[править] QSysInfo Class Reference
[модуль QtCore ]
The QSysInfo class provides information about the system. Далее...

[править] Подробное описание
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.
See also QLibraryInfo.
[править] Описание типов
[править] enum QSysInfo::Endian
| Константа | Значение | Описание |
|---|---|---|
| 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. |
[править] 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.
| Константа | Значение | Описание |
|---|---|---|
| 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_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 |

[править] enum QSysInfo::Sizes
This enum provides platform-specific information about the sizes of data structures used by the underlying architecture.
| Константа | Значение | Описание |
|---|---|---|
| QSysInfo::WordSize | ( sizeof( void * ) <<3 ) | The size in bits of a pointer for the platform on which the application is compiled (32 or 64). |
[править] 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:
| Константа | Значение | Описание |
|---|---|---|
| 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:
| Константа | Значение | Описание |
|---|---|---|
| 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:
| Константа | Значение | Описание |
|---|---|---|
| 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:
| Константа | Значение | Описание |
|---|---|---|
| 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 |
