Hi, Micah
There are some other bugs, we fixed.
1. in widget/textedit_logical.c, old code in most skins cause pgserver crashed.
#ifdef CONFIG_HANDINFO_FIXED
g_error text_backend_build ( text_widget * widget,
s16 w,
s16 h ) {
#else
g_error text_backend_build ( text_widget * widget,
u16 w,
u16 h ) {
#endif
2.in widget/textedit_logical.c, we must judge if the buffer had chars.
g_error text_backend_set_selection ( text_widget * widget,
struct pgstring * text ) {
g_error e;
#ifdef CONFIG_TEXTEDIT_WCHART
wchar_t * wBuffer;
#ifdef CONFIG_HANDINFO_FIXED
if (!text->buffer || text->num_chars == 0)
{
return success;
}
#endif
....
}
3. in gcore/pgstring.c pgstr_utf8_seek function, we handle negative char_num, that be
used in textbox widget if we want to support utf8 code (Chinese). but this code is vey
ugly and slow and it can work.
void pgstr_utf8_seek(const struct pgstring *str, struct pgstr_iterator *p, s32
char_num, int whence) {
int num = 0, savenum = 0;
struct pgstr_iterator temp_iterator;
switch (whence) {
case PGSEEK_SET:
p->offset = 0;
break;
case PGSEEK_END:
#ifdef CONFIG_HANDINFO_FIXED
if (str->num_chars == 0)
p->offset = 0;
else
#endif
p->offset = str->num_chars - 1;
break;
}
/* FIXME: handle negative char_num by sanit Handinfo Ltd.*/
#ifdef CONFIG_TEXTBOX_SUPPORT_UTF8
if (char_num >= 0)
{
#endif
while (char_num) {
if (!pgstring_decode(str,p))
return;
char_num--;
}
#ifdef CONFIG_TEXTBOX_SUPPORT_UTF8
}else
{
if ((num = char_num + str->num_chars) <= 0)
p->offset = 0;
else
{
temp_iterator = *p;
temp_iterator.offset = 0;
/*FIXED ME this is a very urgly code, sanit */
savenum = str->num_chars;
while (savenum) {
if (!pgstring_decode(str,&temp_iterator))
return;
if (temp_iterator.offset == p->offset)
{
break;
}
savenum--;
}
if (savenum == 0)
return;
num = str->num_chars - savenum;
temp_iterator.offset = 0;
while (num) {
if (!pgstring_decode(str,&temp_iterator))
return;
num--;
}
*p = temp_iterator;
}
}
#endif
}
