Re: [sigc] Connect signal to a signal?

[Régis Duchesne <hpreg vmware com>]

Folks,

From http://developer.gnome.org/libsigc++/stable/classsigc_1_1signal.html :
"If you want to connect one signal to another, use make_slot() to retrieve a functor that emits the signal when invoked."

So this can be done more nicely, with:
signal_a.connect(signal_b.make_slot());

Cheers,
