signal_handlers_destroy()

[Mario Ospelt <mospelt student ethz ch>]

Hello,

I wanted to use the signal_handlers_destroy() method to remove the 
connected signals of my button. But something doesn't work. I always get 
this error:

Can't locate object method "signal_handlers_destroy" via package 
"Gtk2::Button"

Why can't the method be found? Is it spelled differently?

Thanks
Mario
