Hi everybody,
I am stuck with a segmentation fault caused by a treeview and I have pent hours trying to figure out what's wrong with no success.
Here is how I create the model (I simplified the code... but this version crashes as well...) while (item) { gtk_list_store_append (store, &iter); gtk_list_store_set (store, &iter, MIME_TYPES_TO_SKIP_COLUMN_STATE, 0 , MIME_TYPES_TO_SKIP_COLUMN_MIME_TYPE, test, -1);
item=g_list_next(item); }
That looks OK.
The segmentation fault happens when I remove an item with this code:
gtk_tree_model_get (model,&iter,
0, &state, 1, &mime_type,
-1);
Why are you using constants such as (MIME_TYPES_TO_SKIP_COLUMN_STATE and MIME_TYPES_TO_SKIP_COLUMN_MIME_TYPE) in the code that adds data but referencing them by number here. This could lead to problems if the constants change later.
if (gtk_tree_selection_get_selected (listSelection, NULL, &iter)) { gtk_list_store_remove (GTK_LIST_STORE (model), &iter); }
Here is what ddd says: (gtktalog:5396): Gtk-CRITICAL **: file ../../gtk/gtkliststore.c: line 566 (gtk_list_store_get_value): assertion `GTK_LIST_STORE (tree_model)->stamp == iter->stamp' failed
The error seems to indicate that you modified the model after retrieving the iterator, which invalidates the iterator.
