  \title QML Elements
  \brief A listing of standard QML elements.

These are the functionally grouped lists of QML elements as part of
\l{Qt Quick}.

Elements are declared with the their name and two curly braces. Elements may
be nested in elements, thereby creating a parent-child relationship between the
two elements.

To see the QML elements listed by functional area, see the
\l{Groups Of Related QML Elements} page.
