GtkActionEntry doesn't allow closures?

[Jason Hickey <jyh cs caltech edu>]

I am developing a GTK+ binding for OMake (http://omake.metaprl.org).   
OMake has a functional language, so it has closures, etc.

Pardon me if I am daft, but,
   - One cannot simply pass a GClosure where a GCallback is expected  
(!?).

GTK+ is usually nice--each signal can be paired with data, making it  
easy to form closures.

Am I missing something, or is it not possible to deal with closures  
in GtkActionEntry?

struct _GtkActionEntry
{
  const gchar *name;
  const gchar *stock_id;
  const gchar *label;
  const gchar *accelerator;
  const gchar *tooltip;
  GCallback callback;    /* Ummm, what about closures? */
};

BTW, thank you for GTK+, "thou art god" as Heinlein might say.

Jason
