You are not really supposed to usesetCellWidget()for all these buttons, you're supposed to useQStyledItemDelegates. But @VRonin no longer seems to frequent this forum :(You need somehow to identify which row each button is associated with when you get the
clicked()signal. 3 ways:-
You will have to get the
QPushButtonsignaller and find which row it is on in the table widget. -
When you
connect()each button you are creating use a lambda for the slot, to which you pass an extra parameter of the row number. -
An alternative to #2 is to use QButtonGroup Class for each column of buttons. Use its
setId()to associate the row number, which will be passed by theidClicked()signal. This is the one I would do, for neatness.

how about hide, instead of delete?
@micha_eleric
Hide what, instead of delete? The OP is asking a common question about how to have a button against each row, to delete that row from the database, or similar functionality.
