====== xfdesktop: Port to GIO ====== ===== References to ThunarVFS ===== ==== main.c ==== Calls ''thunar_vfs_init()'' and ''thunar_vfs_shutdown()''. Those calls can be removed. ==== xfce-desktop.c ==== === xfce_desktop_setup_icon_view() === Use a ''GFile'' instead of a ''ThunarVfsPath'' when creating the file icon manager. Pass the ''GFile'' to the manager object instead of the ''ThunarVfsPath''. ==== xfdesktop-clipboard-manager.c ==== === XfdesktopClipboardPasteRequest === Use a ''GFile'' instead of the ''ThunarVfsPath'' for the ''target_path'' struct member. === xfdesktop_clipboard_manager_get_callback() === Make ''xfdesktop_file_utils_file_icon_list_to_path_list()'' return a list of ''GFile'' objects. Reuse ''thunar_g_file_list_to_string()'' instead of using ''thunar_vfs_path_list_to_string()''. Use ''g_list_foreach()'' and ''g_list_free()'' instead of ''thunar_vfs_path_list_free()''. ==== xfdesktop-file-icon.{c,h} ==== === xfdesktop_file_icon_finalize() === There's no need for cancelling jobs if we don't use jobs anymore. Instead we'll use the new D-Bus methods that have been added to Thunar. When using those we can just fire and forget. === xfdesktop_file_icon_activated() === We don't need the file info here. Just launch the file using Thunar's ''Launch()'' D-Bus method. Add an interface method ''get_file'' and make it return a ''GFile''. Use this ''GFile'' to compute the URI to be passed to ''Launch()''. Make the interface method ''peek_info'' return a ''GFileInfo''. ==== xfdesktop-file-icon-manager.{c,h} ==== === xfdesktop_file_icon_menu_rename() === Use Thunar's ''Rename()'' (or ''RenameFiles?'') D-Bus method. For this we only need the ''GFile'' of the icon, not the file info. Use ''xfdesktop_file_icon_get_file()'' instead of ''xfdesktop_file_icon_peek_info()''. === xfdesktop_file_icon_manager_trash_files() === Again, use ''xfdesktop_file_icon_get_file()'' instead of ''xfdesktop_file_icon_peek_info()'' to obtain the URIs of the files supposed to be trashed. === xfdesktop_file_icon_menu_mime_app_executed() === Use ''GAppInfo'' instead of ''ThunarVfsMimeApplication'' and call ''g_app_info_launch()'' instead of ''thunar_vfs_mime_handler_exec()''. Make sure to change the working directory before and after this call (similar to how Thunar does it). === xfdesktop_menu_item_from_mime_handler() === Replace this method with a similar one based on ''GAppInfo'' instead of ''ThunarVfsMimeApplication''. === xfdesktop_file_icon_menu_open_folder() === We don't need the ''ThunarVfsInfo'' here. Use ''xfdesktop_file_icon_get_file()'' instead of ''xfdesktop_file_icon_peek_info()''. Make ''xfdesktop_file_utils_open_folder()'' take a ''GFile'' instead of a ''ThunarVfsInfo''. === xfdesktop_file_icon_menu_open_desktop() === See the previous function. === xfdesktop_file_icon_menu_other_app() === Again, we only need the ''GFile'', not the file info, in order to obtain the file URI. Replace ''xfdesktop_file_icon_peek_info()'' with ''xfdesktop_file_icon_get_file()'' and ''ThunarVfsInfo''/''ThunarVfsPath'' with ''GFile''. === xfdesktop_file_icon_menu_properties() === Again, we only need the ''GFile'' to obtain the URI. Don't use the no-D-Bus-fallback properties dialog (what's it good for? Thunar should always be running for other parts of xfdesktop to be working anyway). === xfdesktop_file_icon_create_directory_error() === Remove this function. We'll create directories through the Thunar D-Bus API. We'll probably have to add another D-Bus method for creating directories. === xfdesktop_file_icon_menu_create_launcher() === Use a ''GFile'' instead of the ''ThunarVfsInfo'' and ''ThunarVfsPath'' to obtain the file URI. Feed exo-desktop-item-edit with the URI instead of a local path. The function ''launcher_dialog_item_button_clicked()'' in xfce4-panel/plugins/launcher/launcher-dialog.c has an example of how we can do this. === xfdesktop_file_icon_menu_create_folder() === Create the directory using a new Thunar D-Bus method instead of implementing this feature in xfdesktop internally. We'll have to create the D-Bus method first. It should be called ''CreateFolder()'' or ''CreateFile()'' (with a type parameter). Need to think about this a bit more. === xfdesktop_file_icon_create_file_error() === Remove this function. === xfdesktop_file_icon_interactive_job_ask() === Remove this function. === xfdesktop_file_icon_template_item_activated() === TODO: This needs more thought. Thunar implements the same functionality, so maybe we can reuse its implementation through D-Bus. If not, then at least the ThunarVFS stuff should be replaced with ''GFile'' and ''GFileInfo''. The calls to ''thunar_vfs_copy_file()'' and ''thunar_vfs_create_file()'' should be replaced with Thunar D-Bus method calls. === info_compare() === If this is still needed after the other refactorings, make it compare ''GFileInfo'' objects instead of ''ThunarVfsInfo'' structs. === xfdesktop_file_icon_menu_fill_template_menu() === Use ''GFile'', ''GFileEnumerator'' and ''GFileInfo'' instead of the corresponding ThunarVFS structures. Maybe we can reuse some code from Thunar implementing the same thing. === xfdesktop_file_icon_manager_populate_context_menu() === Use ''GFileInfo'' instead of ''ThunarVfsInfo'' and ''GFile'' instead of ''ThunarVfsPath''. Use ''GAppInfo'' instead of ''ThunarVfsMimeDatabase'' and ''ThunarVfsMimeHandler''/''ThunarVfsMimeApplication''. === xfdesktop_file_icon_manager_add_icon() === Use ''GFile'' instead of ''ThunarVfsInfo''. === xfdesktop_file_icon_manager_add_regular_icon() === Use ''GFileInfo'' to query the content type and ''GFile'' instead of ''ThunarVfsPath'' to query the file path passed to ''XfceRc''. === xfdesktop_file_icon_manager_add_volume_icon() === Use ''GVolume'' instead of ''ThunarVfsVolume''. === xfdesktop_file_icon_manager_vfs_monitor_cb() === Replace this with a monitor callback for ''GFileMonitor''. === xfdesktop_file_icon_manager_listdir_infos_ready_cb() === This function will have to be replaced with something similar because we cannot use the list dir job from ThunarVfsJob anymore. === xfdesktop_file_icon_manager_listdir_finished_cb() === This function will have to be replaced with something similar because we cannot use the list dir job from ThunarVfsJob anymore. === xfdesktop_file_icon_manager_listdir_error_cb() === This function will have to be replaced with something similar because we cannot use the list dir job from ThunarVfsJob anymore. === xfdesktop_file_icon_manager_load_desktop_folder() === Asynchronously load the folder using ''GFileEnumerator''. === xfdesktop_file_icon_manager_volume_changed() === Replace this function with a similar one based on ''GVolumeMonitor''. === xfdesktop_file_icon_manager_add_removable_volume() === The calls to ''thunar_vfs_is_removable()'' and ''thunar_vfs_volume_is_present()'' need to be replaced with something similar based on ''GVolume''. Thunar has the same problem solved with this code: * http://git.xfce.org/xfce/thunar/tree/thunar/thunar-gio-extensions.c#n389 * http://git.xfce.org/xfce/thunar/tree/thunar/thunar-gio-extensions.c#n455 === xfdesktop_file_icon_manager_volumes_added() === This will be replaced with a handler for the ''volume-added'' signal of ''GVolumeMonitor'' which should call ''xfdesktop_file_icon_manager_add_removable_volume()'' as well. === xfdesktop_file_icon_manager_volumes_removed() === Similar to the previous function, this one should be replaced with one that handles a single ''GVolume'' volume only. === xfdesktop_file_icon_manager_load_removable_media() === Use the ''GVolumeMonitor'' here and connect to the right signals. We'll need new callbacks for some of them. === xfdesktop_file_icon_manager_remove_removable_media() === Needs to iterate over the volumes hash table, disconnect from all returned volumes, destroy all volume icons and disconnect from the ''GVolumeMonitor''. === xfdesktop_file_icon_manager_real_init() === Get rid of the ''ThunarVfsMimeDatabase'' and the global ''ThunarVfsVolumeManager''. The hash table needs to use either URIs or ''GFile'' as well as the right hash and equal functions for them. URIs are easier due to the availability of string hash and equal functions, I guess. We'll have to change the ''ThunarVfsInfo'' parameter of ''xfdesktop_regular_file_icon_new()'' to a ''GFile'' or ''GFileInfo''. We can use ''g_file_new_for_path()'' instead of ''thunar_vfs_info_new_for_path()'' here when creating the ''GFile'' for the desktop folder, if the ''folder'' member isn't a ''GFile'' already. === xfdesktop_file_icon_manager_fini() === The counterpart to the previous function. Same deal. === xfdesktop_file_icon_manager_drag_drop() === Use '''xfdesktop_file_icon_peek_file()'' instead of ''..._peek_info()''. The file type can then be determined with ''g_file_query_file_type()''. Use ''g_file_get_child()'' instead of ''thunar_vfs_path_relative()'' and ''g_file_get_uri()'' instead of ''thunar_vfs_path_dup_uri()''. === xfdesktop_file_icon_manager_drag_data_received() === Use ''..._peek_file()'' **and** ''..._peek_info()'' (we need both this time around) and ''GFile'' functions instead of ''ThunarVfsPath''. To convert the string list into a list of ''GFile'' objects, we can use something similar to Thunar's solution: * http://git.xfce.org/xfce/thunar/tree/thunar/thunar-gio-extensions.c#n262 We'll need a bit of custom code to execute the executable target file with the dropped files as parameters. There are two possibilities: either the target is a desktop entry, then we can parse it into a ''GDesktopAppInfo'', or it is a regular executable file, then we can simply spawn it (make sure to pass the file parameters and implement startup notification). The code block dealing with jobs needs to be reworked around ''GFile'', ''GFileInfo'' and the Thunar D-Bus API completely. Maybe danielm's branch implements this already? === xfdesktop_file_icon_manager_drag_data_get() === We need to replace ''xfdesktop_file_utils_file_icon_list_to_path_list()'' with something like ''xfdesktop_file_utils_file_icon_list_to_g_file_list()'' and then call ''g_file_list_to_string()'' instead of ''thunar_vfs_path_list_to_string()''. Again, Thunar can serve as an inspiration here: * http://git.xfce.org/xfce/thunar/tree/thunar/thunar-gio-extensions.c#n295 === xfdesktop_file_icon_manager_new() === Change the ''ThunarVfsPath'' parameter to a ''GFile''. That's all. === _XfdesktopFileIconManagerPrivate === Change the ''ThunarVfsPath'' folder member to a ''GFile''. Replace the ''ThunarVfsMonitor'' with a ''GVolumeMonitor'' and remove the ''ThunarVfsMonitorHandle''. Remove the ''ThunarVfsJob *list_job'' member. === xfdesktop_file_icon_manager_class_init() === Alter the "folder" property so that it becomes an object property using the ''G_TYPE_FILE'' object type. === xfdesktop_file_icon_manager_set_property() === Change