This isn't legal C given the signature of the function, plus you 
probably mean gtk_signal_connect(), not gtk_signal_connect_object().

Not like this. But yes.

Welcome to the C programming language.

A struct is one way. Another is to use gtk_object_set_data() and
gtk_object_get_data() to store and retrieve the data attached to some
GtkObject, such as the one emitting the "clicked" signal. Another is
global variables.
