Detailed Description

template<class R, class... T>
class Glib::SignalProxyDetailedAnyType< R, T >

Proxy for signals with any number of 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

connect() [1/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::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

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.

connect() [2/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::connect ( SlotType&&  slot, bool  after = true  )

inline

Connects a signal handler to a signal.

See also

connect(const SlotType& slot, bool after).

Since glibmm 2.48:

connect_notify() [1/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::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

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.

connect_notify() [2/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::connect_notify ( VoidSlotType&&  slot, bool  after = false  )

inline

Connects a signal handler without a return value to a signal.

See also

connect_notify(const VoidSlotType& slot, bool after).
