I'm curious why? Other than, I guess, that being more familiar than

I also suspect you'll need to pass that as std::ref(*this), otherwise I
think sigc++ will assume you want a copy, which is unlikely to end well.

I'm trying to call a function that accepts one parameter when user
clicks a menu item. I tried this:
menu_item.signal_activate().connect(sigc::bind(sigc::ptr_fun(&handler_fun),

Gtk::Window. The handler_fun function does not be
