The 128bit value + of an UUID is generated by an algorithm that guarantees a value that is unique in time and space. + + In Qt, UUIDs are wrapped by the QUuid struct which provides convenience functions for comparing and coping + this value. The QUuid struct is used in Qt's component model to identify interfaces. Most platforms provide a tool to + generate new UUIDs (uuidgen, guidgen), and the Qt distribution includes a graphical tool \e quuidgen that generates + the UUIDs in a programmer friendly format. + + \sa QUnknownInterface +*/ + +/*! + \fn QUuid::QUuid() + + Creates the null UUID {00000000-0000-0000-0000-000000000000}. +*/ + +/*! + \fn QUuid::QUuid( uint l, ushort w1, ushort w2, uchar b1, uchar b2, uchar b3, uchar b4, uchar b5, uchar b6, uchar b7, uchar b8 ) + + Creates an UUID with the value specified by the parameters, \a l, \a + w1, \a w2, \a b1, \a b2, \a b3, \a b4, \a b5, \a b6, \a b7, \a b8. + + Example: + \code + // {67C8770B-44F1-410A-AB9A-F9B5446F13EE} + QUuid IID_MyInterface( 0x67c8770b, 0x44f1, 0x410a, 0xab, 0x9a, 0xf9, 0xb5, 0x44, 0x6f, 0x13, 0xee ) + \endcode +*/ + +/*! + \fn QUuid::QUuid( const QUuid &orig ) + + Creates a copy of the QUuid \a orig. +*/ +#ifndef QT_NO_QUUID_STRING +/*! + Creates a QUuid object from the string \a text.
