Are any GUI libs going to make use of signals/slots?

I made a simple OpenGL based GUI for my little library that uses 
signal/slots (note I just recently completed it but haven't used it for 
any apps yet, except for test apps).

It makes it really easy for users to hook up their own custom code to 
handle things such as buttons being clicked.

One thing I'm curious about is the efficiency of signals and slots. I'm 
guessing it has slightly more overhead than a normal function call, 
therefore it is not something to be calling constantly.
