Hi All,
I am confused about GList. My application is parsing a file and creating
midi data with it. I am using GList to store the midi data. I have
created a GtkListStore to view the parsed data (to insure I am parsing
the data properly). So, below I iterate through the GList and "copy"
the data into a tree view. But, I am shocked to see that after I
iterate through the GList, I cannot iterate through the list again. I
have debugged the list after the iteration with g_list_length(events)
which shows the list length at 0. What is up with this? The first
while loop has data, the second while loop has not data. The code is
below-->
GtkTreeIter tree_iter;
events = g_list_reverse(events);
events = g_list_first(events);
while(events)
{
gtk_list_store_append (list_store, &tree_iter);
struct midi_event *me = events->data;
gtk_list_store_set(list_store, &tree_iter,
0, me->time_stamp,
1, me->event_type,
2, me->message1,
3, me->message2,
-1);
events = g_list_next(events);
}
/// this is where the list appears to be empty!!!!
events = g_list_first(events);
while(events)
{
g_print("midi event \n");
events = g_list_next(events);
}
Thanks for any help!
