QSysInfo Class Reference
^{^{[QtCore module]}}

The QSysInfo class provides information about the system. More...

 #include <QSysInfo>

List of all members, including inherited members

Public Types

enum Endian { BigEndian, LittleEndian, ByteOrder }
enum MacVersion { MV_9, MV_10_0, MV_10_1, MV_10_2, ..., MV_LEOPARD }
enum Sizes { WordSize }
enum WinVersion { WV_32s, WV_95, WV_98, WV_Me, ..., WV_CE_based }

Static Public Members

const MacVersion MacintoshVersion
const WinVersion WindowsVersion

Detailed Description

The QSysInfo class provides information about the system.

WordSize specifies the size of a pointer for the platform on which the application is compiled.
ByteOrder specifies whether the platform is big-endian or little-endian.
WindowsVersion specifies the version of the Windows operating system on which the application is run (Windows only)
MacintoshVersion specifies the version of the Macintosh operating system on which the application is run (Mac only).

Some constants are defined only on certain platforms. You can use the preprocessor symbols Q_WS_WIN and Q_WS_MAC to test that the application is compiled under Windows or Mac.

Member Type Documentation

enum QSysInfo::Endian

Constant	Value	Description
`QSysInfo::BigEndian`	`0`	Big-endian byte order (also called Network byte order)
`QSysInfo::LittleEndian`	`1`	Little-endian byte order
`QSysInfo::ByteOrder`	`<platform-dependent>`	Equals BigEndian or LittleEndian, depending on the platform's byte order.

enum QSysInfo::MacVersion

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

Constant	Value	Description
`QSysInfo::MV_9`	`0x0001`	Mac OS 9 (unsupported)
`QSysInfo::MV_10_0`	`0x0002`	Mac OS X 10.0 (unsupported)
`QSysInfo::MV_10_1`	`0x0003`	Mac OS X 10.1 (unsupported)
`QSysInfo::MV_10_2`	`0x0004`	Mac OS X 10.2 (unsupported)
`QSysInfo::MV_10_3`	`0x0005`	Mac OS X 10.3
`QSysInfo::MV_10_4`	`0x0006`	Mac OS X 10.4
`QSysInfo::MV_10_5`	`0x0007`	Mac OS X 10.5
`QSysInfo::MV_Unknown`	`0x0000`	An unknown and currently unsupported platform
`QSysInfo::MV_CHEETAH`	`MV_10_0`	Apple codename for MV_10_0
`QSysInfo::MV_PUMA`	`MV_10_1`	Apple codename for MV_10_1
`QSysInfo::MV_JAGUAR`	`MV_10_2`	Apple codename for MV_10_2
`QSysInfo::MV_PANTHER`	`MV_10_3`	Apple codename for MV_10_3
`QSysInfo::MV_TIGER`	`MV_10_4`	Apple codename for MV_10_4
`QSysInfo::MV_LEOPARD`	`MV_10_5`	Apple codename for MV_10_5

enum QSysInfo::Sizes

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

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

enum 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:

Constant	Value	Description
`QSysInfo::WV_32s`	`0x0001`	Windows 3.1 with Win 32s
`QSysInfo::WV_95`	`0x0002`	Windows 95
`QSysInfo::WV_98`	`0x0003`	Windows 98
`QSysInfo::WV_Me`	`0x0004`	Windows Me

NT-based versions:

Constant	Value	Description
`QSysInfo::WV_NT`	`0x0010`	Windows NT
`QSysInfo::WV_2000`	`0x0020`	Windows 2000
`QSysInfo::WV_XP`	`0x0030`	Windows XP
`QSysInfo::WV_2003`	`0x0040`	Windows Server 2003
`QSysInfo::WV_VISTA`	`0x0080`	Windows Vista

CE-based versions:

Constant	Value	Description
`QSysInfo::WV_CE`	`0x0100`	Windows CE
`QSysInfo::WV_CENET`	`0x0200`	Windows CE .NET

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

Constant	Value	Description
`QSysInfo::WV_DOS_based`	`0x000f`	MS-DOS-based version of Windows
`QSysInfo::WV_NT_based`	`0x00f0`	NT-based version of Windows
`QSysInfo::WV_CE_based`	`0x0f00`	CE-based version of Windows

Member Variable Documentation
