** Fix for bug #352695
2008-08-11 Milan Crha <mcrha@redhat.com> ** Fix for bug #352695 * widgets/table/e-tree-table-adapter.h: (e_tree_table_adapter_save_expanded_state_xml), (e_tree_table_adapter_load_expanded_state_xml): * widgets/table/e-tree-table-adapter.c: (e_tree_table_adapter_save_expanded_state_xml), (e_tree_table_adapter_save_expanded_state), (e_tree_table_adapter_load_expanded_state_xml), (e_tree_table_adapter_load_expanded_state): * widgets/table/e-tree.h: (e_tree_save_expanded_state_xml), (e_tree_load_expanded_state_xml): * widgets/table/e-tree.c: (e_tree_save_expanded_state_xml), (e_tree_load_expanded_state_xml): Be able to store expanded state also in memory, not only on the disk. * mail/message-list.c: (struct _MessageListPrivate), (save_tree_state), (load_tree_state), (on_model_row_changed), (message_list_init), (message_list_construct), (struct _regen_list_msg), (regen_list_done), (regen_list_free), (mail_regen_list): Be able to recognize whether there has been any change on any row in a list and save expanded state only in case there was any change. Also use in-memory storing of the expanded state in case we do not want to rewrite full view It's for searches only, and it's not stored between sessions. svn path=/trunk/; revision=35953
