class CContactItemField : public CBase

/** A field in a contact item.

Fields are grouped into a field set (CContactItemFieldSet), which is owned by 

the contact item.

The contact item field stores the field data. The data may be text, a date/time 

value, or an agent, as indicated by the storage type (TStorageType). The storage 

type is also owned by the field. Note that numeric field data is not supported. 

All numbers, for instance telephone or fax numbers are stored as text.

Fields also have a content type, attributes and a label. The label is a string 

which identifies the field to a user e.g. First name, Last name.

The following attributes are supported: 

- hidden: the field is not displayed if the view definition masks hidden 

fields

- disabled: the field cannot be deleted from the original template and thus 

is marked as disabled

- read only: the field cannot be written to

- synchronise: used by Connectivity applications; set by default for all 

contact item fields

- user added: the field was added by the user and was not taken from the 

template

- template: indicates that the field is part of a template. Template fields 

differ from other fields in that they are persisted when they do not contain 

any data.

- speed dial: the field contains a telephone number which maps to one of 

the nine possible speed dial positions.

These attributes can be set using member functions of this class, but they 

are normally set automatically by other functions, for instance when 

setting a speed dial field, CContactDatabase automatically sets the field's 

speed dial attribute.
