    \brief The QtIntPropertyManager provides and manages int properties.

    An int property has a current value, and a range specifying the
    valid values. The range is defined by a minimum and a maximum
    value.

    The property's value and range can be retrieved using the value(),
    minimum() and maximum() functions, and can be set using the
    setValue(), setMinimum() and setMaximum() slots. Alternatively,
    the range can be defined in one go using the setRange() slot.

    In addition, QtIntPropertyManager 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 values.

    \brief The QtDoublePropertyManager provides and manages double properties.

    A double property has a current value, and a range specifying the
    valid values. The range is defined by a minimum and a maximum
    value.

    The property's value and range can be retrieved using the value(),
    minimum() and maximum() functions, and can be set using the
    setValue(), setMinimum() and setMaximum() slots.
    Alternatively, the range can be defined in one go using the
    setRange() slot.

    In addition, QtDoublePropertyManager 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 values.

    \brief The QtBoolPropertyManager class provides and manages boolean properties.

    The property's value can be retrieved using the value() function,
    and set using the setValue() slot.

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

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