Hello all,

I am using QGraphicsView and QGraphicsScene to display thousands of points from a database.

Collecting the points from the database takes about 2 seconds but when i try to display them on a scene by using:

QGraphicsItem *item = new QGraphicsRectItem (x,y,1,1);
SampleScene->addItem(item);

it takes about 10 seconds to load the rectangles and then when i move the scene in the view it is very sluggish and takes a while to refresh.

Any ideas on making this faster to display?
Any hints or tips on using QGraphicsView to it's maximum potential?

John
