Qt 6

@sierdzio I replied to someone else by mistake. I noticed it late. It seems similar to what I found. Link: https://stackoverflow.com/questions/70373606/how-to-fix-qt-requires-a-c17-compiler. Thank you for the detailed explanation. In my case, although I don't encounter errors, it seems I need to reconfigure the C++ standard language setting. Thank you

@Ash-V
May I ask: I thought you were a "beginner" at Qt, maybe C++ too (but perhaps not). If you know what you are doing, and have a good usage case, using all the Q_D and d_ptr stuff may be fine. But I, and most people, have never used them, so I just wonder whether you might be over-complicating things.

@Teemo-of-LOL said in Question about Qtftp.:

Does the qtftp functionality also come included in Qt5compat?

No, QFtp is a separate library. As we already told you, you have to port them by yourself if you need it or use QNetworkAccessManager.

May be this is a window11 system problem. now this problem is disappear

@Christian-Ehrlicher Thank you very much!

Just open the 32 bit MSVC command prompt instead the 64bit one.

@JonB
Thank you Jon !

Thanks for giving this additional valuable reply....

@Axel-Spoerl
Thanks Axel !

Thank you very much for your valuable reply !

@JonB said in Issues with the new Qt version using the older compiler:

I don't know what "imported the old Q5.5.0 compiler into Qt6.6.2" means

I expect the latter to be QtCreator.

What I find more interesting is the mention of 5.5
That release was tagged June 2015

@SGaist thanks! It could be a good solution but for a while I don't know how to build external libraries for Android and WebAssembly. I want to be able to make build executables of my applications for Android, Desktop, and WebAssembly. It is why I like Qt very much because it has built-in libraries for parsing XML, JSON, drawing with build-in OpenGL ES, and WebSockets library to make multiplayer game clients for Android, Desktop, and Web. I want to host Node.js game servers with physics engine on free hosting render.com I don't have time to study how to build external libraries for Android and WebAssembly. I only know how to build OpenAL-Soft for Android to play 3D sounds and how to call Web Audio API from WebAssembly.

@tunga had you solved the problem? Just for an experiment try to use jdk-17 and try to make these steps:

set an another path for Android SDK location (create a new folder for Android SDK) try to press Set Up SDK and Open Android SDK download URL buttons:

@SGaist
I set QMAKE_RPATHDIR += /usr/local/lib in pro file.
Thanks for your reply and help.
Have a nice day.

@DesiVideoGamer don't know about "like qt5" but do look at the flickDeceleration property.

Edit; I personally prefer it at something like 3000

@devil_coder said in Different behavior in Qt5 and Qt6 with respect to QML files:

Specifically, behavioral difference when clicked was the main reason why I am suspecting z order can be causing the issue.

As you have the code, and we don't. Please confirm that by playing with the z index in that qml.

Please report back your findings.

@mercotui Thankyou! This worked for me aswell

@JoeCFD
Thanks for your reply and help.
I did what you mentioned, but it was failed.

Have a nice day.

@JonB

Last edit my code :

DataReceiver::DataReceiver(QObject *parent) : QObject{parent} { _manager.setAutoDeleteReplies(true); } void DataReceiver::start() { _connection++; if(_connection > 1) return; _takeData = true; run(); } void DataReceiver::stop() { _takeData = false; _connection = 0; _data.clear(); } void DataReceiver::getData() { _data.clear(); QString url = QString("http://localhost:%1/sample").arg(_port); QUrl _apiUrl(url); QNetworkRequest _request(_apiUrl); _reply = _manager.get(_request); connect(_reply, &QNetworkReply::readyRead, this, &DataReceiver::onReadReady); connect(_reply, &QNetworkReply::finished, this, &DataReceiver::onFinished); } void DataReceiver::run() { if(!_takeData) return; getData(); } void DataReceiver::onReadReady() { _data += _reply->readAll(); } void DataReceiver::onFinished() { emit sendData(_data); run(); }

its working. time slow down from 65ms to 165ms but its working.

@JonB
Thanks I'll read the link and ask if I don't understand!
