Warnings.

Hi All, when I try to compile and run the program, it gives me the following warning. Heres the screenshot.

I understand that warnings can be ignored but should I be concerned about the above warnings?

Its alright. Hi All @J-Hilk @JonB and @Pl45m4 I have solved the situations.

I have to put 3 lines

    qputenv("QT_AUTO_SCREEN_SCALE_FACTOR", "1");
    qputenv("QT_SCREEN_SCALE_FACTORS", "1");
    qputenv("QT_SCALE_FACTOR", "1");

in the main.cpp file and in whereever I want to create a new window from my application.

As you say it's only a warning, but, yes, anything "deprecated" is worthy of being changed over. A future release of Qt may remove support for something "deprecated", and then you would have to act on it, so why not get it done now?

Yes, same way as you can go on without food. You'll be fine for a while but eventually everything collapses!

therefore

DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000

is your friend ;)

In all honesty, you can go with ignoring it, or if you like a clean console output, deactivate that particular warning via removing DEFINES += QT_DEPRECATED_WARNINGS from your project file.

But IMHO always handle warnings as errors. Your future self will thank you for it!

This warning contains also the solution. Replace QT_DEVICE_PIXEL_RATIO with one of the suggested modes or vars. Then the warning should be gone.

@JonB Hello I am using QT 5.12.6 the Latest LTS for Open Source Version for my own Project. So, I am not sure why it is giving me this error

@J-Hilk I have put the

DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000

into the .pro file and it still gives me the error. I have also removed the DEFINES+= QT_DEPRECATED WARNINGS
from my .pro file.

However, it is still giving me the warnings. Any idea why? I have also restarted the QT Community after I made the changes

@Pl45m4 How can I do so?
