QtStrToInt is a conversion code snippet to convert a QString to an integer.

 

#include <cassert> #include <QString> //From http://www.richelbilderbeek.nl/CppQtStrToInt.htm int QtStrToInt(const QString& s) {   bool okay = true;   const int i = s.toInt(&okay);   assert(okay == true);   return i; } //From http://www.richelbilderbeek.nl/CppIntToQtStr.htm QString IntToQtStr(const int i) {   QString s;   s.setNum(i);   return s; } int main() {   assert(QtStrToInt("123")==123);   assert(IntToQtStr(123)=="123"); }
