Two things: do you REALLY want to quit/close the application/dialog when the user clicks upon a LINK / URL? A push button would be the expected GUI element...

But assuming you REALLY want the user to click on an URL to CLOSE the dialog (or even the application main window, depending on what 'this' refers to), then check again the Qt docs very carefully:

  http://doc.trolltech.com/4.7/qlabel.html#signals

See the '&' in the argument list? ;) That means that a REFERENCE to a QString is passed along, NOT a QString! When you check the output (on stdout/err) I would strongly expect that you see a "No such slot" message! ;)


But again, I strongly suspect what you are really after is a http://doc.trolltech.com/4.7/qpushbutton.html ...
