Checking modifier keys at any moment

[Jarek Dukat <madmaxer poczta fm>]

I have a handler for GtkTreeView's row_activated and I'd like to check
there if at the moment of signal emision any modifier key (I'm mostly
interested in shift and mod1 keys) is pressed. Is there any gtk function
that returns current state of these keys at any moment?
I use Gtk+ 2.0.5.

struct Sig {
  string name("     J a r e k   D u k a t     ");
  string mail(" madmaxer (at) poczta (dot) fm ");
};
