Detailed Description
A class break corresponds to a range of values for an attribute field. A list of class break instances are maintained in the ClassBreakListModel. When the class breaks renderer is used to display a layer, the symbol used for a feature is determined by the value in a selected attribute. When the value falls within a class break, the corresponding symbol and label display.
Class breaks contain this information: Value, range, name, and description, as well as the label and symbol to display for features that contain attribute values within this class break.
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
