QSysInfo.Endian

ConstantValueDescription
QSysInfo.BigEndian0Big-endian byte order (also called Network byte order)
QSysInfo.LittleEndian1Little-endian byte order
QSysInfo.ByteOrder<platform-dependent>Equals BigEndian or LittleEndian, depending on the platform's byte order.

QSysInfo.Sizes

This enum provides platform-specific information about the sizes of data structures used by the underlying architecture.

ConstantValueDescription
QSysInfo.WordSize( sizeof( void * ) <<3 )The size in bits of a pointer for the platform on which the application is compiled (32 or 64).

QSysInfo.WinVersion

This enum provides symbolic names for the various versions of the Windows operating system. On Windows, the QSysInfo.WindowsVersion variable gives the version of the system on which the application is run.

MS-DOS-based versions:

ConstantValueDescription
QSysInfo.WV_32s0x0001Windows 3.1 with Win 32s
QSysInfo.WV_950x0002Windows 95
QSysInfo.WV_980x0003Windows 98
QSysInfo.WV_Me0x0004Windows Me

NT-based versions (note that each operating system version is only represented once rather than each Windows edition):

ConstantValueDescription
QSysInfo.WV_NT0x0010Windows NT (operating system version 4.0)
QSysInfo.WV_20000x0020Windows 2000 (operating system version 5.0)
QSysInfo.WV_XP0x0030Windows XP (operating system version 5.1)
QSysInfo.WV_20030x0040Windows Server 2003, Windows Server 2003 R2, Windows Home Server, Windows XP Professional x64 Edition (operating system version 5.2)
QSysInfo.WV_VISTA0x0080Windows Vista, Windows Server 2008 (operating system version 6.0)
QSysInfo.WV_WINDOWS70x0090Windows 7, Windows Server 2008 R2 (operating system version 6.1)

Alternatively, you may use the following macros which correspond directly to the Windows operating system version number:

ConstantValueDescription
QSysInfo.WV_4_0WV_NTOperating system version 4.0, corresponds to Windows NT
QSysInfo.WV_5_0WV_2000Operating system version 5.0, corresponds to Windows 2000
QSysInfo.WV_5_1WV_XPOperating system version 5.1, corresponds to Windows XP
QSysInfo.WV_5_2WV_2003Operating system version 5.2, corresponds to Windows Server 2003, Windows Server 2003 R2, Windows Home Server, and Windows XP Professional x64 Edition
QSysInfo.WV_6_0WV_VISTAOperating system version 6.0, corresponds to Windows Vista and Windows Server 2008
QSysInfo.WV_6_1WV_WINDOWS7Operating system version 6.1, corresponds to Windows 7 and Windows Server 2008 R2

CE-based versions:

ConstantValueDescription
QSysInfo.WV_CE0x0100Windows CE
QSysInfo.WV_CENET0x0200Windows CE .NET
QSysInfo.WV_CE_50x0300Windows CE 5.x
QSysInfo.WV_CE_60x0400Windows CE 6.x

The following masks can be used for testing whether a Windows version is MS-DOS-based, NT-based, or CE-based:

ConstantValueDescription
QSysInfo.WV_DOS_based0x000fMS-DOS-based version of Windows
QSysInfo.WV_NT_based0x00f0NT-based version of Windows
QSysInfo.WV_CE_based0x0f00CE-based version of Windows
