Added fields for the shortcuts tree and its model. (create_file_list):
2003-09-30 Federico Mena Quintero <federico@ximian.com> * gtkfilechooserimpldefault.c (struct _GtkFileChooserImplDefault): Added fields for the shortcuts tree and its model. (create_file_list): Don't call gtk_tree_view_column_set_sort_column_id() twice. (create_shortcuts_model): New function. (list_icon_data_func): Use an ICON_SIZE macro instead of a hardcoded value. (list_row_activated): Use _gtk_file_chooser_set_current_folder_path() to avoid converting the GtkFilePath to a URI string. (gtk_file_chooser_impl_default_set_current_folder): Select the appropriate item from the shortcuts list when the current folder changes, to let the user know where he is. (tree_selection_changed): Likewise. * gtkfilesystem.h (struct _GtkFileSystemIface): Added methods for ::supports_shortcuts(), ::list_shortcuts(), ::set_shortcuts().
