/**
 * @author Olivier Goffart <ogoffart @ kde.org>
 *
 * This class is used by the protocol plugins to add specific protocol fields in the add account wizard,
 * or in the account preferences. If the given account is 0L, then you will have to create a new account
 * in @ref apply().
 *
 * Each protocol has to subclass this class, and the protocol's edit account page MUST inherits from
 * TQWidget too.
 *
 * We suggest to put at least these fields in the page:
 *
 * - The User login, or the accountId. you can retrieve it from @ref Kopete::Account::accountId(). This
 *   field has to be marked as ReadOnly or shown as a label if the account already exists. Remember
 *   that accountId should be constant after account creation!
 *
 * - The password, and the remember password checkboxes.
 *
 * - The auto connect checkbox: use @ref Kopete::Account::excludeConnect() and
 *   @ref Kopete::Account::setExcludeConnect() to get/set this flag.
 *
 * You may add other custom fields, e.g. the nickname. To save or retrieve these settings use
 * @ref Kopete::ContactListElement::pluginData() with your protocol as plugin.
