iterate over the QList with the items and set the item hidden each time.

@QList<QGraphicsItem *> items = scene->selectedItems();
foreach( QGraphicsItem *item, items ) {
item->hide();
}

So don't use selectedItems() but items().

@Eddy: integrating the two ideas maybe faster. Before all items can be selected in a way that exclude a loop? I think it is difficult, because this is the usual way also adopted by graphic programs like Inkscape. BTW if it is possible only one shot to hide the selected items at all.
