Detailed Description

This is the base abstract class for state and transition attributes.

Attributes are intented to be contained in IAttributeContainer-s. Attributes must subclass IAttribute and implement asString(), setValue(). New Attribute sub-types should be added to the AttributeType enum.

Generally, a view can query attribute containers for attributes, then query attributes for their values using asString(), without checking the type.

An subclass of IAttribute may override the the setValue() method to provide native type parameters, for example, from the TransitionPositionAttribute subclass:

        virtual void    setValue(const QString position)  ;
        void            setValue(const int w,const int h);
        void            setValue(const QPointF s);
