It wants a pointer to something, so, we give it one:
gint dummy_int = 1;
gtk_signal_connect( GTK_OBJECT( robot_name[1] ), "clicked",
GTK_SIGNAL_FUNC( display_info ), &dummy_int );
...
void display_info( GtkWidget *was_clicked, gint *i )
{
cout << *i;
}
You might need to fuss a bit with a cast but it should be less
painful that what you've been through.
