 A property browser is a widget that enables the user to edit a344#    given set of properties. Each property is represented by a label345#    specifying the property's name, and an editing widget (e.g. a line346#    edit or a combobox) holding its value. A property can have zero or347#    more subproperties.348#349#    QtGroupBoxPropertyBrowser provides group boxes for all nested350#    properties, i.e. subproperties are enclosed by a group box with351#    the parent property's name as its title. For example:352#353#    \image qtgroupboxpropertybrowser.png354#355#    Use the QtAbstractPropertyBrowser API to add, insert and remove356#    properties from an instance of the QtGroupBoxPropertyBrowser357#    class.
