Handle KeyRelease or KeyPress on any row in QTableView

How Can I Handle KeyRelease or KeyPress on any row in QTableView ?

e.g. i want to handle when DELETE key released to delete the selected row in QTableView, How can i do that ?
Also, INSERT key to insert empty row so the user can edit it's data to be as a new row, How ?

Have you tried subclassing the control and overriding keyPressEvent? Or installing an event filter on the QTableView?

thanks but, ..
Can you give me an example ?
