\class TQDataView tqdataview.h
\brief The TQDataView class provides read-only SQL forms.
\ingroup database
\mainclass
\module sql
This class provides a form which displays SQL field data from a
record buffer. Because TQDataView does not support editing it uses
less resources than a TQDataBrowser. This class is well suited for
displaying read-only data from a SQL database.
If you want a to present your data in an editable form use
TQDataBrowser; if you want a table-based presentation of your data
use TQDataTable.
The form is associated with the data view with setForm() and the
record is associated with setRecord(). You can also pass a
TQSqlRecord to the refresh() function which will set the record to
the given record and read the record's fields into the form.

name, and with widget flags \a fl.
