Subject: QSqlTM: add reimplemented record() method
X-Git-Tag: v5.0.0-beta1~753
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fbf010a26617b3986e9a76bd9c004403aebfcdc2;p=profile%2Fivi%2Fqtbase.git

QSqlTM: add reimplemented record() method

QSqlQueryModel::record(row) populates the record it returns with values
from virtual data(), so the values themselves can be supplied by
QSqlTableModel. However, it is also desirable to be able to interrogate
QSqlTableModel for the actual current record in its cache, including
properties such as the generated flag.
