[Qt-interest] Which one is better? Graphics View or paintEvent()?

[程梁]

Hi, there! I want to develop a drawing and photo editing program.
It may be like Photoshop or Paint.NET with items drawing, photo loading,
processing, filters and layers.
But I've no idea which one to choose to implement this program. At first I
chose Graphics View it is simple
to add items but I don't know is it still simple to do some process on
photos such as some image filter algorithms?
Or should I use QWidget and override its paintEvent() in order to get this
feature? But if this is the better way, I'm
afraid I have to create classes as QGraphicsItems?

Now I don't know which one is better, could you give me some idea?

Thank you all and have a happy holiday!
