Question

I want a signal to be emitted when I either click on a cell or use the arrow keys to navigate to a new cell of a QTableView. When I was using a QTableWidget, I used the currentCellChanged signals. However, I don’t see a similar signal in QTableView – is there nothing similar?

Thanks,

David

You can either use:

• the signal currentChanged(QModelIndex, QModelIndex) of the QItemSelectionModel instance returned by QAbstractItemView::selectionModel(), or
• derive the view and redefine the function QAbstractItemView::currentChanged(QModelIndex, QModelIndex).

PS: When the parameter is a const reference (so not const alone, or not & alone), you can omit both const and & in the SIGNAL and SLOT macros:

connect(tableView->selectionModel(), 
        SIGNAL(currentChanged(QModelIndex, QModelIndex)), 
        ...
