| Цитата(andrew_121 @ 14.2.2010, 13:37) | попробуйте QSQLITE
если заработает, то понятно что с плагином разбираться нужно.
кстати, откуда брали qsqlmysql4.dll ? по умолчанию он не поставляется с Qt.

пишет тоже самое:
| Код |
QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: avaiable drivers:
QSqlDatabase: an instance of QCoreApplication is required for
loading driver plugins

в plugins\sqldrivers по умолчанию лежат эти файлы:
qsqlite4.dll
qsqlmysql4.dll
qsqlodbc4.dll
qsqlpsql4.dll
в example есть пример:
работает и не понятно к какой базе он подключается.
