QString problem...

[wysota]

What exactly "doesn't work"?

[Nefastious]

@wysota

it simply doesn't open up any databases, when requested to do so

@at the other guys
will try qdebug and then post another reply with the results

[Nefastious]

well I did play with qDebug for a while it tells me that well, here are the results:

we are in openfile() now
database opened
path not empty

one thing I added qDebug() << "database opened"
as part of that if that tests if the database is opened (in loaddatabase() ),
so aparently the problem doesn't lie in the path String.

Any ideas where it might lie?

If you need any code I will show it upon request

Thanks in advance

Did you try asking the database what the problem was?
QSqlDatabase::lastError()

[Nefastious]

By using

qDebug() << db.lastError();

qDebug() << db.lastError();

To copy to clipboard, switch view to plain text mode 

I get the following:

QSqlError(-1, "", "")

What does this mean?

[wysota]

It means there is no error in the database object. How do you know the database failed to open?

[Nefastious]

Well,

there is a model connected to the database and then a TableView connected to the model, and the View remains blank after I supposedly load the database...


Any ideas?

It doesn't mean the database failed to open!

What do QSqlDatabase::open() and QSqlDatabase::isOpen() return?

[Nefastious]

true on both

so we can assume that the problem doesn't lie on the database object itself, but where could it lie? Any ideas?

[wysota]

The query is probably incorrect or the table is empty. Check the last error of the model.
