General and Desktop

@kehr_I You have my sympathies. QtCharts was a bit "dodgy" at times. Whether we like it or not it is going away, to be replaced by QtGraphs. I too have zero desire to use anything QML in my code (widgets). I believe it is "supposed" to be callable from widgets app --- presumably all QML/QtQuick stuff to support it will now have to be bundled with widgets app for deployment --- but I have a feeling there was a recent post saying the API "is not available"(?) from widgets, as of the present time at least. It might have said it works for 3D but not 2D. Ah, have a read of https://forum.qt.io/topic/159224/qt-graphs-building-2d-plot-using-c-only

@shreya_agrawal Found a hack for this. Morph the QToolButton to a QPushButton.

@Kent-Dorfman the error gives the SAME file - the moc file. What is strange is clean builds on Windows works (my copy using Beyond Compare leaves out the .user and build files) but not clean builds on Fedora. The CMake environment was done using QtCreator. And as I said, I deleted the build directory on Fedora and the problem still occurs. Still trying to get my Ubuntu environment to work (CMake can't fine Qt; I've fixed that before on older systems, but did not have time tonight) So far, it seems to be something due to Fedora or Linux. I did reinstall Qt from qt.io instead of using what fedora wanted to install. Same problem. This makes me wonder if it is due to differences between MingW (on Windows) and g++ on Fedora. If I try CMake directly on Fedora, it can't find Qt. Once I fix that on Ubuntu, I will see if I can fix it on Fedora. Thank you for your answer, and I will get more information

@GrecKo Yes, but I'd like it to be somewhat readable and manually editable. But I suppose I could save the type name instead of the id. Thanks.

@svadym said in QTableView performance: slow repaint of scroll area viewport: I can try to submit a bug report if you say that it's not normal. This would be nice. With a small reproducer (main.cpp only), a recent Qt version (6.9 and up) and some benchmark results from you. Also reduce the update rate to e.g. 10hz. It's fast enough - Noone can read that fast.

@Christian-Ehrlicher said in how to override qtcharts QBarSeries？: the export macros are wrong. Which is exactly what I wrote above in https://forum.qt.io/post/829183. I don't know about "name clash". Anyway if you are sure this cannot be done by adding a new subclass in own code then I am sure you will be right and the OP would be best just changing the existing Qt source.

@PuskasAlex said in QDesktopServices::openUrl() fails in Qt 6.8 on macOS for file paths with special characters ([, ]): There is any workaround? Except creating a bug report (search before if there is already one) - compare the code between Qt5 and Qt6 - maybe you can spot the problem.

@nicker-player I see that now, I did not notice it (if it was there) when I posted originally. I know nothing about QML, but file:///D:/program/qt/5.14.1/msvc2017/qml/QtQuick/Controls/Styles/Desktop/TableViewStyle.qml:109:13: Unable to assign QQmlListModel to QString looks to me like styleData.value is an actual QQmlListModel? Which obviously cannot be converted to a string. So, however you do it in QML, what it is the bound value (or its type) in whatever cell in your table?

Ah! It's PipeWire. pw-cat --record --target alsa_input.usb-Hanlincrest_Ltd._FUNcube_Dongle_V2.0-00.pro-input-0 --rate 192000 --format s16 sdr.raw sox -t raw -r 192000 -e signed -b 16 -c 2 sdr.raw sdr.wav ...results in a wav file with the same 20kHz filtering. Now I need to find out how to fix that. "Pro Audio" setting isn't working. I guess this is solved from a Qt point of view.

@Pedro-Vicente Check the config.log file or use -v parameter when calling configure to get more information.

@Khadeer Why do you need the Gnu compiler? Just recompile using clang from Android NDK.

@Zbigniew-Sch Thank you for your answer, I have solved my problem. I created custom MyWidget derived from QWidget and overwrited paintEvent method. Then called setGeometry in constructor method and called resize() when scaled. It works as I want.

@Christian-Ehrlicher Thank you very much !

Hi, Can you provide a minimal project that shows this issue ?

@Pl45m4 It was not intended ironically. It was like that when I last investigated, maybe copy/paste etc. is available now. I will check next time I am in Designer.

Jira ticket has been raised for Issue 1: QTBUG-138495
