Fix bug #215... desensitize menu items based on the number of selected

2001-08-09  Peter Williams  <peterw@ximian.com>

	Fix bug #215... desensitize menu items based on the number of
	selected messages (and whether there's a message in the pane)

	* folder-browser-ui.c (folder_browser_ui_add_message): Sensitize
	the menu items appropriately based on the old state.
	(fbui_sensitize_items): New function. Set the sensitivity of a
	list of commands.
	(folder_browser_ui_set_selection_state): New function. Move the FB
	to a new state of selected-ness, and sensitize menu items
	appropriately.
	(folder_browser_ui_message_loaded): New function. When notified
	that a message has been loaded, sensitize some menu items.

	* folder-browser-ui.h: Prototype new functions.

	* folder-browser.h: New enumeration,
	FolderBrowserSelectionState, that records the previous state
	of the selection (_NONE, _SINGLE, _MULTIPLE).

	* folder-browser.c (got_folder): If the component is set,
	set our selection state to _NONE, because that's the default
	state of the ETree.
	(on_selection_changed): When the number of selected messages
	is updated, notify the FBUI code of our new state.
	(folder_browser_gui_init): Hook up to the selection_changed
	signal and default to the _NONE selection state.
	(done_message_selected): Notify when a message is loaded.

	* mail-folder-cache.c: Display how many messages are selected,
	too.
	(make_folder_status): If multiple messages are selected, add that
	to the string (the 0 and 1 cases are boring)
	(selection_changed): New function, update the selected count.
	(mail_folder_cache_note_fb): Connect to the selection_changed
	signal.
