Check that view->view != NULL. (save_contact_cb): Check that view->view !=
2001-10-11 Jon Trowbridge <trow@ximian.com> * gui/component/addressbook.c (new_contact_cb): Check that view->view != NULL. (save_contact_cb): Check that view->view != NULL. (search_cb): Check that view->view != NULL. (delete_contact_cb): Check that view->view != NULL. (print_cb): Check that view->view != NULL. (print_preview_cb): Check that view->view != NULL. (stop_loading_cb): Check that view->view != NULL. (cut_contacts_cb): Check that view->view != NULL. (copy_contacts_cb): Check that view->view != NULL. (paste_contacts_cb): Check that view->view != NULL. (select_all_contacts_cb): Check that view->view != NULL. (send_contact_cb): Check that view->view != NULL. (send_contact_to_cb): Check that view->view != NULL. (update_command_state): Check that view->view != NULL. Hold a reference to the AddressbookView for the duration of the function, in case we exit during bonobo-reentrancy. (addressbook_view_ref): Added. (addressbook_view_unref): Added. Simple ref counting for AddressbookView objects. (addressbook_view_clear): Zero out an AddressbookView. This is now separated from the deallocation of the AddressbookView object, so that we don't leave a dangling pointer if we exit during bonobo-reentrancy in update_command_state. (Which often seems to happen if we exit while addressbook operations are going on.) (destroy_callback): Replace previous call to addressbook_view_free with addressbook_view_clear/addressbook_view_unref calls. (addressbook_factory_new_control): Initialize the reference count in the AddressbookView object. * gui/widgets/e-addressbook-view.c (e_addressbook_view_destroy): Carefully zero out our destroyed object. (command_state_change): Hold a reference to ourselves during the signal emission. (get_selected_cards): Ref cards as we add them to the list. (e_addressbook_view_stop): Check for view != NULL. (e_addressbook_view_can_create): Check for view != NULL. (e_addressbook_view_can_print): Check for view != NULL. (e_addressbook_view_can_save_as): Check for view != NULL. (e_addressbook_view_can_send): Check for view != NULL. (e_addressbook_view_can_send_to): Check for view != NULL. (e_addressbook_view_can_delete): Check for view != NULL. (e_addressbook_view_can_cut): Check for view != NULL. (e_addressbook_view_can_copy): Check for view != NULL. (e_addressbook_view_can_paste): Check for view != NULL. (e_addressbook_view_can_select_all): Check for view != NULL. (e_addressbook_view_can_stop): Check for view != NULL. * gui/widgets/e-addressbook-model.c (addressbook_destroy): Be careful about zeroing out our destroyed object. * backend/ebook/e-book-view.c (e_book_view_stop): Added. Stops event processing in the underlying listener. svn path=/trunk/; revision=13578
