Re: number of entries in GtkCombobox

2006-09-19 Thread Lance Dillon 
I'm not sure I like this answer, it seems to be way to much for this question, 
but it looks like the best way to do it is to get a GtkTreeIter with 
gtk_tree_model_get_iter_first(), then walk the list with 
gtk_tree_model_iter_next(), counting up the number of rows:

GtkTreeIter iter;
int num,v;
GtkTreeModel *m;
m=gtk_combo_box_get_model(combo_box);
v=gtk_tree_model_get_iter_first(m,iter);
if (v) {
  num=1;
  while (v=gtk_tree_model_iter_next(m,iter))
num++;
} else
  num=0;

Hi.
How do I get the number of entries in GtkComboBox (created with
gtk_combo_box_new_text() )?

Okay, that's better.  I didn't see the special case.
