Hi, In my app there are 3 elements/pointers (elem) saved on: GPtrArray *array; With: g_ptr_array_add (array, (gpointer) elem); "elem" is defined like this: struct _elem_struct { GtkWidget *scrolledwindow; GtkWidget *view; GtkListStore *table; }; typedef struct _elem_struct elem_struct; elem_struct elem; And allocated by: elem = g_new0 (elem_struct, 1); new_elem(elem); ..... ..... void new_elem (elem_struct *elem) { GtkTreeSelection *selection; GtkCellRenderer *cell; GtkTreeViewColumn *column; /* scrolled window */ elem->scrolledwindow = gtk_scrolled_window_new (NULL, NULL); gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (elem->scrolledwindow), GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC); gtk_scrolled_window_set_shadow_type (GTK_SCROLLED_WINDOW (elem->scrolledwindow), GTK_SHADOW_OUT); elem->view = gtk_tree_view_new (); selection = gtk_tree_view_get_selection (GTK_TREE_VIEW (elem->view)); gtk_tree_selection_set_mode (selection, GTK_SELECTION_SINGLE); elem->table = gtk_list_store_new (2, G_TYPE_STRING, G_TYPE_STRING); gtk_tree_view_set_model (GTK_TREE_VIEW (elem->view), GTK_TREE_MODEL (elem->table)); cell = gtk_cell_renderer_text_new (); column = gtk_tree_view_column_new_with_attributes("Header Title", cell, "text", i, NULL); gtk_tree_view_column_set_resizable(GTK_TREE_VIEW_COLUMN(column), TRUE); gtk_tree_view_append_column(GTK_TREE_VIEW(elem->view), column); gtk_widget_show (elem->view); gtk_container_add (GTK_CONTAINER (elem->scrolledwindow), elem->view); } 1) When program is closed, it deallocates memory like this: for (i=0; i < 3; i++) g_free (g_ptr_array_index(array, i)); g_ptr_array_free (array,FALSE); Is it enough to dealloc memory? (I got SEGFAULT). 2) When it's used g_ptr_array_remove_index(elem,i) array->len is automatically updated (it seems not)?
