+ - wxLogStatus(const wxString& format, ...) which logs the message into
+ the status bar of the main application window and its overload
+ wxLogStatus(wxFrame *frame, const wxString& format, ...) which logs it
+ into the status bar of the specified frame.
+ - wxLogTrace(Mask mask, const wxString& format, ...) which only logs
