+
+ More precisely, it defines:
+
+ - wxLog{FatalError,Error,Warning,Message,Verbose,Debug}() functions
+ taking the format string and additional vararg arguments if needed.
+ - wxLogGeneric(wxLogLevel level, const wxString& format, ...) which
+ takes the log level explicitly.
+ - wxLogSysError(const wxString& format, ...) and wxLogSysError(long
+ err, const wxString& format, ...) which log a wxLOG_Error severity
+ message with the error message corresponding to the system error code
+ err or the last error.
+ - 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
+ the message is the specified mask is enabled. This comes in two kinds:
+ Mask can be a wxString or a long. Both are deprecated.
+
+ In addition, wxVLogXXX() versions of all the functions above are also
+ defined. They take a va_list argument instead of "...".
