@artwaw thank u so much for trying to help me out, but now after i reopened the app to see the compile output and send it here, i decided to try running it for the last time and see if it works, and it actually worked!
thank you so much for you attempt 🙏

@Futuray-Programming That's what WebEngine is made for.

@jsulm I used to believe that the only way to create a C++ GUI was through Qt Design Studio, as I had never created anything in C++ other than console programs. I've created a GUI in Python in the past with it. However, I stumbled upon examples in Qt Creator that use .ui files. I'm familiar with this approach, having worked with UI and widgets before. I believe I'll continue using widgets since they don't show any errors when the program is executed.
I will close this conversation as I no longer require assistance with qml. If I encounter any further issues, I'll post on a forum if I'm unable to resolve them myself. Thank you to everyone who tried to help me.

When you want to use the operator !=() you have to provide it - a compiler can not simply create the operator!=() from the operator==().

It looks like it's statically building. When I go into the directory, inside the bin folder there is no dlls, when I do the lib /list some.lib, it shows how .obj files instead of .dll files. Weirdly enough, when I statically compile with the dynamic dll version of QT, it compiles fine, although it still requires the dlls.

@rogerccs said in [Issue] Qt Creator doesn't allow me to add files to projects, only the .pro file:

And after loading the example, the .pro.file is remade.

Yes, that's correct.

Deleting the .pro.user file does not solve the issue. I get the same message.

I don't know then, sorry. Your setup looks good. I'm not using Windows 7 since many years, maybe it's something specific to that version.

@Kevin470 Hi, I have exactly the same problem with you and i also have Trend Micro Security on my laptop. I have been searching this issue for a few days. Have you tried to close the antivirus software? Could this solve the issue?

I managed to solve it by moving an #include (of the class that has the #include "ExpressionEvaluator/exprtk.hpp" in it) that was in a .cpp file to the .h file and putting it before the #include of the class that has the #include <windows.h> in it.
Thanks everyone for the help.

@artem1997262 said in QMYSQL driver not loaded on Ubuntu:

Although below shows found that file

Where is it located?
And did you check whether it is 64bit this time?

i resolved this. Perhaps someone will be useful. I had cmake 3.24-rc4 and they broke something with it. Here is the link: https://gitlab.kitware.com/cmake/cmake/-/issues/23759

Rolled back cmake to 3.23.3, everything works fine

@SGaist thk for trying to help

@JonB Shifting it to before any other includes got rid of the error.

There were no other details in the error messsage.

@JKSH Yes now It's working Thank you so much!

You have to register the expected Response first!

In my case it was like

#include <QtDBus/QDBusMetaType> // ... typedef QMap<QString, QMap<QString, QVariant> > ConnectionDetails; Q_DECLARE_METATYPE(ConnectionDetails)

and

int main() { qDBusRegisterMetaType<ConnectionDetails>(); // ... }

@TrahdBoy hi,

It's all explained here.

Hi Siddhartha,
I am facing a similar issue, have you figured this out? If yes, then could you please help, thanks in advance.

@RekTekk249 said in Tons of error for no obvious reason:

Two hours ago, everything was going well, until I realised I needed the same instance of my helper class in my MainWindow than in my LoginWindow.

If you would have posted the whole file, esp. showing the parts you've changed, it would have saved a lot of troubleshooting ;-)

It's also a debugging thing... If you made changes and suddenly nothing works anymore, revert the changes and try to figure out why it happened.

Thank you to all the panellists, I’ll take care of it.
Can we leave it open in case there are any mistakes or questions?
