Hi
I am using genlist, I have a "double_label" genlist in my Application:
e_music_playlist_append(Evas_Object *playlist_show, TrackProperties
> *properties, int list_id)
{
Listitem *listitem;
> itclass.item_style = "double_label";
itclass.func.label_get = _gl_label_get;
itclass.func.icon_get = _gl_icon_get;
itclass.func.state_get = _gl_state_get;
itclass.func.del = _gl_del;
>
> listitem = E_MUSIC_NEW(Listitem, 1);
listitem->pro = properties;
listitem->item = elm_genlist_item_append(playlist_show, &itclass,
listitem, NULL/* parent */, ELM_GENLIST_ITEM_NONE,
> _list_sel, (int *)list_id/* func data */ );
> /* it will do _gl_label_get two times, but wen we do _gl_label_get in the
> second time ,listitem may has been free! */
// free( listitem );
}
so, I expected to got two times of call of _gl_label_get:
char *
_gl_label_get(const void *data, Evas_Object *obj, const char *part)
{
const Listitem *tit = data;
char buf[PATH_MAX];
printf("BUF:%s\n", tit->pro->title);
if (!strcmp(part, "elm.text"))
{
snprintf(buf, sizeof(buf), "%s", tit->pro->title);
> }
else if (!strcmp(part, "elm.text.sub"))
{
snprintf(buf, sizeof(buf), "%s", tit->pro->artist);
}
return strdup(buf);
}
BUT, i have got four!

SO, is it normal to get this? How can I fix the err? I don't want to store
all the listitem items in the memory statically.
Help me. thanks.
