c++ - QGraphicsView with ~500 items causing rest of UI to lag -


as title says, in program i'm making have qgraphicsview contains lot of items, half of pixmaps. resource intensive, , can't expect display update @ 60 fps prefer. that's fine, it's important rest of widgets perform crisply. there way render qgraphicsview in separate thread, or otherwise update synchronously doesn't block other widgets?
