How do I translate the NULLs in

  gtk_menu_popup (menu, NULL, NULL, window_list_position_menu, frame, 0, 0);

into scheme?

Things like:

  (popup menu #f #f ..)
  (popup menu '() '() ..)
  (popup menu 0 0 ..)

all yield

  <unnamed port>: In procedure gtk-menu-popup in expression (#<gw:dynproc 
gtk-menu-popup (7)> arg1 arg2 ...):
  <unnamed port>: Wrong type argument in position 2: ()

Jan.
