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.

enum QSysInfo::Endian

КонстантаЗначениеОписание
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.

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.

enum QSysInfo::Sizes

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

КонстантаЗначениеОписание
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:
