2001-05-21 Chris Toshok <toshok@ximian.com> * menus/gal-view-menus.c (build_menus): make the view menuitems radio items of the same group, and allocate the closure here. (free_verbs): only need to free the one DefineViews verb here. (closure_free): new function - EListFreeFunc for our listenerClosure list. (remove_listeners): new function, free our listener list. (gvm_destroy): call remove_listeners. (gvm_init): init listenerClosures list. (toggled_cb): callback for radio items. (build_verbs): strip out almost all the code since there's only 1 verb now. (build_stuff): call remove_listeners. svn path=/trunk/; revision=9916
