Each Quark is unique but may change between runs. QueryQuark is a converter class for looking up but not allocating an ID. An id means the quark lookup failed. Quark is used for actions for which the id should live on While QueryQuark should be used for queries. ie. void set_data (const Quark&, void* data); void* get_data (const QueryQuark&); Constructor & Destructor Documentation Glib::QueryQuark::QueryQuark ( const GQuark&    q )  Glib::QueryQuark::QueryQuark ( const ustring&    s )  Glib::QueryQuark::QueryQuark ( const char*    s )  Glib::QueryQuark::~QueryQuark (   )  [inline] Member Function Documentation GQuark Glib::QueryQuark::id (   )  const [inline] Glib::QueryQuark::operator GQuark (   )  const [inline] Glib::QueryQuark::operator ustring (   )  const QueryQuark& Glib::QueryQuark::operator= ( const QueryQuark&    q )  Friends And Related Function Documentation bool operator!= ( const QueryQuark&    a, const QueryQuark&    b )  [related] bool operator== ( const QueryQuark&    a, const QueryQuark&    b )  [related] The documentation for this class was generated from the following file: quark.h
