    \brief The QtVariantProperty class is a convenience class handling

    QVariant based properties.

    QtVariantProperty provides additional API: A property's type,

    value type, attribute values and current value can easily be

    retrieved using the propertyType(), valueType(), attributeValue()

    and value() functions respectively. In addition, the attribute

    values and the current value can be set using the corresponding

    setValue() and setAttribute() functions.

    For example, instead of writing:

    \snippet doc/src/snippets/code/tools_shared_qtpropertybrowser_qtvariantproperty.cpp 0

    you can write:

    \snippet doc/src/snippets/code/tools_shared_qtpropertybrowser_qtvariantproperty.cpp 1

    QtVariantProperty instances can only be created by the

    QtVariantPropertyManager class.

    \sa QtProperty, QtVariantPropertyManager, QtVariantEditorFactory

    Do not use this constructor to create variant property instances;

    use the QtVariantPropertyManager::addProperty() function
