Nevermind, I figured it out... So it seems that setSource reasonably expects you to actually have stopped the media beforehand. Doing so and adding a small wait works like a charm and indeed plays it asynchronously! Relevant example. m_player->stop(); QThread::msleep(100); m_player->setSource(url); m_player->play();

Sorry, I misunderstood the macro documentation. What about: qt_import_plugins(myapp INCLUDE_BY_TYPE tls Qt::QTlsBackendOpenSSLPlugin ) ?

@Pl45m4 Ohhhhhhhhhhh, I never noticed..........

@Rozerin-YILDIZ said in How to set color of QChart background to radial gradient?: I can change the color of background of qchart with this code: chart->setBackgroundBrush(QBrush(QColor("salmon"))); If you set a plain color, you can't expect to receive any gradient... Use QRadialGradient. https://doc.qt.io/qt-6/qradialgradient.html#details

@jsulm I already had mesa-libGL-devel and most of C dev libs as listed but installed it anyways, also today the installer was updated to 4.8.0 from 4.7.0 but it still doesn't work out of the box. Managed to run it by going to the ~Qt/Tools/QtCreator/bin and running it with QT_QPA_PLATFORM=wayland ./qtcreator and according to xlsclients it does indeed run in wayland mode.

@Psyger00 said in Program crashes (without error message) when attempting to read a second file into my program: Could you explain what debuger in this contect? Debugger to debug applications. Like GDB on Linux. If you're using QtCreator it already integrates the debugger, just build your app in debug mode and run with debugger.

@MasterQ Check your build directory! Perhaps "devel. db2" is right there! https://doc.qt.io/qt-6/qsqldatabase.html#setDatabaseName "For the QSQLITE driver, if the database name specified does not exist, then it will create the file for you unless the QSQLITE_OPEN_READONLY option is set." I ran your code,"devel. db2" was created。

Hi, When you say move, do you mean you kept it as is or did you refactor it ?

In the end, the mistake was very simple, in final image reconstruction Format_ARGB32 was used instead of Format_ARGB32_Premultiplied, causing these problems with drawing. Thanks everyone for help!

This issue is so common on this forum that it would deserve a pinned link somewhere IMO.

@MarisaG said in setting default file extension when creating a new file...: I do want it to look like a native app, so i like the way this is working other than the file list Yes, understood. But have you tried it? :) If you try Qt's FileDialog (QFileDialog::DontUseNativeDialog flag set) and there is only one "All Files" left, then you know for sure that it is Haiku's default file dialog that has its own "All Files" (which Qt has no control over).

I have already access to this statemachine and statemachine->configuration() gives me the state after i left the substate/historystate. I want to know if a historystate was entered or in which previous state it was. Lets say i have two different historystates in my statemachine and i have a stop/resume logic. "stop" jumps out of active substate/historystate and "resume" continues the last active historystate. The moment when i trigger "resume" i want to know which historystate was the last active one. I could save that information as member variable but i was hoping that QHistoryState delivers enough information.

The QTablewidget in a QWidget. So I tried to use style sheet in the QWidget. That solved my problem.

@Sajjad-Ali Quite apart from @JonB's observations: Your receiver is not listening. You need to look at QTcpServer You need to ensure that the receiving end does not have a system firewall blocking whatever port you are listening on.

@mpergand Hello, I have posted more stuff related to my task and it may look as negative toward you. I am posting this to make sure it is not interpreted that way and woudl like to let you know that I do appreciate all the help you have given me. The whole idea of automatic re-tillling of QMdiArea subwindows after one is deleted , was really just "bells and whistles ", nice to have and not essential for my project. This is / was an extremely (sic?) positive , hence beneficial experience for me, with an exception of uncalled for "contributions" AI / RTFM style. I realized that big part of the mess was my silly way to keep the Qt example and add QMdiArea to it. Then I ended up with two instances of same class and it was not easy to keep track of which is which. It really does not matter I did not end up with working code, but I sure can reuse it in my next "GUI class hierarchy " - another B&W project. Yours truly MFTR

@ian28 you can update or reset style sheet at running time.

@xylo212 why don‘t you google for it? you would have found this library. it also has an example to generate a png from the data in the examples folder.
