    An int property has a current value, and a range specifying the

    A size property has nested \e width and \e height
    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 a QtIntPropertyManager object. This

    A size property also has a range of valid values defined by a

    using the minimum() and the maximum() functions, and set using the
    setMinimum() and setMaximum() slots. Alternatively, the range can
    be defined in one go using the setRange() slot.

    In addition, QtSizePropertyManager provides the valueChanged() signal

    \class QtRectPropertyManager

    \brief The QtRectPropertyManager provides and manages QRect properties.

    A rectangle property has nested \e x, \e y, \e width and \e height
    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 a QtIntPropertyManager object. This
    manager can be retrieved using the subIntPropertyManager() function. In
    order to provide editing widgets for the subproperties in a
    property browser widget, this manager must be associated with an
    editor factory.

    A rectangle property also has a constraint rectangle which can be
    retrieved using the constraint() function, and set using the
    setConstraint() slot.

    In addition, QtRectPropertyManager provides the valueChanged() signal
    which is emitted whenever a property created by this manager
    changes, and the constraintChanged() signal which is emitted
    whenever such a property changes its constraint rectangle.

    \class QtRectFPropertyManager

    \brief The QtRectFPropertyManager provides and manages QRectF properties.

    A rectangle property has nested \e x, \e y, \e width and \e height
    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 a QtDoublePropertyManager object. This
    manager can be retrieved using the subDoublePropertyManager() function. In
    order to provide editing widgets for the subproperties in a
    property browser widget, this manager must be associated with an
    editor factory.

    A rectangle property also has a constraint rectangle which can be
    retrieved using the constraint() function, and set using the
    setConstraint() slot.

    In addition, QtRectFPropertyManager provides the valueChanged() signal
    which is emitted whenever a property created by this manager
    changes, and the constraintChanged() signal which is emitted
    whenever such a property changes its constraint rectangle.

    \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.

    \class QtFlagPropertyManager

    \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
    setValue() slots respectively. The combination of flags is represented
    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
    which is emitted whenever a property created by this manager
    changes, and the flagNamesChanged() signal which is emitted
    whenever the list of flag names is altered.

    \class QtFontPropertyManager

    \brief The QtFontPropertyManager provides and manages QFont properties.

    A font property has nested \e family, \e pointSize, \e bold, \e
    italic, \e underline, \e strikeOut and \e kerning 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, QtEnumPropertyManager and
    QtBoolPropertyManager objects. These managers can be retrieved using the
    corresponding subIntPropertyManager(), subEnumPropertyManager() and
    subBoolPropertyManager() functions. In order to provide editing widgets
    for the subproperties in a property browser widget, these managers
    must be associated with editor factories.

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