the "folder" property code to reflect the changes to the property type made in the class_init function. === xfdesktop_file_icon_manager_get_property() === Same here, see above. === xfdesktop_file_icon_manager_finalize() === Use ''g_object_unref()'' instead of ''thunar_vfs_path_unref()''. === xfdesktop_file_icon_manager_check_create_desktop_folder() === Replace the code with something similar based on ''GFile'', ''g_file_query_exists()'', ''g_file_query_file_type()'' and ''g_file_make_directory()''. ==== xfdesktop-file-properties-dialog.{c,h} ==== Remove entirely. We'll re-use Thunar's properties dialog via its D-Bus API. ==== xfdesktop-file-utils.{c,h} ==== === xfdesktop_file_utils_interactive_job_ask() === Remove. We'll no longer implement anything job-related in xfdesktop itself. === xfdesktop_file_utils_handle_fileop_error() === Remove as well. === xfdesktop_file_utils_get_file_kind() === If this is still needed after refactoring, then make it take a ''GFileInfo'' and rewrite the checks based on ''GFileInfo'' attributes. === xfdesktop_file_utils_file_icon_list_to_path_list() === Replace with a function called ''xfdesktop_file_utils_file_icon_list_to_g_file_list()'' that creates a list of ''GFile'' objects. === xfdesktop_file_utils_get_fallback_icon() === No longer needed, remove. ''g_file_info_get_icon()'' always returns a valid ''GIcon''. === xfdesktop_file_utils_get_file_icon() === We have two options here: either remove and use ''g_file_info_get_icon()'' or make it load and return a ''GdkPixbuf'' from the ''GIcon''. TODO We'll have to investigate where ''xfdesktop_file_utils_get_file_icon()'' is being used and how. === xfdesktop_file_utils_launch_fallback() === Remove. We don't use a D-Bus fallback here as we rely on the D-Bus API of Thunar so hard that we can't provide any real functionality without it anyway. === xfdesktop_file_utils_display_folder_cb() === Remove fallback code. ==== xfdesktop-regular-file-icon.{c,h} ==== === _XfdesktopRegularFileIconPrivate === Replace the ''ThunarVfsInfo *info'' member with ''GFile'' and ''GFileInfo'' members. === xfdesktop_regular_file_icon_peek_info() === Return a ''GFileInfo''. === xfdesktop_regular_file_icon_update_info() === TODO: Replace the ''ThunarVfsInfo'' parameter with ''GFileInfo''. Maybe we also need to add a ''GFile'' parameter because ''GFileInfo'' contains no path information. === xfdesktop_delete_regular_file_finished() === Remove. === xfdesktop_regular_file_icon_finalize() === Call ''g_object_unref()'' instead of ''thunar_vfs_info_unref()''. Also release the new ''GFile'' member. === xfdesktop_regular_file_icon_tfi_init() === Update this to Thunarx 2. Need to set ''iface->get_file_info'', ''iface->get_filesystem_info'' and ''iface->get_location''. === xfdesktop_regular_file_icon_peek_pixbuf() === Need to rewrite this to make use of ''g_file_get_icon()'' and tumbler. Maybe a new thumbnailer or icon factory class like in thunar could be introduced. === xfdesktop_regular_file_icon_get_allowed_drag_actions() === Use ''GFileInfo'' instead of ''ThunarVfsInfo''. Instead of ''ThunarVfsInfo'' flags we have to query ''GFileInfo'' attributes to determine the readable/writable state of the target icon. === xfdesktop_regular_file_icon_get_allowed_drop_actions() === See the previous function. === xfdesktop_regular_file_icon_drag_job_error() === I don't think we need this any longer. Thunar will display errors for us. === xfdesktop_regular_file_icon_interactive_job_ask() === Remove. === xfdesktop_regular_file_icon_drag_job_finished() === Remove. === xfdesktop_regular_file_icon_do_drop_dest() === Rewrite