\qmltype SystemInformation \inherits QtObject \inqmlmodule QtCore
- Since
- 6.4
Provides information about the system.
The SystemInformation singleton type provides information about the system, using a similar API to \l QSysInfo, where each function in QSysInfo is available as a property:
\qml if (SystemInformation.wordSize === 64) { console.log("64 bit") } else { console.log("32 bit") }
if (SystemInformation.byteOrder === SystemInformation.Little) { console.log("Little endian") } else { console.log("Big endian") }
console.log("Currently running on " + SystemInformation.prettyProductName) \endqml
