Dear all,
I am using Qt Embedded 4.6.3/QWS on embedded linux.
For displaying values from a sqlite database I am using a combination of
QTableView and QSqlTableModel. As per the documentation the function
QSqlTableModel::select() does not load more than 255? rows from the
database and the following rows are being loaded transparently once they
are needed, right?
However, loading 255 rows from the database still takes some time on my
system (~6 seconds). I would rather like to limit the local buffer size to
e.g. 30 lines as there is not more space on the display anyway.
Is there a way to configure the size of this local buffer for
QSqlTableModel?
Mit freundlichen Grüßen / Best regards
Markus Franke
