General and Desktop

@JoeCFD Thank you so much! The InCirc/OutCirc curves worked!

I, too, have reinvented this wheel. I was "spoiled rotten" (on this axis, anyway) by using wxWidgets, which does imbue its assert macro with an optional "assert-then-continue" feature. Here you can find my cobbled-together variation on this theme, which works on Linux and Windows. (it also worked on Mac a while back, but I haven't tested recently, and MacOSX has been changing at a fast pace.)

The problem should be in QModelIndex DemoModel::parent(const QModelIndex &index) const row in returned QModelIndex should be relative to grand parent. Thanks

@JonB I have Qt-Version 5.15.3.

My problem was solved in this Thread: https://forum.qt.io/topic/131616/does-qsqltablemodel-have-a-limit-of-records

Hi, Which version of Qt ? On which OS ? Can you provide a minimal compilable example that reproduces that behaviour ? Did you check the old and current values ? How do you implement your widget hiding ?

@SPlatten , solved, the layout was contained in a widget: mpobjErrors->setStyleSheet("background-colour:#ff0000;");

since 29 March 2021 until today (already 7 months), the application not crashing anymore due to every midnight i did restart the operating system Windows Server 2016. Today i just had meeting with our vendor, the vendor still saying nothing wrong with the application , not admitting their application that caused the crash problem, and blame our server's operating system that having problem. I am not programmer/developer so i have nothing to say. At the end of the discussion, our vendor informing us to use Linux Red Hat operating system which they claimed no issue. I will discuss internally about this.

@Paul-Colby thank you

@SGaist said in Replace (MIME)=(*): Hi, Since there's no question, are you asking why the regular expression you are using to replace =* does not work ? That's because * has a specific meaning in regular expressions. It means 0 or more times the preceding expression. So if you want to detect in a string you need to escape it. On a side note, you should move to QRegularExpression as QRegExp has been deprecated in Qt 5 and removed in Qt 6. Done ! //s.replace(QRegularExpression(MIME + "=*\n"), MIME + "=" + FI.fileName()); s.replace(QRegularExpression(MIME + "=.*\n"), MIME + "=" + FI.fileName() + "\n");

UPDATE Fixed by swithing to fcitx5. BTW, it crashes by accident and be solved by deleting ~/.config/fcitx5 and reconfiguring. @SGaist said in QLineEdit in Qt6 not work with fcitx: did you try a more recent version of fcitx ? Not yet, it's said fcitx 4 is under maintance only now, I'll try fcitx 5 Thanks

@SGaist, that was the issue. Now, with these in else block: else{ diff = abs(diff); for (int i = 0; i < diff; i++) { auto line = lineEdits.takeLast(); delete line; } } it shows the right number of line edits in header and the qDebug output is also correct. I haven't measured the time BUT feels like this approach is little bit slower than the previous approach (removing all old and adding new). I also have removed this connect(this, &TableHeader::sectionCountChanged, this, &TableHeader::onSectionCountChanged); and call reset directly in the TableWidget: void TableWidget::queryDatabase(){ db.open(); tableModel->setTable(tableName); tableHeader->resetBoxes(tableModel->columnCount()); tableProxy->setQueries(tableHeader->getQueries()); tableModel->select(); while (tableModel->canFetchMore()) tableModel->fetchMore(); db.close(); }

It does what the documentation describes. There is also a note: "Note: This function does not change the structure of the model or modify the data available to views. In other words, the "root" of the model is not changed to include only files and directories within the directory specified by newPath in the file system." Pass the returned model index to https://doc.qt.io/qt-5/qabstractitemview.html#setRootIndex

@Dy3zz said in Cannot create QJsonDocument from a QJsonObject: I got the next error: variable has incomplete type "QJsonDocument". Any ideas what i am missing? Thank you #include <QJsonDocument> ?

This issue has been solved at c++ - QAudioInput: failed to open audio device. Solution: 16bit audio must be signed integer. DataFormat.setSampleType(QAudioFormat::SignedInt);

Just to close this: I rearranged my code so that I don't need to cast interface pointer and removed Qt-signal connections. Works perfect with own written Interface-callbacks.

Just to close this: I added a timecode check and this way I could sort out the unwanted/wrong keyevent.
