Qt objects which requires X11 server

[CloudCompany]

Hello everyone!

I'm currently building an API for a software which can be launched on a Console.
This API use some part of code which is used in the GUI version, and the API fails sometimes because it needs an X11 server.
My question is: Which Qt libraries/objects needs an X11 server ?

For example, I changed all QPixmap objects into QImage because QImage does not need an X11 server.
Do you know if a list of these objects exists ?

The documentation of each class specifies to which module the class belongs. Alternatively, you can get a list of all Qt classes by module (http://doc.qt.io/qt-5/modules-cpp.html). For a console application, stay clear of every GUI-related module, such as GUI, Widgets, QtQuick, etc. As long as you RTFM of each class you use, it will be easy to sort them out.

Thanks for your reply.

I was searching in the documentation before create this topic.
I thought that there was a cheat sheet on this subject, but I am wrong.

Classes from QtCore never need any graphics system resources.
Classes from QtGui might.
With Qt5 one can also use a platform plugin that does not use X11 and then use almost all of QtGui

If all else fails you can fake an X server with Xvfb, but that requires some external fooling about.

Thanks for your replies, I will continue check documentation and test Xvfb.
