Detailed Description

template<class R>
class Glib::SignalProxyDetailed0< R >

Proxy for signals with 0 arguments and possibly a detailed name.

Use the connect() or connect_notify() method, with sigc::mem_fun() or sigc::ptr_fun() to connect signal handlers to signals.

Member Function Documentation

template <class R >
sigc::connection Glib::SignalProxyDetailed0< R >::connect ( const SlotType slot,
bool  after = true 
)
inline

Connects a signal handler to a signal.

For instance, connect( sigc::mem_fun(*this, &TheClass::on_something) );

Parameters
slotThe signal handler, usually created with sigc::mem_fun() or sigc::ptr_fun().
afterWhether this signal handler should be called before or after the default signal handler.
template <class R >
sigc::connection Glib::SignalProxyDetailed0< R >::connect_notify ( const VoidSlotType slot,
bool  after = false 
)
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.

connect_notify( sigc::mem_fun(*this,& TheClass::on_something) );
connect( sigc::bind_return<bool>(sigc::mem_fun(*this, &TheClass::on_something), false), false );
Parameters
slotThe signal handler, which should have a void return type, usually created with sigc::mem_fun() or sigc::ptr_fun().
afterWhether this signal handler should be called before or after the default signal handler.
