14\li The \l{QmlGlobalQtObject}{Qt object}: A QML object that offers helper methods
15 and properties specific to the QML environment.

17 \l {Qt::}{QT_TRANSLATE_NOOP()}, \l {Qt::}{QT_TRID_NOOP()} functions:
18 QML functions that let you translate \l{Mark Strings for Translation}
19 {strings} and \l{Mark Translatable Data Text Strings}{string literals} in the
20 QML environment.
21\li gc() function: A QML function that manually triggers garbage collection.
