    \brief The QtEnumPropertyManager provides and manages enum properties.

    Each enum property has an associated list of enum names which can
    be retrieved using the enumNames() function, and set using the
    corresponding setEnumNames() function. An enum property's value is
    represented by an index in this list, and can be retrieved and set
    using the value() and setValue() slots respectively.

    Each enum value can also have an associated icon. The mapping from
    values to icons can be set using the setEnumIcons() function and
    queried with the enumIcons() function.

    In addition, QtEnumPropertyManager provides the valueChanged() signal
    which is emitted whenever a property created by this manager
    changes. The enumNamesChanged() or enumIconsChanged() signal is emitted
    whenever the list of enum names or icons is altered.

    \brief The QtFlagPropertyManager provides and manages flag properties.

    Each flag property has an associated list of flag names which can
    be retrieved using the flagNames() function, and set using the
    corresponding setFlagNames() function.

    The flag manager provides properties with nested boolean
    subproperties representing each flag, i.e. a flag property's value
    is the binary combination of the subproperties' values. A
    property's value can be retrieved and set using the value() and

    by single int value - that's why it's possible to store up to
    32 independent flags in one flag property.

    The subproperties are created by a QtBoolPropertyManager object. This
    manager can be retrieved using the subBoolPropertyManager() function. In
    order to provide editing widgets for the subproperties in a
    property browser widget, this manager must be associated with an
    editor factory.

    In addition, QtFlagPropertyManager provides the valueChanged() signal

/**
    \class QtSizePolicyPropertyManager

    \brief The QtSizePolicyPropertyManager provides and manages QSizePolicy properties.

    A size policy property has nested \e horizontalPolicy, \e
    verticalPolicy, \e horizontalStretch and \e verticalStretch
    subproperties. The top-level property's value can be retrieved
    using the value() function, and set using the setValue() slot.

    The subproperties are created by QtIntPropertyManager and QtEnumPropertyManager
    objects. These managers can be retrieved using the subIntPropertyManager()
    and subEnumPropertyManager() functions respectively. In order to provide
    editing widgets for the subproperties in a property browser widget,
    these managers must be associated with editor factories.

    In addition, QtSizePolicyPropertyManager provides the valueChanged()
    signal which is emitted whenever a property created by this
    manager changes.

/**
    \fn void QtSizePolicyPropertyManager::valueChanged(QtProperty *property, const QSizePolicy &value)

    This signal is emitted whenever a property created by this manager
    changes its value, passing a pointer to the \a property and the
