It is built for IRC, which I also develop and is naturally biased towards IRC, but it should work very well with other protocols too. I will try to explain as careful as possible in this document how to use chat.dll -- General guidelines -- There is ONE rule a protocol MUST follow to use this: 1. Do NOT touch hContacts that has a byte "ChatRoom" set to ANYTHING other than 0! (Could be 1, 2, 3, ...) This is because chat.dll adds contacts to the clist using the protocol name supplied by the protocol. But this will naturally not work well if the protocol also tampers with the contacts. The value of the BYTE indicates which type of window/contact it is (see the GCW_* flags below). There is two exceptions to this rule: * You should continue to handle the right click menu items of these contacts as usual, by hooking the menu prebuild hook etc. Chat.dll can not handle this in an efficient manner! * You should also handle when the user deletes the contact/room from the contact list, as the protocol will then most likely have to send some message to the server that the user has left the room. NOTE. Chat keeps its own copies of strings passed. * * Example of implementing this rule * *: * * This is a code snippet that is common in protocols * *: hContact = (HANDLE) CallService(MS_DB_CONTACT_FINDFIRST, 0, 0); while (hContact) { szProto = (AnsiChar * ) CallService(MS_PROTO_GETCONTACTBASEPROTO, (WPARAM) hContact, 0); if (szProto != NULL && !lstrcmpi(szProto, PROTONAME)) { ... do something with the hContact here; } hContact = (HANDLE) CallService(MS_DB_CONTACT_FINDNEXT, (WPARAM) hContact, 0); } * * You should do this instead * *: hContact = (HANDLE) CallService(MS_DB_CONTACT_FINDFIRST, 0, 0); while (hContact) { szProto = (AnsiChar * ) CallService(MS_PROTO_GETCONTACTBASEPROTO, (WPARAM) hContact, 0); if (szProto != NULL && !lstrcmpi(szProto, PROTONAME)) { if (DBGetContactSettingByte(hContact, PROTONAME, "ChatRoom", 0) == 0) { ... do something with the hContact here; } } hContact = (HANDLE) CallService(MS_DB_CONTACT_FINDNEXT, (WPARAM) hContact, 0); } There is not more to it than that! To recapitulate: do NOT touch contacts where the BYTE "ChatRoom" is set to anything other than 0, *) { OK, enough of the precautions, HOW DO YOU USE CHAT? In short you need to do FOUR things: 1. REGISTER your protocol with Chat Only registered protocols can use Chat 2. CREATE SESSIONS when your protocol are joining a group chat room. (One per room joined) These sessions will be put on the contact-list and are managed totally by chat. This is the reason you must obey to the "precautions" I mentioned above. Do not tamper directly with Chat's hContacts. Use Services provided by Chat instead. 3. SEND EVENTS to the sessions created in #3. These events reflect users joining/leaving/speaking etc. 4. DESTROY SESSIONS when the user leaves the room (ie the session is not needed anymore). These four points are implemented in three services: MS_GC_REGISTER, MS_GC_NEWSESSION and MS_GC_EVENT. } //------------------------- SERVICES ------------------------ { Step 1. -- REGISTER with Chat -- The first thing that a protocol need to do is register with Chat. This is best done when ALL modules has loaded (ME_SYSTEM_MODULESLOADED). The registration is needed to make sure that the protocol obey rule 1 mentioned above, but also to set protocol specific preferences. * Use MS_GC_REGISTER like this: CallService(MS_GC_REGISTER, 0, (LPARAM)(GCREGISTER *) &gcr; * returns 0 on success or error code on failure. } const // Flags GC_BOLD = $0001; //enable the 'bold' button GC_ITALICS = $0002; //enable the 'italics' button GC_UNDERLINE = $0004; //enable the 'underline' button GC_COLOR = $0008; //enable the 'foreground color' button GC_BKGCOLOR = $0010; //enable the 'background color' button GC_ACKMSG = $0020; //the protocol must acknowlege messages sent GC_TYPNOTIF = $0040; //NOT SUPPORTED YET! Enable typing notifications. GC_CHANMGR = $0080; //enable the 'channel settings' button GC_SINGLEFORMAT = $0100; //the protocol supports only 1 formatting per message GC_FONTSIZE = $0200; //enable font size selection // Error messages GC_REGISTER_WRONGVER = 1; //You appear to be using the wrong version of this API. Registration failed. GC_REGISTER_ERROR = 2; //An internal error occurred. Registration failed. GC_REGISTER_NOUNICODE = 3; //MS_GC_REGISTER returns this error if the Unicode version of chat //is not installed and GC_UNICODE is set. Registration failed // GCREGISTER struct type TGCREGISTER = record cbSize :int; //Set to sizeof(GCREGISTER); dwFlags :DWORD; //Use GC_* flags above to indicate features supported pszModule :PAnsiChar; //This MUST be the protocol name as registered with Miranda IM pszModuleDispName:TChar; //This is the protocol's real name as it will be displayed to the user iMaxText :int; //Max message length the protocol supports. Will limit the typing area input. 