求助--Gtk 开发的一个词典程序, 有点问题

sihan

自己作的一个词典程序, 在命令行正常执行. 用 Glade 作了个界面 . 执行时却只能
显示单词, 词性, 音标等英文信息. 而不能显示词典库里的中文解释.

[code:1]
[sihan@localhost src]$ ./test01

(test01:18132): Gtk-CRITICAL **: file gtktextbuffer.c: line 543 (gtk_text_buffer_emit_insert): assertion `g_utf8_validate (text, len, NULL)' failed
[/code:1]

用 Gdb 调试:
[code:1]
(gdb) b callbacks.c :72
Breakpoint 1 at 0x804a6ce: file callbacks.c, line 72.
(gdb) r
Starting program: /home/sihan/program/gtk/test04/src/test01

Breakpoint 1, on_button_search_clicked (button=0xbffd53a0, user_data=0x0)
    at callbacks.c:72
72              print_word(words, textview1);
(gdb) p words.node->exp
$1 = 0x92c85d8 "离去, 走, 进行, 变成, 趋于, 达到, 求助于, 诉诸"
(gdb)
[/code:1]
说明已经找到了. 下面是textview1 中显示的信息:
[code:1]
go

^Eu
vi.
                                                                        ------>这里没有解释项
[/code:1]

这是部分代码:
[code:1]
void
on_button_search_clicked                     (GtkButton       *button,
        gpointer         user_data)
{

    GtkWidget *textview1 = lookup_widget (GTK_WIDGET(button), "textview1");
    GtkWidget *entry1 = lookup_widget (GTK_WIDGET(button), "entry1");
    GtkTextBuffer *buffer;
    GtkTextIter iter;
    gchar *word;
    WORD words;

    init_node(&(words.node));
    word = gtk_entry_get_text(GTK_ENTRY(entry1));
    //*********************************************************
    char confit_file_name[] = "/home/sihan/bin/confit.txt";
    char path[80];
    char num = 'A';
    FILE *fp;
    int i;

    buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW(textview1));
    gtk_text_buffer_get_iter_at_offset(buffer, &iter, 0);
   
    if( read_file(confit_file_name, path, DICT_DIR_EC, num) ==0)
    {
        printf("please confit confit file !\n");
        exit(1);
    }

    i = strchr(path, '.') - path -1;
    path[i] = tolower(word[0]);

    if((fp=fopen(path, "r")) ==NULL)
    {
        printf("\nDic file open error !\n\n");
        exit(1);
    }

    while(!feof(fp))
    {
        if(myread(&words, fp, word) == 0)
            break;
        if( strcmp(words.word, word) == 0)
            break;
        else
        {  
            free(words.word);
            words.word = NULL;
        }
    }
    fclose(fp);

    if(words.word == NULL)
    {
        gtk_text_buffer_insert( buffer, &iter, "Word Unfinded\n", -1);
    }
    else
    {
        print_word(words, textview1);
        free_word(&words);
    }
    free(word);
    word = NULL;
}

void print_word(WORD words, gpointer *textview1)
{
    WNODE *p;
    GtkTextBuffer *buffer;
    GtkTextIter iter;
   
    buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW(textview1));
    gtk_text_buffer_get_iter_at_offset(buffer, &iter, 0);
   
    gtk_text_buffer_insert( buffer, &iter, "\n", -1);
    gtk_text_buffer_insert( buffer, &iter, words.word, -1);
    gtk_text_buffer_insert( buffer, &iter, "\n", -1);
    gtk_text_buffer_insert( buffer, &iter, "-------------------------\n", -1);
    gtk_text_buffer_insert( buffer, &iter, words.node->ps, -1);
    gtk_text_buffer_insert( buffer, &iter, "\n", -1);
    gtk_text_buffer_insert( buffer, &iter, words.node->pos, -1);
    gtk_text_buffer_insert( buffer, &iter, "\n", -1);
    gtk_text_buffer_insert( buffer, &iter, "", -1);
    gtk_text_buffer_insert( buffer, &iter, words.node->exp, -1);
    gtk_text_buffer_insert( buffer, &iter, "\n", -1);

}

我觉得可能是汉子字符的问题, 但是不知到怎么转换 g_convert() 这个函数怎么用?

还有一个问题:
[code:1]
怎么在textview里改变文字的字体, 因为音标那一项要用金山的音标字体.
[/code:1]

mozilla

是编码转换问题，gtk2内部处理用的是utf8编码，glib有现成的转换函数，好像是g_utf8_from_local，记不太清楚，你到glib头文件里找找utf8

sihan

还有个问题, 怎么在 textview 中设置输出的字体呢???

mozilla

修改控件的style属性
