Re: Newbie question about signal handler args

[Antonio Gomes <tonikitoo gmail com>]

The (*data) IS a pointer (i think it's a 'void *' pointer ) to the
argToPass, and the *widget is a pointer to the "caller widget" ... So
, when button gets the focus in, this signal will be throwed, and the
callback 'buttonHandler' will the called ... To use the argToPass
inside the callback, just cast it to the desired type ...

>                               GTK_SIGNAL_FUNC( buttonHandler ), argToPass );
