/**
    \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.

    \brief The QtCursorPropertyManager provides and manages QCursor properties.

    A cursor property has a current value which can be
    retrieved using the value() function, and set using the setValue()
    slot. In addition, QtCursorPropertyManager provides the
    valueChanged() signal which is emitted whenever a property created
    by this manager changes.
