      According to the plan there should be two elements, but only the first one is defined.

      QRegExp rx("\\d+"); QString buf_last; buf_last.append("read0_1"); 
rx.indexIn(buf_last); 
auto try_step = rx.cap(0).toInt();
auto current_step = rx.cap(1).toInt(); 

qDebug() << try_step << current_step << buf_last << "rx___" << rx.cap(0) << rx.cap(1) << rx.capturedTexts();

result:
0 0 "read0_1" rx___ "0" "" ("0")

       

      Working if used:

      QRegExp rx("(\\d+)");
