Message definition (Development/Tutorials/Common Programming Mistakes)

The expensive thing happening here is the conversion to {{qt|QString}}, which does a conversion to Unicode internally. This is unnecessary because, the first thing the method does is convert it back using <tt>toLatin1()</tt>. So if you are sure that the Unicode conversion is not needed, try to avoid inadvertently using QString along the way.
