Alright, yep, that did it. In summary to use this you will need to have the following lib's installed: libqt5multimedia5-plugins libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev and you will have to have -gstreamer configured on your platform.

Sorting the base model is normally much more expansive than using a QSortFilterProxyModel so it should be avoided.

@artwaw said in QtSql Postgress MinGW8 compilation error.: I always use QtCore to avoid the plethora of single class includes. Looks like you have enough time...

@JonB Thanks i can handle every event in the bool QStyledItemDelegate::eventFilter(QObject *editor, QEvent *event) . Works enter key press ... calendar close and the valu set into the cells! Thanks again it works perfectly! :D

I will change the data in column 2 in the function setData() of the model class. After change data, I emit a dataChanged(index, index, {role}); Could you show this part of the code?

The solution turned out to be simple to the point of outrage: app.setStyle(QStyleFactory::create("Fusion"));

@SGaist, that has solved my problem. Thank you!

I fixed this buy changing C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat with C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsx86_arm64.bat., see https://developernote.com/2021/09/how-i-fixed-cmake-configuration-has-no-path-to-c-compiler-in-qt-creator/

@SGaist Great, thanks a lot for the information!

bump, bit of a necropost, but still an issue. @JonB said in OAuth2 QOAuthHttpServerReplyHandler HTTPS/SSL support?: @Alex94102 Here you go: https://bugreports.qt.io/browse/QTBUG-64615 any luck with getting QSslSocket bits into qoauthhttpserverreplyhandler ?? I am trying to interact with a service that has just started enforcing https for callbacks.

@Sai-Raul Start here: https://doc.qt.io/qt-5/videooverview.html

Yep I get that, and the source does reflect that as looking deeper in the source does show that the QStyleSheetStyle is run after my own QStyle. In that case, What is the standard process for painting widgets in a style-aware fashion? Do I need to forgo the palette and take colors from custom properties instead? Are there any examples of more complex paintEvents relying solely on QStylePainter (Drawing primitive, complex and control instead of rect, line, etc)

@huppeldepup said in QStandardItemModel: add columns to row before adding the row to the model?: How do it create my row outside of the model, add my columns and only when my row is complete... add it to my model? Create a QList of QStandardItems, one per column, and then call QStandardItemModel::insertRow() with the list. I am not sure how this interacts with the protected filter functions.

@LudoFR said in Is Qt the good tool for me.?: if I paid almost 4000$/year for V5.15 Not sure whether you mean you have already paid that or are still thinking about it. You can always look at the free/open source version of Qt first to see if it suits your requirements, before you determine whether you need a commercial subscription if you decide to proceed.

@Mr-MinimalEffort Unless you get a more knowledgeable answer: as far as I know stylesheet rules, and implementation, are a "black box" --- internal code which you cannot access.

Thanks for your advice. I found that I can prevent this error by directly converting it to QString in Q_ARG. The demo is like below QMetaObject::invokeMethod( /param/, /param/, Qt::QueuedConnection, Q_ARG(QString, QString::fromStdString("test")));

Hi, From the documentation, you are missing the valueName parameter.
