Paul Davis	968533cc23	(re)add mechanism for a callback in any glib event loop executed before the loop "executes" ... This is based on code from earlier commits that were later reversed, but we need some mechanism to ensure that threads have a thread local tempo map ptr set. The big difference is that this time we do not implement this for all instances of an AbstractUI - implementation is left to each thread/event loop	2022-05-16 15:24:52 -06:00

Paul Davis	09c84d1de8	add new GSource-derived object that can be attached to a Glib::MainContext to execute code before other sources have their dispatch() method invoked	2021-08-13 12:51:29 -06:00
