Detailed Description

The QSysInfo class provides information about the system.

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::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).

enum QSysInfo::SymbianVersion

This enum provides symbolic names for the various versions of the Symbian operating system. On Symbian, the QSysInfo::symbianVersion() function gives the version of the system on which the application is run.

ConstantValueDescription
