Detailed Description

This class provides some static methods for printing debugging information to stderr.

The methods accept a format string and parameters in the same way as the printf functions from standard C.

Messages can be logged with different priorities.

While there is no restriction as to what is logged, it is a good idea to log the class name and function name first.

   // output for development:
   qDebug("RMyClass::myFunction: i = %d", i);
   // warnings ("this should not happen under normal cicumstances"):
   qWarning("RMyClass::myFunction: cannot open file '%s'", fileName);
   // indication for a bug in the application:
   qWarning("RMyClass::myFunction: parent is NULL. Aborting.");

Scriptable:

This class is wrapped for script environments.
