Not yet! In fact, as I dig into the problem further, I get more confused
and discouraged. Here's why.
1. If I set the input style to be "over the spot" as in lib/flresource,
..............
if (fl_context->xim) {
int style = XIMPreeditPosition|XIMStatusNothing;
fl_context->xic = XCreateIC(fl_context->xim,
XNInputStyle, style, 0);
}
.................
I get CJK-LyX working with this xforms. That is, I can input CJK
characters onto the main lyx window. However I cannot input
CJK-characters on the xforms box.
Now, with this setting I add your code in input.c:
................
/* toggle input method for CJK users */
if (key == XK_space) {
if (shiftkey_down(kmask) && ! sp->CJK_local_input) {
XPoint location;
int x, y, w, h;
XVaNestedList preedit_list;
location.x = ob->x;
location.y = ob->y;
preedit_list = XVaCreateNestedList( 0,XNSpotLocation,
&location,NULL);
XSetICValues(fl_context->xic,XNPreeditAttributes,preedit_list,0);
XFree(preedit_list);
}
.....................
Then, the library compiles well. However with the compiled library,
CJK-LyX dies with segfaults when I toggle(shift-space) to input
CJK-character onto "Edit->Find & Replace" box. The debug indicates
there's something wrong with "XSetICValues".
2. I guess the reason why I get segfaults on "XSetICValues" is that no
input contexts are created except the input style in fl_initialize in
flresource. So I tried a simple input context as follows:
..........................
if (fl_context->xim) {
int style = XIMPreeditPosition|XIMStatusNothing;
char **missing_list;
int missing_count;
char *def_string;
XFontSet fontset = XCreateFontSet(fl_display, DUMMY_FONT_NAME,
&missing_list,&missing_count, &def_string);
XPoint location;
location.x = 0;
location.y = 0;
XVaNestedList preedit_list;
XVaNestedList status_list;
preedit_list = XVaCreateNestedList( 0,
XNSpotLocation, &location,
XNFontSet, fontset,
NULL);
status_list = XVaCreateNestedList( 0,
XNFontSet, fontset,
NULL);
fl_context->xic = XCreateIC(fl_context->xim,
XNInputStyle, style,
XNPreeditAttributes, preedit_list,
NULL);
XFree(preedit_list);
XFree(status_list);
........................................
The problem is that with this xforms library (without your
change in input.c), I cannot input CJK-characters on the main lyx
window anymore. I guess this happens because this XIC settings conflict
with those in lyxim.C. If I toggle to input CJK-characters on the
"Edit->Find &..." box, however, it connects with my local input mehtod
and composing of characters occur at the position (0,0) as expected
(location.x = 0, ...) and the "space" puts the composed characters on
the box! Now I add your code in input.c as in "1" above. This time I
do not get segfaults as expected, but adding your code seems do
nothing!--- I still cannot input CJK-characters on the main lyx window
and the pre-composition of CJK-characters occurs at the position (0,0).
I'm really at a loss, now. How about you? I'm ccing this email to
Miyata. Maybe he has answers.
