In order to convert a QString to a char*, then you first need to get a latin1 representation of the string by
calling toLatin1() on it which will return a QByteArray. Then call data() on the QByteArray to get a pointer to
the data stored in the byte array.
int main(int argc, char **argv) { QApplication app(argc, argv); QString str1 = "Test"; QByteArray ba = str1.toLatin1(); const char *c_str2 = ba.data(); return app.exec(); }
To convert a char* to a QString you can use the QString constructor that takes a QLatin1String, e.g:
QString string = QString(QLatin1String(c_str2)) ;
