This is another one of those "which way is best" questions. I am wondering which is the best way to use named constant QStrings in a class. For example:

Qt Code: 
  1. class MyClass {
  2. public:
  3.   void doStuff() {
  4.     {
  5.       QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL", "MySpecialDbName");    
  6.       //do all sorts of database stuff here
  7.       db.close();
  8.     }
  9.     QSqlDatabase::removeDatabase("MySpecialDbName");    
  10.   }
  11. };
To copy to clipboard, switch view to plain text mode 

"MySpecialDbName" should be a named constant, right? Especially if doStuff() is complex or the call to removeDatabase() is done in another method etc.

One way I thought of is to use an enum and a function to translate the enum to a QString.
Qt Code: 
  1. enum MyStrings {
  2.   DbName,
  3.   SettingsGroup,
  4.   ProgramName
  5. };
  6. QString getMyString(MyStrings string) {
  7.   switch (string) {
  8.     case (DbName):
  9.       return QString("MySpecialDbName");
  10.     case (SettingsGroup):
  11.       return QString("my/config/db");
  12.     case (ProgramName):
  13.       return QString("My Program");
  14.     default:
  15.       return QString();
  16.   }
  17. }
To copy to clipboard, switch view to plain text mode 

Or even the enum as above and an array of QStrings or a QStringList.

Maybe I'm just being pedantic but I can't seem to find any examples of what other people do. And maybe it doesn't matter in the end anyway... but I figured I'd ask.
