How to detect new line?

[whoops.slo]

This is the error the compiler is giving me after i had put in the document the sugested code... What went wrong?

glavni.cpp:449:34: macro "Q_FOREACH" requires 2 arguments, but only 1 given
glavni.cpp: In member function `void okno:n_o_t_izpis_clicked()':
glavni.cpp:449: error: `Q_FOREACH' undeclared (first use this function)
glavni.cpp:449: error: (Each undeclared identifier is reported only once for eac
h function it appears in.)
glavni.cpp:449: error: expected `;' before '{' token

Tnx!

What went wrong?

There should be "," instead of ";":

foreach( QString line, lines ) {
   // ...
}

foreach( QString line, lines ) {
   // ...
}

To copy to clipboard, switch view to plain text mode
