Qt Tile Stack On Click?

Hello Again,

I have spent the past two days trying to get this to work so I have decided to turn to the forums. The solution is probably super simple but how do I make an "on click" function for a tile stack?

Further Detail: The end result would be that you click on the tile stack or page of tile stack and a QMessageBox pops.
I am using Qt Creator so I would prefer it if I did not need to create a class for a brand new runtime tile stack

Thanks Guys,
Matt

P.S - Thanks for all of the support on this forum, it is much appreciated :D
