How to disable GUI while craeting QApplication object in QT 5.6

seetharam

Hi ,
One our Operating systems does not have X server.
To run our QT application in Console mode in non- Xserver machine , I have used below QApplication constructor.

QApplication::QApplication(int & argc, char ** argv, bool GUIenabled) -> supports in QT 4.8
Now we have upgraded our QT software from 4.8 to 5.6 .
In QT 5.6 , above QApplication construtor is not supporting. In our appliation we are inheriting a class from QApplication and initialising many other objects in that class and we are showing a splash screen before launching main application.
Now I am not able to run my application in console mode.
TO resolve this I think I need to duplicate my classes and inherite the duplicate class from QCore application .

Could you please let me know , if there is any way to resolve this issue in simpler way.

Regards,
Seetharam

It really is best not to post identical duplicate threads....

Hi
Yes you need to refactor your code and use
QCoreApplication and QApplication depending on console or GUI mode.
No way around it as its how it works now.

No point you spending your time here, because the post is also duplicated a 3rd time and answered, as per https://forum.qt.io/topic/89993/qapplication-not-working-as-expected-with-3rd-paramaeter-guimode/8 ... :(
