QSysInfo Class Reference
^{[QtCore module]}

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

Types

• enum Endian { BigEndian, LittleEndian, ByteOrder }
• enum Sizes { WordSize }
• enum WinVersion { WV_32s, WV_95, WV_98, WV_Me, ..., WV_CE_based }

Methods

• __init__ (self)
• __init__ (self, QSysInfo)

Static Members

• WinVersion WindowsVersion

• 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.

Type Documentation

QSysInfo.Endian

QSysInfo.Sizes

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

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:

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

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

CE-based versions:

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

QSysInfo.__init__ (self)

QSysInfo.__init__ (self, QSysInfo)

Member Documentation

WinVersion WindowsVersion

This member should be treated as a constant.

This variable holds the version of the Windows operating system on which the application is run (Windows only).
