I have following enum class:

#ifndef UEPROTOCOLCOMMANDS_H
#define UEPROTOCOLCOMMANDS_H

enum class UeProcotolCommand
{
    INVALID_COMMAND=0x0000000000000000,

    SERVER_GET_CLIENTS_VERSIONS=0x0000000000000001,
    SERVER_CONNECTION_RESET=0x0000000000000002,

    CLIENT_GET_DATABASE_CREDENTIALS=0x1000000000000001,
    CLIENT_DISCOVER_COMM_SERVER=0x1000000000000002
};   // UeProtocolCommands

#endif // UEPROTOCOLCOMMANDS_H

and it generates following error:

I need to tell to compiler that enum elements are of type quint64, not the default int. How?
