; // Read standard output of the process QByteArray outputData = process.readAllStandardError(); QString outputString = QString::fromUtf8(outputData); qDebug() << "Output:" << outputString; }

@JacobNovitsky But how to adjust it using Qt Libs? Either version of QWidget::setTabOrder()

@AnneRanch said in Qt Creator rebuilds all headers and cpp files to new objects: this does not help you You asked the very same question in this post. As usual, you got a polite answer. As usual, you did not reply. So we don't know if it was helpful or not. Thanks for calling my answer stupid and not helpful. Made my evening.

@tedburns hi and welcome to devnet, The example in the blog wrote that the Python file should have the same name as the class. This implies that the file shall have a .py extension as rightfully noted by @JonB. In C++, uic will generate the required code if you want to have a full class (you usually want that) and build it. In Python, you have to follow the same logique and generate Python code out of the .ui file if you want to extend the widget with code.

@Akshaya-Shanker Since this says qrc:... it means the file is embedded into your application executable, so you can't see an external file. I haven't used it, but presumably either you added this file into your project in Creator as a resource, in which case you can see it there, or else why not search the whole of the Qt installation area for a file named qwebchannel.js?

@grafenocarbono said in How can I see the microprocessor register values using Qt?: Can I introduce assembler functions into the code in Qt Qt has nothing to with this, it's just a C++ framework. You can use inline assembler code in C++ or a stand alone assembler with assembler code files.

@hunter-Li QAxBase::setControl: requested control Word.Application could not be instantiated QAxBase::dynamicCallHelper: Object is not initialized, or initialization failed QAxBase::dynamicCallHelper: Object is not initialized, or initialization failed Although I know it's a permission issue, is there a better solution?

These are exceptions so you can catch them. Start your app in a debugger and see where exactly they occur.
