New widget for a button that displays a folder selection in a standard
* evolution-folder-selector-button.c: New widget for a button that displays a folder selection in a standard form, and when clicked lets the user select a new folder. * Evolution-Shell.idl (FolderSelectionListener:notifySelected): Make this take an Evolution:Folder instead of a pair of uris. (Shell:getIconByType): New method to get the icon for a type from the folder type registry. * Evolution-common.idl (Folder): add "evolutionUri" to the folder structure. * Evolution-Storage.idl (StorageRegistry:getFolderByUri): get an Evolution:Folder for a given uri. * evolution-shell-client.c (evolution_shell_client_user_select_folder): Update this to reflect the IDL change: return a GNOME_Evolution_Folder instead of a pair of URIs. Make sure it always sets *@folder_return to %NULL if it fails (even if it's a g_return_if_fail). (evolution_shell_client_get_storage_registry_interface): New. (evolution_shell_client_get_pixbuf_for_type): New. Uses Shell_getIconByType, but caches results. * e-shell.c (folder_selection_dialog_folder_selected_cb): Update for API change. (Return a GNOME_Evolution_Folder.) (impl_Shell_getIconByType): Implement. * e-corba-storage-registry.c (impl_StorageRegistry_getFolderByUri): Implement. * evolution-storage.c (evolution_storage_new_folder): Add a (dummy) evolutionUri to the folder. * Makefile.am (libeshell_la_SOURCES): add evolution-folder-selector-button.c (eshellinclude_HEADERS): and .h svn path=/trunk/; revision=16352
