/**
    \class QtSizePropertyManager

    \brief The QtSizePropertyManager provides and manages QSize properties.

    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
    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 size property also has a range of valid values defined by a
    minimum size and a maximum size. These sizes can be retrieved
    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
    which is emitted whenever a property created by this manager
    changes, and the rangeChanged() signal which is emitted whenever
    such a property changes its range of valid sizes.

/**
    \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.
