Storing and Retrieving a QFlags

[darkadept]

I want to be able to store a QFlags variable in a database and then retrieve it later on.

I have an enum of weekdays like this:

enum Weekday {
  NoWeekday = 0x0,
  Monday = 0x1,
  Tuesday = 0x2,
  Wednesday = 0x4,
  Thursday = 0x8,
  Friday = 0x16,
  Saturday = 0x32,
  Sunday = 0x64
};
Q_DECLARE_FLAGS(Weekdays, Weekday);
 
class MyClass
{
public:
  Weekdays days;
  void save() {
    days = Monday | Thursday;
    //I can convert 'days' into an int no problem here
  }
  void load() {
    //How do I convert my stored int back into a Weekdays QFlags?
  }
};

enum Weekday {
  NoWeekday = 0x0,
  Monday = 0x1,
  Tuesday = 0x2,
  Wednesday = 0x4,
  Thursday = 0x8,
  Friday = 0x16,
  Saturday = 0x32,
  Sunday = 0x64
};
Q_DECLARE_FLAGS(Weekdays, Weekday);

class MyClass
{
public:
  Weekdays days;
  void save() {
    days = Monday | Thursday;
    //I can convert 'days' into an int no problem here
  }
  void load() {
    //How do I convert my stored int back into a Weekdays QFlags?
  }
};

I've looked through the docs on QFlags and QVariant but can't find anything pertinent.

I'm using my own enum instead of Qt::dayOfWeek because I need to have an OR'd combination of weekdays instead of just a single one.

Another way I thought of doing this is with a QBitArray the way Kde4 does it in their libkdepim library but I don't know how to store (or serialize) a QBitArray.

I'm using QSqlQuery to select and insert my data into a database.
