Trouble with QGraphicsTextItem events

[Flippik]

How can I check if the signal is emitted?
I've tried to do it as a link(stLabel3->setHtml("<a href=http://www.ya.ru>hello!!!</a>")),but nothing has changed..I've read the Assistant help for QGraphicsTextItem class reference and found only two signals that could be generated(linkActivated, linkHovered). Is it really to do this way or my efforts are useless?
kghose: I've not found anything useful for me...
