Detailed Description

Provides a console windows, within the CamiTK application.

The console widget.

Usage:

#include <ConsoleStream.h>
 
...
 
// create your application
QApplication app(argc, argv);
 
// these redirect both cout/cerr
ConsoleStream cout(std::cout);
ConsoleStream cerr(std::cerr);
 
// now start using cout and cerr normally
 
std::cerr << "Oops"; // this goes to your debugger output

Potential problem on windows (see thread)

• std::string::clear() and std::string::push_back(...) don't exist, but myString.clear() can be substituted by myString.erase(myString.begin(), myString.end()) and myString.push_back(v) can be replaced by myString += v.
• The usage of int_type seems to require a using std::ios::int_type statement.
