## Detailed Description

The TQSqlSelectCursor class provides browsing of general SQL SELECT statements.

TQSqlSelectCursor is a convenience class that makes it possible to display result sets from general SQL `SELECT` statements in data-aware TQt widgets. TQSqlSelectCursor is read-only and does not support `INSERT`, `UPDATE` or `DELETE` operations.

Pass the query in at construction time, or use the TQSqlSelectCursor::exec() function.

Example:

        ...
        TQSqlSelectCursor* cur = new TQSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
        TQDataTable* table = new TQDataTable( this );
        table->setSqlCursor( cur, TRUE, TRUE );
        table->refresh();
        ...
        cur->exec( "SELECT * FROM books" );
        table->refresh();
        ...
