Signals and slots are normalized - the const and references are
dropped. This means that both SIGNAL(linkClicked(QString)) and
SIGNAL(linkClicked(const QString &)) will work just fine. In fact, the
former is faster and is the convention you will find in Qt's own code.

The bug in the OP code is that he seems to have missed the SLOT macro.
I wonder how the code even compiles by just putting close_event() as
the slot argument.
