UILIBINTRO(3) Library Functions Manual UILIBINTRO(3) NAME UILib intro -- User interface library intro DESCRIPTION User interface libraries are responding to one-chracter or one-key input, return various kinds of information. They include the unfixed character string, fixed character string, marked segment position, status display character string, and candidate list character string. The application program displays the data according to the returned infor- mation. It can also control mode transition by triggering through some- thing other than key pressing (for example, selection through the mouse). The user interface library provides jrKanjiString and jrKanjiControl for the input through the TTY. It also provides XLookupKanjiString and XKanji- Control for the input through the X window. Use of the user interface library requires the following: - Through the TTY: Function jrKanjiString, jrKanjiControl Header file canna/jrkanji.h Library libcanna.a, libcanna.so - Through the X window: Function XLookupKanjiString, XKanjiControl Header file canna/kanji.h Library libXn.a, libXn.so, libcanna.a, libcanna.so Outline jrKanjiString Converts ordinary keyboard input (input through the TTY, input with X) into Kanji strings. jrKanjiControl Executes the control with jrKanjiString according to the specified parameters. XLookupKanjiString Converts the keyboard input (key event) into Kanji strings in the X window system. XKanjiControl Executes the control with XLookupKanjiString according to the specified parameters. UILIBINTRO(3) -------------------------------------------------------------------------------- JRKANJISTRING(3) Library Functions Manual JRKANJISTRING(3) NAME jrKanjiString -- Kana-to-Kanji Conversion for ordinary keyboard input SYNOPSIS #include <canna/jrkanji.h> int jrKanjiString(context_id, ch, buffer_return, bytes_buffer, kanji_status_return) int context_id; int ch; char *buffer_return; int bytes_buffer; jrKanjiStatus *kanji_status_return; DESCRIPTION jrKanjiString converts ordinary keyboard input (input through the TTY, in- put with X) into Kanji strings. jrKanjiString is a convenient routine which returns the character strings to be displayed. To convert the key input represented in ASCII code, into the Japanese characters, jrKanjiString specifies the input key code using ch. Romaji-to-Kana or Kana-to-Kanji Conversion is executed in jrKan- jiString. For a function or cursor key, specify a special code (listed in ``FUNCTION KEYS'' below) to jrKanjiString. Do not specify the sequence caused by the key. For the context identifier specified in context_id, the value is not used as it is. Instead, a context that uses the context identifier as the key is created and used. Thus, the application program may specify any value for the context identifier to be specified for jrKanjiString. It is recom- mended that the input port's file descriptor be specified for this identi- fier. If 0 is specified for the identifier, the context prepared as the system default will be used by way of exception. It is recommended that 0 be specified unless particular consideration is given to the context. The intermediate result to be displayed is returned to the application through kanji_status_return. Responding to the input, it is necessary to display the intermediate result of Romaji-to-Kana or Kana-to-Kanji Conversion. The application must dis- play the intermediate result according to the information returned by kanji_status_return, which is a jrKanjiStatus type structure. The jrKanjiStatus structure is defined as follows: typedef struct { unsigned char *echoStr; /* Character string for local echo */ int length; /* Length of the local echo character string */ int revPos; /* Offset to the reverse display field within local echo character string */ int revLen; /* Length of the reverse display within local echo echo character string */ unsigned long info; /* Other information */ unsigned char *mode; /* Mode information */ struct { unsigned char *line; /* Candidate list character string */ int length; /* Length of candidate list character string */ int revPos; /* Offset to the reverse display field within candidate list character string */ int revLen; /* Length of reverse display