From 86b700d089bfb9565c3792ff3df1a1ac6cf225c3 Mon Sep 17 00:00:00 2001 From: Dan Winship Date: Thu, 14 Mar 2002 22:22:35 +0000 Subject: Support for delayed filling-in of storages/folders. * Evolution-Storage.idl (StorageListener): add notifyHasSubfolders, to announce that a folder has currently- unknown subfolders. (Storage): add asyncOpenFolder, to request that previously- announced subfolders be filled in. * evolution-storage.c (impl_Storage_async_open_folder): emit OPEN_FOLDER. (evolution_storage_has_subfolders): Implement by calling notifyHasSubfolders on all of its listeners. * evolution-storage-listener.c (impl_GNOME_Evolution_StorageListener_notifyHasSubfolders): emit HAS_SUBFOLDERS. * e-corba-storage.c (impl_StorageListener_notifyHasSubfolders): Implement by calling e_storage_has_subfolders. (async_open_folder): Implement by calling asyncOpenFolder on the CORBA storage. * e-storage.c (EStoragePrivate, init, destroy): Keep a list of pseudofolders representing un-filled-in subtrees. (impl_async_open_folder): No-op default implementation (e_storage_async_open_folder): New function to request that un-filled-in subtrees be filled in. (e_storage_new_folder): If the new folder's parent has an "un-filled-in children" pseudofolder, remove it. (e_storage_has_subfolders): New function to note that a folder has unknown children. If the folder previously was marked as having real children, remove them, and emit CLOSE_FOLDER to reset it back to an a "unknown subfolders" state. * e-storage-set.c (make_full_path): Make this deal with path being "/", since that case gets used from storage_close_folder_cb sometimes. (storage_close_folder_cb): Proxy EStorage's CLOSE_FOLDER signal. (storage_set_view_folder_opened): Handle EStorageSetView's FOLDER_OPENED signal by calling e_storage_async_open_folder. * e-storage-set-view.c (etree_fill_in_children): If the given node is its parent's first child, emit FOLDER_OPENED for the parent. (close_folder_cb): Handler for EStorageSet's CLOSE_FOLDER signal. Ask the model to close that node. (e_storage_set_view_construct): Set the default expanded state for the tree to FALSE rather than TRUE, to prevent unwanted expansion of delayed nodes. (This only affects the very first time the tree is displayed anyway: after that its state is loaded off disk.) * e-shell.c (e_shell_construct): Register the "noselect" type with the folder type registry, so icon lookups on placeholder folders will work. svn path=/trunk/; revision=16169 --- shell/e-storage-set.h | 1 + 1 file changed, 1 insertion(+) (limited to 'shell/e-storage-set.h') diff --git a/shell/e-storage-set.h b/shell/e-storage-set.h index 16e717df16..6bfa1129e5 100644 --- a/shell/e-storage-set.h +++ b/shell/e-storage-set.h @@ -65,6 +65,7 @@ struct _EStorageSetClass { void (* new_folder) (EStorageSet *storage_set, const char *path); void (* updated_folder) (EStorageSet *storage_set, const char *path); void (* removed_folder) (EStorageSet *storage_set, const char *path); + void (* close_folder) (EStorageSet *storage_set, const char *path); }; -- cgit
