Forgive my silly typo, I did mean std::string.
It is strange that now
std::string str = "This is the first line \n This is
the second line";
text->setText(str);
works!!!
I don't know why it failed two hours ago.
But if I change the str content with things read from external files, the \n
does not work again'(
When creating the external text files, I already added the breaker into the
contents.
Thanks anyway!!!