field within candidate list character string */ } gline; /* Information about the candidate list*/ } jrKanjiStatus; When Kana-to-Kanji conversion is used during Japanese input, information such as the readings to be converted need to be echoed (local echo). jrKanjiString does not perform display such as local echo. Instead, it re- turns the character strings to be submitted to local echo, to the applica- tion by using the jrKanjiStatus structure. The EUC character strings to be submitted to local echo include characters already converted into Kana from Romaji and conversion candidate charac- ters. Until the conversion is fixed, they are returned by the echoStr mem- ber. At this time, the length of local echo character string is returned by the length member. Also, the starting position and length (bytes) of reverse display area are returned by the revPos and revLen member, respec- tively. The buffer for local echo character strings is reserved automati- cally by jrKanjiString. It must be used only for reading. No character string must be written into this buffer. If no character string is to be submitted to local echo, 0 will be returned by the length member. The contents to be submitted to local echo may be the same as when jrKan- jiString was previously called. (This occurs, for example, when a control code is pressed and the key is disabled.) In this case, -1 returns to the length member. Mode changes and existence of information about the candidate list are passed by the info member. If info member's KanjiModeInfo bit is on, the character string indicating the new mode will return to mode. If the info member's KanjiGLineInfo bit is on, the gline structure has contained infor- mation such as the candidate list. The character string for candidate list display returns to the gline struc- ture's line member. The length, reverse dispaly starting position, and re- verse display duration of the candidate list character string return to the gline structure's line, revPos, and revLen, respectively. If there is an EUC character string fixed during conversion, it will be stored into buffer buffer_return. In this case, the length (bytes) of this character string will return. If there is no fixed character string, the return value will be 0. Using bytes_buffer, specify the size of the buffer that is to contain the fixed character string (buffer_return). If the fixed character string is longer than bytes_buffer, only the bytes_buffer substring is stored into buffer_return. In this case, the value specified in bytes_buffer will be the return value of jrKanjiString. FUNCTION KEYS For any function key that issue an Escape sequence, specify one of the fol- lowing codes as ch instead of the Escape sequence: Logical nameCode Nfer CANNA_KEY_Nfer Xfer CANNA_KEY_Xfer Up CANNA_KEY_Up Left CANNA_KEY_Left Right CANNA_KEY_Right Down CANNA_KEY_Down Insert CANNA_KEY_Insert Rollup CANNA_KEY_Rollup Rolldown CANNA_KEY_Rolldown Home CANNA_KEY_Home Help CANNA_KEY_Help S-Nfer CANNA_KEY_Shift_Nfer S-Xfer CANNA_KEY_Shift_Xfer S-Up CANNA_KEY_Shift_Up S-Left CANNA_KEY_Shift_Left S-Right CANNA_KEY_Shift_Right S-Down CANNA_KEY_Shift_Down C-Nfer CANNA_KEY_Control_Nfer C-Xfer CANNA_KEY_Control_Xfer C-Up CANNA_KEY_Control_Up C-Left CANNA_KEY_Control_Left C-Right CANNA_KEY_Control_Right C-Down CANNA_KEY_Control_Down F1 CANNA_KEY_F1 PF1 CANNA_KEY_PF1 SEE ALSO jrKanjiControl(3) RETURN VALUE If an error occurs during input processing, -1 will return as the return value of this function. In this case, the error message will be stored in external variable (char*)jrKanjiError. If a call to this function causes a character string to be fixed, the length (bytes) of this character string will return. Otherwise, 0 will re- turn. JRKANJISTRING(3) -------------------------------------------------------------------------------- JRKANJICONTROL(3) Library Functions Manual JRKANJICONTROL(3) NAME jrKanjiControl -- Control the jrKanjiControl modes and processes SYNOPSIS #include <canna/jrkanji.h> int jrKanjiControl(context_id, request, arg) int context_id; int request; char *arg; DESCRIPTION jrKanjiControl executes process request for conversion context context_id. Some processes are accompanied by the argument, specified