* Unlike in the first kab version, the configuration file and the data file are * different objects of QConfigDB. This way, the data file is no more limited * to the one in the users KDE directory, multiple files may be used. Different * instances of the program may use different data files. Read-only addressbook * files are possible.
* Only one configuration file per user is used, it is
* ~/.kde/share/apps/kab/kab.config
* A standard user file will automatically be created as
* ~/.kde/share/apps/kab/addressbook.kab
* File changes are watched by the program, so every instance will automatically * update its database on a change of the opened file. * * \par The KDE addressbook database system * kab manages entries in address databases based on a key system where the * program assigns keys to added entries. These keys are not reused in one file, * so API users can rely on a key to be unique and identifying until the entry * is deleted by the user (this is a change to kab 1 that reused freed entry * keys). Of course, in different files a key might be used twice.
* The keys are objects of the type KabKey and define the section in the * addressbook database where the entry is stored (see QConfigDB * reference). Keys tqinvalidate on file changes, so keep track of the * signal ::changed.
* kab watches file changes. If the opened file changes on disk, it is * automatically reloaded and ::changed() is emitted. * * \par The users standard personal information database * kab assumes that it is able to read and write the users standard database. * This way, the kab application itselfes and applications using the KabAPI can * rely on the possibility to add entries to this database (from a browser, for * example). Usually, this file is opened automatically by the constructor. * If - for what reason ever - the file cannot be either created or read, kab * will still start up, but no database operation will work until the user * opened a file. In this case, the method ::getState will return * ::PermDenied. In general it is a good idea to check the return value of the * ::getState method before using KabAPI operations. * * \par The mirror map * The entries are stored in the QConfigDB object ::data which represents the * currently opened file. In every file there is a section with the name * entries that contains a subsection for every entry. The name of * the subsection is the key of the entry.
* When retrieving the sections, they are ordered alphabetically by their keys. * This is not what users expect, since the keys show the insertion order of * the entries, not more and not less. Additionally the displaying order should * be configurable.
* That is why kab uses a STL map to map its entry keys to user * (at least programmer...) defined descriptors. Usually, the descriptors are * created as a combination of the entry data, and then displayed in aphabetical * order in the selector combobox. This map is called the mirror map throughout * the documentation. It is created or updated every time the database changes. * Thus the way to find a special entry is:

the user selects an item in the selector combo box, returning its * index,
the index is used to find the key of the entry in the mirror map,
and finally the entry is retrieved by its key from the database.

* To modify the sorting order, the way to create the entry descriptors in the * mirror map nedds to be changed. * * \par The view * If you display an AddressBook object (that is a derived TQFrame), * it may show an entry * of the database that you might select. The entry you hand over to the method * ::displayEntry does not need to be contained in the currently loaded file. * This way you may integrate views of * the users addressbook database in your own application as a simple widget * type. To allow the user to * navigate through the database, you might want to show kab's own toolbar in * your mainwindow (or whereever). (The toolbar is not implemented by now).
* Some parts of the AddressBook widget are \e interactive, that means they are * displayed as transparent KURLLabels that react when the user clicks on it. * These interactive parts have to be enabled by calling setInteractiveMode(). */ class AddressBook : public TQFrame { // ############################################################################ Q_OBJECT // ---------------------------------------------------------------------------- public: /** * The return values of some AddressBook member functions are #ErrorCode * values. */ enum ErrorCode { NoError, /** No error, the operation did not fail. */ PermDenied, /**< Access permissions for the operation are not available. */ Locked, /**< An writing operation on a locked file was requested. */ Rejected, /**< The requested operation has been rejected by the user. */ NoSuchEntry, /**< An entry has been referenced using a unknown key. */ NoEntry, /**< You tried to retrieve an entry but there is none. */ NoFile, /**< No file has been loaded by now. */ NoSuchFile, /**< A filename could not be found on the filesystem. */ InternError, /**< A error in kab's internal logic occurred. */ OutOfRange, /**< An index value was out of the allowed range. */ NoSuchField, /**< You queried a field that does not exist. */ NotImplemented /**< The requested operation is not implemented. */ }; /** * Some predefined telephone types.

This class is intended to handle hierarchical structures. * Thus, kab is able to create human readable but still deep and complex * data files. This paragraph describes the overall structure of the * files, the next two deal with special parts of it.
* First of all, kab II data files (that usually end with \c .kab, while in * kab 1 the fixed file name was \c addressbook.database) have two main * sections (see the documentation of the QConfigDB and Section classes), * one is called \c config, it contains different file specific * configuration settings like the last displayed entry, and one section * called \c entries that in turn contains a subsection for each entry in * the database file. The keys of this subsections are the literal strings * that are used in the KabKey class in the member KabKey::key. Each entry * subsection has some key-value-pairs described below and another * subsection "addresses" with one or more addresses in it. See the * following example for a kab II data file (without any key-value-pairs): *

   *  [config]
   *  [END]
   *  [entries]
   *     [1] (the first entry with literal key "1")
   *       [addresses]
   *         [1] (the first address, addresses are enumerated)
   *         [END]
   *         [2] (the second address)
   *         [END]
   *         ... (more addresses may follow)
   *       [END]
   *     [END]
   *     [2] (the second entry)
   *       [addresses]
   *         [1]
   *         [END]
   *       [END]
   *     [END]
   *     ... (more entries may follow)
   *  [END]

* * \par The fields an entry contains * An entry contains all settings that are expected to be unique for all * addresses directly as key-value-pairs. Everything that is part of a * specific address of this person is part of an object of the member list * \c addresses referenced in the next paragraph.
* The keys defined directly in the entry sections are:

title
: The title of that person.
rank
: A possible military rank of that person.
fn
: The formatted name. If it is not empty, it replaces the * standard combination of the other name fields in the address * display.
nameprefix
: A possible name prefix.
firstname
: The first name.
middlename
: The middle name.
lastname
: The last name.
birthday
: The birthday (a TQDate).
comment
: A free form comment.
talk
: The talk addresses (a string list).
emails
: The email addresses (a string list).
keywords
: A list of free-form keywords.
telephone
: A list of telephone numbers in a special format.
URLs
: A list of internet addresses.
user_1
: The first user-declared data field.
user_2
: The second user-declared data field.
user_3
: The third user-declared data field.
user_4
: The fourth user-declared data field.

* See the next section for a description of the addresses subsections. * * \par The fields of the addresses subsections * The section for each entry contains a subsection \c addresses with * in turn a subsection for each address. The addresses are enumerated * in the order they are inserted, their keys are the numbers of * inserting converted to a string.
* The keys defined in an address subsection are:

headline: A headline shown for the address.
position: The position of the person.
org: The organization.
orgunit: The organizational unit.
orgsubunit: The organizational subunit.
role: The role of the person.
deliverylabel: A label for delivering to this address.
address: The street, house no., flat etc line.
zip: A zip or postal code.
town: The town the person lives in in this address.
country: The country for federal states.
state: The state for federal states.

* * \par The local configuration section * For each kab II database file there are some settings that apply * only to the file itselfes, not to all kab databases the user works * with. These settings are called the local configuration. The settings * are stored in the \c config section of the local file. The following * keys are declared in this section:

user_1: The \e name of the first user-declared field.
user_2: The \e name of the second user-declared field.
user_3: The \e name of the third user-declared field.
user_4: The \e name of the fourth user-declared field.
