The reason for doing this is that all object reference cycles should be broken at destruction time. + +* Signal system changes: + The Gtk 2.0 signal merly proxies the GSignal system now. + For future usage, direct use of the GSignal API is recommended, + this avoids significant performance hits where GtkArg structures + have to be converted into GValues. For language bindings, + GSignal+GClosure provide a much more flexible and convenient + mechanism to hook into signal emissions or install class default + handlers, so the old GtkSignal API for language bindings is not + supported anymore. + Functions that got removed in the Gtk signal API: + gtk_signal_n_emissions(), gtk_signal_n_emissions_by_name(), + gtk_signal_set_funcs(), gtk_signal_handler_pending_by_id(), + gtk_signal_add_emission_hook(), gtk_signal_add_emission_hook_full(), + gtk_signal_remove_emission_hook(), gtk_signal_query(). + gtk_signal_add_emission_hook(), gtk_signal_remove_emission_hook(). + Also, the GtkCallbackMarshal argument to gtk_signal_connect_full() is + not supported anymore. + For many of the removed functions, similar variants are available + in the g_signal_* namespace. - Inserting and deleting text in GtkEntry though functions such as gtk_entry_insert_text() now leave the cursor at its original |
