Displaying QSqlRecords on QTableWidget (double precision problems)...

[antoniomenezes]

Hello All,

I'm sorry if this is such a novice problem, but I'm having really trouble wiht it.

My application executes database operations by using a separated thread, instead using the main thread. I read several comments about sharing data to different threads, so I decided to use a signal-slot mechanism to transfer a QList<QSqlRecord> from one thread to other.

When the other thread receives the record list, it stores the records (variant values) into a QTableWidget. The problem is that QTableWidget is not displaying the correct precision of doubles.

I have a previous application where I don't use threads, so I just set a QSqlQueryModel to a QTableView and all numeric values are correctly displayed.

Is there any simple solution to this problem?

Regards,
Antonio Menezes.

Hello!

Just to say I found a solution. I've used the setNumericalPrecisionPolicy method of QSqlDatabase. I guess in Qt 4.6.2 the default is not QSql::HighPrecision.
