TraceLog Class Reference

#include <TraceLog.h>

Detailed Description

TraceLog is a simple debugging tool which allows the programmer to write messages to glimsview_log.txt.

Messages are stored during runtime and written to the file when the GLIMSView application exits. Disabling this functionality is done simply by commenting out the code in this class that opens the file and stores messages for writing to the file. The TraceLog object, glimslog, is instantiated near main in the maintoolbar.cpp file. To use this object, include the TraceLog.h file, declare extern TraceLog glimslog in the function that will send it messages, and use glimslog.log(char * msg) or glimslog.log(string msg) to add a new message to the queue.

example of usage to print some information plus the of x to the log:

extern TraceLog glimslog ; std::stringstream logstream ; logstream << "Message text " << x << endl ; glimslog.log( logstream.str() ) ; logstream.str("") ;
