yes, just like all GTK+ signal handling functions. you have to gather
up the arguments into a struct, and pass a pointer to it when you
connect to the signal. hints:

	typedef struct {
	    int foo;
	    void *bar;
	    float baz;
        } MyStruct;

	MyStruct *ms = g_new (1, MyStruct);

	ms->foo = 1;
	ms->bar = ms;
	ms->baz = M_PI;

	gtk_signal_connect (GTK_OBJECT(button), "clicked",
			    (GtkSignalFunc) on_button_clicked,
			    (gpointer) ms);

        void on_button_clicked (GtkWidget *w, gpointer data)
	{
		MyStruct *ms = (MyStruct *) data;
		.... do something ...
        }
