详细描述

The QSysInfo class provides information about the system.

  • WordSize 指定用于在其中编译应用程序的平台指针大小。
  • ByteOrder 指定平台是大端在前还是小端在前。
  • 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.
