    \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

    \brief The QtVariantPropertyManager class provides and manages QVariant based properties.
 
    QtVariantPropertyManager provides the addProperty() function which
    creates QtVariantProperty objects. The QtVariantProperty class is
    a convenience class handling QVariant based properties inheriting
    QtProperty. A QtProperty object created by a
    QtVariantPropertyManager instance can be converted into a
    QtVariantProperty object using the variantProperty() function.
 
    The property's value can be retrieved using the value(), and set
    using the setValue() slot. In addition the property's type, and
    the type of its value, can be retrieved using the propertyType()
    and valueType() functions respectively.
 
    A property's type is a QMetaType::QType enumerator value, and
    usually a property's type is the same as its value type. But for
    some properties the types differ, for example for enums, flags and
    group types in which case QtVariantPropertyManager provides the
    enumTypeId(), flagTypeId() and groupTypeId() functions,
    respectively, to identify their property type (the value types are
    QMetaType::Int for the enum and flag types, and QMetaType::UnknownType
    for the group type).
 
    Use the isPropertyTypeSupported() function to check if a particular
    property type is supported. The currently supported property types
    are:
 
    \table
    \header

    The attributes for a given property type can be retrieved using
    the attributes() function. Each attribute has a value type which
    can be retrieved using the attributeType() function, and a value
    accessible through the attributeValue() function. In addition, the
    value can be set using the setAttribute() slot.
 
    QtVariantManager also provides the valueChanged() signal which is
    emitted whenever a property created by this manager change, and
    the attributeChanged() signal which is emitted whenever an
    attribute of such a property changes.

    \since 4.4
 
    \brief The QtVariantEditorFactory class provides widgets for properties
    created by QtVariantPropertyManager objects.
 
    The variant factory provides the following widgets for the
    specified property types:
 
    \table
    \header
        \li Property Type
        \li Widget
    \row
        \li \c int
        \li QSpinBox
    \row
        \li \c double
        \li QDoubleSpinBox
    \row
        \li \c bool
        \li QCheckBox
    \row
        \li QString
        \li QLineEdit
    \row
        \li QDate
        \li QDateEdit
    \row
        \li QTime
        \li QTimeEdit
    \row
        \li QDateTime
        \li QDateTimeEdit
    \row
        \li QKeySequence
        \li customized editor
    \row
        \li QChar
        \li customized editor
    \row
        \li \c enum
        \li QComboBox
    \row
        \li QCursor
        \li QComboBox
    \endtable
 
    Note that QtVariantPropertyManager supports several additional property
    types for which the QtVariantEditorFactory class does not provide
    editing widgets, e.g. QPoint and QSize. To provide widgets for other
    types using the variant approach, derive from the QtVariantEditorFactory
    class.
