/*!
    \qmlclass ContentWrapper QFxContentWrapper
    \ingroup group_utility
    \brief ContentWrapper provides a component which contains content.
    \inherits Item

    In some cases the content of a component is not defined by the component itself.
    For example, the items placed in a group box need to be specified external to
    group box component definition itself.
    In cases like these \l Content can be used to specify at what location in the component
    the content should be placed. It is used in conjuntion with the \e content property of
    ContentWrapper: any items listed as content will be placed in the location
    specified by Content.  The component containing the Content must be of type
    ContentWrapper.

    GroupBox component definition:
    \quotefile doc/src/snippets/declarative/GroupBox.qml

    \bold Note that in the above component definition ContentWrapper's \e children
    property is specified explicitly since \e content is the default property.

    Component use:
    \table
    \row \o \image content.png
    \o \quotefile doc/src/snippets/declarative/content.qml
    \endtable
