2002-08-09  Peter Williams  <peterw@ximian.com>

	* subscribe-dialog.c: Change this into a GnomeApp so we get a
	statusbar and the dialog is a little more comprehensible.

	* subscribe-dialog.c: (struct _FolderETree): Add members for
	tracking activity callback information.
	(get_short_folderinfo_got): Notify the activity callback.
	(subscribe_get_short_folderinfo): Here too.
	(folder_etree_init): Initialize the activity level to 0.
	(folder_etree_construct): Take new parameters of our activity
	callback and user_data.
	(folder_etree_new): Here too.
	(store_data_get_widget): Take the parameters here and pass them
	on.
	(sc_close_pressed): New callback for when close button is pressed.
	(sc_activity_timeout): New timeout to move the activity bar when
	folders are being scanned.
	(sc_activity_cb): If activity_level > 0, start the progressbar
	moving and set the status.
	(menu_item_selected): Pass the callback to store_data_get_widget.
	(subscribe_dialog_construct): Load some more widgets and adapt to
	some changes in the XML. Also connect the close button signal and
	initialize the progress bar's settings.

	* mail-callbacks.c (manage_subscriptions): Don't call
	gnome_dialog_set_close on it anymore since it's no longer a gnome
	dialog.
