Hello, I have a GtkTreeSelection "selection_categorie" linked to the treeview "article_tree" with gtk_tree_view_get_selection In the treeview "article_tree", I display the GtkTreeStore "store_article" with a GtkTreeModel *store = GTK_TREE_MODEL (store_article); GtkTreeIter *iter_categorie is the iter I'm lookking for. Compilation works fine. when I run gtk_tree_selection_get_selected (selection_categorie, &store, iter_categorie); I get the error: Program received signal SIGSEGV, Segmentation fault. 0xb7eaa943 in gtk_tree_selection_get_selected () from /usr/lib/libgtk-x11-2.0.so.0 Do you have an idea what's wrong ?