in arg. jrKanjiControl controls the following 13 functions: request name Function KC_INITIALIZE Initializes Kana-to-Kanji conversion. KC_CHANGEMODE Changes the input mode. KC_SETWIDTH Specifies the width used to display the candidate KC_FINALIZE Finalizes (terminates) Kana-to-Kanji conversion process- ing. KC_SETUNDEFKEYFUNCTION Sets a function for an undefined key. KC_SETMODEINFOSTYLE Specifies whether mode information is represented in nu- meric form. KC_KAKUTEI Fixes the currently entered character string. KC_KILL Deletes the currently entered character string. KC_QUERYMODE Queries about the current mode. KC_SETSERVERNAME Specifies the server to be connected. KC_SETINITFILENAMESpecifies the customize file. KC_CLOSEUICONTEXT Closes the context. KC_QUERYMAXMODESTRObtains the maximum length of mode display character string. Basically, jrKanjiControl is enabled only for something specified in the context. This rule does not apply to the initialize and terminate processes. The unfixed character string condition may change, or details of the mode may vary, depending on the jrKanjiControl operation. If this may occur, pass the pointer to a structure that can contain the varied information in the arg field. This structure is defined as follows: typedef struct { int val; /* The length of the character string in the buffer returns. */ unsigned char *buffer; /* Specifies the buffer used to store the fixed character string. */ int bytes_buffer; /* Specifies the size of the above buffer. */ jrKanjiStatus *ks; /* Pointer to the structure that contains information about the unfixed character string. */ } jrKanjiStatusWithValue; The jrKanjiControl functions can be executed in the following ways: (1) KC_INITIALIZE -- Initializes Kana-to-Kanji conversion. KC_INITIALIZE initializes Kana-to-Kanji conversion by specifying KC_INITIALIZE in the request field. Specify one of the following in arg: (1) the pointer to the char ** type variable used to store the warning message and (2) NULL. The initialize process is basically executed automatically when jrKanjiString(3) is first called. This is skipped by using jrKanji- Control for initialization. For example, when control about Kana-to-Kanji conversion is executed using jrKanjiControl before use of jrKanjiString(3), Kana-to-Kanji conversion must be initialized. When the process terminates normally, 0 returns as the jrKanjiControl return value. When it terminates abnormally, -1 returns. When KC_INITIALIZE is executed, a warning, rather than an error, may occur. When it occurs, the pointer to the warning character string array is stored in and returns to the variable specified in arg. If no warning occurs, NULL is stored and returns. (Example) int res; /* Prepare for error return */ char **warning; ..... res = jrKanjiControl(0, KC_INITIALIZE, &warning); if (warning) { char **p; for (p = warning ; *p ; p++) { fprintf(stderr, "%s0, *p); } } In the library, malloc is done for the warning message returning to the third argument. This message is freed when KC_INITIALIZE or KC_FINALIZE is executed next. The application programmer must not free it. The maximum number of warning messages is restricted to 64 now. The subsequent ones are discarded. The following warnings may be included in a message: - All customize files including those of the system are unavailable. - The customize file contains a syntax error. - The Romaji-to-Kana conversion dictionary is unavailable. - The Kana-to-Kanji conversion dictionary is unavailable. - Connection to the Kana-to-Kanji conversion server is disabled. If NULL is specified as the third argument, any warning message will be discarded. (2) KC_CHANGEMODE -- Changes the input mode. KC_CHANGEMODE changes the input mode from the application. Specify KC_CHANGEMODE in the request field. Specify the jrKanjiStatusWith- Value structure in arg. The Japanese mode is changed by specifying the mode number with the val member of jrKanjiStatusWithValue structure. The mode number is indicated by the following macros: Macro number Mode CANNA_MODE_AlphaMode Alphabet mode CANNA_MODE_HenkanMode Conversion input mode CANNA_MODE_KigoMode Symbol input mode CANNA_MODE_ZenHiraKakuteiMode Full-wide Hiragana fixed input mode