show tray icon with progress during lifetime of this instance
ATTENTION: wxWidgets never assumes that an object indirectly destroys itself while processing an event!
this includes wxEvtHandler-derived objects!!!
it seems ProcessEvent() works (on Windows), but AddPendingEvent() will crash since it uses "this" after the event processing!
=> don't derive from wxEvtHandler or any other wxWidgets object here!!!!!!
=> use simple std::function as callback instead => instance may now be safely deleted in callback!
