    Hi and welcome to devnet, Looks like you got the sources of that library. Build it, install it and then you can use it.

    @itanitarek10 said in workerThread.wait() gives heap corruption errors: connect(&workerThread, &QThread::finished, &workerThread, &QObject::deleteLater); What do you expect from this connect at all? And no I did not tell you to change it this way...

    There is no need to reset the series afaics. QChart::update() should suffice. If not please provide a testcase.

    Hi, You might be requesting a format that is not supported by the default output of your system. Check your device and what they currently supported.

    As already written: Use GStreamer. It provides all the tools for both generating the stream in an adequate format, so server side, as well as read said stream, so client side. And, again, as already written: use QMediaPlayer::setMedia with a custom pipeline if needed to show the video on your application.

    Hi You can look how QFrame does. void QFrame::drawFrame(QPainter *p) { QStyleOptionFrame opt; initStyleOption(&opt); style()->drawControl(QStyle::CE_ShapedFrame, &opt, p, this); } However, it would be easier to just inherit from QFrame instead so you can just set properties and not values in QStyleOptionFrame.

    Well, that one should be updated by "Update components". I'm not sure why you got no updates available. Maybe it is the network thing? Or maybe your maintenance tool is too old to be updated, in that case you can only remove all components and download the latest online installer.

    @mrjj Thank you for replying . I may misunderstand virtualGeometry(). I guess a same way to get x or y coordinate using screen and screen.virtualX from screen in QML , is the way to use screen->geometry().x() in Widget. Is it correct ?? Because I thought the virtualGeometry() in Widget is same as the screen,virtualX in QML...

    Beautiful...thanks, Bonnie. (The worker doesn't block; it's really just a bunch of signals and slots connected to the widget.)
