This seems quite convoluted to me but I can't seem to make a more straight forward implementation work. The idea is that core code should never directly call into the UI. So instead the core code (this is C code) calls a helper function. That helper function calls a member function of a class which in return emits a signal. The UI code connects to that signal and acts accordingly when it is received. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
