Re: Problem with sigc::bind

[Bob Caryl <bob fis-cal com>]

The compiler is complaining that class template
sigc::bound_argument<Gtk::Window&> has no member method named "visit". 
The docs at http://libsigc.sourceforge.net/ seem to make no mention of
this class at all. 

However, I found documentation of this class here:

http://www.spectronet.inf.br/Documentation/libsigc-2.0/docs/reference/html/classsigc_1_1bound__argument_3_01const__reference__wrapper_3_01T__wrapped_01_4_01_4.html

Since your compiler is finding this class, but not this member method, I
will have to defer to someone with more knowledge, like Muarry Cummings.
