Use an opengl context from a library inside a QTwidget/window

[RoiG]

Hello!

I have a dll library that is using SDL2 to make a window and a opengl context (and drawing something). What I want to achieve is to use QT to initialize that dll and use the opengl context from the library inside a QT window or widget dont know yet the difference. I know that it should be possible, but I'm new to QT world, could someone give me some directions just to start digging into it?

Thank you.
