@@blackiedk Sorry you misunderstood my comment. Stallio and Olio were a great close-knit duo, they did great things together. I have compared you because together you can see that you work well together. It was not my intention to offend.
@@piergiorgiovalli5220 No offense taken, I was just playing along on your joke. They indeed were very great actors, and adding Peppe to QWAM from time to time indeed does add a lot of value.
Thank you for another great video! Question: If directory, name, and extension are existing QStrings, how does the efficiency of QStringLiteral("%1/%2.%3").arg(directory, name, extension) compare to directory % "/" % name % "." % extension?
Hi, It's going to be the same (one allocation). Of course formatting via arg() offers some extra flexibility (e.g. easier to support translations). When in doubt, profile :-)

At 5:22 that shoud be with a + sign !? like: DEFINES += QT_USE_STRINGBUILDER ?
*= means that it will add it, only if it isn't in the list already. So had you written += instead you would risk to have it multiple times. Not a big deal your compiler will cope, just makes it harder to read your compiler output.

Stanlio e Ollio was a big duo,now there is a a new duo for technology Jesper and Angelo :-)
I can see why you would compare me to the fat guy with a temper, but Peppe really isn't that clumsy :-)
