template<typename T >
QList< T >	findChildren (Qt::FindChildOptions options=Qt::FindChildrenRecursively) const
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

bool	setProperty (const char *name, const QVariant &value)
	Sets the value of the object's name property to value.

bool	setProperty (const char *name, QVariant &&value)

QVariant	property (const char *name) const
	Returns the value of the object's name property.

QList< QByteArray >	dynamicPropertyNames () const

QBindingStorage *	bindingStorage ()

const QBindingStorage *	bindingStorage () const

QObject *	parent () const
	Returns a pointer to the parent object.

bool	inherits (const char *classname) const
	Returns `true` if this object is an instance of a class that inherits className or a QObject subclass that inherits className; otherwise returns `false`.

Constructor & Destructor Documentation

◆ QQmlSystemInformation()

QT_BEGIN_NAMESPACE QQmlSystemInformation::QQmlSystemInformation ( QObject * parent = nullptr )

explicit

\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
