How to get value from everywhere

[wirasto]

I'm so impressed with QSqlDatabase. If I set like this..

QSqlDatabase db=QSqlDatabase::addDatabase(...);
db.setHostName("abc");

QSqlDatabase db=QSqlDatabase::addDatabase(...);
db.setHostName("abc");

To copy to clipboard, switch view to plain text mode 

I can get value "abc" in everywhere with

qDebug() << QSqlDatabase::database().hostName()

qDebug() << QSqlDatabase::database().hostName()

To copy to clipboard, switch view to plain text mode 

How to create like that...?

if you specified the name for connection in QSqlDatabase::addDatabase then you should use this name when using QSqlDatabase::database.

I think you are looking for a Singleton pattern.
