--- Comment #3 from Lunxian <lunxian@xxxxxxxxx> 2009-06-06 12:41:19 PDT ---
I read the source code, and it seems that the "Sort treeview" is the core to
consume performance of input "radius.", is it?
The code is in function filter_autocomplete_new of filter_autocomplete.c :
/* Sort treeview */
model = gtk_tree_view_get_model(GTK_TREE_VIEW(treeview));
order = GTK_SORT_ASCENDING;
if(model)
gtk_tree_sortable_set_sort_column_id(GTK_TREE_SORTABLE(model), 0, order);
backspacing performance is not same as inputing "radius." directly, I will
review the function filter_autocomplete_handle_backspace(), no problem found.
Maybe "Empty list" is poor performance?
/* Empty list */
store = GTK_LIST_STORE(gtk_tree_view_get_model(GTK_TREE_VIEW(list)));
gtk_list_store_clear(store);
