Hi,
my C++ code makes heavy use of quite simple enums which are defined in some
namespace, outside of any class (and therefore also outside of any class
which derives from QObject). It's done like this:
namespace Imap {
typedef enum { FLAG_ADD, FLAG_REMOVE } FlagsOperation;
}
I also have some classes derived from QObject which accept these enums as
an argument. This works just fine from C++. I would like to export these
methods to QML, but I'm having trouble coming up with a scheme which will
allow my QML code to access these enums.
The documentation [1] says that "C++ signals and methods with
enumeration-type parameters can be used from QML provided that the
enumeration and the signal or method are both declared within the same
class, or that the enumeration value is one of those declared in the Qt
Namespace.". That's clearly not the case for these existing methods, and
the idea of changing our C++ code in order to accommodate a random QML
requirement looks rather weird.
What would be the easiest way of making this work? A typedef? Or some hack
to register that type through qmlRegisterType?
With kind regards,
Jan
