g_signal_connect()

[Joao Rainha <jrainha olivia inesc-id pt>]

Hi!

I want to change a callback, on a button "clicked" signal for example, to 
another function during program running.

Can i simply do a g_signal_connect() to the new callback function, or do i 
have do "unreference" the old callback?
I can find this info on the man pages.

Thanks