0 = no limit nColors :int; //Number of colors in the colorchooser menu for the color buttons. Max = 100 pColors :^TCOLORREF;//pointer to the first item in a static COLORREF array containing the colors //that should be showed in the colorchooser menu. //ie: COLORREF crCols[nColors]; // pColors = &crCols[0]; end; const MS_GC_REGISTER:PAnsiChar = 'GChat/Register'; { Step 2. -- CREATE a new SESSION -- Create a new session (chat room) and set various settings related to it. The chat room will not be shown to the user until the 'set up' phase is completed and SESSION_INITDONE is sent. See the MS_GC_EVENT for that. * Use MS_GC_NEWSESSION like this: CallService(MS_GC_NEWSESSION, 0, (LPARAM)(GCSESSION *) &gcr; * returns 0 on success or error code on failure } // Session type GCW_CHATROOM = 1; // the session is a dedicated multi user chat room. ex "IRC channels". // A hContact will be added for the session GCW_SERVER = 2; // the session is used as a network console. ex "IRC server window" // A hContact will be added for the session, but it will default to being // hidden (on the CList) GCW_PRIVMESS = 3; // NOT SUPPORTED YET! the session is a 1 to 1 session, but with additional // support for adding more users etc. ex "MSN session". // Error messages GC_NEWSESSION_WRONGVER = 1; //You appear to be using the wrong version of this API. GC_NEWSESSION_ERROR = 2; //An internal error occurred. // GCSESSION structure type TGCSESSION = record cbSize :int; //Set to sizeof(GCSESSION); iType :int; //Use one of the GCW_* flags above to set the type of session pszModule :PAnsiChar; //The name of the protocol owning the session (the same as pszModule when you register) szName :TCHAR; //The name of the session as it will be displayed to the user szID :TCHAR; //The unique identifier for the session. szStatusbarText:TCHAR; //Optional text to set in the statusbar of the chat room window, or NULL. dwFlags :dword; dwItemData :int_ptr; //Set user defined data for this session. Retrieve it by using the GC_EVENT_GETITEMDATA event end; const MS_GC_NEWSESSION:PAnsiChar = 'GChat/NewChat'; { Step 3 -- SEND an EVENT -- Events is what drives Chat! After having created the session in Step 2 it is time to make it work for real. Follow these guidelines: 1. Start off by telling Chat what possible statuses a user can have (in the nicklist) by sending GC_EVENT_ADDGROUP as many times as needed. Also supply an icon to go with this status. Ex "Voice status" on IRC 2.Then send "JOIN" events (GC_EVENT_JOIN) to populate the user list. You will need to send one event per user that should be added. As long as SESSION_INITDONE has not been sent these events will not show up in the log. 3.When you are done with filling the user list it is a good time to end the set up phase and make the window visible by calling GC_EVENT_CONTROL event with wParam = SESSION_INITDONE. 4.You will also want to send a GC_EVENT_CONTROL with wParam = SESSION_ONLINE to make the statusbar and the CList item go to "online" status You have now set up the session and made it active. A CList hContact has been added to the contact list and a chat room window is associated to the session. Send EVENTS to Chat users speaking, users joining and so on. See below for full list of what events are possible. IMPORTANT: For sending events you'll use the GCEVENT and GCDEST structures. A GCDEST structure pointer is passed inside GCEVENT and it tells Chat what event type it is and what session it is related to. The GCDEST structure and its members are ALWAYS used (but the members can be NULL in some occasions). Depending on what type of event you are sending, the members of GCEVENT have different usage. Each event and how to use the members are discussed below. The "bAddToLog" and "time" members are always valid and always mean the same. bAddToLog = TRUE means that the event is added to the disk log (at least when this makes sense). This can be used by Jabber for instance, when it needs to add channel history to the window, but without logging to disk. The "time" member is the timestamp of the event.(Tip. use the function time(NULL) to set the current time) NOTE. It is possible to send formatted text (bold, italics, underlined, foreground color and background color) to Chat by using the following identifiers in the text (pszText): %cXX - set the foreground color ( XX is the zero based decimal index of the color registered in MS_GC_REGISTER.. Always use two digits ) %C - reset foreground color to default %fXX - set the background color ( XX is the zero based decimal index of the color registered in MS_GC_REGISTER.. Always use two digits ) %F - reset the background color to default %b - enable bold %B - disable bold %u - enable underlined %U - disable underlined %i - enable italics %I - disable italics %r - reset all to default %% - escape the formatting. Translates to % IMPORTANT. If you have specified GC_COLOR or GC_BKGCOLOR when you registered you can expect to get these identifiers in the text you receive from Chat as well. Make sure % is ALWAYS translated to %% in text you send to Chat to avoid accidental formatting. NOTE. You will not get %cRRRGGGBBB back, instead you will get the index of the colour as registered with GC_REGISTER. Eg %c3 (the fourth colour of your index) * Use MS_GC_EVENT like this: CallService(MS_GC_EVENT, 0, (LPARAM)(GCEVENT *) &gce; * returns 0 on success or error code on failure } // * List of possible events to send to Chat.
