(Moving the flag for has_changed from the Hdrs to the Composer itself.
2001-01-25 Jason Leach <jasonleach@usa.net> (Moving the flag for has_changed from the Hdrs to the Composer itself. Providing public methods to set/unset a composer as changed. Adding attachments now flags the composer as changed) * e-msg-composer.c (e_msg_composer_unset_changed): New function. (e_msg_composer_set_changed): New function. * e-msg-composer.c (hdrs_changed_cb): Callback to the new signal, uses the new composer_set_changed. (attachment_bar_changed_cb): Add a call to the new _set_changed. * e-msg-composer-hdrs.c (class_init): New signal "hdrs_changed" to tell the parent composer that any of the headers have changed. (addressbook_entry_changed): emit the new signal here. (entry_changed): And here. svn path=/trunk/; revision=7818
