Is there a signal in QTableWidget that “fires” when a cell has lost focus?

[jacek]

Maybe this will help?

void QTableWidget::cellChanged ( int row, int column ) [signal]
This signal is emitted whenever the data of the item in the cell specidied by row and column has changed.

or this:

void QTableWidget::currentCellChanged ( int currentRow, int currentColumn, int previousRow, int previousColumn ) [signal]
This signal is emitted whenever the current cell changes. The cell specified by previousRow and previousColumn is the cell that previously had the focus, the cell specified by currentRow and currentColumn is the new current cell.
