кодинг с ГТК2 в Анюте

Just give me your mail. I'll try to send you complete example. It takes 5 miute to do that.

Your problem is that you don't read your program output. Your *tv is really _not_ GTK_TEXT_VIEW.

Here is complete example. How you can build it

1. Save prj.glade in some dir and open it with glade-2.
2. Build project in glade-2 to get working project.
3. Replace file callbacks.c with given file
4. Learn gtk and enjoy.

notffeq@mail.ru - мой мыл, а я пока пойду пробовать код от anonymous (*) (2003-09-26 23:49:11.407262)

Теперь оно работает, но проблемы не кончились. Дело в том, что текст переменной text я гружу из файла с кодировкой cp1251. С переменной все впорядке - я специально выводил ее содержимое в консоль, чтоб убедится в этом. Но при попытке загрузить текст переменной в tv выдается ошибка:

(prog:17125): Gtk-CRITICAL **: file gtktextbuffer.c: line 543 (gtk_text_buffer_emit_insert): assertion `g_utf8_validate (text, len, NULL)' failed

Заглянул в докву по gtk2, там написано, что в функции gtk_text_buffer_set_text(GTK_TEXT_BUFFER(b),text,strlen(part_to_show)); переменная text должна быть utf8. Вопрос: ктонить знает как загрузить переменную не с utf8 (а с cp1251 или koi8-r) в етот GtkTextBuffer *b; ?

Have you ever heard about library functions? Read manual on glib.


/* Note: result should be freed with g_free() */
gchar *from_win_to_utf(gchar *text)
{
GError *err = NULL;
gint bytes_read, bytes_written;
gchar *result;
result = g_convert(text, strlen(text), "utf-8", "cp1251", 
             &bytes_read, &bytes_written, &err);

return result;
}
