OpenGL with Graphics View?

[Dutch112]

I am making an application that has a lot of animations going on and would like to make "pure" opengl calls to do this.

Right now I am using the GraphicsView framework and add a bunch of items to the scene. Some items are simple, like buttons. Others are rotating images, for example I have 25 fans rotating on the screen. For this I am using the time line stuff.

I already set the viewport to qglwidget but the hardware I run this on still gets bogged down a bit.

Could I do something like this:

MyQGraphicsItem::paint()
{
    quad(x1,y1,...)
    glRotatef(...)
}

MyQGraphicsItem::paint()
{
    quad(x1,y1,...)
    glRotatef(...)
}

To copy to clipboard, switch view to plain text mode 

Or would I have to overpaint in a QGLWidget to do this and not use the graphics view framework?
