Qt declaring member names using a loop

I need to work with 512 individual rectangle items in Qt which I am implementing in a QGraphicsScene. I don't really want to declare all 512 elements manually unless I really have to. At the moment I have something like:

QGraphicsRectItem *rec1;
QGraphicsRectItem *rec2;
QGraphicsRectItem *rec3;
QGraphicsRectItem *rec4;
QGraphicsRectItem *rec5;
QGraphicsRectItem *rec6;
QGraphicsRectItem *rec7;
QGraphicsRectItem *rec8;
QGraphicsRectItem *rec9;
QGraphicsRectItem *rec10;
QGraphicsRectItem *rec11;
QGraphicsRectItem *rec12;

etc etc. This will have to go up to rec512.

I have tried to implement a for loop to do this for me:

   for(int i = 1;i=512;i++){
        QGraphicsRectItem *rec[i];
    }

However I get an error saying 'expected member name or ; after declaration specifiers'

I'm thinking its not possible to implement a loop here, is there any other way to easily declare all 512 items?

Thanks :)