CANNA_MODE_ZenKataKakuteiMode Full-wide Katakana fixed mode CANNA_MODE_HanKataKakuteiMode Half-wide Katakana fixed input mode CANNA_MODE_ZenAlphaKakuteiMode Full-wide alphabet fixed input mode CANNA_MODE_HanAlphaKakuteiMode Half-wide alphabet fixed input mode CANNA_MODE_HexMode Hexadecimal code input mode CANNA_MODE_BushuMode Bushu input mode CANNA_MODE_TorokuMode Word register mode This function causes much dispaly (mode name etc.) to vary in re- sponse to a mode change. The display change is returned by the jrKanjiStatusWithValue structure specified as arg. (Example) jrKanjiStatus ks; jrKanjiStatusWithValue ksv; unsigned char buf[SOMESIZE]; ..... ksv.ks = &ks; ksv.buffer = buf; ksv.bytes_buffer = SOMESIZE; ksv.val = CANNA_MODE_HexMode; jrKanjiControl(context, KC_CHANGEMODE, &ksv); len = ksv.val; ..... /* Information about the unfixed or fixed character string is returned by ksv. */ (3) KC_SETWIDTH -- Specifies the width used to display the candidate list. KC_SETWIDTH specifies the number of columns of the area on which the candidate list is to be displayed. The width of one column equals that of an alphabetical or half-wide Katakana character. Each full- wide Kanji character occupies two columns. Using KC_SETWIDTH, spec- ify the width of candidate list display area to be specified in the request field. At this time, specify the number of columns in arg. (Example) jrKanjiControl(0, KC_SETWIDTH, (char *)60); (4) KC_FINALIZE -- Finalizes (terminates) processing of Kana-to-Kanji conversion KC_FINALIZE specifies that Kana-to-Kanji conversion also finalizes (terminates) at the end of the program and in other cases. Be sure to execute this process when terminating Kana-to-Kanji con- version processing. All contents learned up to now are registered in the file. Specify KC_FINALIZE in the request field. When the process terminates normally, 0 returns. When it terminates abnormally, -1 returns. When KC_FINALIZE is executed, a warning, rather than an error, may occur. When it occurs, the pointer to the warning character string array is stored in and returns to the variable specified in arg. If no warning occurs, NULL is stored and returns. (Example) int res; /* Prepare for error return */ char **warning; ..... res = jrKanjiControl(0, KC_FINALIZE, &warning); if (warning) { char **p; for (p = warning ; *p ; p++) { fprintf(stderr, "%s0, *p); } } In the library, malloc is done for the warning message returning to the third argument. This message is freed when KC_INITIALIZE or KC_FINALIZE is executed next. The application programmer must not free it. The maximum number of warning messages is restricted to 64 now. The subsequent ones are discarded. The following warning may be included in a message: - The dictionary cannot be unmounted. If NULL is specified as the third argument, any warning message will be discarded. (5) KC_SETUNDEFKEYFUNCTION -- Sets a function for an undefined key. For example, if you press CTRL-t during input of a reading, it is re- garded as undefined key input. The following processes are executed, responding to undefined key input: Macro name Process kc_normal Beep kc_through Passes the input to the application kc_kakutei Fixes the input and passes it to the application program. kc_kill Deletes the input and passes it to the application pro- gram. If kc_normal is specified, the function set in external variable jr- BeepFunc is called automatically by the library when an undefined key is input. If the value is not set in jrBeepFunc, nothing occurs when ``jrBeepFunc == NULL'' appears. (Example) extern (*jrBeepFunc)(), beep(); jrBeepFunc = beep; jrKanjiControl(0, KC_SETUNDEFKEYFUNCTION, kc_normal); (6) KC_SETMODEINFOSTYLE -- Specifies mode information representation. You may want to display mode information with data such as the bit map, rather than character strings. In this case, return of numeric data as mode information helps you execute the process. Specify KC_SETMODEINFOSTYLE in jrKanjiControl, and pass 1 to arg. After this, one character representing the mode code (numeric) plus To con- vert the value into the mode code, subtract '@' (0x40) from the re- turned character string. For the mode codes, see the mode change de- scription of Item (2) KC_CHANGEMODE. (7) KC_KAKUTEI, (8) KC_KILL -- Kill the currently input character string. You may want to relinquish the currently entered character string for some reason. There are two relinquishing methods. One is to relin- quish the character string after including the currently entered character string as a fixed one. The other is to discard the charac- ter string completely then relinquish it. For the first method, specify KC_KAKUTEI in jrKanjiControl. For the second method, specify KC_KILL. Each of the above influences the display. The jrKanjiStatusWithValue must thus be specified as the third argument. (Example) jrKanjiStatusWithValue ksv; jrKanjiStatus ks; unsigned char buf[SOMESIZE]; ..... ksv.ks = &ks; ksv.buffer = buf; ksv.bytes_buffer = SOMESIZE; jrKanjiControl(context, KC_KAKUTEI, &ksv); len = ksv.val; ..... (9) KC_QUERYMODE -- Inquiry about the mode To inquire about the current mode, specify KC_QUERYMODE in jrKanji- Control. Specify the pointer to the character array in which the mode charac- ter string is to be stored. The mode character string is a character string ending with a null character. To return a numeric here, spec- ify KC_SETMODEINFOSTYLE in jrKanjiControl to change the mode charac- ter string style. (Example) char currentMode[MAXMODELEN]; ..... jrKanjiControl(0, KC_QUERYMODE, currentMode); ..... (10) KC_SETSERVERNAME Specifies the server to be connected. KC_SETSERVERNAME enables you to switch the Kana-to-Kanji conversion server without terminating the application program. To set the server to connect as the Kana-to-Kanji conversion server, specify KC_SETSERVERNAME in jrKanjiControl. In the third argument, specify the name of the server to be connected. (11) KC_SETINITFILENAME -- Specifies the customize file. KC_SETINITFILENAM enables the application program to change the cus- tomize file. To change the customize file, specify KC_SETINITFILE- NAME as the second argument and the file name character string as the third argument. This process must be executed before KC_INTIALIZE. (Example) char *inifile = "app-own.canna" ..... jrKanjiControl(0, KC_SETINITFILENAME, initfile); ..... (12) KC_CLOSEUICONTEXT Closes the context. Any integer may be assigned as the context ID that represents the conversion context. A context ID that has never been used can be as- signed to jrKanjiString or jrKanjiControl. In this case, initializa- tion for this context is executed to reserve the required memory. If an input port used up to now is not used, you may want to free the memory reserved for the context ID assigned to this port. To do so, call jrKanjiControl by specifying KC_CLOSEUICONTEXT as the second ar- gument. Because this process causes a display change, specify jrKanjiSta- tusWithValue as the third structure. (Example) jrKanjiStatusWithValue ksv; jrKanjiStatus ks; unsigned char buf[SOMESIZE]; ..... ksv.ks = &ks; ksv.buffer = buf; ksv.bytes_buffer = SOMESIZE; jrKanjiControl(0, KC_CLOSEUICONTEXT, &ksv); ..... (13) KC_QUERYMAXMODESTR -- Obtains the maximum length of mode display character string. The mode display character string can be customized using the ini- tialize file. It is necessary to examine the size of the display area (in the customized resulting mode display character string) that is to be reserved. Specify KC_QUERYMAXMODESTR as the second argu- ment, then call jrKanjiControl. As a result, the number of columns necessary for the mode display character string is returned. The number of columns is represented, defining that the width of one half-wide alphanumeric character is 1. The third argument is unused; dummy value 0 is assigned to it. (Example) int max_mode_columns; ..... max_mode_columns = jrKanjiControl(0, KC_QUERYMAXMODESTR, 0); ..... JRKANJICONTROL(3) -------------------------------------------------------------------------------- XLookupKanjiString(3) Library Functions Manual XLookupKanjiString(3) NAME XLookupKanjiString -- Converts the keyboard input into Kanji SYNOPSIS #include <X11/Xlib.h> #include <X11/kanji.h> int XLookupKanjiString(event_struct, buffer_return, bytes_buffer, keysym_return, status_return, kanji_status_return) XKeyEvent *event_struct; char *buffer_return; int bytes_buffer; KeySym *keysym_return; XComposeStatus *status_return; XKanjiStatus *kanji_status_return; ARGUMENTS event_struct Specifies the key event. buffer_return Returns the resulting Kanji string. bytes_buffer Specifies the buffer length. keysym_return Returns the key symbol. NULL may be specified status_return Specifies the pointer to the XCompose structure. kanji_status_return Returns the Kana-to-Kanji conversion status. DESCRIPTION XLookupKanjiString is a convenient routine that associates a key event with a Japanese character string. It uses the modifier key bit to processes such as shift, lock, and control. XLookupKanjiString enables eight- and 16-bit Japanese characters to be processed. XLookupKanjiString processes alphabetical characters in the same way as XLookupString. For Japanese character processing, Romaji-to-Kana conversion and Kana-to- Kanji conversion are done in this function. The XKanjiStatus, defined be- low, is used during Japanese data input: typedef struct _XKanjiStatus { unsigned char *echoStr; /* local echo string */ int length; /* length of echo string */ int revPos; /* reverse position */ int revLen; /* reverse length */ unsigned long info; /* other informations */ unsigned char *mode; /* mode information */ struct { unsigned char *line; /* a grance of Kanji characters */ int length; /* length of it */ int revPos; /* reverse position of it */ int revLen; /* reverse length of it */ } gline; /* a grancing line information */ } XKanjiStatus; #define KanjiModeInfo 01 #define KanjiGLineInfo 02 When Kana-to-Kanji conversion is used during Japanese input, information such as the readings to be converted need to be echoed (local echo). XLookupKanjiString does not perform display such as local echo. Instead, it returns the character strings to be submitted to local echo, to the ap- plication by using the XKanjiStatus structure. The EUC character strings to be submitted to local echo include characters already converted into Kana from Romaji and conversion candidate charac- ters. Until the conversion is fixed, they are returned by the echoStr mem- ber. At this time, the length of local echo character string is returned by the length member. Also, the starting position and length (bytes) of reverse display are returned by the revPos and revLen member, respectively. The buffer for local echo character strings is reserved automatically by XLookupKanjiString. It should be used only for reading. No character string must be written into this buffer. If no character string is to be submitted to local echo, 0 will return to the length member. The contents to be submitted to local echo may be the same as when XLookup- KanjiString was previously called. (This occurs, for example, when the Shift key is pressed.) In this case, -1 returns to the length member. Mode changes and existence of information about the candidate list are passed by the info member. If info member's KanjiModeInfo bit is on, the character string indicating the new mode will return to mode. If the info member's KanjiGLineInfo bit is on, the gline structure has contained infor- mation such as the candidate list. The character string for candidate list display returns to the gline struc- ture's line member. The length, reverse dispaly starting position, and re- verse display duration of the candidate list character string return to the gline structure's line, revPos, and revLen, respectively. If there is an EUC character string fixed during conversion, it will be stored in buffer_return. In this case, the length (bytes) of this charac- ter string will return as the return value of this function. If there is no fixed character string, the return value will be 0. XLookupKanjiString(3) -------------------------------------------------------------------------------- XKANJICONTROL(3) Library Functions Manual XKANJICONTROL(3) NAME XKanjiControl -- Control the XLookupKanjiString mode and process. SYNOPSIS #include <X11/kanji.h> int XKanjiControl(dpy, win, request, arg) Display dpy; Window win; int request; char *arg; DESCRIPTION XKanjiControl executes a process that relates to Japanese input within the window defined by dpy and win. The process is specified in request. Some processes are accompanied by the argument, specified in arg.

