Re: GtkTreeIter validity.

[Harring Figueiredo <harringf yahoo com>]

 For those who care, I found a solution ( might be dirty, but easy. :)

  some_func()
  {
     gboolean valid;
 
     valid = gtk_tree_store_get_iter_first(iter);
      while(valid)
      {
         if(some_crtieria == TRUE)
           {
             gtk_list_store_remove(model, iter); 
               valid = ( iter.stamp != 0 ? TRUE : FALSE);  <====== this did it.
               continue;
            }
         
         valid = gtk_tree_model_iter_next(..., iter);
      }
  }
