How to disable gui while creating QApplication object in QT 5.6
-
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.

I have not used Qt 4.But at Qt 5 you will need to use http://doc.qt.io/qt-5/qcoreapplication.html (
QCoreApplication) for non-GUI app.QApplication&QGuiApplicationderive from that, but specialize to require a GUI.
