Qt 6

@jsulm
Hi,
Thanks for your reply and help.
I found a solution like this, https://copyprogramming.com/howto/detected-new-usb-device-connected-disconnected-on-qt
I made a class and when I plug/unplug my USB camera, there can receive WM_DEVICECHANGE in my class.
I will also try what I mentioned in my library.
Have a nice day.

@Nikita-Kobzev said in How to navigate in Qt documentation:

Hi, there is doc.qt.io. Is there a structure to it? As I read it and click on each link, I always end up on a page that I can never find again in the table of contents.

I have this problem occasionally. Most of the time, Creator/Assistant's index search avoids the issue.

Example 1: https://doc.qt.io/qt-6/qtqml-modules-cppplugins.html

I'm not sure about this one, without resorting to an index.

Example 2: https://doc.qt.io/qt-6/qtqml-cppintegration-overview.html

https://doc.qt.io/
-> "Qt 6" in the center iframe
-> "Qt QML" in the center frame
-> "Integrating QML with C++ Applications" in the right frame
-> "Overview - QML and C++ Integration" in the center frame

How do I navigate from the documentation root to get to those pages?

Hopefully in use, this is mostly an artificial problem. Starting from an example seems to generate better navigation from problem to solution for me, but I may be too far into the mindset to imagine a blank slate.

Thank you very much for clarifying my issue ! 👏️👏️

Hi and welcome to devnet,

Which version of Qt are you using ?

To the best of my knowledge, there's no option for reverse play.

As for the resource issue, the native backends cannot access the files within the resources. You have to copy the file in a temporary location and play it from there.

@elahav good point. We can even improve your suggestion: git submodule update --init qtcharts.

@StudentDev9923 I use TabBar of QtQuick.Controls to create tabs. No issues with Qt 6.6.1. Maybe you can show some code and your problems.

Also check out the nice example of Qt 6 under quickcontrols/filesystemexplorer/Sidebar.qml for horizontal or vertical layout.

@jiapei1000 please set -no-feature-native_grpc or -DFEATURE_native_grpc=OFF when configuring Qt/QtGRPC. This will unblock your build.

@eyllanesc so do I. add this code : QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);

@QMLEngine said in DDS image format plugin:

CMake.txt file in the folder of dds but still I couldn't see dds in QImageReader::supportedImageFormats() supported image format.

And did you acutally compile and install the dds plugin afterwards?

@david-azolai said in Undefined reference to staticMetaObject:

I have the same problem and use CMake , what can I do?

Show your CMakeLists.txt and describe exactly what you're doing / trying to do.

@Xinlong Yes, you can not mix different msvc runtimes in one executable.

@paulmasri
Hi, I'm encountering the exact same issue with Qt 6.5.1. Have you found a solution yet?

@Christian-Ehrlicher Okay, I understand. Thank you

Just this was asked the other day, there will be a recent thread for this maybe a week ago. the sad upshot was that it appears to be a PySide issue, with currently no known fix. I asked the other poster to try with PyQt instead of PySide and it worked fine....

EDIT
It's https://forum.qt.io/topic/152615/why-does-calling-dynamiccall-and-querysubobject-always-get-an-error-in-qaxwidget , and you were the poster, though you don't even reference that from here which would at least have been helpful. So you already know the answer, what's the point of this new thread? You know what the problem is, and you know there is apparently no solution with PySide6, so....

Have you reported this on the Qt bug tracker? You really need a Qt PySide developer to have a look at this issue.

@Axel-Spoerl
Thanks for your support Axel.

Finally, the issue was solved. I saw the path of main.qml and added the AudioInfoBox.qml file the same way, with the same path prefix. I added the AudioInfoBox.qml file like this.

Now it's working fine! 👏️

@Dmitriano
Sorry, have you the script to compile 5.15?

Thanks
