Swfdec - May 2010 - mouse press event

Hi to all,
i don't understand how i can to handle mouse press event?


i try this:

in the main : g_signal_connect (player, "handle-mouse", G_CALLBACK
(pressMouse), NULL);


my function is pressMouse:

gboolean  pressMouse(SwfdecPlayer *player,gdouble  x, gdouble y, gint
button, gpointer user_data )
{
  if (button)
  {
   swfdec_player_mouse_move(player , x, y);
    swfdec_player_mouse_press (player, x, y, button);
  }
 else if(button==-1)
  {
 swfdec_player_mouse_move(player , x, y);
    swfdec_player_mouse_release (player, x , y, button);
  }

 return FALSE;
}

my program failed with error : Segmentation fault (core dumped)


what's wrong here
