Detailed Description
template<class R, class... T>
class Glib::SignalProxy< R, T >
Proxy for signals with any number of arguments.
Use the connect() or connect_notify() method, with sigc::mem_fun() or sigc::ptr_fun() to connect signal handlers to signals.

Connects a signal handler to a signal.
For instance, connect( sigc::mem_fun(*this, &TheClass::on_something) );
- Parameters
-
slot The signal handler, usually created with sigc::mem_fun() or sigc::ptr_fun(). after Whether this signal handler should be called before or after the default signal handler.

Connects a signal handler to a signal.
|
inline |
Connects a signal handler without a return value to a signal.
By default, the signal handler will be called before the default signal handler.
For instance, connect_notify( sigc::mem_fun(*this, &TheClass::on_something) );
If the signal requires signal handlers with a void
return type, the only difference between connect() and connect_notify() is the default value of after.
If the signal requires signal handlers with a return value of type T, connect_notify() binds return T()
to the connected signal handler. For instance, if the return type is bool
, the following two calls are equivalent.
- Parameters
-
slot The signal handler, which should have a void
return type, usually created with sigc::mem_fun() or sigc::ptr_fun().after Whether this signal handler should be called before or after the default signal handler.
