    \title Customizing Qt Quick Controls 2
    \brief A set of UI controls to create user interfaces in Qt Quick

    Qt Quick Controls consist of a hierarchy (tree) of items. In order to
    provide a custom look and feel, the default QML implementation of each
    item can be replaced with a custom one. The following snippets present
    the default implementations of various items. These can be used as a
    starting point to implement a custom look and feel.
