I use:

std::cout << "some text << std::endl;

 If you do this, don't forget to

#include <iostream>

Hi,

qDebug() can't reach the console window of Momentics IDE by own. You must create a message handler, who will transfer qDebug() messages to the console. The easiest way is, to copy this method to your main.cpp file:

void myMessageOutput(QtMsgType type, const char *msg)
 {
     //in this function, you can write the message to any stream!
     switch (type) {
     case QtDebugMsg:
         fprintf(stderr, "Debug: %s\n", msg);
         break;
     case QtWarningMsg:
         fprintf(stderr, "Warning: %s\n", msg);
         break;
     case QtCriticalMsg:
         fprintf(stderr, "Critical: %s\n", msg);
         break;
     case QtFatalMsg:
         fprintf(stderr, "Fatal: %s\n", msg);
         abort();
     }
 }

 This will be the debug message handler. One thing is left: you must install this message handler for your application. Copy to the main() method this line of code right after the translator initialization:

qInstallMsgHandler(myMessageOutput);

cheers,

Please do not ship final apps with this stdour/stderr logging enabled.  It causes a performance hit because stdout/stderr are written to the flash disk while apps are running.

Consider only calling qInstallMsgHandler() in an #ifdef DEBIG condition or similar.

Cheers,

I have a check to avoid executing the statements, but you're right, I should have mentioned that
