When to use QTableWidgetItem?
-
Is it a case of use it when you need to, or should you always create an instance for every cell of a QTableWidget? A related question: is the QTableWidgetItem object purely a conduit to pass values to a cell of a QTableWidget object (so that the QTableWidgetItem object can be immediately deleted)?

Hi @Guerrian, welcome to the forums.

Yes, the typical usage is to create a new QTableWidgetItem if you change the cell, see the example at http://doc.qt.io/qt-5/qtablewidgetitem.html#details
A related question: is the QTableWidgetItem object purely a conduit to pass values to a cell
of a QTableWidget objectYes, that is correct.
(so that the QTableWidgetItem object can be immediately deleted)?
No, you don't delete it! The QTableWidget takes ownership of your QTableWidgetItem: http://doc.qt.io/qt-5/qtablewidget.html#setItem so you are no longer responsible for that.
