Detailed Description

Provides access to instant messenger programs which implement KDE's instant messanger interface KIMIface.

This class provides an easy-to-use interface to all running instant messengers or chat programs that implement KIMIface.

It works simultaneously with any running programs that implement the ServiceType DCOP/InstantMessenger.

IM-contacts are identified using unique identifier strings (UID) used by KDE's address book framework KABC. However the use of the address book API is optional, KIMProxy provides methods to fetch lists of available contact UIDs from the applications. If a UID is reachable with more than one program, KIMProxy aggregates the available information and presents the 'best' presence. For example, for a contact who can be seen to be Away in IRC on program A but Online using ICQ on program B, the information from program B will be used.

KIMProxy is designed for simple information in a wide number of cases, not for detailed messaging.

The class is implemented as a singleton, so whenever you need access to one of its methods, just retrieve the single instance using instance(). The following code snippet demonstrated how to send a message to all reachable IM-contacts:

 // get proxy instance
 KIMProxy* proxy = KIMProxy::instance();

 // check if there are suitable applications reachable
 if (!proxy->initialize()) return;

 QString message = "Hi!\nHow are you on this wonderful day?";

 // iterate over the list of reachable contacts
 QStringList reachableContacts = proxy->reachableContacts();
 for (QStringList::const_iterator it = reachableContacts.begin();
      it != reachableContacts.end(); ++it)
 {
       proxy->messageContact(*it, message);
 }

Note:
While it is possible to communicate with each of those application's by DCOP using KIMProxy has the advantage of communicating with all applications simultaneously and thus getting an augmented view of availability, capability and presence (online status) of IM-contacts.

KIMIface::protocols()

Definition at line 533 of file kimproxy.cpp.

QStringList KIMProxy::allContacts (  ) 

Obtain a list of IM-contacts known to IM-applications.

Returns a list of KABC UIDs gathered by merging the lists of each application the proxy can communicate with. The method uses cached information to make it fast and not require actually communicating with the applications every time it is called.

Returns:
a list of KABC UIDs known to any IM-application

KABC::Addressee::uid()

Definition at line 394 of file kimproxy.cpp.

bool KIMProxy::canReceiveFiles ( const QString &  uid  ) 

Indicate if a given contact can receive files.

If the given KABC UID is known to more than one IM-application the result of the application which has the best presence for the contact is taken. For example if a contact is Online on ICQ and Away on AIM, the value returned by the application providing ICQ is taken.

Parameters:
uid the KABC UID you want to the file transfer capability for
Returns:
whether the specified contact can receive files
See also:
fileTransferContacts()

KABC::Addressee::uid()

Definition at line 459 of file kimproxy.cpp.

bool KIMProxy::canRespond ( const QString &  uid  ) 

Indicate if a given contact will be able to respond.

Some media are unidirectional (e.g., sending SMS via a web interface). This refers to the contact's ability to respond as defined by the medium, not by their presence.

Someone may appear offline (SMS has no presence) to you but in fact be able to respond.

If the given KABC UID is known to more than one IM-application the result of the application which has the best presence for the contact is taken. For example if a contact is Online on ICQ and Away on AIM, the value returned by the application providing ICQ is taken.

Parameters:
uid the KABC UID you are interested in
Returns:
whether the specified contact can respond
See also:
isPresent()

KABC::Addressee::uid()

Definition at line 469 of file kimproxy.cpp.

Implements KIMProxyIface.

Definition at line 328 of file kimproxy.cpp.

QString KIMProxy::context ( const QString &  uid  ) 

Obtain the given contact's current context (home, work, or any).

Not all IM services/protocols support the concept of contexts. If the given UID maps to such a service, QString::null will be returned

If the given KABC UID is known to more than one IM-application the result of the application which has the best presence for the contact is taken. For example if a contact is Online on ICQ and Away on AIM, the value returned by the application providing ICQ is taken.

Parameters:
uid the KABC UID you want the context for
Returns:
a string describing the context, or QString::null if not supported or if the contact is unknown
See also:
isPresent()

KABC::Addressee::uid()

Definition at line 479 of file kimproxy.cpp.

QString KIMProxy::displayName ( const QString &  uid  ) 

Obtain the proxy's idea of the contact's display name.

If the given KABC UID is known to more than one IM-application the result of the application which has the best presence for the contact is taken. For example if a contact is Online on ICQ and Away on AIM, the value returned by the application providing ICQ is taken.

Useful if KABC lookups may be too slow.

Parameters:
uid the KABC UID you are interested in
Returns:
the corresponding display name or QString:null if the UID is unknown

Returned IM-contacts might not be capable of receiving file tranfers due to limitations of their clients or because they are behind a firewall. KIMProxy doesn't have the possibilities to discover this and will list them as well.

Returns a list of KABC UIDs gathered by merging the lists of each application the proxy can communicate with.

Returns:
a list of KABC UIDs capable of file transfer

bool KIMProxy::imAppsAvailable (  ) 

Checks if there are any compatible instant messaging applications available.

Available means that they are started and registered with DCOP and implementing the correct DCOP service. This information will be updated on the first call to initialize() and whenever an application registers or unregisters with DCOP, i.e. the information will be kept up to date.

Returns:
true if there are any apps available

Definition at line 553 of file kimproxy.cpp.

bool KIMProxy::initialize (  ) 

Get the proxy ready to connect.

Discover any running IM clients and setup communication handlers for them. The list of available clients is updated automatically through notification about added or removed DCOP applications as provided by DCOPClient.

It is safe to call this method more than once, initialization only occurs at the first time.

Returns:
whether the proxy is ready to use. false if there are no suitable apps running

Definition at line 215 of file kimproxy.cpp.

KIMProxy * KIMProxy::instance ( DCOPClient *  client  )  [static]

Obtain an instance of KIMProxy.

Creates a new instance if it is called for the first time. Call initialize() to check if there are applications available for communication.

Note:
KIMProxy uses DCOPClient::setNotifications() to make sure it updates its information about IM applications it interacts with, e.g. that it gets notified about newly available applications or about applications exiting
Parameters:
client your application's DCOP client
Returns:
the singleton instance of this class

Definition at line 166 of file kimproxy.cpp.

bool KIMProxy::isPresent ( const QString &  uid  )

A contact is known to the proxy if it is know to at least one IM-application the proxy is communicating with.

The method uses cached information to make it fast and not require actually communicating with the applications every time it is called.

Parameters:
uid the KABC UID you are interested in
Returns:
whether any IM-program knows of this KABC UID