KC_INITIALIZE initializes Kana-to-Kanji conversion by specifying KC_INITIALIZE in the request field. Specify one of the following in arg: (1) the pointer to the char ** type variable used to store the warning message and (2) NULL.

This message is freed when KC_INITIALIZE or KC_FINALIZE is executed next. The application programmer must not free it. The maximum number of warning messages is restricted to 64 now. The subsequent ones are discarded. The following warnings may be included in a message: - All customize files including those of the system are unavailable. - The customize file contains a syntax error. - The Romaji-to-Kana conversion dictionary is unavailable. - The Kana-to-Kanji conversion dictionary is unavailable. - Connection to the Kana-to-Kanji conversion server is disabled. If NULL is specified as the fourth argument, any warning message will be discarded. (2) KC_CHANGEMODE -- Changes the input mode. KC_CHANGEMODE changes the input mode from the application. Specify KC_CHANGEMODE in the request field. Specify the XKanjiStatusWith- Value structure in arg. The Japanese mode is changed by specifying the mode number with the val member of XKanjiStatusWithValue struc- ture. The mode number is indicated by the following macros: Macro number Mode CANNA_MODE_AlphaMode Alphabet mode CANNA_MODE_HenkanMode Conversion input mode CANNA_MODE_KigoMode Symbol input mode CANNA_MODE_ZenHiraKakuteiMode Full-wide Hiragana fixed input mode CANNA_MODE_ZenKataKakuteiMode Full-wide Katakana fixed mode CANNA_MODE_HanKataKakuteiMode Half-wide Katakana fixed input mode CANNA_MODE_ZenAlphaKakuteiMode Full-wide alphabet fixed input mode CANNA_MODE_HanAlphaKakuteiMode Half-wide alphabet fixed input mode CANNA_MODE_HexMode Hexadecimal code input mode CANNA_MODE_BushuMode Bushu input mode CANNA_MODE_TorokuMode Word register mode This function causes much dispaly (mode name etc.) to vary in re- sponse to a mode change.

KC_SETWIDTH specifies the number of columns of the area on which the candidate list is to be displayed. The width of one column equals that of an alphabetical or half-wide Katakana character. Each full- wide Kanji character occupies two columns. Using KC_SETWIDTH, spec- ify the width of candidate list display area to be specified in the request field.

This message is freed when KC_INITIALIZE or KC_FINALIZE is executed next. The application programmer must not free it. The maximum number of warning messages is restricted to 64 now. The subsequent ones are discarded. The following warning may be included in a message: - The dictionary cannot be unmounted. If NULL is specified as the fourth argument, any warning message will be discarded. (5) KC_SETUNDEFKEYFUNCTION -- Sets a function for an undefined key. For example, if you press CTRL-t during input of a reading, it is re- garded as undefined key input. The following processes are executed, responding to undefined key input: Macro name Process kc_normal Beep kc_through Passes the input to the application program. kc_kakutei Fixes the input and passes it to the application program. kc_kill Deletes the input and passes it to the application pro- gram. If kc_normal is specified, the function set in external variable jr- BeepFunc is called automatically by the library when an undefined key is input. If the value is not set in jrBeepFunc, nothing occurs when "jrBeepFunc == NULL" appears. (Example) extern (*jrBeepFunc)(), beep(); jrBeepFunc = beep; XKanjiControl(dpy, win, KC_SETUNDEFKEYFUNCTION, kc_normal); (6) KC_SETMODEINFOSTYLE -- Specifies mode information representation. You may want to display mode information with data such as the bit map, rather than character strings. In this case, return of numeric data as mode information helps you execute the process. Specify KC_SETMODEINFOSTYLE in XKanjiControl, and pass 1 to arg. After this, one character representing the mode code (numeric) plus To convert the value into the