Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

Indeed this is what the example does, because : 1- there is no Em processes registered 2- event is killed at first step. So, this unique step is always governed by hadronic interaction, according the exponential law.
Also, you will see how to extract hadronic cross sections from Geant4 data tables via G4HadronicProcessStore
In attachement, an example of macro and output
