This will likely help you figure out how to set a non-static class member as a callback: http://www.nabble.com/Threading-Problem-t2341133.html Specifically, perhaps this will work: http://www.gtkmm.org/docs/glibmm-2.4/docs/reference/html/classGlib_1_1SignalIdle.html Signal handlers in Gtkmm are allowed to be non-static class members so maybe this would work for you.
