I am trying to add a module interface to some of the bits missing from
PyGtk2. Some functions I'm interested in have varargs signatures, e.g.:
void
gtk_binding_entry_add_signal (GtkBindingSet *binding_set,
guint keyval,
guint modifiers,
const gchar *signal_name,
guint n_args,
...)
>From Python, this would be called something like
bs = gtk.GtkBindingSet("somename")
bs.add_signal(gtk.GDK.K_Up, 0, "scroll_vertical",
gtk.TYPE_ENUM, gtk.SCROLL_STEP_BACKWARD,
gtk.TYPE_FLOAT, 0.0)
with n_args inferred from the number of arguments following the
"scroll_vertical" parameter. I'm a bit stumped how to handle this with the
PyArg_Parse* routines. (I'll worry about calling
gtk_binding_entry_add_signal after I figure out how to marshal the args.)
The only place in the standard modules I saw that processed a truly
arbitrary number of arguments is the struct_pack method of the struct
module, and it doesn't use PyArg_Parse* to process them. Can someone point
me to an example of marshalling arbitrary numbers of arguments then calling
a varargs function?
Thx,