mode code, subtract '@' (0x40) from the returned character string. For the mode codes, see the mode change descrip- tion of Item (2) KC_CHANGEMODE. (7) KC_KAKUTEI, (8) KC_KILL -- Kill the currently input character string. You may want to relinquish the currently entered character string for some reason. There are two relinquishing methods. One is to relin- quish the character string after including the currently entered character string as a fixed one. The other is to discard the charac- ter string completely then relinquish it. For the first method, specify KC_KAKUTEI in jrKanjiControl. For the second method, specify KC_KILL. Each of the above influences the display. The XKanjiStatusWithValue must thus be specified as the fourth argument. (Example) XKanjiStatusWithValue ksv; XKanjiStatus ks; unsigned char buf[SOMESIZE]; ..... ksv.ks = &ks; ksv.buffer = buf; ksv.bytes_buffer = SOMESIZE; XKanjiControl(dpy, win, KC_KAKUTEI, &ksv); len = ksv.val; ..... (9) KC_QUERYMODE -- Inquiry about the mode To inquire about the current mode, specify KC_QUERYMODE in XKanjiCon- trol. Specify the pointer to the character array in which the mode charac- ter string is to be stored. The mode character string is a character string ending with a null character. To return a numeric here, spec- ify KC_SETMODEINFOSTYLE in XKanjiControl to change the mode character string style. (Example) char currentMode[MAXMODELEN]; ..... XKanjiControl(dpy, win, KC_QUERYMODE, currentMode); ..... (10) KC_SETSERVERNAME -- Specifies the server to be connected. KC_SETSERVERNAME enables you to switch the Kana-to-Kanji conversion server without terminating the application program. To set the server to connect as the Kana-to-Kanji conversion server, specify KC_SETSERVERNAME in XKanjiControl. In the fourth argument, specify the name of the server to be connected. (11) KC_SETINITFILENAME -- Specifies the customize file. KC_SETINITFILENAM enables the application program to change the cus- tomize file. To change the customize file, specify KC_SETINITFILE- NAME as the third argument and the file name character string as the fourth argument. This process must be executed before KC_INTIALIZE. (Example) char *inifile = "app-own.canna" ..... XKanjiControl(dpy, win, KC_SETINITFILENAME, initfile); ..... (12) KC_CLOSEUICONTEXT Closes the context. When XKanjiControl or XLookupKanjiString is called, one conversion context is assigned to combination of dpy and win. Combination of dpy and win not used yet can be specified for XKanjiControl or XLookupKanjiString. When this is done, a new context is created for the window and the required memory is reserved. If a window used up to now is not used, you may want to free the con- text memory that has been assigned to this window. To do so, call XKanjiControl by specifying KC_CLOSEUICONTEXT as the third argument. Because this process causes a display change, specify XKanjiSta- tusWithValue as the fourth structure. (Example) XKanjiStatusWithValue ksv; XKanjiStatus ks; unsigned char buf[SOMESIZE]; ..... ksv.ks = &ks; ksv.buffer = buf; ksv.bytes_buffer = SOMESIZE; XKanjiControl(dpy, win, KC_CLOSEUICONTEXT, &ksv); ..... (13) KC_QUERYMAXMODESTR -- Obtains the maximum length of mode display character string. The mode display character string can be customized using the ini- tialize file. It is necessary to examine the size of the display area (in the customized resulting mode display character string) that is to be reserved. Specify KC_QUERYMAXMODESTR as the third argument, then call XKanjiControl. As a result, the number of columns neces- sary for the mode display character string is returned. (The number of columns is represented, defining that the width of one half-wide alphanumeric character is 1. The fourth argument is unused; dummy value 0 is assigned to it. (Example) int max_mode_columns; ..... max_mode_columns = XKanjiControl(dpy, win, KC_QUERYMAXMODESTR, 0); ..... XKANJICONTROL(3)
