QT数据库QSQLITE [复制链接]

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
    db.setDatabaseName(":memory:");
    if (!db.open()) {
        QMessageBox::critical(0, qApp->tr("Cannot open database"),
            qApp->tr("Unable to establish a database connection.\n"
                    "This example needs SQLite support. Please read "
                    "the Qt SQL driver documentation for information how "
                    "to build it.\n\n"
                    "Click Cancel to exit."), QMessageBox::Cancel);
        return false;
    }
在connection中有这么一段,但database:QSQLITE在哪呀?怎么找不到.

你这段是QT的例子代码吧！
db.setDatabaseName(":memory:");
已经表示是内存数据库，你能不能好好去看看QT的技术文档特别是类QSqlDatabase那部分阿