the code based on ''GFileInfo'' and ''GFile''. Use the Thunar D-Bus API to launch executable files. Use a NULL check with ''g_file_get_parent()'' to replace the call to ''thunar_vfs_path_is_root()''. Instead of ''thunar_vfs_move_file()'', ''thunar_vfs_copy_file()'' etc. use the Thunar D-Bus API. Instead of implement the Thunar D-Bus client manually we could rely on code generation. === xfdesktop_regular_file_icon_peek_tooltip() === What we need is to read the last modification time, the file type and a human readable version of the size of the file. There are attributes for the modification time, the file type and the file size in ''GFileInfo''. To humanize the file time we can use something similar to [[http://git.xfce.org/xfce/thunar/tree/thunar/thunar-util.c#n140|what Thunar is doing]], for the file size we can use ''g_format_size_for_display()''. === xfdesktop_regular_file_can_write_parent() === Here we can simply rewrite the code to use ''GFile'' and ''GFileInfo''. === xfdesktop_delete_file_error() === Remove. === xfdesktop_delete_file_finished() === Remove. === xfdesktop_regular_file_icon_delete_file() === Instead of ''thunar_vfs_unlink_file()'', use the Thunar D-Bus API here. Fire and forget. === xfdesktop_regular_file_icon_rename_file() === See previous function. === xfdesktop_regular_file_icon_peek_info() === Change the return type to ''GFileInfo''. === xfdesktop_regular_file_icon_update_info() === TODO: Check how and where this function is being used and what we can do in order to replace the ''ThunarVfsInfo'' parameter. === xfdesktop_regular_file_icon_new() === Add a ''GFile'' parameter, update the code to use ''g_object_ref()'' instead of ''thunar_vfs_info_ref()''. ==== xfdesktop_special_file_icon.{c,h} ==== === _XfdesktopSpecialFileIconPrivate === TODO === xfdesktop_special_file_icon_finalize() === TODO === xfdesktop_special_file_icon_tfi_init() === TODO === xfdesktop_special_file_icon_get_allowed_drag_actions() === TODO: we no longer need the thunar-vfs workaround I think. === xfdesktop_special_file_icon_get_allowed_drop_actions() === TODO === xfdesktop_special_file_icon_drag_job_error() === TODO === xfdesktop_special_file_icon_interactive_job_ask() === TODO === xfdesktop_special_file_icon_drag_job_finished() === TODO === xfdesktop_special_file_icon_do_drop_dest() === TODO === xfdesktop_special_file_icon_peek_tooltip() === TODO === xfdesktop_special_file_icon_peek_info() === TODO === xfdesktop_special_file_icon_new() === TODO ==== xfdesktop-volume-icon.{c,h} ==== === _XfdesktopVolumeIconPrivate === TODO === xfdesktop_volume_icon_finalize() === TODO === xfdesktop_volume_icon_tfi_init() === TODO === xfdesktop_volume_icon_volume_changed_cb() === TODO === xfdesktop_volume_icon_peek_pixbuf() === TODO === xfdesktop_volume_icon_peek_label() === TODO === xfdesktop_volume_icon_get_allowed_drag_actions() === TODO === xfdesktop_volume_icon_get_allowed_drop_actions() === TODO === xfdesktop_volume_icon_drag_job_error() === TODO === xfdesktop_volume_icon_interactive_job_ask() === TODO === xfdesktop_volume_icon_drag_job_finished() === TODO === xfdesktop_volume_icon_do_drop_dest() === TODO === xfdesktop_volume_icon_peek_tooltip() === TODO === xfdesktop_volume_icon_menu_toggle_mount() === TODO === xfdesktop_volume_icon_menu_eject() === TODO === xfdesktop_volume_icon_populate_context_menu() === TODO === xfdesktop_volume_icon_peek_info() === TODO === xfdesktop_volume_icon_update_info() === TODO === xfdesktop_volume_icon_activated() === TODO === xfdesktop_volume_icon_new() === TODO === xfdesktop_volume_icon_peek_volume() === TODO
