Is QPainter enough in Qt or OpenGL?

Question

C++ / C#

I plan to write an application that will draw a graph, and in the future it will be possible to change their position by clicking on edges or vertices, etc. (after 2d, you may have to draw in 3D and rotate the already 3D image).
Actually, will QPainter be enough for me, or will I have to use OpenGL in Qt (I don’t know the first one, I had to work with the second one)?

Answer 1

QGraphicsView / scene - the most powerful yramwork that can do almost everything, even 3D, and it's a pleasure to draw and move objects in it

Answer 2

If there are no other reasons to use one technology or another, use the one you are familiar with.
