Using QDataBrowser

[Lebowski]

I need some help with QDataBrowser object. I want to set it up manually (without designer's wizard).

/* 'browser' is of type QDataBrowser, 
 'selected_tabel' is of type QString */
 
base = QSqlDatabase::database(); 
filter = "SELECT * FROM " + selected_tabel;
QSqlCursor curs =  QSqlCursor (selected_tabel, TRUE, base);
 
browser->setSqlCursor (&curs, FALSE);
browser->setFilter (filter);
browser->refresh();

/* 'browser' is of type QDataBrowser, 
 'selected_tabel' is of type QString */

base = QSqlDatabase::database(); 
filter = "SELECT * FROM " + selected_tabel;
QSqlCursor curs =  QSqlCursor (selected_tabel, TRUE, base);

browser->setSqlCursor (&curs, FALSE);
browser->setFilter (filter);
browser->refresh();

What am I missing? It compiles normally but I get blank data browser. How do I get fields and data from database? Connection is definitelly working as I have no problems showing same data in a table.
