Christian Ehrlicher 8de62d3432 QAbstractItemView::dataChanged(): optimize call to QWidget::update() ... When topLeft and bottomRight are different in QAIV::dataChanged(), the current implementation simply calls QWidget::update() without checking if the affected cells are visible. This results in a big performance hit when cells are updated frequently. Now try to compute the exact update rect by iterating through the modified indexes.
