如何在PyQt TableWidget中刷新数据？

Question

For example, I have a SQLite database and I grab data from this database and put it into QTableWidget . But then, I make some stuff with this data.

So, how can I update data in this table without setItem method?

Answer 1

Use a QTableView instead, where you can dynamically change the data in the underlying model (eg a QStandardItemModel ). In your case, you might even be able to simply use a QSqlQueryModel or QSqlTableModel with your database.
