You can just start your worker thread using std::async, std::thread or
Glib::Threads::Thread, and on completion the worker thread can post its
continuation to the glib main loop using
Glib::SignalIdle::connect_once(): see
https://developer.gnome.org/glibmm/2.52/classGlib_1_1SignalIdle.html

For something more formalized you could use
TaskManager::make_task_packaged_compose() from c++-gtk-utils:
