Detailed Description

Generic DCOP interface for KDE instant messenger applications.

The interface has two parts:

• methods to get information about IM-contacts, such as their reachability or their presence status (if the are online or away, etc)
• methods to initiate communication with IM-contacts, e.g. sending messages

Note

If you are looking for a information about accessing application's that implement this interface, have a look at the KIMProxy class.

Contacts are identified using unique identifier strings (UID) used by KABC, the KDE address book library. The UID generation is handled by TDEABC::Addressee so the your application will either have to access the address book or provide a possibility for associating a contact of your application with an entry of the address book.

Note

one omission of this interface is the lack of control over the range of values used for protocols' names.

If you are implementing this interface, note that your application must have the following information in its desktop file, so that it can be identified as providing KIMIface at runtime:

X-DCOP-ServiceName=<application-name>
ServiceTypes=DCOP/InstantMessenger

and the class implementing KIMIface must pass "KIMIface" to the DCOPObject constructor:

// just need TQObject inheritance and TQ_OBJECT if you want signals and slots
// no need to use K_DCOP macro again
 
class MyIMIface : public TQObject, public KIMIface
{
    TQ_OBJECT
public:
   MyIMIface(TQObject* parent = 0, const char* name) :
       DCOPObject("KIMIface"), // <-- passing the interface name as required
       TQObject(parent, name) {}
};

The DCOP part of the interface needs to be processed by the DCOP IDL compiler. The KDE autotools framework will do this automatically, all you have to do is add kimiface.skel and kimiface.stub to the SOURCES list in your Makefile.am

Member Function Documentation

addContact

virtual bool KIMIface::addContact ( const TQString &  contactId, const TQString &  protocol  )

pure virtual

Add a new contact given its protocol specific identifier.

Implementations might add the contact silently, including sending an authorization request if necessary, ask the user for confirmation or just prefill the usual contact addingGUI.

Parameters

contactId	the protocol specific identifier for the contact e.g. UIN for ICQ, screenname for AIM, nick for IRC
protocol	the IM protocol/service to use. See protocols()

Returns

whether the add succeeded. false may signal already present, protocol not supported, or add operation not supported.

allContacts

virtual TQStringList KIMIface::allContacts ( )

pure virtual

Obtain a list of IM-contacts that are known to the application.

Return a list of KABC UIDs of all the contacts you have such IDs for.

Returns

a list of KABC UIDs known to the application

isPresent()

TDEABC::Addressee::uid()

canReceiveFiles

virtual bool KIMIface::canReceiveFiles ( const TQString &  uid )

pure virtual

Indicate if a given contact can receive files.

Parameters

uid	the KABC UID you want to the file transfer capability for

Returns

whether the specified contact can receive files

See also

fileTransferContacts()

TDEABC::Addressee::uid()

canRespond

virtual bool KIMIface::canRespond ( const TQString &  uid )

pure virtual

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.

Parameters

uid	the KABC UID you are interested in

Returns

whether the specified contact can respond

See also

isPresent()

TDEABC::Addressee::uid()

chatWithContact

virtual void KIMIface::chatWithContact ( const TQString &  uid )

pure virtual

Start a chat session with the specified contact.

Applications that do not support a chat mode or when the IM-service of the given contact does not support it, this can also open a normal message input GUI.

Parameters

uid	the KABC UID you want to chat with

TDEABC::Addressee::uid()

context

virtual TQString KIMIface::context ( const TQString &  uid )

pure virtual

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, just return TQString::null

Parameters

uid	the KABC UID you want the context for

Returns

a string describing the context, or TQString::null if not supported or if the contact is unknown

See also

isPresent()

TDEABC::Addressee::uid()

displayName

virtual TQString KIMIface::displayName ( const TQString &  uid )

pure virtual

Obtain the IM app's idea of the contact's display name.

Useful if KABC lookups may be too slow. Should return whatever the application uses in its contact list or similar GUI, e.g. a nick name, a user configured name string, etc.

Parameters

uid	the KABC UID you are interested in

Returns

the corresponding display name or TQString:null if the UID is unknown

TDEABC::Addressee::uid()

fileTransferContacts

virtual TQStringList KIMIface::fileTransferContacts ( )

pure virtual

Obtain a list of IM-contacts who may receive file transfers.

Return a list of KABC UIDs of the contacts that are capable of receiving file transfers based on the IM-service they are associated with, i.e. if it is technically able to provide this, on their online state, i.e. can likely not receive files while offline, and perhaps even information your application has additionally, e.g. a user config that tells you that the contact is behind a firewall.

The simplest implementation is to return the same list as onlineContacts(), provided all the IM-services that are currently used support it.

Returns

a list of KABC UIDs capable of file transfer

Return the image the application would use to display a contact's presence. The size and other properties of the image are currently unspecified.

Parameters

uid	the KABC UID you want the presence icon for

Returns

a pixmap representing the contact's presence or a null pixmap if the contact is unknown. See TQPixmap::isNull()

Check if you can map the given KABC UID to one if the IM-contacts, e.g. the would be part of the list returned by allContacts()

Parameters

uid	the KABC UID you are interested in

Returns

whether the program knows of this KABC UID

Parameters

contactId	the protocol specific identifier for the contact, e.g. UIN for ICQ, screenname for AIM, nick for IRC
protocol	the IM protocol/service to check. See protocols()

Returns

the KABC UID for the given contact or TQString::null if not found or either input stream was empty or the protocol is not supported

messageContact

virtual void KIMIface::messageContact ( const TQString &  uid, const TQString &  message  )

pure virtual

Send a single message to the specified contact.

Any response will be handled by the IM client as a normal conversation.

Implementations might send the message silently, ask the user for permission or just prefill the usual message input GUI.

Note

As sending any text could potentially be a breach of the user's privacy it is recommended to let the user know about it.

This could be used to send a message without having to know the KABC UID of the contact or without having to add it first.

Parameters
