@short Property.
It includes support for TQStringList properties, an i18n'ed label and stores an old value to allow undo.
Contains name, type and value.
Type can be one of predefined types (including standard @ref TQVariant types) by @ref PropertyLib::Property::PropertyType
enum or custom user type. User defined types should have values more than 3000.
Value is a @ref TQVariant.
Property can optionally have a list of possible values.
In that case use @ref ValueFromList type and valueList member.
Use @ref description for i18n'ed label.
Examples:
creating property:
\code
Property *property = new Property(String, name, description, value)
\endcode
using convenience constructor to create property of ValueFromList type:
\code
Property *property = new Property(name, possibleValuesList, description, value);
\endcode
