Code cleanup: implement window title update via signal 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.

Cleanup: Make WindowsTitleUpdate a global object WindowsTitleUpdate is such a trivial object (a QObject with a single signal and no own state), that it's not really understandable why it would need all that "singleton" boiler-plate. Just make it a default constructed/destructed global object. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at> 2018-07-30 20:59:07 +02:00			`WindowTitleUpdate windowTitleUpdate;`
