Obviously there is a lot about this in the QString documentation, including the workings of QString::arg() (http://doc.trolltech.com/4.6/qstring.html#arg).



QString("%1")

Creates a string with %1 as content.
.arg(int) replaces the lowest %N in the string it is called on with a string representation of the int.

The whole new string is then appended to str.

To convert string to int, use str.toInt().
