SignalBase (const char *name, GCallback callback)

Detailed Description

Base class for the GTK+ C++ signal interface.

Constructor & Destructor Documentation

Xfc::G::SignalBase::SignalBase ( const char * name,

GCallback callback

) [protected]

Constructor.

Parameters:

name The GTK+ name for the signal.

callback The callback function to translate GObject signal emissions into sigc::slot calls.

Member Function Documentation

void Xfc::G::SignalBase::connect ( TypeInstance * instance,

const SlotBase & slot,

const char * detail,

bool after

) const [protected]

Connects slot to this signal through the callback specified in the constructor.

Parameters:

instance The object instance containing the signal.

slot The sigc::slot to connect to the signal.

detail The detail string to append to the signal name.

after Set true to call the user-defined slot after the signal, or false to let the signal's default behavior preside.

void Xfc::G::SignalBase::stop_emission ( TypeInstance * instance )

Stops the signal's current emission.

Parameters:

instance The object whose signal handlers you wish to stop.

This will prevent the default method from running, if the signal was G_SIGNAL_RUN_LAST and you connected normally (i.e. without the "after" flag). Prints a warning if used on a signal which isn't being emitted.
