[SOLVED]How Can I Convert QPainter System to OpenGL Painting System?

[Yanguam Siliagim]

Hi all! I used to create lots of graphics items inheriting QGraphicsObject for its paint() method in Qt4.8. Now, I find that the quality of QPainter could no longer meet my need and I want to use OpenGL system instead.
Are there any easy ways to update to OpenGL? I would also thank you very much if you can introduce some relating articles for me.
Footnote:I'm building my program with Qt5.3.
