2004-07-08 Federico Mena Quintero <federico@ximian.com> Fix #139290: * gtk/gtkfilesystemmodel.c (_gtk_file_system_model_new): Add a GError argument. Do check for errors when getting the GtkFileFolder: get the folder and read the children before actually creating the model. Removed obsolete code that handled roots-changed on the file system. (file_model_node_get_info): Assert that we don't reach the old case to display file system roots. (roots_changed_callback): Removed. * gtk/gtkfilechooserdefault.c (set_list_model): Add a GError argument, and a boolean return value. Return an error if we cannot create the file system model. On error, set a NULL model on the tree. (gtk_file_chooser_default_set_current_folder): Use the error value from set_list_model(). (gtk_file_chooser_default_set_property): Set the show_hidden property only if the browse_files_model exists. (gtk_file_chooser_default_unselect_path): Only operate if the browse_files_model exists. (check_preview_change): Check whether we have the sort_model. (change_folder_and_display_error): Copy the path we get passed before using it. There's a comment in there that explains why we need to copy it; basically, if the passed path belongs to the model, the model may go away in the middle of this function and we'll be left with a dangling pointer. (install_list_model_filter): Assert that the model is not NULL. (set_current_filter): Check whether the model exists. * gtk/gtktreeselection.c (gtk_tree_selection_get_selected): Don't g_return_if_fail if the model is NULL. (gtk_tree_selection_get_selected_rows): Likewise. (gtk_tree_selection_count_selected_rows): Likewise. (gtk_tree_selection_selected_foreach): Likewise. (gtk_tree_selection_path_is_selected): Likewise; rather just return FALSE. (gtk_tree_selection_select_all): Likewise. (gtk_tree_selection_unselect_all): Likewise. (gtk_tree_selection_select_range): Do g_return_if_fail() if the model is NULL. (gtk_tree_selection_unselect_range): Likewise. * gtk/gtkfilesystemunix.c (fill_in_names): Return immediately if g_dir_open() fails: there is no need to set the error ourselves, as g_dir_open() already does it.
